Renesas Electronics, a premier supplier of advanced semiconductor solutions, announced that Nissan Motor, has adopted Renesas’ innovative and high-peformance automotive technology for the ProPILOT 2.0 system featured in the new Nissan Skyline unveiled on July 16, 2019. 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 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.
“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 Div., Nissan Motor Co. “Many years of collaboration with partners such as Renesas have enabled Nissan to drive technological advances to the realization of advanced driver assistance technology, and I am delighted that the industry ProPILOT 2.0 has emerged as a result of this work.”
“We are honored that Nissan has adopted Renesas automotive semiconductors in the ProPILOT 2.0 system featured on the new Skyline,” said Shingo Yamamoto, Executive Vice President, General Manager of Automotive Solution Business Unit, Renesas Electronics. “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.”
Renesas will continue to supply innovative solutions that help spur the development of driver assistance systems and autonomous driving technology, contributing to the emergence of reliable and safe mobility options.
