A parking control method includes: detecting a first parking space based on the ambient image of the vehicle captured by an imaging device; controlling at least a steering actuator of the vehicle to cause the vehicle to be parked in the first parking space; detecting a second parking space based on the ambient image of the vehicle captured by the imaging device, while the vehicle is travelling into the first parking space, the second parking space being adjacent to the first parking space in a travelling direction of the vehicle, the second parking space being farther than the first parking space from the vehicle; and controlling at least the steering actuator of the vehicle to cause the vehicle to be parked in the second parking space.
