Description

  The present invention relates to a vehicle theft prevention device and a vehicle theft prevention system that can detect the occurrence of a vehicle abnormality such as the entry of a suspicious person into a vehicle such as an electric vehicle or a hybrid vehicle.

  In recent years, an electric vehicle (EV (Electric Vehicle) vehicle) or a hybrid vehicle that travels by being connected to an external power supply device via a charging cable to charge the battery and driving a motor with electric power stored in the battery Vehicles (so-called plug-in vehicles) such as (HEV (Hybrid Electric Vehicle)) are beginning to spread. In such a plug-in vehicle, it takes several tens of minutes to several hours to fully charge the battery, and the power feeding device and the vehicle are connected via the charging cable for a long time. There is a risk of being left unattended.

  Various devices such as a car navigation device and an audio device are mounted in the vehicle interior of the vehicle, and driving assistance of the vehicle by the user or improvement of living comfort in the vehicle is performed. However, since these in-vehicle devices are expensive, theft crimes for in-vehicle devices such as so-called vandalism frequently occur. In the plug-in vehicle as described above, since it takes a long time to charge the battery, there is a high possibility that the user will leave the vehicle, and the possibility of theft being increased in such a case.

  Patent Document 1 proposes a power supply device for a vehicle that can prevent mischief or theft during charging. This power supply device includes a main battery that supplies electric power to the motor and a connecting part that connects a charging cable for charging from outside the vehicle, and a connector provided at an end of the charging cable is connected to the connecting part. The lock mechanism is configured to be unlockable by a vehicle key.

  On the other hand, some devices for preventing theft of a vehicle have a function of, for example, detecting a suspicious person's entry into the vehicle and issuing an alarm or a report. A vehicle antitheft device having such an intrusion detection function outputs, for example, a microwave or an ultrasonic wave from an instrument panel or a ceiling portion in the vehicle, and detects a reflected wave to examine a change in frequency. It can be configured to detect the presence or absence of an intruder in the vehicle. The vehicle antitheft device having this configuration utilizes the fact that the frequency of the reflected wave detected with respect to the output microwave or ultrasonic wave changes when an object that reflects the microwave or ultrasonic wave is moving. Thus, an object (intruder) that moves in the vehicle is detected.

The body ECU 20 classifies the contents of control by the security function into four states (a no-warning state C0, a warning preparation state C1, a warning state C2, and an abnormality occurrence state C3).

  The unguarded state C0 is a state in which it is not necessary to operate the security function, for example, when the EV vehicle 1 is traveling or when the user is in the EV vehicle 1, and the body ECU 20 transitions to the alert preparation state C1. It waits until the condition J1 is satisfied. As the transition condition J1, for example, a case where the READY monitor 11 instructs the READY off state and all the doors of the EV vehicle 1 are locked can be considered. Further, the transition condition J1 may be set such that the user operates a switch or the like that activates the security function (for example, a theft alarm function release switch provided in advance is turned off).

  In the warning preparation state C1, if the operation of the security function is started immediately after the transition condition J1 is established, there is a possibility that a true user or the like of the EV vehicle 1 may be erroneously detected as a suspicious person. A standby state is provided. The body ECU 20 operates an internal timer or the like when transitioning to the alert preparation state C1, and transitions to the alert state C2 when a predetermined time (for example, several tens of seconds to several minutes) has elapsed (transition condition J2 is satisfied). To do.

  In the warning state C2, the body ECU 20 uses the hall element 9 mounted on the EV vehicle 1 and other sensors (for example, a sensor that detects approach to the EV vehicle 1, a sensor that detects vibration of the EV vehicle 1, etc.). This is a state in which a detection process is performed to determine whether an abnormality has occurred in the vehicle 1. When the body ECU 20 detects a vehicle abnormality related to the EV vehicle 1 such as detection of intrusion into the EV vehicle 1 (the transition condition J3 is established), the body ECU 20 transitions to the abnormality occurrence state C3. The body ECU 20 may set a condition other than detection of an abnormal state of the EV vehicle 1 by the hall element 9 and detection of abnormality based on detection results of other sensors as the transition condition J3. For example, when the door of the EV vehicle 1 is opened by unauthorized means, or when the battery of the EV vehicle 1 is reconnected after being disconnected, the transition condition J3 is set to change from the warning state C2. You may make it change to abnormality occurrence state C3.

  The abnormality occurrence state C3 indicates that an abnormality occurrence of the EV vehicle 1 is detected and abnormality content transmission processing P31 mainly including transmission of in-vehicle camera captured image data D30 and the like to the power feeding device 50 and users around the EV vehicle 1 or This is a state in which any one of the abnormal alarm processing P32 mainly for warning to a third party is performed.

  The abnormality content transmission process P31 is a process executed when the EV vehicle 1 is in a chargeable state, and the abnormality alarm process P32 is a process executed when the EV vehicle 1 is in an unchargeable state.

(Abnormal content transmission process P31)
First, the abnormality content transmission process P31 will be described. The body ECU 20 mainly transmits the in-vehicle camera captured image data D30 and the abnormality instruction information D40 instructing the occurrence of an abnormal state to the power supply device 50 by power line communication via the charging cable 70 using the power line communication unit 7. The abnormal content transmission process P31 is executed.

  The body ECU 20 according to the first embodiment may also perform a vehicle-related prohibiting operation described below as a series of operations in the abnormality content transmission process P31.

  The body ECU 20 locks the plug portion 71 of the charging cable 70 so as not to be removable from the charging port 1a by operating the plug lock mechanism 6, and locks all doors of the EV vehicle 1 by operating the door lock mechanism 12. Then, the closed window of the EV vehicle 1 is locked by operating the window opening / closing mechanism 13, and the motor start of the EV vehicle 1 is prohibited by giving a motor start prohibition command to the motor control device 10. Thus, the body ECU 20 may perform a series of vehicle-related prohibiting operations as the abnormality content transmission process P31.

  The body ECU 20 performs the vehicle-related prohibition operation, that is, after the charging cable 70 is locked, the door is locked, the window is closed, and the engine start is prohibited once. Even when an operation on the operation unit in the EV vehicle 1 is performed until the transition to, the vehicle-related prohibited operation is released, that is, the charging cable 70 is locked, the door is unlocked, and the window is unlocked. And engine start permission is not performed.

  In addition, when the transition condition J5 for stopping the security function is satisfied in the alert preparation state C1, the alert state C2, and the abnormality occurrence state C3, the body ECU 20 stops the processing in each state and goes to the no alert state C0. Transition. For example, when the door of the EV vehicle 1 is unlocked by legitimate means, the transition condition J5 is when the user operates a switch or the like that stops the security function (e.g., a theft occurrence alarm function release switch provided in advance). This is established when the READY monitor 11 is instructed to be turned on. When the charging cable 70 is locked, the door is locked, the window is locked, and the engine start is prohibited by the vehicle-related prohibiting operation, the vehicle-related after the transition condition J5 is satisfied and the body ECU 20 transitions to the unwarranted state C0. The prohibition operation is released, and the charging cable 70 can be removed, the door unlocked, the window unlocked, and the engine can be started.

  Next, the abnormality alarm process P32 will be described. The body ECU 20 drives the illumination drive mechanism 14 and the alarm mechanism 15 to use the warning light from the illumination of the headlight 5 and the like and the warning sound from the horn provided in the EV vehicle 1 to activate the vehicle antitheft device. An abnormal alarm process P32 mainly for notifying an intruder of the EV vehicle 1 and notifying a user or a third party existing around the EV vehicle 1 of the occurrence of an abnormal state of the EV vehicle 1 is performed. Run.

  In addition, the body ECU 20 according to the first embodiment may perform the above-described vehicle-related prohibiting operation as a series of operations in the abnormality alarm process P32. However, at the time of abnormal alarm processing P32, in order to notify the intruder that the vehicle anti-theft device has been operated, the operation of closing the window that closes the opened window is changed to the window lock operation in order to capture the intruder with certainty. It is better to do it first.

  As described above, the body ECU 20 performs the control process for realizing the security function by changing the four states C0 to C3. When the READY monitor 11 is in the READY state, the body ECU 20 is in an unwarranted state C0, and in this state, the angle adjustment process of the headlight 5 according to the vehicle height is performed. When the READY monitor 11 is switched from on to off, the body ECU 20 stops the angle adjustment process of the headlight 5 and starts the vehicle abnormality detection process including the intrusion detection process into the EV vehicle 1. In the no-warning state C0, only the preparation processing (for example, register initialization) for the intrusion detection processing is performed, and the actual vehicle abnormality detection processing is performed after shifting to the warning state C2.

  In the vehicle abnormality detection process related to the EV vehicle 1 using the Hall element 9, the body ECU 20 acquires the output voltage value of the Hall element 9 when performing the state transition from the warning preparation state C1 to the warning state C2. The acquired voltage value is stored as a reference voltage value. Thereafter, the body ECU 20 periodically drives the hall element 9 to obtain an output voltage value, and calculates a difference between the obtained output voltage value and the stored reference voltage value, thereby outputting the output voltage value of the hall element 9. The amount of change is calculated. Furthermore, the body ECU 20 determines whether or not the calculated change amount exceeds a predetermined threshold value. If the calculated change amount exceeds the threshold value, it can be determined that the vehicle height of the EV vehicle 1 has changed. It is determined that a vehicle abnormality such as a suspicious person has entered 1 has occurred.

