  • Patent number: 10550620
    Abstract: An entrapment detection sensor that detects entrapment caused by an opening/closing body includes an anode sensor electrode and a cathode sensor electrode. The anode sensor electrode is set on the opening/closing body at a location where entrapment caused by the opening/closing body occurs. The cathode sensor electrode is set on the opening/closing body at a location spaced apart by a gap from the anode sensor electrode. The entrapment detection sensor detects a charged object that approaches the anode sensor electrode as an entrapment subject and cancels detection of the charged object that approaches the cathode sensor electrode.

  • Publication number: 20180258680
    Abstract: An opening/closing control device that controls movement of an opening/closing body is provided. The opening/closing control device includes a movable portion configured to move in cooperation with the movement of the opening/closing body and an entrapment detection sensor arranged on the movable portion. The entrapment detection sensor is configured to perform entrapment detection when the opening/closing body moves. The opening/closing control device further includes a control unit that moves the opening/closing body at a constant speed. The control unit is configured to execute deceleration control that changes a movement speed of the opening/closing body to a lower speed than the constant speed when the entrapment detection sensor detects a physical quantity that is less than a first threshold value and greater than or equal to a second threshold value.

  • Publication number: 20180223588
    Abstract: An opening/closing controller includes an entrapment detection sensor that detects entrapment when an opening/closing body moves. A control unit performs a switch mode control using the entrapment detection sensor as an input switch for an opening/closing body operation when detecting an operation input to the entrapment detection sensor while movement of the opening/closing body is stopped.

  • Publication number: 20180202213
    Abstract: An opening/closing control device controls movement of an opening/closing body. The opening/closing control device includes an entrapment detection sensor configured to perform entrapment detection in a closing movement of the opening/closing body, a pulse generator configured to generate pulses in accordance with a movement speed of the opening/closing body, and a control unit configured to determine that the opening/closing body has reached a fully-closed position when the entrapment detection sensor detects entrapment after the pulses generated by the pulse generator indicates that movement of the opening/closing body has stopped.
