  • Patent number: 11180946
    Abstract: A door opening/closing device includes a detection unit which detects a foot of a person present near a front door; and a vehicle door opening/closing device main body which opens a rear slide door, when the detection unit detects the foot of the person, wherein when the foot of the person is not detected within a prescribed time after being detected, the detection unit outputs a pseudo outer door handle switch on signal which demands the vehicle door opening/closing device main body to open the rear slide door, and when detection is continuously performed during a prescribed time or longer from when the detection unit has detected a detection target, the detection unit does not output the pseudo outer door handle switch on signal.

  • Patent number: 10760322
    Abstract: In a state that an engine is started up by using a mobile device from outside a vehicle, a power mode changeover switch is switched from a fixed contact OFF to a fixed contact START while avoiding a fixed contact ACC and a fixed contact ON, and the power mode changeover switch is maintained at the fixed contact START even after the engine is placed in an operation state. When an electric power is not supplied through the fixed contact ACC, a detection unit places itself in a state in which a detection operation is possible, and when the electric power is supplied, the detection unit places itself in a detection operation prohibition state.

  • Patent number: 10738527
    Abstract: A vehicle door opening/closing device includes a front door configured to open and close a front left opening of a vehicle body, a rear sliding door configured to open and close a rear left opening of the vehicle body, a vehicle door opening/closing device main body configured to automatically open and close the rear sliding door, a detection unit configured to detect the presence of the left foot of a user, and a control unit (detection ECU, door lock ECU, sliding door driving ECU). If the front door is in an opened state at the time when the detection unit detects the presence of the left foot, the control unit does not put the rear sliding door into a closed state.
