Driverless car

The driverless car concept embraces an emerging family of highly automated cognitive and control technologies, ultimately aimed at a full "taxi-like" experience for car users, but without a human driver.

Driverless passenger programs include the 800 million ECU EUREKA Prometheus Project on autonomous vehicles (1987-1995), the [http://www.2getthere.eu 2getthere] passenger vehicles (using the FROG-navigation technology) from the Netherlands, the ARGO research project from Italy, and the DARPA Grand Challenge from the USA. For the wider application of artificial intelligence to automobiles see "smart cars".

History

The history of autonomous vehicles starts in 1977 with the Tsukuba Mechanical Engineering Lab in Japan. On a dedicated, clearly marked course it achieved speeds of up to 30 km/h (20 miles per hour), by tracking white street markers (special hardware was necessary, since commercial computers were much slower than they are today). In the 1980s a vision-guided Mercedes-Benz robot van, designed by Ernst Dickmanns and his team at the Universität der Bundeswehr in Munich, Germany, achieved 100 km/h on streets without traffic. Subsequently, the European Commission began funding the 800 million Euro EUREKA Prometheus Project on autonomous vehicles (1987-1995).

Also in the 1980s the DARPA-funded Autonomous Land Vehicle (ALV) in the United States achieved the first road-following demonstration that used laser radar (Environmental Research Institute of Michigan), computer vision (Carnegie Mellon University and SRI), and autonomous robotic control (Carnegie Mellon and Martin Marietta) to control a driverless vehicle up to 30km/h.

In 1994, the twin robot vehicles VaMP and Vita-2 of Daimler-Benz and Ernst Dickmanns of UniBwM drove more than one thousand kilometers on a Paris three-lane highway in standard heavy traffic at speeds up to 130 km/h, albeit semi-autonomously with human interventions. They demonstrated autonomous driving in free lanes, convoy driving, and lane changes left and right with autonomous passing of other cars.

In 1995, Dickmanns´ re-engineered autonomous S-Class Mercedes-Benz took a 1600 km trip from Munich in Bavaria to Copenhagen in Denmark and back, using saccadic computer vision and transputers to react in real time. The robot achieved speeds exceeding 175 km/h on the German Autobahn, with a mean time between human interventions of 9km, or 95% autonomous driving. Again it drove in traffic, executing manoeuvres to pass other cars. Despite being a research system without emphasis on long distance reliability, it drove up to 158 km without human intervention.

In 1995, the Carnegie Mellon University Navlab project achieved 98.2% autonomous driving on a 5000 km (3000-mile) "No hands across America" trip. This car, however, was semi-autonomous by nature: it used neural networks to control the steering wheel, but throttle and brakes were human-controlled. From 1996-2001, the Italian government funded the [http://www.argo.ce.unipr.it/ARGO/english/ ARGO] Project at University of Parma and Pavia University (coordinated by [http://www.ce.unipr.it/~broggi/ Prof. Alberto Broggi] ), which worked on enabling a modified Lancia Thema to follow the normal (painted) lane marks in an unmodified highway. The culmination of the project was a journey of 2,000 km over six days on the motorways of northern Italy dubbed [http://millemiglia.ce.unipr.it/ARGO/english MilleMiglia in Automatico] , with an average speed of 90 km/h. 94% of the time the car was in fully automatic mode, with the longest automatic stretch being 54 km. The vehicle had only two black-and-white low-cost video cameras on board, and used stereoscopic vision algorithms to understand its environment, as opposed to the "laser, radar - whatever you need" approach taken by other efforts in the field.

Three US Government funded military efforts known as Demo I (US Army), Demo II (DARPA), and Demo III (US Army), are currently underway. Demo III (2001) [cite web |url=http://www.isd.mel.nist.gov/documents/albus/4DRCS.pdf |title=4-D/RCS reference model architecture for unmanned ground vehicles] demonstrated the ability of unmanned ground vehicles to navigate miles of difficult off-road terrain, avoiding obstacles such as rocks and trees. James Albus at NIST provided the Real-Time Control System which is a hierarchical control system. Not only were individual vehicles controlled (e.g. throttle, steering, and brake), but groups of vehicles had their movements automatically coordinated in response to high level goals.

