Therefore, the travel control device 3 is configured so that it cannot be confirmed at a glance that the vehicle 4 is equipped with the vehicle antitheft device 1 by being installed at a position that cannot be visually recognized from the appearance of the vehicle 4. Similarly, the speaker 7 is covered with a vehicle body cover 8 of the vehicle 4 and cannot be visually recognized on the appearance of the vehicle 4.

  The vehicle antitheft device 1 permits the travel control means 6 to start an engine (not shown) only when the travel control device 3 receives a confirmation signal by one-way communication with the portable transmitter 2. . Alternatively, when the vehicle theft countermeasure device 1 cannot receive the confirmation signal from the portable transmitter 2 after the engine is started, the travel control device 3 having an internal timer (not shown) as a measuring means measures the elapsed time. After a predetermined time has elapsed, an alarm sound is emitted from the speaker 7 for a predetermined time in order to inform the user that the confirmation signal from the portable transmitter 2 has not been received. Further, when the confirmation signal cannot be received even after a predetermined time has elapsed, the vehicle antitheft device 1 determines that the vehicle 4 has been stolen by the burglar and causes the vehicle 4 to stop. It is configured to be able to output to the travel control means 6 a control signal for interrupting the power to be supplied or performing control for suppressing the travel of the vehicle 4.

Based on the control signal, the code generator 18 encodes the confirmation signal to generate a code signal and outputs the code signal to the transmission unit 19. The transmission unit 19 transmits the code signal by a radio wave having a specific frequency. The portable transmitter 2 is configured to repeatedly transmit the confirmation signal and continuously transmit the confirmation signal to the travel control device 3 as long as electricity is supplied from the battery 17.

(2-2) Travel Control Device The travel control device 3 has a power supply unit 23, a reception unit 24, a blinker relay unit 25, and a vehicle as vehicle information acquisition means for the control unit 22 provided in the control device main body 21. An information acquisition interface 26 and a power cut-off unit 27 are connected to each other. A battery 30, an ignition switch 31, and a ground G are connected to the power supply unit 23, and a right winker 32R and a left winker 32L are connected to the winker relay unit 25. The vehicle information acquisition interface 26 provides necessary information to the vehicle 4 side in order to detect the state of the vehicle 4, that is, whether the vehicle 4 is running or stopped, or whether the vehicle 4 is stopping. The vehicle information detection means 33 acquired from is connected. The power interrupting unit 27 is connected to a traveling control means 6 that electrically controls the traveling of the vehicle 4. A speaker 7 provided in the vehicle 4 is connected to the control unit 22.

  The vehicle information acquisition interface 26 includes an analog signal interface 40 and / or a digital signal interface 41, and a detection signal that is an output of the vehicle information detection means 33 according to the form of the signal output from the vehicle information detection means 33 Can be converted into a vehicle information signal and output to the control unit 22.

  Incidentally, the analog signal interface 40 is configured by connecting resistors, capacitors, Zener diodes, and bipolar transistors as shown in FIG. The digital signal interface 41 is configured by connecting diodes, resistors, capacitors, Zener diodes, and bipolar transistors as shown in FIG.

  The power cut-off unit 27 includes a device power supply cut-off circuit 42 and a device control cut-off circuit 43, and can select one of the circuits according to the form of the travel control means 6 described later. Incidentally, the device power supply cutoff circuit 42 is configured by connecting a resistor, a capacitor, a bipolar transistor, and a Zener diode as shown in FIG. In order to cut off the current, a resistor, a bipolar transistor, and an FET transistor are connected as shown in FIG. The device control cutoff circuit 43 is configured by connecting resistors, bipolar transistors, and relays as shown in the figure. With the above configuration, the power cut-off unit 27 cuts off the electric power supplied to the travel control unit 6 based on the travel control signal from the control unit 22.

  Various vehicle information detection means 33 are conceivable. For example, as shown in FIG. 3, a brake detection unit 50, a neutral detection unit 51, a clutch detection unit 52, a vehicle speed pulse detection unit 53, and a rotation pulse detection unit 54 The ignition pulse detection unit 55 and the acceleration detection unit 56 are configured.

  Various types of travel control means 6 are conceivable. For example, as shown in FIG. 4, an ignition coil and spark plug 60, an ignition unit 61, a fuel control unit 62, a fuel valve 63, a throttle valve control device 64, a generator 65, transmission 66, brake 67, and battery 30.

  In this case, the control unit 22 includes various types such as a CPU (Central Processing Unit), a RAM (Random Access Memory), a basic program, a warning processing program, a security processing program, an alarm processing program, a traveling processing program, and a traveling control processing program (not shown). The program is composed of a ROM (Read Only Memory) in which a program is stored in advance.

  Then, the control unit 22 appropriately reads out various programs such as a basic program from the ROM in accordance with the presence or absence of a confirmation signal from the receiving unit 24 and develops it on the RAM, thereby supervising the entire traveling control device 3 according to these various programs. Are controlled to realize various functions.

  In the travel control device 3 (FIG. 2), when an ignition key (not shown) is inserted into a key cylinder (not shown), the power supply unit 23 generates an ignition information signal and outputs the ignition information signal to the control unit 22. The control unit 22 determines that the ignition switch 31 is turned on when the ignition information signal is input.

