Abstract

An opening-closing member control device includes a motor that opens and closes an opening-closing member of a vehicle, and a control unit configured to stop the motor when determining that a foreign object has been entrapped by the opening-closing member and reverse the motor when a delay time elapses after stopping the motor. When the control unit determines that entrapment has occurred upon operation of a remote operation switch that is separated from the vehicle, the control unit reverses the motor after the delay time that is shorter than when determining that entrapment has occurred upon operation of a vehicle operation switch that is arranged in the vehicle.

First claim

The invention claimed is:

1. An opening-closing member control device, comprising:
a motor that is configured to open and close an opening-closing member of a vehicle; and
a control unit configured to (i) stop the motor from continuing to close the opening-closing member immediately upon the control unit determining that a foreign object has been entrapped by the opening-closing member and (ii) reverse the motor after a delay time elapses after stopping the motor;
wherein:
the control unit is configured such that, if the control unit determines that the foreign object has been entrapped during operation of the opening-closing member by a remote operation switch that is separated from the vehicle, the control unit sets the delay time at a first delay time;
the control unit is configured such that, if the control unit determines that the foreign object has been entrapped during operation of the opening-closing member by a vehicle operation switch that is in the vehicle, the control unit sets the delay time at a second delay time; and
the first delay time is shorter than the second delay time.

2. The opening-closing member control device according to claim 1 , wherein the control unit is configured such that if the control unit determines that the foreign object has been entrapped during the operation of the opening-closing member by the remote operation switch, the first delay time does not vary depending on a driving state of the motor.

3. The opening-closing member control device according to claim 1 , wherein the control unit is configured such that, if the control unit determines that the foreign object has been entrapped during the operation of the opening-closing member by the remote operation switch, the first delay time varies depending on a driving state of the motor.

4. The opening-closing member control device according to claim 3 , wherein the control unit is configured to vary the first delay time in relation to a rotation speed of the motor such that, as the rotation speed increases, the first delay time decreases.

5. The opening-closing member control device according to claim 3 , wherein the control unit is configured to vary the first delay time in relation to a rotation speed of the motor such that the first delay time increases when the rotation speed increases.

6. The opening-closing member control device according to claim 1 , wherein the control unit is configured to execute correction control that corrects an entrapment determination threshold value for determining that the foreign object has been entrapped to decrease an entrapment load if an ambient temperature is greater than or equal to a normal temperature determination threshold value, and corrects the entrapment determination threshold value to increase the entrapment load if the ambient temperature is less than the normal temperature determination threshold value.

7. The opening-closing member control device according to claim 6 , wherein the control unit is configured to execute the correction control such that the entrapment load decreases as a voltage applied to the motor increases.

8. The opening-closing member control device according to claim 6 , wherein the control unit is configured to execute the correction control based on an actuation load on the motor if the ambient temperature is in a range of the normal temperature determination threshold values.

9. The opening-closing member control device according to claim 6 , wherein the control unit is configured to execute the correction control under any one of conditions including the opening-closing member is operated by the vehicle operation switch, the opening-closing member is operated by a the remote operation switch, and the opening-closing member is closed as ignition is turned off and a vehicle door detected by a switch shifts from a closed state to an open state.
