Vehicle positioning method and assembly, electronic equipment and storage medium

Abstract

The invention provides a vehicle positioning method and assembly, electronic equipment and a storage medium. The method comprises the steps that whether the state of a GPS signal obtained by a vehicle-mounted positioning system is effective or not is judged; if it is determined that the GPS signal state is invalid, the environment state type of the vehicle in an electronic map of the vehicle-mounted positioning system is determined according to a strapdown inertial navigation resolving result in the vehicle-mounted positioning system; corresponding filtering data and filtering parameters are determined according to the environment state type; a strapdown inertial navigation resolving result is corrected according to the filtering data, the filtering parameters and an adaptive Kalman filtering model; and a vehicle positioning result is determined according to a correction result of the strapdown inertial navigation solution. According to the method, the filtering data and the filtering parameters which are most matched with the environment state type are determined by utilizing the environment state type of the vehicle in the electronic map, and then the strapdown inertial navigation calculation result is corrected according to the most matched filtering data and filtering parameters, so that an accurate correction result and a vehicle positioning result can be obtained.

Description

technical field [0001] The embodiments of the present application relate to the technical field of positioning, and in particular, to a vehicle positioning method, component, electronic device, and storage medium. Background technique [0002] With the improvement of living standards, traveling by car has become a daily choice for people. In the process of vehicle driving, in order to provide people with navigation signals or route guidance, vehicle positioning has become an indispensable link. [0003] In the prior art, the global positioning system (Global Positioning System, referred to as GPS) is generally used to locate the vehicle, but when the vehicle is located in a special environment where the satellite signal is blind, there will be an occluding object above the GPS receiver. The problem of signal loss of lock, at this time the transmission of GPS positioning signals will be limited. At this time, the accuracy of vehicle positioning cannot be guaranteed. Conte...
