By selectively operating (137) and the selection key 138, a setting password and a confirmation password are respectively input, and it is determined whether or not the selection key 138 is pressed (S310).

Here, the password is set to 8 digits, for example, and the user may input the power mode key 131, the auto idle key 132, the up key 133, the display / ESC key 134, and the work mode key 135. ), The flow control key 136, the down key 137 and the selection key 138 are selectively operated to input all eight-digit passwords, and it is determined whether the selection key 138 is pressed.

As a result of the determination, when the user inputs all the passwords and presses the selection key 138, the instrument panel controller 250 determines whether the set password and the confirmation password coincide with each other (S312). If it is determined that the setting password and the confirmation password do not match, the password setting screen is displayed again (S308) to allow the user to input the setting password and the confirmation password again.

When the setting password and the confirmation password coincide with each other as a result of the determination, the instrument panel controller 250 stores the setting password in the second memory 258 (S314), and generates a security code to the second memory 258. Save (S316).

Here, the security code can be generated in various ways. For example, the user may generate a combination of various information of the vehicle, including a password set by the user, a current date, a model of the vehicle, and a serial number previously provided to the main controller 200. In addition, the password, the current date, and the information of the vehicle may be generated by combining the predetermined function.

And the instrument panel control unit 250 generates a security code storage signal for requesting the storage of the generated security code and transmits it to the main control unit 200 (S318), and then transmits the generated security code to the main control unit 200. It transmits (S320).

Meanwhile, as shown in FIG. 4A, when the security code storage signal is input from the instrument panel controller 250, the main controller 200 determines whether the security code is stored in the first memory 206. It is determined (S402).

When the security code is stored in the first memory 206 as a result of the determination, the main controller 200 ignores the security code storage signal (S404) and stores the security code input from the instrument panel controller 250. I never do that.

When the security code is not stored in the first memory 206 as a result of the determination, the main control unit 200 first inputs a security code transmitted from the instrument panel control unit 250 to store the security code for the first time. Stored in memory 206.

That is, in the present invention, when the user of the vehicle sets a password, the instrument panel controller 250 stores the password and generates a security code, and the instrument panel controller 250 stores the generated security code in the second memory 258. ) Is stored in the first memory 206 and transmitted to the main controller 200.

When the password is stored in the second memory 258 as a result of the determination in step S306, the instrument panel controller 250 determines resetting of the password and displays the display panel 120 through the display panel driver 256. In step S322, a password input screen is displayed. For example, as illustrated in FIG. 5C, a password input screen for allowing a user to input a password is displayed.

In this state, the user presses the power mode key 131, the auto idle key 132, the up key 133, the display / ESC key 134, the work mode key 135, the flow control key 136, and the down key. When the password is input by selectively operating 137 and the selection key 138 (S324), and the selection key 138 is pressed, the instrument panel controller 250 stores the input password and the second memory 258 in advance. It is determined whether or not the corresponding passwords match (S326).

When the password input by the user and the preset password match as a result of the determination, the instrument panel control unit 250 reads the security code from the second memory 258, and the read security code to the main control unit 200. After transmission (S328), it is determined whether or not a security approval is input from the main control unit 200 (S330).

On the other hand, the main control unit 200 compares the security code stored in the first memory 206 when the security code is input from the instrument panel control unit 250 (S408) (S410), the security code as a result of the comparison If is matched (S412) to approve the security, and transmits the security approval to the instrument panel control unit 250 (S414).

When the security approval is input from the main controller 200 (S330), the instrument panel controller 250 controls the display panel driver 256 to display a password setting screen on the display panel 120 (S332). For example, a password setting screen as shown in FIG. 5B is displayed.

The instrument panel control unit 250 inputs a setting password and a confirmation password through the password setting screen (S334), and when the setting password and the confirmation password match (S336), the setting password is input to the second memory 258. Save and update the password (S338).

And the instrument panel control unit 250 generates a security code to update and store in the second memory 258 (S340), and generates a security code update signal for requesting the update and storage of the generated security code to the main control unit 200 In step (S342), and then transmits the updated security code to the main control unit 200 (S344).

On the other hand, the main control unit 200 inputs the security code to be updated (S418) when the security code update signal is input from the instrument panel control unit 250 after the security is approved (S414). The security code is updated and stored in the first memory 206 (S420).

That is, in the present invention, when the user renews the password, the password is updated after receiving the security approval of the main control unit 200, and a new security code is generated together with the update of the password, and the generated security code is the instrument panel control unit. The 250 stores the update in the second memory 258 and transmits the same to the main controller 200 to store the update in the first memory 206.

When the user does not select the password setting on the main menu screen (S304), and selects the lock / unlock setting (S346), the instrument panel controller 250 may enter, for example, a password input screen as shown in FIG. 5C. It is displayed (S348).

In this state, the user presses the power mode key 131, the auto idle key 132, the up key 133, the display / ESC key 134, the work mode key 135, the flow control key 136, and the down key. When a password is input by selectively operating 137 and the selection key 138 (S350), and the selection key 138 is pressed, the instrument panel control unit 250 stores the input password and the second memory 258 in advance. It is determined whether or not the corresponding passwords match (S352).