  FIG. 6 is a schematic diagram for explaining a method for detecting a vehicle abnormality such as an intrusion into the EV vehicle 1, and is a commercial vehicle equipped with a headlight adjustment function corresponding to the vehicle height. The graph shows the result of measuring the output voltage value of the vehicle height sensor against intrusion. In the figure, the vehicle height sensor when 0 to 2 passengers get on the driver's seat, front passenger seat, rear right seat (rear right seat) or rear left seat (rear left seat). The output voltage value is shown. Further, in the figure, the measurement result L1 of the output voltage value indicated by the solid line is a result of measurement performed by stopping the vehicle on a flat ground, and the measurement result L2 of the output voltage value indicated by the broken line is the rear part of the vehicle. As a result, the measurement was performed by stopping the vehicle at a slope of about 5.3 degrees so that the value of the output voltage was high. The measurement result L3 of the output voltage value indicated by the one-dot chain line was about 5. It is the result of having stopped and measured on the slope of 3 degrees.

  From the measurement results shown in FIG. 6, the greater the number of passengers in the vehicle, the greater the amount of change in the output voltage value of the vehicle height sensor with respect to the reference voltage value when there is no passenger. Even when one occupant with the smallest amount of change gets into the driver's seat, the output voltage value of the vehicle height sensor changes by about 0.1 V with respect to the reference voltage value. A change of about 0.1 V can be detected, and by detecting this change in voltage value, the intrusion of a suspicious person into the vehicle can be detected. For example, the body ECU 20 predetermines 0.07 V as a change amount threshold value, and determines that a vehicle abnormality has occurred (intrusion has occurred) when the output voltage value of the vehicle height sensor with respect to the reference voltage value exceeds this threshold value. That's fine.

  However, there is a possibility that the vehicle height may change due to a temporary shake or the like applied to the EV vehicle 1 due to an external factor. When such a vehicle height change exceeds a threshold, the EV vehicle 1 There is a risk of misidentification of intrusion. Therefore, after determining that the calculated amount of change in the voltage value exceeds the threshold, the body ECU 20 in the first embodiment further determines whether or not this change has been maintained for a predetermined period (for example, several tens of seconds to several tens of seconds). It is determined, and it is determined that the vehicle is abnormal when a change exceeding the threshold is maintained for a predetermined period.

  FIG. 7 is a block diagram illustrating an internal configuration of the power supply apparatus 50. The power supply device 50 includes a power supply control unit 51, a connection unit 53, a power line communication unit 54, a LAN (Local Area Network) communication unit 55, a drive circuit 56, an alarm device 57, and the like. The power supply control unit 51 is interposed between the power source 52 and the connection unit 53 to which the charging cable 70 is connected, and supplies power by connecting / cutting off the power supply path from the power source 52 to the connection unit 53. The start / stop control is performed. The power source 52 supplies AC power having a voltage value of 100 V or 200 V and a frequency of 50 Hz or 60 Hz, and may be a commercial AC power source or the like. The power source 52 may not be provided in the power feeding device 50. The connection part 53 may be configured such that the charging cable 70 can be removed, or may be configured so as not to be removable.

  The power line communication unit 54 performs transmission by modulating and superimposing the transmission data provided from the power supply control unit 51 on the power supply path from the power supply control unit 51 to the connection unit 53, and the superimposed signal Received data obtained by separating and demodulating is supplied to the power feeding control unit 51. By performing power line communication by the power line communication unit 54 with the EV vehicle 1 connected via the charging cable 70, the power supply control unit 51 can perform authentication processing or charging information transmission / reception processing. In addition, when the abnormality instruction information D40 is received from the EV vehicle 1 connected via the charging cable 70, the power supply control unit 51 performs an alarm sound generation process by the alarm device 57 as necessary.

  Furthermore, the power supply device 50 includes a power supply monitoring camera 35 that can image the state of the vehicle to be charged in the operation state, and is in an operation state under the control of the power supply control unit 51. The state of the vehicle, that is, the content of the abnormality can be acquired as power supply side camera captured image data D35 (power supply side imaging information).

  The LAN communication unit 55 communicates with the centralized management center 80 via the network NW, whereby the power supply control unit 51 can acquire information for authentication processing from another device, for example. it can. In addition, when the in-vehicle camera photographed image data D30 and the abnormality instruction information D40 are given from the EV vehicle 1 connected via the charging cable 70, the power supply control unit 51 uses the LAN communication unit 55 to supply the power supply side monitoring camera 35. The in-vehicle camera photographed image data D30 and the abnormality instruction information D40 are transmitted to the centralized management center 80 together with the power supply side camera photographed image data D35 acquired from the above.

  The alarm device 57 is for generating an alarm sound according to the abnormality instruction information D40 from the EV vehicle 1, and may be, for example, a sound output device such as a buzzer or a speaker for generating an alarm sound. Moreover, the alarm device 57 is not limited to a sound output but may be a device that lights a lamp or the like, for example. The drive circuit 56 operates under the control of the power supply control unit 51 and outputs a drive signal to the alarm device 57 to cause the alarm device 57 to output an alarm sound. When the power feeding control unit 51 receives the abnormality instruction information D40 from the EV vehicle 1, the power feeding control unit 51 operates the drive circuit 56 to output an alarm sound by the alarm device 57 as necessary. Moreover, the electric power feeding control part 51 stops the output of the alarm sound by the alarm device 57, when the notification of cancellation | release of abnormality instruction information D40 is given from the EV vehicle 1. FIG.

  Next, a process performed by the body ECU 20 of the EV vehicle 1 and a process performed by the power supply control unit 51 of the power supply apparatus 50 will be described using a flowchart.

  FIG. 8 is a flowchart showing a procedure of processing performed by the body ECU 20 in the unguarded state C0. In the unguarded state C0, first, the body ECU 20 determines whether or not the READY monitor 11 instructs the READY on state (step S1). When the READY monitor 11 instructs the READY ON state (S1: YES), the body ECU 20 drives the hall element 9 in a short cycle (step S2), and synchronizes with the timing when the hall element 9 is driven. 9 is obtained (step S3). Next, the body ECU 20 determines whether or not the acquired output voltage value of the hall element 9 is within a normal range as a failure detection of the hall element 9 (step S4). If the output voltage value of the Hall element 9 is within the normal range (S4: YES), the body ECU 20 gives an instruction to the angle adjustment mechanism 4 according to the acquired output voltage value, thereby determining the irradiation angle of the headlight 5. An adjustment process is performed (step S5), and the process returns to step S1. If the output voltage value of the hall element 9 is outside the normal range (S4: NO), the body ECU 20 returns the process to step S1 without performing the adjustment process of the irradiation angle of the headlight 5.

  When the READY monitor 11 instructs the READY off state (S1: NO), the body ECU 20 drives the hall element 9 in a long cycle (step S6), for example, all the doors of the EV vehicle 1 are locked or For example, it is determined whether or not a transition condition J1 such as a user operating a switch for operating a security function is satisfied (step S7). If the transition condition J1 is not satisfied (S7: NO), step The process returns to S1. When the transition condition J1 is satisfied (S7: YES), the body ECU 20 sets the state related to the security function as the warning preparation state C1 (step S8), and ends the processing of the no warning state C0.

  FIG. 9 is a flowchart showing a procedure of processing performed by the body ECU 20 in the alert preparation state C1. In the warning preparation state C1, the body ECU 20 indicates that, for example, the door of the EV vehicle 1 is unlocked by legitimate means, the user operates a switch for stopping the security function, or the READY monitor 11 is in the READY ON state. It is determined whether or not a transition condition J5 such as switching to is established (step S21). When the transition condition J5 is satisfied (S21: YES), the body ECU 20 sets the state in the security function to the no alert state C0 (step S27), and ends the process of the alert preparation state C1.

  When the transition condition J5 is not satisfied (S21: NO), the body ECU 20 determines whether or not a predetermined time has elapsed since the transition to the alert preparation state C1, that is, whether or not the transition condition J2 is satisfied (step S22). ). When transition condition J2 is not satisfied (S22: NO), body ECU 20 returns the process to step S21.

  When the transition condition J2 is satisfied (S22: YES), the body ECU 20 acquires the output voltage value of the Hall element 9 (Step S23), and the acquired output voltage value of the Hall element 9 is detected as a failure detection of the Hall element 9. It is determined whether it is within the normal range (step S24). If the output voltage value of the hall element 9 is within the normal range (S24: YES), the body ECU 20 stores the acquired output voltage value as a reference voltage value (step S25), and the state related to the security function is a warning state C2. (Step S26), the process of the alert preparation state C1 is terminated. If the output voltage value of the Hall element 9 is outside the normal range (S24: NO), the body ECU 20 sets the state related to the security function as the warning state C2 without storing the reference voltage value (step S26). The process of the preparation state C1 ends.

  FIG. 10 is a flowchart illustrating a procedure of processing performed by the body ECU 20 in the alert state C2. In the alert state C2, the body ECU 20 determines whether or not the transition condition J5 is satisfied (step S41), and when the transition condition J5 is satisfied (S41: YES), the vehicle is already in the abnormality occurrence state C3. If the related prohibition operation is executed, the door unlocking of the EV vehicle 1, the unlocking of the window and the prohibition of the engine start are canceled (step S48), and the state in the security function is set to the unguarded state C0 (step S49). The process of the alert state C2 is finished.

