Abstract: A vehicle parking control device has a processor and a memory to control the vehicle from a starting to a target parking position. The vehicle control device includes an obstacle detection unit detecting obstacles around the vehicle, a travelable area setting unit setting an area where the vehicle can travel based on a position of the obstacles, and sets the target parking position in the travelable area, a route generation unit calculating a travel route to the target parking position in the travelable area, and a parking execution unit that causes the vehicle to travel toward the target parking position on the basis of the travel route. The route generation unit generates a route from a parking start position to the target parking position, and corrects a distance of the section to a predetermined distance when the distance of the section is less than the predetermined distance.

Abstract: A parking assist device capable of parking assistance that ensures high accuracy of a parking location is provided. A parking assist device that assists in performing an operation of parking a vehicle includes a parking-allowing location calculation unit that before the vehicle stops at a parking-allowing location, calculates and updates the parking-allowing location a plurality of times, and a parking route calculation unit that calculates a parking route. The parking route calculation unit sets a minimum turning radius for calculating the parking route, based on the amount of a shift between the parking-allowing location not updated and the parking-allowing location having been updated, and calculates the parking route, using the minimum turning radius. The minimum turning radius is set larger than the minimum value of a turning radius unique to the vehicle.
