Abstract

<P>PROBLEM TO BE SOLVED: To provide a receiving device for a vehicle which can remotely control a device of the vehicle targeted for operation by using a mobile communication network while preventing a battery of the vehicle from going dead, and can effectively guard against theft of the vehicle. <P>SOLUTION: A vehicle-mounted control part of a communication module extends the ON state of the power of a wireless part for a fixed period of time A (a week) when ACC of an ignition switch is turned to the OFF position. When a theft-surveillance ECU detects a dishonest act to the vehicle, a theft alarm is given to a user by way of a center (in Fig. (b) (d)). The control part extends the ON state of the power of the wireless part for a fixed period of time B (two days), and provides a notice of suspension of standby when the fixed period of time B expires. In this case, the reason for setting the fixed period of time B (two days) shorter than the fixed period of time A (a week) is to deal with the circumstances that the stolen vehicles are illegally transported overseas within a short time in many cases, thus the period of time for effectively dealing with the circumstances is extremely short. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a vehicle receiver that controls an operation target device in response to an operation request signal received through a mobile communication network.

Conventionally, as shown in Patent Document 1, devices for remotely operating a predetermined device of a vehicle such as unlocking a door and starting an engine using a keyless entry, a smart entry, a remote control engine starter, and the like have been provided.
Japanese Patent Laid-Open No. 10-21868

However, since these radio systems use weak radio waves and power-saving radio waves, there is a problem that remote control is not possible when the user is at a long distance.
In addition, when remote operation is performed using a mobile communication network such as a mobile phone network or a PHS network, the remote operation is possible even if the user is at a long distance, but the current consumption of the communication module is keyless entry, smart Compared to entry, remote control engine starter, etc., it is much larger and there is a risk that the battery of the vehicle will run out.

  On the other hand, an anti-theft device is provided that notifies an administrator of alarm information such as theft monitoring, location information, etc. using a mobile phone network or a PHS network, but this does not accept remote operation from the administrator. Therefore, there is a problem that the function of the wireless unit is stopped and remote control is not possible.

  As a means for solving such a problem, when the anti-theft device operates, it is possible to extend the function of the wireless unit and accept remote operation from the administrator. In many cases, vehicles are illegally transported overseas, and immediate urgency is important. Therefore, simply extending the function of the radio unit cannot effectively deal with vehicle theft.

  The present invention has been made in view of the above circumstances, and an object thereof is to remotely control the operation target device of the vehicle by using the mobile communication network while preventing the battery from rising, and is effective for theft of the vehicle. An object of the present invention is to provide a vehicular receiving apparatus that can cope with the above.

According to the first aspect of the present invention, when the administrator performs a remote operation to control the operation target device of the vehicle, the wireless means receives the operation request signal, so the control means adds the operation request signal received by the wireless means. The operation target device is controlled accordingly.
When the driver gets off, the getting-off estimating means estimates that the driver has got off. Then, since the control means extends the standby state of the wireless means until the first predetermined period elapses in order to permit the remote operation, the operation target device can be controlled from the remote place during that time.

  Here, since the wireless means consumes a large amount of power, the control means operates the power saving means when the first predetermined period ends. Thereby, since a radio | wireless means transfers to a power saving state, power consumption can be achieved and consumption of a battery can be suppressed.

Now, when the wireless means is in a power saving state and the vehicle is fraudulent, the monitoring means detects the fraud, so the control means notifies the administrator of this. The wireless unit is set in a standby state until a second predetermined period shorter than the first predetermined period elapses. As a result, the device to be operated can be remotely operated only for a short period of time of the second predetermined period. For example, in recent vehicle theft techniques, vehicles are often transported illegally overseas, and immediate urgency is important. Even if the unauthorized operation is threatened by remote operation or the use of the vehicle is restricted, it is possible to effectively cope with the situation that the period during which it is effective is short.
And when the 2nd predetermined period is complete | finished, since a radio | wireless means transfers to a power saving state, power consumption can be suppressed and consumption of a battery can be suppressed.

  By the way, since the invention of claim 1 is characterized in that the second predetermined period is set shorter than the first predetermined period, for example, an illegal act is detected at an early stage of the first predetermined period. In this case, if the power saving means is operated after the second predetermined period elapses, the standby state of the wireless means becomes shorter than the operation of the power saving means after the first predetermined period elapses. There is a possibility that the wireless means may shift to the power saving state while tracking the vehicle that has been used. Even if an illegal act is detected during the first predetermined period, if the count of the first predetermined period is continued as it is, the remaining period of the first predetermined period is small. There is a possibility that the wireless means may shift to the power saving state while tracking the vehicle that has been used.

