  The present invention performs communication between an in-vehicle device mounted on a vehicle and a center, and a vehicle detection system configured to transmit vehicle information to the center by the in-vehicle device, and the in-vehicle device used in the vehicle detection system And about the center.

  There is a system in which various management is performed by providing vehicle information and travel information from an in-vehicle device mounted on a vehicle to a center side. For example, in Patent Document 1, the position information of the vehicle is sequentially transmitted from the vehicle side by communication, and the position information received from the vehicle side enters a pre-stored specific area on the center side. In this system, it is determined whether or not the vehicle is approaching, and if the vehicle is approaching, a warning is notified to the vehicle. In addition, the system is configured to be able to provide information to PCs such as general citizens through the Internet line.

JP 2004-206510 A

  However, in the above, the vehicle position information is sequentially transmitted to the center using the quasi-zenith satellite. In this case, communication with the center is frequently performed, so the communication amount is large and communication is performed. There is a problem that costs increase. For example, when this system is applied to control or vehicle information collection, if the vehicle traveling on the road sequentially transmits position information, the amount of information becomes enormous and the communication cost becomes large. It is not suitable for practical use in terms of burden of communication charges.

  The present invention has been made in consideration of the above-mentioned circumstances, and its object is to detect a vehicle at a low cost and to perform reliable communication while minimizing the amount of communication with the center. Another object of the present invention is to provide an in-vehicle device and a center used in the vehicle detection system.

  In the first aspect of the invention, the in-vehicle device stores the vehicle information in the information storage means and travels the data indicating the running state represented by the speed or driving operation at the own vehicle position detected by the own vehicle position recognition means. It is memorized as information, and the designated area entry judging means judges whether or not the position of the own vehicle recognized by the own vehicle position recognizing means has entered the designated area stored in the designated area storing means. . When the on-board device determines that the designated area entry determining means has entered the designated area, the on-vehicle apparatus storage information transmitting means transmits the vehicle information and the travel information stored in the information storage means to the center. On the other hand, in the center, when the receiving means receives the information transmitted from the vehicle-mounted device, the received information storage means stores the received vehicle information and travel information, and the vehicle detection means stores the stored travel information. And the vehicle provided with the vehicle equipment which transmitted predetermined information based on vehicle information is detected.

  As a result, in the in-vehicle device, the travel information is stored by sequentially storing the information in the vehicle information storage means, and the travel information and the vehicle information stored in the information storage means when it is determined that the vehicle has entered the designated area. By transmitting, necessary information can be reliably transmitted in a timely manner, and the cost required for communication can be reduced. In the center, the vehicle information and travel information of the vehicle that has entered the designated area can be obtained with certainty, so the necessary information was reliably obtained and the target information was transmitted while reducing the amount of information received. A vehicle can be detected.

  In addition, the center can obtain information indicating the vehicle's driving status at the timing of entry into the designated area, so it can detect and respond to vehicles that are expected to violate in advance. In the task of collecting travel information of various vehicles, it is possible to collect useful data without increasing communication such as sequential transmission to the in-vehicle device.

And since the vehicle information of the detected vehicle can be transmitted to the mobile terminal and displayed on the display device by the vehicle information transmitting means to the center, the vehicle detected at the place where the owner of the mobile terminal is located can be displayed. The vehicle information can be viewed, and the vehicle information can be confirmed by looking at the display device of the portable terminal at a site such as a crackdown, and a reliable crackdown operation can be performed.
Furthermore, when the on-vehicle device determines that the vehicle position has entered the designated area by the designated area entry judging means, the on-vehicle device has a load capacity of the information storage means when the vehicle traveling speed exceeds the speed limit. Since it is stored as travel information when it exceeds or when it falls under at least one of the cases where the continuous operation time is longer than the specified time, so-called violation is determined only when entering the designated area. Can be stored in the case of committing the information, and accurate information can be transmitted while significantly reducing the amount of information stored in the information storage means.
In addition, the vehicle which is the target of the travel information transmitted from the center and stored in the information storage means of the mobile terminal is measured by the vehicle measuring device disposed in the vicinity of the mobile terminal, and the travel stored in the mobile terminal When it becomes the driving information to be memorized with the same content as the information, it is provided with a determination means for determining the vehicle as a violating vehicle. It can be narrowed down and set, and if it becomes traveling information that shows the same violation even in the measurement using the measuring device in the vicinity of the mobile terminal, it can be arrested as a violation vehicle, so randomly It is possible to carry out a control work focused on vehicles for which violations are predicted compared to the case of measuring travel information of passing vehicles.

