Automated driving platform

Prototype ECU for mass production

Renesas and TTTech provide together the highly automated driving platform (HADP) electronic control unit (ECU). It is based on the dual R-Car H3 system-on-chips (SoCs) and the RH850/P1H-C micro-controller.

The platform ECU comes with integrated software and tools, which demonstrate how to use Renesas and TTTech technologies combined in an automotive environment for autonomous driving. The HADP accelerates the path to mass production for Tier 1s and OEMs. It provides four CAN FD, two Classical CAN, two Flexray, two LIN, and four Ethernet (BoradR-Reach) interfaces for in-vehicle networking purposes. For debugging and development purposes, there are additionally one deterministic Ethernet, three UART, two USB, two HDMI, and two M.2 ports.

The automotive market is moving rapidly to make autonomous driving a reality for consumers by 2020. The increasing information from sensors as well as its assessment and resulting actions require hardware and implementations of software that have enough performance and comply with safety standards. Furthermore, the range of sensors and functions means new challenges for the implementation and integration of software. The 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 micro-controller.

The HADP has been developed based on an ASIL-D functional safety concept. It supports an integration process for automated driving systems. The HADP can be used by Tier 1s and OEMs to immediately prototype their functions in an embedded automotive ECU. According to the suppliers it shortens time to market by enabling system developers to verify and integrate software on the prototype ECU designed to deliver a faster track to mass production vehicles.

“With the automotive industry's increasing focus on autonomous driving, OEMs are set to play a key role in ensuring the safety and robustness of innovative functions,” said Jean-Francois Chouteau, Vice President of Renesas’ Global ADAS Centre. “The HADP offered by TTTech and Renesas enables OEMs to drastically reduce both development efforts and the time needed to bring autonomous driving on the road.”

“We are delighted to present the first joint platform of the cooperation between Renesas and TTTech,” said Dr. Stefan Poledna, Member of the Executive Board at TTTech. “Renesas’ expertise as a leading semiconductor solution supplier and TTTech’s proven experience as a provider of scalable safety ECU platforms are a perfect match enabling customers to develop highly performance autonomous driving solutions much quicker.”

The ECU has been developed for automotive sample grade quality following requirements on thermal design and shock resistance. It is provided in an aluminum 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 °C to +85 °C operation temperature and exposed to vibrations in a running vehicle. The HADP comes with cabling and guidelines.

The TTIntegration software coming with the HADP provides all the services to run several safety critical applications in parallel on multiple SoCs. The partitioning concept ensures that safety-related applications cannot be impacted by other applications running at the same time. Due to a co-simulation environment on 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. According to the suppliers the integration and testing of all applications are remarkably faster and more efficient in comparison to the usual step-by-step solutions.
