Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each of the following embodiments, the same or equivalent portions will be denoted by the same reference numerals for description.

(First embodiment)
The first embodiment will be described. FIG. 1 is a schematic diagram showing the overall configuration of the stolen vehicle search device according to the first embodiment. The stolen vehicle search device has a configuration including an on-vehicle device including a TPMS and an external device provided outside the vehicle. First, the TPMS used in the stolen vehicle search device according to the present embodiment will be described.

As shown in FIG. 1, the TPMS is attached to the vehicle 1 and includes a transmitter 2, a receiver 3 and a display 4. In the present embodiment, the case where the transmitter 2 included in the TPMS is a tire-side device will be described as an example, but the transmission included in the tire condition detecting device that detects road surface condition, tire wear, and the like. It may be a machine or the like.

The transmitter 2 is attached to each of the four wheels 5a to 5d of the vehicle 1, detects the air pressure and the temperature inside the tire attached to each of the wheels 5a to 5d, and a detection signal indicating the detection result. Is stored in a frame and transmitted. The receiver 3 is attached to the vehicle body 6 side of the vehicle 1, receives the frame transmitted from the transmitter 2, and performs various processes and calculations based on the detection signal stored therein. That is, the tire pressure is obtained. FIG. 2 is a block diagram showing details of the transmitter 2 and the receiver 3.

As shown in FIG. 2, the transmitter 2 includes a sensing unit 2a, a control unit 2b, an RF transmission unit 2c, a battery 2d, and a transmission antenna 2e.

The sensing unit 2a is configured to include, for example, a pressure sensor and a temperature sensor, and outputs a detection signal according to tire air pressure and a detection signal according to temperature as a detection signal regarding tire air pressure.

The control unit 2b is composed of a well-known microcomputer including a CPU, a ROM, a RAM, an I/O, etc., and executes a predetermined process according to a program stored in the ROM or the like.

Specifically, the control unit 2b receives the detection signal regarding the tire air pressure from the sensing unit 2a, processes the signal as necessary, processes it as necessary, and shows the detection result data (hereinafter, referred to as tire air pressure data). It is stored in the frame to be transmitted as. After that, the controller 2b sends the frame to the RF transmitter 2c. In the frame, in addition to data relating to tire pressure, unique ID information attached to each transmitter 2 is stored, and the frame to be transmitted is that of the own vehicle, and which transmitter 2 has transmitted it. Can be specified. The process of sending a signal to the RF transmission unit 2c is executed at predetermined intervals according to the program, but the control unit 2b transmits the frame to the RF transmission unit to prevent batting between transmission data from the transmitters 2. The timing to send to 2c is controlled.

The RF transmission unit 2c functions as an output unit that transmits the frame transmitted from the control unit 2b to the receiver 3 via the transmission antenna 2e by radio waves in an RF (Radio Frequency) band, for example, a 300 MHz band.

The battery 2d supplies electric power to the control unit 2b and the like, and receives power supply from the battery 2d to collect data on tire air pressure in the sensing unit 2a and various calculations in the control unit 2b. Is executed.

The transmitter 2 configured as described above is attached to, for example, an air injection valve in each of the wheels 5a to 5d, and is arranged so that the sensing unit 2a is exposed inside the tire. As a result, the tire pressure and the temperature inside the tire are detected, and the frame is transmitted at a predetermined cycle (for example, every one minute) through the transmission antenna 2e provided in each transmitter 2.

As described above, the transmitter provided in the tire condition detecting device may be used instead of the transmitter 2 provided in the TPMS as the tire side device. Further, the tire side device may be directly attached to the tire instead of being attached to the wheel.

Further, the receiver 3 is configured to include an antenna 3a, an RF receiver 3b, and a controller 3c.

The antenna 3 a is a vehicle-mounted antenna fixed to the vehicle body 6 that receives the frames sent from the transmitters 2. Here, the antenna 3a is one common antenna that receives the frames transmitted from the transmitters 2 as a whole, but a plurality of antennas may be provided corresponding to the transmitters 2.

When the frame transmitted from each transmitter 2 is received by the antenna 3a, the RF receiving unit 3b functions as an input unit that inputs the frame and sends it to the control unit 3c.

