SoCs prepare for autonomous driving for V2V and V2I
Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication systems will be the backbone for autonomous driving. Renesas Electronics announces two SoCs designed to develop V2V and V2I systems.
One includes the R-Car W1R 760MHz band wireless SoC for the Japanese market, and the R-Car W2H SoC that features a security engine. The other consists of the W2H SoC combined with the R-Car W2R 5.9GHz band wireless communication SoC developed for U.S. and European markets.
By combining these new SoCs, system developers can now easily develop systems that support the corresponding V2X standard for the Japanese, U.S., and European markets, says the company. Development starter kits enable system developers to immediately start application software development, to reduce the development period for V2X systems.
The R-Car W1R conforms to Japan’s wireless communications standards, and is adopted in the ITS Connect V2V and V2I communications system. It was adopted in Denso Corporation’s in-vehicle ITS units used in Toyota’s Crown, Prius, and Lexus RX models for displaying traffic signal violation, cross traffic, and pedestrian warnings at traffic signals using car and infrastructure communications to warn drivers about approaching emergency vehicles and to assist cruise control and other functions.
Differing communication frequencies, communication standards, and security standards in Japan, the US and Europe, create challenges for optimising devices for each region and the associated software development for V2X system development. V2X kits from the company combine either the R-Car W1R or R-Car W2R with the R-Car W2H.
Samples of the SoCs are available now.
