Prototype ECU targets automated driving systems

Article By : Renesas Electronics

The highly automated driving platform has been developed based on an ASIL-D functional safety concept.

Renesas Electronics and TTTech Computertechnik have rolled out a highly automated driving platform (HADP), which is a prototype electronic control unit (ECU) for mass production vehicles with integrated software and tools. The HADP accelerates the path to mass production for Tier 1s and OEMs, according to the companies.

The newly released HADP is the first outcome of the collaboration between TTTech and Renesas announced in January 2016, and is an extended version of the HAD solution kit released in October 2016. It is based on dual R-Car H3 system-on-chips (SoCs) and the RH850/P1H-C microcontroller.

The HADP has been developed based on an ASIL-D functional safety concept. It supports a highly efficient integration process for complex highly automated driving systems. It shortens time to market by enabling system developers to verify and integrate software easily on the prototype ECU designed to deliver a faster track to mass production vehicles.

The ECU has been developed for automotive sample grade quality following requirements on thermal design and shock resistance. It is provided in an aluminium housing targeting IP51 protection level for mounting in the passenger cabin or luggage compartment. The HADP can be directly connected to an automotive power supply and is designed to work at -40 to 85°C operation temperature and exposed to vibrations in a running vehicle. The HADP comes with cabling and guidelines for easy adaption inside a vehicle.

Due to a co-simulation environment on a standard PC it is possible to develop functions on the embedded HADP platform side-by-side with applications running on a PC. They all can share the same data and services as if it would be a single domain ECU.

The HADP and development support are scheduled to be available in Q2 2017 by TTTech.
