Abstract

Person authentication for determining if there is a specified driver is performed by biometrics or the like. Then when authenticated that there is a previously registered driver, it is predicted that the engine will be started, and prior to the driver operating the ignition key, operation of a fuel pump, or a heater fitted to an engine fuel injection valve, is commenced. Thereafter when the ignition key is operated by the driver, control shifts to normal control.

Claims

1. An apparatus for performing start preparation for a vehicular engine, comprising:

means for performing person authentication; and

means for commencing electric power supply to an electric heater provided in the engine prior to starting the engine as start preparation for the engine, when a specified person is authenticated by the means for performing person authentication.

2. An apparatus for performing start preparation for a vehicular engine, comprising:

a first section for performing person authentication; and

a second section for commencing electric power supply to an electric heater provided in the engine prior to start the engine, as start preparation for the engine, when a specified person is authenticated by the first section for performing person authentication.

3. An apparatus for performing start preparation for a vehicular engine according to claim 2 wherein,

the first section for performing person authentication performs person authentication based on a driving license.

4. An apparatus for performing start preparation for a vehicular engine according to claim 2, further comprising:

a third section for stopping operation of the second section for commencing electric power supply to the electric heater, when an operating time of the second section exceeds a threshold value.

5. An apparatus for performing start preparation for a vehicular engine according to claim 2, further comprising:

a fourth section for permitting starting of the engine, when a specified person is authenticated by the first section for performing person authentication.

6. An apparatus for performing start preparation for a vehicular engine according to claim 2, further comprising:

a fifth section for detecting a movable body in the vicinity of a vehicle; and

a sixth section for supplying electric power to the first section for performing person authentication and the second section for commencing electric power supply to the electric heater, when the movable body in the vicinity of the vehicle is detected.

7. An apparatus for performing start preparation for a vehicular engine according to claim 6, further comprising:

a seventh section for measuring a time from after supplying electric power to the first section for performing person authentication and the second section for commencing electric power supply to the electric heater; and

an eighth section for cutting off power supply to the first section for performing person authentication and the second section for commencing electric power supply to the electric heater, when the time exceeds a threshold value.

8. An apparatus for performing start preparation for a vehicular engine according to claim 2, further comprising:

a ninth section for detecting a movable body in the vicinity of a vehicle;

a tenth section for outputting a warning, when the movable body is detected;

an eleventh section for canceling operation of the tenth section for outputting a warning; and

a twelfth section for supplying electric power to the first section for performing person authentication and the second section for commencing electric power supply to the electric heater, when operation of the tenth section for outputting a warning is cancelled.

9. A method of performing start preparation for a vehicular engine, comprising the steps of:

performing start preparation; and

commencing electric power supply to an electric heater provided in the engine prior to starting the engine, as start preparation for the engine, when a specified person is authenticated.

10. A method of performing start preparation for a vehicular engine according to claim 9 wherein,

performing person authentication comprises the following steps of:

reading information of a driving license; and

performing person authentication based on the information read.

11. A method of performing start preparation for a vehicular engine according to claim 9, further comprising the steps of:

measuring a time while the start preparation is performed;

determining whether or not the time exceeds a threshold value; and

stopping performance of the start preparation, when the time exceeds the threshold value.

12. A method of performing start preparation for a vehicular engine according to claim 9, further comprising the step of:

permitting starting of the engine, when the specified person is authenticated.

13. A method of performing start preparation for a vehicular engine according to claim 9, further comprising the following steps of:

detecting a movable body in the vicinity of a vehicle; and

permitting execution of the person authentication and execution of the start preparation, when the movable body is detected in the vicinity of the vehicle.

14. A method of performing start preparation for a vehicular engine according to claim 13, further comprising the following steps of:

measuring a time from after permitting execution of the person authentication and execution of the start preparation; and

canceling execution of the person authentication and execution of the start preparation, when the time exceeds a threshold value.

15. A method of performing start preparation for a vehicular engine according to claim 9, further comprising the following steps of:

detecting a movable body in the vicinity of a vehicle;

outputting a warning, when the movable body is detected;

canceling output of the warning; and

permitting execution of the person authentication and execution of the start preparation, when output of the warning is cancelled.