  In addition, the traveling control device 3 receives the code signal transmitted from the portable transmitter 2 when the receiver 24 is turned on when the ignition switch 31 that is turned on and off in conjunction with the insertion and rotation of the ignition key is turned on. Is always maintained in a state where it can be received. When receiving the code signal, the receiving unit 24 determines whether the code signal is a code signal addressed to itself, generates only a code signal addressed to itself, generates a confirmation signal, and outputs the confirmation signal to the control unit 22 To do.

  Actually, the control unit 22 determines whether or not the operator is an authorized user of the vehicle 4 based on the confirmation signal from the portable transmitter 2 when the ignition information signal is obtained while the vehicle 4 is stopped. To do. When the confirmation signal cannot be received, the control unit 22 generates a confirmation signal non-delivery signal after a predetermined time has elapsed and emits an alarm sound from the speaker 7 to notify the user.

  Further, when the ignition information signal is obtained while the vehicle 4 is stopped, the control unit 22 permits the engine start only when the confirmation signal is received, that is, when it can be determined that the vehicle is an authorized user. A signal is generated and output to the power cut-off unit 27. Thus, the engine can be started without being affected by the power cut-off unit 27. The vehicle antitheft device 1 is configured so that the engine cannot be started unless the power cut-off unit 27 acquires an engine start permission signal.

  In addition, when the confirmation signal is interrupted after the engine is started, the control unit 22 generates a first alarm sound generation signal after a predetermined time has elapsed, generates a first alarm sound from the speaker 7, and prompts the user. It notifies that the confirmation signal has been interrupted. As a result, the vehicle antitheft device 1 sends a confirmation signal to a legitimate user who is operating the vehicle 4 without noticing that the battery 30 of the portable transmitter 2 is dead, broken, or dropped. Can no longer be received.

  Incidentally, at this time, the control unit 22 can also output a blinker blinking signal to the blinker relay unit 25 to blink the blinkers 32R and 32L. Thus, blinking the blinkers 32R and 32L together with the first alarm sound can visually notify the user.

  The vehicle information detection means 33 outputs the detection signal acquired from the vehicle 4 to the vehicle information acquisition interface 26. Actually, the brake detection unit 50 as the vehicle information detection means 33 outputs a brake detection signal to the vehicle information acquisition interface 26 when the user operates the brake 67 while holding a brake lever (not shown).

  Further, the neutral detection unit 51 as the vehicle information detection means 33 outputs a neutral detection signal to the vehicle information acquisition interface 26 when the transmission 66 is in a neutral state.

  Further, the clutch detection unit 52 as the vehicle information detection means 33 outputs a clutch detection signal to the vehicle information acquisition interface 26 when the clutch (not shown) is disconnected. Incidentally, the clutch detection unit 52 can be configured by connecting a neutral switch 70, a clutch switch 71, a lamp 72, and a starter control circuit 73 together with the neutral detection unit 51, as shown in FIG. In this way, the vehicle 4 is configured such that when the transmission 66 is in a position other than neutral (when the neutral switch 70 is off), the engine can be started only when the clutch is disengaged (clutch switch 71 is turned on). Has been.

  Further, the vehicle speed pulse detection unit 53 as the vehicle information detection means 33 (FIG. 2) outputs the vehicle speed pulse of the vehicle 4 to the vehicle information acquisition interface 26 as a vehicle speed detection signal. Therefore, only the vehicle speed pulse detection unit 53 needs to be provided to determine whether the vehicle 4 is running or stopped. That is, the vehicle antitheft device 1 measures the vehicle speed based on the vehicle speed detection signal obtained from the vehicle speed pulse detection unit 53, and when the vehicle speed is zero, that is, when the vehicle speed pulse signal output is zero, the vehicle 4 is It can be determined that it has stopped.

  The rotation pulse detector 54 as the vehicle information detection means 33 outputs the engine rotation pulse to the vehicle information acquisition interface 26 as a rotation detection signal. Incidentally, the engine is kept below a certain number of revolutions in the idling state. Therefore, the vehicle antitheft device 1 can determine that the vehicle 4 is stopped after a predetermined time has elapsed in the idling state.

  Further, the ignition pulse detection unit 55 as the vehicle information detection means 33 outputs an ignition pulse accompanying ignition of the ignition plug to the vehicle information acquisition interface 26 as an ignition detection signal. The ignition pulse is synchronized with the engine speed.

  Further, the acceleration detection unit 56 as the vehicle information detection means 33 is applied to the vehicle 4 when the vehicle 4 is accelerated or decelerated, or when some vibration is applied such as trying to carry the vehicle 4 with a heavy machine or the like. The generated acceleration is output to the vehicle information acquisition interface 26 as an acceleration detection signal. Therefore, the vehicle antitheft device 1 detects the state in which the vehicle 4 is decelerating, that is, the stopping operation of the vehicle 4, by using the acceleration detection unit 56 together with other detection units such as the brake detection unit 50. Can do.

