Then, for example, when the key position detection unit 12 detects that the electronic key 20 is not in the vehicle interior 55 and the door open / close detection unit 14 detects that all the doors 51 and 52 are closed, the control unit 11 Determines that the lock condition is satisfied (step S2: YES). In this case, the control unit 11 locks all the doors 51 and 52 by the door lock device 35 (step S3). In other words, the accepted reservation lock is realized (reservation lock success).

On the other hand, for example, the key position detection unit 12 detects that the electronic key 20 is in the passenger compartment 55, or the door open / close detection unit 14 detects that at least one of the doors 51 and 52 is open. If this happens, the control unit 11 determines that the lock condition is not satisfied (step S2: NO). In this case, the control unit 11 leaves all the doors 51 and 52 as they are (step S4). As a result, of all the doors 51 and 52, the already locked door is locked as it is, and the unlocked door is unlocked. That is, the accepted reservation lock is not realized, and at least one of the doors 51 and 52 is unlocked (reservation lock failure).

Then, the control unit 11 transmits a start prohibition command to the engine drive device 29 via CAN (Controller Area Network) or the like to prohibit the engine 28 from starting (step S5). While the start of the engine 28 is prohibited, even if the start switch 39 is operated, the engine drive 29 does not drive the starter motor, so that the engine 28 does not start.

Further, although not shown in FIG. 3, when the control unit 11 determines that the lock condition is not satisfied (step S2: NO) and leaves the doors 51 and 52 as they are (step S4), the alarm device An alarm is output by 36. Specifically, for example, the buzzer and horn of the vehicle 50 included in the alarm device 36 are sounded, and the lights of the vehicle 50 are turned on and blinked.

After that, when the start switch 39 is operated to start the engine 28 (step S6: YES), the engine 28 has not started yet at this point, and the input request unit 15 communicates with the navigation device 37 by CAN or the like. To do. Then, the input request unit 15 displays the password input screen 60 (FIG. 4) requesting the input of the password for canceling the start prohibition of the engine 28 on the touch pad 38 of the navigation device 37 (step S7).

FIG. 4 is a diagram showing a password input screen 60. As shown in FIG. 4, the password input screen 60 is provided with a message 61 requesting password input, a password input field 62, and a plurality of soft keys 63 to 66. In addition to these, a message notifying that the engine 28 is currently prohibited from starting and a wording indicating that the password is for canceling the engine 28 starting prohibition are displayed on the password input screen 60.

The soft key 66 is a key for determining the entered password.

In FIG. 4A, since numbers (“0” to “9”) are displayed on each softkey 63, by touch-operating each softkey 63, the number corresponding to the operated softkey 63 can be obtained. Entered. In FIG. 4A, by touch-operating the softkey 64, letters or symbols are displayed on each softkey 63 as shown in FIG. 4B. In FIG. 4B, by touching each softkey 63 once or a plurality of times, an alphabetic character or a symbol corresponding to the operated softkey 63 is input. For example, by touching the soft key 63 on which "ABC" is displayed once, twice, or three times, lowercase letters "a", "b", or "c" are input, and four times, By touching the button 5 or 6 times, the uppercase letters "A", "B", or "C" are input. Further, in FIG. 4B, by touching the softkey 64, a number is displayed on each softkey 63 as shown in FIG. 4A.

When a number, a letter, or a symbol is input by touching the soft key 63, "*" is displayed in the input field 62 instead of the input information, as shown in FIG. 4 (b). Then, when the soft key 66 is touch-operated, the input information (character string) is determined as a password and transmitted from the navigation device 37 to the control unit 11.

When the input determination unit 16 receives (acquires) the password from the navigation device 37, the input determination unit 16 compares the password with a specific password that can be known only to the user of the vehicle 50 stored in advance. Then, when both passwords match, the input determination unit 16 determines that the correct password has been input.

Further, after step S7 in FIG. 3, the control unit 11 detects the position of the electronic key 20 by the key position detection unit 12. Then, when it is detected that the electronic key 20 is in the passenger compartment 55 and the input determination unit 16 determines that the correct password has been input (step S8: YES), the control unit 11 causes the engine. A start prohibition release command is transmitted to the drive device 29 to release the start prohibition of the engine 28 (step S9). As a result, when the start switch 39 is operated again, the engine drive device 29, which receives the notification from the control unit 11 that the authentication of the electronic key 20 is successful, drives the starter motor to start the engine 28.

After step S9, the input request unit 15 sends a display stop command to the navigation device 37 to stop (turn off) the display of the password input screen 60 by the touch pad 38 (step S10).

On the other hand, when the password is not entered on the above password input screen 60, or when the password is entered but the password does not match the specific password, the input determination unit 16 inputs the correct password. It is determined that there is no such thing (step S8: NO). In this case, the start prohibition state of the engine 28 and the display of the password input screen 60 by the touch pad 38 are continued.

