Abstract

A starting system for an engine of an automotive vehicle having an ignition system includes a fingerprint sensor (26) that generates a fingerprint signal. A memory has a plurality of authorized fingerprint signals stored therein. A switch (28) is used to generate a start signal. A controller is coupled to the ignition system (20), the fingerprint sensor (26), the memory (18), and switch (28). The controller compares the fingerprint signal with the authorized fingerprint signal stored in the memory and enables the ignition system in response to the start signal and the fingerprint signal being substantially equal to an authorized fingerprint signal.

Claims

1. A switch assembly for an automotive vehicle comprising:

a pivoting member having a first position and a second position;

a spring urging said pivoting member into said first position;

a fingerprint sensor disposed on said pivoting member;

a first housing disposed adjacent to said pivoting member; and

a switch disposed on said housing so that when said pivoting member is in said second position said switch is closed.

2. A switch assembly as recited in claim 1 further comprising an instrument panel, said pivoting member pivotally coupled to said instrument panel.

3. A switch assembly as recited in claim 1 wherein said switch comprises a non-key-activated switch.

4. A starting system for an engine of an automotive vehicle having an ignition system coupled to the engine, said system comprising:

a switch assembly comprising,

a pivoting member having a first position and a second position;

a spring urging said pivoting member into said first position;

a fingerprint sensor disposed on said pivoting member;

a first housing disposed adjacent to said pivoting member; and

a switch disposed on said housing so that when said pivoting member is in said second posit on said switch generates a start signal;

a memory having n authorized fingerprint signal stored therein; and

a controller coupled to the ignition system, said fingerprint sensor, said memory and said switch, said controller comparing said fingerprint signal with said authorized fingerprint signal a d enabling said ignition system in response to said start signal and said fingerprint signal being substantially equal to said authorized fingerprint signal.

5. A starting system as recited in claim 4 further comprising an instrument panel, said pivoting member pivoting relative to said instrument panel.

6. A starting system as recited in claim 4 further comprising an indicator coupled to said controller.

7. A starting system as recited in claim 6 wherein said indicator comprises a multicolor light emitting diode assembly.

8. A starting system as recited in claim 7 wherein each color of said multicolor light emitting diode indicates a status level.

9. A method of starting an engine of an automobile comprising:

generating a first fingerprint signal from a fingerprint sensor disposed on a pivoting member;

comparing said first fingerprint signal with a second fingerprint signal stored within a memory;

issuing a fingerprint enable signal in response to said first fingerprint signal being within said memory;

generating a start signal by pivoting said pivoting member to contact a mechanical switch; and

starting an engine in response to said start signal and said fingerprint enable signal.

10. A method as recited in claim 9 wherein generating a start signal comprises issuing a start command.

11. A method as recited in claim 9 further comprising the step of generating a stop signal.

12. A method as recited in claim 9 wherein generating a stop signal comprises issuing a stop voice command.

13. A method as recited in claim 9 wherein generating a stop signal comprises activating the mechanical switch.

14. A method as recited in claim 9 further comprising generating a status level via an indicator.

15. A method as recited in claim 9 further comprising enabling a guest mode.

16. A method as recited in claim 9 wherein enabling a guest mode comprises recognizing an authorized user and within a predetermined time reading a guest fingerprint;

and storing said fingerprint in said memory.
