Challenge

Cohda Wireless’ V2X vehicle warning systems are dependent on highly accurate position and velocity data to deliver the performance that is crucial to meet the safety demands of next generation cars.

Global positioning technology

u‑blox provided key global positioning technology to Cohda Wireless’ Vehicle‑to‑Vehicle (V2V) and Vehicle‑to‑Infrastructure (V2I) equipment, collectively called “V2X”. Cohda’s DSRC (Dedicated Short‑Range Communications) based V2X system uses accurate satellite positioning with embedded dead reckoning technology provided by u‑blox to enhance driver safety through ample warning time and excellent non‑line‑of‑sight performance. The system enables, for example, early warning of an imminent collision, oncoming traffic, presence of road workers and unsafe speed based on vehicles in the vicinity. V2X will be a key technology for the next generation of Advanced Driver Assistance Systems (ADAS) as well as autonomous vehicles.

“Our V2X vehicle warning systems are dependent on highly accurate position and velocity data to deliver the performance that is crucial to meet the safety demands of next generation cars,” said Fabien Cure, Chief Engineer. “u‑blox’ satellite positioning solutions, leading automotive dead reckoning technology, module roadmap and clear strategy to deliver lane accurate performance in  challenging urban environments was convincing. u‑blox’ M8 GNSS technology is the right choice for MK5 and the future Cohda development platform.” Offering best in class performance, the MK5 is suitable for first‑mount automotive electronics, aftermarket products, and roadside infrastructure.