In 2002, the DARPA Grand Challenge competitions were announced. The competitions allowed international teams to compete in fully autonomous vehicle races over rough unpaved terrain and in a non-populated suburban setting.

The challenge

The challenges can broadly be divided into the technical and the social. The technical problems are the design of the sensors and control systems required to make such a car work. The social challenge is in getting people to trust the car, getting legislators to permit the car onto the public roads, and untangling the legal issues of liability for any mishaps with no person in charge.

However, any solution can be broken down to four sub-systems:
*sensors: the car knows where an obstacle is and what is around it;
*navigation: how to get to the target location from the present location;
*motion planning: getting through the next few meters, steering, and avoiding obstacles while also abiding by rules of the road and avoiding harm to the vehicle and others;
*control of the vehicle itself: actuating the system's decisions.

In examining every proposed solution, one should look at the following questions:
*Is this truly a complete system? Does it drive itself door-to-door?
*To what degree is the proposed solution a step towards the complete vision, or is it just a trick?
*Is the car 'autonomous', or would it need changes to the infrastructure?
*How feasible (technically, economically, and politically) would it be to deploy the entire solution?
*Can the system allow for and include existing vehicles driven by humans, or does it need an open field?
*How would it cope with unexpected circumstances?

Some have argued that the problem is AI-complete -- that a safe and reliable driverless car would need to use "all" the skills of an ordinary human being, including commonsense reasoning and affective computing. The concern is that driverless cars will perform worse than human beings in emergency situations that require judgement and the ability to communicate with other drivers and police. For example, how should a driverless car react to a person waving a flare in the middle of the road?

Recent projects

The work done so far varies significantly in its ambition and its demands in terms of modification of the infrastructure. Broadly, there are three approaches:
*Fully autonomous vehicles
* Various enhancements to the infrastructure (either an entire area, or specific lanes) to create a self-driving closed system.
*"assistance" systems that incrementally remove requirements from the human driver (e.g. improvements to cruise control)

An important concept that cuts across several of the efforts is vehicle platoons. In order to better utilize road-space, vehicles are assembled into ad-hoc train-like "platoons", where the driver (either human or automatic) of the first vehicle makes all decisions for the entire platoon. All other vehicles simply follow the lead of the first vehicle.

Fully autonomous

They require a car to drive itself to a pre-set target using un-modified infrastructure. The final goal of safe door-to-door transportation in arbitrary environments is not yet reached though.

Vehicles for paved roads

* The 800 million Euro EUREKA Prometheus Project on autonomous vehicles (1987-1995). Among its culmination points were the twin robot vehicles VITA-2 and VaMP of Daimler-Benz and Ernst Dickmanns, driving long distances in heavy traffic (see #History above).
*The third competition of the DARPA Grand Challenge held in November 2007. 53 teams qualified initially, but after a series of qualifying rounds, only eleven teams entered the final race. Of these, six teams completed navigating through the non-populated urban environment, and the Carnegie Mellon University team won the $2 million prize.
* ARGO

Free-ranging military vehicles

There are three clusters of activity relating to free-ranging off-road cars. Some of these projects are military-oriented.

*US military DARPA Grand Challenge

:The US Department of Defense announced on the July 30, 2002 a "Grand Challenge", for US-based teams to produce a vehicle that could autonomously navigate and reach a target in the desert of the south western USA. :In March 2004, the first competition was held, for a prize-money of $1 million. Not one of the 25 entrants completed the course. However, in the second competition held in October 2005 five different teams completed the 135-mile (217 km) course, and the Stanford University team won the $2 million prize.

