Renesas Electronics Corporation today announced the global availability of its expansive lineup of V2X solutions that will help accelerate the arrival of autonomous driving.
The solutions include two system-on-chips(SoC) that will ease the development process for vehicle-to-vehicle(V2V) and vehicle-to-infrastructure(V2I) communication systems.
One of the solutions includes the R-Car W1R 760MHz band wireless SoC for the Japanese market, and the new R-Car W2H SoC that features a high-performance security engine that is indispensable for V2X systems designed for the Japanese, U.S., and European markets.
The other solution 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.
Renesas also delivers development starter kits that will enable system developers to immediately start application software development, leading to significant reductions in the development period for V2X systems.
In October 2015, Renesas launched the R-Car W1R, which conforms to Japan's wireless communications standards, and is adopted in the ITS Connect1 V2V and V2I communications system.
It is the only device in the world with a proven track record that is currently commercially deployed in the V2X wireless SoC market. The R-Car W1R was adopted in Denso Corporation's in-vehicle ITS units.
These units are also 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.
In addition to the current V2X activities led by Japan, steady progress is being made in U.S. and European investment plans due to legislation and implementation of V2X technology.
At the same time, the countries’ differing communication frequencies, communication standards, and security standards have made optimizing devices for each region and the associated software development into significant challenges for V2X system development.
To ease these burdens, Renesas delivers V2X kit solutions that combine either the R-Car W1R or R-Car W2R with the R-Car W2H. These kit solutions make it possible to construct optimal systems for each region at low cost.