  Therefore, according to the invention of claim 2, when an illegal act is performed on the vehicle during the first predetermined period, the longer period is executed by comparing the remaining period with the second predetermined period. Thus, it is possible to extend the standby state of the wireless means while preventing the battery from going up.

  According to the invention of claim 3, since the stand-by state of the wireless means is further extended by the first predetermined period when the illegal act is performed on the vehicle during the first predetermined period. Similarly to the invention of the first aspect, it is possible to extend the standby state of the wireless means while preventing the battery from going up.

  According to the fourth aspect of the present invention, when the administrator remotely operates the vehicle for fraud, there is a high possibility that the administrator will continue to remotely operate the vehicle. Is further extended for a second predetermined period. Thereby, since the operation target device can be remotely operated only for a short period of the second predetermined period, it is possible to threaten an unauthorized person or limit the use of the vehicle only by a short period of time.

  According to the fifth aspect of the present invention, the wireless means receives the extension request signal from the administrator even if the administrator is notified that the wireless means is to be stopped when the first or second predetermined period has elapsed. If not, the wireless means shifts to the power saving state by the power saving means, so that power consumption can be reduced and battery consumption can be suppressed. On the other hand, when the extension request signal is received from the administrator, the standby state of the wireless means is further extended for a third predetermined period. Thereby, since the operation target device can be remotely operated, it is possible to threaten an unauthorized person or restrict the use of the vehicle by remote operation. In this case, since the third predetermined period is set shorter than the first predetermined period, it is possible to extend the standby state of the wireless unit only during a period when the operation request signal is highly likely to be received from the administrator.

According to the sixth aspect of the invention, when the driver gets off, it is normal to turn off the vehicle power supply means, so the getting-off estimating means can reliably estimate that the driver has got off.
According to the seventh aspect of the present invention, when the vehicle is turned off and the vehicle is locked, the getting-off estimating means can reliably estimate that the driver has got off the vehicle.

According to the invention of claim 8, even if the stolen vehicle is located in an environment where communication with the outside is impossible, since the counting of the first predetermined period and the second predetermined period is stopped during that period, The means does not enter a power saving state and can reliably cope with theft.
According to the ninth aspect of the present invention, it is possible to prevent in advance problems caused by the control means operating inadvertently, such as during vehicle inspection.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a block diagram schematically showing the configuration of the entire system. In FIG. 1, the present system enables a predetermined operation target mounted on a vehicle to be remotely operated. As a means for this, a communication module (corresponding to a vehicle remote control device) 1 is mounted on the vehicle. ing. This communication module 1 has a mobile phone or PHS function, and sends an operation request signal from a user (administrator) mobile phone (or PC (Personal Computer)) 3 through a center 2 to a mobile phone network (mobile). It is possible to control a predetermined operation target ECU (corresponding to an electronic control unit, operation target device) 4 mounted on the vehicle by the operation request signal. Thereby, the user can remotely control a predetermined operation target of the vehicle.

  The communication module 1 corresponds to a power supply unit 5 that generates a predetermined voltage in response to power supplied from a vehicle battery, and a control unit having a counter 6 (control means, power saving means, getting-off estimation means, vehicle power supply monitoring means) ) 7 and a wireless unit (corresponding to wireless means) 8. The control unit 7 performs communication through the wireless unit 8 and manages the operation of the wireless unit 8 as described later based on a signal from a theft monitoring ECU (corresponding to a monitoring unit) 9 mounted on the vehicle. The communication module 1 is supplied with power directly from a battery, and can operate even when an ignition switch (corresponding to vehicle power supply means) 10 is in an ACC-off state.

  Control targets of the operation target ECU 4 include hazard extinction / lighting, headlight lighting / extinguishing, position light blinking / extinguishing, interior lighting / extinguishing, engine start / stop, window opening / closing / partial opening, door lock / unlocking. Lock, sunroof open / close / partial open, air conditioner start / stop, etc.

The theft monitoring ECU 9 monitors the abnormality of the vehicle by various sensors, and notifies the communication module 1 of the abnormality when detecting the abnormality.
The center 2 manages communication between the communication module 1 and the user's mobile phone (or PC) 3 through the base station 11 and opens a WEB site accessible from the user's mobile phone (or PC) 3. ing.

