Abstract

The invention provides a vehicle key positioning method and device, and equipment. The vehicle key positioning method comprises the steps: obtaining the vehicle position data at the last moment from the moving track data of a vehicle, and enabling the vehicle position data to serve as the starting point position data of a key; detecting the validity of a satellite positioning system in the key inreal time, and when the satellite positioning system fails, determining and storing the position data of the key at the current moment in a memory according to the movement data collected by a sensormodule in the key at the current moment and the position data of the key at the last moment; when the satellite positioning system is valid, determining the position data of the key at the current moment according to the positioning data acquired by the satellite positioning system at the current moment and the moving data acquired by the sensor module, and storing the position data in the memory;and generating a key track according to the starting point position data of the key and the position data corresponding to the multiple moments, and positioning the key according to the key track. Therefore, when the satellite positioning system fails, the key can be accurately positioned.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to a vehicle key positioning method, device and equipment. Background technique [0002] With the development of technology, people have higher and higher requirements for the positioning of vehicle keys. [0003] In the related art, the vehicle key uses a satellite positioning system such as GPS (Global Positioning System, Global Positioning System) to realize the positioning of the key. However, when there is no GPS signal, the key cannot be located. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0005] For this reason, the first object of the present invention is to propose a vehicle key location method, when the satellite positioning system fails, the movement track of the key is obtained according to the movement data collected by the sensor module, so as to ...
