‘Game-changing’ V2X radar system launched at World Congress

Australia’s Deputy Prime Minister, Warren Truss, was present when his country’s connected car pioneers launched a game-changing product at the ITS World Congress. With the country hosting the 2016 event in Melbourne, Truss was leading a strong Australian delegation in Bordeaux for the Congress, and was on hand as Cohda Wireless introduced its breakthrough V2X-Radar, which creates immediate value for early adopters of connected vehicle technology. A world leader in V2X technology, which enables connected vehicles to interact with other vehicles (V2V) or with roadside infrastructure (V2I), Cohda’s V2X-Radar delivers low-cost, 360-degree radar for vehicles fitted with V2X connected car systems. The V2X-Radar will offer value for drivers of V2X-equipped vehicles, particularly in the early days when the penetration rate of V2X connected vehicles is low, with a new 360-degree sensor that can detect buildings, road signs and older vehicles, while also being unaffected by rain, snow or fog, and able to work around corners.

The V2X-Radar takes advantage of current V2X systems that use IEEE 802.11 compliant wireless signals to share sensor information between vehicles and infrastructure. These radio signals bounce off many objects, such as walls, road signs and other vehicles, as they travel from transmitter to receiver. Automotive receivers must track this dynamic environment as the vehicle moves. By knowing the position of the transmitter, the receiver and the environment, V2X-Radar can use the radio waves to identify objects within that environment, including non-V2X equipped vehicles. Cohda’s V2X-Radar is a software application that works with standard transmissions from any V2X system, whether it’s on a vehicle or on the roadside. Compatible with both USA and European standards, the V2X-Radar software only needs to be fitted in the receiving vehicle. V2X-Radar can also provide accurate positioning, even in urban canyons, when combined with an onboard 3D map. It can instantly detect vehicle speeds via Doppler measurements and obtain 360-degree sensing from a single antenna. The V2X-Radar will also be an important new sensor component for future autonomous vehicles.

Cohda’s CEO, Dr Paul Gray, said V2X-Radar solved the ‘chicken-or-egg problem’ of delivering value for drivers in the early days when V2X deployment rates are still low. “The challenge of deploying V2X is realizing clear benefits for early adopters,” Gray explained. “We developed V2X-Radar to solve this issue for the V2X business case. V2X-Radar uses standard V2X radio signals to sense the surrounding environment, transforming a standard V2X communications system into a 360-degree car radar. It’s a low-cost addition to a standard V2X system that adds radar functionality to the V2X connected car. “This unique and innovative solution is standards-compliant, requiring no additional hardware in a V2X-equipped vehicle and no additional on-air messages. All it needs is our software in the receiving vehicle. V2X-Radar currently works with the NXP Roadlink chipset.”