Further, after step S7, when the key position detection unit 12 detects that the electronic key 20 is not in the passenger compartment 55 (step S8: NO), the start prohibition state of the engine 28 and the password by the touch pad 38 are also obtained. The display of the input screen 60 is continued.

According to the first embodiment described above, after accepting the reservation lock that automatically locks the doors 51 and 52 of the vehicle 50, at least one of the doors 51 and 52 is not satisfied because the predetermined lock condition is not satisfied. Is in the unlocked state, that is, when the reserved lock cannot be realized, the start of the engine 28 of the vehicle 50 is prohibited. Therefore, for example, even if the electronic key 20 of the vehicle 50 is left behind in the passenger compartment 55, after a malicious third party opens the unlocked doors 51 and 52 and invades the passenger compartment 55, The engine 28 cannot be started, and it is possible to prevent the vehicle 50 from being stolen.

Further, in the first embodiment described above, the input request unit 15 is installed in the vehicle interior 55 when the start of the engine 28 is prohibited because the lock condition is not satisfied after the reservation lock is accepted. The password input screen 60 is displayed by the touch pad 38 of the navigation device 37, and the user of the vehicle 50 is requested to input the password. Then, when the touch pad 38 is operated by the user and a specific password that only the user can know is input, the start prohibition of the engine 28 is released. Therefore, the user can easily cancel the start prohibition of the engine 28 by performing a simple operation of inputting the correct password on the password input screen 60 displayed by the navigation device 37. After that, by operating the start switch 39, the engine 28 can be started and the vehicle 50 can be driven. On the other hand, a malicious third party cannot enter the correct password on the password input screen 60, cannot lift the prohibition on starting the engine 28, and cannot start the engine 28. Therefore, it is possible to more effectively prevent the theft of the vehicle 50 by a malicious third party.

Further, in the first embodiment described above, when the electronic key 20 is in the passenger compartment 55 and the correct password is entered on the password input screen 60, the prohibition on starting the engine 28 is released. That is, after confirming the success of the double authentication of the electronic key 20 and the password, the start prohibition of the engine 28 is lifted, so that the engine 28 is prevented from being started by a malicious third party, and the vehicle 50 It is effective in surely preventing the theft of the engine.

Further, in the first embodiment described above, when the start switch 39 is operated after prohibiting the start of the engine 28, the input request unit 15 displays the password input screen 60 on the touch pad 38 of the navigation device 37. And ask the user to enter the password. Therefore, even if the start switch 39 is operated but the engine 28 does not start, the user is made to recognize that the start of the engine 28 is prohibited, and the password for canceling the prohibition is input. Can be prompted to the user. Further, since the password input screen 60 is not displayed on the touch pad 38 of the navigation device 37 until the start switch 39 is operated, the power of the battery of the vehicle 50 consumed for performing the display can be suppressed. ..

Further, in the above-described first embodiment, the input of a specific password is adopted as a method for canceling the start prohibition of the engine 28. Since the specific password is known only to the user of the vehicle 50 and is difficult to be known by a malicious third party, it is necessary to prevent the prohibition of starting the engine 28 from being lifted by the malicious third party. It is valid.

Alternatively, a predetermined operation of the switch, knob, lever, pedal, or handle provided in the operation unit 30, or a predetermined operation in combination thereof may be set in advance as an input operation for canceling the start prohibition of the engine 28.

When the user performs a predetermined input operation for releasing the start prohibition of the engine 28 by the operation unit 30, the input determination unit 16 determines that the correct input operation has been performed (step S20: YES). In this case, the control unit 11 releases the start prohibition of the engine 28 (step S9), and stops the output to request the input operation for releasing the start prohibition of the engine 28 (step S21).

On the other hand, if the user does not perform a predetermined input operation by the operation unit 30, the input determination unit 16 determines that there is no correct input operation (step S20: NO). In this case, the output to request the input operation for releasing the start prohibition of the engine 28 is continued.

According to the third embodiment described above, since the start of the engine 28 is prohibited even if the reserved lock is not realized because the lock condition is not satisfied, a malicious third party starts the engine 28. It is not possible to prevent the vehicle 50 from being stolen. Further, after the start prohibition of the engine 28 is prohibited, the input request unit 15 outputs that the user is requested to perform an input operation for canceling the start prohibition of the engine 28. Then, by performing a predetermined input operation of the operation unit 30 that the user can know, the prohibition of starting the engine 28 can be easily released. On the other hand, a malicious third party who does not know the predetermined input operation cannot lift the start prohibition of the engine 28 and cannot start the engine 28, so that the theft of the vehicle 50 can be effectively prevented. It becomes possible.