  When the transition condition J5 is not satisfied (S41: NO), the body ECU 20 acquires the output voltage value of the Hall element 9 in synchronization with the timing of driving the Hall element 9 (Step S42), and detects the failure of the Hall element 9 Then, it is determined whether or not the acquired output voltage value of the Hall element 9 is within the normal range (step S43). If the output voltage value of the hall element is outside the normal range (S43: NO), the body ECU 20 returns the process to step S41. If the output voltage value of the Hall element 9 is within the normal range (S43: YES), the body ECU 20 calculates the difference between the acquired output voltage value of the Hall element 9 and the stored reference voltage value. Thus, the change amount of the output voltage value is calculated (step S44). If the failure of the Hall element 9 is detected in the process of the warning preparation state C1 and the reference voltage value is not stored, the body ECU 20 does not calculate the amount of change in step S44 and proceeds to step S41. Return it.

  Next, the body ECU 20 determines whether or not the calculated change amount exceeds a predetermined threshold value (step S45). When the change amount exceeds the threshold value (S45: YES), the change exceeding the threshold value is predetermined. It is further determined whether or not it is maintained over time (transition condition J3) (step S46). When the change amount does not exceed the threshold value (S45: NO), or when the change exceeding the threshold value is not maintained for a predetermined time (S46: NO), the body ECU 20 returns the process to step S41. When the change exceeding the threshold is maintained for a predetermined time (S46: YES), the body ECU 20 determines that a vehicle abnormality has been detected, and sets the state in the security function as the abnormality occurrence state C3 (step S47), and is in a warning state. The process of C2 is terminated.

  FIG. 11 is a flowchart showing a procedure of processes performed by the body ECU 20 in the abnormal state occurrence state C3.

  In the abnormality occurrence state C3, first, the body ECU 20 determines whether or not it is in a communicable state (chargeable state) (step S50). That is, it is determined whether or not the charging cable 70 used for power line communication is connected to the charging port 1a. Whether or not the charging cable 70 is connected to the charging port 1a may be detected, for example, by providing a switch or the like at the charging port 1a, and power line communication with the power supply device 50 is possible. The configuration may be determined based on whether or not, or may be determined by other methods.

  As described above, since the vehicle antitheft device according to the first embodiment employs the contact-type charging method and power line communication (wired communication) using the common charging cable 70, the body ECU 20 uses the charging cable 70. The presence / absence of the communicable state can be recognized based on the presence / absence of the communicable state, and the presence / absence of the communicable state of power line communication performed using the same charging cable can be recognized.

  When the communication is possible (S50: YES), the power line communication to the power supply device 50 is possible. Therefore, the abnormal content transmission process P31 mainly including the transmission of the in-vehicle camera captured image data D30 to the power supply device 50. (Step S51) is executed. On the other hand, when the communication is disabled (S50: NO), the power line communication to the power supply device 50 is impossible, so that the abnormality alarm processing P32 (step 32) mainly including an abnormality alarm to the neighbors of the EV vehicle 1 is performed. S51) is executed.

  FIG. 12 is a flowchart showing the procedure of the abnormal content transmission process P31 executed by the body ECU 20.

  As abnormality content transmission processing P31, first, the body ECU 20 gives an instruction to the plug lock mechanism 6 to lock the plug portion 71 of the charging cable 70 connected to the charging port 1a so as not to be removable (step S60). And by giving an instruction to the door lock mechanism 12, all the doors of the EV vehicle 1 are locked, and unlocking of all the doors is prohibited (step S61), and by giving an instruction to the window opening and closing mechanism 13, The opening operation of all closed windows in the EV vehicle 1 is prohibited (step S62), and an instruction is given to the motor control device 10 to prohibit the start of the motor of the EV vehicle 1 (step S63).

  Then, the monitoring camera group 30 is set in the operating state, and the in-vehicle camera photographed image data D30 is acquired from the monitoring camera group 30 (step S65).

  Thereafter, the body ECU 20 uses the power line communication unit 7 to instruct the occurrence of an abnormality in the EV vehicle 1 together with the in-vehicle camera photographed image data D30 via the charging cable 70 connected to the charging port 1a of the EV vehicle 1. The abnormality instruction information D40 is transmitted to the power supply device 50 (step S66).

  As described above, in the abnormality content transmission process P31, after the vehicle-related prohibiting operation in steps S60 to S63 is executed, the data transmission process in steps S65 and S66 is executed. The reason why the window closing operation is not executed in step S62 is that the intruder into the EV vehicle 1 is not aware that the abnormal content transmission process P31 is being executed.

  Next, the body ECU 20 determines whether or not the transition condition J5 is satisfied (step S67). When the transition condition J5 is satisfied (S67: YES), the body camera 20 is set in a non-operating state, and an abnormality is detected. Information for instructing the cancellation of the instruction information D40 is given to the power supply apparatus 50 by power line communication via the charging cable 70 (step S71).

  Next, the body ECU 20 cancels the prohibition of door unlocking, window locking, and motor start of the EV vehicle 1, that is, cancels the vehicle-related prohibiting operation (step S72), and sets the state in the security function as the unwarranted state C0. (Step S73), the process of the abnormal state occurrence state C3 is terminated.

  On the other hand, when transition condition J5 is not satisfied (S67: NO), body ECU 20 returns to step S66 and continues the data transmission process to power supply device 50. Thereafter, the processes of steps S66 and S67 are repeated until the transition condition J5 is satisfied (S67: YES). Since it is sufficient to transmit the abnormality instruction information D40 once, only the in-vehicle camera photographed image data D30 may be transmitted at the second and subsequent executions of step S66.

(Abnormal alarm processing P32)
FIG. 13 is a flowchart showing a procedure of an abnormal alarm process P32 executed by the body ECU 20.

  As the abnormality alarm process P32, first, the body ECU 20 gives an instruction to the door lock mechanism 12 to lock all the doors of the EV vehicle 1 and prohibit the unlocking of all the doors (step S61). . Then, by giving an instruction to the window opening / closing mechanism 13, all windows of the EV vehicle 1 are closed, and the opening operation of the closed window is prohibited (locked) (step S62), and an instruction is given to the motor control device 10. By giving, the start of the motor of the EV vehicle 1 is prohibited (step S63).

  After that, by using the illumination drive mechanism 14 and the alarm mechanism 15 to execute alarm processing using at least one of the illumination including the headlight 5 and the light and sound driving the horn, users around the EV vehicle 1 Alternatively, a third party is notified that an abnormality has occurred in the EV vehicle 1 in a perceptible manner (step S64).

  As described above, in the abnormal alarm process P32, the alarm process is executed after the vehicle-related prohibition operation in steps S60 to S63 is executed, as in the abnormal content transmission process P31. In step S62 in the alarm processing P32 at the time of abnormality, an operation for closing the open window is performed in advance. The reason for performing the operation of closing the window in the open state is to prioritize the capture of the intruder into the EV vehicle 1 and the notification to the neighbors of the EV vehicle 1.

  Next, the body ECU 20 determines whether or not the transition condition J5 is satisfied (step S67). When the transition condition J5 is satisfied (S67: YES), the alarm processing of step S64 is stopped (step S71). .

  Next, the body ECU 20 cancels the vehicle-related prohibiting operations such as door unlocking, window locking, and motor starting prohibition of the EV vehicle 1 (step S72), and sets the state in the security function to the unwarranted state C0 (step S73). The processing of the abnormal state occurrence state C3 is terminated.

  On the other hand, when the transition condition J5 is not satisfied (S67: NO), step S67 is repeated, and thereafter, the process of step S67 is repeated until the transition condition J5 is satisfied (S67: YES).

  FIG. 14 is a flowchart illustrating a procedure of processing performed by the power feeding device 50 in conjunction with the abnormality content transmission processing P31 of the vehicle antitheft device of the first embodiment. Note that, when the abnormal time alarm process P32 is executed, it is impossible to perform communication, that is, it is impossible to perform power line communication to the power supply apparatus 50 via the charging cable 70. Therefore, the process of the power supply apparatus 50 illustrated in FIG. Never executed.

  The power feeding control unit 51 of the power feeding device 50 determines whether or not the abnormality instruction information D40 from the EV vehicle 1 via the charging cable 70 has been received (step S81), and if not received (S81: NO) ), And waits until receiving the abnormality instruction information D40.

  When the abnormality instruction information D40 is received from the EV vehicle 1 (S81: YES), the power supply control unit 51 puts the power supply monitoring camera 35 into an operating state, and the EV vehicle to be charged from the power supply monitoring camera 35. 1 is taken as an imaging target, and power supply side camera photographed image data D35 indicating the situation of the EV vehicle 1 is acquired from the power supply side monitoring camera 35 (step S82).

  Thereafter, the power supply control unit 51 uses the LAN communication unit 55 to transmit the in-vehicle camera captured image data D30 and the abnormality instruction information D40 together with the power supply side camera captured image data D35 to the centralized management center 80 via the network NW. Data is transmitted (step S83).

