Abstract

A motor vehicle is provided with a usage authorization checking device that detects biometric data of a person with a biometric sensor configuration. If the usage authorization check, performed with biometrically detected data, is positive, the vehicle can be put into operation by performing a predetermined actuation without actuating a separate ignition or starter switch. A separate ignition or starter switch is eliminated. The driving motor can be an electric motor or an internal combustion engine. The predetermined actuation can include movement of an accelerator pedal, a transmission shift lever, a clutch pedal and a brake pedal. The biometric sensor configuration can also include connections to a driving motor start-up device and a shut-off device.

Claims

1. A method for placing a motor vehicle driving motor into operation by an authorized user, which comprises:

detecting biometric characteristics of a user;

checking if the user is an authorized operator by comparing data derived from the detection of the user'"'"'s biometric characteristics with data stored in memory;

disengaging the motor vehicle driving motor immobilizer if the usage authorization check is positive without the user having to actuate a separate, portable control element for an ignition or starter switch; and

actuating at least one actuating element necessary for driving the vehicle in a predetermined way to place the driving motor into operation.

2. The method according to claim 1, wherein the driving motor is an internal combustion engine and the step of actuating at least one actuating element necessary for driving the vehicle in a predetermined way starts the engine.

3. The method according to claim 2, wherein the step of actuating at least one actuating element necessary for driving the vehicle in a predetermined way is an actuation of an accelerator pedal.

4. The method according to claim 2, wherein the step of actuating at least one actuating element necessary for driving the vehicle in a predetermined way is an actuation of a shift lever for shifting a transmission.

5. The method according to claim 4, wherein the transmission is an automatic transmission and the step of actuating at least one actuating element necessary for driving the vehicle in a predetermined way is an actuation of a brake pedal and a movement of the shift lever into a driving stage.

6. The method according to claim 4, wherein the transmission is a manual transmission and the step of actuating at least one actuating element necessary for driving the vehicle in a predetermined way is an actuation of a clutch pedal and a movement of the shift lever into a driving gear.

7. The method according to claim 2, wherein the step of actuating at least one actuating element necessary for driving the vehicle in a predetermined way is an actuation of an accelerator pedal and an actuation of a clutch pedal.

8. The method according to claim 2, wherein the step of actuating at least one actuating element necessary for driving the vehicle in a predetermined way is an actuation of a shift lever for shifting a transmission and an actuation of a clutch pedal.

9. An apparatus for placing a motor vehicle driving motor into operation, comprising:

a biometric sensor configuration for detecting biometric data of a person and deriving calculation data by a predetermined algorithm;

a control unit having a memory device for storing authorization data and the calculation data, and a comparator for comparing the authorization data with the calculation data and generating a calculation signal if the authorization data and the calculation data are substantially similar; and

at least one sensor connected to said control unit for detecting an actuation of at least one actuating element of the motor vehicle required for driving the motor vehicle, said control unit placing the motor vehicle driving motor into operation upon actuation of the at least one actuating element in a predetermined way.

10. The apparatus according to claim 9, wherein said control unit places the motor vehicle internal combustion engine into operation upon actuation of the at least one actuating element in a predetermined way.

11. An apparatus for placing a motor vehicle driving motor into operation, comprising:

a biometric sensor configuration for detecting biometric data of a person and deriving calculation data by a predetermined algorithm, said biometric sensor configuration having a biometric sensor region for detecting a fingerprint pattern and at least two spacing sensor regions adjacent said biometric sensor region; and

a control unit having;

a memory device for storing authorization data and the calculation data;

a comparator for comparing the authorization data with the calculation data and generating a calculation signal if the authorization data and the calculation data are substantially similar; and

an immobilization disengagement device releasing a vehicle immobilization device and placing the vehicle in an operative state when said calculation signal is generated.

12. The apparatus according to claim 11, wherein a first of said at least two spacer sensor regions is connected to a start-up device of the driving motor and a second of said at least two spacing sensor regions is connected to a shut-off device of the driving motor.

13. The apparatus according to claim 11, wherein said at least two spacing sensor regions are disposed on opposite sides of said biometric sensor region.

14. The apparatus according to claim 11, wherein said two spacing sensor regions are disposed adjacent said biometric sensor region at a bottom of a channel.
