Collaboration to develop ‘future proof’ ECU platform

Jean-Francois Chouteau, Renesas

Renesas and TTTech are working to develop a future proof, high performance advanced electronic control unit (ECU) platform for driver assistance systems (ADAS). According to the partners, the platform will integrate Renesas’ RH850/P1x MCUs and R-Car SoCs with TTTech’s TTIntegration software to enable complex automotive solutions.

The platform is being developed in the recognition that technologies from different suppliers must be developed in parallel and integrated as smoothly as possible. These different software packages have to share the available resources without interrupting other applications by blocking shared resources.

The collaboration is designed to respond to these challenges, allowing software components to run on different MCUs and SoCs and on one or more ECUs.

Jean-Francois Chouteau, pictured, vp of Renesas’ global ADAS solutions group, said the partnership was intended to help the creation of ‘truly differentiated solutions’.

Alongside TTIntegration, the platform will also take advantage of TTTech’s Deterministic Ethernet technology. TTIntegration runs as middleware between the CPU and the integrated applications, providing applications with the CPU time and memory they need, while separating or abstracting hardware from applications. Strict partitioning is said to ensure that a bug or defect in one application cannot harm any other or cause the ECU to crash.
