  • Publication number: 20230303120
    Abstract: The present disclosure provides a method and system for obstacle-avoidance in a self-driving, a system, and a storage medium, comprises: obtaining information of the obstacles, the information including sets of coordinates of the obstacles; determining a feasible area according to the information; determining a waypoint according to the feasible area, and determining an attractive force of the waypoint according to the waypoint and a preset attractive potential field function; determining a repulsive force of the obstacles according to the coordinates of the obstacles on sides of the feasible area and a preset repulsive potential field function; and determining a total force according to the attractive force and the repulsive force, and a steering command issued accordingly. A defect of Artificial Potential Field deflecting into the local minimum, and problems of environmental constraints and the constraints of the vehicle itself in a structured urban environment are resolved.

  • Publication number: 20210080267
    Abstract: Provided are a path planning method and device for an unmanned vehicle, road segments of an origin and destination of a path are acquired; path search is performed to generate an initial path according to an exit endpoint of the road segment where the origin is located, an entrance endpoint of the road segment where the destination is located, and entrance endpoints and exit endpoints of the road segments for connecting the exit endpoint of the road, segment where the origin is located to the entrance endpoint of the road segment where the destination is located; an exit endpoint of a previous road section of the connecting passages in a passable direction is updated according to entrance endpoints of the connecting passages in the initial path; and a final planed path is generated according to different endpoints in the updated initial path.
