Infineon and TTTech to Accelerate Autonomous Driving Development

Under Audi’s supervision, TTTech has recently developed the central platform control unit “zFAS” incorporating different functionalities of advanced driver assistance systems (ADAS). The ECU also allows complete fusion of sensor data. Meanwhile, microcontrollers from Infineon Technologies ensure that highest requirements towards computing safety and performance are met.

zFAS deals with the quickly increasing performance demand of active and passive assistance systems by enabling new functions such as piloted driving on cramped highways and piloted parking. This demand is driven by functional integration and the combination of safety critical sensor data. Taking this into account, the developers of the multicore processing platform developed TTTech’s Deterministic Ethernet, a highly reliable, real-time-capable Ethernet backbone solution. It allows the fusion of data traffic of various criticalities with a high data throughput. Moreover, TTTech’s TTIntegration is utilized as middleware to run the application functions on top of the networked multiple microcontrollers.

TTTech chose AURIX™ TC297T microcontrollers from Infineon for zFAS to align with Audi. The AURIX family features a wide range of microcontrollers, including innovative multicore products for highest requirements.

In a statement, Thomas Boehm, responsible for Autonomous Driving MCUs at Infineon, said that they are thrilled to offer their high-performance AURIX microcontrollers as the centerpiece for the future-proof platform solution zFAS. “Thus, we are further expanding a fruitful partnership with TTTech.” Infineon’s advanced AURIX TC297T microcontrollers, featuring a special safety management unit and lockstep architecture, can host a number of safety-related functions up to ASIL D.

According to Marc Lang, Director Sales & Marketing at TTTech Automotive, zFAS marks a milestone for highly integrated platform control units for advanced driver assistance. He noted that Infineon’s state-of-the-art microcontrollers and TTTech’s real-time Ethernet solutions are core components for this innovative ADAS solution.

Moreover, based on Deterministic Ethernet and Infineon’s AURIX TC297T, TTTech has come up with an assessment platform for driver assistance system ECUs, called TTA Drive. It is designed to quickly and easily integrate various application modules at an early stage of series development. This process of integration is supported by a software called TTIntegration and a tool-set particularly developed for TTA Drive.

In the scope of a capital increase in March last year, Infineon purchased a stake in TTTech which specializes in highly reliable, networked and safety-relevant control systems in vehicles.
