VEHICLE POSITIONING METHOD AND APPARATUS, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/189464
Kind Code:
A1
Abstract:
A vehicle positioning apparatus (104) and method, a computer program product and a vehicle. By means of detecting received signal strength of signals transmitted by road communication devices (101, 102, 103) that are fixedly arranged on the roadside on which a vehicle is traveling, the distances between the vehicle and at least three road communication devices (101, 102, 103) are determined on the basis of the received signal strength. The coordinates of the vehicle are determined according to the coordinates of the road communication devices (101, 102, 103) and the calculated distances. Since there is no barrier obstruction between the vehicle and the road communication devices (101, 102, 103) and the received signal strength is relatively large, the problem of positioning offset caused by the use of satellite positioning in the prior art is solved. Therefore, the positioning accuracy of the vehicle may be improved.