  As described above, the control unit 7 of the communication module 1 basically controls the predetermined operation target ECU 4. In this embodiment, the wireless unit 8 as described later in connection with the present invention is used. Has power saving function.

Next, the operation of the above configuration will be described.
A person who wants to use this system applies to the center 2 for membership registration. In the center 2, when the user applies for member registration, data for personal authentication is registered in the member management WEB site corresponding to the user. In this case, when both the telephone number of the mobile phone and the mail address of the PC are registered, the priority order of contact can be set. Also, an ID and password for personal authentication are registered at the same time.

  Here, since the communication module 1 is directly supplied with power from the battery, it operates even when the ignition switch 10 is in the ACC off state. When the ACC is off, the control unit 7 of the communication module 1 operates. Performs the following operations.

FIG. 2 shows operations related to the present invention among the operations of the control unit 7 of the communication module 1. In FIG. 2, the control unit 7 of the communication module 1 monitors the reception of the ACC off signal from the ignition switch 10 (S101).
In this embodiment, the judgment of getting off is made only by the ACC off signal, but the getting off judgment may be made not only by the ACC off signal but also by locking the vehicle by the keyless entry device or the smart entry device. good.

When the user turns off the ignition switch 10 to get off the vehicle, the control unit 7 receives the ACC off signal (S101: YES), and thus starts the counter A for a certain period A (one week) (S102). .
Now, after the user gets off the vehicle for a while, the user may notice that “I forgot to turn off the hazard”. For example, when stopping at a department store parking lot, the hazard is blinked and the intention to park in the following vehicle is reported, but when the user gets off the hazard is turned off, and this is noticed during shopping at the department store.

  In such a case, the control unit 7 of the communication module 1 monitors whether or not the hazard blinking state has continued for a certain time (1 minute) after the ACC is turned off. Notification is made (see FIG. 4A). The center / user means that the user is notified via the center, and so on.

  Notification to the user can be made in real time by sending a predetermined mail to the user's mobile phone (or PC) 3 or the like. If it is selected to notify only the center 2, it is registered in the center 2. A notification destination such as a mobile phone (or PC) 3 can be selected by the user registering in the center 2.

  In this case, considering that a request for returning the vehicle state to a normal state is received from the user by remote operation, remote confirmation from the user is performed for a certain period A (for example, one week) from when the user gets off the vehicle (ACC off). Always allow. That is, the wireless unit 8 of the communication module 1 always stands by for one week after the ACC is turned off.

In the following description, the operation by the mobile phone 3 that receives the notification from the center 2 will be described, but the operation on the PC is basically the same.
FIG. 5 shows an example of a warning screen by the mobile phone 3. As shown in FIG. 5, the liquid crystal display unit 12 of the cellular phone 3 displays a message “The customer's car is in the following state! Hazard is blinking” as a notification from the center 2. Is done.

As for remote operation from the user, it is possible to perform remote operation of the vehicle by browsing a predetermined WEB site of the Internet established by the center 2 from the mobile phone 3 and selecting an operation item. ing.
FIG. 6 shows an example of an operation screen from the mobile phone 3 to a predetermined WEB site on the Internet. In FIG. 6, in addition to the warning message described above, the message “Please operate from the“ remote control ”button” is displayed on the liquid crystal display unit 12 of the mobile phone 3. The “remote operation” button 13 is displayed.

When the user wishes to remotely operate the vehicle, the “remote operation” button 13 is touch-operated.
When the “remote operation” button 13 is touched, the mobile phone 3 accesses a URL (Uniform Resource Locator) registered corresponding to the “remote operation” button 13. As a result, the remote operation screen is displayed on the liquid crystal display unit 12 when the user moves to the WEB site for remote operation and the identity is specified by a predetermined authentication method.

  FIG. 7 shows a remote operation screen by the mobile phone 3. In FIG. 7, the remote operation screen displays a message “You can remotely control your car. Select the button you want to operate and press“ OK ”.” The state is displayed in a selectable state, and the “OK” button 14 is further displayed.

  Accordingly, when the user notices that the hazard lamp has been forgotten to turn off in a short time after getting off the vehicle, the “determine” button 14 is touch-operated with the hazard stop selected. As a result, the radio unit 8 receives a hazard extinguishing request instructing to turn off the hazard lamp (see FIG. 4A), and the control unit 7 instructs the hazard blink control ECU to extinguish the hazard. The blinking of the lamp can be stopped remotely.