The control unit 3c is configured by a well-known microcomputer including a CPU, a ROM, a RAM, an I/O, etc., and executes a predetermined process according to a program stored in the ROM or the like.

Specifically, the control unit 3c stores the ID information of each transmitter 2 of the vehicle in a storage device such as a RAM. When the control unit 3c receives the frame, the control unit 3c collates the ID information stored in the frame, and if the ID information matches any of the ID information of the transmitters 2 of the vehicle, the control unit 3c stores the frame in the received frame. Various signal processes and calculations are performed based on the data indicating the detection results. As a result, the control unit 3c obtains the tire air pressure and outputs an electric signal corresponding to the obtained tire air pressure to the display unit 4. For example, the control unit 3c compares the obtained tire air pressure with a predetermined threshold Th, and when detecting that the tire air pressure has decreased, outputs a signal to that effect to the display unit 4. As a result, the display 4 is informed that the tire air pressure of any of the four wheels 5a to 5d has dropped.

As shown in FIG. 1, the display device 4 is arranged in a place where the driver can visually recognize, and is configured by a display or the like installed in an instrument panel of the vehicle 1, for example. For example, when a signal indicating that the tire air pressure has dropped is sent from the control unit 3c of the receiver 3, the display unit 4 displays a message to that effect to notify the driver of the tire air pressure drop.

The TPMS is configured by such a structure, and the stolen vehicle search device is configured using the TPMS.

Next, each part which comprises the stolen vehicle search device with the transmitter 2 in TPMS is demonstrated.

In the vehicle 1, the stolen vehicle search device utilizes a plurality of electronic control devices (hereinafter referred to as ECUs) 8 and 9 and an RF receiver 7 in addition to the transmitter 2 as a mechanism for stopping the vehicle 1. There is. As the ECUs 8 and 9, a verification ECU 8, a body control ECU (hereinafter referred to as a body ECU) 9 and the like are used.

Further, the stolen vehicle search device is configured to include a GS communication device 10, a communication device (hereinafter, referred to as police communication device) 12 provided in a police station, etc. as an external device of the vehicle 1.

The verification ECU 8 is, for example, an ECU used for verification of an electronic key in a smart key system. The smart key system is a system that enables a vehicle door to be opened and closed and a vehicle to be started without using a mechanical key by carrying a portable device that constitutes an electronic key called a smart key. The ID information of the portable device is transmitted to the verification ECU 8 by data communication, and the verification ECU 8 verifies whether the previously stored verification ID information matches the ID information of the portable device. A control signal for opening and closing the door and starting the vehicle is transmitted to the body ECU 9. The smart key system and smart key are registered trademarks.

Further, in the case of the present embodiment, when the verification ECU 8 receives the notification signal sent from the GS communication device 10 through the RF receiver 7 as described later, the ID information included in the notification signal is the ID information for verification. It is determined whether or not

Here, the ID information included in the notification signal is the ID information of the transmitter 2 in the stolen vehicle (hereinafter, also referred to as transmitter ID) or the ID information for verification of the smart key system (hereinafter, referred to as verification ID). There is. Further, the verification ECU 8 stores verification ID information, and can also acquire the ID information of the transmitter 2 from the receiver 3 of the TPMS. Therefore, the verification ECU 8 verifies the transmitter ID or the verification ID included in the notification signal with the verification ID information stored in the verification ECU 8 or the ID information of the transmitter 2 acquired from the receiver 3. it can. Then, the case where they match with each other here means that the vehicle 1 is a stolen vehicle.

Therefore, if the collation results here are in agreement, the collation ECU 8 outputs a control signal to that effect to the body ECU 9, thereby opening/closing the door of the vehicle 1 or starting the vehicle. Prohibition notices that prevent the Alternatively, if the collation result here is the same, the collation ECU 8 opens or closes the door or starts the vehicle even if it collates that the ID information of the portable device matches the ID information for collation. The control signal for enabling the above is not transmitted to the body ECU 9.

The body ECU 9 performs various vehicle controls. When a control signal indicating a verification result is sent from the verification ECU 8, the body ECU 9 executes controls for opening and closing the door and starting the vehicle. Specifically, when a control signal indicating that the verification ID information and the ID information of the portable device match each other is transmitted from the verification ECU 8, the body ECU 9 enables the opening and closing of the door and the start of the vehicle. Or Based on this, for example, when the user touches a switch of a door knob (not shown), the door can be opened and closed, and when a push start switch (not shown) is pressed, the engine can be started.

