Patent ID: 8405515

Claim:
A control device comprising: an electric wave sensor set with a first detection region; an electrostatic capacity sensor set with a second detection region; and a control unit for controlling locking and unlocking of a door of a vehicle based on a detection result by the electric wave sensor and a detection result by the electrostatic capacity sensor, wherein the electric wave sensor is variably set with the detection region, wherein a first distance with respect to the door of the vehicle is set as the first detection region in the electric wave sensor, wherein a second distance shorter than the first distance is set as the second detection region in the electrostatic capacity sensor, wherein when a state of the door of the vehicle is a locked state, the control unit performs a control to unlock the door when the object is detected by the electric wave sensor, and wherein when the state of the door of the vehicle is an unlocked state: if the object is detected by both the electrostatic capacity sensor and the electric wave sensor, the control unit performs a control to lock the door, and if the object is detected by the electrostatic capacity sensor but is not detected by the electric wave sensor, the control unit decides not to perform the control to lock the door.
