  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a conceptual diagram showing a communication system of an abnormality detection and vehicle tracking device (hereinafter also referred to as an abnormality detection device) according to an embodiment of the present invention. The motorcycle 1 is provided with an abnormality detection device 10 that detects an abnormal state of the vehicle and issues a warning. When a signal exceeding a predetermined value is output from an acceleration sensor or the like attached to the vehicle body while the vehicle is stopped, the abnormality detection device 10 determines that an abnormality has occurred in the vehicle, and the vehicle horn or lamp It is comprised so that a warning etc. may be actuated.

  The abnormality detection device 10 includes an in-vehicle telephone (see FIG. 2) that can communicate with the public telephone office 2. As a result, it is possible to make a call from the telephone 3 to the abnormality detection apparatus 10 via the public telephone station 2. The telephone 3 may be a mobile phone or a fixed telephone as long as it can access the public telephone station 2. In the present embodiment, GSM (Global System for Mobile Communications), which is a mobile phone standard, is applied to the communication standard of the in-vehicle telephone of the abnormality detection device 10, and calling the abnormality detection device 10 from the telephone 3 is not possible. This is possible in many countries that operate GSM.

  FIG. 2 is a block diagram illustrating a configuration of the abnormality detection apparatus 10 and its peripheral devices according to the present embodiment. The abnormality detection device 10 is, for example, a control device that is covered with a resin case of about 100 mm × 100 mm × 20 mm and does not have an operation means such as a switch, for example, a lower part of a motorcycle seat, a lower part of a fuel tank, etc. It is placed in a position where it is difficult for third parties to access. The abnormality detection device 10 includes a vehicle-mounted telephone 11 having a transmission / reception antenna 16 for communicating with the public telephone office 2, a communication control unit 12 that analyzes transmission / reception signals by the vehicle-mounted telephone 11, and failure detection of the abnormality detection device 10. Failure diagnosis means 14 for diagnosing presence / absence, display means 13 for displaying diagnosis results and the like by failure diagnosis means 14, and abnormal condition determination means 15 for determining an abnormal condition of the vehicle based on output signals from various sensors and the like. Including. The in-vehicle telephone 11 may be provided outside the abnormality detection device 10. Further, the communication control unit 12 can be set so as to deny access from other than a predetermined telephone registered in advance.

  Note that in order to perform wireless communication by the in-vehicle phone 11, the vehicle owner needs to make a communication contract with the provider 4. Whether or not to make a communication contract with the provider 4 can be arbitrarily selected by the owner of the vehicle. Even when the user does not have a communication contract with the provider 4, the abnormality detection device 10 can be used as a normal abnormality detection device that operates the warning means 40 based on vibrations applied to the vehicle body. Hereinafter, in the case where communication by the in-vehicle telephone 11 is performed, it is assumed that all have a communication contract with the provider 4.

  The abnormal state determination means 15 is for monitoring an acceleration sensor 30 as a vibration sensor for detecting vibrations applied to the vehicle body, a tilt sensor 31 for detecting the front / rear / left / right tilt angles of the vehicle body, access to the power supply circuit, and the like. An output signal from the voltage sensor 32 that detects a change in the battery voltage is input. For example, the abnormal state determination unit 15 determines that the vehicle is in an abnormal state when at least one output signal of various sensors exceeds a predetermined value. The abnormality detection device 10 is configured to be able to transmit to the telephone 3 such as a user via the in-vehicle telephone 11 that an abnormal condition has been detected. At this time, the time when the abnormal state is detected, the type of the activated sensor, and the like can be displayed on the display as the display means of the telephone 3.

  In addition, a GPS (Global Positioning System) 20 is connected to the abnormal state determination means 15. The GPS 20 is used for the operation of the in-vehicle navigation system during normal driving of the vehicle. However, in the abnormality detection device 10 according to the present embodiment, when an abnormality occurs, the current position of the vehicle and the movement from the occurrence of the abnormality are detected. It is configured such that it can be used for a vehicle tracking function for transmitting a history or the like to the telephone 3 or the like via the in-vehicle telephone 11.

  In addition, an EFI (electronic control fuel injection device) 21 as an engine control device connected to the abnormal state determination means 15 is configured to be able to stop its drive in response to a command from the abnormal state determination means 15. As a result, in the unlikely event of an abnormality, the EFI 21 can be automatically stopped so that the vehicle cannot travel. The stop of the EFI 21 can be arbitrarily executed by operating the telephone 3. Note that the engine control device controlled by a command from the abnormal state determination means 15 may be an ignition device for a spark plug, various actuators, or the like.

