Autonomous vehicles are currently the major car manufacturers competing in the direction of research, how to ensure that vehicles in extreme weather will not deviate from the road, is the major car makers urgently deal with the problem. It is reported that Sweden has a depot is developing a set of autonomous driving navigation system, navigation through the magnetic force to ensure that the driver will not deviate from driving lanes when driving, to further enhance the safety of future driverless vehicles.
It is reported that this set of magnetic navigation system developed by the Regal car, had been tested in the suburbs of Gothenburg, Sweden. The approximately 100-meter-long carriageway installed in the test car has the same surface as the general road but with a magnet array hidden about 200 millimeters below the road surface.
Magnets are arranged horizontally at a fixed distance. When the test unmanned vehicle drives through the section of road, the magnetic sensor mounted on the vehicle uses the magnet array on the road as a signpost, and signals the computer to correct the waterway , So that the car is like driving along an invisible track, the maximum error of only 10 cm.
