Traffic management system and traffic management device

Technical field

TECHNICAL FIELD [0001] The present invention relates to a traffic management system and a traffic management device, and in particular, based on the traffic rules indicated in the received information, the information regarding traffic rules to be implemented from the outside can be received by high-speed wireless communication. The present invention relates to a traffic management system and a traffic management device that perform processing on a vehicle according to the driving state of the vehicle.

Background art

[0002] Conventionally, vehicles such as automobiles are provided with a license plate that allows the registration number to be visually confirmed, and based on this registration number, the driver of the vehicle is allowed to comply with traffic rules by controlling speeding. I have done it. In addition, license plate readers have been installed on main roads, etc., and the license plates of vehicles passing near the reader have been memorized and used to find stolen vehicles and for crime investigations.

[0003] Currently, in order to solve problems such as traffic jams, traffic accidents, and environmental burdens using state-of-the-art information and communication technology (IT), research and commercialization of ITS intelligent Transport System is daily. Among them, a system called a probe car is currently being tested.

[0004] This is because the vehicle itself functions as a sensor, and information such as the vehicle position and traveling speed obtained from the ECU (Electric Control Unit) of the traveling vehicle is recorded at regular intervals by an on-board device mounted on the vehicle. By transmitting wirelessly to the center, it is possible to provide information such as traffic congestion information that changes in real time, or to detect speed violations by reproducing the travel route based on the record. .

[0005] However, in this conventional apparatus, the information that also obtains the recorded information power in the memory is only the average speed from the start of the vehicle to the end of the vehicle. The supervisor was unable to give instructions to improve the safety of the driver's actions in the memory of recorded information.

[0006] Therefore, the vehicle travels while receiving speed information and the like, and is installed on the road. Has been proposed to receive information (for example, Patent Document 1). When the vehicle starts running, the driver's information including the license number, date of birth, current address, permanent address, and traffic violation information read from the IC license whose license information is stored in the IC card, and the vehicle The information transmission unit force always transmits the vehicle identification information of the information unit, the current vehicle speed, and the vehicle information including the seat belt wearing situation. As a result, traffic violations such as speeding violations and seed belt non-wearing violations can be easily controlled.

[0007] In addition, it is proposed that information on traffic rules received by roadside transmitter power is compared with information obtained by the operation information acquisition means installed in the vehicle, and violation information is transmitted to the outside ( For example, Patent Document 2). It is also proposed that the vehicle-mounted device reads the traffic information installed on the road, detects the speed, etc., determines whether there is a traffic violation, issues a warning if a violation is predicted, and sends it to the enforcement center. (For example, Patent Document 3).

Problems to be solved by the invention

However, the traffic management system described in Patent Document 1 uses EEPRuM (Electronically Erasable and Programmable Read Only Memory) flash memory as an IC card. The memory access speed is very slow when applied to a vehicle moving at high speed, for example, it takes about 3ms for an EEPROM and about 1 second for a flash memory, especially 120kmZ on a highway. If time is converted, it will travel 33 meters per second. Therefore, if other data communication and data processing times are added, the vehicle will move away from the receiving device that receives data from the vehicle before the data is converted. Therefore, the monitoring effect was not sufficient.

[0009] Similarly, in the traffic management system described in Patent Document 2 and Patent Document 3, since the reading speed from the IC card and the writing speed to the IC card are slow, the sufficient monitoring effect is I had no power. If transfer speed is slow, before transferring data There was a problem that traffic management could not be performed sufficiently because the vehicle passed and was far away.

[0010] The present invention has been made in view of such problems, and enables information regarding traffic rules to be implemented from the outside to be received by high-speed wireless communication, and based on the traffic rules indicated in the received information. The purpose is to provide a traffic management system that performs traffic regulation processing according to the driving state of the vehicle.

In FIG. 6, the same components as those in FIG. 2 are denoted by the same reference numerals, and the description thereof is omitted. Figure 6 In the configuration of the traffic management system 1002 shown, the traffic regulation process is executed on the vehicle 102 side, and the program is not stored in the IC chip 220 of the IC card 22 and only the information is recorded.

Therefore, in addition to the configuration of the vehicle 101 shown in FIG. 2, the vehicle 102 includes a recording unit 212, a speed information recording unit 213, a vehicle information recording unit 214, and road periphery information in the IC chip 210 in FIG.

