Abstract

A voice activation system for a vehicle. The voice activation system for a vehicle which has at least one sound panel capable of providing vibrations of a user's voice from the outside of the vehicle into an inside area of the vehicle. A laser listening device is operably connected to the panel for receiving vibrations from a user's voice. A controller receives a pre-identified command of the user from the laser listener and operates an action in the vehicle in response thereto.

First claim

What is claimed is:

1. A voice activation system for a vehicle comprising:
a vehicle which includes at least one sound panel capable of reverberating vibrations of a user's voice from the outside of the vehicle;
a laser listening device mounted to a headliner on the inside passenger compartment of the vehicle, the laser listening device projects a laser beam onto a rear window of a vehicle liftgate that is reflected creating a reflected beam that is detected by a photo sensor of the laser listening device allowing for detection of vibrations from a user's voice that are reverberated by the at least one panel, the laser listening device generates a laser listening signal that are indicative of the vibrations detected by the laser listening device, wherein the laser beam, and
a controller for receiving the laser listening signal and determining the presence of a pre-identified command of the user and operating an action in the vehicle in response thereto.

2. The voice activation system for a vehicle of claim 1 wherein the controller is a computer device connect to the vehicle and includes voice activation software programmed onto the controller.

3. The voice activation system for a vehicle of claim 2 wherein said controller also includes control hardware operationally connected to the vehicle for controlling at least one action in the vehicle.

4. The voice activation system for a vehicle of claim 3 wherein the at least one action is one selected from the group including door unlocking, door opening, window opening, vehicle ignition, vehicle lights, opening rear lift gate or trunk, and emergency.

5. The voice activation system of claim 1 wherein the laser beam reflects off the rear window at an angle of about 90 degrees.

6. The voice activation system of claim 1 further comprising a microphone mounted to the exterior of the vehicle, configured to detect sound from the outside of the vehicle and generate a listening signal to the controller, wherein the controller receives both the microphone listening signal and the laser listening signal and performs a comparison to filter out ambient noise from outside the vehicle.

7. A voice activation system for a vehicle comprising:
a vehicle which includes at least one sound panel capable of reverberating vibrations of a user's voice from the outside of the vehicle;
a laser listening device mounted to head rest on the inside passenger compartment of the vehicle, the laser listening device projects a laser beam onto a rear window of a vehicle liftgate that is reflected creating a reflected beam that is detected by a photo sensor of the laser listening device allowing for detection of vibrations from a user's voice that are reverberated by the at least one panel, the laser listening device generates a laser listening signal that are indicative of the vibrations detected by the laser listening device, wherein the laser beam, and
a controller for receiving the laser listening signal and determining the presence of a pre-identified command of the user and operating an action in the vehicle in response thereto.

8. The voice activation system for a vehicle of claim 7 wherein the controller is a computer device connect to the vehicle and includes voice activation software programmed onto the controller.

9. The voice activation system for a vehicle of claim 8 wherein said controller also includes control hardware operationally connected to the vehicle for controlling at least one action in the vehicle.

10. The voice activation system for a vehicle of claim 9 wherein the at least one action is one selected from the group including door unlocking, door opening, window opening, vehicle ignition, vehicle lights, opening rear lift gate or trunk, and emergency.

11. The voice activation system of claim 9 wherein the laser beam reflects off the rear window at an angle of about 90 degrees.

12. The voice activation system of claim 9 further comprising a microphone mounted to the exterior of the vehicle, configured to detect sound from the outside of the vehicle and generate a listening signal to the controller, wherein the controller receives both the microphone listening signal and the laser listening signal and performs a comparison to filter out ambient noise from outside the vehicle.

13. A method of operating a voice activation system on a vehicle comprising the steps of:
providing a vehicle which includes a plurality of window panels each having an outside surface exposed to the exterior of the vehicle and an inside surface exposed to an interior of a passenger compartment of the vehicle;
providing a plurality of laser listening devices located in the interior of the passenger compartment, wherein in each one of the plurality of laser listening devices is positioned relative to the interior surface of a respective one of the plurality of window panels, wherein teach of the plurality of laser listening devices has a laser for projecting a laser beam and a photosensor;
providing a controller having voice activation software programmed on the controller having a pre-identified commands programmed thereon;
generating a laser beam from each of the plurality of laser listening devices onto the inside surface of the respective one of the plurality of window panels and creating a reflected beam that is detected by the photo sensor;
generating a laser listening signal from each of the plurality of laser listening devices and transmitting the laser listening signal to the controller;
using the controller and the voice activation software to perform an analysis of each laser listening signal in order to determine variations in vibrations at each of the plurality of window panels and filtering ambient noise as a result of the analysis;
using the controller to determine is a pre-identified command of a user is present in the laser listening signal;
operating an actuator of a vehicle in response to the pre-identified command.

14. The method of claim 13 wherein the actuator is used to perform one selected from the group comprising door unlocking, door opening, window opening, vehicle ignition, vehicle lights, opening rear lift gage, opening trunk and emergency functions.

15. The method of claim 13 wherein the pre-identified command is a spoken verbal command of any type of spoken language.

16. The method of claim 15 further comprising the steps of:
providing a setup software programmed into the controller allowing the voice activation software to one or more learn spoken word commands; and
training the controller by the user to learn the one or more spoken word commands.

17. The method of claim 13 further comprising the steps of:
providing an identification device capable of being sensed by the controller;
providing a predetermined distance around the vehicle;
operating the actuator only when the identification device is detected within the predetermined distance of the vehicle.

18. The method of claim 17 wherein the identification device is a key fob or smart phone.