In the second aspect of the invention, in the first aspect of the invention, in the first aspect of the invention, the designated area setting means for setting the designated area at the center and the setting information transmission for sending the information on the designated area set by the designated area setting means to the vehicle-mounted device When the information on the designated area is received from the setting information transmitting means on the in-vehicle device, the received information on the designated area is stored in the designated area storage means. The designated area can be newly set or changed at once by sending to the side.

According to the invention of claim 3, in the invention of claim 2 , the specified information receiving means is provided in the center so that the information of the specified area can be received from the portable terminal. When the information on the designated area is received, the received information on the designated area is set, so that the owner of the mobile terminal can newly set or update the designated area. The machine can be set by sending information of the designated area. For example, there is a police officer who owns a mobile terminal at the enforcement site, and by setting the road subject to enforcement as a designated area, the vehicle subject to enforcement is predicted before reaching the position where the portable terminal exists. This can be recognized in advance.

According to the invention of claim 4, in the invention of claims 1 to 3 , the designated area set by the designated area setting means is on a road that is a predetermined distance away from the location of the mobile terminal and is located at the location of the mobile terminal. Because it can be set in the area on the lane side of the road, the police officer who owns the mobile terminal can easily and quickly obtain the driving information of the vehicle that reaches the road on the spot when carrying out crackdowns, etc. In this way, it is possible to efficiently control the vehicle after specifying the target vehicle in advance.

According to the invention of claim 5, in the inventions of claims 1 to 4 , as the designated area set by the designated area setting means, a predetermined area including the location of the portable terminal can be set. By setting a predetermined range centered on the position where the owner is, it is possible to obtain information on vehicles entering the area and narrow down target vehicles quickly and reliably.

According to the invention of claim 6, in the invention of claims 1 to 5 , the vehicle-mounted device is provided with communication means for communicating with the portable terminal, and enters the communication area of the portable terminal and communicates from the portable terminal side. When the request signal is received, the travel information stored in the information storage means is transmitted to the mobile terminal, so that detailed information on the vehicle determined as the specific vehicle on the center side is directly mounted on the mobile terminal side. You can get by accessing the machine.

According to the invention of claim 7, in the invention of claim 6 , the communication with the portable terminal by the communication means of the in-vehicle device can be carried out by the short-range wireless system, and it is non-contact and moves. Communication is also possible, and vehicle travel information can be obtained quickly and easily.

According to the invention of claim 8, in the invention of claims 1 to 7, when the in- vehicle device is provided with the notification means and the specified region entry determining means determines that the vehicle has entered the specified region, the in-vehicle device storage information is transmitted. Since the means transmits the vehicle information and travel information stored in the information storage means to the center and informs the user of the vehicle that the information is transmitted to the center by the notification means, the in-vehicle device is installed. The driver or passenger of the vehicle that has been confirmed can recognize that the vehicle has entered the designated area and can recognize the traveling information at that time. It is possible to take measures such as revising driving so as not to violate the vehicle. In addition, even if the driving information or vehicle information is transmitted from the center side to the mobile terminal, it is possible to take measures such as changing to a state where no violation has occurred before passing the site where the mobile terminal exists. As a result, since the information can be recognized in advance, the driver can be conscious of driving safely.