[0056] Further, the vehicle 102 has a communication function with the IC force 22 in addition to the IC card communication device 11 of the vehicle 101 shown in FIG. ing.

[0057] The control unit 1 lb for executing the traffic regulation process has a CPU (Central Processing Unit), has a function equivalent to the IC card communication device 11 shown in FIG. 2, and communicates with the portable medium 20 At the same time, communication between the wireless communication control device 12, the engine control device 13, the interface 14, the display control device 15, and the portable medium 20 is performed.

[0058] In addition, the control unit l ib executes access from the recording units 212b to 215b and 219b at high speed. Then, the control unit ib reads the traffic regulation program from the traffic regulation program recording block 219b and performs traffic regulation processing on the vehicle 102.

In the configuration of the vehicle 102 shown in FIG. 6, at least the recording unit 212b and the traffic regulation program recording unit 219b are configured by a nonvolatile memory. The vehicle 102 can perform processing at higher speed using DRAM (Dynamic Random Access Memory).

In vehicle 102, IC card 22 is a card on which IC chip 220 is mounted.

The IC chip 220 has a control unit 221, a recording unit 222, a speed information recording unit 223, a vehicle information recording unit 224, and a terminal 226 for communicating with the IC card communication device 11 of the vehicle 102. The Since the IC chip 220 is only for data recording, it is configured using a nonvolatile memory using a ferroelectric such as FRAM (registered trademark) to realize high-speed processing.

The control unit 221 has a CPU (Central Processing Unit), and causes the vehicle 102 to perform traffic regulation processing via the terminal 226. Terminal 226 can be contact or non-contact ,. Any structure may be used as long as the IC card 21 is supported around the IC card communication device 11 in a state where the IC card 21 can stably communicate with the IC card communication device 11 in contact or non-contact.

Next, traffic regulation processing executed by the traffic regulation program will be described with reference to FIGS. 7 and 8 are diagrams for explaining the traffic regulation program processing according to the embodiment of the present invention. In the description of FIGS. 7 and 8, the vehicle 101 and the vehicle 102 are collectively referred to as a vehicle 1.

In FIG. 7, when the current speed information A is acquired, the traffic regulation process records the current speed information in the speed information recording unit 213 along with the current time (step S101). Then, the traffic regulation process determines whether or not the speed A indicated in the current speed information A is slower than the predetermined high speed value SP80 (step S102). The predetermined high speed value SP80 is, for example, 80 kmZh as a standard speed limit on a highway. If the current speed information A is equal to or faster than the predetermined high speed value SP80, the traffic regulation process proceeds to step S110 in FIG.

[0067] On the other hand, when the current speed information A is slower than the predetermined high speed value SP80, the traffic regulation processing further takes a time equal to the time when the current speed information A recorded in the road periphery information recording unit 215 is acquired. Alternatively, it is determined from the vehicle surrounding information of the closest time within a predetermined time whether or not the force has acquired the speed limit information C indicating the speed limit C on the running road (step S103). The speed limit C is a reference speed for limiting the traveling speed of normal roads, not highways.

[0068] If the speed limit information C cannot be obtained, the traffic regulation processing is performed at the time when the current speed information A is obtained from the road surrounding information recording unit 215, or within the predetermined time. It is determined whether there is other traffic rule information 35 (step S103-2). sand That is, it is determined whether or not there is traffic rule information 35 indicating traffic rules other than the speed limit. If there is another traffic rule 35, the traffic regulation process proceeds to step S107.

[0069] On the other hand, if it is determined in step S103-2 that there is no other traffic rule 35, the traffic control process is continued for vehicle 1 (step S109) and is terminated. The traffic regulation process is resumed from step S101 by acquiring the current speed information A.

[0070] If it is determined in step S103 that the speed limit information C has been acquired, the traffic regulation processing subtracts the speed C indicated by the speed limit information C from the speed A indicated by the speed limit information A ( In the following, it is determined whether or not A−C difference is smaller than the preset first speed difference NSD20 (step S104). When the A—C difference is equal to the first speed difference NSD20 and is V, or larger, the value proceeds to step SI 1 0-2 in FIG. The first speed difference NSD20 is a value for which it is determined that speed limitation is essential on general roads. For example, the difference from the speed limit is 20kmZh.

