- Embodiments of a vehicle passage management system and a communication system for identifying vehicle according to the present invention will be discussed hereinafter in detail with reference to the accompanying drawings.
- In Fig. 1 to Fig. 6, there is shown an embodiment, in which a vehicle passage management system according to the first invention of the present application is applied to a vehicle passage management of a highway.
- Fig. 1 is a general constructional illustration of the shown embodiment of the vehicle passage management system. Referring to this drawing, a vehicle
passage management system 3 managing passage of vehicles 2(m) (m = 1, 2, 3 ...) traveling on atoll road 1 includes gates 10(n) (n = 1, 2, 3 ...) installed at a plurality of positions for coming in and our thetoll road 1, vehicle side communication devices 20(m) mounted on the vehicles 2(m), gate side communication devices 30(n) installed in the gates 10(n), and aheadquarter device 50 connected to the gate side communication devices 30(n) through radio or wired communication circuits 40(n). - Here, each vehicle side communication device 20(m) can transmit an identification information 21(m) of the vehicle 2(m) and can receive gate information 11(n) capable of identifying the passed gate 10(n). For this, each gate side communication device 30(n) can receive the identification information 21(m) of the passing vehicle 2(m) and can transmit the gate information 11(n) for identifying the gate.
- Figs. 2(A) and (B) are schematic block diagrams of the vehicle side communication device and the gate side communication device. Discussing with reference to these drawings, the vehicle side communication device 20(m) is constructed with a transmission and
reception module 21, amicrocomputer unit 22 having ROM and RAM and a vehicle mountedbattery 23 as a power source. The identification information 24 of the vehicle 2(m) is stored in ROM. The transmission andreception module 21 receives a passage management information S1 transmitted from the gate side communication device 30(n). The received information is stored and held in RAM. On the other hand, the transmission andreception module 21 is responsive to reception of a response demand signal R from the gate side communication device 30(n) to transmit the identification information 24 and the information held in RAM to the gateside communication device 30. - On the other hand, the gate
side communication device 30 includes a transmission andreception module 31 transmitting the response demand signal R, thegate information 11 and the passage management information S toward the vehicleside communication device 20 of thevehicle 2 passing through thegate 10 and receiving vehicle identification information 24 and the passage management information S2 transmitted from the vehicleside communication device 20 in response to the response demand signal R, amicrocomputer unit 32 having a toll calculating function calculating toll of thevehicle 2 passing thegate 10 on the basis of received information by the transmission andreception module 31, RAM storing the calculated toll and the received information with correspondence therebetween, and apower source 33. On the other hand, themicrocomputer unit 32 is connected to the side of thesuperior host computer 34. - Here, upon occurrence of reception failure of the transmitted information of the vehicle
side communication device 20 of thevehicle 2 passing through thegate 10, a transmittingportion 32 in the gateside communication device 30 transmits the response demand signal R again to certainly perform communication with the passing vehicle. - Next, preferred construction of the vehicle
side communication device 20 will be discussed. As set forth above, since the vehicleside communication device 20 is for transmitting the vehicle information for identifying the vehicle, it is preferable that the device cannot be arbitrarily removed by the driver. For this purpose, it is desirable to arrange the vehicleside communication device 20 in a portion of the number plate. On the other hand, the vehicleside communication device 20 has to be constantly set in a condition enabled for transmitting the vehicle identification information (namely, operating state) during driving of the vehicle. - For this purpose, it is desirable that as the power source of the
communication device 20, the vehicular battery is used, and a power supply path for thecommunication device 20 is established in the condition where a key is inserted and turned into ON position of vehicular accessories. Thus, in the vehicle driving condition, power is constantly supplied to thecommunication device 20 to enable the vehicle identification information. - In addition to the foregoing construction, in order to avoid the driver to arbitrarily set the
communication device 20 at inoperative state, it is desirable to mount an indicator lamp visually perceptible whether thecommunication device 20 is in operating state or not, from outside. - In Fig. 3, there is shown an example of mounting of the vehicle
side communication device 20 on the number plate of the vehicle. - In the example of this drawing, a number plate 70 is constructed with a box shaped