Further, when the body ECU 9 does not receive a control signal from the verification ECU 8 indicating that the ID information for verification and the ID information of the portable device match, or if a prohibition notification arrives, the body ECU 9 detects that the door of the vehicle 1 is closed. Do not allow opening/closing or vehicle activation.

Although the body ECU 9 controls to open and close the door and to start the vehicle, other ECUs such as the door ECU and the engine ECU may be used instead of the body ECU 9. A control signal may be transmitted from the body ECU 9 to the ECU.

The RF receiver 7 plays a role of receiving a notification signal from the GS communication device 10 and transmitting the notification signal to the verification ECU 8 as described later. For the RF receiver 7, for example, a receiver that communicates with a portable device in a smart key system can be shared.

The GS communication device 10 corresponds to an external communication device, is provided as a GS facility, and is installed, for example, inside a refueling machine. The GS communication device 10 receives a frame transmitted from each transmitter 2 included in the vehicle 1 and transmits the frame to the server 11, and when the vehicle 1 is a stolen vehicle, the vehicle 1 is stolen. It plays a role of transmitting a notification signal indicating that the vehicle is a vehicle. Specifically, the GS communication device 10 has a configuration including an RF transceiver 10a and a controller 10b.

The RF transmitting/receiving unit 10a plays a role of receiving a frame transmitted by each transmitter 2 as an RF signal and transmitting a notification signal as an RF signal. The control unit 10b includes a well-known microcomputer including a CPU, a ROM, a RAM, an I/O, and the like, and executes a predetermined process according to a program stored in the ROM or the like. Here, the control unit 10b extracts the ID information of the transmitter 2 from the frame received by the RF transmission/reception unit 10a and sends the ID information to the server 11 together with the GS position information. Further, when the control unit 10b receives a result signal indicating that it is the ID information of a stolen vehicle from the server 11, the control unit 10b performs a process of transmitting a notification signal indicating that the vehicle is a stolen vehicle, or an employee in the GS store. Notify the vehicle that it is a stolen vehicle, and handle the suspension of service.

Although the control unit 10b extracts the ID information of the transmitter 2 from the frame received by the RF transmission/reception unit 10a and sends the ID information to the server 11, at least a portion of the ID information that can identify the vehicle 1 is used. Should be sent.

The server 11 is configured to have a control unit 11a and a database 11b. The control unit 11a includes a well-known microcomputer including a CPU, a ROM, a RAM, an I/O, etc., and executes various processes for searching for a stolen vehicle. The database 11b stores ID information regarding stolen vehicles. The ID information referred to here is a unique transmitter ID given to the transmitter 2 attached to the wheels 5a to 5d of the stolen vehicle, or a collation ID with the unique transmitter ID, for example, an owner who stole the vehicle 1 Is registered in the database 11b by being delivered to the police station. When the collation ID is stored in the server 11, the collation ID is stored in association with the transmitter ID.

With these configurations, when the server 11 receives the ID information and the GS position information from the GS communication device 10, the control unit 11a compares the ID information with the ID information stored in the database 11b. Then, when the control unit 11a obtains the collation result that the ID information matches, the control unit 11a informs the police communication device 12 that a stolen vehicle is found, or the ID information sent to the GS communication device 10 is stolen. It sends a result signal indicating that it belongs to the vehicle.

The police communication device 12 is installed in a police station, a police vehicle, or the like, and when the server 11 reports that a stolen vehicle has been found, plays a role of notifying the police station or the police vehicle. At this time, by also notifying the position information of the GS sent from the GS communication device 10 together with the ID information, it is possible to notify the location of the stolen vehicle. Therefore, it becomes possible for the police officer to seize the stolen vehicle by going to the location where the stolen vehicle was searched.

