Description

Starting control system for a car by using fingerprint recognition and method

The present invention relates to a start control device for a vehicle, and more specifically, by using a fingerprint recognition, in the case of a non-authenticator, it is possible to prevent the operation of the vehicle by the non-authenticator by preventing the subsequent operation after the start or start of the vehicle. The present invention relates to a vehicle starting control device using a fingerprint recognition and a method thereof.

In general, a person who owns a car pays great attention to the prevention of theft of his car and takes his own measures. As part of such countermeasures, electronic door alarms are commonly encountered in the vicinity. This electronic door alarm generates an alarm when the door of the car is opened, and it can be said that the acoustic effect by sound is relatively large. However, there is a problem that the electronic door alarm causes noise pollution around the door by simply unconditionally alarming the door even when the door is opened even in a normal case irrelevant to the occurrence of the theft situation.

Another form of a conventional vehicle anti-theft or lock device is a method of hanging a chain on a wheel of a vehicle. Although this is the most primitive method, it is very effective considering only the effect of preventing theft of the vehicle. However, this method of using the chain is a disadvantage in that it is cumbersome to use and in some cases may damage the vehicle.

The present invention has been made in view of the above problems, and in the case of a non-authenticator using fingerprint recognition, a fingerprint that can prevent the operation of the vehicle by the non-authenticator by disabling subsequent operation after the start of the vehicle. It is an object of the present invention to provide a vehicle start control device using the recognition and a method thereof.

According to the voice message storage unit 204 The voice output unit (speaker) 206 for outputting the voice message stored in the) and the control unit 203 and the fingerprint recognition unit 202 is located between the control unit 203 and the fingerprint recognition unit 202 or A selection switch unit 207 for selectively connecting a corresponding device element according to a situation so as to enable signal transmission / reception between the main controller 210 and the vehicle 203 is provided. Preferably, a voice amplifier 208 is further provided between the controller 203 and the voice output unit 206 to amplify and output the voice message output through the voice output unit 206.

Here, the key operation unit 201 is a registration key used to register by inputting a fingerprint, a deletion key used to delete a registered fingerprint, and used to release and restore a fingerprint recognition function. It consists of fingerprint recognition release / recovery key.

Although not shown in detail in the drawing, the fingerprint recognition unit 202 is provided with a window through which the user's fingerprint can be transmitted and a scanning system that scans the fingerprint transmitted through the window. Such a scanning system may employ a conventional scanning system. In addition, the fingerprint recognition unit 202 has a memory for storing a fingerprint previously input by a main user (administrator).

The start control device for a vehicle using the fingerprint recognition according to the present invention having the above configuration is electrically connected to the main controller 210 of the vehicle (for example, connected by RS232-C), and the main controller 210 is connected to the main controller 210. The start control function is performed by controlling the subsequent operation after starting or starting of the vehicle by signal transmission / reception with each other, and is mounted and used inside the vehicle as shown in FIG. 3. Here, the power for driving the start control device of the present invention may be provided separately, it is preferable to use the power (DC + 5V) supplied from the main controller 210 of the vehicle.

Then, the operation of the start control device for a vehicle using the fingerprint recognition according to the present invention having the above configuration will be described.

4 is an example of a flowchart illustrating a process of first inputting a user's fingerprint by using a vehicle starting control device using fingerprint recognition according to the present invention.

Referring to FIG. 4, first, the user (main manager) presses the registration key of the key operation unit 201 (step 401). Then, a corresponding signal is transmitted to the control unit 203, which controls the pre-set voice message stored in the voice message storage unit 204, for example, a voice message such as "Please enter a fingerprint." Call out and export through the voice output unit 206. Accordingly, the user (primary administrator) enters his or her fingerprint (step 402). That is, the user's finger (mainly the thumb) on the window in the state that the cover (normally the cover is closed) of the fingerprint recognition unit 202 of the start control device 200 using the fingerprint recognition of the present invention is opened. Touching will cause the scanner inside the window to scan your fingerprint, which will allow you to enter your fingerprint. Here, the opening and closing system of the cover of the fingerprint recognition unit 202 may be configured as an automatic opening and closing system using a touch sensor that operates according to whether the object is in contact, or may be configured as a manual opening and closing system that is opened and closed manually by a user. have.