:November 3rd, 2007, the third competition was held and $3.5 million dollar in cash prizes, trophys and medals were awarded. Six driverless vehicles were able to complete the 55 miles of urban traffic in the 2007 DARPA Urban Challenge rally style race. 1st Place - Tartan Racing, Pittsburgh, PA; 2nd Place - Stanford Racing Team, Stanford, CA; 3rd Place - Victor Tango, Blacksburg, VA. More details available at http://www.darpa.mil/grandchallenge

*European Land-Robot Trial (ELROB):The German Department of Defense held an exhibition trade show (ELROB) for demonstrating automated vehicles in May 2006. The event included various military automated and remotely-operated robots, for various military uses. Some of the systems on display could be ordered and implemented immediately. In August 2007 a civilian version of the event was held in Switzerland.

: [http://smart-team.ch/ The Smart team] from Switzerland presented "a Vehicle for Autonomous Navigation and Mapping in Outdoor Environments". For pictures of their ELROB demo, see [http://www.fgan.de/~elrob2006/MELROB/2006/images/Lausanne/index.html this] .
*The Israeli Military-Industrial Complex:As a followup from its success with Unmanned Combat Air Vehicles, and following the construction of the Israeli West Bank barrier there has been significant interest in developing a fully automated border-patrol vehicle. Two projects, by [http://www.elbitsystems.com/newsRoomPressRin.asp?s=1&id=83&pr=1&s_year=2004&s_month=all Elbit Systems] and [http://www.iai.co.il/Default.aspx?docID=31663&FolderID=17483&lang=en&res=0&pos=0 Israel Aircraft Industries] are both based on the locally-produced [http://www.defense-update.com/products/t/tomcar-armored.htm Armored "Tomcar"] and have the specific purpose of patrolling barrier fences against intrusions.

:The "SciAutonics II" team in the 2004 DARPA Challenge used Elbit's version of the Tomcar.

Pre-built infrastructure

The following projects were conceived as practical attempts to use available technology in an incremental manner to solve specific problems, like transport within a defined campus area, or driving along a stretch of motorway. The technologies are proven, and the main barrier to widespread implementation is the cost of deploying the infrastructure. Such systems already function in many airports, on railroads, and in some European towns.

Dual mode transit - monorail

There is a family of projects, all currently still at the experimental stage, that would combine the flexibility of a private automobile with the benefits of a monorail system. The idea is that privately-owned cars would be built with the ability to dock themselves onto a public monorail system, where they become part of a centrally managed, fully computerized transport system—more akin to a driverless train system (as already found in airports) than to a driverless car. This idea is also known as Dual mode transit. (See also Personal rapid transit for another interesting concept along those lines, for purely public transport.)

Groups working on this concept are:
* [http://www.ruf.dk/ RUF] (Denmark)
* [http://www.buick.co.uk/biway/ BiWay] (UK)
* ATN (New Zealand)
* [http://www.tritrack.net/ TriTrack] (Texas, United States)

Automated highway systems

Automated highway systems (AHS) are an effort to construct special lanes on existing highways that would be equipped with magnets or other infrastructure to allow vehicles to stay in the center of the lane, while communicating with other vehicles (and with a central system) to avoid collision and manage traffic. Like the dual-mode monorail, the idea is that cars remain private and independent, and just use the AHS system as a quick way to move along designated routes. AHS allows specially equipped cars to join the system using special 'acceleration lanes' and to leave through 'deceleration lanes'. When leaving the system each car verifies that its driver is ready to take control of the vehicle, and if that is not the case, the system parks the car safely in a predesignated area.

Some implementations use radar to avoid collisions and coordinate speed.

