Toyota Motor Corporation is collaborating with Renesas Electronics Corporation, a supplier of advanced semiconductor solutions, to bring its autonomous vehicles to markets faster, according to Renesas.

Toyota’s autonomous vehicles are currently under development and scheduled for commercial launch in 2020. Renesas will supply its autonomous-driving vehicle solution for integration into Toyota’s self-driving vehicles.

Toyota selected Renesas as the key semiconductor supplier for its “Highway Teammate”, an autonomous-driving prototype car designed to merge, pass, change lanes, and perform other actions during highway driving, under supervision.

Renesas’ autonomous-driving vehicle solution for Toyota’s autonomous vehicles combines the R-Car system-on-chip (SoC), which serves as an electronic brain for in-vehicle infotainment and advanced driver-assistance systems (ADAS), and the RH850 microcontroller (MCU) for automotive control.

The R-Car SoC has been selected for Denso’s engine control unit (ECU), which will be used for Toyota’s upcoming autonomous-driving vehicles. The R-Car SoC provide highly accurate intelligence on the vehicle’s position within its environment and making real-time decisions on vehicle control and active safety maneuvers based on sensor data.

The RH850 was also selected to control driving, steering, and braking functions based on the judgments made by the R-Car SoC. The combination provides a balance between performance and power consumption, and serves as a comprehensive autonomous-driving solution with high reliability, which had a decisive influence on the adoption by Toyota, said Renesas.

 “We are partnering with Denso and Renesas, who bring superior technology and expertise to this project, with the aim to accelerate the development of autonomous-driving vehicles and encourage early adoption,” said Ken Koibuchi, Executive General Manager at Toyota Motor Corporation.
