AUTOMATED VALET PARKING SYSTEM, CONTROL METHOD FOR AUTOMATED VALET PARKING SYSTEM, AND AUTONOMOUS DRIVING VEHICLE

System (1) that causes a first vehicle (N1) and a second vehicle (N2) to perform automated valet parking includes one or more processors configured to cause, a second vehicle (N2) to perform follow-up traveling to follow a first vehicle (N1); set a stop position (D) between the first vehicle (N1) and the second vehicle (N2) when the second vehicle (N2) is performing the follow-up traveling to follow the first vehicle (N1) in the parking place (50); calculate, between the stop position (D) and a position where the second vehicle (N2) starts deceleration to stop at the stop position; and set a target vehicle-to-vehicle distance (L) of the second vehicle (N2) from the first vehicle (N1), and set, as the target vehicle-to-vehicle distance, a distance longer than a sum of the deceleration start distance (Lg) and a margin distance (Lm) from the stop position (D) to the first vehicle (N1).
