At the CES in Las Vegas, Audi and its technology partner TTTech Computertechnik AG presented a prototype of the zFAS platform ECU for piloted driving. TTTEch is a leading provider of reliable network solutions based on time-triggered technology and modular safety platforms. (Earlier post.)

The highly integrated platform ECU zFAS is based on a complex multicore network, hosting sophisticated sensor fusion and a variety of innovative functions with multiple safety criticality levels for applications such as piloted parking or driving.

Our goal is leadership in piloted parking and piloted driving. For this purpose TTTech and Audi are developing a highly advanced high performance central electronic control unit. It will feature performance and computing capacity superior to the entire electronic architecture of today’s Audi A4. With this high performance system we are entering the path towards piloted parking and driving in an entirely connected world.

Audi and TTTech Group have been cooperating very closely in the field of time-triggered systems since 2001. One major result of this cooperation is the introduction of FlexRay in the Audi A8 to optimize its data communication.

Audi also is a development partner of TTTech for the TTXDataLogger, a high-performance, open and scalable data logger. Audi utilizes the device for date recording and fault analysis during automobile testing.

TTTech has already introduced the networking technology Deterministic Ethernet (TTEthernet); a fully location transparent and observable middleware (TTIntegration); and its multi-criticality safety platform (TTSafety) with market leaders in the aerospace, space and industrial markets.

TTEthernet was designed for safe and highly available real-time applications, cyber-physical systems and unified networking. The technology offers deterministic real-time communication and TCP/IP Ethernet traffic in parallel on the same network, and simplifies the design of fault-tolerant and high availability solutions.

The next NASA spacecraft, the ORION Multi-Purpose Crew-Vehicle (MPCV), deploys TTTech’s TTEthernet technology as the core network for its avionics systems.

Most recently, TTTech has started to work with Cisco to establish Deterministic Ethernet as an enabling technology for the real-time Internet of Things (IoT).

These activities have helped to establish an eco-system of semiconductor and software suppliers consisting of Altera, Infineon Technologies, NVIDIA, NXP, Texas Instruments, Vector Informatik, Wind River and Xilinx, which are supporting and contributing key elements to TTTech’s networked computer platforms.

We are proud to leap forward with our cross-industry-proven core technology components towards Audi’s vision of piloted driving.
