Abstract

The invention relates to a method and a device for analyzing obstacle of a vehicle, and relates to the technical field of control technology, wherein the method comprises: rasterizing environmental information data so as to acquire a first grid map, expanding the first grid map according to the size of the vehicle, acquiring a second grid map, determining whether there is a path grid overlapping with the obstacle grid in the second grid map, the path grid is at least one grid in the second grid map corresponding to all the path points in the preset path, the size of the path grid is the same as that of the vehicle, when there is a path grid overlapping with a barrier grid in the second grid map, whether there is a collision point in the path is determined according to the first grid map and the path grid. The accuracy and the efficiency of the path obstacle analysis can be improved; meanwhile, the calculation amount and the requirements of the hardware are reduced.

Description

technical field [0001] The present disclosure relates to the technical field of control, and in particular, relates to a vehicle obstacle analysis method and device. Background technique [0002] With the continuous increase of the number of cars in our country and the continuous development of electronic control technology, people have more and more opportunities to use the automatic driving state of cars in their daily lives. The automatic driving function can plan the global path of the vehicle in advance according to the user's needs and map information, and then analyze the obstacles according to the surrounding environment of the vehicle body, so as to adjust the local path of the vehicle in real time. When performing obstacle analysis, it is necessary to convert the actual map information into a grid map, and then judge whether there is a collision point according to the path points and the grid map in the local global path. Among them, the size of the grid in the gr...