On the other hand, if the A−C difference is smaller than the first speed difference NSD20, the traffic regulation process determines whether or not the A−C difference and the second speed difference NSD15 are smaller (step S105). If the A-C difference is equal to or greater than the first speed difference NSD15, display control device 15 displays a message warning that vehicle 1 is above the speed limit and that the speed needs to be reduced. (Step S 105-2), the process ends. The second speed difference NSD15 is a value for which it is judged that a warning is indispensable even if the speed is not forcibly restricted on ordinary roads. For example, the difference from the speed limit is 15 kmZh.

[0072] On the other hand, if the A−C difference is smaller than the first speed difference NSD15, the traffic regulation process determines whether or not there is other traffic rule information (step S106). That is, it is determined whether or not there is traffic rule information 35 indicating traffic rules other than the speed limit. If there is another traffic rule 35, the traffic regulation process proceeds to step S107. On the other hand, when there is no other traffic rule information, the traffic regulation process is terminated after the vehicle 1 continues normal operation (step S109). The traffic regulation process is resumed in step S101 by acquiring the current speed information A.

[0073] The traffic regulation process includes other traffic rules 35 in steps S103-2 and S106. If so, it is determined whether or not the force is in a travel state that needs to be restricted (step S107). For example, it is determined whether or not other traffic rules 35 indicate one or more of slowing information, pause information, and the like. If the travel state does not need to be restricted, the traffic regulation process ends with the vehicle 1 continuing normal operation (step S109). The traffic regulation process is resumed from step S101 by acquiring the current speed information A.

[0074] On the other hand, if it is determined in step S107 that the travel state requires restriction, the traffic restriction process further determines whether or not other traffic rules 35 are being observed (step S). 108). For example, if the other traffic rule 35 is slow information, it is determined whether or not the speed A indicated in the current speed information A is less than 20 kmZh. If the other traffic rule 35 is time stop information, it is determined whether or not the vehicle is stopped within a predetermined time range including the time of the current speed information A and the current speed information A.

[0075] In step S108, when the other traffic rules 35 are observed, the traffic regulation processing is continued after the vehicle 1 continues normal operation (step S109), and ends. The traffic regulation process is resumed from step S101 by acquiring the current speed information A.

[0076] On the other hand, if other traffic rules 35 are observed! /, Na! /, The traffic regulation processing causes the display control device 15 to display the traffic rules shown in the other traffic rules 35 (step S108— 2) Finish. The traffic regulation process is restarted from step S 101 by acquiring the current speed information A.

[0077] In step S102, when the speed A indicated in the current speed information A is equal to or higher than the predetermined high speed value SP80, the process proceeds to step S110, and it is assumed that the vehicle is traveling on a highway. Then, the control shown in FIG.

[0078] In FIG. 8, in step S110, the speed regulation process is closest to the time when the current speed information A is acquired from the road periphery information recording unit 215! It is determined whether or not highway information indicating that the road has been acquired (step S110).

[0079] If it is determined in step S110 that highway information has not been acquired, the speed regulation process determines that the vehicle is traveling on a general road and starts automatic control for the vehicle 1 (step S110). — 2). That is, the speed regulation process is reduced with respect to the engine control device 13. Give instructions to speed. Then, the vehicle 1 is forcibly decelerated to a speed based on the predetermined high speed value SP80 in the case of the process following step S110 or in the case of the process subsequent to step S102, based on the speed limit information C on the general road. In this case, for example, when the running state of the vehicle 1 is unstable, automatic control may be performed so that the vehicle 1 is stopped.

[0080] In the speed regulation process, traffic violation information based on the traffic rule information 35 is further recorded in the recording unit 212 (step S110-4). In step S110-4, the speed regulation process may notify the radio communication control device 12 of traffic violation information. In this case, violation information 39 created by the wireless communication control device 12 based on the traffic violation information is transmitted via the transmission / reception unit 12a. Thereafter, the speed regulation process ends.

[0081] On the other hand, if it is determined in step S110 that the highway information has been acquired, the speed regulation process obtains the speed limit information B indicating the speed limit B on the highway from the road periphery information recording unit 215. Judgment is made on whether or not the force was acquired (step Sl ll). The speed limit B is a reference speed for limiting the driving speed on the highway. Speed limit B is faster than speed limit C.

