It transmits the information to the field device 30 through CDMA, IMT-2000 or wired communication network, and additionally receives the current speed information of the vehicle from the field device 30 to calculate statistical data in various surrounding areas. Perform.

The field device 30 receives information on the speed limit and road control in each road section transmitted from the center system 20, and transmits the received details to the center system 20. At the request of 20), the overall driving situation of the field apparatus 30 is transmitted to the center system 20.

In addition, the field device 30 performs digital local broadcasting on the road speed and traffic control information for each section of the road through short-range wireless communication for all vehicles passing through the surrounding area. All information received from the device 40 is converted into statistical indicators and transmitted to the center system 20.

The vehicle device 40 receives information of the speed limit for each section transmitted from the field device 30 and temporarily stores it. The current driving speed is provided through an engine control device / shift control device / separate speed measurement device mounted in the vehicle. If the driving speed of the vehicle is determined to be driving over the speed limit legally regulated in the corresponding section, the driver first outputs a warning sound to induce the driver 50 to slow down. In addition, the fuel flow flowing into the engine is blocked secondly so that the driving speed can be automatically reduced.

If the vehicle decelerates below the limit speed in the corresponding section by blocking the amount of fuel flowing into the engine, it detects this in real time so that the normal amount of fuel is automatically introduced into the engine.

As can be seen in FIG. 2, the field device 30 includes the main controller 31, the RF module 32, the communication port 33, the memory 34, the wired communication module 35, and the main controller 31. It consists of a wireless communication module 36, the main controller 31 transmits and receives information through the center system 20 and the wired communication module 35 or the wireless communication module 36 using the communication port 33. And control the RF module 32 for the vehicle and wireless transmission and reception in the field.

In addition, it performs a basic function of storing, recording and managing the general information received from the vehicle and the information to be output to the driver 50 in the memory 34.

The RF module 32 performs two-way wireless communication between the field device 30 and the vehicle device 40 through the CDMA / IMT-2000 / DSRC method, 400 MHz band, or 200 MHz band, and basically receives driving speed information of the vehicle. Then, the main controller 31 is informed about the speed limit in the corresponding section indicated by the center system 20 to perform local broadcasting in the field.

The communication port 33 transmits general information received from the main controller 31 to the center system 10 through the wired communication module 35 or the wireless communication module 36 or from the center system 10. Receive general information related to speed limit and traffic restriction by road section.

The memory 34 temporarily stores the speed limit information for the corresponding section received from the center system 10 through the communication port 33 and all the information received from the vehicle device 40 under the control of the main controller 31. It is in charge of the record management function, and notifies the master controller 31 of the speed limit information received and managed from the center system 10 as voice information.

In addition, as shown in FIG. 3, the vehicle device 40 includes a main controller 41, an RF module 42, an engine control device / vehicle measurement device 43, an output device 44, and a memory ( 45) and the fuel cutoff module 46, the main controller 41 receives all the information transmitted by the field device 30 through the RF module 42, and stores it in the memory 45, the vehicle Real-time communication with the engine control device / vehicle speed measurement device 43 to request the current speed of the vehicle and to receive related information, and to store the information received from the engine control device / vehicle speed measurement device 43 into the memory 45. Compare with the speed limit in the section in which the record is being managed.

At this time, when the current vehicle speed exceeds the speed limit in the comparison result, the warning signal and voice information are called from the memory 45 and the driver 50 shown in FIG. 1 is alerted through the output device 44. And, if the driver 50 does not reduce the speed to less than the speed limit within a certain time to control the fuel cutoff module 46 immediately to block the amount of fuel flowing into the engine.

If the current speed of the vehicle is maintained below the speed limit in the overspeed state, the main controller 41 immediately stops the function of the fuel cutoff module 46 to control the normal amount of fuel to be injected into the engine.

The RF module 42 is a module that transmits and receives speed limit information for each section through wireless communication with the field device 30, and is a standard set by the Intelligent Transportation System (ITS) which is an advanced transportation system using a wireless digital communication method. Therefore, the wireless communication system such as CDMA / IMT-2000 / DSRC and 400MHz / 200MHz band digital wireless communication module and infrared communication module including active type module of 5.8GHz band.

The engine control device / speed measurement device 43 provides the main controller 41 with information on the current vehicle speed in accordance with the information request signal of the main controller 41.

The memory 45 stores the speed limit for each section received from the field device 30 and voice information data for decelerating the current vehicle speed under the control of the main controller 41, and the current vehicle speed for each section exceeds the speed limit. If it is determined that the vehicle is operating by outputting the voice information data to decelerate the vehicle speed at the request of the main controller (41).