  As the central management center 80, for example, a dealer of the EV vehicle 1, a security company, or the like can be considered. In addition, when executing step S83, the power supply apparatus 50 may transmit a notification mail to, for example, a mobile phone possessed by the user of the EV vehicle 1 to an external mail server. Further, the central management center 80 may transmit the notification mail.

  Next, the power feeding device 50 drives the alarm device 57 by the drive circuit 56 (step S84), and outputs a warning sound or the like. Thereafter, the power supply device 50 determines whether or not the EV vehicle 1 has received a notification of cancellation of the abnormality instruction information D40 via the charging cable 70 (step S85), and is notified of the cancellation of the abnormality instruction information D40. If not (S85: NO), the process returns to step S84 to continue the alarm, and if the notification is canceled (S85: YES), the alarm is stopped and the process is terminated.

  FIG. 15 is an explanatory diagram showing a communication frame structure of data used when data of in-vehicle camera photographed image data D30 and abnormality instruction information D40 is transmitted via the charging cable 70.

  As shown in the figure, the communication frame 90 includes a synchronization bit group 91, a command bit group 92, an abnormality determination bit 93, a data bit group 94, and the like. The in-vehicle camera photographed image data D30 is stored in the data bit group 94, and the abnormality instruction information D40 is stored as the abnormality determination bit 93.

  For example, when the abnormality determination bit 93 that is the abnormality instruction information D40 is “1”, the occurrence of vehicle abnormality can be instructed, and when it is “0”, the occurrence (cancellation) of vehicle abnormality can be instructed. In the case of the above example, when the abnormality determination bit 93 is “1”, it is determined that the abnormality instruction information D40 has been received (S81: YES), and the abnormality determination bit 93 changes from “1” to “0”. However, it is determined that the cancellation notification of the abnormality instruction information D40 has been made (S85: YES).

  FIG. 16 is a perspective view schematically showing an example of data transmission from the body ECU 20 to the central management center 80 when the abnormal content transmission process P31 is executed.

  As shown in the figure, when the vehicle abnormality related to the EV vehicle 1 is detected by the determination process P1 based on the vehicle height sensor data D9, the body ECU 20 transmits the abnormality instruction information D40 to the power line communication unit 7 by the internal transmission process T1. Then, a reply process R1 for transmitting a reception confirmation from the power line communication unit 7 to the body ECU 20 is received.

  Further, the power line communication unit 7 transmits the abnormality instruction information D40 to the power supply device 50 through a transmission process T2 that is power line communication using the charging cable 70. Then, a reply process R2 for reception confirmation is received from the power supply apparatus 50.

  As described above, a process of transmitting only the abnormality instruction information D40 to the power supply apparatus 50 at an early stage by the transmission process T1 and the transmission process T2 is considered as an example. In this case, there is an advantage that the power supply monitoring camera 35 can be quickly brought into an operating state on the power supply device 50 side.

  As another example of data transmission, when the vehicle abnormality related to the EV vehicle 1 is detected by the determination process P1 based on the vehicle height sensor data D9, the body ECU 20 transmits the in-vehicle camera captured image data D30 to the power line communication unit 7 by the internal transmission process T3. And a reply process R3 for transmitting a reception confirmation from the power line communication unit 7 to the body ECU 20 is received.

  Furthermore, the power line communication unit 7 transmits the in-vehicle camera photographed image data D30 to the power supply device 50 by transmission processing T4 that is power line communication using the charging cable 70. Then, a reply process R4 for reception confirmation is received from the power supply apparatus 50.

  Then, the power feeding device 50 transmits the in-vehicle camera photographed image data D30 to the central management center 80 by transmission processing T5 that is communication using the network NW. Then, a reply process R5 for reception confirmation is received from the central management center 80.

  In this way, a process of transmitting the in-vehicle camera photographed image data D30 to the central management center 80 through the transmission processes T3 to T5 can be considered.

  In addition, the power supply apparatus 50 transmits the power-supply-side camera captured image data D35 acquired from the power-supply-side monitoring camera 35 to the centralized management center 80 by transmission processing T6 using the network NW. Then, a reply process R6 for reception confirmation is received from the central management center 80.

  In the first embodiment, the processes of the transmission processes T1 and T2 and the processes of the transmission processes T3 and T4 are combined and executed as batch transmission of the in-vehicle camera captured image data D30 and the abnormality instruction information D40 (step S66 in FIG. 12). ), The transmission process T5 and the transmission process T6 are collectively performed as a batch transmission process (step S83 in FIG. 14) of the in-vehicle camera captured image data D30 and the power supply side camera captured image data D35. Since the reply processes R1 to R6 are for reception confirmation and have low importance, the description thereof is omitted in the flowcharts of FIGS.

  The body ECU 20 configured as described above is configured to detect a vehicle abnormality such as intrusion into the EV vehicle 1 by using the hall element 9 for detecting the vehicle height of the EV vehicle 1, so that the vehicle related to the EV vehicle 1. The function of detecting an abnormality and the function of adjusting the irradiation angle of the headlight 5 according to the vehicle height are integrated in the body ECU 20, and the hall element 9 can be shared by both functions. The cost of the EV vehicle 1 can be reduced. Further, the body ECU 20 is configured to detect an abnormal state of the EV vehicle 1 according to the vehicle height, so that the intrusion detection range can be the entire area within the EV vehicle 1, and high-accuracy intrusion detection is realized. it can.

(Effects etc.)
The vehicle antitheft device according to the first embodiment is capable of acquiring in-vehicle camera captured image data D30 (vehicle-side imaging information) including at least the front camera image capturing data D31 indicating the situation in the EV vehicle 1 in the operating state. Group 30 is included. For this reason, during the charging period of the battery 2 via the charging cable 70, the abnormality content, which is the situation in the EV vehicle 1 when the vehicle abnormality is detected, is controlled under the control of the body ECU 20 as the abnormality control means. By transmitting the data D30 to the power supply device 50, the details of the facts in the abnormal state such as the entry into the EV vehicle 1 can be transmitted to the outside of the EV vehicle 1 quickly and accurately.

  In addition, the vehicle anti-theft device according to the first embodiment transmits abnormality indication information D40 to the power supply device 50, so that an abnormal occurrence of the EV vehicle 1 can be promptly performed to an authorized user or the like of the EV vehicle 1 on the power supply device 50 side. Can communicate.

  Note that the in-vehicle camera captured image data D30 is transmitted to the power feeding device 50 only when an abnormal state of the EV vehicle 1 occurs, so the transmission of the in-vehicle camera captured image data D30 itself is substituted for the abnormal state instruction by the abnormal instruction information D40. Thus, a mode in which the abnormality instruction information D40 is omitted is also conceivable.

  The vehicle antitheft device of the first embodiment does not execute alarm processing (processing corresponding to step S64 in FIG. 13) when the EV vehicle 1 and the power feeding device 50 are communicable by the charging cable 70. Without being noticed by the intruder of the EV vehicle 1, the vehicle abnormal state and its contents can be transmitted to the power supply device 50. As a result, it is possible to secure time for arresting an unsuspecting intruder into the EV vehicle 1 with the current offender, such as reporting to the police, and to improve the clearance rate of the intruder.

  In the case where it is important that the intruder does not notice that the vehicle abnormality has been detected by the vehicle antitheft device of the first embodiment, the processing of the vehicle-related prohibition operation shown in steps S60 to S63 shown in FIG. May be omitted, and only the data transmission process of the in-vehicle camera photographed image data D30 (abnormality instruction information D40) to the power supply apparatus 50 by executing steps S65 and S66 may be executed as the abnormal content transmission process P31. In this case, step S72 in FIG. 12 is also omitted. Further, it is desirable to omit the alarm process (step S83 in FIG. 14) by the power feeding device 50 as well.

  The vehicle antitheft device according to the first embodiment is configured to provide an alarm process (a process corresponding to step S64 in FIG. 13) when the charging cable 70 is not connected between the EV vehicle 1 and the power feeding device 50 and is in a communication disabled state (chargeable state). ) Is running. For this reason, when the abnormality of the EV vehicle 1 and the transmission of the abnormality content cannot be transmitted to the power supply device 50, an alarm process issued from the EV vehicle 1 to people around the EV vehicle 1 such as a user of the EV vehicle 1 Thus, the occurrence of an abnormal state of the EV vehicle 1 can be promptly notified.

  The vehicle antitheft system according to the first embodiment includes a monitoring camera group 30 and a power supply side monitoring camera 35 that can acquire the in-vehicle camera captured image data D30 and the power supply side camera captured image data D35 in the operating state. For this reason, during the charging period of the EV vehicle 1 and the battery 2 via the charging cable 70, the in-vehicle camera photographed image data D30 and the power supply side camera photographed image data D35 at the time of abnormality determination are controlled under the control of the body ECU 20. By transmitting to 80, the details of the fact of the abnormal state such as intrusion into the EV vehicle 1 can be quickly and accurately transmitted to the central management center 80 outside the vehicle.

  In the abnormal state C3, the body ECU 20 locks all the doors of the EV vehicle 1 to prohibit the unlocking, closes all the windows to prohibit the opening operation, and prohibits the EV vehicle 1 from starting the engine. By adopting a configuration in which the vehicle-related prohibiting operation can be executed, a suspicious person who has entered the EV vehicle 1 can be trapped and caught in the EV vehicle 1.