One example that uses this implementation is the [http://www.pbs.org/wgbh/nova/escape/piocar.html AHS demo] of 1997 near San Diego, [http://www.tfhrc.gov/pubrds/july97/demo97.htm sponsored by the US government] , in coordination with the State of California and [http://www.cs.cmu.edu/Groups/ahs/ Carnegie Mellon University] . The test site is a 12-kilometer, high-occupancy-vehicle (HOV) segment of Interstate 15, 16 kilometers north of downtown San Diego. The event generated much [http://www.govtech.net/magazine/story.php?id=95445&issue=10:1997 press] [http://www.memagazine.org/backissues/may98/features/smarter/smarter.html coverage] . The technology is the [http://faculty.washington.edu/~jbs/itrans/ahstoc.htm subject] of a [http://www.amazon.com/gp/product/0306454696 book] .

This [http://www.tfhrc.gov/pubrds/fall96/p96au46.htm concerted effort] by the US government seems to have been pretty much [http://faculty.washington.edu/jbs/itrans/bishopahs.htm abandoned] because of social and political forces,above all else the desire to create a less futuristic and more marketable solution.

As of 2007, a three-year project is underway to allow robot controlled vehicles, including buses and trucks, to use a special lane along 20 Interstate 805. The intention is to allow the vehicles to travel at shorter following distances and thereby allow more vehicles to use the lanes. The vehicles will still have drivers since they need to enter and exit the special lanes. The system is being designed by Swoop Technology, based in San Diego county.

Free-ranging on grid

[http://www.frog.nl/ Frog Navigation Systems] (the Netherlands) applies the FROG (free-ranging on grid) technology. The technology consists of a combination of autonomous vehicles and a supervisory central system. The company's purpose-built electric vehicles locate themselves using odometry readings, recalibrating themselves occasionally using a "maze" of magnets embedded in the environment, and GPS. The cars avoid collisions with obstacles located in the environment using laser (long range) and ultra-sonic (short-range) sensors.

The vehicles are completely autonomous and plan their own routes from A to B. The supervisory system merely administers the operations and directs traffic where required. The system has been applied both indoors and outdoors, and in environments where 100+ automated vehicles are operational (container port). At this time the system is not suited yet for running the sheer number of vehicles encountered in urban settings. The company also has no intention of developing such technology at this time.

The FROG system is deployed for industrial purposes in factory sites, and is marketed as a pilot public transport system in the city of Capelle aan den IJssel by its subsidiary [http://www.2getthere.eu 2getthere] . This system experienced an [http://www.wolfstad.com/2005/12/driveless-robot-busses-crash/ accident] that proved to be caused by a [http://www.wolfstad.com/2005/12/driverless-robot-buses-crash-part-2/ Human error] .

Frog Navigation Systems is one of few fully commercial companies in this field.

Driver-assistance

Though these products and projects do not aim explicitly to create a fully autonomous car, they are seen as incremental stepping-stones in that direction. Many of the technologies detailed below will probably serve as components of any future driverless car — meanwhile they are being marketed as gadgets that assist human drivers in one way or another. This approach is slowly trickling into standard cars (e.g. improvements to cruise control).

Driver-assistance mechanisms are of several distinct types, sensorial-informative, actuation-corrective, and systemic.

Sensorial-informative

These systems warn or inform the driver about events that may have passed unnoticed, such as
*Lane Departure Warning System (LDWS), for example from [http://www.iteris.com/ldws.aspx Iteris] , see also [http://www.calccit.org/itsdecision/serv_and_tech/Collision_avoidance/lateral.html this overview] .
*Rear-view alarm, to detect obstacles behind. [http://www.echomaster.com/products.htm This system] gets activated when the reverse gear is engaged.
*Visibility aids for the driver, to cover blind spots and enhanced vision systems such as radar, wireless vehicle safety communications and night vision.
*Infrastructure-based, driver warning/information-giving systems, such as those developed by the Japanese government