According to a ninth aspect of the present invention, in the first to eighth aspects of the present invention, the information received from the license plate image of the vehicle photographed by the imaging device from the portable terminal by the center is received by the receiving means, and the received information Since the vehicle information / running information of the corresponding vehicle stored in the storage means is configured to be transmitted to the portable terminal by the vehicle information transmitting means, the person who owns the portable terminal at the site is the number of the target vehicle By photographing the plate with the imaging device, vehicle information and traveling information of the vehicle can be easily obtained, and vehicle information can be obtained quickly and accurately.

In the invention of claim 10 , the vehicle detection system according to any one of claims 1 to 9 can be used with excellent usability with reduced communication costs.

In the eleventh aspect of the invention, in the vehicle detection system according to any one of the first to ninth aspects, the amount of communication can be reduced and the cost can be reduced while acquiring necessary information from the in- vehicle device side. Can be used.

Here, the traveling information includes speed history, position information, vehicle information, loading information, driver state information, and the like. The in-vehicle device 2 performs short-range wireless communication with the mobile terminal 3 and transmits similar traveling information. The center 1 communicates with the mobile terminal 3 to transmit necessary vehicle information to the mobile terminal 3 side. Examples of the vehicle information include vehicle identification information and violation information.

Next, the operation of the present embodiment will be described with reference to FIGS.
First, the operation when the designated area S is set in advance will be described. First, the vehicle-mounted device 2 starts executing the main routine when the power is turned on, and operates according to the flowchart shown in FIG. When the IG key (start key) is turned on to start operation (A1), the vehicle position is then detected (A2). The vehicle position is calculated by receiving signals from a plurality of GPS signals by the GPS receiver 10a of the vehicle position detector 10. Next, it compares with the position information of the designated area memorize | stored in the memory | storage part 8 (A3), and it is judged whether it entered into the new designated area S (A4). If it is determined that the vehicle has entered the new designated area S (YES in A4), the travel information stored in the storage unit 8 is read and transmitted to the center 1 (A5). Thereafter, when the operation is not completed (when the IG key is not turned off) (NO in A6), the process proceeds to A2. Similarly, if NO is determined in A4, the process proceeds to A2 via A6. When the operation is finished (YES in A6), the program is finished.

  As a result, the vehicle information and travel information stored in the storage unit 8 in the vehicle 4 can be transmitted to the center 1 at the timing when the vehicle 4 enters the new designated area S. In the main routine of this vehicle-mounted device, the vehicle-mounted device 2 determines whether or not the vehicle has entered a new designated area S in step A4, and once enters the designated area S and travel information is sent to the center 1. After the transmission, the traveling information is not transmitted even during the period existing in the designated area S. Further, even when the vehicle enters again the same designated area S, it is not regarded as a new entry. That is, this is a method in which traveling information is transmitted once to the same designated area S when entering. However, even when entering the same designated region S, a condition for determining that the vehicle has entered the new designated region S can be attached if the time difference from the previous entry is large.

  While executing the main routine described above, the in-vehicle device 2 executes the programs of the flowcharts shown in FIGS. 6 and 7 at an appropriate timing when the IG key is turned on. First, in the flowchart shown in FIG. 6, the in-vehicle device 2 registers data in the designated area S as data to be compared with the current position during the execution of the main routine. The setting of the designated area S is received by communication from the information center 1 side, and the in-vehicle device 2 stores the received information on the designated area in the storage unit 8 when receiving the information (YES in B1). In this case, in addition to the information stored and registered in advance on the in-vehicle device 2 side, the information on the designated area S received from the outside is stored. Further, in the case of the designated area S in which a term with a time limit is set, the expired designated area information is discarded, and new designated area information is registered and updated.

  Next, in the flowchart shown in FIG. 7, the in-vehicle device 2 detects and stores data of travel information transmitted to the information center 1 in A5 of the main routine. First, the vehicle-mounted device 2 starts executing this routine (running information storage routine) in a state where the power is turned on. When the IG key is turned on and the operation is started (C1), the load amount is detected next ( C2). Here, in order to estimate the loading amount of the vehicle during traveling, the signal of the acceleration sensor 10b or the signal of the suspension sensor 15b is input, and the input signal is calculated by a predetermined algorithm, The load amount can be estimated by estimating the weight of the vehicle 4.

