Under the guidance of AUDI AG, we developed the central platform control unit “zFAS” integrating various functionalities of advanced driver assistance systems (ADAS). The ECU also enables comprehensive fusion of sensor data. Microcontrollers from Infineon Technologies AG safeguard that highest requirements towards computing performance and safety are met.
zFAS addresses the rapidly increasing performance demand of active and passive assistance systems. It enables new functions such as piloted driving on congested highways and piloted parking. Requirements concerning functional safety, connectivity and computing capacity have reached new levels. The demand is driven by functional integration and the fusion of safety critical sensor data. The developers of the multicore processing platform took this specifically into account: an important part of the platform controller is TTTech’s Deterministic Ethernet, a reliable, real-time-capable Ethernet backbone solution. It enables the combination of data traffic of different criticality with a high data throughput. Furthermore, TTTech’s TTIntegration is used as middleware to run the application functions on top of the networked multiple microcontrollers.
In alignment with Audi, TTTech selected AURIX™ TC297T microcontrollers from Infineon for zFAS. The AURIX family offers a broad range of microcontrollers including advanced multi-core products for highest requirements. “We are delighted to provide our high-performance AURIX microcontrollers as the centerpiece for the futureproof platform solution zFAS,” said Thomas Böhm, responsible for Autonomous Driving MCUs at Infineon. “Thus, we are further expanding a fruitful partnership with TTTech”. Infineon’s AURIX TC297T microcontrollers with their lockstep architecture and a special safety management unit can host multiple safety-related functions up to ASIL D.