receptacle casing 71, anumber plate body 73 mounted in a side surface opening 72 of thereceptacle casing 71, a transmission andreception circuit board 74 and anantenna plate 75. On the surface of the transmission andreception circuit board 74, a transmission andreception module 76 is mounted, and also, alight emitting body 77, such as LED or the like which is illuminated while the transmission and reception circuit is in operative state, is mounted. Thelight emitting body 77 is arranged at the same position as aseal 78 mounted on thenumber plate body 73 and is covered with theseal 78. Theseal 78 is formed of a transparent material. Accordingly, thelight emitting body 77 can check illumination/extinction of thelight emitting body 77 externally through theseal 78. - Here, the
receptacle casing 71 may be entirely formed of a non-conductive material, and, also, in order to provide directionality for the built-inantenna plate 75, it may be formed of non-conductive material easy to pass a radio wave only in part. Of course, the built-inantenna plate 75 perse may be provided directionality. For example, as shown in Fig. 4, it is desirable to provide directionality in vertical direction. - Next, Fig. 5 is a flowchart showing operation of the shown embodiment of the vehicle
passage management system 3. On the gate side, it is placed in vehicle waiting state and continuously effecting call (step ST1). In this transmitting operation, presence and absence of communication at the same frequency band is detected by performing carrier sensing (step ST2). When communication is present, communication at different vacant frequency is attempted. When communication at the same frequency band is absent, the response demand signal R is transmitted (step ST3). - On the gate side, when the control signal including the
identification information 23 and the passage management information S2 are received from the side of the vehicle (step ST4), thegate information 11 of the gate is transmitted toward the vehicle (step ST5). On the gate side, when thegate information 11 is received from the gate side (step ST14), a confirmation signal indicative of reception is transmitted to the gate side (step ST15). On the side of the vehicle passing through the gate, when the confirmation signal is received (step ST6), it returns to reception waiting state again (step ST7). Similarly, even at the gate side, it returns to the waiting state (step ST16). - Thus, in the vehicle
side communication device 20, so as not to cause difficulty in recognition at the same frequency when a plurality of vehicles enter into the gate in series, carrier sensing is performed with the gate side before performing communication, to perform communication with automatically switching to a vacant channel frequency. Accordingly, even when a plurality of vehicles are in series, communication with each vehicle can be performed certainly. - Next, in the shown embodiment of the vehicle passage management system, so that the vehicular driver may check whether the mounted communication device is in operative condition or not, announcing means for announcing the condition is desirably arranged in an operating portion of a driver's seat. The announcing means may be an indicator lamp mounted on an operation surface of the driver's seat of the vehicle or a audio indication means, such as speaker or the like, mounted on the driver's seat. Of course, both of these may be provided. Such announcing means mat take the vehicular battery as a driving power source so that it is turned ON and OFF according to ON and OFF of in-vehicle accessory power source.
- Here, in the shown embodiment of the vehicle
passage management system 3, each gate 10(n) is a double gate system. Namely, as shown in Fig. 6, each gate 10(n) has acommunication gate 30A and a checkinggate 30B. Thecommunication gate 30A has the gate side communication device 30(n) of the construction set forth above for transmitting and receiving the gate information and the vehicle identifying information with the passing vehicle. Thecheck gate 30B is located at the frontal side of the communication gate in vehicle traveling direction, and when transmission and reception of the gate information and the vehicle identification information in the communication data is not performed properly, entry of the vehicle into thetoll road 1 is inhibited. - As set forth, in the shown embodiment, each gate is the double gate system. With this construction, it can announce that the vehicle side communication system is not in operation.
- On the other hand, in the gate 10(n) of the shown embodiment, an
exit road 30C is provided for returning the vehicle which cannot enter the highway to the open road from thecheck gate 30B. In this case, by forming abranched road 30D returning to the toll road at the midway of theexit road 30C, and by installing agate 30E having a ticket issuing machine issuing an entry ticket to the highway, even the vehicle causing failure of the communication device may use the highway in normal manner of use. - It should be noted that the foregoing discussion is the embodiment, in which the present invention is applied to the passage management system of the highway. The present invention is equally applicable as the passage management system of the vehicle in a parking lot. Also, the invention is equally applicable for the passage management system for the vehicle coming in and out to particular area, such as factory site or so forth.
- Next, discussion will be given for one example of the communication system for identification of the vehicle to be used in the vehicle passage management system according to the present invention with reference to Fig. 7 to Fig. 11.

