Products with TTP

This page shows some of the products, in which the time-triggered protocol TTP is used.

TTP was successfully introduced in a production program in 2002. By now it is implemented in several commercial applications of the transportation and automation industries.

=Railway Signalling=

Thales Rail Signalling Solutions

The electronic interlocking system “LockTrac 6131 ELEKTRA” was designed within a cooperation of Thales Rail Signalling Solutions division and TTTech.

LockTrac 6131 ELEKTRA is an electronic interlocking system that provides the highest levels of safety and availability. The system is approved according to CENELEC standards with safety integrity level 4 (SIL4) and offers basic interlocking functions, local and remote control, automatic train operation, integrated block functionality and an integrated diagnosis system. LockTrac 6131 has two software channels with diverse software, to ensure the high safety requirements. Before getting transmitted externally, the data are checked in the safety channel. A diagnosis device saves all relevant information to allow efficient maintenance in case of failure.

=FADEC=

Aermacchi M346

The MAC-based FADEC is scalable, adaptable and fault-tolerant. The key technology enabler in this new FADEC is the use of TTP for inter-module communication. TTP removes the complex interdependencies among modules, simplifying initial application development as well in-service changes and upgrades. It allows all modules in a system to see all data all of the time, thus ensuring seamless fault accommodation without complex channel change logic.

Lockheed Martin F-16

TTP-based Modular Aerospace Control (MAC), which is a part of the F110 full authority digital engine control (FADEC) system of General Electric, is integrated on the Lockheed Martin F-16 fighter aircraft.

TTP, which is used as a backplane bus, supports high levels of engine safety, operational availability and reduced life cycle cost. A significant advantage is that all information on the bus is available to both FADEC channels simultaneously.

=Environmental Systems=

Airbus A380

For the Airbus A380 TTTech developed the internal communication system for the cabin pressure control system, working together with Nord-Micro, a subsidiary of Hamilton Sundstrand Corporation.

Boeing 787

In cooperation with Hamilton Sundstrand Corporation, TTTech developed a TTP-based data communication platform for the electric and environmental control system of the Boeing 787 Dreamliner.

The TTP-designed communication platform prevents an overload in the bus system, even if several important events occur simultaneously. Additionally, TTP-based systems weigh less than conventional systems due to a lower connecter count and less wiring. Furthermore, the whole system is more flexible and has a greater modularity than conventional communication systems.

=Autonomous Vehicles=

DARPA Red Team

The two Red Team robotic vehicles competing in the DARPA Grand Challenge were implemented with "drive-by-wire" technology, in which on-board computers controlled steering, braking and other movements. Three TTP-based TTC 200 units controlled the parking brake and throttle and transmission functions, and one TTP-By-Wire Box controlled the service brake of the H1 Hummer H1ghlander. Drive-by-wire modifications controlled the acceleration, braking and shifting of the Sandstorm.