  The abnormality detection device 10 according to the present embodiment diagnoses whether or not the abnormality detection device 10 is functioning normally by the failure diagnosis means 14, that is, executes a self-failure diagnosis (diagnosis) of the abnormality detection device 10. Is possible. The failure diagnosis unit 14 can detect, for example, a state where it cannot be determined as abnormal even if various sensors output signals exceeding a predetermined value due to a malfunction of the abnormal state determination unit 15. Further, the failure diagnosing means 14 can diagnose a state in which output signals from various sensors are not normally input, failure of various sensors themselves, and the like. When such a failure is detected, the failure diagnosing unit 14 is set to display the type of failure, a countermeasure, and the like on the display unit 13.

  With the configuration as described above, a vehicle mechanic or the like can perform a failure diagnosis of the abnormality detection device 10 by calling the abnormality detection device 10 from the telephone 3 and know the diagnosis result by the display means 13. it can. Note that a light emitting diode (LED), a liquid crystal screen, or the like can be applied to the display means 13.

  FIG. 3 is a time chart showing a flow when executing the self-failure diagnosis process of the abnormality detection device 10 using the telephone 3. In step S10, when a vehicle mechanic or the like calls the abnormality detection device 10 from the telephone 3, the vehicle-mounted telephone 11 of the abnormality detection device 10 receives this in step S11. In the subsequent step S12, reception completion is displayed on the display means 13. Thereby, the maintenance person etc. can confirm visually that the telephone line was connected. The procedure for making a call in step S10 can be executed by dialing a telephone number unique to the vehicle-mounted telephone 11 from a fixed telephone, a mobile phone or the like.

  Next, in step S20, a diagnostic item number (for example, 1 to 5) is input to the telephone 3. This diagnosis item can be constituted by contents such as whether there is no short circuit in the constituent circuit of the abnormality detection apparatus 10 or whether various sensors are functioning normally. In the subsequent step S21, the input diagnostic item is received by the in-vehicle telephone 11, and in step S22, the input diagnostic item is displayed on the display means 13. In step S40, the display means 13 displays that a failure diagnosis is to be performed. In step S41, a failure diagnosis instruction signal for starting a failure diagnosis is output from the communication control unit 12, and the selected diagnosis item is displayed. The failure diagnosis unit 14 executes the failure diagnosis.

  As described above, according to the abnormality detection device 10 according to the present embodiment, a failure diagnosis of the abnormality detection device 10 can be performed by operating the telephone 3. Normally, if the abnormality detection device 10 is provided with a self-diagnosis function so that a dedicated device for performing failure diagnosis is not required, the failure diagnosis mode in which the function of the abnormality detection device is temporarily suspended from the normal abnormality detection mode state. However, according to the abnormality detection device 10 according to the present embodiment, there is no need to provide an input means that can be operated by a third party, so that an easy method can be used. A failure diagnosis of the abnormality detection device can be executed, and a high abnormality detection effect of the abnormality detection device can be maintained.

  FIG. 4 is a circuit diagram of the abnormality detection device and its peripheral devices according to the present embodiment. The same reference numerals as those described above denote the same or equivalent parts. In this circuit diagram, the connection relationship between the abnormality detection device 10 and the warning means 40 (horn and turn signal described later) is mainly shown. The CPU 50 as the central processing unit of the abnormality detection apparatus 10 includes abnormality determination means, failure diagnosis means, and the like as shown in FIG. In the present embodiment, an LED (light emitting diode) connected to the CPU 50 is used as the display unit 13.

  An internal power supply 66 is connected to the CPU 50. The internal power supply 66 is provided to operate various sensors even when the in-vehicle battery 63 is removed, to drive the warning means 40 based on an output signal of the sensor, or to enable communication by the in-vehicle telephone 11. ing. If the in-vehicle battery 63 is connected, the CPU 50 is driven by the electric power of the in-vehicle battery 63, and the internal power supply 66 is not used. In this normal time, the internal power supply 10 is maintained in a fully charged state by the power supplied from the in-vehicle battery 63, and is set to be switched to the use state only when the in-vehicle battery 63 is removed.