The fuel cut-off module 46 cuts off the amount of fuel supplied to the engine through the shut-off of the fuel pump or the injector according to the control signal applied from the main controller 41 when the vehicle speed by the current section exceeds the speed limit. When the vehicle speed is maintained below the speed limit, and the vehicle speed is kept below the speed limit, the amount of fuel supplied to the engine is restored by restoring the driving of the fuel pump or the injector by a control signal applied from the main controller 41. To restore normal driving.

The field device 30 may be installed by using various features, and the main device is different depending on the national road / general national road, highway, and urban intersection, etc., but the main object is mainly installed using a signal signal, a signal controller, a street lamp, and a signage. do.

As an example, the field device in the urban road becomes the main installation position of the signal controller, the street lamp, and the signal signal, and when the street controller is installed in the street lamp, the distance between the intersections is a section of the Super Block, In the case of highways, current regulations may limit the speed limit along the highway lines and the passage speeds of some sections.Therefore, if restricted by the route, install it at the entrance of the toll plaza or the street lamps around it. In the case of limiting speed in some sections of the highway, it is installed in a variable signboard and street lamp or central divider and shoulder curb as a neighboring feature.In the case of national road, it has both characteristics of urban road and highway. The principle of setting up roads and highways is compromised, and accordingly, And value.

The field device installation requirements described above are very important because the field device 30 performs wireless communication with the vehicle as an RF module, and the selection of the point at which the speed limit information is transmitted to the vehicles and the speed limit can be ignored. Since the speed limit regulation point and mitigation point should be selected, the installation requirements for this are as follows.

In the case of installing the field device according to the characteristics of each section on one road, for example, as shown in Figure 4, when installing the field device for each section on the center line or the center separator of the road based on the direction of the vehicle 1 Install the field device 30 at the inlet (①) to broadcast the omnidirectional speed limit with information about 80 km / h, and install the field device 30 at the outlet (②) to limit the forward speed. Local broadcasting with information about 70 km / h, and when the field device 30 is installed in the outlet part ③ to set the forward speed limit to the free speed section, while the vehicle 1 passes the speed limit section ⓐ Locally, the speed limit of 80 km / h is transmitted directly from the field device 30 installed at the inlet part ①, and when the vehicle 1 arrives at the outlet part ②, the site installed at the outlet part ②. Device 30 belongs to vehicle 1 Termination restriction and so the next rate-limiting region ⓑ state in which the progress of local broadcast a forward speed limit to 70Km / h with respect to the vehicle 1 is subjected directly to the passage speed limit impact of 70Km / h is the local broadcast.

In addition, when the vehicle 1 arrives at the outlet portion ③, the field device 30 installed in the outlet portion ③ is a state where the speed limit is canceled and the omnidirectional speed limit is broadcasted as a free speed section. This ensures that all movements to the vehicle are maintained at normal speeds so that the vehicle can run at the highest speed it can achieve.

As described above, when the field apparatus locally broadcasts the speed limit information for each section, most roads are configured as roads capable of two-way traffic, as the traveling directions of vehicles 1 and 2 are maintained opposite to each other in FIG. 4. When the field device 30 must know the direction of movement of the vehicle when the normal speed limit system can be operated.

As an example of this, in the case of locally broadcasting information of a speed limit of 70 km / h from the outlet section ② to the vehicle 1 that has passed section ⓐ in FIG. 4, the section ⓐ is driven in the opposite lane. The vehicle 2 that intends to drive also has a problem in that it drives the section ⓐ at a speed limit of 70 km / h.

In order to solve this problem, in the present invention, the field apparatus locally broadcasts the communication data in the data format as shown in FIG. 5.

As can be seen in FIG. 5, the data format has a format in which all fields are composed of 1 byte, but in the case of a check sum field, the format is 2 bytes.

In data format, the Start Code means the start of every frame transmitted and consists of 1 byte. The Data Length is the total number of bytes of all transmission data including the self before the checksum. It consists of 1 byte, the current node (Current Node) is a unique ID of the field device that is transmitting information through local broadcasting, consisting of 1 byte, 'ToNode1' to 'ToNode4' based on the field device The unique ID of the field device at the end of the adjacent speed limit section consists of 1 byte, and 'No.of Destine' means the total number of sections defined in the transmission data. It consists of 1 byte and consists of 4 intersections. In the case of limiting speed to adjacent intersections according to the above type, 'No. of Destine 'becomes four.

In addition, 'Speed1' to 'Speed4' designate a speed limit for each section. For example, 'Speed1' is a speed limit from a current node to a 'ToNode1', and in the case of 'Speed2', a current node It means the speed limit from (Current Node) to 'ToNode2' and consists of 1 byte.

The format of the above data format has a variable scalability for three intersections or four or more roads at an urban intersection.

