- the position of the operator is detected, and in the width direction of the passage for the vehicle.
- the rescue position is set on the side where the operator is located, and the vehicle is moved along a rescue route ending at the rescue position.
- the vehicle stops at a position relatively close to the operator, so that the operator can get into the vehicle.
- the control device 10 detects the parked vehicle from the captured image of the camera group 1 and recognizes the passage for the vehicle from the arrangement of the parked vehicles. May be For example, the control device 10 may identify the passage for the vehicle from the direction along the front or rear of the plurality of parked vehicles. This can improve the accuracy of identifying the passage for the vehicle.
- the present invention has been described by taking the case where the rescue position is set at a position where the traveling direction is substantially parallel to the passing direction of the passage for vehicles.
- the rescue position is set so that the traveling direction is substantially parallel to the passing direction of the passage for the vehicle, and the rescue position is made the end point.
- a rescue route may be generated.