  The vehicle information acquisition interface 26 that has acquired the detection signal from the vehicle information detection means 33 as described above converts each detection signal into a vehicle information signal and outputs it to the control unit 22. Actually, the vehicle information acquisition interface 26 uses a brake detection signal, neutral detection signal, clutch detection signal, vehicle speed detection signal, rotation detection signal, ignition detection signal, acceleration as a detection signal input from the vehicle information detection means 33. The detection signals are each converted into a brake information signal, a neutral information signal, a clutch information signal, a vehicle speed information signal, a rotation information signal, an ignition information signal, and an acceleration information signal as vehicle information signals and output to the control unit 22.

  The control unit 22 monitors the vehicle information signal input from the vehicle information acquisition interface when a predetermined time has passed after the engine is started and the confirmation signal is interrupted, or the vehicle 4 is stopped or It is determined whether the vehicle 4 is stopping. When it can be determined that the vehicle 4 is stopped, the control unit 22 generates a travel control signal and outputs it to the power cut-off unit 27.

  Further, when a predetermined time has passed after the engine is started and the confirmation signal is interrupted, the control unit 22 generates a second alarm sound generation signal and generates a second alarm sound from the speaker 7. The second warning sound is selected to be louder than the first warning sound, and informs that the vehicle 4 is stolen in the vicinity.

  The power cut-off unit 27 cuts off power to be supplied to the travel control unit 6 based on the travel control signal input from the control unit 22. The traveling control means 6 stops the vehicle 4 by stopping or decelerating the engine when the power to be supplied is cut off. Further, the control unit 22 intermittently outputs the traveling control signal according to a program stored in advance, thereby intermittently cutting off the power supplied to the traveling control means 6 or attenuating the movement of the engine or the like. It is also possible to gradually reduce the engine output or the speed of the vehicle 4 by outputting a travel control signal such as. In this way, the engine output or the speed of the vehicle 4 is gradually reduced to decelerate, and the vehicle 4 is brought to a stop.

  Actually, the ignition coil and the spark plug 60 as the travel control means 6 are misfired when power is cut off based on the travel control signal. Thereby, the vehicle antitheft device 1 can stop the engine. In the ignition coil, power supplied on the primary side of the ignition coil is cut off. By cutting off the electric power on the primary side, the circuit for cutting off the electric power can be miniaturized and the cost can be reduced.

  Further, the ignition unit 61 as the travel control means 6 stops the output operation to the spark plug or misfires the spark plug by cutting off the electric power based on the travel control signal. In this way, the vehicle antitheft device 1 can stop the engine or reduce the engine output and stop the vehicle 4. Further, by performing retard control, the ignition timing of the engine can be instantaneously retarded to reduce the engine output, and the vehicle 4 can be stopped.

  Further, the fuel control unit 62 as the traveling control means 6 stops the fuel supply operation by cutting off the electric power based on the traveling control signal. In this way, the vehicle antitheft device 1 can stop the vehicle 4 by stopping the engine, and when the power is cut off, the mixture of fuel and air is supplied to the cylinder. The fuel is diluted by reducing the pressure or changing the mixture ratio (A / F value) of the air-fuel mixture. In this manner, the vehicle antitheft device 1 can bring the vehicle 4 to a stop by reducing the fuel supplied to the engine and reducing the engine output.

  Further, the fuel valve 63 serving as the travel control means 6 closes the valve and shuts off the supply of fuel by reducing the power based on the travel control signal, or reduces the fuel supplied by restricting the valve. . In this manner, the vehicle antitheft device 1 can stop or reduce the fuel supplied to the engine, thereby stopping the engine or reducing the engine output, thereby causing the vehicle 4 to stop.

  Further, the throttle valve control device 64 serving as the travel control means 6 has a throttle valve (not shown) regardless of the opening of the accelerator (not shown) of the vehicle 4 by cutting off the electric power based on the travel control signal. Will not open. Thus, the vehicle antitheft device 1 can reduce the amount of air passing through the carburetor, reduce the engine output, and bring the vehicle 4 to a stop.

  Further, the generator 65 as the travel control means 6 stops power generation based on the travel control signal. As a result, the vehicle antitheft device 1 is no longer charged with the battery 30, the charge amount of the battery 30 gradually decreases, and the vehicle 4 cannot travel for a long time, and the vehicle 4 can be stopped.

  Further, the transmission 66 as the travel control means 6 disconnects the power transmission system based on the travel control signal. In this way, the vehicle antitheft device 1 decelerates the vehicle 4 to stop. Alternatively, the shift change is prohibited by locking the shift lever when the power is cut off or by releasing the connection between the shift lever and the transmission 66. Thereby, the vehicle antitheft device 1 decreases the speed of the vehicle 4 and stops the vehicle 4. In addition, the vehicle antitheft device 1 can also block the transmission 66 when the vehicle 4 is in a stopped state by shutting off the electric power to the transmission 66, and keep the vehicle 4 in a stopped state.

Further, the brake 67 as the travel control means 6 holds the brake 67 in a state where the brake lever is operated, that is, in a state where the brake 67 is applied, by cutting off electric power based on the travel control signal. Thus, the vehicle antitheft device 1 can stop the vehicle 4 by continuing to decelerate.
Further, the battery 30 as the travel control means 6 cuts off the power supplied to the travel control means 6 based on the travel control signal. Thereby, the vehicle antitheft device 1 can stop the engine and bring the vehicle 4 to a stop.

