NXP Semiconductors has developed V2X-enabled prototypes including a smart V2X-enabled e-bike together with bicycle manufacturer Riese & Müller. NXP’s V2X technology is based on 802.11p, also known as DSRC (Dedicated Short-Range Communication), which is designed to allow vehicles, road infrastructure and other road users to exchange information in real time.

As a demonstrator to how road safety can be improved through adoption of V2X technologies, NXP and Riese & Müller have built a smart electric bicycle prototype. The demonstration combines NXP’s RoadLINK automotive-qualified DSRC modem and Hardware Secure Element IC for V2X applications, with the Cohda Wireless’ On–Board Unit. The configuration enables the e-bike to transmit data on its position, speed and direction of travel to other V2X-enabled vehicles in the vicinity that could pose a potential danger to the cyclist. The module calculates the distances between road users and position changes within seconds. In the event of a dangerous situation, both the cyclist and a car’s driver, would receive a timely collision warning.

“Everyone on the road deserves to be safe, from the student on a bike to the road worker and those in premium vehicles. The quest starts with allowing vehicles and road users to communicate in real time and V2X meets this need by linking infrastructure and road users,” said Huanyu Gu, Senior Product Marketing Manager ADAS at NXP. “V2X can connect and inform a vast web of e-bikes, e-scooters, breakdown assist vehicles and even construction site lighting to create a web of safety for all who share the roads.”

NXP has also launched a new application processor to provide secure V2X connectivity. The i.MX 8XLite applications processor is capable of simultaneously handling complex cryptography and telematics data.

The company is also working with Ford of Europe, Kopernikus, Continental, and Cohda Wireless on how V2X technology can be deployed to enable secure automated valet parking.

NXP’s V2X technology has also been used to develop BiDiMoVe (Bidirectional multimodal network), a demand-based prioritisation of public traffic at traffic lights including new hazard warning system, and also Green4transPORT, a dynamic traffic management including intelligent traffic lights control.