The stolen vehicle search device according to the present embodiment is configured as described above. Next, the operation of the stolen vehicle search device thus configured will be described in chronological order with reference to FIGS. 3 is a flowchart showing the operation on the vehicle side, FIG. 4 is a flowchart of processing executed by the control unit 10b of the GS communication device 10, and FIG. 5 is a flowchart of processing executed by the control unit 11a of the server 11. It is a flowchart. It should be noted that FIG. 3 collectively describes the processing executed by each unit provided in the vehicle 1. Not all the processes shown in FIG. 3 are executed by a single ECU, but there are processes executed by the transmitter 2, processes executed by individual ECUs, and processes executed by a plurality of ECUs in cooperation.

First, in the vehicle 1, the transmitter 2 executes the process shown in step S100 of FIG. Specifically, the transmitter 2 transmits a frame in which data relating to tire pressure is stored every predetermined period. This frame contains unique ID information of the transmitter 2.

Further, in the GS communication device 10, the control unit 10b receives the frame transmitted from the transmitter 2 as shown in step S200 of FIG. When the frame is received, the process proceeds to step S210, the ID information is extracted from the received frame, and the process of transmitting the ID information and the GS position information to the server 11 is performed.

On the other hand, in the server 11, as shown in step S300 of FIG. 5, after the control unit 11a receives the ID information and the position information transmitted from the GS communication device 10, the process proceeds to step S310 and collation is performed. That is, the ID information of the transmitter 2 of the stolen vehicle stored in the database 11b is compared with the ID information transmitted from the GS communication device 10. Then, the result signal indicating the matching result is returned to the GS communication device 10. For example, when the control unit 11a obtains the collation result that the ID information matches, the control unit 11a notifies the GS communication device 10 of a result signal indicating that the ID information sent is for the stolen vehicle. Further, the server 11 proceeds to step S320 to determine whether or not the collation result indicates that the vehicle is a stolen vehicle. If an affirmative determination is made, the server 11 proceeds to step S330 to find the stolen vehicle in the police communication device 12. I'm trying to tell you where things and stolen vehicles were searched. If a negative determination is made in step S330, the process ends as it is because the vehicle is a general vehicle that is not a stolen vehicle.

Further, in the GS communication device 10, when the result signal is transmitted from the server 11, the control unit 10b receives the result signal in step S220, and then, in step S230, the control unit 10b verifies that the result signal is a stolen vehicle. It is determined whether or not it is shown. Then, if an affirmative determination is made here, the control unit 10b transmits a notification signal indicating that the vehicle is a stolen vehicle to the vehicle 1 through the RF transmission/reception unit 10a in step S240, or in the store of the GS in step S250. Notify employees of stolen vehicles. At this time, when transmitting the notification signal to the vehicle 1, the transmitter ID sent by the vehicle 1 or the verification associated with the transmitter ID is transmitted so that the vehicle 1 can verify that the notification signal is for itself. The ID is included in the notification signal. Further, the control unit 10b proceeds to step S260 and stops the service to the vehicle 1, which is the stolen vehicle, specifically, stops the fuel supply service so that the fuel supply is not performed.

Further, in vehicle 1, in step S110, when RF receiver 7 receives the notification signal transmitted from GS communication device 10, in step S120, verification ECU 8 performs verification with the ID information included in the notification signal. I do. That is, the verification ECU 8 matches the transmitter ID or the verification ID included in the notification signal with the verification ID information stored in the verification ECU 8 or the ID information of the transmitter 2 acquired from the receiver 3. Check whether or not. If they match, the verification ECU 8 performs a key invalidation registration process. Specifically, the verification ECU 8 sends a prohibition notification to the body ECU 9 so that the door of the vehicle 1 cannot be opened or closed and the vehicle cannot be started. Alternatively, the verification ECU 8 does not transmit to the body ECU 9 a control signal that enables the opening and closing of the door or the vehicle start even if it is verified that the ID information of the portable device matches the ID information for verification. As a result, as shown in step S130, after the start of the vehicle is stopped, that is, after the engine is stopped, the vehicle cannot be restarted again, and the stolen vehicle can be prevented from escaping.

In the GS, refueling is to be performed while the vehicle 1 is in a stopped state, that is, the engine is stopped. Therefore, typically, in step S130, the vehicle cannot be started again, and the stolen vehicle is prevented from escaping. Further, when the vehicle 1 is in the stopped state, the power supply from the battery is normally stopped, but the verification of the ID information by the verification ECU 8 is periodically executed. Therefore, the operation of the flowchart shown in FIG. 3 is executed even when the vehicle 1 is stopped.