(3) Anti-Theft Processing Next, anti-theft processing in the vehicle anti-theft device 1 in a state where power is turned on will be described with reference to the flowcharts of FIGS.

(3-1) Standby State First, processing in the vehicle antitheft device 1 when the ignition switch 31 is off (standby state) will be described with reference to the flowchart of FIG.

  When the control unit 22 and the battery 30 are connected (routine RT1), the control unit 22 proceeds to step SP1. In step SP1, the control unit 22 performs initialization as an initial setting. Incidentally, this processing has already been performed at the time of delivery of the vehicle 4. Then, the control unit 22 proceeds to the next step SP2.

  In step SP2, the control unit 22 determines whether the ignition switch 31 of the vehicle 4 is turned on. If a negative result is obtained here, this means that the ignition switch 31 is OFF, that is, the vehicle 4 is maintained in a stopped state. At this time, the control unit 22 goes to the subroutine SR1. Move.

  In the subroutine SR1, the control unit 22 performs a warning process. Incidentally, the warning process may be originally provided in the vehicle 4, for example, when a vibration is applied to the stopped vehicle 4, an alarm is sounded, or the blinkers 32R and 32L are blinked. In addition to threatening burglars, it also notifies surrounding users and authorized users. Then, the control unit 22 repeats the above processing until the ignition switch 31 is turned on while continuously monitoring the ignition switch 31.

  On the other hand, if an affirmative result is obtained in step SP2, this indicates that the ignition switch 31 is on, that is, the operation of the vehicle 4 is about to start. Move to subroutine SR2.

(3-2) Security Processing Next, security processing in the vehicle theft countermeasure device 1 in a state where the ignition switch 31 of the stopped vehicle 4 is turned on will be described with reference to the flowchart of FIG.

  The controller 22 enters from the start step of the subroutine SR2 and proceeds to step SP4. In step SP4, the control unit 22 starts an internal timer to start countdown, and proceeds to the next step SP5. Incidentally, the control unit 22 inputs 12 [sec] to the internal timer.

  In step SP5, the control unit 22 determines whether or not the ignition switch 31 is turned on. If a negative result is obtained here, this means that the ignition switch 31 is off, that is, the user has stopped the operation of the vehicle 4 and has returned the vehicle 4 to the stop state. Moves to step SP10.

  In step SP10, the control unit 22 resets the internal timer and proceeds to a warning process of the subroutine SR1.

  On the other hand, if a positive result is obtained in step SP5, this indicates that the ignition switch 31 is on, that is, the user continues to operate the vehicle 4. At this time, the control unit 22 The process proceeds to step SP6.

  In step SP6, the control unit 22 determines whether or not a predetermined time has elapsed by counting down the internal timer. If a negative result is obtained here, this indicates that the predetermined time has not elapsed, and at this time, the control unit 22 proceeds to step SP8.

  In step SP8, the control unit 22 determines whether or not a confirmation signal has been received. If a negative result is obtained here, this means that the confirmation signal has not been received, that is, the portable transmitter 2 is not within a certain range around the vehicle 4 or the portable transmitter 2 is turned off. This indicates that the confirmation signal has not been reached due to a problem such as the above. At this time, the control unit 22 returns to step SP5 and repeats the above processing until a predetermined time has elapsed.

  On the other hand, if a positive result is obtained in step SP8, this indicates that the confirmation signal has been received, that is, the portable transmitter 2 is within a certain range around the vehicle 4, and at this time, the control unit 22 Is recognized as an operation by a regular user, and the process proceeds to the next subroutine SS2.

  On the other hand, if a positive result is obtained in step SP6, this indicates that a predetermined time has elapsed, that is, the user's intention to start the engine is continuing. At this time, the control unit 22 proceeds to step SP7. Move.

In step SP7, the control unit 22 resets the internal timer and proceeds to alarm processing in step SP8.
(3-2-1) Alarm Processing Next, in the vehicle antitheft device 1, alarm processing when the ignition switch 31 is turned on for a predetermined time without receiving a confirmation signal will be described with reference to the flowchart of FIG. explain.

  The control unit 22 enters from the start step of the subroutine SS1 and proceeds to step SP20. In step SP20, the control unit 22 generates a confirmation signal non-delivery signal indicating that the confirmation signal from the portable transmitter 2 is in a non-delivery state, emits an alarm sound from the speaker 7, and notifies the user. The process proceeds to step SP21.

  In step SP21, the control unit 22 starts an internal timer to start countdown, and proceeds to the next step SP22. Incidentally, the control unit 22 inputs 5 [min] as the longest sound emission time of the alarm sound to the internal timer.

  In step SP22, the control unit 22 determines whether or not a confirmation signal from the portable transmitter 2 has been received. If an affirmative result is obtained here, this means that the confirmation signal has been received, that is, the portable transmitter 2 is located within a certain range from the vehicle 4, or the malfunction of the portable transmitter 2 is resolved and normal. In this case, the control unit 22 proceeds to SP23.

  In step SP23, the control unit 22 generates an alarm sound stop signal, stops the alarm sound, recognizes that it is an operation by a regular user, and proceeds to the traveling process of the subroutine SS2.

  On the other hand, if a negative result is obtained in step SP22, this indicates that the confirmation signal has not been received. At this time, the control unit 22 proceeds to the next step SP24.