  When the control unit 7 of the communication module 1 waits for a certain period A (one week) from the last vehicle stop (ACC off) without receiving a remote operation from the user (S103: YES), the center / After notifying the user that the wireless unit 8 is to be stopped, a counter C (for example, 2 hours) is started (S105), and remote operation from the center / user is permitted. In this case, the reason why the counter C is set to be as short as 2 hours is that the center / user notified to stop the radio unit 8 usually responds in a relatively short time.

  FIG. 8 shows a standby stop notification screen by the mobile phone 3. In FIG. 8, the liquid crystal display unit 12 of the mobile phone 3 displays “The communication module standby is stopped because the battery of the customer's car may run out. If you want to extend the standby, press the“ Extend ”button. In addition to the message “Please press”, a warning message “There is a possibility that the battery of the car may rise if the standby of the communication module is extended” is displayed, and an “Extend” button 15 is further displayed.

  When the counter C is terminated without a request from the center / user (S107: YES), the control unit 7 stops standby of the wireless unit 8 (S108) and prevents the vehicle battery from running out. This is because there is a low possibility that the state of the vehicle will be anxious after the vehicle is left for a week. Stopping in this case is to stop the power supplied to the wireless unit 8 in addition to shutting off the power to the wireless unit 8 or to stop the clock supplied to the wireless unit 8 or to put the wireless unit 8 in the sleep state. Various methods can be implemented as long as power consumption can be reduced.

On the other hand, when the user touches the “extend” button 15 to extend the standby, the control unit 7 receives a standby continuation request from the center / user until the count of the counter C is completed (S106: YES), a counter D (for example, 2 days) is started (S109), and the standby is extended for a certain period D (2 days). In this case, the reason why the fixed period D is set shorter than the fixed period A is that, when a standby extension request is received, there is a high possibility that the remote control is performed within a relatively short period.
If an operation request is received from the center / user by the end of the counter D (S110: YES), the process proceeds to S109 and the counter D is started again, thereby extending the standby state of the wireless unit 8 for a certain period D. At the same time, this is notified by the mobile phone 3 (see FIG. 9).

  On the other hand, when the fixed period D ends without an operation request from the center / user (S111: YES), the center / user is notified that the radio unit 8 is stopped (S112), and then the counter The operation of the wireless unit 8 is extended by C (S113). When an extension request is received (S114: YES), the operation of the wireless unit 8 is extended by shifting to step S109, and the extension request is not received. When C ends (S115: YES), the wireless unit 8 is stopped (S116).

  By the operation as described above, when a certain period A (one week) has elapsed since the driver finally got off the vehicle, the center / user is notified that the radio unit 8 will be stopped, and for a certain period of time. If there is no extension request from the center / user in C, or there is no operation request within a certain period D even if there is an extension request from the center / user, the wireless unit 8 is stopped. When there is no expectation of receiving an operation request from the user, it is possible to prevent the battery from going up by stopping the radio unit 8 with high power consumption.

  By the way, as described above, when the possibility of remote operation from the center / user is low in the parking state of the vehicle, it is possible to prevent the battery from going up by stopping the wireless unit 8, but the vehicle is illegal. In this case, it is desirable that the wireless unit 8 be in a standby state to enable remote operation.

  However, if the operation period of the radio unit 8 is extended by a certain period A (one week) that is an extension period of the standby state of the radio unit 8 when the ACC is off, for example, a situation in which a stolen vehicle is transported overseas In addition, for a situation where a short-term response is required, the available period is too long, and the center / user may not be able to respond appropriately.

Therefore, in this embodiment, the center / user can appropriately cope with the case where the vehicle is cheated as follows.
That is, when the theft monitoring ECU 9 detects a vehicle theft or vehicle mischief, the theft monitoring ECU 9 generates a theft interrupt to the control unit 7.

When a theft interrupt occurs, the control unit 7 executes a theft interrupt process.
FIG. 3 shows a theft interrupt process of the control unit 7. In FIG. 3, the control unit 7 notifies the center / user of theft (S201), resets the counter (S202), starts the counter B (for example, 2 days) (S203), and performs a fixed period B ( It is monitored whether or not an operation request is received from the center / user by the end of (2 days) (S204). In this case, the fixed period B is set to 2 days and shorter than the fixed period A (one week). For example, in the recent vehicle theft, there are cases where the stolen vehicle is illegally transported overseas. In many cases, immediate urgency is important, and when a warning signal is sent from the vehicle to the center / user, the center / user performs remote operations such as horn ringing, hazard flashing, engine start prohibition, etc. in order to threaten unauthorized persons. This is to effectively cope with the fact that even if requested, the period during which it is effective is extremely short.