[0082] When it is determined that the speed limit information B cannot be obtained, the speed restriction process determines whether or not the current speed information A is slower than the predetermined high speed value SP 130 (step S112). As the predetermined high speed value SP 130, a speed corresponding to a speed violation is set on the highway, for example, 130 kmZh. If the current speed information A is equal to or faster than the predetermined high speed value SP130, the speed regulation process proceeds to step S110-2 to start automatic control.

On the other hand, when it is determined in step S112 that the current speed information A is slower than the predetermined high speed value SP130, the speed rule processing further determines whether or not the current speed information A is slower than the predetermined high speed value SP120. (Step S113). As the predetermined high speed value SP120, an allowable speed within the range of normal driving on the highway is set, for example, 120 kmZh. If the current speed information A is equal to or faster than the predetermined high speed value SP120, the speed regulation process causes the display controller 15 to display a message warning that the speed limit on the highway has been exceeded. (Step S 113-2), the process ends.

[0084] On the other hand, when it is determined in step S113 that the current speed information A is slower than the predetermined high speed value SP120, the traffic regulation process is continued for vehicle 1 (step S114) and is terminated. The The traffic regulation process is resumed from step S 101 by obtaining the current speed information A.

[0085] If the speed limit information B can be acquired in step S111 described above, the speed control process reduces the speed B indicated by the speed limit information B from the speed A indicated by the speed limit information A. It is determined whether or not the calculated difference (hereinafter referred to as “A−B difference”) is smaller than the preset third speed difference HSD30! (Step S115).

[0086] If the A—B difference is equal to or greater than the third speed difference HSD30, the speed control process will cause the vehicle 1 to be automatically controlled and decelerated because the speed limit is significantly exceeded. A warning message is displayed on the display control device 15 (step S115-2). Proceed to step S110-2 to limit the speed of vehicle 1. The third speed difference HSD30 is a value that is considered to require speed limit on the expressway. For example, the difference from the speed limit is 30kmZh.

On the other hand, if the A−B difference is smaller than the third speed difference HSD30, the traffic regulation process determines whether or not the A−B difference is smaller than the fourth speed difference HSD20 (step S116). A— B If the difference is equal to or greater than the fourth speed difference HSD20, a message is displayed on the control device 15 that warns the vehicle 1 that it is above the speed limit and that the speed needs to be reduced. (Step S116-2) and finish. The fourth speed difference HSD20 is a value for which it is judged that a warning is indispensable even if the speed limit is not compulsorily restricted on a highway. For example, the difference from the speed limit is 20 kmZh.

[0088] On the other hand, if the A−B difference is smaller than the first speed difference HSD20, the traffic regulation process is continued for the vehicle 1 (step S117), and is terminated. The traffic regulation process is resumed from step S101 by acquiring the current speed information A.

[0089] Predetermined high speed value SP80, predetermined high speed value SP130, predetermined high speed value SP120, first speed difference NSD20, second speed difference NSD15, third speed difference HSD30, fourth speed difference HSD20, etc. May be described in the program, or may be set as a table in a predetermined storage area in the traffic control program recording unit 219 or 219b.

[0090] A warning message displayed on the display control device 15 by the traffic control process as described above. The sage is, for example, a message as shown in FIG. FIG. 9 shows an example of a message displayed by the traffic control process.

FIG. 9A shows an example of a message displayed on the display control device 15 in step S105-2 in FIG. For example, “15kmZh or more exceeds the speed limit.

Please drive safely. "And so on.

FIG. 9B shows an example of a message displayed on the display control device 15 in step S108-2 in FIG. For example, “Warning. You ignored“ pause ”. "Is displayed.

FIG. 9C shows an example of a message displayed on the display control device 15 in step S115-2 in FIG. For example, “The speed exceeds 30kmZh from the speed limit. After a few seconds, the automatic control that decelerates and stops starts.” Is displayed.

[0094] In the traffic regulation process shown in FIGS. 7 and 8, such a message may be displayed as appropriate based on the excess speed, traffic rules, and the like.

[0095] When the above warning message is displayed on the display control device 15, the driver may be notified by voice, warning sound, or the like.

