Renesas Electronics said Nissan Motor was using its chips for the ProPILOT 2.0 system in the new Skyline unveiled on 16 July.
The driver assistance system combines navigated highway driving with hands-off, single-lane driving capabilities, employing Renesas' R-Car automotive system-on-chip (SoC) and RH850 automotive control microcontroller (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 manoeuvre 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.
The 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 reliability enables judgment and control operations to take place sequentially and accurately.

"Realizing ProPILOT 2.0 on the Skyline required the technological innovation of achieving performance that can handle real-time processing of several times more sensor data than ever before while maintaining reliability," said Takashi Yoshizawa, VP, Alliance global director, EE and systems engineering , Nissan Motor.
"We are honoured that Nissan has adopted Renesas automotive semiconductors," said Shingo Yamamoto, general manager of automotive solution business unit, Renesas.