  The abnormality detection device 10 is provided with a plurality of input / output ports. From the input port 80, the electric power of the vehicle-mounted battery 63 is supplied through the main fuse 64. The input ports 81 and 82 are used for monitoring the operation state of the ignition switch 60 for connecting / disconnecting the main power supply of the vehicle and the stop lamp switch 61 for lighting the stop lamp 43.

  The motorcycle 1 is provided with a horn 41 that operates in accordance with the operation of the horn switch 62 and a blinker light 42 that blinks in accordance with the operation of the turn signal switch (not shown). The horn 41 and the blinker lamp 42 normally do not operate even if each switch is operated unless the ignition switch 60 is in the ON state. However, when an abnormal state is detected while the vehicle is stopped, the CPU 50 switches on the transistors 53 and 54 and drives the relays 70 and 72 via the output ports 83 and 84, thereby causing the horn 41 and the blinker lamp to turn on. 42 is operated as the warning means 40.

  Further, when an abnormal state of the vehicle is detected, the CPU 50 can drive the transistor 51 connected to the input / output port 85 to stop the EFI 21. Furthermore, it is possible to transmit the abnormal state of the vehicle to a predetermined telephone using the in-vehicle telephone 11 connected to the input / output port 86.

  The abnormality detection apparatus 10 according to the present embodiment is configured to use the check coupler 90 connected via the input port 87 when making a fault diagnosis by calling the telephone 3 from the telephone 3 to the in-vehicle telephone 11. Yes. The check coupler 90 is, for example, a small device composed of a male coupler having a switch. By connecting the male coupler to a female coupler connected to the input port 87, an input signal of the switch can be input to the CPU 50. It can be comprised so that it may become. Here, with reference to FIG. 5, the flow in the case of performing failure diagnosis using the check coupler 90 will be described.

  FIG. 5 is a time chart showing the flow of failure diagnosis when the check coupler 90 is used. The same reference numerals as those described above denote the same or equivalent parts. The present modification is characterized in that an authentication process for preventing access by a third party is performed by collating the password code input from the telephone 3 with the password code input from the check coupler 90. In this time chart, a series of authentication processes are set to be performed between step 22 (diagnostic item display) and step S40 (diagnosis execution display) shown in FIG.

  In step S30, the personal identification code is input to the telephone 3, and in step S31, the input personal identification code is received by the in-vehicle telephone 11. In the subsequent step S32, a password code is input by an on / off operation of the check coupler 90. In step S33, the abnormality detection device 10 authenticates the password. This authentication process is executed by the communication control unit 12 (see FIG. 2) of the abnormality detection apparatus 10.

  When the authentication process in step S33 is normally completed, in step S40, the display means 13 displays that the fault diagnosis is to be performed, and the fault diagnosis of the diagnostic item selected in step S41 is executed. It becomes. In other words, in the present embodiment, when the security code input from the telephone set 3 and the security code input from the check coupler 90 are different, the failure detection of the abnormality detection device is not performed, so that the failure is detected by a third party. It prevents the diagnosis from being performed. Note that the type of password code, the form of the check coupler, and the like can be variously modified. For example, the password code can be input by an operation of switching the connection state of the check coupler having no switch or the like.

  Returning to FIG. 4, the output ports 88 and 89 provided in the abnormality detection device 10 are provided for connection with various in-vehicle devices. The serial line 55 and K line (K-line) 56 connected to the CPU 50 can be arbitrarily switched to the output port 89 by a jumper select 57. The serial line 55 and the K line 56 are communication standards used for failure diagnosis of various in-vehicle devices. After connecting the in-vehicle device to the output port 89, a telephone call is made from the telephone 3 to the abnormality detection device 10 to diagnose the failure. Can be executed. The above-described EFI 21 can also be connected to the CPU 50 using this K line 56 and execute its failure diagnosis. Further, the type and number of input / output ports provided in the abnormality detection device 10 are not limited to the above-described embodiment, and various modifications are possible.

