Vehicle Path Generation Method, Vehicle Path Generation Device, Vehicle, and Program
8 Sep 22
A path generation method includes: acquiring information about a position of a vehicle; acquiring information about a target position of the vehicle; acquiring information about a position of an obstacle; setting a constraint condition that the vehicle at each of predicted steps does not interfere with the obstacle, based on the position of the vehicle, a size of the vehicle and the position of the obstacle; and calculating a moving path of the vehicle by optimization calculation based on the constraint condition and an evaluation function in which a score becomes higher as a deviation between the position of the vehicle at each of the predicted steps and the target position becomes smaller.