  In addition to the above-described driving information, the imaging device 9 can be used to photograph the driver's face and upper body movements, or to measure the response to the question asked by voice, and to determine the behavior and brake / accelerator operation and steering wheel Judging whether the driving behavior is normal or not in relation to the operation, etc., also record the driving information such as whether the driver's behavior exhibits symptoms of negligent driving such as drowsy driving or drunk driving Can do.

  Next, the vehicle-mounted device 2 detects the speed of the host vehicle from the detection data of the vehicle speed sensor 15a or the movement amount of the host vehicle position (C3), and then detects the continuous operation time from the start of driving (C4). The in-vehicle device 2 stores the estimated load amount, own vehicle speed, and driving time information obtained in Steps C2 to C4 in the storage unit 8 as driving information (C5), and if driving has not ended (in C6) NO) Returning to Step C2 again, and continuing the process of storing the travel information of the host vehicle in the storage unit 8 every time an appropriate time interval or travel distance elapses, the travel information is sequentially stored according to the travel of the vehicle. To go.

  Next, the main routine of the center 1 will be described according to the flowchart shown in FIG. The center 1 repeatedly executes the main routine at an appropriate timing by the control device 17 and waits to receive travel information from the in-vehicle device 2 when the execution is started (D1). As described above, when the in-vehicle device 2 enters the designated region S and transmission processing is performed in A5 of the main routine, the control device 17 receives the travel information via the communication device 18 (YES in D1). The received travel information is stored in the storage unit 19.

  Subsequently, the control device 17 determines, based on the received travel information, whether or not the vehicle is in violation such as exceeding the load capacity or exceeding the speed limit on the road. (D3). In the center 1, it is possible to determine whether there is a violation by checking the traveling information and vehicle information of the target vehicle 4, the speed limit in the designated area S, and various traffic compliance conditions. If the vehicle that has received the travel information is not a violation vehicle (NO in D4), the control device 17 returns to step D1 and waits for reception of the travel information. The vehicle information serving as information for identifying the vehicle and the vehicle recognition information indicating the violation content are transmitted by the communication device 18 (D5). The object to be transmitted is the portable terminal 3 possessed by the police officer P or the like who is carrying out the control.

  As a result, when the vehicle 4 enters a new designated area S, traveling information detected before or before the vehicle 4 enters the designated area S is transmitted, and the traveling information received at that time is a violation. It is possible to determine whether or not the vehicle 4 is in violation at that time, and it is determined in advance that there is a high possibility that the vehicle 4 is in violation even when passing through the position of the mobile terminal 3. It can be done.

  When the vehicle recognition information is transmitted from the center 1, the portable terminal 3 executes the flowchart of the main routine shown in FIG. When the control device 22 of the mobile terminal 3 determines whether or not the vehicle recognition information is received from the center 1 and the vehicle recognition information transmitted from the communication device 18 of the center 1 is received by the communication device 23 of the mobile terminal 3 (E1), the received vehicle recognition information and violation information are displayed on the display device 27 (E2).

Next, the setting of the designated area S will be described. In this embodiment, the procedure for setting the designated area S and the type of area can be set corresponding to the following purposes.
First, as the subject for setting the designated area S,
(1) A method of setting in the center 1 and transmitting to the related vehicle-mounted device 2 (2) A method of setting in the portable terminal 3 possessed by the policeman P and transmitting to each vehicle-mounted device 2 via the center 1 Two ways are prepared.

