Vehicle-door control device and opening/closing system for vehicle
First Claim
1. A vehicle-door opening and closing body control device, comprising:
- a drive device, which opens and closes an opening and closing body of a vehicle;
a trapping detector, which detects a trapping of a foreign object by the opening and closing body;
an opening and closing manipulation detector, which detects an opening and closing manipulation of the opening and closing body by the drive device; and
a controller, which controls an operation of the drive device such that the opening and closing body is stopped at an intermediate position in an operation range of the opening and closing body when the trapping of the foreign object is detected or when the opening and closing manipulation is detected during an opening operation or closing operation of the opening and closing body, whereinthe drive device includes an electromagnetic clutch, which is configured to transmit a driving force to the opening and closing body and engages or disengages transmission of the driving force between the opening and closing body and a motor as a driving source of the drive device,the controller is configured to supply a drive power from an in-vehicle power supply to the electromagnetic clutch, based on a voltage of the in-vehicle power supply,to stop the opening and 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 electromagnetic clutch in an engaged state and then stops the supply of the drive power to the electromagnetic clutch to put the electromagnetic clutch in a disengaged state after a predetermined holding time has elapsed since the controller has stopped the opening and closing body at the intermediate position, andthe predetermined holding time differs between a case where the trapping of the foreign object is detected and a case where the opening and closing manipulation is detected.

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.