FIG. 6 is a block diagram showing the configuration of the operation mode switching means 17 in the abnormality detection device 10. The operation mode switching means 17 is provided in the CPU 50. The abnormality detection device 10 is provided with a total of eight types of operation modes, and the operation mode switching means 17 is configured to be able to switch between operation modes based on input information from various switches and the like. . There are eight operation modes as shown below.
1. Transportation mode (assuming transportation from factory to dealer. Internal power supply is prohibited and power consumption is reduced until the vehicle battery is connected)
2. Inspection mode (assuming the inspection of the abnormality detection device)
3. Wake-up mode (accepts switching operation to normal mode)
4). Normal mode (assuming normal use during driving, etc. Warning means will not be activated even if vibration applied to the vehicle is detected)
5). Refueling mode (assuming refueling by the user (ignition SW off). Warning means will not be activated even if vibration applied to the vehicle is detected)
6). Sleep mode (assuming normal ignition when the ignition switch is off. Warning means is activated when vibrations applied to the vehicle are detected)
7). Theft mode (assuming that the vehicle has been moved with the ignition key attached. The user recognizes that the vehicle is in an abnormal state by using the telephone, and activates the warning means)
8). Alarm theft mode (assuming that an abnormality has occurred with the ignition key removed. The warning means is activated and the user's telephone is notified)

  The operation mode switching means 17 includes a provider contract information input means 22 for inputting information on whether or not a communication contract is made with the provider 4, an ignition SW (switch) 60 for turning on / off the main power of the vehicle, a brake lever, The stop lamp SW (switch) 61 for detecting the operation of the brake pedal, the check coupler 90 described above, the theft mode release signal input means 23 for inputting the theft mode release signal transmitted from the user or the like, and the voltage value of the in-vehicle battery 63 are always set. Signals from the voltage sensor 32 to be monitored and the timer 27 to measure various predetermined times are input. The abnormality detection device 10 includes the internal power supply 66 and the voltage sensor 32, so that an alarm can be issued even when the in-vehicle battery 63 is removed in order to stop the function of the abnormality detection device 10.

  FIG. 7 is a state transition diagram showing the configuration of the operation mode switching control according to the present embodiment. The shipping state indicates a state where the in-vehicle battery 63 is not yet connected to the vehicle completed at the factory. The in-vehicle battery 63 is usually connected when the vehicle is handed over to the user after arriving at the store. In this shipping state, the operation mode of the abnormality detection device 10 is in the transportation mode M1. In the transportation mode M1, since it is not necessary to enable the abnormality detection function, the internal power supply 66 in a fully charged state is prohibited from being used, and the setting is made to suppress the consumption of the internal power supply 66 until the in-vehicle battery 63 is connected. Has been.

  Next, when the vehicle-mounted battery 63 is connected, the operation mode shifts to a wake-up mode M3 that accepts a switching operation to the normal mode M4. On the other hand, when the on-vehicle battery 63 is connected and the ignition switch (switch) 60 is turned on, the operation mode shifts to the inspection mode M2. This inspection mode M2 is set in order to execute an inspection or the like of the abnormality detection apparatus 10 in a factory or a store. Therefore, in the finished vehicle inspection at the factory, once the in-vehicle battery is connected and switched to the inspection mode M2, the system is inspected, the mode is switched to the transportation mode M1 after the inspection, the in-vehicle battery is disconnected, It will be transported to the dealer. As a result, the system can be inspected once the battery is connected, and the system will not malfunction when it is removed, so the in-vehicle battery can be removed, and the user can buy the vehicle. The in-vehicle battery is not discharged in the meantime, and the internal power supply is not consumed. For example, when the check coupler 90 is connected, the abnormality detection device 10 can be inspected by confirming whether the display unit (LED) 13 lights up as scheduled. In the inspection mode M2, when the ignition SW 60 is turned off and the in-vehicle battery 63 is removed, the mode returns to the transportation mode M1.

  Then, when a predetermined mode switching operation is performed in the wake-up mode M3, a transition is made to the normal mode M4 that is assumed for normal use by the user. In the normal mode M4, the acceleration sensor 30 and the inclination sensor 31 are operated, but the operation of the warning means 40 based on output signals from various sensors is prohibited. As a result, the warning means 40 does not operate during traveling or the like, and output signals from the acceleration sensor 30 and the inclination sensor 31 can be used for fuel injection control and ignition control.

  When the abnormality detection device 10 shifts to the normal mode M4, the abnormality detection device 10 checks whether or not the user has a communication contract with the predetermined provider 4. If the communication contract is made, the operation mode is shifted to the normal mode M8 with the provider contract. On the other hand, if the communication contract is not made, the operation mode is shifted to the normal mode M5 without the provider contract.

