Abstract

A power window control device is configured to control a motor to open and close a window glass of a vehicle door and perform entrapment prevention control that determines entrapment of foreign material by the window glass and reverses the window glass if determining that foreign material entrapment has occurred. If determined in the entrapment prevention control that the entrapment has occurred while the window glass is closing to fully close, the entrapment prevention control determines whether the determination is caused by an impact generated when closing the vehicle door. If determined that the entrapment has occurred due to an impact generated when closing the vehicle door, the entrapment prevention control determines that the determination of the entrapment is an erroneous determination and switches to a control for fully closing the window glass that has been reversed and opened.

First claim

The invention claimed is:

1. A power window control device comprising an electronic control unit configured to:
control a motor to open and close a window glass of a vehicle door;
perform an entrapment prevention control process that makes a determination that a possibility that foreign material is entrapped by the window glass and reverses movement of the window glass from closing the window glass to opening the window glass when the electronic control unit determines, via the entrapment prevention control process, the possibility that foreign material entrapment has occurred;
determine, when the electronic control unit makes the determination, via the entrapment prevention control process, that the possibility that entrapment has occurred while the window glass is closing to fully close, whether the determination is caused by an impact generated when closing the vehicle door; and
switch, when the electronic control unit determines that the determination is caused by the impact generated when closing the vehicle door, to a control for fully closing the window glass that has been reversed and opened.

2. The power window control device according to claim 1 , wherein the electronic control unit is configured such that the electronic control unit determines whether the determination is caused by the impact generated when closing the vehicle door from at least one of a signal from a courtesy switch that detects an open and a closed position of the vehicle door and a signal from an acceleration sensor that detects acceleration of a vehicle that includes the power window control device in a predetermined direction.

3. The power window control device according to claim 1 , wherein the electronic control unit is configured such that the electronic control unit determines whether the determination is caused by the impact generated when closing the vehicle door from a signal of a camera that detects an open and a closed position of the vehicle door.

4. The power window control device according to claim 1 , wherein the electronic control unit is configured such that the electronic control unit determines whether the determination is caused by the impact generated when closing the vehicle when the window glass starts closing to fully close within a preset time from when an ignition switch is switched off.

5. The power window control device according to claim 1 , wherein the electronic control unit is configured such that, when the electronic control unit determines that the determination is caused by the impact generated when closing the vehicle door, the electronic control unit automatically starts full closing to fully close the window glass that has been reversed and opened.

6. The power window control device according to claim 1 , wherein the electronic control unit is configured such that, when the electronic control unit determines that the determination is caused by the impact generated when closing the vehicle door, the electronic control unit starts full closing in accordance with a lock instruction signal from a door lock switch that is remotely operated to fully close the window glass that has been reversed to open.

7. The power window control device according to claim 1 , wherein the electronic control unit is configured such that, when the electronic control unit determines that the determination is caused by the impact generated when closing the vehicle door, the electronic control unit controls a sound generating device to generate a notification sound before or while fully closing the window glass that has been reversed and opened.

8. A power window control device configured to control a motor to open and close a window glass of a vehicle door, comprising:
a motor controller; and
a processor that determines a possibility that foreign material is entrapped by the window glass;
wherein the power window control device is configured to:
reverse movement of the window glass from closing of the window glass to opening of the window glass when the processor determines the possibility that foreign material is entrapped by the window glass;
determine, when the processor determines the possibility that foreign material is entrapped by the window glass, whether the determination is caused by a closing of the vehicle door; and
switch, when the power window control device determines that the determination is caused by the closing of the vehicle door, to a control for fully closing the window glass.

9. A power window control device comprising an electronic control unit configured to:
control a motor to open and close a window glass of a vehicle door, determine that foreign material is entrapped by the window glass and reverse movement of the window glass from closing the window glass to opening the window glass when the electronic control unit makes a determination that the foreign material is entrapped by the window glass;
determine, when the electronic control unit makes the determination that the foreign material is entrapped by the window glass while the window glass is closing to fully close, whether the determination is caused by an impact generated when closing the vehicle door; and
switch, when the electronic control unit determines that the determination is caused by the impact generated when closing the vehicle door, to a control for fully closing the window glass that has been reversed and opened.

10. A vehicle door with a window glass and a power window control device comprising:
a motor configured to open and close the window glass; and
an electronic control unit configured to:
control the motor to open and close the window glass;
determine that foreign material is entrapped by the window glass and reverse movement of the window glass from closing the window glass to opening the window glass when the electronic control unit makes a determination that the foreign material is entrapped by the window glass;
determine, when the electronic control unit makes the determination that the foreign material is entrapped by the window glass while the window glass is closing to fully close, whether the determination is caused by an impact generated when closing the vehicle door; and
switch, when the electronic control unit determines that the determination is caused by the impact generated when closing the vehicle door, to a control for fully closing the window glass that has been reversed and opened.