Actuation-corrective

These systems modify the driver's instructions so as to execute them in a more effective way, for example the most widely deployed system of this type is ABS; conversely power steering is not a control mechanism, but just a convenience - it is not involved in decision making.
*Anti-lock braking system (ABS) (also Emergency Braking Assistance (EBA), often coupled with Electronic brake force distribution (EBD), which prevents the brakes from locking and losing traction while braking. This shortens stopping distances in most cases and, more importantly, allows the driver to steer the vehicle while braking.
*Traction control (TCS) actuates brakes or reduces throttle to restore traction if driven wheels begin to spin.
*Four wheel drive (AWD) with a centre differential. Distributing power to all four wheels lessens the chances of wheel spin. It also suffers less from oversteer and understeer.
*Electronic Stability Control (ESC)(also known for Mercedes-Benz proprietary Electronic Stability Program (ESP), Acceleration Slip Regulation (ASR) and Electronic differential lock (EDL)). Uses various sensors to intervene when the car senses a possible loss of control. The car's control unit can reduce power from the engine and even apply the brakes on individual wheels to prevent the car from understeering or oversteering.
*Dynamic steering response (DSR) corrects the rate of power steering system to adapt it to vehicle's speed and road conditions.

Note: The electronic differential lock (EDL) employed by Volkswagen is not - as the name suggests - a differential lock at all. Sensors monitor wheel speeds, and if one is rotating substantially faster than the other (i.e. slipping) the EDL system momentarily brakes it. This effectively transfers all the power to the other wheel [cite web

Systemic

*Automatic parking: e.g. [http://www.i4u.com/article590.html technology from Toyota] selling for [http://www.local6.com/technology/8458908/detail.html $700, with a 70% take-up rate.] The Lexus LS can park itself (parallel/reverse) via the 'Advanced Parking Guidance System' – though only controlling the steering.
*Follow another car on a motorway ("Enhanced" or "adaptive" cruise control), like The [http://www.ford.com/en/innovation/safety/accidentAvoidance/adaptiveCruiseControl.htm Ford] , Honda or [http://www.autoexpress.co.uk/news/62349/driverless_vectra_is_go.html Vauxhall] (GM).
* Nissan's [http://www.nissan-global.com/EN/NEWS/2006/_STORY/060315-01-e.html "Distance Control assist"]
*Death Brake; there is a move to introduce deadman's braking into automotive application, primarily heavy vehicles, and there may also be a need to add penalty switches to cruise controls.

A good collection of these technologies is available at Automotive component manufacturers' websites, such as [http://www.siemensvdo.com/topics/propilot/ Siemens VDO Automotive] or [http://delphi.com/ Delphi] (subsidiary of GM).

Existing and missing technologies

In order to drive a car, a system would need to:
# Understand its immediate environment (Sensors)
# Know where it is and where it wants to go (Navigation)
# Find its way in the traffic (Motion planning)
# Operate the mechanics of the vehicle (Actuation)Arguably, 2 1/2 of these problems are already solved: Navigation and Actuation completely, and Sensors partially, but improving fast. The main unsolved part is the motion planning.

Sensors

Sensors employed in driverless cars vary from the minimalist ARGO project's monochrome stereoscopy to [http://www.mobileye.com mobileye] 's inter-modal (video, infra-red, laser, radar) approach. The minimalist approach imitates the human situation most closely, while the multi-modal approach is "greedy" in the sense that it seeks to obtain as much information as is possible by current technology, even at the occasional cost of one car's detection system interfering with another's.

[http://www.mobileye.com Mobileye] is a company which makes detection systems for cars, which are currently only used for driver assistance, but are eminently suitable for a full-fledged driverless car. [http://mobileye.com/clips/bike_cut.mpg This video] demonstrates the capabilities of the system: all pedestrians, cars, motorbikes etc. are clearly displayed in video, with a frame around them and the distance between "our" car and the object observed. The system also detects the objects' motion (direction and speed) and can so calculate relative speeds, and predict collisions.

Navigation

The ability to plot a route from where the vehicle is to where the user wants to be has been available for several years. These systems, based on the US military's Global Positioning System are now available as standard car fittings, and use satellite transmissions to ascertain the current location, and an on-board street database to derive a route to the target. The more sophisticated systems also receive radio updates on road blockages, and adapt accordingly.