  In step SP24, the control unit 22 determines whether or not the ignition switch 31 is turned on. If a negative result is obtained here, this means that the ignition switch 31 is off, that is, that the user has given up starting the engine and the vehicle 4 has been stopped. Moves to the next step SP25.

  In step SP25, the control unit 22 generates an alarm sound stop signal, stops the alarm sound, and proceeds to a warning process of the subroutine SR1.

  On the other hand, if a positive result is obtained in step SP24, this means that the ignition switch 31 is on, that is, the user is trying to start the engine even though the confirmation signal is undelivered. In this case, the control unit 22 proceeds to the next step SP26.

  In step SP26, the control unit 22 determines whether or not a predetermined time has elapsed by counting down the internal timer. If a negative result is obtained here, this means that the predetermined time has not elapsed. At this time, the control unit 22 returns to step SP22 and repeats the above determination until the predetermined time has elapsed.

  On the other hand, if a positive result is obtained in step SP26, this indicates that a predetermined time has elapsed since the start of alarm sound emission, and at this time, the control unit 22 proceeds to step SP27.

  In step SP27, the control unit 22 generates an alarm sound stop signal, stops the alarm sound, and proceeds to the next step SP28.

  As described above, the user can appropriately respond to the user by monitoring the confirmation signal and the ignition switch 31 while emitting an alarm sound for a predetermined time and notifying the user that the confirmation signal has not been reached. A time margin can be given.

  In step SP28, the control unit 22 resets the internal timer, and proceeds to the next step SP29.

  In step SP29, the control unit 22 determines whether or not a confirmation signal from the portable transmitter 2 has been received. If an affirmative result is obtained here, this means that the confirmation signal has been received, that is, the portable transmitter 2 is located within a certain range from the vehicle 4, or the malfunction of the portable transmitter 2 is resolved and normal. In this case, the control unit 22 recognizes that it is an operation by a regular user, and proceeds to the traveling process of the subroutine SS2.

  On the other hand, if a negative result is obtained in step SP29, this indicates that the confirmation signal has not been received. At this time, the control unit 22 proceeds to step SP30.

  In step SP30, the control unit 22 determines whether or not the ignition switch 31 is turned on. If a negative result is obtained here, this means that the ignition switch 31 is OFF, that is, the user has given up starting the engine and the vehicle 4 has been stopped. In 22, the process proceeds to a warning process of the subroutine SR1.

  On the other hand, if an affirmative result is obtained in step SP30, this means that the user tries to start the engine even though the ignition switch 31 is on, that is, the confirmation signal is undelivered. At this time, the control unit 22 returns to step SP29 and repeatedly monitors until confirmation of receipt of a confirmation signal or turning off of the ignition switch 31 is confirmed.

(3-2-2) Traveling Process Next, the traveling process in the vehicle antitheft device 1 will be described with reference to the flowcharts of FIGS. The travel process is started when the vehicle antitheft device 1 can recognize that a user who is recognized as a regular user is about to start the engine by receiving a confirmation signal.

  The control unit 22 enters from the start step of the subroutine SS2 and proceeds to step SP38. In step SP38, the control unit 22 generates an engine start permission signal, outputs it to the power cut-off unit, and proceeds to the next step SP39. Actually, when the ignition key is operated, the vehicle 4 starts the engine without being restricted by the power cut-off unit.

  In step SP39, the control unit 22 starts an internal timer to start countdown, and proceeds to the next step SP40.

  Incidentally, the control unit 22 inputs 100 [sec] to the internal timer. The time input to this timer is a time during which normal running is possible after the engine is started regardless of the user. In this way, any user can run the vehicle 4 after the engine is started, so that when the vehicle 4 is stolen, the time and distance allowance for leaving the robber who took the vehicle 4 is removed. It can be given to regular users.

  In step SP40, the control unit 22 determines whether or not a confirmation signal has been received. If an affirmative result is obtained here, this indicates that a confirmation signal has been received, that is, an operation by a legitimate user. At this time, the control unit 22 proceeds to step SP41.

  In step SP41, the control unit 22 resets the internal timer, and proceeds to the next step SP42.

  In step SP42, the control unit 22 determines whether or not the ignition switch 31 is turned on. If a positive result is obtained here, this means that the ignition switch 31 is on, that is, that the authorized user continues to operate the vehicle 4, and at this time, the control unit 22 returns to step SP39. , Continue to monitor the confirmation signal, the on / off of the ignition switch 31.

  On the other hand, if a negative result is obtained in step 42, this means that the ignition switch 31 is OFF, that is, that the authorized user has stopped driving and the vehicle 4 has been stopped. The unit 22 proceeds to a warning process of the subroutine SR1.

  On the other hand, if a negative result is obtained in step SP40, this means that the confirmation signal has not been received, that is, the vehicle 4 is being operated in a state where the confirmation signal has been interrupted. Move to SP43.

  In step 43, the control unit 22 determines whether or not the ignition switch 31 is turned on. If a negative result is obtained here, this means that the ignition switch 31 is off, that is, that the confirmation signal is not reached for some reason, and the user has stopped driving the vehicle 4, and this At this time, the control unit 22 proceeds to a warning process of the subroutine SR1.