  In the normal mode M8 with a provider contract, when the ignition switch 60 of the vehicle is turned off and a predetermined time (for example, 1 minute) elapses, the operation mode shifts to the sleep mode M10. In the sleep mode M10, when vibration or the like is applied to the vehicle body and an abnormal state is detected, the process shifts to the alarm theft mode M11. In the alarm theft mode M11, it is assumed that an abnormal state occurs when the ignition key is removed from the vehicle body. At this time, the abnormality detection device 10 operates the warning means 40 and the vehicle is in an abnormal state. This can be notified to the user's mobile phone or personal computer.

  Further, when the user has accidentally shifted to the alarm theft mode M11, for example, when the user has shaken the vehicle body in the sleep mode M10, for example, the abnormality detection device 10 is used by using the user's telephone 3. It is possible to return to the sleep mode M10 by sending a sleep mode transition signal. When the ignition SW 60 is turned on in the sleep mode M10, the normal mode M8 with provider contract is returned.

  On the other hand, when refueling, there is a possibility that the ignition SW 60 is off and the user or the like shakes the vehicle body. Therefore, from the normal mode M8 with a provider contract, if the stop lever SW61 is turned on by operating the brake lever etc. and the ignition SW60 is turned off → on → off, various sensors detect vibrations and the like. Is set to shift to the fueling mode M12 in which the warning means 40 is not operated. When the ignition SW 60 is turned on in the fueling mode M12, the normal mode M8 with provider contract is returned.

  Further, there is a possibility that an abnormal state may be reached in a state where the ignition key is inserted, that is, in a state where the ignition SW 60 can be turned on by a third party. At this time, even if it is actually in an abnormal state, the abnormality detection device 10 does not activate the warning means 40 because a normal operation using the ignition key is performed. However, when a provider contract is made, for example, a user who has noticed an abnormality can call the abnormality detection device 10 from the telephone 3 or the like to cause the abnormality detection device 10 to recognize that it is in an abnormal state. it can.

  Thereby, the abnormality detection device 10 can operate the warning means 40 or stop the fuel injection device even when the vehicle in an abnormal state is traveling, for example. Further, the current position of the vehicle can be known by using the GPS function described above. If the user transmits a theft mode release signal by the telephone 3 or the like while in the theft mode M9, the mode returns to the normal mode M8 with a provider contract.

  Although the provider contracted operation has been described above, when the provider contract is not concluded, the remote operation of the abnormality detection device 10 by calling the in-vehicle telephone 11 or the position detection function by GPS is used. I can't. In the normal mode M5 without a provider contract, when the ignition SW 60 is turned off and a predetermined time (for example, 1 minute) elapses, the mode shifts to the sleep mode M7. In the sleep mode M7, when it is detected that vibration is applied to the vehicle body and an abnormal state is detected, only the warning means 40 is operated. If the ignition SW 60 is turned on while in the sleep mode M7, the normal mode M5 without the provider contract is returned.

  In addition, if the stop lamp SW61 is turned on by operating the brake lever or the like from the normal mode M5 without a provider contract, and the ignition SW60 is turned off, on, and turned off, a warning is issued even if various sensors detect vibration or the like. The operation proceeds to the oil supply mode M12 where the means 40 does not operate. In this fueling mode M6, when the ignition SW 60 is turned on, the normal mode M6 without provider contract is returned.

  The determination of the abnormal state in the abnormality detection device 10 according to the present embodiment is performed by the output signal of the voltage sensor 32 in addition to the acceleration sensor 30 and the inclination sensor 3. The voltage sensor 32 constantly monitors the voltage of the in-vehicle battery. For example, in the sleep mode M10, when the battery voltage suddenly decreases and becomes almost zero, an operation of removing the in-vehicle battery 63 from the vehicle body is performed. It is determined that it has been broken, and the operation shifts to the alarm theft mode M11. Note that the determination of the abnormal state based on the rapid decrease in the battery voltage is similarly performed in the sleep mode M7 that shifts from the normal mode M5 without the provider contract.

  By the way, in the abnormality detection apparatus 10 as described above, for example, if it is determined that the vibration exceeding a predetermined magnitude is input once and it is determined to be in an abnormal state, the passerby mistakenly detects the vehicle body. There is a possibility that the warning means 40 may be activated because it is determined as an abnormal state even if the user has touched or if the user moves the bicycle slightly at the bicycle parking lot. In order to prevent such erroneous detection, the abnormality detection device 10 according to the present embodiment is in an abnormal state only when a predetermined pattern consisting of a combination of the vibration detection interval and the number of detections is met. It is comprised so that it may determine. Hereinafter, a predetermined pattern for determining that the abnormal state determination means 15 is in an abnormal state will be described with reference to the time chart of FIG.