As the size (scale, shape) of the designated area S,
(3) A method in which the designated region S is set at a passing point (narrow region) on the road R. (4) A method in which the designated region S is set in a predetermined range centered on a specific position such as an intersection. In the method 3), for example, on the road that is a predetermined distance away from the position where the policeman P exists, the lane on the side that reaches the position of the policeman P after the vehicle 4 passes the point is set as the designated area S. . As a result, it is possible to carry out enforcement that is restricted to a vehicle that is in a specific running state with a vehicle that passes the position of the policeman P.

  In the method (4), the designated area S is set in a wide range centering on the intersection of the policeman P carrying the mobile terminal 3 or the position of a specific facility, and thus the intersection or the specific facility is directed. The vehicle 4 that travels in this manner is the target of control.

  Next, of the above-described setting of the designated area S, the procedure for setting the designated area S in the center 1 or the terminal device 3 shown in (1) and (2) will be described with reference to FIGS. To explain. First, when setting the designated area S in the center 1, as shown in FIG. 10, when the setting work is performed using the operation switch 21 according to the setting screen displayed on the display device 20 in the center 1, the control device 17 receives the setting input and performs setting processing (F1), and stores the designated area S in the storage unit 19 (F2). Thereafter, the control device 17 of the center 1 transmits information on the designated area to the in-vehicle device 2 by the communication device 18 (F3). On the other hand, in the in-vehicle device 2, as described above, the information on the designated area S is received and set according to the flowchart shown in FIG.

  Next, when the designated area S is set on the portable terminal 3, when the setting operation is performed using the operation switch 28 according to the setting screen displayed on the display device 27 on the portable terminal 3, as shown in FIG. The control device 22 receives the setting input (G1), and transmits the designated area information to the center 1 through the communication device 23 (G2). On the other hand, in the center 1, as shown in the flowchart of FIG. 11, when the control device 17 receives the designated area information through the communication device 18 (F10), the following reception is performed as shown in FIG. The designated area is set (F1), and the designated area S is stored in the storage unit 19 (F2). Similarly, the control device 17 of the center 1 transmits information on the designated area S to the in-vehicle device 2 by the communication device 18 (F3). On the other hand, in the in-vehicle device 2, as described above, the information on the designated area S is received and set according to the flowchart shown in FIG.

  Next, of the above-described setting of the designated area S, a specific method for setting the range of the designated area S shown in (3) and (4) will be described with reference to FIGS. The designated area S is an area where it is effective to set the area to be able to efficiently carry out the enforcement work, for example, when the police conducts a police enforcement system for traffic violations, etc. It is equivalent to an area for collecting various types of data according to the area and collecting it for use in research.

  In the example shown in FIG. 13 corresponding to the method (3), the control is performed on the road R having few branches, and the position where the control is performed is defined as the point where the police officer P is located. This is a case where, for example, a point of about 1 km before the vehicle travels is set as the designated region S1. In this case, a narrow area on the road R is set as the designated area S1, and it is intended to detect that the vehicle 4 equipped with the vehicle-mounted device 2 passes through the area including the point. When setting the designated area S1, as described above, the policeman P at the site can set from the mobile terminal 3 side or can be set in the center 1.

  In the enforcement of the control, it is determined in advance whether or not the vehicle 4 passing through the designated area S1 is a violation vehicle in the center 1 based on vehicle information or travel information transmitted from the in-vehicle device 2 to the center 1 This is for transmitting vehicle information to the portable terminal 3. Actually, at the point where the policeman P is located, a measuring device for cracking down is arranged, and when the target vehicle comes close, it is measured by the measuring device, and it can be determined whether or not the violation is actually made. . As the content of the control, what can be determined by the running state such as speed violation, overloading, drunk driving, dozing driving, and other control are assumed.

  At this time, since the control work narrowed down to the vehicle 4 that has received the travel information and vehicle information as the target vehicle in advance can be performed, the setting and work can be performed easily and quickly, and can be efficiently performed. And if it is determined that the subject vehicle is narrowed when the driving state is actually measured for the narrowed down target vehicle that is expected to be violated, it can be arrested as the current offender. Further, by narrowing down to vehicles that are expected to violate in this way, it is possible to carry out efficient control work without impeding traveling in a normal traveling state.