As described above, functions to notify the user from the vehicle when security such as vehicle theft occurs include regular notification of vehicle current location information, vehicle ACC on, vehicle operation state notification such as engine start, and the like.
In addition, functions that can remotely operate the vehicle when security such as vehicle theft occurs include engine start prohibition / cancellation, hazard blinking, headlight lighting, position light lighting, horn ringing, and the like.

  When a user sends a warning signal from the vehicle to the center during a certain period A or after a certain period A (one week) has elapsed since the user last got off the vehicle, b) and (d)), since there is a high possibility that a remote operation request such as horn ringing, hazard flashing, engine start prohibition, etc. will come from the center / user, the communication module will only transmit the radio unit 8 for a certain period B after sending the warning signal. Implement standby.

  When a remote operation is accepted from the center / user during a certain period B (S204: YES, see FIG. 4E), the standby of the wireless unit 8 is further extended for a certain period B from the time of acceptance. If there is no request from the center / user even after the period B has elapsed (S205: YES), the center / user is notified of stopping the wireless unit 8 (FIGS. 4C and 4F). , (H)), the counter C is started, and when there is an extension request from the center / user within a certain period C (S208: YES, see FIG. 4 (g)), the wireless unit is moved to step S203. Extends the standby state of 8. When the counter C ends without an extension request (S209), the wireless unit 8 is stopped after notifying the standby stop (see FIGS. 4C and 4H). To do.

When the fixed period B has elapsed, the center / user is notified of the standby stop (see FIG. 4F).
When an extension request is received from the center / user (S208: YES, see FIG. 4 (g)), the control unit 7 moves to step S203 when specifying the identity by a predetermined authentication method. By starting the counter B, the standby state of the wireless unit 8 is further extended. When the counter C is finished without an extension request, the wireless unit 8 is stopped.
Even after the standby of the wireless unit 8 of the communication module 1 is stopped, the theft monitoring ECU 9 in the vehicle continues to monitor, and when the fraud to the vehicle is detected again, the above-described theft interruption process is executed. .

  In addition, when the communication module 1 cannot notify the center / user outside the service area when notifying the standby stop, the communication module 1 forcibly stops the standby, enters the power saving mode, and prevents the vehicle battery from running out. In this case, if the communication module 1 is out of service area or the like and the notification is not received after a certain period of time A (1 week), B (2 days), C (2 hours), D (2 days), the center 2 The communication module 1 is notified that the standby is stopped.

By the way, in the present embodiment, it is also possible to cope with a malfunction assumed as follows.
When a thief steals a vehicle, the vehicle is stored in a place where communication cannot be performed between the communication module 1 and the base station 11 until the predetermined period A or the predetermined period B elapses, and the communication module 1 stops the standby state. It is conceivable to carry out the vehicle after waiting for this.

  In order to deal with such problems, when the communication module 1 cannot be connected to the base station 11 or the center 2 (including acquisition of a pilot channel or the like), a counter for counting the fixed period A and the fixed period B is set. I decided to stop. Thereby, the connection time with the base station 11 and the center 2 can be ensured reliably, and it can respond to a theft reliably.

  In addition, since the operation of the communication module 1 described above may cause problems if the operation is not stopped, for example, at the time of vehicle inspection or the like, the operation stop request is transmitted from the mobile phone 3 or the like to the communication module 1 and stopped. It is possible to restore the operation. In this case, in addition to transmitting an operation stop request from the mobile phone 3 or the like to the communication module 1 to stop the operation, the center 2 may be notified so that reception of the theft signal may not be accepted.

  According to such an embodiment, the control unit 7 of the communication module 1 stops the radio unit 8 when a fixed period A (one week) has elapsed since the driver got off, and the theft monitoring ECU 9 When the wireless unit 8 is detected to be fraudulent, the standby state is extended for a fixed period B shorter than the fixed period A in the standby state of the wireless unit 8 and is set in the standby state for a fixed period B when the wireless unit 8 is stopped. When the radio unit 8 with high power consumption is not expected to be remotely operated, the battery unit is stopped to prevent the battery from going up, and in the case of theft, the radio unit 8 is allowed to stand by for only a short period of 2 days for remote operation. By making it possible, it is possible to appropriately cope with a situation where a stolen vehicle is transported overseas.