FIG. 8 is a time chart showing the relationship between vibration input to the vehicle body and abnormal state determination.
The abnormal state determination means 15 according to the present embodiment uses the output value of the timer 27 as a measurement means for measuring the vibration detection interval and the number of times of detection in addition to the detection value of the acceleration sensor 30 as a vibration sensor. It is characterized in that it prevents false detection of abnormal conditions.

  In this time chart, from the top, the ON / OFF state of the ignition SW 60, the voltage value of the in-vehicle battery 63, the usage state of the internal power supply 66, the operation mode of the abnormality detection device 10, and the permission to determine the abnormal state of the vibration detection value by the acceleration sensor 30 State, presence / absence of vibration applied to the vehicle body, operation state of alarm (horn 41) included in warning means 40, presence / absence of abnormality detection, communication state by in-vehicle phone 11, operation state of GPS 20, operation of GSM (in-vehicle phone) Indicates the state.

  When the ignition SW 25 is turned off at time t1, the operation mode shifts from the normal mode M8 with provider contract to the sleep mode M10 at time t2 after the time ΔtA (60 seconds in this embodiment) has elapsed, and vibration detection is performed. Use of the value to determine the abnormal state is permitted. Note that the GPS 20 and GSM are deactivated at time t1 when the ignition SW 25 is turned off. Further, when the communication contract with the provider 4 is not concluded, the GSM and the communication state are not turned on.

  In the present embodiment, at the time t2, the operation mode shifts to the sleep mode M10, and at the same time, the alarm set is notified to the user that the abnormality detection device 10 is functioning normally. It is configured to make a confirmation sound with a length of. Thereafter, when a vibration of a magnitude exceeding a predetermined value is applied to the vehicle body once, a warning sound is generated only for a very short time (for example, 5 seconds).

  In the present embodiment, a warning sound is sounded only for the time AL1 (for example, 5 seconds) with respect to the vibration applied at time t3. At this time, the abnormality detection device 10 does not determine that the abnormality is present. This is to call attention to the parked vehicle by issuing a short warning sound, although it is not judged abnormal when a single vibration is input, such as when a passerby contacts This is because it is set as follows.

  In the present embodiment, the second vibration input is performed at time t4 when the time ΔtB has elapsed from time t3 when the first vibration input was performed. The abnormality detection device 10 sounds a warning sound only during the time AL1 at this time t4. The third vibration input is performed at time t5 when time ΔtC has elapsed from time t4 when the second vibration input was made. Similarly, a warning sound for calling attention is sounded only during the time AL1.

  However, when the fourth vibration input is performed at time t6 when the time tD has elapsed from the time t5 when the third vibration input was made, the abnormal state determination means 15 (see FIG. 2) indicates that the vehicle is in an abnormal state. And the operation mode of the abnormality detection device 10 is shifted from the sleep mode M10 to the alarm theft mode M11.

  The abnormality detection device 10 is configured to store a plurality of predetermined vibration input patterns and to store a vibration input history (detection interval and number of detections) for a predetermined time. In the example of FIG. 8, “after a vibration having a magnitude greater than or equal to a predetermined value is first detected, a vibration having a magnitude greater than or equal to a predetermined value is detected once within 5 minutes. ”Is set to be determined to be in an abnormal state, and the times ΔtB, ΔtC, and ΔtD were within 5 minutes, respectively, and therefore, an abnormal state was determined at time t6.

  The predetermined vibration input pattern is: “After a vibration having a magnitude greater than or equal to a predetermined value is first detected, a vibration having a magnitude greater than or equal to a predetermined value is detected once within 5 to 10 minutes. It is possible to set the case where “repetition is repeated twice” or “when vibration having a magnitude equal to or greater than a predetermined value is continuously detected for 10 minutes or more”, or to use both in combination.

  When the operation mode is switched to the alarm theft mode M11 at time t6, a warning by the alarm (horn 41) is started. In this warning, the blinker lamp 42 is also blinked together with the alarm. In the present embodiment, the alarm is set to stop for 5 minutes after being activated for a time AL2 (for example, 3 minutes), so that a warning to a third party is effectively performed and the power consumption of the in-vehicle battery 63 is increased. It is possible to achieve both reductions. The operation patterns of the horn 41 and the blinker lamp 42 can be arbitrarily changed.