  If it is not a condition to be cleared by the current offender, even if no violation can be found by measurement by the measuring device, the clearance is based on the violation information in the designated area S transmitted from the vehicle-mounted device 2 of the vehicle 4. You can also

  Next, in the example shown in FIG. 14 corresponding to the method (4), there is a policeman P who owns the mobile terminal 3 at an intersection O where two roads R1 and R2 intersect, and enters this intersection O. This is suitable for the case where the control is performed on the incoming vehicle 4. In this case, the designated area S2 is set within a predetermined radius with the intersection O as the center, for example. Thereby, it is possible to detect the vehicle 4 traveling on either of the roads R1 and R2 entering the designated area S2 and receive the travel information and the vehicle information.

  As the setting of the designated region S2, in addition to the method of setting a predetermined radius centered on a certain point, it is also possible to set a region having the same level determined according to roads, topography, or various conditions. It is possible to set a two-dimensionally expanding region with appropriate conditions such as setting the region along which the distance along the line is a certain range.

  Next, referring to FIG. 15 and FIG. 16, when the target vehicle 4 is determined to be a violating vehicle, the mobile terminal 3 at the site receives the traveling information and vehicle information directly from the violating vehicle 4. The procedure for the case will be described. The in-vehicle device 2 executes the program shown in the flowchart of FIG. 15 in preparation for such a case. The in-vehicle device 2 has a function capable of performing communication by short-range wireless communication by various methods such as Bluetooth or narrow-range communication (DSRC) as the communication device 7. And the control apparatus 5 of the vehicle equipment 2 judges whether transmission of the connection request from the portable terminal 3 was received by the communication apparatus 7 (H1), and the connection with the portable terminal 3 is received when the connection request is received. A process is performed and it responds to the vehicle equipment 2 side (H2). Subsequently, the control device 5 reads the travel information requested in response to the connection request from the storage unit 8 and transmits it from the communication device 7 to the mobile terminal 3 (H3).

  As described above, since the function for providing travel information is provided on the in-vehicle device 2 side, when the violation of the vehicle 4 is determined, a request is made to the in-vehicle device 2 side by the portable terminal 3 possessed by the police officer P. be able to. FIG. 16 shows a flowchart of the program. First, the control device 22 of the portable terminal 3 makes a connection request to the target in-vehicle device 2 through the communication device 24 (J1), and waits for a response from the in-vehicle device 2 (J2). When the response from the in-vehicle device 2 is received by the communication device 24 (YES in J2), the control circuit 22 of the portable terminal 3 executes a connection process with the in-vehicle device 2 (J3), and is then transmitted from the in-vehicle device 2. Is received by the communication device 24 (J4). As a result, the mobile terminal 3 can check the travel information of the target vehicle 4 by displaying the received travel information on the display device 27.

It can also be configured so that the three sides can cope with either case.

  Note that the above-described method for setting the designated region S is appropriately selected and set according to the scene and situation. By receiving various types of information as vehicle information and travel information, For example, the vehicle being searched can be detected as the vehicle. It can also be used as a means for collecting various information. Even in such a case, it is possible to collect information necessary for communication only at the time of passing through the designated area, instead of the method of always performing communication.

  In addition, even if you pass within the area designated as the designated area S, past driving information is also transmitted when you enter the designated area S, so you are driving maliciously in areas other than the designated area S. Even if the driver is negligent driving such as snoozing, even in situations where the current offender cannot be cleared, the driver of the target vehicle 4 is cautioned about driving from the history of the driving information, It can help to consider safe driving.

  According to the first embodiment as described above, a new designated region S is used as a timing at which the vehicle 4 side acquires and stores the travel information from the in-vehicle device 2 to the center 1 side. Therefore, it is possible to accurately provide necessary information to the center 1 while reducing the frequency of communication as much as possible.

  The designated area S can be set easily and quickly from either the center 1 or the portable terminal 3, and the designated area S can be made an area narrowed down to a point or a wide range. A user-friendly form can be selected according to the road layout and topography.

