Vehicle control method, vehicle control system, and information processing device

A vehicle control system configured to control vehicles adapted to automated valet parking in a parking lot, the vehicle control system comprising:

• one or more storage devices configured to store map information of the parking lot and vehicle information indicating positions of the vehicles in the parking lot;
• and
• one or more processors configured to
• determine whether a retreating vehicle is present based on the map information and the vehicle information, the retreating vehicle being a vehicle that needs to move from a parking slot where the retreating vehicle is parked to move an exiting vehicle scheduled to exit the parking lot,
• determine a retreating route through a retreating route determination process, the retreating route being a traveling route of the retreating vehicle when the retreating vehicle is moved to move the exiting vehicle, the retreating route determination process including
• acquiring traveling route information indicating an exiting route that is a traveling route of the exiting vehicle,
• searching for a non-interfering route that does not interfere with the exiting route based on the map information, the vehicle information, and the traveling route information, and
• determining the non-interfering route as the retreating route, and
• move the retreating vehicle along the retreating route.
