Australian technology firm, Cohda Wireless, has shown its new 360-degree radar system, to become an integral part of driverless cars of the future.
Unlike traditional sensor systems, Cohda’s new system is unaffected by rain snow or fog, and has the ability to ‘see’ around corners.
Using V2X technology (vehicle to everything) connected cars are able to communicate with V2V (vehicle to vehicle) equipped vehicles, and V2I (vehicle to infrastructure) to share information about road and traffic conditions.
Cohda’s 360-degree V2X-Radar is also able to detect road signs, buildings and older vehicles that lack V2V capabilities.
During this week’s International Driverless Car Conference, to be held in Adelaide, Cohda Wireless will be offering demonstration rides in a V2X-Radar equipped vehicle.
Cohda Wireless CEO Dr Paul Gray describes V2X-Radar as a ‘disruptive technology’. “It’s a low-cost addition to a standard V2X system that adds radar functionality to the V2X connected car,” he said.
“V2X systems are essential for driverless cars, extending their view of the world beyond that of traditional sensors. V2X-Radar pushes this even further, allowing driverless cars to sense the environment in ways not previously imagined.”
Cohda’s V2X-Radar operates on the existing V2X signal system to share information between vehicles and infrastructure. The radio signals used bounce off building, road signs and other vehicles, and V2X-Radar is able to use these signals as a way of identifying nearby objects.
Combined with 3D mapping, V2X-Radar is able to provide highly accurate positioning, can instantly detect vehicle speeds via Doppler measurements, and is able to obtain 360-degree sensing from a single antenna.
Dr Gray described V2X-Radar as solving the ‘chicken-or-egg problem’ for early adopters of V2X equipped vehicles, by providing a solution that works even without high numbers of connected cars on the roads.