  Thereafter, the control device 5 makes an information request through the communication device 6 in order to request the center 1 for information on the vehicle with the recognized number (L3). Then, as described above, since the center 1 side receives an information request from the mobile terminal 3 and transmits violation information including vehicle information, the control device 5 of the mobile terminal 3 passes through the communication device 6. This is received and acquired (L4), and this is stored in the storage unit 8 and displayed on the display device 11 or output through the audio output device 13 as necessary.

  As described above, the police officer P possessing the portable terminal 3 can easily and quickly obtain the vehicle information and violation information of the vehicle 4 simply by photographing the license plate of the violation vehicle at the site. This makes it unnecessary to perform the operation of inputting the control information, and makes it possible to efficiently estimate the control work based on the accurate information obtained by reading and recognition processing.

(Fourth embodiment)
20 to 22 show a fourth embodiment of the present invention. Hereinafter, parts different from the first embodiment will be described. In this embodiment, the in-vehicle device 2 stores only when the travel information is violated, and transmits only the information violated when entering the designated area S to the center 1 side. I have to.

  First, in the in-vehicle device 2, the control device 5 executes processing according to the flowchart of the main routine shown in FIG. The flowchart shown in FIG. 20 is obtained by changing a part of FIG. 5 which is a flowchart of the main routine of the in-vehicle device 2 in the first embodiment. That is, the control device 5 determines whether or not it has entered the designated area S in the same manner as described above (A1 to A4, A6), and if it is determined that it has entered the new designated area S (in A4) YES), it is determined whether or not there is violation information among the travel information stored in the storage unit 8 (A20).

  When violation information is not memorize | stored, the control apparatus 5 returns to the process which judges the approach to a designated area again through step A6. If the violation information exists (YES in A20), the control device 5 reads the violation information from the storage unit 8 and transmits it to the center 1 through the communication device 6 (A21). At this time, the control device 5 notifies the display device 11 of the content of the violation information transmitted to the center 1 (A22). Note that the notification operation is not limited to being displayed on the display device 11, but can also be output to the voice output device 13 by voice to notify the driver. One of these notification operations may be performed, or both may be performed.

  Next, with reference to FIG. 21, a procedure for storing violation information from the travel information detected by the in-vehicle device 2 will be described. The processing of the violation information storage routine shown in FIG. 21 is obtained by changing a part of FIG. 7 which is a flowchart of the travel information storage routine of the in-vehicle device 2 in the first embodiment. That is, after acquiring the travel information in the same manner as described above, the control device 5 determines whether or not the acquired travel information is violation information instead of the process of C5 for storing this (C10). In this case, it is stored in the storage unit 8 (C11).

  On the other hand, in the center 1, the main routine is executed according to the flowchart shown in FIG. The flowchart shown in FIG. 22 is obtained by changing a part of FIG. 8 which is a flowchart of the main routine of the center 1 in the first embodiment. That is, the control device 17 of the center 1 determines whether or not the violation information transmitted from the in-vehicle device 2 is received by the communication device 18, and if it is received (YES in D10), this is stored in the storage unit. 19 (D11). Moreover, the control apparatus 17 transmits the received violation information to the portable terminal 3 by the communication apparatus 18 with vehicle information, such as license plate information (D5).

  As a result, among the vehicles 4 that have entered the designated area S, only the vehicle 4 of the vehicle-mounted device 2 that has transmitted the violation information is transmitted to the mobile terminal 3 via the center 1. Because the police officer P who is present can receive only the information of the vehicle 4 that is likely to violate even when passing through the site where the police officer P is present, it is intended to target the vehicle 4 that is driving appropriately Therefore, it becomes possible to carry out the control work in a state in which the vehicles 4 having a high possibility of violation are appropriately narrowed down.