  At time t6 when switching to the alarm theft mode M11, the vibration detection permission state is switched from permission to prohibition, and the vehicle-mounted telephone 11 (see FIG. 1) is driven by the communication control unit 12, so that the vehicle body is in an abnormal state. Is notified to the user's telephone 3 or personal computer. In this communication, vehicle current position information detected by GPS is also transmitted. In this embodiment, this communication is performed once every five minutes, and the latest information can be updated as appropriate while reducing power consumption. Thereby, the user of the vehicle can know the moving route of the vehicle after the vehicle reaches an abnormal state. It is also possible to take measures such as sending information related to the abnormal state of the vehicle to the provider 4 and requesting cooperation from the police or a security company via the provider 4.

  Note that GPS and GSM are switched to the operating state at time t5 when the third vibration input is performed. This is because, at time t5, GPS and GSM are activated in advance in a state where it is determined to be abnormal if there is another vibration input within 5 minutes. This is a setting for recording the position of the vehicle. It is also effective for quickly starting wireless communication when an abnormal state is determined. Note that the movement history information by GPS is also recorded in a memory in the GPS.

  In addition, as described above, providing a plurality of vibration input patterns ensures that various abnormal states are determined as abnormal states, and how abnormalities are generated by the vibration patterns that have been determined as abnormal states. This is because there is a possibility that the user or the like can guess whether or not it has been done.

  For example, in the case where “the vibration of the magnitude greater than or equal to the predetermined value is detected three times within the first 5 minutes after the vibration of the magnitude greater than or equal to the predetermined value is first detected” There is a possibility that it can be detected that the exterior parts and the battery are removed. In addition, “it was repeated twice that the vibration of the predetermined value or more was detected once within 5 minutes or more and 10 minutes after the vibration of the predetermined value or more was first detected” In some cases, it may be possible to detect that a destructive operation such as a chain lock that connects the vehicle and the pillar or the like, or a bar lock that makes the wheels unrotatable is being performed. In addition, if “a vibration with a magnitude greater than a predetermined value is detected continuously for 10 minutes or more”, it is detected that the vehicle is immediately loaded on a truck for transportation and the truck is running. There is a possibility.

  In addition, if the vibration pattern that has been determined to be an abnormal state is notified during the wireless communication described above, there is a possibility that the user or the provider can guess what abnormal state the vehicle is in. Become.

  Incidentally, in the example of FIG. 8, the ignition SW 25 is switched on at time t7. This corresponds to, for example, a situation in which the ignition SW 25 is turned on to stop the warning means 40 when the user has mistakenly shifted to the alarm theft mode M11 when the vehicle is being maintained. To do. However, the abnormality detection device 10 according to the present embodiment is configured such that the alarm theft mode M11 is not canceled only by turning on the ignition SW 25.

  The transition from the alarm theft mode M11 to the normal mode M8 with provider contract (see FIG. 7) is performed only when the user calls the in-vehicle telephone and transmits the theft mode release signal. In the example of FIG. 8, the theft mode release signal is received at time t8, the alarm theft mode M11 shifts to the provider contracted normal mode M8, and the warning by the horn 41 and the blinker lamp 42 is also stopped. If the ignition SW 35 is off when the theft mode release signal is received, the process shifts to the sleep mode M10.

  As described above, according to the abnormality detection device of the present invention, for example, “After a vibration having a magnitude equal to or greater than a predetermined value is first detected, a vibration having a magnitude greater than or equal to a predetermined value is detected within 5 minutes. Since it is determined that the state is abnormal only when a predetermined pattern consisting of a combination of the vibration detection interval and the number of times of detection is detected, such as when “detected once is repeated three times”. For example, when a passerby accidentally touches the vehicle body, it can be prevented that the abnormal state is determined only by detecting a temporary vibration.

  It should be noted that the configuration and arrangement of the abnormality detection device, the types of various sensors and warning means that detect abnormal conditions, the configuration of the display means, the function of the communication control unit, the type of communication standard of the in-vehicle telephone, the GPS usage method, Lighting pattern, predetermined vibration input pattern for determining an abnormal state, operation pattern of alarm (warning means), communication content and communication frequency when determined to be an abnormal state are not limited to the above embodiment, Various changes are possible. The abnormality detection device according to the present invention is not limited to a motorcycle, and can be applied to a tricycle, a four-wheel vehicle, or the like.
