Wireless modules enable Advanced V2X using DSRC or C-V2X

Murata has been cooperating with Autotalks to introduce pioneering new Avanced V2X technology that will facilitate progression towards cooperative safety and higher levels of automated mobility. This has allowed Murata to introduce a wireless module portfolio through which direct vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication can be supported.

For maximum versatility, this V2X product can be adapted to customers’ requirements. It will feature Murata’s Type 2AN wireless module when intended for use in host-less configurations. In situations where there is a built-in host, the Type 1YL will be employed instead. Both these automotive-grade units are based on CRATON2 and SECTON V2X chipsets from Autotalks. As well as being top performing, these modules are highly robust — thereby ensuring ongoing reliability, even in the most challenging of operating conditions. The Murata modules are able to support V2X software stacks from numerous different vendors.

What differentiates the Murata modules using the chipset from Autotalks is the ability of customers being able to choose which of the two V2X communication standards they want to use — DSRC or C-V2X. Consequently, they can directly address different geographic regions (such as Europe, Asia, North America), with the same module, through simple software configuration. This means that systems designs can remain the same, resulting in the associated engineering costs being significantly lower.

Example use cases for this V2X technology include:

Early detection of unseen hazards — here, via V2V, an Electronic Emergency Brake Light alert can notify the driver that a vehicle which is not visible to them at that stage (but will affect them) is applying its brakes.

Traffic prioritization and speed control — through V2I, roadside infrastructure can communicate with vehicles so that their speed is optimized in harmony with traffic signaling routines. This will mean that drivers are not stuck waiting at road intersections, with better traffic flows being maintained and fuel economy optimized (thanks to less acceleration/deceleration).

Other potential use cases include accident response, updates on road conditions, amongst others.

Murata’s V2X modules have already been selected for integration by a major vehicle manufacturer. Car models equipped with these modules are expected to be on the road by early 2024.

“Drawing on Autotalks’ advanced technology, alongside our acknowledged expertise in the wireless domain, this unique platform represents a major step forward in enabling vehicles to cooperate on the road through V2X communication” states Toshifumi Oida, Director of the Communication Module Division at Murata. “The broad array of possible use cases supported will lead to dramatic improvements in road safety and reduce traffic congestion.”

“Inclusion of our hybrid wireless technology means both DSRC and C-V2X can be supported on the same module,” Oida continues. “In addition to offering customers a foundation for their V2X systems through this platform, our highly-trained engineering team can also assist them in relation to antenna design and system optimization.”

“This is a major milestone that draws on over half a decade of joint development, validation, extensive testing and design optimization. In addition, it demonstrates the quality, robustness and performance levels that we can achieve by working together,” states Ram Shallom, VP Business Development & Marketing for APAC at Autotalks.

Shallom concludes; “The versatile V2X module portfolio of Murata will help automotive customers all over the world accelerate V2X commercialization.”
Design fixed versions of the Murata modules can now be sampled, with volume production starting in 2023.