microcomputer unit 42, a storage region storing an identified vehicle information list storing the identification information of the identification objective vehicles is formed. The identified vehicle information list is supplied from the side of the host computer, for example. Themicrocomputer unit 42 has a judgment function for making judgment whether theidentification information 5S of the passingvehicle 105 received via the transmission andreception module 41 appears on the identified vehicle information list or not under control of CPU. On the other hand, an announcing function for announcing the fact when the passing vehicle 5 is judged as the vehicle appearing on the identified vehicle information list. On the side of thehost computer 44, when the signal indicative of passing of the vehicle as object for identification is received from themicrocomputer unit 42, the fact is displayed on a display screen of thedisplay device 45 for providing alarm to an operator. - On the other hand, a transmission control function transmitting a continuous transmission demand signal R1 to the vehicle
side communication device 106 of the vehicle via the transmission andreception module 41 of the gateside communication device 4, when themicrocomputer unit 42 of the gateside communication device 104 further detects passing of the identification objective vehicle. - In Fig. 9, the construction of the vehicle
side communication device 106 is shown. At first, as shown in Fig. 9(A), the vehicleside communication device 106 is constructed with a transmission andreception module 61, amicrocomputer unit 62 and avehicular battery 63 as a power source. - As shown in Fig. 9(B), the
microcomputer unit 62 includes a data transmitting and receivingIC 621,CPU 622, EEP-ROM 623, D-RAM 624, aninterface portion 625 with peripheral devices, and so forth. Theidentification information 5S of thevehicle 105 is stored in EEP-ROM 623. The passage management information received via the transmission andreception module 61 is also stored and held in EEP-ROM 623. When the response demand signal R is received via the transmission andreception module 61, thevehicle identification information 5S and the passage management information S2 held in the EEP-ROM 623 are transmitted to the gateside communication device 4 via the transmission andreception module 61. - On the other hand, the
microcomputer unit 62 of the vehicleside communication device 106 has an announcing signal transmission control function for continuously or intermittently transmitting an announcing signal WS indicative that the vehicle 5 is the identification objective vehicle via the transmission andreception module 61 of the vehicleside communication device 106 when the continuous transmission demand signal R1 is received via the transmission andreception module 61 of the vehicle side communication device 6. - Here, since the
vehicle communication device 106 is adapted to transmit thevehicle identification information 5S for identifying the vehicle, it is desirable to arranged on a portion of the number plate so that it may not be subject to arbitrary removal or so forth on the side of the driver. - On the other hand, the vehicle
side communication device 20 has to be constantly set in a condition enabled for transmitting the vehicle identification information (namely, operating state) during driving of the vehicle. For this purpose, it is desirable that as the power source of the communication device 6, the vehicular battery is used, and a power supply path for thecommunication device 106 is established in the condition where a key is inserted and turned into ON position of vehicular accessories. - In addition, in order to avoid the driver to arbitrarily set the
communication device 106 at inoperative state, it is desirable to mount an indicator lamp visually perceptible whether thecommunication device 106 is in operating state or not, from outside. - Next, Fig. 10 is a flowchart showing operation of the shown embodiment of the vehicle
identification communication system 400. - At first, on the side of
gate 103, it is placed invehicle 105 waiting state and continuously effecting call (step ST201). In this transmitting operation, presence or absence of communication at the same frequency band is detected by performing carrier sensing (step ST202). When communication is present, communication at different vacant frequency is attempted. When communication at the same frequency band is absent, the response demand signal R is transmitted (step ST203). - Upon approaching to the
gate 103 in waiting state capable of reception and reception of the response demand signal R (step ST211), the vehicleside communication device 106 of thevehicle 105 passing through thegate 103, performs carrier sensing (step ST212) to transmit theidentification information 5S, the passage management information S2 and so forth of the vehicle 5 to the gateside communication device 4 at a wavelength of the vacant frequency band (step ST213). - On the gate
side communication device 104, When the control signal including thevehicle identification information 5S and the passage management information S2 are received from the side of the vehicle side communication device 106 (step ST204), thegate information 3S of thegate 103 is transmitted toward the vehicle side communication device 106 (step ST205). - Upon reception of the
gate identification information 3S from the gate side communication device 4(step ST 214), the vehicleside communication device 106 transmits the confirmation signal indicative of reception, to the gate side communication device 104 (step ST215). Upon reception of this confirmation signal (step St206), the vehicleside communication device 106 of thevehicle 105 passing through thegate 103 returns to the waiting state again (step ST207). Similarly, even the gateside communication device 104 returns to the waiting state (step ST216). - Thus, in the vehicle
side communication device 106, so as not to cause difficulty in recognition at the same frequency when a plurality of vehicles enter into the gate in series, carrier sensing is performed with the gate side before performing communication, to perform communication with automatically switching to a vacant channel frequency. Accordingly, even when a plurality of vehicles are in series, communication with each vehicle can be performed certainly. - Here, in Fig. 11, there is shown a general flowchart of judgment operation of the identification objective vehicle to be performed at every time of passing of the vehicle in the gate

Upon matching, the fact is announced to thehost computer 44. As a result, on the screen of thedisplay device 45, an alarm display of the fact is performed (step ST222). For example, when the identification objective vehicle is that on the stolen vehicle list, displaying of passage of the stolen vehicle is performed. Subsequently, the continuous transmission demand signal R1 is transmitted via the transmission andreception module 41 toward the vehicleside communication device 106 of the passed vehicle 105 (step ST223). - On the side of the vehicle
side communication device 105 of thevehicle 105, upon reception of the continuous transmission demand signal R1 (step 231), it continues transmission of the alarm signal WR indicative that thevehicle 105 is the identification objective vehicle (step ST 232), and other operation is forcedly placed in enabled condition. - The foregoing embodiment is an example of the case where the
gate 103 is installed on the roadside. In stead, thegate 103 may be portable type. For example, with a vehicle mounting type gate, identifying operation of the passing vehicle can be performed at desired site.