  In addition, since only the violation information is handled in the center 1, even when the number of the target vehicles 4 becomes very large, the function of suppressing the shortage of the storage capacity of the storage unit 19 is suppressed as much as possible. Can be achieved.

(Fifth embodiment)
FIG. 23 and FIG. 24 show a fifth embodiment of the present invention. Hereinafter, parts different from the fourth embodiment will be described. In this embodiment, the process of acquiring the travel information is not performed at an appropriate timing, but is performed only when the vehicle enters the new designated area S, and only when the travel information at that time is determined to be a violation, It is intended to be transmitted.

  In this embodiment, the violation information storage routine (FIG. 21) as in the fourth embodiment is not executed at an appropriate timing, but is executed as a subroutine executed in a main routine described below.

  FIG. 23 shows the main routine of the vehicle-mounted device 2, and when the control device 5 proceeds with the process in the same manner as described above and determines that the vehicle 4 has entered the new designated area S (YES in A4), the violation information The storage routine (A30) is executed. The violation information storage routine is executed according to the flowchart shown in FIG. The control device 5 performs load amount detection (C2), speed detection (C3), and continuous operation time detection (C4) in a process similar to the violation information storage routine (FIG. 21) in the fourth embodiment. Thereafter, it is determined whether or not the detected data includes violation information (C10). If there is violation information (YES in C10), the violation information is stored in the storage unit 8, and if there is no violation information, nothing is done. To end the process and return to the main routine.

  When the control device 5 of the in-vehicle device 2 returns to the main routine, if the violation information is stored (YES in A21), the control device 5 transmits this to the center 1 (A21) and causes the display device 11 to notify the driver. (A22) The process is continued as described above.

  As a result, the in-vehicle device 2 acquires travel information only when it enters a new designated area S, stores it only when it is violation information, and transmits it to the center 1, so that necessary information is surely obtained. The storage capacity of the storage unit 8 of the in-vehicle device 2 can be reduced while adopting a configuration for transmitting to the center 1.

(Sixth embodiment)
FIG. 25 and FIG. 26 show a sixth embodiment of the present invention. Hereinafter, parts different from the first embodiment will be described.

  In this embodiment, as shown in FIG. 25, the mobile terminal 3 is configured to be able to exchange information by wireless communication with various measuring devices 30a, 30b and the like arranged at the enforcement site. Information on measurement results is received from the measurement devices 30a and 30b through the device 23 and the like.

  FIG. 26 shows a flowchart of the main routine of the mobile terminal 3, and the added functions will be described below. That is, when the control device 22 of the portable terminal 3 receives the vehicle recognition information from the center 1 (YES in E1) and displays it on the display device 27 (E2), next, from the measuring devices 30a and 30b. When violation data is transmitted, it is received and displayed (E10).

  Subsequently, the control device 22 determines whether or not the displayed violation data is a violation of the same content as that transmitted from the center 1 (E11), and if it is the same (YES in E11), It is determined that the driver is a malicious driver, the vehicle is determined to be a violation vehicle, and a display prompting for clearance is displayed (E12). This is because, when the target vehicle 4 enters the designated area S in advance, the in-vehicle device 2 determines that the vehicle is violated and the violation information is transmitted, but the measuring device 30a. When the same violation is repeated at the measurement point by 30b, it is judged that the driver is not aware of safe driving and the clearance is cleared.

  In addition, when there is no violation transmitted from the measuring devices 30a and 30b to the portable terminal 3, the violation to the driver by the in-vehicle device 2 is notified in advance, and the violation is eliminated as a result of calling attention to safe driving. As a result, the clearance is not judged (NO at E11). Further, when a violation different from the violation information transmitted from the center 1 is transmitted from the measuring devices 30a and 30b, it is separately determined whether or not the vehicle 4 is to be cleared.

  As a result, the on-site control work by the police officer P possessing the portable terminal 3 can be performed quickly and accurately, and the driver can recognize the violation information notified from the in-vehicle device 2 to the driver. It has the effect of urging you to drive safely in order to avoid culling by continuing violations.
