Abstract

An active door edge guard system is provided for a motor vehicle. That system includes a door edge guard, an electronic actuator for displacing the door edge guard between the stowed position and the deployed position, a door motion sensor and a controller. The controller is responsive to the door motion sensor and is configured to activate the electronic actuator to deploy the door edge guard as the motor vehicle door is opened and stow the door edge guard as the motor vehicle door is closed.

Claims

1. An active door edge guard system for a motor vehicle, comprising:

a rigid door edge guard;

an electronic actuator for displacing said door edge guard between a stowed position and a deployed position;

a door motion sensor; and

a controller responsive to said door motion sensor to activate said electronic actuator as needed to protect an edge of a motor vehicle door.

2. The active door edge guard system of claim 1 wherein said door motion sensor is a Hall effect sensor.

3. The active door edge guard system of claim 2, wherein said Hall effect sensor is carried on said motor vehicle door and monitors a door check assembly of said motor vehicle door.

4. The active door edge guard system of claim 1, wherein said door motion sensor is a proximity sensor that monitors a door check assembly for said motor vehicle door.

5. The active door edge guard system of claim 1, wherein said door motion sensor is a dedicated accelerometer carried on said motor vehicle door.

6. The active door edge guard system of claim 5, wherein said electronic actuator includes a housing and said dedicated accelerometer is carried on said housing.

7. The active door edge guard system of claim 1, wherein said door motion sensor is an existing side door impact sensor of a motor vehicle safety system.

8. The active door edge guard system of claim 1, wherein said door motion sensor is a door ajar sensor.

9. The active door edge guard system of claim 8, wherein said door ajar sensor includes a plunger.

10. The active door edge guard system of claim 1, wherein said controller is configured to activate said electronic actuator to deploy said door edge guard as said motor vehicle door is opened and stow said door edge guard as said motor vehicle door is closed.

11. The active door edge guard system of claim 1, wherein said controller is configured to provide a time delay between the moment of receiving a door open signal and the activation of the actuator to displace the door edge guard into said deployed position.

12. A method protecting an edge of a motor vehicle door from damage due to contact/impact with another object when opened, comprising:

monitoring, by door motion sensor, movement of said motor vehicle door between closed and opened positions; and

activating, by controller, an electronic actuator for displacing a door edge guard between a stowed position and a deployed position protecting said edge of said motor vehicle door.

13. The method of claim 12 including monitoring a door check assembly of said motor vehicle door to verify movement of said motor vehicle door between said closed and opened positions.

14. The method of claim 12 including using a Hall effect sensor to monitor movement of said motor vehicle door between said closed and opened positions.

15. The method of claim 12 including using an accelerometer to monitor movement of said motor vehicle door between said closed and opened positions.

16. The method of claim 12, including using a plunger to monitor movement of said motor vehicle door between said closed and opened positions.