In addition, when the communication module 1 receives an operation request during a predetermined period B, the standby state of the wireless unit 8 is further extended by the predetermined period B, so that the standby of the wireless unit 8 is made according to the user's intention. The state can be effectively extended.
Further, the communication module 1 notifies the user that the wireless unit 8 is stopped when the fixed period A has elapsed, and stops the wireless unit 8 when the user does not make an extension request, and makes an extension request. Sometimes, the standby state of the wireless unit 8 is further extended, so that the standby state of the wireless unit 8 can be more effectively extended according to the user's intention.

(Second embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. 10, and the same steps as those in the first embodiment will be denoted by the same step numbers and description thereof will be omitted. In the first embodiment, when fraud is detected during a certain period A, the standby state for a certain period B is extended after the theft interruption shown in FIG. 3 (see FIG. 4). Since the present invention is characterized in that the fixed period B is set shorter than the fixed period A, for example, an illegal act is detected at an early stage of the fixed period A and the control shifts to the theft interrupt control shown in FIG. In this case, it becomes shorter than extending the standby state of the communication module 1 for the remaining period of the predetermined period A, and the communication module 1 shifts to the power saving mode while tracking the stolen vehicle. There is a risk that it will not be possible to respond to. In addition, if fraudulent activity is detected during a certain period A, if the count for the certain period A is continued as it is, fraudulent activity is detected at a later stage of the certain period A and the control shifts to theft interrupt control shown in FIG. In this case, the remaining time is short, and the communication module 1 may shift to the power saving mode while tracking the stolen vehicle.

In order to deal with such a problem, in this embodiment, the following measures are taken.
FIG. 10 is a flowchart showing the operation of the communication module 1. As shown in FIG. 10, after the driver gets off (S101: YES), it is determined whether the counter A ends (S103) or whether the theft monitoring ECU 9 detects an illegal act on the vehicle (S301). When an illegal act is detected (S301: YES), the remaining time of the counter A is compared with the counter B time (S302). At this time, if the remaining time of the counter A is longer than the time of the counter B (S302: NO), the process of the counter A is continued as it is by moving to step S103. Further, when the remaining time of the counter A is shorter than the time of the counter B (S302: YES), the control is performed after the theft interrupt shown in FIG.

  According to such an embodiment, when an illegal act such as theft occurs during the fixed period A, the count of the fixed period A is continued as it is or extended by the fixed period B according to the timing. The standby state of the communication module 1 can be continued or extended as long as the battery can be prevented from running out, and it is possible to cope with theft.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIG. In FIG. 11 showing the operation of the communication module 1, when an illegal act is detected during a certain period A after the driver gets off (S401: YES), the counter A is reset (S402). . As a result, the counter A starts counting from the beginning, so that the predetermined period A can be extended.
According to such an embodiment, since the standby state of the communication module 1 is extended when an illegal act is detected, it is possible to cope with theft while preventing the battery from running out.

The present invention is not limited to the above embodiment, but can be modified or expanded as follows.
Instead of notifying the user of the possibility of the battery running out of the vehicle, the center 2 may notify the user that the battery may run out on behalf of the vehicle. In this case, the vehicle continues to supply power to the wireless unit 8 for a certain period B when notifying the center that the battery is running.

Notification to the user can be made in real time by sending a predetermined mail to the user's mobile phone (or PC) 3.
The wireless communication network is not limited to a mobile phone network such as PDC, cdma, and w-cdma, and a PHS network, but may be a wireless LAN network or a UWB network.

The request to the communication module 1 is not limited to the center 2 but may be made directly from the user's mobile phone (or PC) 3.
Communication between the operation target ECU 4 and the theft monitoring ECU 9 may be either in-vehicle LAN or one-to-one communication using a direct line.

The power source of the wireless unit 8 of the communication module 1 may be provided outside the communication module 1.
The fixed periods A (one week), B (two days), C (two hours), and D (two days) counted by the control unit 7 can be arbitrarily set as long as B <A is satisfied. Further, the time count of these periods may be implemented by an external ECU and notified to the communication module 1.
The present invention may be applied to an electric vehicle or a hybrid vehicle.
