Patent attributes
A parking assistance device for resetting a parking path when an obstacle is on the parking path includes a pull-out path computing unit that computes a pull-out path for pulling the vehicle out of the parking space based on parking space information and constraints regarding vehicle behavior, a candidate connection position setting unit that sets a plurality of candidate connection positions on the pull-out path, a reachable path computing unit that computes a reachable path for allowing the vehicle to reach at least one of the candidate connection positions from the initial position, a parking path setting unit that sets a parking path of from the initial position to the parking space by connecting the pull-out and reachable paths, and a path resetting unit that computes a parking path of from the stop position to the parking space, and sets the computed parking path as a new parking path.
