As a result, even if the Pove key is authenticated and started, if there is no fingerprint recognition, a state such as a speed limit, an alarm, or a trunk and a glove box is generated, thereby preventing theft of the vehicle.

FIGS. 3A and 3B are flowcharts illustrating operations performed in the vehicle security enhancement and comfort device control system using fingerprint recognition according to the present invention. The operations performed by the main control unit 200 are as follows. First, (S110-S105; FIG. 3A) for registering the fingerprint of the driver by confirming the driver's fingerprint, and a device control step (S112-S119;

The fingerprint registration step (S100-S105) includes checking whether a user fingerprint registration request exists (S100), receiving the fingerprint of the driver for fingerprint registration through the fingerprint recognition unit 210 (Step S102). In step S103, the fingerprint data stored in the fingerprint storage unit 220 is registered as a user fingerprint in step S103. In step S103, A step of outputting an error message indicating that the fingerprint is wrongly inputted (S104), confirming whether there is a request for canceling the fingerprint registration mode, and ending the fingerprint registration operation or receiving a fingerprint for registering a fingerprint of a new driver (S105). ≪ / RTI >

As shown in FIG. 3B, the fingerprint authentication and device control steps S112 to S119 are performed when the user fingerprint registration request is not requested (N branch of S100) (S112, S113), inputting a fingerprint for fingerprint registration through the fingerprint recognition unit 210 (S114), determining whether the fingerprint is recognizable (S115), recognizing (S116) comparing the fingerprint stored in the fingerprint storage unit 220 with the fingerprint stored in the fingerprint storage unit 220 (S116), and outputting an error message indicating that the fingerprint is erroneously inputted (S117), activating all the functions of the vehicle when the driver's identity authentication is completed, and controlling the convenience device according to the personalization set values of the driver who has recognized the fingerprint (S118).

The overall operation of the vehicle security enhancement and convenience device control system using fingerprint recognition according to the present invention having such a configuration will be described.

First, in the initial state, when the driver (or manager) sets the fingerprint registration mode through the key operation of the setting unit, the main control unit 200 confirms whether there is a request to register the driver fingerprint as illustrated in FIG. 3A S100) and activates the sensor of the fingerprint recognition unit 210 so that the fingerprint of the driver can be input.

In the active state of the sensor, when the driver places a finger for fingerprint registration on the sensor, the fingerprint recognition unit 210 receives the fingerprint data of the driver (S101) and transmits the fingerprint data to the main control unit 200. In the main control unit 200, And determines whether or not the currently inputted fingerprint data is recognizable fingerprint (S102).

If it is determined in step S102 that the fingerprint data currently input is fingerprint data that can be recognized (Y branch in S102), the input fingerprint data is stored and registered in the fingerprint storage unit 220 as the driver fingerprint (S103) If it is determined in step S102 that the currently input fingerprint data is not fingerprint data that can be recognized (step N2 of S102), an error message indicating that the fingerprint data is erroneously input is output (S104) The process returns to the input step S101.

Thereafter, the driver (or the manager) confirms whether there is a request to release the fingerprint registration mode through the key operation of the setting unit (S105), and ends the fingerprint registration operation or receives the fingerprint for registering the fingerprint for the new driver ).

When the engine is started by the FOB key in the state where the fingerprint of the driver is registered in this manner (Y branch of S112), the main controller 200 controls the engine start by the FOB key (S113 And activates the sensor of the fingerprint recognition unit 210 so that the fingerprint of the driver can be input.

When the finger touches the sensor for fingerprint authentication in the activated state of the fingerprint recognition sensor, the fingerprint recognition unit 210 receives the fingerprint data of the driver (S114) and transmits the fingerprint data to the main control unit 200, The state of the fingerprint data is checked and it is judged whether or not the currently input fingerprint data is recognizable fingerprint or not (S115).

If it is determined in step S115 that the currently input fingerprint data is not recognizable fingerprint data (N branch of S115), an error message indicating that the fingerprint data is erroneously inputted is output (S117), and a new fingerprint for the driver is input again The fingerprint storage unit 220 stores the fingerprint data inputted in step S114 as a result of the determination in step S115 if the currently input fingerprint data is recognizable fingerprint data (Y branch in step S115) And compares with the registered driver fingerprint (S116), and carries out the authentication of the driver with the driver's identity.

As a result of the determination (S116), if the currently entered fingerprint data matches the fingerprint data registered in the fingerprint storage unit 220 (Y branch in S116), the main control unit 200 determines that the authentication of the driver's identity through fingerprint recognition is completed , And is stored in the memory of the pre-stored driver including one or more items selected from the sports / comfort / eco control method according to the position and angle of the seat for the fingerprint authenticated driver, the position of the steering wheel, The driver convenience device is controlled according to the personalization setting value (S118).

If it is determined in step S116 that the currently input fingerprint data does not match the fingerprint data registered in the fingerprint storage unit 220 (N branch of S116), the main control unit 200 determines whether the fingerprint data (Or global) box and the trunk are not released from the locked state, and in order to prevent the vehicle from being stolen and misused, a predetermined speed, for example, The traveling device is interrupted (S119) so as to limit the maximum traveling speed to a predetermined speed (for example, 30 km / h) or less and an anti-theft device (immobilizer or the like) Respectively.