As described above, in the stolen vehicle search device of this embodiment, the GS communication device 10 receives the frame including the ID information transmitted from the transmitter 2 of the TPMS provided in the vehicle 1. Further, based on the collation between the ID information received by the GS communication device 10 and the ID information about the stolen vehicle stored in the server 11, the stolen vehicle is identified. When the vehicle is identified as a stolen vehicle, the GS communication device 10 transmits a notification signal to the vehicle 1 so that the vehicle cannot be started again after the engine is stopped.

As a result, the stolen vehicle that was trying to refuel with GS cannot start the vehicle again, and it becomes possible to prevent the stolen vehicle from escaping. Therefore, the stolen vehicle can be suppressed more efficiently. In particular, if the vehicle is identified as a stolen vehicle, the server 11 informs the police communication device 12 that the stolen vehicle has been found, and informs the stolen vehicle and its location in the police station or in the police vehicle. ing. Therefore, the stolen vehicle can be more efficiently captured.

Further, in the present embodiment, when the vehicle is identified as a stolen vehicle, the GS communication device 10 stops providing the service to the vehicle 1. Therefore, even if the stolen vehicle refuels while the engine is running and then escapes, it is possible to limit the escapeable distance to the remaining fuel amount.

(Second embodiment)
The second embodiment will be described. The present embodiment is an addition of a coping method when refueling is performed with the vehicle being started up to the first embodiment, and other aspects are similar to the first embodiment, so the first embodiment Only the parts that differ from

In the present embodiment, as shown in FIG. 6, the vehicle 1 is provided with an ECU (hereinafter referred to as a navigation ECU) 13 for navigation control, and based on information from the navigation ECU 13, the vehicle 1 is stopped. Is being done.

The navigation ECU 13 has a database of map information and measures the current position of the vehicle 1 based on GPS signals transmitted from GPS (Global Positioning System) satellites so that the current position of the vehicle 1 can be grasped. Has become. Based on the current position information indicated by the navigation ECU 13, if the vehicle 1 is currently on a public road and the vehicle 1 stops, it is a place that affects the surroundings, or the vehicle 1 stops like a parking lot. Even so, it is possible to know if it is a place that does not affect the surroundings.

Based on this current position information, in the present embodiment, in the vehicle 1, the operation of the flowchart shown in FIG. 7 is performed instead of FIG. 3 described in the first embodiment.

First, in step S400 of FIG. 7, as in step S100 of FIG. 3, when the transmitter 2 transmits a frame in which data regarding tire air pressure is stored for each predetermined transmission cycle, the GS communication device 10 and the server 11 perform the frame transmission of FIG. Each process shown in FIG. 5 is executed. Then, in step S240 of FIG. 4, the GS communication device 10 transmits a notification signal indicating that the vehicle is a stolen vehicle to the vehicle 1 through the RF transceiver 10a.

Based on this, when the RF receiver 7 receives the notification signal transmitted from the GS communication device 10 in step S410 of FIG. 7 as in step S110 of FIG. 3, the processes of step S420 and subsequent steps are executed.

First, in step S420, it is determined whether the vehicle 1 is stopped, that is, whether the engine is stopped. This determination is performed by the verification ECU 8 acquiring information about whether the vehicle 1 is stopped or started from the body ECU 9 or an engine ECU (not shown).

If an affirmative determination is made here, in steps S430 and S440, the same processing as steps S120 and S130 of FIG. 3 is performed. Then, when a negative determination is made in step S420, the process proceeds to step S450.

In step S450, the verification ECU 8 determines whether or not the current position of the vehicle 1 is on a public road, based on the current position information obtained from the navigation ECU 13. Then, if an affirmative determination is made here, the process returns to the process of step S420, and if a negative determination is made, the process proceeds to step S460, and the verification ECU 8 sends a control signal instructing to stop the vehicle 1, that is, the engine, to the body ECU 9. Send to. As a result, the stolen vehicle 1 is forcibly stopped, and the stolen vehicle is prevented from escaping.