In this way, when the user inputs the fingerprint, it is transmitted to the control unit 203, and the control unit 203 determines whether the fingerprint is correctly input (step 403). In other words, the controller 203 determines whether the input fingerprint is suitable enough to be sufficiently utilized as registration data according to a preset fingerprint registration criteria. In this determination, if the fingerprint is correctly input, the control unit 203 once again sends out a voice message requesting fingerprint input (for reconfirmation of the primary input fingerprint), so that the user once again prints the fingerprint. Is entered (step 404). Then, the fingerprint recognition unit 202 compares the first input fingerprint (stored in the memory in the fingerprint recognition unit) with the second input fingerprint and transmits the result to the controller 203. Then, the controller 203 determines whether there is an abnormality between the first and second input fingerprints based on the transmission data from the fingerprint recognition unit 202 (step 405). If no abnormality is found between the two fingerprints in this determination (i.e., if the two fingerprints are the same), the control unit 203 displays no abnormality through the display unit 205 (in the present invention, Arabic numeral "0" is displayed through the display window). (Step 406). At the same time, the control unit 203 sends out a predetermined voice message (for example, a message such as "fingerprint has been registered") through the voice output unit 206 (step 407). In this way, fingerprint registration of the main user (administrator) is completed.

On the other hand, if the fingerprint is not correctly input in step 403 or if there is an error between the first and second input fingerprints in step 405 (if the two fingerprints are not the same), the controller 203 determines whether all of the set time has elapsed. (Step 408). That is, the timer (not shown) in the control unit 203 counts the elapsed time from the moment when the main user (administrator) first presses the registration key for fingerprint registration. This is such that the program is configured in advance so that fingerprint registration is completed within a predetermined time period (for example, 3 or 5 minutes).

As a result of the determination in step 408, if all of the set time has not elapsed, it is determined whether the error is the third time (step 409). In this determination, if the error is not the third time, the control unit 203 sends out a voice message via the voice output unit 206, for example, requesting fingerprint input again, such as "Please try again." Accordingly, the user enters the fingerprint again. On the other hand, if all the time set in step 408 has elapsed, the process of the fingerprint input program is terminated. If the error is the third time in step 409, error processing (for example, a voice message such as "Failed to register fingerprint" is sent) is performed (step 410), and the program is terminated.

On the other hand, Figure 5 is a flow chart showing a start ON / OFF control mechanism by the vehicle start control device using a fingerprint recognition in accordance with the present invention.

Referring to FIG. 5, a user (here, the user may be a main user or any other user) may first cover the fingerprint recognition unit 202 of the starting control device for a vehicle using the fingerprint recognition of the present invention. Is opened (step 501).

Then, recognizing that the cover is open, the control unit 203 sends out a voice message such as "Please input the fingerprint" through the voice output unit 206. Accordingly, the user enters a fingerprint (step 502), the fingerprint recognition unit 202 is a registered fingerprint stored in the input fingerprint and its own internal memory (where the registration fingerprint may be one person, It may be a number of people) and the result is transmitted to the control unit 203. Then, the controller 203 determines whether there is an abnormality of the currently input fingerprint, that is, whether the currently input fingerprint is an authenticated fingerprint, based on the transmission data from the fingerprint recognition unit 202 (step 503). In this determination, if the input fingerprint is an authenticated fingerprint, the control section 203 outputs a control signal relating to starting or starting maintenance (step 504). The control signal output from the control unit 203 is transmitted to the main controller 210, the main controller 210 is a control corresponding to the signal, for example, after starting or starting (in this case, the remote controller 220 (Fig. 2). Control to enable the subsequent operation of the vehicle), or to maintain the current starting state.

On the other hand, in step 503, if the input fingerprint is not an authenticated fingerprint, the controller 203 recognizes the state as an error and determines whether the error is the third time (step 505). If the error is not the third time in this determination, the control unit 203 outputs a voice message such as "Please input the fingerprint again" via the voice output unit 206. Accordingly, the user enters the fingerprint again. If the error is the third time in step 505, that is, three consecutive unauthenticated fingerprints are input, the control unit 203 performs error processing (for example, "fingerprint authentication failed" or "authentication". Send a voice message such as "not a fingerprint." (Step 506), and transmit a corresponding signal to the main controller 210. Then, the main controller 210 performs the control accordingly, and as a result the start is released.

As described above, although the present invention has been described by means of a limited embodiment and drawings, the present invention is not limited to the above, and the person of ordinary skill in the art to which the present invention pertains should have Of course, various modifications and variations are possible within the scope of the claims.

As described above, the start control device for a vehicle using the fingerprint recognition according to the present invention controls the use of the fingerprint recognition so that subsequent operation after starting or starting the car in the case of the non-authenticator, the operation of the vehicle by the non-authenticator Can be prevented at the source, thereby preventing accidents due to theft of the vehicle or misoperation of children.