Referring to the operation of controlling the vehicle speed for each section of the road in the present invention having the technical characteristics as described above are as follows.

When the operation of the system is started, the center system 20 is the speed limit and the road in each road section from the road information provider 10, the Korea Highway Corporation 11, the National Highway Administration 12, the National Police Agency and the local government 13 After collecting the information on the control of the CDMA / information on the speed limit and the road control to the field device 30 installed in each section by the characteristics / type of the road as shown in the example of Figure 4 attached to each information When transmitted through the wireless communication or wired communication network of the IMT-2000 system, the main controller 31 of the field device 30 is a communication port 33 for interfacing the wired / wireless communication modules 35 and 36 from the center system 10. While storing and managing the information of the speed limit for each section received in the memory 34 in the memory 34 and processing in the data format as shown in Fig. 5 attached to the speed limit information for each section managed by the self through the RF module 32 To perform a local broadcast.

As described above, when the vehicle travels on a certain road section in the state where the speed information is locally broadcast in the field apparatus 30 installed in each section according to the characteristics / type of the road (S101), the vehicle apparatus 40 The RF module 42 receives the information of the speed limit for each section which is processed in the data format as shown in FIG. 5 attached to the field apparatus 30 and locally broadcasted and stored in the memory 45 through the main controller 41. (S102).

Subsequently, the main controller 41 in the vehicle device 40 requests the current vehicle speed information from the engine control device / speed measurement device 43 to detect the current traveling speed (S103), and detects the current vehicle speed. It is determined whether or not the current traveling speed exceeds the speed limit for each section in comparison with the speed limit in the section that is recorded and stored in the memory 45 (S104) (S105).

In the above determination, if it is determined that the current traveling speed is in a state of exceeding the speed limit for each section, the main controller 41 in the vehicle device 40 accesses the speed limit voice information from the memory 45 to output the device. Send an alarm sound or voice warning message to decelerate the vehicle speed (44) (S106), counter the elapse of a certain time, and when the elapse of a certain time is confirmed, the engine control device / speed measuring device 43 in real time It is determined whether the current vehicle speed is exceeding the speed limit for each section by comparing with the current vehicle speed detected in step S and the speed limit for each section stored in the memory 45 (S107) (S108) (S109).

If it is determined that the vehicle continues to exceed the speed limit continuously after the warning sound or the voice warning message is sent, the main controller 41 of the vehicle device 40 controls the fuel pump and the injector through the control of the fuel cut-off module 46. By blocking the driving to block the amount of fuel supplied to the engine to reduce the vehicle speed of the running vehicle (S110).

As described above, the current vehicle speed detected in real time by the engine control device / speed measurement device 43 in the decelerated state by the control of the fuel cutoff module 46 and the limit vehicle speed for each section stored in the memory 45 are performed. When it is detected that the comparison is under the speed limit for the corresponding section (S111), the main controller 41 controls the fuel cutoff module 46 to restore the driving of the fuel pump and the injector so that the amount of fuel supplied to the engine is reduced. By maintaining the normal operation of the vehicle is maintained normally (S112) (S113).

If it is determined that the vehicle speed for each section detected in real time from the engine control device / speed measurement device 43 does not exceed the speed limit recorded and stored in the memory 45, the main controller 41 is present. Maintains the vehicle state to maintain normal driving (S114).

As an example, when the vehicle 1 drives ⓐ section in the attached FIG. 4, in the field apparatus (①) installed on the center line / central separator, the speed limit in the section ⓐ is 80Km / h through the data format as shown in FIG. 5. Since the vehicle is broadcasting locally, if the vehicle 1 runs over the speed limit of 80 km / h while driving the section ⓐ, the fuel is cut off and no more speed can be achieved. ), The local device (②) broadcasts the speed limit cancellation in section ⓐ and the speed limit information in section ⓑ, so vehicle 1 has 70 km / h and 80 km / h for section ⓑ. Apply.

Similarly, in the case of vehicle 2 traveling in the opposite direction to vehicle 1, the free section is terminated by the field device (③) and the speed limit 80Km / h for section ⓑ is applied, so the vehicle speed cannot exceed 80Km / h. , Ⓑ Stop the speed limit 80Km / h broadcast from the field device (②) and apply the speed limit 70Km / H to the section ⓐ. do.

As described above, according to the present invention, the vehicle speed is installed for each section according to the characteristics or types of roads, and thus the vehicle speed of the vehicle is automatically adjusted according to the speed limit of the field device, thereby minimizing the occurrence of traffic accidents caused by the driver's speeding. Stable vehicle operation is provided, and stable road traffic traffic is maintained through speed limitations on national roads, urban roads and highways, and speed limitations in accident-prone areas, as well as speed limitations in schools and pedestrian protected areas.
