Abstract

A multistage vehicle security system includes a transceiver that receives a first signal sent from a transponder and a controller that processes the first signal. The controller activates low level operational features of the vehicle if the signal is associated with an authorized transponder. The system also includes an entry sensor that detects the physical presence of a user. The transponder sends a second signal to the transceiver when the presence of the user is detected. The controller processes the second signal and activates midlevel operational features of the vehicle if the second signal is associated with the authorized transponder. Once the user is inside the vehicle, a sensor detects a biometric characteristic of the user. The user obtains access to one or more high level operational features of the vehicle if the detected biometric characteristic matches that of an authorized user.

Claims

1. A multistage security system for a vehicle, comprising:

a transceiver which receives a first signal sent from a transponder;

a controller which processes the first signal and activates low level operational features of the vehicle if the controller determines that the first signal is associated with an authorized transponder;

an entry sensor which detects the physical presence of a user, the transponder transmiting a second signal to the transceiver when the presence of the user is detected, the controller processing the second signal and activating midlevel operational features of the vehicle if the second signal is associated with the authorized transponder; and

a sensor which detects a biometric characteristic of the user, the user obtaining access to one or more high level operational features of the vehicle if the detected biometric characteristic matches the biometric characteristic of an authorized user.

2. The system of claim 1, wherein the signal from the transponder is associated with long-range wireless communication.

3. The system of claim 1, wherein the biometric characteristic is a voice of the user.

4. The system of claim 1, wherein the biometric characteristic is the fingerprint of the user.

5. The system of claim 1, wherein the transceiver transmits a signal associated with short-range wireless communication to the transponder to detect the physical presence of the user.

6. The system of claim 5, wherein the controller unlocks one or more of the vehicle'"'"'s doors if the transponder is an authorized transponder.

7. The system of claim 1, wherein the low level operational features is selected from the group including climate control, seat settings, entertainment system, glove box, trunk, and ignition.

8. The system of claim 1, wherein the mid level operational features includes access to the vehicle.

9. The system of claim 1, wherein the high level operational features includes vehicle ignition and vehicle transmission and e-commerce vehicle features.

10. The system of claim 1, wherein the biometric characteristic is selected from the group consisting of iris identification, retina scanning, handprint, lightprint, and face recognition.

11. A method of authorizing user access to a vehicle, comprising:

activating a transponder to send a first signal to a transceiver residing in the vehicle;

activating low level operational features of the vehicle if the first signal is associated with an authorized transponder;

detecting the physical presence of the user;

transmitting a second signal from the transponder to the transceiver if the presence of the user is detected;

allowing access to the interior of the vehicle if the second signal is associated with the authorized transponder;

after the user enters the vehicle, sensing one or more biometric characteristics of the user;

comparing the sensed biometric characteristic with a stored biometric characteristic; and

enabling access to one or more high level operational features of the vehicle if the biometric characteristic matches with the stored biometric characteristic.

12. The method of claim 11, wherein the signal from the transponder is associated with long-range wireless communication.

13. The method of claim 11, wherein the biometric characteristic is a voice of the user.

14. The method of claim 11, wherein the biometric characteristic is a fingerprint of the user.

15. The method of claim 11, wherein the transceiver transmits a signal associated with short-range wireless communication to the transponder to detect the physical presence of the user.

16. The method of claim 15, wherein the controller unlocks one or more of the vehicle'"'"'s doors if the transponder is an authorized transponder.

17. The method of claim 11, wherein the biometric characteristic is selected from the group consisting of iris identification, retina scanning, handprint, lightprint, and face recognition.
