Abstract

An entry assist system for a motor vehicle includes a door, a door operation module to open and close the door and a starter actuator for starting an engine of the motor vehicle. The entry assist system further includes a control subsystem. The control subsystem includes a gesture sensor and a controller. The controller is responsive to the gesture sensor to open the door and start the engine of the motor vehicle.

Claims

1. An entry assist system for an operator of a motor vehicle, comprising:

a door;

a door operation module to open and close said door;

a starter actuator to start an engine of said motor vehicle; and

a control subsystem including a gesture sensor for detecting a gesture made by said operator and a controller, said controller being responsive to said gesture to open said door and start said engine.

2. The system of claim 1, wherein said gesture sensor is carried on an exterior of said vehicle and monitors a scan field adjacent a bottom edge of said door.

3. The system of claim 1, wherein said control subsystem further includes an entry sensor to detect an individual entering said vehicle through an opening created when said door is opened.

4. The system of claim 3, wherein said controller is responsive to said entry sensor to close said door.

5. The system of claim 1, wherein said door operation module includes a lock actuator to latch and unlatch a latch on said door and a door actuator to open and close said door.

6. The system of claim 5, wherein said entry assist system includes a key fob carried by an operator of said vehicle that transmits an authorized operator code.

7. The system of claim 5, wherein said control subsystem includes a receiver for receiving said authorized operator code from said key fob, said controller opening said door and starting said vehicle only after confirming said authorized operator code matches a predetermined authorized operator code for the motor vehicle.

8. The system of claim 7, further including a second door and a second door operation module.

9. The system of claim 8, wherein said second door operation module includes a second lock actuator to latch and unlatch a second latch on said second door and a second door actuator to open and close said second door.

10. The system of claim 9, wherein said control subsystem includes a second gesture sensor associated with said second door, said controller being responsive to said second gesture sensor to open and close said second door.

11. A method of assisting an operator to enter a motor vehicle, comprising:

detecting, by gesture sensor, a gesture made by said operator;

opening, by a door actuator, a door of said vehicle in response to said gesture; and

starting, by a starter actuator, an engine of said vehicle in response to said gesture.

12. The method of claim 11, further including detecting a vehicle operator authorization code comparing the detected vehicle authorization code to a predetermined vehicle authorization code for said motor vehicle and confirming that said detected vehicle authorization code and said predetermined authorization code match before opening said door and starting said engine.

13. The method of claim 12, further including detecting entry of an individual into said vehicle through an opening created when said door is opened before starting said engine.

14. The method of claim 13, further including closing said door in response to detecting entry of said individual into said vehicle.
