As a result, and based on this cooperation, Murata has introduced a wireless module solution portfolio through which direct vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication can be supported and that can be adapted to customers’ requirements.
The portfolio features 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 Autotalks’ CRATON2 and SECTON V2X chipsets.
According to Murata, these modules are highly robust, ensuring ongoing reliability, even in the most challenging of operating conditions. They are able to support V2X software stacks from numerous different vendors.
Importantly, customers will be 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 (Europe, Asia, North America, etc.), 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.
Use cases for this V2X technology could 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 prioritisation and speed control - Through V2I, roadside infrastructure can communicate with vehicles so that their speed is optimized in harmony with traffic signalling 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 and updates on road conditions.
Murata’s V2X modules have already been selected for integration by a major vehicle manufacturer and car models equipped with these modules are expected to be on the road by early 2024.
“Drawing on Autotalks’ advanced technology, this platform represents a major step forward in enabling vehicles to cooperate on the road through V2X communication,” said 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 continued. “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 solution optimisation.”
“This is a major milestone that draws on over half a decade of joint development, validation, extensive testing and design optimisation. In addition, it demonstrates the quality, robustness and performance levels that we can achieve by working together,” added Ram Shallom, VP Business Development & Marketing for APAC at Autotalks.
Design fixed versions of the Murata modules can now be sampled, with volume production starting in 2023.