Here, in step S450, it is determined whether the current position of the vehicle 1 is on a public road. This is to determine whether or not the environment is one that affects the surroundings when the vehicle 1 is forcibly stopped. When the vehicle 1 is a stolen vehicle, it is not desirable to stop the vehicle 1 if the stopped position is a place that causes trouble to the surroundings while it is desired to stop the vehicle 1 in order to prevent escape. Therefore, the verification ECU 8 forcibly stops the vehicle 1 when the vehicle 1 is located on a public road where the influence on the surroundings is considered to be small.

Note that, here, each processing after step S420 is executed by the verification ECU 8, but it may be executed by any ECU such as the body ECU 9 or the navigation ECU 13.

In this way, the operation of the vehicle 1 of this embodiment is performed. In this way, even if the vehicle 1 is refueling in the GS in the activated state, it is possible to stop the vehicle 1 at a place where even if the vehicle 1 is stopped, the surroundings are less affected. For example, if the vehicle 1 is being refueled, it is considered that the influence on the surroundings is small, not on the public road. Therefore, the verification ECU 8 can forcibly stop the vehicle 1. This makes it possible to prevent the stolen vehicle from escaping.

As described above, even if the stolen vehicle refuels with GS in a state where the stolen vehicle is started without stopping, it is considered that there is little influence on the surroundings during or after refueling. It is possible to forcibly stop the vehicle 1 at a designated location. This enables the stolen vehicle to be more effectively captured.

(Other embodiments)
The present invention is not limited to the above-described embodiments, but can be appropriately modified within the scope described in the claims.

In the above-described embodiment, the vehicle 1 is described as an example of a vehicle that runs on gasoline or the like as a fuel, but the vehicle does not necessarily need the fuel. For example, the present invention can be applied to an electric vehicle and the like. In that case, it is possible to incorporate the GS communication device 10 into a charger or the like.

Further, in the above-described embodiment, the GS communication device 10 provided in the GS can communicate with the vehicle 1 and the server 11 to search for a stolen vehicle. However, the present invention is not limited to the GS communication device 10. The communication device may be provided in another road system. For example, it is conceivable to equip a charger for an electric vehicle provided in a service area with a communication device. Further, as in the second embodiment, when it is determined that the vehicle 1 that is not stopped is a stolen vehicle, the vehicle 1 is stopped. Various road systems include communication devices. Things are possible. For example, it is conceivable to provide a communication device at the entrance of a highway, and in that case, when the vehicle 1 enters a service area or the like, it becomes possible to stop the vehicle 1 in a parking lot.

Further, in the above-described embodiment, the information about the stolen vehicle is stored in the server 11 as the vehicle to be searched. However, not only the stolen vehicle but also information about the escape vehicle of the criminal and information about the vehicle of the person with dementia can be stored in the server 11 and used for searching for those vehicles. That is, the present invention is applicable not only to the stolen vehicle search device but also to a vehicle search device that searches for a vehicle to be searched.

For stolen vehicles and vehicles for people with dementia, the owner of the stolen vehicle 1 or a person inside the demented person can report to the police station about the ID information of the transmitter 2 in the database 11b. However, it is assumed that criminal escape vehicles have not been registered in advance. However, the escape vehicle owned by the criminal may be known at the police station, and in that case, the ID information of the transmitter 2 attached to the wheel of the escape vehicle at the police station is registered in the database 11b. Just do it. In addition, for example, when attaching a license plate to the vehicle 1 at an automobile inspection site or the like, the ID information of the transmitter 2 may also be acquired and a database in which the license plate and the ID information are associated may be created. Conceivable. By doing this, the ID information of the transmitter 2 of the escape vehicle can be read from the database by identifying the police vehicle following the vehicle in flight or by identifying the image from the image acquired by the road system and inputting the number. Therefore, it may be registered in the database 11b.

Further, in the above-described embodiment, the case where each of the wheels 5a to 5d provided with a tire is provided with the transmitter 2 that serves as a tire side device has been described as an example. good. For example, the tire pressure is desired to be detected for each of the wheels 5a to 5d, but the road surface state detection may be detected by at least one wheel. Similarly, if tire wear can be detected by at least one wheel, it can be estimated for other wheels. Therefore, it is sufficient that at least one of the wheels 5a to 5d is equipped with the tire side device.

Further, in the above embodiment, the case where the TPMS receiver 3 and the RF receiver 7 in the smart key system are separately configured has been described, but they may be configured by one common receiver.
