Embodiment Construction
[0034] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.
[0035] In view of the fact that current self-driving cars rely on vehicle positioning, if the vehicle is in a situation where satellite positioning signals are susceptible to interference, there may be a safety problem in automatic driving caused by positioning errors. The invention provides a positioning method and system for a self-driving car. By collecting traffic environment information around the vehicle and calculating the theoretical positioning coordinates of the vehicle through high-precision maps, the theoretical positioning coordinates of the vehicle are then compared with the satellite positioning coordinates. If the deviation is greater than the set threshold , the positioning data is corrected. It...
