Car-to-kerb comms gets developer boost

Electronics giant NEC has released a set of developer tools for car-2-car telemetry technology, with the aim of helping software developers create and integrate support for the short-range vehicle communications protocol into applications and critical systems.

Car-2-car communication involves using wireless data to allow cars to communicate with each other and sensors in the road. For safety purposes the technology would allow a car to detect whether it was approaching a hazard using wireless information from the cars ahead of it and road sensors embedded at the kerb or in the road surface. Safety features in the car such as speed limitation, emergency braking etc could then be engaged to avoid or safely pass the hazard.

It could also improve traffic flow, as shared telemetry data could alert drivers of congestion and slow moving vehicles. When integrated with satellite navigation applications using developer tools like the NEC Car2X SDK, the data would assist in re-routing and avoiding gridlocked areas. Car-2-car technology would also allow the car to potentially access a wireless internet connection while travelling along a road.

Telemetry data could even be used at a scene of an accident, where forensic teams could use telemetry data from the accident location to digitally reconstruct the events leading up to the incident.

"In-car applications are not our core business." Dr Heinrich Stüttgen, vice president of NEC's European laboratories said. "So what we decided to do instead of waiting for a product to be ready was to allow those people who were building in-car communications applications to experiment with the technology. I think other people in the industry are doing it and it's a way of attracting future users."

Yesterday NEC showcased its work in car-2-car and car-2-roadside sensor technology at its R&D centre in Heidelberg, Germany. IT PRO was shown a demonstration of the technology, which involved the integration of wireless sensor networks between cars and the road surface.
