Safe driving corridor construction method and device, automatic driving vehicle and storage medium

The embodiment of the invention provides a safe driving corridor method and device, an automatic driving vehicle and a storage medium, and relates to the technical field of automatic driving. The method mainly comprises the following steps: acquiring a decision path corresponding to a current position based on the current position of a vehicle; based on the size of the vehicle and the decision path, temporary boundaries on the two sides of the safe driving corridor are determined, the temporary boundaries comprise multiple sets of sub-boundary pairs, and one set of sub-boundary pairs comprise two line segments located on the two sides of the decision path respectively; determining the center of each group of sub-boundary pairs; and constructing a convex polygon based on the center of each group of sub-boundary pairs and the temporary boundary to obtain the safe driving corridor, so that the temporary boundary of the safe driving corridor can be determined according to the size of the vehicle, and the convex p