  On the other hand, if an affirmative result is obtained in step SP43, this indicates that the ignition switch 31 is on, that is, the vehicle 4 continues to run despite the confirmation signal not being reached. At this time, the control unit 22 proceeds to step SP44.

  In step SP44, the control unit 22 determines whether or not a predetermined time has elapsed by counting down the internal timer. If a negative result is obtained here, this means that the predetermined time has not elapsed. At this time, the control unit 22 returns to step SP40 and repeats the above determination until the predetermined time has elapsed.

  On the other hand, if an affirmative result is obtained in step 44, this means that the predetermined time has elapsed, that is, the confirmation signal has not been reached and the vehicle 4 is continuously running for the predetermined time. At this time, the controller 22 proceeds to step SP45.

  In step SP45, the control unit 22 resets the internal timer, and proceeds to the next step SP46.

(3-2-3) Warning driving state Although the vehicle antitheft device 1 is traveling in a state in which the confirmation signal cannot be received by the above processing, it is assumed that the user is a regular user. The state shifts to a warning driving state informing that the vehicle is traveling in a state where the confirmation signal cannot be received.

  By the way, in this warning driving state, it is considered that the user who is driving the vehicle 4 is an authorized user, such as dropping the portable transmitter 2 or turning off the power of the portable transmitter 2. The case where the legitimate user is not aware that the confirmation signal is undelivered due to the occurrence of the problem is causing the vehicle 4 to travel.

  In step SP46, the control unit 22 generates a first warning sound generation signal indicating that the vehicle travels in a state where the confirmation signal does not reach, and emits an alarm sound from the speaker 7 to notify the user, Move to SP47.

  In step SP47, the control unit 22 starts an internal timer to start countdown, and proceeds to the next step SP48. Incidentally, the control unit 22 inputs 30 [sec] as the longest sound emission time of the first alarm sound to the internal timer.

  In step SP48, the control unit 22 determines whether or not a confirmation signal has been received. If an affirmative result is obtained here, this means that an authorized user who has received the confirmation signal, that is, that he / she is traveling in a state where the confirmation signal has not reached, puts the portable transmitter 2 in a normal state. This indicates that a return confirmation signal can be transmitted. At this time, the control unit 22 proceeds to step SP49.

  In step SP49, the control unit 22 generates a first warning sound stop signal, stops the first warning sound, and returns to step SP39.

  On the other hand, if a negative result is obtained in step SP48, this means that the confirmation signal has not been received, that is, the vehicle 4 is continuously running in a state where the confirmation signal is interrupted, and at this time, the control unit 22 moves to step SP50.

  In step SP50, the control unit 22 determines whether or not the ignition switch 31 is turned on. If an affirmative result is obtained here, this means that the ignition switch 31 is on, that is, the vehicle 4 is continuously driven even though the confirmation signal has not been reached. The unit 22 moves to step SP51.

  In step SP51, the control unit 22 determines whether or not a predetermined time has elapsed by counting down the internal timer. If a negative result is obtained here, this means that the predetermined time has not elapsed. At this time, the control unit 22 returns to step SP48 and repeats the above determination until the predetermined time has elapsed.

  On the other hand, if an affirmative result is obtained in step SP51, this means that a predetermined time has elapsed, that is, the confirmation signal has not been reached and the vehicle 4 continues to travel for a predetermined time. It is determined that the driving of the vehicle 4 is a burglar, and at this time, the control unit 22 proceeds to step SP52.

  In step SP52, the control unit 22 generates a first warning sound stop signal, stops the first warning sound, and proceeds to the next step SP53.

  In step SP53, the control unit 22 resets the internal timer, and proceeds to the next step SP55.

  On the other hand, if a negative result is obtained in step SP50, this means that the ignition switch 31 is off, that is, the user notices that the confirmation signal is not reached for some reason due to the first alarm sound and travels. This indicates that the vehicle has been stopped and the vehicle 4 has been stopped. At this time, the control unit 22 proceeds to step SP54.

  In step SP54, the control unit 22 generates a first warning sound stop signal, stops the first warning sound, and proceeds to a warning process of subroutine SR1.

(3-2-4) Travel Control State By the above processing, the vehicle antitheft device 1 ignores the first alarm sound and continues to travel, so that the vehicle 4 is stolen by a burglar and It is determined that the vehicle 4 and the burglar are at a distance sufficiently away from the user, and a transition is made to a travel control state in which the vehicle is brought to a stop.

  In step SP55, the control unit 22 generates a second alarm sound generation signal, emits the second alarm sound from the speaker 7, and proceeds to the next step SP56.

  In step 56, the control unit 22 starts an internal timer to start counting down, and proceeds to the next step SP57. Incidentally, the control unit 22 inputs 5 [min] as the longest sound emission time of the second alarm sound to the internal timer.

  In step 57, the control unit 22 determines whether or not a confirmation signal has been received. If an affirmative result is obtained here, this indicates that a confirmation signal has been received. At this time, the control unit 22 proceeds to step SP58.

  In step SP58, the control unit 22 generates a second warning sound stop signal, stops the second warning sound, and returns to step SP39.

  On the other hand, if a negative result is obtained in step SP57, this indicates that the confirmation confirmation signal has not been received. At this time, the control unit 22 proceeds to step SP59.

