Abstract

A vehicle is provided having a sensor for detecting a vehicle occupant'"'"'s presence, and another sensor for detecting an owner'"'"'s response with respect to automatically opening a vehicle closure panel. An actuator opens the closure panel when the occupant'"'"'s presence and response are detected. A signal from an emitter outside the vehicle signals occupant presence. A photoelectric and/or optical device, audio receiver, and/or touch-sensitive sensor detects the response. The optical device projects a light beam, and breaking the beam with a gesture signals the response. An automatic closure panel opening apparatus has an RF receiver adapted to receive an RF signal to detect occupant presence, a sensor for detecting the occupant response, and an actuator for opening the closure panel when both the presence and occupant response are detected. A method for automatically opening the closure panel includes detecting an occupant presence and response, and automatically opening the closure panel when a predetermined response is detected.

Claims

1. A vehicle comprising:

a closure panel;

an actuator configured to automatically move said closure panel in at least one direction;

a radio frequency (RF) receiver that detects an RF signal emitted by an RF emitter to thereby detect the presence of a potential occupant of the vehicle;

an optical sensor that detects a response of said occupant wherein the optical sensor selectively generates and projects a concentrated light beam onto a surface, and detects a predetermined gesture of the occupant made with respect to the light beam without using the RF receiver; and

a controller having a stored expected response of said occupant that is selectable by the occupant and recorded by the controller to provide a unique coded command, including an expected interruption of the concentrated light beam via the predetermined gesture of the occupant;

wherein said controller receives the detected response of the occupant from the optical sensor, compares said detected response of said occupant to said stored expected response of said occupant, and activates said actuator to thereby automatically move said closure panel in said at least one direction when both said presence is detected and said detected response of said occupant equals said stored expected response of said occupant.

2. The vehicle of claim 1, further comprising an additional sensor that detects the response of said occupant, wherein the additional sensor is selected from the group consisting essentially of an audio receiver, an ultrasonic sensor, a laser sensor, and a touch-sensitive sensor.

3. The vehicle of claim 2, wherein the vehicle rests on the surface, and wherein said optical sensor includes a light emitter configured to project said concentrated light beam onto said surface, and said expected response of said occupant is a predetermined movement or gesture of said occupant in the path of said light beam in a predetermined direction.

4. The vehicle of claim 3, wherein said light emitter is configured to generate a customizable logo and project said customizable logo onto said surface using said light beam.

5. The vehicle of claim 3, further comprising an ultrasonic sensor that determines time and directional information of said gesture.

6. The vehicle of claim 2, including voice recognition software, wherein said additional sensor includes said audio receiver, and wherein said expected response of said occupant is a predetermined word or phrase spoken by said occupant.

7. The vehicle of claim 2, including said touch-sensitive sensor, which detects one of:

a change in a generated electromagnetic field around the touch-sensitive sensor and a change in capacitance around the touch-sensitive sensor.

8. The vehicle of claim 1, wherein said stored expected response of said occupant is programmable into said controller by said occupant.

9. An automatic closure panel opening apparatus for use with a vehicle having a closure panel and an actuator configured for automatically opening and closing the closure panel, the apparatus comprising:

a radio frequency (RF) receiver configured to receive an RF signal from an RF emitter that is positioned external to the vehicle to thereby detect the presence of a potential occupant of the vehicle;

an optical sensor configured to selectively generate and project a concentrated light beam from an underside of the vehicle onto a surface upon which the vehicle rests, and to detect a response of said occupant by detecting a gesture of said occupant at the underside of the vehicle with respect to said concentrated light beam; and

a controller having a stored expected occupant response, including an expected interruption of the concentrated light beam in a predetermined direction, that is selectable by the occupant and recorded by the controller to provide a unique coded command, wherein said controller compares said detected response of said occupant to said stored expected response of said occupant, and activates said actuator to move the closure panel when said presence is detected and when said detected response of said occupant equals said stored expected response of said occupant.

10. The apparatus of claim 9, further comprising an additional sensor that is selected from the group consisting essentially of an audio receiver, an ultrasonic sensor, a laser sensor, and a touch-sensitive device.

11. The apparatus of claim 10, including said ultrasonic sensor, wherein said ultrasonic sensor determines time and directional information of the gesture of said occupant in the path of said light beam.

12. The apparatus of claim 11, wherein said optical sensor includes a light emitter that is configured to generate a customizable logo and projects said customizable logo onto said surface as said light beam.

13. The apparatus of claim 10, including said audio receiver, wherein said expected response of said occupant includes a predetermined word or phrase spoken by said occupant.

14. A method for automatically opening a closure panel of a vehicle comprising:

recording, using a controller, an expected gesture of a potential occupant of the vehicle as a unique coded command;

detecting the presence of the potential occupant of the vehicle using a radio frequency (RF) receiver which receives RF signals from an RF emitter positioned external to the vehicle;

alerting said occupant that said presence has been detected;

generating a light beam, and projecting said light beam from an underside of the vehicle onto a surface on which the vehicle rests;

detecting a gesture of said occupant with respect to said light beam, and without respect to motion of the RF emitter, as a detected response of said occupant, including detecting a direction of said gesture with respect to said light beam;

comparing said detected response of said occupant to a stored expected response of said occupant; and

automatically moving the vehicle closure panel in a predetermined direction via a controller of the vehicle when said detected response of said occupant equals said expected response of said occupant.

15. The method of claim 14, wherein the vehicle includes an ultrasonic sensor, wherein said detecting said direction of said gesture includes ultrasonically detecting time and directional information of said gesture.

16. The method of claim 14, wherein said detecting a response of said occupant further comprises detecting the breaking of a projected light beam using said gesture.

17. The method of claim 14, wherein said detecting a response of said occupant further comprises using speech recognition software to detect an expected word or phrase spoken by said occupant.

18. The method of claim 14, further comprising activating a warning device before opening said closure panel.

19. The method of claim 14, including a touch-sensitive sensor, wherein detecting the gesture includes detecting one of a change in a generated electromagnetic field with respect to the touch-sensitive sensor and a change in capacitance with respect to the touch-sensitive sensor.
