Architecture for System 3 & 4 automated driving

Update: October 22, 2021

This enables processing of, for example, radar or LiDAR camera sensor data and is targeting car and technology manufacturers.

The fail-operational architectural concept and its key components ensure the safe operation of highway pilot functions, valet parking and autonomous truck driving in case individual functions fail.

The joint research contributed to the European PRYSTINE (Programmable Systems for Intelligence in Automobiles) project.

With a budget of about € 50 million, PRYSTINE aimed to realize safe automated driving by fail-operational urban surround perception.

For three years, about 60 partners worked together in the areas of sensor-fusion, electronic architectures and artificial intelligence coordinated by Infineon

A  failover mechanism consisting of a primary (“Doer” node) and a fallback ECU (“Fallback” node) ensures the necessary fail-operationality for vehicles.

In case the “Doer” fails, the “Fallback” promptly takes over within the millisecond range.

This mechanism ensures the fail operationality of the system, for example, sensor fusion, trajectory planning and object recognition tasks of SAE Level 3 and 4 functions.

The modular concept offers the flexible  development of Automated Driving Systems (ADS) by enabling the combination of various off-the-shelf elements such as SoCs (System on a Chip), automotive microcontrollers, power supplies, with the deterministic backbone network as well as multiple cameras.