  Thus, since the vehicle antitheft device according to the first embodiment can capture the suspicious person (intruder) by executing the vehicle-related prohibiting operation, the suspicious person can more easily enter the EV vehicle 1. It can be effectively suppressed.

  Further, when an abnormality of the EV vehicle 1 is detected based on the detection result of the hall element 9 or the like, the plug lock mechanism 6 of the body ECU 20 is connected to the charging port 1a of the EV vehicle 1 and the plug portion 71 of the charging cable 70 is connected. By adopting a configuration in which the vehicle is locked so as not to be removable, it is possible to prevent the EV vehicle 1 itself from being stolen by an intruder.

  In addition, the output voltage value of the Hall element 9 is acquired as the reference voltage value at the start of the intrusion detection process (when the state transition from the warning preparation state C1 to the warning state C2), and thereafter (the warning state C2) The output voltage value is periodically acquired, the change amount of the output voltage value with respect to the reference voltage value is calculated, and when the calculated change amount exceeds the threshold value, it is determined that there is an intrusion into the EV vehicle 1. . With this configuration, since the intruder can be detected in the entire area of the EV vehicle 1 regardless of the position of the intruder in the EV vehicle 1, highly accurate vehicle abnormality detection can be realized.

  Further, when the change amount of the hall element 9 exceeds the threshold value and this change is maintained for a predetermined time, it is determined that there is an intrusion into the EV vehicle 1 so that the EV vehicle 1 is externally provided. It is possible to prevent erroneous determination that there is an intrusion into the EV vehicle 1 with respect to a change in the vehicle height caused by a temporary shake applied due to a factor or the like.

  Further, the state of the READY monitor 11 indicating whether or not the EV vehicle 1 can travel is acquired, and when the READY monitor 11 is in the READY ON state, the angle adjustment process of the headlight 5 is performed, and the READY monitor 11 is in the READY OFF state. If the hall element 9 is shared for both angle adjustment and intrusion detection processing, the vehicle height sensor should be used in a method suitable for each processing. Can do.

<Embodiment 2>
FIG. 17 is a block diagram showing a configuration of a vehicle antitheft system according to the second embodiment of the present invention. As shown in the figure, EV vehicle 1B is connected to power supply device 50 installed outside the vehicle via charging cable 70, as in EV vehicle 1 of Embodiment 1, and is used to drive a motor for running. Is charged in the battery 2 (see FIG. 18).

  As described above, in the second embodiment, as in the first embodiment, the contact type charging method is adopted using the charging cable 70 as the charging method (predetermined charging method). In the following description, components having the same reference numerals appropriately operate in the same manner as in the first embodiment, and thus description thereof will be omitted as appropriate, and differences from the first embodiment will be mainly described.

  FIG. 18 is a block diagram showing a configuration of a vehicle antitheft device mounted on the EV vehicle 1B.

  The EV vehicle 1 </ b> B includes a wireless communication unit 7 </ b> X that performs wireless communication with the power feeding device 50 using the antenna 8 instead of the power line communication unit 7.

  The radio communication unit 7X obtains from the antenna 8 by performing radio transmission using the antenna 8 by modulating and superimposing transmission data given from the body ECU 20, and separating and demodulating the superimposed signal. The received data is given to the body ECU 20. When the body ECU 20 detects a vehicle abnormality such as intrusion into the EV vehicle 1B by the security function, the body ECU 20 uses the wireless communication unit 7X to detect the situation in the EV vehicle 1B such as the in-vehicle camera captured image data D30. Information indicating the content of the abnormality can be transmitted to the power supply apparatus 50 by wireless transmission.

  As described above, the second embodiment employs wireless communication as a communication method (predetermined communication method), and the wireless communication unit 7X performs wireless communication using the antenna 8.

(Abnormal content transmission process P31)
In the second embodiment, the abnormality content transmission process P31 is performed in the same manner as in the first embodiment (see FIG. 12), but the main point is that the abnormal content transmission process P31 is transmitted to the power feeding device 50 by wireless communication using the wireless communication unit 7X. The communication method is different.

  FIG. 19 is a block diagram illustrating an internal configuration of the power feeding device 50B. The power feeding device 50 </ b> B is different in that a wireless communication unit 54 </ b> X and an antenna 58 are provided instead of the power line communication unit 54.

  The wireless communication unit 54X modulates and superimposes transmission data provided from the power supply control unit 51 (wireless communication unit 7X) of the EV vehicle 1B, thereby performing wireless transmission using the antenna 58 and via the antenna 58. Received data obtained by separating and demodulating the superimposed signal obtained in this way is supplied to the power feeding control unit 51. The power feeding device 50B performs wireless communication with the EV vehicle 1B using the wireless communication unit 54X, so that the power feeding control unit 51 can perform authentication processing, billing information transmission / reception processing, and the like. In addition, when the abnormality instruction information D40 is received from the EV vehicle 1B by wireless communication, the power supply control unit 51 performs an alarm sound generation process by the alarm device 57 as necessary.

  In addition, the power supply control unit 51 uses the LAN communication unit 55 to supply power when the in-vehicle camera captured image data D30 and the abnormality instruction information D40 are given via the wireless communication unit 54X by wireless communication from the EV vehicle 1B. The in-vehicle camera photographed image data D30 and the abnormality instruction information D40 are transmitted to the central management center 80 together with the power supply side camera photographed image data D35 acquired from the monitoring camera 35.

  In the second embodiment, the processing contents performed by the body ECU 20 in the abnormality occurrence state C3 are the same as those in the first embodiment (see FIG. 11).

  However, the content of step S50 in FIG. 11 is different from that in the first embodiment. In step S50, the body ECU 20 determines whether or not communication is possible with respect to wireless communication by the wireless communication unit 7X. For example, the determination is made based on whether or not wireless communication is possible with the power supply device 50B using the wireless communication unit 7X.

  And when it is a communicable state (S50: YES), since the wireless communication to the electric power feeder 50B is possible, the abnormal content transmission process P31 (step S51) is performed and it is a communication impossible state (S50 :). NO) performs wireless communication with the power supply device 50B, and therefore performs an abnormal alarm process P32 (step S51).

  The procedure of the abnormality content transmission process P31 executed by the body ECU 20 is performed in the same manner as in the first embodiment (see FIG. 12). However, the difference is that the data transmission to the power supply apparatus 50B in step S66 and the transmission of information instructing the cancellation of the abnormality instruction information D40 in step S71 are performed by wireless communication by the wireless communication unit 7X.

(Abnormal alarm processing P32)
In the second embodiment, the procedure of the abnormality warning process P32 executed by the body ECU 20 is performed in the same manner as in the first embodiment (see FIG. 13).

  In the second embodiment, the procedure of the process performed by the power feeding device 50B in conjunction with the abnormal content transmission process P31 of the vehicle antitheft device is performed in the same manner as in the first embodiment (see FIG. 14).

  However, the difference is that the presence / absence of reception of abnormality instruction information D40 from the vehicle 1B in step S81 and the presence / absence of notification of cancellation of the abnormality instruction information D40 from the vehicle 1B in step S85 are determined based on the presence / absence of reception by wireless communication.

  In the second embodiment, a communication frame structure in wireless communication of data used at the time of data transmission of the in-vehicle camera captured image data D30 and the abnormality instruction information D40 is adopted by the communication frame 90 shown in FIG.

  In the second embodiment, data transmission from the body ECU 20 to the central control center 80 during the execution of the abnormal content transmission process P31 is also performed in the same manner as in the first embodiment (see FIG. 16).

  However, the power line communication unit 7 and the power supply device 50 are replaced with the wireless communication unit 7X and the power supply device 50B, and the transmission processing T2 and T4 and the reply processing R2 and R4 of the wireless communication unit 7X and the power supply device 50B are performed by wireless communication. Is different.

(Effects etc.)
Thus, the vehicle antitheft device of the second embodiment in which the charging method is a contact charging method and the communication method is a wireless method has the same effect as that of the first embodiment. However, the presence / absence of the wireless communicable state cannot be recognized based on the presence / absence of the chargeable state.

<Embodiment 3>
FIG. 20 is a block diagram showing a configuration of a vehicle theft prevention system according to Embodiment 3 of the present invention. As shown in the figure, unlike the EV vehicle 1 of the first embodiment, the EV vehicle 1C is a battery 2 that stores electric power for driving a motor for traveling using a non-contact charging method described later (FIG. 22). (See). Furthermore, unlike Embodiment 1, EV vehicle 1C is connected to power feeding device 50C installed outside the vehicle via communication cable 70Y. That is, the connection is possible via the communication cable 70Y that connects between the connection part 16 of the EV vehicle 1C and the connection part 53Y of the power feeding device 50C.

  FIG. 21 is an explanatory view schematically showing an example of a non-contact charging method in the vehicle antitheft system of the third embodiment.

  As shown in the figure, the wireless power feeding unit 40C is separately provided as a component that complements a power feeding device 50C described later in order to charge the battery 2 of the EV vehicle 1C in a non-contact manner. Electric power is transmitted wirelessly and non-contactly from a power transmission coil 42 which is an embedded power transmission unit to a power reception coil 21 which is a power reception unit provided in the EV vehicle 1C. Although not shown, the wireless power feeding unit 40C is configured to be operable under the control of the power feeding device 50C using a communication function or the like.

