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.

Claims (16)

1. An opening-closing body control device for a vehicle, comprising:

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, wherein

the opening-closing unit receives, from a storage area, a free running period during which free rotation of the motor is allowed, and

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 the free running period received from the storage area, allows the free rotation of the motor while the free rotation of the motor is measured during the free running period, and executes brake control for generating a braking force in the motor after the free running period elapses.

2. The opening-closing body control device for a vehicle according to claim 1 , wherein

the opening-closing control unit sets the free running period based on a predetermined moving distance of the opening-closing body after execution of drive control for generating the driving force in the motor is stopped.

3. The opening-closing body control device for a vehicle according to claim 1 , wherein

the opening-closing control unit sets the free running period based on a predetermined elapsed time after execution of the drive control for generating the driving force in the motor is stopped.

4. The opening-closing body control device for a vehicle according to claim 1 , wherein

the brake control is regenerative brake control.

5. The opening-closing body control device for a vehicle according to claim 1 , wherein

the opening-closing control unit gradually increases the braking force generated in the motor due to execution of the brake control.

6. The opening-closing body control device for a vehicle according to claim 1 , wherein

the opening-closing body is a movable panel of a sunroof device.

7. The opening-closing body control device for a vehicle according to claim 2 , wherein the opening-closing control unit sets the free running period based on a predetermined elapsed time after execution of the drive control for generating the driving force in the motor is stopped, and executes the brake control for generating a braking force in the motor when the predetermined elapsed time elapses before the predetermined movement distance.

8. The opening-closing body control device for a vehicle according to claim 1 , further comprising a drive circuit that supplies driving electric power to the motor, wherein the driving circuit includes field effect transistors, and wherein the opening-closing control unit sets the free running period by executing motor free control in which all of the field effect transistors are turned off.