  In step SP59, the control unit 22 determines whether or not the ignition switch 31 is turned on. If an affirmative result is obtained here, this means that the ignition switch 31 is on, that is, the vehicle 4 is continuously running even though the confirmation signal has not been reached. The section 22 moves to subroutine SS3.

  On the other hand, if a negative result is obtained in step SP59, this indicates that the ignition switch 31 is off, that is, that the stolen vehicle 4 has been put in a stopped state. Control goes to step SP60.

  In step SP60, the control unit 22 generates a second warning sound stop signal, stops the second warning sound, and proceeds to a warning process of the subroutine SR1.

  In the subroutine SS3, the control unit 22 performs a travel control process to be described later. If the vehicle has not stopped due to the travel control process, the process proceeds to step SP61.

  In step SP61, the control unit 22 determines whether or not a predetermined time has elapsed by counting down the internal timer. If a negative result is obtained here, this means that the predetermined time has not elapsed. At this time, the control unit 22 returns to step SP57 and repeats the above determination until the predetermined time has elapsed.

  On the other hand, if a positive result is obtained in step SP61, this indicates that a predetermined time has elapsed from the start of sound emission of the second alarm sound, and at this time, the control unit 22 proceeds to step SP62.

  In step SP62, the control unit 22 generates a second warning sound stop signal, stops the second warning sound, and proceeds to the next step SP63. In step SP63, the control unit 22 resets the internal timer, and proceeds to the next step SP64.

  In step SP64, the control unit 22 determines whether or not a confirmation signal has been received. If an affirmative result is obtained here, this indicates that a confirmation signal has been received. At this time, the control unit 22 proceeds to step SP39.

  On the other hand, if a negative result is obtained in step SP64, this indicates that the confirmation signal has not been received. At this time, the control unit 22 proceeds to step SP65.

  In step SP65, the control unit 22 determines whether or not the ignition switch 31 is turned on. If an affirmative result is obtained here, this means that the ignition switch 31 is on, that is, the vehicle 4 is continuously running even though the confirmation signal has not been reached. The section 22 moves to subroutine SS3.

  On the other hand, if a negative result is obtained in step SP65, this means that the ignition switch 31 is off, that is, that the stolen vehicle 4 has been placed in a stopped state. The process proceeds to the warning process of subroutine SR1.

  In the subroutine SS3, the control unit 22 performs a travel control process to be described later. If the vehicle has not stopped due to the travel control process, the process proceeds to step SP66.

  In step SP66, the control unit 22 determines whether or not the vehicle 4 is traveling by the acceleration detection unit 56. If an affirmative result is obtained here, that is, when an acceleration information signal is acquired from the acceleration detection unit 56 via the vehicle information acquisition interface, this indicates that the vehicle 4 continues to travel in a stolen state. The time control unit 22 returns to step SP55.

  On the other hand, if a negative result is obtained in step SP66, this indicates that the vehicle 4 is stopped, that is, that the vehicle 4 is left in a stopped state. At this time, the control unit 22 performs step SP64. Returning to FIG. 2, the presence / absence of a confirmation signal and the on / off of the ignition switch 31 are monitored. Further, when the vehicle 4 is not stopped, the vehicle 4 can be stopped by the traveling control process by the subroutine SS3.

(3-2-5) Travel Control Processing Next, travel control processing in the vehicle antitheft device 1 will be described with reference to the flowchart of FIG.

  The control unit 22 enters from the start step of the subroutine SS3 and proceeds to step SP70. In step SP70, the control unit 22 starts an internal timer to start countdown, and proceeds to the next step SP71. Incidentally, the control unit 22 inputs 3 [sec] to the internal timer. The time input to the internal timer is a time during which it can be determined that the stop operation of the vehicle 4 is reliable.

  In step SP71, the control unit 22 determines whether or not the vehicle 4 is stopping based on the vehicle information signal. Here, if a positive result is obtained, this indicates that the vehicle 4 is stopping, and at this time, the control unit 22 proceeds to step SP72.

  Actually, in step SP71, the control unit 22 acquires the neutral information signal and the brake information signal to determine whether the transmission 66 is in the neutral position and the brake 67 is operating. By doing so, the control unit 22 can reliably detect that the user is stopping to stop the vehicle 4 or that the vehicle 4 is stopped.

  On the other hand, if a negative result is obtained in step SP71, this means that the vehicle 4 is not stopping, that is, it is not a suitable timing for performing the traveling control on the vehicle 4, and the control is performed at this time. The part 22 moves to step SP73.

  In step SP73, the internal timer is reset, and the process proceeds to step SP61 or step SP66.

  In step SP72, the control unit 22 determines whether or not a predetermined time has elapsed by counting down the internal timer. If a negative result is obtained here, this means that the predetermined time has not elapsed, that is, it cannot be said that the stopping operation is reliable. At this time, the control unit 22 returns to step SP71, The above determination is repeated until a predetermined time has elapsed.

  On the other hand, if an affirmative result is obtained in step SP72, this indicates that the predetermined time has elapsed, that is, that the stopping operation of the vehicle 4 is reliable, and at this time, the control unit 22 performs the step. Move to SP74.

  In step SP74, the control unit 22 resets the internal timer, and proceeds to the next step SP75.