See the main article on Automotive navigation systems.

Motion Planning

http://www.youtube.com/watch?v=R8EWHndSn34
http://marsrovers.nasa.gov/gallery/video/movies/mer_rovernav_240Cap.mov (video on autonomous navigation)
This is current research problem. See the main article on the subject Motion planning.

Control of vehicle

As automotive technology matures, more and more functions of the underlying engine, gearbox etc. are no longer directly controlled by the driver by mechanical means, but rather via a computer, which receives instructions from the driver as inputs and delivers the desired effect by means of electronic throttle control, and other drive-by-wire elements. Therefore, the technology for a computer to control all aspects of a vehicle is well understood.

Work done in simulation

While developing control systems for real cars is very costly in terms of both time and money, much work can be done in simulations of various complexity. Systems developed using simpler simulators can gradually be transferred to more complex simulators, and in the end to real vehicles. Some approaches that rely on learning requires starting in a simulation to be viable at all, for example evolutionary robotics approaches - see [http://togelius.blogspot.com/2006/04/evolutionary-car-racing-videos.html this example] .

Social issues

There are also some social issues to address, such as
* Getting people to trust the car
* Getting legislators to permit the car onto the public roads
* Untangling the legal issues of liability for any mishaps with no person in charge.
* Despair of progress in the foreseeable future: The UK government seems to see little progress until 2056. See [http://networks.silicon.com/mobile/0,39024665,39155962,00.htm Silicon Networks article] and [http://news.cnet.co.uk/networking/0,39029686,49249085,00.htm CNET.co.uk News] .
* Getting people to give up their freedom to drive wherever they want, whenever they want without the aide of a computer - though mixed systems with some human driven and some computer driven cars are possible.

Motivations

As nearly all car crashes (particularly fatal ones) are caused by human driver error, driverless cars would effectively eliminate nearly all hazards associated with driving as well as driver fatalities and injuries (travelling by car is currently one of the most deadly forms of transportation, with over a million deaths annually worldwide). This would be especially helpful to people that drive to bars and inebriate themselves; the ability for a car to shuttle them home would practically eliminate drunk driving crashes.

Having the equivalent of a personal chauffeur would be a great convenience:
*Time spent commuting could be used for work, leisure, or rest.
*Parking in difficult areas becomes less of a concern as the car can park itself away from a busy airport, for example, and come back when called on a cell-phone.
*Taxiing children to school, activities and friends would become solely a matter of granting permission for the car to handle the child's request.
*Allow the visually (and otherwise) impaired to travel independently.
* One could sleep overnight during long road trips.

A driverless car would also be a boon to economic efficiency, as cars can be made lighter and more space efficient with the absence of some of the safety technologies rendered redundant with computerized driving. Also the technology would make transportation more efficient and reliable: there may be autonomous or remote-controlled delivery trucks dispatched around the clock to pick up and deliver goods. Moreover, driverless cars would reduce traffic congestion by allowing cars to travel faster and closer together.

Social Costs

The social costs of this innovation are similar to those of other past technologies: Unemployment, expense and the elimination of the "old way of doing things". See also Luddites.

As with any new labor-saving technology, this would lead to mass layoffs in the driving, cargo, and distribution industries. Taxis would also be automated, effectively eliminating a source of income for the less skilled. A similar if smaller impact is expected in the roadside-catering and other ancillary businesses. However, history shows that any such economic impact on jobs often leads to economic benefits elsewhere that create employment, though often not for the exact same people displaced by the new technology.

In order to recoup the development costs, and in order to maximise the profit opportunity that any exciting novelty presents, driverless cars will initially be significantly more expensive than manual cars.

However, the overall technology need not be limited to the operation of vehicles. Once successfully implemented for vehicles, this technology could be used to implement all sorts of routine personal and labor assistants for humans. The concept of "machine" would take on a whole new meaning.