  The wireless power feeding unit 40 </ b> C includes a power transmission coil 42, a high frequency power generation unit 43, and an AC power supply 44. On the other hand, the EV vehicle 1 </ b> C that is the power supply destination of the wireless power supply unit 40 </ b> C is provided with a power receiving coil 21, a charge control unit 3 </ b> X, and a rechargeable battery 2.

  The high frequency power generation unit 43 is a device that converts power supplied from an AC power supply 44 such as a commercial power supply into high frequency power and supplies the high frequency power to the power transmission coil 42. The power transmission coil 42 is embedded in the road surface as described above, and outputs a magnetic field whose magnetic force fluctuates at a high frequency when high-frequency power is supplied. The power transmission coil 42 supplies a non-contact power wirelessly to the power receiving coil 21 mounted on the EV vehicle 1 </ b> C by outputting a magnetic field whose magnetic force varies.

  On the other hand, the power receiving coil 21 mounted on the EV vehicle 1 </ b> C receives power from the power transmitting coil 42 in a non-contact state wirelessly. That is, the power receiving coil 21 is in a non-contact state from the power transmitting coil 42 between the power receiving coil 21 which is a power receiving unit provided in the EV vehicle 1C and the power transmitting coil 42 which is a power transmitting unit provided in the wireless power feeding unit 40C. To receive power.

  The charging control unit 3X operates under the control of the body ECU 20 (see FIG. 22), converts high-frequency power obtained by the power receiving coil 21 to DC power that meets the specifications of the battery 2, and converts the DC power to the battery. By charging the battery 2, the battery 2 is charged. For example, the charging control unit 3X is a rectifier circuit that rectifies high-frequency power, or an AC / DC converter circuit that converts a high-frequency AC voltage obtained by the power receiving coil 21 into a DC voltage that meets the specifications of the battery 2. Etc.

  As a wireless power transmission from the power transmission coil 42 to the power reception coil 21, for example, wireless power transmission by a resonance method can be considered. In this case, each of the power transmission coil 42 and the power reception coil 21 includes a self-resonant coil and an electromagnetic induction coil (both not shown). A rectenna array may be used instead of the power transmission coil 42 and the power reception coil 21 used as the power transmission unit and the power reception unit.

  Thus, in the third embodiment, unlike the first and second embodiments, a non-contact charging method (wireless power supply) that does not use the charging cable 70 as a charging method (predetermined charging method) is used. Adopted. In the following description, components having the same reference numerals appropriately operate in the same manner as in the first embodiment, and thus description thereof will be omitted as appropriate, and differences from the first embodiment will be mainly described.

  FIG. 22 is a block diagram showing a configuration of a vehicle antitheft device mounted on the EV vehicle 1C.

  In the EV vehicle 1C, instead of the charging port 1a and the charging control unit 3, a charging control unit 3X for controlling charging of the battery 2 from the wireless power feeding unit 40C and a power receiving coil 21 are provided, and a communication cable 70Y is provided. Embodiment 1 is different from Embodiment 1 in that a wired communication unit 7Y that performs wired communication between the EV vehicle 1 and the power feeding device 50C is mounted.

  The wired communication unit 7Y modulates and superimposes transmission data given from the body ECU 20 to perform wired transmission via the communication cable 70Y, and separates and demodulates the superimposed signal to demodulate the communication cable 70Y. The received data obtained through the control is given to the body ECU 20. When the body ECU 20 detects a vehicle abnormality such as intrusion into the EV vehicle 1C by the security function, the body ECU 20 uses the wired communication unit 7Y to detect the situation in the EV vehicle 1C such as the in-vehicle camera captured image data D30. Information indicating the abnormality content can be transmitted to the power feeding apparatus 50C by wired transmission via the communication cable 70Y.

  As described above, the third embodiment employs wireless communication as a communication method (predetermined communication method), and the wired communication unit 7Y performs wired communication with the power feeding device 50C via the communication cable 70Y.

(Abnormal content transmission process P31)
In the third embodiment, the abnormality content transmission process P31 is performed in the same manner as in the first embodiment (see FIG. 24), but is transmitted to the power feeding device 50C by wired communication by the wired communication unit 7Y performed via the communication cable 70Y. The communication method is different in that it is mainly. Furthermore, the operation of locking the plug portion 71 of the charging cable 70 performed in the first embodiment so as not to be removable from the charging port 1a is omitted from the abnormality content transmission process P31 and the vehicle-related prohibiting operation.

  FIG. 23 is a block diagram illustrating an internal configuration of the power feeding device 50C. The power supply device 50C is different in that a wired communication unit 54Y and a connection unit 53Y are provided instead of the power line communication unit 54 and the connection unit 53.

  The wired communication unit 54Y modulates and superimposes transmission data provided from the power supply control unit 51 of the EV vehicle 1C, thereby performing wired transmission via the connection unit 53Y and the communication cable 70Y, and via the communication cable 70Y. Received data obtained by separating and demodulating the superimposed signal obtained in this way is supplied to the power feeding control unit 51. The power feeding device 50C performs wired communication with the EV vehicle 1C using the wired communication unit 54Y, so that the power feeding control unit 51 can perform authentication processing, billing information transmission / reception processing, and the like. In addition, when the abnormality instruction information D40 is received from the EV vehicle 1C by wired communication, the power supply control unit 51 performs an alarm sound generation process by the alarm device 57 as necessary.

  Further, the power supply control unit 51 uses the LAN communication unit 55 for monitoring the power supply side when the in-vehicle camera captured image data D30 and the abnormality instruction information D40 are given from the EV vehicle 1C via the wired communication unit 54Y. The in-vehicle camera captured image data D30 and the abnormality instruction information D40 are transmitted to the centralized management center 80 together with the power feeding side camera captured image data D35 acquired from the camera 35.

  In the third embodiment, the contents of processing performed by the body ECU 20 in the abnormality occurrence state C3 are the same as those in the first embodiment (see FIG. 11).

  However, the contents of step S50 in FIG. 11 are different. In step S50, the body ECU 20 determines whether or not communication with respect to wired communication by the wired communication unit 7Y is possible. For example, the determination is made based on whether wired communication is possible with the power feeding device 50C using the wired communication unit 7Y.

  And when it is a communicable state (S50: YES), since the wire communication to 50 C of electric power feeders is possible, the abnormal content transmission process P31 (step S51) is performed and it is a communication impossible state (S50 :). NO) performs an abnormal alarm process P32 (step S51) because wired communication to the power feeding device 50C becomes impossible.

  FIG. 24 is a flowchart showing the procedure of the abnormal content transmission process P31 executed by the body ECU 20. As shown in the figure, in the third embodiment, since the contact-type charging method is adopted and the charging cable is not used, the charging cable locking process (step S11 in FIG. 11) is not executed. Hereinafter, steps S61 to S73 are executed in the same manner as the float of the first embodiment shown in FIG.

  However, the difference is that the data transmission to the power supply device 50C in step S66 and the transmission of information instructing the cancellation of the abnormality instruction information D40 in step S71 are performed by wired communication by the wired communication unit 7Y.

(Abnormal alarm processing P32)
In the third embodiment, the procedure of the abnormality alarm process P32 executed by the body ECU 20 is performed in the same manner as in the first embodiment (see FIG. 13).

  In the third embodiment, the procedure of the process performed by the power feeding device 50C in conjunction with the abnormality content transmission process P31 of the vehicle antitheft device is performed in the same manner as in the first embodiment (see FIG. 14).

  However, the difference is that the presence / absence of reception of abnormality instruction information D40 from the vehicle 1B in step S81 and the presence / absence of notification of cancellation of the abnormality instruction information D40 from the vehicle 1B in step S85 are determined based on the presence / absence of reception by wired communication.

  In the third embodiment, the communication frame structure shown in FIG. 15 has a communication frame structure in the wired communication of data used when transmitting the in-vehicle camera captured image data D30 and the abnormality instruction information D40.

  In the third embodiment, data transmission from the body ECU 20 to the centralized management center 80 during the execution of the abnormal content transmission process P31 is also performed in the same manner as in the first embodiment (see FIG. 16).

  However, the power line communication unit 7 and the power feeding device 50 are replaced with the wired communication unit 7Y and the power feeding device 50C, the transmission processing T2 and T4 and the reply processing R2 and R4 of the wired communication unit 7Y and the power feeding device 50C use the communication cable 70Y. The difference is that it is performed by wired communication.

(Effects etc.)
Thus, the vehicle antitheft device of the third embodiment in which the charging method is a non-contact charging method and the communication method is a wired method has the same effect as that of the first embodiment. However, the presence / absence of a communicable state of wired communication by the communication cable 70Y cannot be recognized based on the presence / absence of the chargeable state.

<Embodiment 4>
FIG. 25 is a block diagram showing a configuration of a vehicle theft prevention system according to Embodiment 4 of the present invention. As shown in the figure, unlike the EV vehicle 1 of the first embodiment, the EV vehicle 1D accumulates electric power for driving the motor for traveling using the non-contact charging method as in the third embodiment. The battery 2 (see FIG. 27) is charged. Furthermore, unlike Embodiment 1, EV vehicle 1D performs wireless communication with power supply device 50D installed outside the vehicle using wireless communication unit 7Z.

