Breakthrough in V2X For Driverless Cars Claimed

A GPS positioning specialist is claiming a breakthrough in V2X technology that can position an autonomous vehicle within two centimeters when in underground locations or GPS ‘canyons’.

Racelogic claims successful testing of its VBOX indoor positioning system (VIPS) shows that level of accuracy in measuring speed, position and attitude in areas where GPS is not available. It will be demonstrating the technology at the Bicester Heritage site later this month alongside a Q&A session with the engineers and developers behind the system. The demonstrations will be held inside a large hangar, often used for TV and films, with a live demo of a vehicle being driven by a steering robot following a set course.

The system consists of a network of beacons that are placed around the test area, which communicate with a small receiver mounted on the roof of a vehicle, using Ultra Wideband (UWB). The receiver features an integrated VBOX IMU with Kalman Filter and connects directly to a VBOX 3i data logger, enabling you to capture data from a vehicle’s CAN bus along with position, velocity and attitude angles. The IMU helps reduce noise and dynamic errors in the measurements while the GPS enabled VBOX 3i connectivity ensures a seamless transition between indoor and outdoor environments, providing the complete automotive testing solution in any environment.

The company claims the key to its new system is the ability to conduct dynamic vehicle test and validation procedures using the same test equipment that is been limited to outdoor use. This means testing can be held anywhere with limited or no satellite coverage.
