  • Patent number: 11433899
    Abstract: Provided are a method, apparatus and system for detecting obstacle collision in an automatic parking path. The method includes: geometrically performing an obstacle collision detection in a circular arc path and/or an obstacle collision detection in a straight line path by using a path contour, a vehicle contour and an obstacle contour. The system includes a collision detection module for geometrically performing detection of obstacle collision in a circular arc path and/or detection of obstacle collision in a straight line path by using a path contour, a vehicle contour and an obstacle contour. The apparatus includes: a memory and a processor configured for geometrically performing detection of obstacle collision in a circular arc path and/or detection of obstacle collision in a straight line path by using a path contour, a vehicle contour and an obstacle contour.