Driving as a personal hobby and sport, and indeed the entire car-oriented sub-culture would be effectively eliminated. However, for those willing to pay for the extra feature, there could be an option to switch between manual and automated driving to make up for that.

Discussion & Future

Some systems control everything centrally, and in some the vehicle is truly autonomous in the sense that it "thinks" about its own situation in the first person - such a system can integrate with Humans that think in first person.

Conversely. a system that centrally manages everything, though easier to build from a conceptual and engineering point of view, would face horrendous economic barriers because of the costs of converting an entire city or country to the new system at once. In order to be compatible with humans the "first person" point of view is key. This is for three reasons:
# a distributed scheme in which each component (car) takes care of itself reduces complexity
# a system that has the concept of first-person operation can understand what a human driver is up to.
# for the human driver to understand what the driverless car is doing, it needs to operate and "think" in as similar a way to a human as practical (and safe).

Key players

International

The European Union has a multi-billion Euro programme to support Research and Development by ad-hoc consortia from the various member countries, called Framework Programmes for Research and Technological Development. Several of these projects pertain to the subject of driverless cars, e.g.:
*The [http://www.cybercars.org CyberCars] project gathered much useful data about the actual and possible deployments of Driverless Cars for public transport. The main system discussed is based on [http://www.frog.nl/ FROG] .

Many of the EU-sponsored projects are coordinated by a group called [http://www.ertico.com/en/about_ertico/organisation/ertico_team.htm Ertico] .

There are several national associations around the world that are active in research in the field of intelligent transportation systems, a term that seems to encompass anything which applies technology to the improvement of transport. In recent years there has been a trend in this field to move efforts away from the more visionary projects, such as driverless cars, to the more short-term, such as public transport and traffic management. Many of these organizations are government sponsored, and they all cooperate at some level or another. Some of the countries involved are: [http://www.itsa.org/new.nsf/vHomePage/$first!OpenDocument the USA] , [http://www.its-australia.com.au/kmxserver3/ Australia] , [http://www.itskorea.or.kr/eng/index.html Korea] (south), [http://www.its-taiwan.org.tw/ Taiwan] , [http://www.itsindia.org/its/index.htm India] --(specifically [http://www.itsindia.org/iv/index.htm Intelligent vehicles] ),and [http://www.its.go.jp/ITS/topindex/topindex_g02.html Japan] , specifically a [http://www.its.go.jp/ITS/topindex/topindex_g03_2.html cruise assist effort] (see below).A more complete list of its organizations can be found [http://www.ibec-its.org/links.htm here] .

In film

*The 1989 film "Batman", starring Michael Keaton, the Batmobile is shown to be able to drive itself to Batman's current location.
*The 1990 film "Total Recall", starring Arnold Schwarzenegger, features taxis apparently controlled by artificial intelligence; it is not clear, however, whether these are truly autonomous vehicles or simply conventional vehicles driven by androids.
*The 1994 film "Timecop", starring Jean-Claude Van Damme, set in 2004 and 1994, has cars that can either be self-driven or commanded to drive to specific locations such as "home".
*Another Arnold Schwarzenegger movie, "The 6th Day" (2000), features a driverless car in which Michael Rapaport sets the destination and vehicle drives itself while Rapaport and Schwarzenegger converse.
*The 2002 film "Minority Report", set in Washington, D.C. in 2054, features an extended chase sequence involving driverless personal cars. The vehicle of protagonist John Anderton is transporting him when its systems are overridden by police in an attempt to bring him into custody; Anderton is unable to control the vehicle, and has to break out of it to evade the authorities.
*The 2004 film "I, Robot" features vehicles with automated driving on future highways, allowing the car to travel safely at higher speeds than if manually controlled. An interesting concept of automated driving in this film is that people aren't trusted to drive manually, as opposed by people not trusting automated driving nowadays.
*Kitt, the automated TransAm in the TV series "Knight Rider" could drive by itself upon command