  FIG. 26 is an explanatory view schematically showing an example of a non-contact charging method in the vehicle antitheft system of the fourth embodiment.

  As shown in the figure, similarly to the wireless power feeding unit 40C, the wireless power feeding unit 40D is provided separately as a component that complements a power feeding device 50D described later in order to charge the battery 2 of the EV vehicle 1D in a non-contact manner. The power is transmitted wirelessly from the power transmission coil 42 embedded in the road surface to the power reception coil 21 provided in the EV vehicle 1D. Although not shown, the wireless power feeding unit 40D is configured to be operable under the control of the power feeding device 50D using a communication function or the like (a wireless communication unit 47 and an antenna 48 described later).

  In the EV vehicle 1D, the wireless communication unit 7Z disposed close to the power receiving coil 21 can communicate with the wireless communication unit 47 embedded in the road surface provided in the wireless power feeding unit 40D via the antenna 8Z and the antenna 48. The wireless communication unit 47 is provided to be able to wirelessly transmit to the power feeding device 50D via the antenna 48. Therefore, the wireless communication unit 7 </ b> Z can perform wireless transmission with the power feeding device 50 through the wireless communication unit 47. Since the other configuration is the same as that of the third embodiment shown in FIG. 21, the same parts as those of the EV vehicle 1C and the wireless power feeding unit 40C are denoted by the same reference numerals, and the description thereof is omitted.

  Thus, unlike Embodiment 1 and Embodiment 2, Embodiment 4 does not use charging cable 70 as a charging method (predetermined charging method), and is the same non-contact charging method as Embodiment 3 ( Wireless power supply). In the following description, components having the same reference numerals appropriately operate in the same manner as in the first embodiment, and thus description thereof will be omitted as appropriate, and differences from the first embodiment will be mainly described.

  FIG. 27 is a block diagram showing a configuration of a vehicle antitheft device mounted on the EV vehicle 1D.

  In the EV vehicle 1D, a charging control unit 3X (similar to the third embodiment) that controls charging of the battery 2 from the wireless power feeding unit 40D, and wireless between the EV vehicle 1 and the power feeding device 50D using the wireless power feeding unit 40D as a relay station. The difference from the first embodiment is that a wireless communication unit 7Z that performs communication is mounted.

  The radio communication unit 7Z performs radio transmission to the radio communication unit 47 by modulating and superimposing transmission data given from the body ECU 20 via the antenna 8Z, and separates and demodulates the superimposed signal. Thus, the reception data obtained via the antenna 8Z is relayed through the wireless communication unit 47 in the wireless power feeding unit 40D and given to the body ECU 20. When the body ECU 20 detects a vehicle abnormality such as intrusion into the EV vehicle 1D by the security function, the body ECU 20 uses the wireless communication unit 7Z to detect the situation in the EV vehicle 1D such as the in-vehicle camera captured image data D30. Information indicating the content of the abnormality can be transmitted to the power feeding device 50D by wireless transmission using the wireless communication unit 47 as a relay station.

  As described above, the fourth embodiment employs wireless communication as a communication method (predetermined communication method), and the wireless communication unit 7Z performs wireless communication with the power supply apparatus 50D using the wireless communication unit 47 as a relay station. .

(Abnormal content transmission process P31)
In the fourth embodiment, the abnormality content transmission process P31 is performed in the same manner as in the first embodiment, but mainly transmitted to the power feeding device 50D by wireless communication by the wireless communication unit 7Z that performs the wireless communication unit 47 as a relay station. The communication method is different. Furthermore, the operation of locking the plug portion 71 of the charging cable 70 performed in the first embodiment so as not to be removable from the charging port 1a is omitted from the abnormality content transmission process P31 and the vehicle-related prohibiting operation.

  FIG. 28 is a block diagram illustrating an internal configuration of the power feeding device 50D. The power feeding device 50D is different in that a wireless communication unit 54X and an antenna 58 are provided instead of the power line communication unit 54 and the connection unit 53.

  The wireless communication unit 54X modulates and superimposes transmission data provided from the power supply control unit 51 of the EV vehicle 1D, thereby performing wireless transmission via the antenna 58 and relaying the wireless communication unit 47 to the EV vehicle 1D. To the wireless communication unit 7Z. In addition, the wireless communication unit 54X relays the reception data obtained by relaying the wireless communication unit 47 from the wireless communication unit 7Z and finally deriving and demodulating the superimposed signal obtained via the antenna 58. This is given to the power supply control unit 51. By performing the above-described wireless communication by the wireless communication unit 54X between the power supply device 50D and the EV vehicle 1D, the power supply control unit 51 can perform an authentication process or a charging information transmission / reception process. In addition, when the abnormality instruction information D40 is received from the EV vehicle 1D by wireless communication, the power supply control unit 51 performs an alarm sound generation process by the alarm device 57 as necessary.

  In addition, when the in-vehicle camera captured image data D30 and the abnormality instruction information D40 are given from the EV vehicle 1D via the wireless communication unit 54X by the wireless communication, the power supply control unit 51 uses the LAN communication unit 55 for monitoring the power supply side. The in-vehicle camera captured image data D30 and the abnormality instruction information D40 are transmitted to the centralized management center 80 together with the power feeding side camera captured image data D35 acquired from the camera 35.

  In the fourth embodiment, the contents of processing performed by the body ECU 20 in the abnormality occurrence state C3 are the same as those in the first embodiment (see FIG. 11).

  However, the contents of step S50 in FIG. 11 are different. In step S50, the body ECU 20 determines whether or not communication is possible with respect to wireless communication by the wireless communication unit 7Z. For example, the determination is made based on whether or not wireless communication using the wireless communication unit 47 as a relay station with the power supply device 50D using the wireless communication unit 7Z is possible.

  And when it is a communicable state (S50: YES), since radio | wireless communication to electric power feeder 50D is possible, abnormal content transmission process P31 (step S51) is performed and it is a communication impossible state (S50 :). NO) performs wireless communication with the power feeding device 50D, and therefore executes the alarm processing P32 at the time of abnormality (step S51).

  The procedure of the abnormal content transmission process P31 executed by the body ECU 20 is performed in the same manner as in the third embodiment (see FIG. 24). However, the difference is that the data transmission to the power supply apparatus 50D in step S66 and the transmission of information instructing the cancellation of the abnormality instruction information D40 in step S71 are performed by wireless communication by the wireless communication unit 7Z.

(Abnormal alarm processing P32)
In the fourth embodiment, the procedure of the abnormality warning process P32 executed by the body ECU 20 is performed in the same manner as in the first embodiment (see FIG. 13).

  In the fourth embodiment, the procedure of the process performed by the power feeding device 50D in conjunction with the abnormality content transmission process P31 of the vehicle antitheft device is performed in the same manner as in the first embodiment (see FIG. 14).

  However, the difference is that the presence / absence of reception of abnormality instruction information D40 from the vehicle 1B in step S81 and the presence / absence of notification of cancellation of the abnormality instruction information D40 from the vehicle 1B in step S85 are determined based on the presence / absence of reception by wireless communication.

  In the fourth embodiment, a communication frame structure in wireless communication of data used at the time of data transmission of the in-vehicle camera captured image data D30 and the abnormality instruction information D40 is adopted by the communication frame 90 shown in FIG.

  In the fourth embodiment, data transmission from the body ECU 20 to the central control center 80 during the execution of the abnormality content transmission process P31 is also performed in the same manner as in the first embodiment (see FIG. 16).

  However, the power line communication unit 7 and the power supply device 50 are replaced with the wireless communication unit 7Z and the power supply device 50D, the transmission processing T2 and T4 and the reply processing R2 and R4 of the wireless communication unit 7Z and the power supply device 50D relay the wireless communication unit 47. The difference is that it is performed by wireless communication with a station.

(Effects etc.)
As described above, the vehicle antitheft device according to the fourth embodiment in which the charging method is a non-contact charging method and the communication method is a wireless method (the wireless communication unit 7Z is separated from the power receiving coil 21). The same effect as in the first mode is obtained. However, the presence / absence of the wireless communicable state cannot be recognized based on the presence / absence of the chargeable state.

<Embodiment 5>
FIG. 29 is a block diagram showing a configuration of a vehicle theft prevention system according to the fifth embodiment of the present invention. As shown in the figure, EV vehicle 1E is different from EV vehicle 1 of the first embodiment in order to drive a motor for traveling using a non-contact charging method as in the third and fourth embodiments. The battery 2 (see FIG. 31) that stores the electric power is charged. Furthermore, unlike Embodiment 1, EV vehicle 1E performs wireless communication with power feeding device 50E installed outside the vehicle using power receiving rectenna 21Z with a communication function that also functions as a wireless communication unit.

  FIG. 30 is an explanatory view schematically showing an example of a non-contact charging method in the vehicle antitheft system of the fifth embodiment.

  As shown in the figure, similarly to the wireless power supply unit 40C and the wireless power supply unit 40D, the wireless power supply unit 40E is separated to complement a power supply device 50E described later in order to charge the battery 2 of the EV vehicle 1E in a non-contact manner. The power transmission rectenna 42Z with a communication function that is embedded in the road surface is wirelessly transmitted to the power reception rectenna 21Z with a communication function provided in the EV vehicle 1E. . Although not shown, the wireless power feeding unit 40E is configured to be operable under the control of the power feeding device 50E using a communication function or the like (such as a power receiving rectenna 21Z with a communication function).

