TTTech’s contribution to this system is a scalable ECU platform that combines a flexible architecture and safety kit that can be adapted to the needs of customers like Audi – but since it is available to automotive OEMS and suppliers, also other carmakers can be expected to put the platform into the center of their car’s electronic guts. TTTech has already developed a similar platform based on Renesas microprocessors, and eeNews Europe learned that Asian carmakers are taking closer looks to the system.
The various multicore processors in the zFAS (Mobileye for image processing, Nvidia for sensor fusion number crunching, Intel FPGA for miscellaneous tasks, and Infineon’s Aurix for steering and braking) are tied together through a safe deterministic Ethernet connection. TTTech’s software provides a complete runtime and development environment and complies to the highest safety level (ISO 26262 ASIL D). TTTech holds the responsibilities for ECU safety from prototyping, production of A and B samples and series production and ECU flashing, explains TTTech member of the executive board Stefan Poledna. “Our environment supports Autosar as well as alternative operating systems such as Wind River or Linux derivates”, Poledna said. Likewise, it is closely entangled with development tools like those from Vector Informatik and other third parties, Poledna assured.
