Abstract

A key fob for a vehicle that provides a certain vehicle function depending on the motion applied to the key fob. The key fob includes a switch that is pressed when the vehicle operator wishes to transmit a command. Pressing the switch causes a device, such as a camera or accelerometer, to be put in a motion detecting mode, where a subsequent motion of the key fob causes the key fob to transmit a command associated with that motion. For example, the vehicle operator can press the switch on the key fob and make an upward motion, which will cause the vehicle door locks to unlock. Likewise, pressing the switch on the key fob and making a downward motion may cause the door locks to lock.

Claims

1. A unit for providing a command to a vehicle, said unit comprising:

a housing;

a detecting mode switch provided in the housing;

a motion detecting device responsive to a detecting signal from the detecting mode switch that puts the motion detecting device in a detecting mode, said motion detecting device detecting a motion of the unit while it is in the detecting mode; and

a controller responsive to a motion signal from the motion detecting device identifying the motion of the unit, said controller causing a predetermined command signal to be transmitted based on the motion of the unit that performs a predetermined function on the vehicle.

2. The unit according to claim 1 wherein the motion detecting device is an accelerometer.

3. The unit according to claim 1 wherein the motion detecting device is a camera.

4. The unit according to claim 1 wherein an upward motion of the unit identified by the motion detecting device causes the controller to send a command signal to unlock the vehicle doors.

5. The unit according to claim 1 wherein a downward motion of the unit identified by the motion detecting device causes the controller to send a command signal to lock the vehicle doors.

6. The unit according to claim 1 wherein a rotating motion of the unit identified by the motion detecting device causes the controller to send a command signal to start the vehicle.

7. The unit according to claim 1 wherein a sweeping motion of the unit identified by the motion detecting device causes the controller to send a command signal to identify the vehicle.

8. The unit according to claim 1 further comprising a door lock switch and a door unlock switch on the housing.

9. The unit according to claim 8 wherein the unlock switch and the lock switch are in a side panel of the housing of the key fob.

10. The unit according to claim 1 wherein the housing is more than three times as long as it is wide.

11. The unit according to claim 1 further comprising a display that displays an image identifying the command signal sent by the controller.

12. The unit according to claim 1 wherein the housing includes a removable back panel for a valet.

13. A key fob for a vehicle comprising:

a key fob housing;

an accelerometer switch provided in the key fob housing;

an accelerometer responsive to an accelerometer switch signal from the accelerometer switch, said accelerometer detecting a motion of the key fob; and

a controller responsive to an accelerometer control signal from the accelerometer identifying the motion of the key fob, said controller causing a predetermined command signal to be transmitted based on the motion of the key fob that performs a predetermined vehicle function, where the controller provides a command for an upward motion, a downward motion, a rotating motion and a sweeping motion.

14. The key fob according to claim 13 wherein the upward motion of the key fob causes the controller to send a command signal to unlock the vehicle doors, the downward motion of the key fob causes the controller to send a command signal to lock the vehicle doors, the rotating motion of the key fob causes the controller to send a command signal to start the vehicle, and the sweeping motion of the key fob causes the controller to send a command signal to identify the vehicle.

15. The key fob according to claim 13 wherein the only switch on the housing is the accelerometer switch.

16. The key fob according to claim 13 further comprising a door lock switch and a door unlock switch on the housing.

17. The key fob according to claim 16 wherein the unlock switch and the lock switch are in a side panel of the housing of the key fob.

18. The key fob according to claim 13 wherein the housing is more than three times as long as it is wide.

19. The key fob according to claim 13 further comprising a display that displays an image identifying the command signal sent by the controller.

20. A key fob for a vehicle comprising circuitry responsive to an actuation signal, said circuitry wirelessly transmitting a command to the vehicle to perform a vehicle function in response to the actuation signal and a subsequent motion of the key fob.
