Honda again looks to Renesas for ADAS chips

Honda has again used Renesas Electronics semiconductors for the advanced driver-assistance systems (ADAS) in the latest Legend.

The automaker originally adopted Renesas’ R-Car automotive system on a chip (SoC) and RH850 automotive MCU for its Sensing Elite system in the Legend which went on sale in March 2021. Sensing Elite incorporates advanced technology that qualifies for Level 3 automated driving (conditional automated driving in limited areas).

Now Honda has again selected R-Car and RH850 for use in the Sensing 360 omnidirectional safety and driver assistance system which builds on the knowledge and expertise gained through research and development work on the earlier technology.

The first car with Sensing 360 is scheduled for release in China in 2022 with adoption in a broader range of models to follow.

For the next generation system, Honda chose the R-Car S4 as the main SoC in the electronic control unit (ECU), the core of the ADAS.

“Takeshi Kataoka, general manager of Renesas’ automotive solution business unit said: “We plan to further expand our collaboration to bring sophisticated driver-assistance systems to all mass-production models in the near future.”

The R-Car automotive SoC processes sensing data from cameras, millimetre wave radar, and LiDAR as well as data for 3D high definition maps and the global navigation satellite system (GNSS). It also monitors the vehicle’s position and the road conditions, and computes route plans in real time. The RH850 MCU provides support for driving operations and collision avoidance by receiving signals from R-Car and performing advanced control of the accelerator, braking, and steering systems.