In step SP75, the control unit 22 generates a travel control signal, instructs the power cut-off unit 27 to perform a power cut-off operation, stops the engine, reduces the engine output, or decelerates the vehicle 4. Bring to a stop. Then, the control unit 22 returns to step SP22.
(4) Operation and Effect In the above configuration, the vehicle antitheft device 1 can travel within a predetermined time without receiving a confirmation signal after starting the engine.

  Thereby, in the vehicle antitheft device 1, when the vehicle 4 is stolen by a burglar, it is possible to give a legitimate user sufficient time and distance margin to leave the robber.

  Moreover, in the vehicle antitheft device 1, when it is determined that the vehicle 4 is in a stolen state, the vehicle 4 is stopped by detecting the state of the vehicle 4 by a predetermined method, or the vehicle 4 is Only when it is recognized that the stop operation is being performed reliably, the traveling control process for cutting off the power supply to the vehicle 4 is performed.

  Thus, only when it is recognized that the vehicle 4 is stopped or the vehicle 4 is surely performing the stop operation, the travel control process for cutting off the power supply to the vehicle 4 is performed. As a result, the vehicle 4 can be stopped normally and the influence on general traffic can be minimized. Therefore, even a user who is not familiar with the operation of the vehicle 4 is not confused by the traveling control process, so that the vehicle 4 can be prevented from being broken, and damage to the user can be minimized.

  Incidentally, in the vehicle antitheft device 1, the vehicle 4 is stopped by detecting that the transmission 66 is in the neutral state and the operation of the brake 67 is started based on the neutral information signal and the brake information signal. Can be reliably detected.

  Further, the vehicle antitheft device 1 can recognize the confirmation signal transmitted from the portable transmitter 2 by a specific radio wave, and informs the user of the result by a predetermined method.

  Thereby, in the vehicle antitheft device 1, when the portable transmitter 2 is not within a certain range with respect to the travel control device 3 mounted on the vehicle 4, by emitting a predetermined alarm sound from the speaker 7, It is possible to make the user easily recognize that the distance is so far that the radio wave from the portable transmitter 2 cannot be received or the power of the portable transmitter 2 is turned off. . Incidentally, the vehicle antitheft device 1 may blink the blinkers 32R and 32L in accordance with the notification by the alarm sound. Thereby, a user can be notified visually and can be recognized more easily.

  Further, the vehicle antitheft device 1 immediately performs a warning process when the ignition switch 31 is turned off. Thereby, secondary damage after the vehicle 4 is stolen can be prevented, and damage to the user can be further reduced.

  Further, in the vehicle antitheft device 1, the vehicle cannot be started unless the traveling control device 3 continuously receives the confirmation signal from the portable transmitter 2 for a predetermined time. The risk that 4 will be stolen can be reduced.

  Moreover, in the vehicle antitheft device 1, it is mounted on the back side of the tandem seat 5 of the vehicle 4 so that it cannot be recognized that the device is mounted in appearance, so that a thief can remove or cancel the setting. Can be made to function reliably.

  According to the above configuration, in the vehicle antitheft device 1 including the portable transmitter 2 that transmits the confirmation signal and the travel control device 3 that includes the receiving unit 24 that receives the confirmation signal, the travel control device 3 includes: An internal timer that measures the time from when the confirmation signal becomes unreceivable, and a power cut-off unit 27 that cuts off power to be supplied to the vehicle 4 based on the time measured by the internal timer. Thus, the engine is stopped after a predetermined time has elapsed since the confirmation signal cannot be received, so that it is possible to provide time and distance allowance for the legitimate user to sufficiently leave the stolen vehicle 4. It is possible to reduce damage to the authorized user.

  In addition, the travel control device 3 includes a travel distance measuring device that measures the distance traveled by the vehicle 4 from when the confirmation signal cannot be received, thereby confirming that the vehicle 4 has definitely left the authorized user. After confirming, the vehicle 4 can be stopped or traveling can be suppressed.

  In addition, the travel control device 3 includes a vehicle information acquisition interface 26 that acquires a detection signal for detecting the stop operation of the vehicle 4 from the vehicle information detection means 33 included in the vehicle 4, thereby stopping the vehicle 4. When the operation is detected, the power is cut off, so that the influence on general traffic can be reduced.

  In addition, the vehicle information acquisition interface 26 acquires the detection signal from a brake detection unit 50 that detects that the brake 67 is operating and a neutral detection unit 51 that detects that the transmission 66 is in a neutral state. As a result, the traveling control device 3 stops the engine when the brake 67 is operating and the trans-transmission 66 is in the neutral state, so that the vehicle 4 is properly stopped to affect the general traffic. Can be minimized.

  Further, in the travel control device 3 that receives the confirmation signal transmitted from the portable transmitter, the measurement means that measures the time or travel distance from when the confirmation signal becomes unreceivable, and the measurement means By providing a power cut-off unit 27 that cuts off the power to be supplied to the vehicle 4 based on time or travel distance, the vehicle traveled for a predetermined distance after a predetermined time has elapsed since the confirmation signal was not received. Since the vehicle 4 is brought to a stop later, the time and distance allowance for the legitimate user to be sufficiently separated from the stolen vehicle 4 can be provided, and damage to the legitimate user can be reduced.