  Furthermore, the power receiving rectenna 21Z with the communication function can communicate with the power transmitting rectenna 42Z with the communication function, and the power transmitting rectenna 42Z with the communication function can wirelessly transmit to the power feeding device 50E. Therefore, the power receiving rectenna 21 </ b> Z with a communication function also functions as a wireless communication unit that relays the power transmitting rectenna 42 </ b> Z with a communication function and performs wireless transmission with the power feeding device 50. Since the other configuration is the same as that of the third embodiment shown in FIG. 21, the same parts as those of the EV vehicle 1C and the wireless power feeding unit 40C are denoted by the same reference numerals, and the description thereof is omitted.

  Thus, unlike Embodiment 1 and Embodiment 2, Embodiment 5 does not use charging cable 70 as a charging method (predetermined charging method), and is the same as in Embodiment 3 and Embodiment 4. The contact-type charging method (wireless power supply) is adopted. In the following description, components having the same reference numerals appropriately operate in the same manner as in the first embodiment, and thus description thereof will be omitted as appropriate, and differences from the first embodiment will be mainly described.

  FIG. 31 is a block diagram showing a configuration of a vehicle antitheft device mounted on the EV vehicle 1E.

  In EV vehicle 1E, EV control is performed using charging control unit 3X (similar to the third embodiment) for controlling charging of battery 2 from wireless power feeding unit 40E and wireless power feeding unit 40E (power transmission rectenna 42Z with a communication function) as a relay station. The difference from the first embodiment is that a power receiving rectenna 21Z with a communication function for performing wireless communication between the vehicle 1 and the power feeding device 50E is mounted.

  The power receiving rectenna 21Z with the communication function modulates and superimposes the transmission data given from the body ECU 20, thereby performing wireless transmission to the power transmitting rectenna 42Z with the communication function and separating and demodulating the superimposed signal. Thus, the reception data obtained by relaying the power transmission rectenna 42Z with the communication function is given to the body ECU 20. When the body ECU 20 detects a vehicle abnormality such as intrusion into the EV vehicle 1E by the security function, the body ECU 20 uses the power receiving rectenna 21Z with a communication function, so that the in-vehicle camera captured image data D30 and the like in the EV vehicle 1E Information indicating the abnormal content such as the situation can be transmitted to the power feeding device 50E by wireless transmission using the power transmitting rectenna 42Z with a communication function as a relay station.

  As described above, the fifth embodiment employs wireless communication as the communication method (predetermined communication method), and the power receiving rectenna 21Z with the communication function communicates with the power feeding device 50E using the power transmitting rectenna 42Z with the communication function as a relay station. It also functions as a wireless communication unit that performs wireless communication between them.

(Abnormal content transmission process P31)
In the fifth embodiment, the abnormality content transmission process P31 is performed in the same manner as in the first embodiment. However, the power transmission rectenna 42Z with a communication function is used as a relay station to the power feeding device 50E by wireless communication using the power receiving rectenna 21Z with a communication function. The communication method is different in that it is mainly transmitted. Furthermore, the operation of locking the plug portion 71 of the charging cable 70 performed in the first embodiment so as not to be removable from the charging port 1a is omitted from the abnormality content transmission process P31 and the vehicle-related prohibiting operation.

  The internal configuration of the power supply device 50E is the same as that of the power supply device 50D of the fourth embodiment. The power supply device 50E includes a wireless communication unit 54X and a power line communication unit 54 and a connection unit 53 (see FIG. 7) of the first embodiment. The difference is that an antenna 58 is provided (see FIG. 28).

  However, in the fifth embodiment, the communication target with the wireless communication unit 54 is the power receiving rectenna 21Z with the communication function of the EV vehicle 1E with the power transmitting rectenna 42Z with the communication function as a relay.

  In the fifth embodiment, the processing contents performed by the body ECU 20 in the abnormality occurrence state C3 are the same as those in the first embodiment (see FIG. 11).

  However, the contents of step S50 in FIG. 11 are different. In step S50, the body ECU 20 determines whether or not communication is possible for wireless communication by the power receiving rectenna 21Z with a communication function. For example, the determination is made based on whether wireless communication using the power transmission rectenna 42Z with the communication function as a relay station is possible with the power feeding device 50E using the power reception rectenna 21Z with the communication function.

  And when it is a communicable state (S50: YES), since the wireless communication to the electric power feeder 50E is possible, the abnormal content transmission process P31 (step S51) is performed and it is a communication impossible state (S50 :). NO) executes the alarm processing P32 at the time of abnormality (step S51) because wireless communication with the power feeding device 50E becomes impossible.

  The procedure of the abnormal content transmission process P31 executed by the body ECU 20 is performed in the same manner as in the third embodiment (see FIG. 24). However, the difference is that the data transmission to the power supply device 50E in step S66 and the transmission of information instructing the cancellation of the abnormality instruction information D40 in step S71 are performed by wireless communication by the power receiving rectenna 21Z with a communication function.

(Abnormal alarm processing P32)
In the fourth embodiment, the procedure of the abnormality warning process P32 executed by the body ECU 20 is performed in the same manner as in the first embodiment (see FIG. 13).

  In the fifth embodiment, the procedure of the process performed by the power feeding device 50E in conjunction with the abnormality content transmission process P31 of the vehicle antitheft device is performed in the same manner as in the first embodiment (see FIG. 14).

  However, whether or not the abnormality indication information D40 is received from the vehicle 1B in step S81 and whether or not the abnormality indication information D40 is released from the vehicle 1B in step S85 are received by wireless communication using the power receiving rectenna 21Z with a communication function. The point of determination differs depending on whether or not there is.

  In the fifth embodiment, a communication frame structure in wireless communication of data used at the time of data transmission of the in-vehicle camera captured image data D30 and the abnormality instruction information D40 is adopted by the communication frame 90 shown in FIG.

  In the fifth embodiment, data transmission from the body ECU 20 to the centralized management center 80 during the execution of the abnormality content transmission process P31 is also performed in the same manner as in the first embodiment (see FIG. 16).

  However, the power line communication unit 7 and the power feeding device 50 are replaced with the power receiving rectenna 21Z and the power feeding device 50E with communication function, the power receiving rectenna 21Z with communication function, the transmission processing T2 and T4 of the power feeding device 50E, and the reply processing R2 and R4. The difference is that it is performed by wireless communication.

(Effects etc.)
As described above, the vehicle antitheft device according to the fifth embodiment in which the charging method is the non-contact charging method and the communication method is the wireless method (integrating the charging / communication function by the power receiving rectenna 21Z with the communication function) is implemented. The same effects as in the first embodiment are obtained. However, the presence / absence of the wireless communicable state cannot be recognized based on the presence / absence of the chargeable state.

<Others>
In the above-described embodiment, the EV vehicle 1 is configured to include the single hall element 9. However, the present invention is not limited to this, and a configuration in which a plurality of hall elements 9 are mounted at appropriate positions of the EV vehicle 1 is also possible. Good. In this case, if any of the hall elements 9 detects a change in vehicle height that exceeds the threshold, it can be determined that there is an intruder, and the accuracy of intrusion detection can be further increased. is there.

  Moreover, although the electric power feeder 50 (50B-50E) was set as the structure which outputs the alarm sound by the alarm device 57, when the notification from the EV vehicle 1 (1B-1E) is given, it does not restrict to this. In addition, the alarm may be not only an alarm sound but also a visual alarm such as lamp lighting.

  When a failure occurs in the hall element 9, for example, in the case of the hall element failure occurrence timing t11 in FIG. 3, the headlight angle adjustment process immediately prohibits the use of the hall element 9 in the vehicle abnormality detection process. Further, in the case of the hall element failure occurrence timing t12, the vehicle abnormality detection process is performed using another possible determination method without using the hall element 9, and the headline angle adjustment process is not performed thereafter.

  Further, when at least a part of the monitoring camera group 30 breaks down, it may be immediately detected that the vehicle is abnormal regardless of the detection voltage of the hall element 9. For example, when a new failure is detected only in the front monitoring camera 31 in the monitoring camera group 30 that is normal during the warning state C2, the state may be immediately shifted to the abnormal state occurrence state C3. In the case of the above example, the in-vehicle camera imaging data D32 and the rear camera image imaging data D33 obtained from the in-vehicle monitoring camera 32 and the rear monitoring camera 33 operating normally are transmitted to the power supply device 50 as in-vehicle camera imaging image data D30. Will be.

  Further, in the above-described embodiment, the EV vehicle 1 (1B to 1E) is shown as an example. However, an external power supply device such as an HEV car is connected to a battery using a contact charging method or a non-contact charging method. Of course, the present invention can be applied to all plug-in type vehicles that are charged.

  Further, when the EV vehicle 1 has a GPS (Global Positioning System) function, the position information is included in the abnormality indication information D40 and transmitted to the power feeding device 50, or at the power feeding device 50 or the central management center 80 side. Further, processing such as recognizing the position of the EV vehicle 1 where the vehicle abnormality has occurred by GPS positioning may be performed together.

  It should be noted that the present invention can be freely combined with each other within the scope of the invention, and each embodiment can be appropriately modified or omitted.
