ProPILOT 2.0 is a driver assistance system that combines navigated highway driving with hands-off, single-lane driving capabilities.
Renesas Electronics Corporation announced today that Nissan Motor Co Ltd has adopted its R-Car automotive system-on-chip (SoC) and RH850 automotive control microcontroller (MCU) for ProPILOT 2.0 featured in the newly-unveiled Skyline car. ProPILOT 2.0 driver assistance system makes use of Renesas R-Car SoC and RH850 MCU in the process of implementing core functionality in the electronic control units (ECUs) that handle driving judgment and control.
The ProPILOT 2.0 system has been designed to enable on-ramp to off-ramp (ramp-to-ramp) highway driving by engaging with the vehicle’s navigation system to help manoeuvre the car across a predefined route on designated roadways. As a first-time feature, the driver assistance system also enables hands-off driving while cruising in a single lane, explained Renesas.
The Renesas R-Car SoC first creates detailed environment maps of the vehicle’s surroundings by combining information on nearby vehicles and other objects, in order to achieve these advanced capabilities. The environment maps are created through data collected from cameras and front radar with high-precision 3D map data preloaded for navigation. Renesas explained that 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.
Meanwhile, the RH850 MCU receives the resulting data and sends control commands to the ECUs, which include those present in the steering wheel, accelerator and brakes. Combining the R-Car SoC’s processing with the RH850’s real-time responsiveness enables judgment and control operations to take place sequentially and accurately, the company noted. It said that this contributes substantially to the realisation of Nissan’s ProPILOT 2.0 driver assistance system.
Shingo Yamamoto, Executive Vice-President, General Manager, Automotive Solution Business Unit, Renesas, said the company is honoured that Nissan has adopted the company’s automotive semiconductors in the ProPILOT 2.0 system featured on the new Skyline. “Nissan’s confidence in the processing performance and quality of our semiconductors and in Renesas as a partner in the overall project of advanced driver assistance system ECUs made it possible to combine our technological expertise for development. I look forward to seeing our relationship with Nissan to grow even stronger,” he added.
Realising ProPILOT 2.0 on the Skyline required the technological innovation of achieving performance that can handle high volume of real-time sensor data processing, noted Takashi Yoshizawa, Vice-President, Alliance Global Director, EE and Systems Engineering Division, Nissan Motor. He said that numerous years of collaboration with partners such as Renesas have enabled Nissan to drive technological advances leading to the realisation of advanced driver assistance technology.
