  • Publication number: 20210229535
    Abstract: An opening-closing body control device for a vehicle includes: an opening-closing control unit configured to control an operation of an opening-closing body provided in an opening portion of a vehicle by controlling energization of a motor serving as a drive source. When the opening-closing body being moved based on a driving force of the motor is to be stopped, the opening-closing control unit sets a free running period during which free rotation of the motor is allowed, and executes brake control for generating a braking force in the motor after the free running period elapses.

  • Patent number: 7477977
    Abstract: A power window device for use in a vehicle for raising and lowering each window glass. The power window device includes a drive unit for each door operable for raising and lowering the associated window glass. Each drive unit includes an EEPROM for retaining mounting position information of the position in the vehicle at which the window glass driven by the associated drive unit is located. A processor in each drive unit retrieves steering wheel position information of whether the steering wheel is located in the right or left side of the vehicle. The processor recognizes the position in the vehicle at which the associated drive unit is installed based on the mounting position information and the steering wheel information. This enables the drive unit to be used for both right hand and left hand drive vehicles.

  • Patent number: 7357449
    Abstract: A sunroof device includes a roof panel having a first opening portion, a ceiling member having a second opening portion so as to face the first opening portion, a movable panel moved between a full-closed position and an open position, the movable panel passing through a half-closed position, a motor for driving the movable panel, a controlling means for controlling an operation of the motor, an operating member to be operated or released by a passenger in the vehicle, and a switch for inputting an operation signal for operating the motor, and inputting a stop signal for stopping the motor. The controlling means drives the motor until the movable panel reaches the full-closed position while moving towards the full-closed position by the operating member being operated even if the operating member is released after the movable panel reaches the half-closed position.

  • Patent number: 7276872
    Abstract: A power window device for lowering and raising window glasses. A window switch is operated to move a corresponding window glass. A motor drives the window glass when the window switch is operated. An ECU is provided for each window glass to control the motor in accordance with the operation of the window switch. An engine switch shifts positions to drive an engine. A control signal generator generates a signal to validate or invalidate control of the ECU over the motor. A control circuit determines that a signal wire connecting the ECUs to the control signal generator is in an unexpected condition when a signal cannot be received. The control circuit overrides the signals generated by the control signal generator when the signal wire is in an unexpected condition.
