V2X solution combines Renesas R2 with Cohda Wireless software

October 07, 2016 // By Christoph Hammerschmidt
Chipmaker Renesas has announced a collaboration with Vehicle-to-X software company Cohda Wireless which will result in a V2X reference solution based on Renesas’ R-Car SoC , and Cohda’s software for V2X and connected autonomous vehicles (CAVs). The platform also contains the necessary security module and targets European and North American markets.

In response to the industry expectations for U.S. Department of Transportation (USDOT) to mandate V2X to improve road safety and efficiency in addition to the recent deployment of V2X technology in Japan, targets have been set to widely introduce secure V2X technology in multiple global regions. With over a decade of R&D on IEEE 802.11p protocol, WLAN-based technology has proven to offer reliable and secure communication for Cooperative Intelligent Transport Systems (C-ITS). Critical and time-sensitive information on all road users and roadway elements, such as traffic control devices, are expected to be shared among for improved safety and efficiency. According to USDOT estimates , V2X technology can minimize over 80 percent of non-impaired crash types. 

Renesas now has established an ecosystem with Cohda Wireless to offer a reference solution that will contribute to the acceleration of V2X system development. Cohda Wireless already has a similar cooperation in place with Renesas competitor NXP.

The starter kit, available starting April 2017, complies with European and North America standards from the European Telecommunications Standards Institute (ETSI), Intelligent Transport Systems (ITS), Society of Automotive Engineers (SAE) and IEEE.

The starter kit for the V2X reference solution comprises the R-Car W2R, a 5.9 GHz band automotive wireless communication WAVE SoC, and the V2X host processor R-Car W2H SoC with an embedded hardware security module (HSM), which encrypts the communication/messages and protects against cyber-attacks. The R-Car-based starter kit conforms to the IEEE 802.11p communication standard for ITS used in Europe and North America and to all other applicable standards including that for security requirements. The starter kit also meets or exceeds the SAE minimum performance requirements established for the USDOT-funded connected vehicle pilots, which is widely expected to be the precursor to wider deployment of V2X-enabled infrastructure. The R-Car W2R delivers industry-leading performance when using Renesas' exclusive radio frequency (RF) system design technology, e.g., suppressing out-of-band transmission signal noise below the -65 dBm stipulated by ETSI.
