Nissan Motor has adopted Renesas’ chips for the ProPILOT 2.0 system featured in the new Nissan Skyline unveiled on July 16. The driver assistance system combines navigated highway driving with hands-off, single-lane driving capabilities, employing Renesas’ R-Car automotive SoC and RH850 automotive control MCU to implement core functionality in the electronic control units (ECUs) that handle driving judgment and control.
Designed for on-ramp to off-ramp (ramp-to-ramp) highway driving, ProPILOT 2.0 engages with the vehicle’s navigation system to help maneuver the car according to a predefined route on designated roadways. For the first time, the system also enables hands-off driving while cruising in a single lane.
To achieve this advanced capability, the Renesas R-Car SoC first creates detailed environment maps of the vehicle surroundings by combining information on nearby vehicles and other objects from the cameras and front radar with the high-precision 3D map data preloaded for navigation. The SoC determines the vehicle’s own position from the map data and lane information and, based on this information, determines the vehicle’s action plan.
The RH850 MCU receives the resulting data and sends control commands to the ECUs such as the steering wheel, accelerator, brakes. Combining the R-Car SoC’s high-performance processing with the RH850’s real-time responsiveness and excellent reliability enables judgment and control operations to take place sequentially and accurately. This contributes substantially to the realization of Nissan’s ProPILOT 2.0 driver assistance system.
