  • Publication number: 20180266159
    Abstract: A vehicular opening/closing body control device includes a braking controller configured to apply a braking force to an opening/closing body, a full-closing detection unit configured to detect that the opening/closing body is in a fully-closed state, and a failure detection unit configured to detect failure of a latch mechanism provided on the opening/closing body. The latch mechanism is provided with a pawl switch, which is switched between ON and OFF states in conjunction with operation of a pawl. The failure detection unit detects, based on the ON and OFF states of the pawl switch, occurrence of an engagement failure in which the latch mechanism fails to hold the opening/closing body in the fully-closed state. The braking controller executes braking control for applying the braking force to the opening/closing body when the engagement failure is detected in the latch.

  • Patent number: 9790727
    Abstract: A vehicle opening and closing body control device includes an opening and closing drive device and a controller. When the opening and closing body is being closed, in a case where the position of the opening and closing body when a trapping of a foreign object is detected is outside a specified range between a fully closed position and a specified position, the controller controls the operation of the opening and closing drive device to reverse the opening and closing body to perform the opening operation by a predetermined opening-and-returning distance and then stop the opening and closing body. In a case where the position of trapping is in the specified range, the controller reverses the opening and closing body to perform the opening operation by the predetermined opening-and-returning distance or a greater distance and then stop the opening and closing body outside the specified range.

  • Patent number: 9677313
    Abstract: A vehicle-door opening/closing control device includes a controller, which controls the operation of a drive device. The controller is configured to supply drive power based on a voltage of an in-vehicle power supply to an electromagnetic clutch. The controller is also configured such that, when stopping an opening/closing body at an intermediate position, the controller supplies the drive power based on the voltage of the in-vehicle power supply to the electromagnetic clutch to put the clutch in the engaged state, and then stops the supply of drive power to the electromagnetic clutch so that the clutch is in the disengaged state after a predetermined holding time has elapsed since the controller has stopped the opening/closing body at the intermediate position. The predetermined holding time differs between a case where the trapping of the foreign object is detected and a case where the opening/closing manipulation is detected.

  • Patent number: 9567790
    Abstract: An opening/closing body control device for a vehicle is provided with a drive section configured to drive an opening/closing body of a vehicle, and a controller configured to control the drive section. In response to detection of an external force input intended to accelerate the opening/closing body in operation, the controller controls the drive section to increase the operating speed of the opening/closing element. The drive section determines that the external force intended to accelerate the opening/closing body has been input if, as one example, the acceleration of the opening/closing body in an operation direction reaches a predetermined value or higher.