When the password input by the user and the preset password match as a result of the determination, the instrument panel control unit 250 reads the security code from the second memory 258, and the read security code to the main control unit 200. After transmission (S354), it is determined whether a security approval is input from the main controller 200 (S356).

When the security approval is input from the main controller 200 as a result of the determination (S330), the instrument panel controller 250 controls the display panel driver 256 to display a lock / unlock setting screen on the display panel 120. (S358). For example, the lock / unlock setting screen as shown in Fig. 5D is displayed.

In this state, when the user operates the up key 133 and the down key 137 to set the lock or unlock (S360), the instrument panel controller 250 sets the lock or unlock setting state to the second memory 258. In operation S362, a lock or unlock update signal is transmitted to the main controller 200 (S364).

Meanwhile, after the security is approved (S414) and the lock or unlock update signal is input from the instrument panel controller 250 (S422), the main controller 200 updates and stores it in the first memory 206 (S422). S424).

That is, in the present invention, when the user sets the lock or unlock, the lock or unlock is set after receiving the security approval of the main control unit 200, and transmitted to the main control unit 200 to be updated and stored in the first memory 206. do.

On the other hand, when the user inserts the ignition key to the start switch unit 202, and rotates, the start switch unit 202 generates a start command to be input to the main control unit 200.

The main controller 200 determines whether a security code is stored in the first memory 206 when a start command is input from the start switch unit 202 as shown in FIG. 4B (S426). S428), if the security code is not stored, it is determined whether or not the current lock is set (S430).

When the security code is not stored in the first memory 206 or the security code is stored in the first memory 206 as a result of the determination, the main control unit 200 issues a start command of the vehicle. By controlling the vehicle starting unit 204 to start the vehicle, so that the user can drive normally.

When the security code is stored in the first memory 206 and the current lock is set, the main controller 200 requests the security code from the instrument panel controller 250 (S432). It is determined whether the security code is input from the panel controller 250 (S434).

The instrument panel controller 250 controls the display panel driver 256 when the request signal of the security code is input from the main controller 200 as shown in FIG. 3B to control the display panel 120. A password input screen is displayed (S368). For example, a password input screen is displayed as shown in FIG. 5C.

When a password is input by selectively operating the password 137 and the selection key 138 (S370), the instrument panel controller 250 determines whether the input password matches the password previously stored in the second memory 258. Determine (S372).

When the passwords match the determination result, the instrument panel control unit 250 clears all the count values counted up to now (S374). That is, both the count value counting the number of inconsistencies of the password described later and the count value of the security code request times are cleared.

And the instrument panel control unit 250 reads the security code stored in the second memory 258 and transmits it to the main control unit 200 (S376).

When the security code is input from the instrument panel controller 250 (S434), the main controller 200 determines whether the input security code matches the security code stored in the first memory 206. If the security code matches (S436), the security is approved (S438), and the vehicle starting unit 204 is controlled according to the above-described start command to start the vehicle (S440), and the vehicle can be driven normally.

When the password does not match as a result of the determination in step S372, the instrument panel controller 250 counts the number of inconsistencies in which the passwords do not match (S378), and determines whether the number of inconsistencies in the counted passwords is greater than or equal to a preset number. It is determined whether or not (S380). For example, it is determined whether the number of password mismatches is three or more times.

When the number of inconsistencies of the password is not more than a preset number of times, the instrument panel control unit 250 displays the input screen of the password again (S368), inputs the password (S370), and the input password is stored in advance with the password. The operation (S372) of determining whether or not coincidence is repeatedly performed.

When the number of inconsistencies of the password is equal to or more than a predetermined number of times, the instrument panel controller 250 counts the number of security code requests (S382). That is, each time a start command is generated from the start switch unit 202, the number of security code requests input from the main control unit 200 is counted.

It is determined whether the counted number of security code requests is greater than or equal to a preset number of times (S384). For example, it is determined whether the count value of the security code request count is three or more times.

As a result of the determination, when the number of times the request of the security code is not more than a predetermined number of times, the operation of the vehicle is stopped so that a password can no longer be input (S386).

In this state, when the user operates the start key again, the start switch unit 202 generates a start command as described above, and the instrument panel when the main control unit 200 transmits a security code request signal according to the start command generated. The controller 250 receives the password as described above, and when the number of inconsistencies of the input password is not less than the set number of times, and the count value of the security code request signal is not more than the set number of times, the controller 200 stops the operation of the vehicle. Repeat the operation to stop.

When the count value of the security code request signal is greater than or equal to the set number of times as a result of the determination in step S384, the instrument panel controller 250 stops the operation of the vehicle so that a password can no longer be input (S388) and theft detection is performed. The signal is generated and transmitted to the main controller 200 (S390).

After the main control unit 200 requests the security code (S432), when the security code is not input from the instrument panel control unit 250 (S434), and when a burglar detection signal is input (S442), the first memory 206 The phone number stored in advance is read in (S444), the phone number is dialed through the communication unit 210, and then theft detection signal is transmitted to request help (S446).
