Abstract

The present application discloses a method, device and equipment for determining the lane where a vehicle is located, and relates to the technical field of intelligent driving, in particular to the technical field of vehicle positioning. The solution disclosed in this application is as follows: obtain the rough position information of the vehicle at the current moment, and the perception data of the vehicle at the current moment, the perception data includes the information of n perceived lane lines collected by the acquisition device in the vehicle; according to the position information, in the positioning Obtain the information of m+1 real lane lines on the road where the vehicle is located on the map; obtain the confidence that the vehicle is located in m lanes at the current moment according to the information of n perceived lane lines and the information of m+1 real lane lines , and then determine the lane the vehicle is in at the current moment. It can be seen that the present application only needs to obtain sensing data for lane lines, which reduces the requirements for sensing data, and also reduces the difficulty of implementing the solution and the requirements for computing power.

Description

technical field [0001] The present application relates to the technical field of intelligent driving, and in particular to a method, device and equipment for determining the lane in which a vehicle is located. Background technique [0002] In recent years, intelligent driving technology has developed rapidly. In the intelligent driving scenario, when locating the vehicle position, it is necessary to locate the vehicle in a certain lane. And the positioning method based on GPS that usually adopts at present can only obtain the approximate position of the vehicle, and cannot be accurately positioned to the lane level. [0003] At present, when locating the lane where the vehicle is located, the method based on particle filter is usually used. Specifically, the particle filter method is used to fuse the perception data of multiple sensors to directly obtain the precise vehicle position, and then determine the corresponding lane in the map according to the vehicle position. ...
