The HPC is an automotive computing platform that will be developed to provide centralized control of vehicle systems. It will be equipped with secure gateway functionality for cloud service connectivity.

R-Car M3 supports over-the-air (OTA) software updates with the highest level of security and functional safety. This security makes the central control of automotive software updates possible.

“Thanks to the new server architecture, vehicles will be kept up to date easier and faster than today. We are making the vehicle an integral part of the Internet of Everything, contributing to the higher functionality and comfort in the vehicle,” said Johann Hiebl, head of the Connected Car Networking business unit at Continental. “The first generation of Continental’s Body High-Performance Computer using the high-performance R-Car SoC is already going into production at a global vehicle manufacturer.”

Modern vehicles have to be be able to quickly update software in the field for continued safe operation. Being able to perform software updates individually on the dozens of electronic control units (ECUs) found in a typical vehicle is very hard. A new E/E architecture that uses a central vehicle computer to control software updates will address that challenge.

The R-Car range is scalable, which makes it able to fit that function for a variety of vehicles and the range was has been designed as a general automotive computing platform. In addition to the R-Car M3, which delivers 30,000 DMIPS performance, the Renesas R-Car family ranges from high-end devices such as the R-Car H3, which is built around eight 64-bit Arm CPU cores and 45,000 DMIPS, to the R-Car E3 with 7,500 DMIPS performance.

The R-Car’s virtualization functionality allows the software connecting to external cloud services and the software that controls the vehicle to be isolated. The separation on a single chip allows the R-Car to act as a safe and secure vehicle gateway. R-Car devices also provide hardware security features, such as secure boot and secure network communication via Ethernet to domain controller. They also integrate high-speed Gigabit Ethernet which gives the data throughput needed for fast software updates and the increasing amount of sensor information to support ADAS functions.

R-Car processors can be combined with Renesas’ RH850/U2A cross-domain MCU, which supports up to ASIL D functional safety, and the company’s portfolio of automotive power management and timing solutions for a full solution for vehicle servers.