[0096] As described above, according to the present invention, the traffic rule radio 300 installed on the roadside or the like and the vehicle 1 can communicate at high speed, and data processing between the vehicle 1 and the portable medium 20 can be performed at high speed. Since it is feasible, automatic control such as warning or deceleration of the vehicle 1 can be performed in a timely manner.

[0097] Further, in order to calculate the speed difference between the traffic rule information 35 of the traffic sign 30 and the current speed, the driver of the vehicle 1 is warned and forcibly decelerated according to the level of the speed difference. Automatic control can be started. It can also be controlled by stopping the vehicle 1 after decelerating.

[0098] Further, in the recording unit 212, the driving history information is cyclically overwritten and used, and the traffic violation record information is recorded in a predetermined recording area that cannot be erased and overwritten. Therefore, it is possible to refer to the traffic violation content and the driving state at the time of the traffic violation from the traffic violation record information, and to confirm the latest driving state by referring to the driving history information.

[0099] When the vehicle 1 receives the traffic rule information 35, the traffic rule information 35 is displayed. By notifying them by voice, it is possible to prevent oversight of road signs and traffic lights due to bad weather or roadside trees and other physical factors and lack of driver attention. Therefore, intentional traffic violations by the driver can be prevented from being allowed. Therefore, it is possible to prevent traffic accidents due to intention or carelessness and to reduce the number of occurrences.

[0100] Furthermore, since the violation information is notified from the vehicle 1 to the traffic control management system via the traffic rule radio 300, it can be verified as information on the vehicle 1 such as when the vehicle 1 is stolen. Become.

[0101] In order to respond to traffic violations in a more timely manner, it is desirable that high-speed data transfer, high-speed data processing, and long service life be achieved.

[0102] In order to achieve high-speed data transfer, the communication between vehicle 1 and traffic rule radio 300 is 1Mbit per second using an infrared ray, high-speed wireless LAN, GPS (Global Positioning System), etc. (1Mbps) or more. Apply a broadband frequency that enables high-speed communications.

[0103] Further, by adopting the configuration of the portable medium 20 as described above for high-speed data processing, the access time for writing and reading in the portable medium 20 can be reduced to 100 sec or less.

[0104] Furthermore, in order to extend the life, an IC chip having a performance of FR AM (registered trademark), PRAM, OUM, or more, which is 10 10 (10'10) or more times of rewriting is mounted. Use an IC card.

In the above-described embodiments, the following mechanism can be applied.

[0106] As information that can be detected by vehicle 1, in addition to the current speed signal that indicates the current speed, a signal that indicates whether the seat belt is worn or not is used as traffic rule information 35. However, it may be recorded in the recording unit 212 as traffic violation record information. In this case, display a message warning that it is a traffic violation on the display controller 15.

[0107] The vehicle 1 stores information that can identify the driver corresponding to the license information stored in the portable medium 20 in a predetermined storage area in advance, and is stored in the portable medium 20. The driver's license information and the information stored in the specified memory area that can identify the driver match. In this case, the various information described above is recorded on the portable medium 20. By having such a mechanism for confirming the coincidence of the information relating to the driver, it is possible to control the engine so that it does not use power when the information relating to the driver does not coincide. Such control makes it possible to prevent the vehicle 1 from being stolen. In addition, the owner of the vehicle 1 can be specified.

[0108] The driver's fingerprint data is stored in the vehicle 1 and the portable medium 20 in place of the driver's license information and the driver-identifiable information. The engine power may be applied. In addition, in order to increase security, the vehicle 1 is provided with a fingerprint reading device that reads the fingerprint of the driver's finger, and the portable medium is obtained by matching the fingerprint data stored in the vehicle 1 with the fingerprint data read by the fingerprint reading device. The fingerprint data stored in 20 and the fingerprint data read by the fingerprint reader are matched, or the fingerprint data stored in the vehicle 1 and the portable medium 20 are matched with the fingerprint data read by the fingerprint reader. Let's make the engine work on vehicle 1! ,.

[0109] Further, in the traffic management system 1002, information that can identify each driver is stored for a plurality of drivers of the vehicle 1, and various information is recorded in the vehicle 1 for each driver. Thus, it is possible to verify in which driving state by which driver the vehicle 1 was used.
