Abstract

A touch vehicle control system having a gesture interface device with one or more touchless sensors that detect a position of a driver'"'"'s appendage within a range of movement detected by the sensors. The touchless sensors send a signal to the controller that is indicative of the position of the driver'"'"'s appendage within the range of movement which is then interpreted to be a vehicle command signal for a vehicle'"'"'s mechanical system. Command signals include, but are not limited to acceleration, braking, parking brake, turn signals, etc.

Claims

1. A touch free vehicle control system comprising:

a controller capable of controlling acceleration and braking of a vehicle; and

an interface device having at least one touchless sensor configured to detect a plurality of gestures and a plurality of positions of at least one appendage of a driver within a range of movement without any physical touching between the at least one touchless sensor and the at least one appendage, wherein the at least one touchless sensor is configured to send a command signal to the controller that is indicative of at least one of the plurality of gestures and the plurality of positions of the appendage within the range of movement, wherein different movements of the appendage cause the controller to generate different command signals from the controller; and

a plurality of spring-loaded finger pedals positioned at a location relative to the at least one touchless sensor allowing the at least one touchless sensor to send a signal to the controller that is indicative of the position the at least one appendage, wherein a first finger pedal of the plurality of finger pedals is configured to be interpreted by the controller to be one of the plurality of gestures and defines a first range of movement for an accelerator pedal, and wherein a second finger pedal of the plurality of finger pedals is configured to be interpreted by the controller to be another of the plurality of gestures and defines a second range of movement for a brake pedal, wherein depressing the first finger pedal causes the controller to cause acceleration of the vehicle and depressing the second finger pedal causes the controller to cause braking of the vehicle based on the position of the at least one appendage in the range of movement, wherein the position of the at least one appendage within the range of movement controls at least one of a magnitude of acceleration and a magnitude of braking.

2. The touch free vehicle control system of claim 1, wherein the at least one touchless sensor is a plurality of touchless sensors that comprises a plurality of cameras.

3. The touch free vehicle control system of claim 2, wherein the plurality of touchless sensors comprises a plurality of infrared sensors.

4. The touch free vehicle control system of claim 3, wherein the controller is configured to cause acceleration and braking of the vehicle based solely on the position of the at least one appendage in the range of movement.

5. The touch free vehicle control system of claim 4, wherein the gesture interface device further includes an enclosed well containing the plurality of touchless sensors and the first and second finger pedals, the enclosed well defining an aperture configured to allow the driver to place the at least one appendage within the enclosed well to access the first and second finger pedals to prevent accidental movement in the area of the plurality of touchless sensors.

6. The touch free vehicle control system of claim 4, wherein the gesture interface device further includes an enclosed well containing the plurality of touchless sensors, the enclosed well defining an aperture configured to allow the driver to place the at least one appendage within the enclosed well so that movement of the at least one appendage is detected by the plurality of touchless sensors and accidental movement in the range of movement is prevented.

7. The touch free vehicle control system of claim 4, wherein the different command signals generated from the controller include signals operating a vehicle function selected from the group consisting of:

acceleration, braking, parking brake on, parking brake release, door lock, door unlock, window actuators, door actuators, hood release switch, fuel door release switch, radio controls, telephone controls, navigation controls, interior light controls, exterior light controls, cruise controls, turn signal controls, hazard signal controls, odometer controls, vehicle information center controls, media player controls and window wiper controls and combinations thereof.

9. A touch free vehicle control system comprising:

a controller capable of controlling acceleration and braking of a vehicle; and

a gesture interface device having a plurality of touchless sensors, the plurality of touchless sensors comprising at least one of the following;

a charge coupled device, infrared sensors, digital cameras, and motion detectors, the plurality of touchless sensors being configured to directly detect a gesture and a position of a driver'"'"'s appendage within a range of movement without any physical touching between the plurality of touchless sensors and the driver'"'"'s appendage, the plurality of touchless sensors being configured to send a command signal to the controller that is indicative of the gesture and the position of the driver'"'"'s appendage within the range of movement, wherein different movements of the driver'"'"'s appendage cause the controller to generate different command signals from the controller; and

a plurality of spring-loaded finger pedals positioned at a location relative to the plurality of touchless sensors, wherein a first finger pedal of the plurality of finger pedals is configured to be interpreted by the controller to define a first range of movement for an accelerator pedal, and wherein a second finger pedal of the plurality of finger pedals is configured to be interpreted by the controller to define a second range of movement for a brake pedal, wherein depressing the first finger pedal causes the controller to cause acceleration of the vehicle and depressing the second finger pedal causes the controller to cause braking of the vehicle based on the position of the driver'"'"'s appendage in the range of movement, wherein the position of the driver'"'"'s appendage within the range of movement controls at least one of a magnitude of acceleration and a magnitude of braking.

8. The touch free vehicle control system of claim 14, wherein the plurality of touchless sensors comprises at least one of a charge coupled device and a motion detector.

10. The touch free vehicle control system of claim 9, wherein the plurality of touchless sensors that comprises a plurality of cameras.

11. The touch free vehicle control system of claim 10, wherein the plurality of touchless sensors comprises a plurality of infrared sensors.

12. The touch free vehicle control system of claim 11, wherein the controller is configured to cause acceleration and braking of the vehicle based solely on the position of the at least one appendage in the range of movement.

13. The touch free vehicle control system of claim 12, wherein the gesture interface device further includes an enclosed well containing the plurality of touchless sensors and the first and second finger pedals, the enclosed well defining an aperture configured to allow the driver to place the driver'"'"'s appendage within the enclosed well to access the first and second finger pedals to prevent accidental movement in the area of the plurality of touchless sensors.

14. The touch free vehicle control system of claim 12, wherein the gesture interface device further includes an enclosed well containing the plurality of touchless sensors, the enclosed well defining an aperture configured to allow the driver to place the driver'"'"'s appendage within the enclosed well so that movement of the driver'"'"'s appendage is detected by the plurality of touchless sensors and accidental movement in the range of movement is prevented.
