Abstract

The invention relates to a path detection method and device and an automobile. The path detection method comprises the steps: acquiring a planned path and boundary conditions of the planned path, wherein the planned path uses a center line of a target reference lane as a reference line; and comparing the boundary condition of the planned path with a detection trigger threshold, and determining that the planned path does not exceed the path limit according to the condition that the boundary condition of the planned path does not meet the detection trigger threshold. According to the scheme, rapid detection and screening of the planned path can be realized, and the real-time requirement of automatic driving is met.

Description

technical field [0001] The present application relates to the technical field of automatic driving, in particular to a path detection method, device and automobile. Background technique [0002] At present, the technology of automobile autonomous driving is constantly developing. Among them, automatic driving includes automatic lane change function. For the automatic lane change function, it is necessary to detect whether the planned transition path is within the range allowed by the lane line, and it is required not to cross the center line of the target lane too far, that is, to detect whether there is a convex hull in the transition path. [0003] The path detection methods in the related art all need to sample on the planned path, and then analyze the relative relationship between the sampling point and the path limit. However, the method of the related technology has a large amount of calculation and a slow detection speed, which cannot meet the real-time requirements...
