Hereinafter, for convenience of description, the forward vehicle information providing system 10 will be abbreviated as the forward prediction system 10 and will be described later.

The forward prediction system 10 includes an information collection unit 100 , a base station 200 , a server 300 , and a user terminal 400 .

The information collection unit 100 collects vehicle traffic information. The information collection unit 100 includes a vehicle detection sensor 110 (VDS, Vehicle Detection Sensor).

In an embodiment of the present invention, a plurality of vehicle detection sensors 110 may be provided. For convenience of description, three vehicle detection sensors 111 , 112 , and 113 are shown in FIGS. 1 and 2 .

A plurality of vehicle detection sensors (111, 112, 113) may be installed on the road so as to be spaced apart from the adjacent vehicle detection sensors (111, 112, 113) and a predetermined distance. In a preferred embodiment, the predetermined interval may have a range of 1 km or more and 2 km or less. However, the present invention is not limited thereto, and the predetermined interval may be arbitrarily set in consideration of geographic features, traffic conditions, and other environmental factors. For example, the predetermined interval may have a smaller value on a downhill road than on an uphill road, and may have a smaller value on a road with a large amount of vehicle movement than on a road with a small amount of vehicle movement.

The vehicle detection sensors (111, 112, 113) measure the traffic information of the vehicle passing through each of the vehicle detection sensors (111, 112, 113). The traffic information may be number and speed information of vehicles. Accordingly, the number and speed information of the front vehicle FC moving ahead of the driving vehicle UC defined as the vehicle in which the user is traveling can be measured by the vehicle detection sensors 111 , 112 , and 113 . . The speed information of the front vehicle FC measured from the vehicle detection sensors 111 , 112 , and 113 is defined as front speed information.

In this embodiment, the vehicle detection sensors (111, 112, 113) may be a pressure sensor. Specifically, the vehicle detection sensors (111, 112, 113), including the tube installed on the road surface on the road, by measuring the pressure change in the tube when the vehicle passes through the tube, the number and speed information of the vehicle can be measured. have. In another embodiment of the present invention, the vehicle detection sensors (111, 112, 113) may be a loop detector. In this case, the vehicle detection sensors 111 , 112 , and 113 may include a loop coil buried in a road, and measure the number of vehicles and speed information by measuring a change in inductance when the vehicle passes. In addition, the vehicle detection sensor (111, 112, 113) may be any one of a magnetic detector, an image detector, AVI, CCTV, microwave detector, infrared detector.

The information collection unit 100 according to an embodiment of the present invention collects traffic information. The information collection unit 100 may collect the traffic information measured from the vehicle detection sensors 111 , 112 , and 113 by grouping them by item, such as by vehicle type, by lane, or by location of the vehicle detection sensors.

The information collection unit 100 according to an embodiment of the present invention may further include a user sensor 120 . The user sensor 120 measures the speed of the driving vehicle UC. According to an embodiment of the present invention, the user sensor 120 may be provided in the form of vehicle detection sensors (VDS, 120a, 120b). That is, the vehicle detection sensors 120a and 120b may serve as user sensors for measuring the speed of the driving vehicle UC. In addition, in another embodiment of the present invention, the user sensor 120 may be provided in the form of a GPS sensor and mounted on the user terminal 400 . That is, the user terminal 400 may include a GPS module.

In another embodiment of the present invention, the information collection unit 100 may not measure the user speed. That is, the information collection unit 100 may not include the user sensor 120 .

The base station 200 receives traffic information from the information collection unit 100 and provides it to the server 300 . In addition, the base station 200 may receive the safety speed information from the server 300 and provide it to the user terminal 400 .

Exemplarily, the base station 200 includes a first base station 210 and a second base station 220 . The first base station 210 receives the traffic information of the front vehicles (FC) passing through the vehicle detection sensors (111, 112, 113) from the vehicle detection sensors (111, 112, 113) to the server (300) send. The second base station 220 receives the speed information of the driving vehicle UC from the user sensor 120 and transmits it to the server 300 . In addition, the second base station 220 may receive the safety speed information from the server 300 and provide it to the user terminal 400 . This has been described as an exemplary embodiment, and the present invention is not particularly limited to the number or shape of the base station 200 .

The server 300 includes an arithmetic processing unit 310 and a control unit 320 .

The calculation processing unit 310 generates safe speed information based on the forward speed information. The safety speed information may be updated every predetermined time. That is, the operation processing unit 310 may regenerate the safety speed information at predetermined time intervals.

The safe speed information includes at least one of a forward speed value defined as a representative value of the forward speed information or a comparison value obtained by comparing the forward speed value with the speed of the traveling vehicle.

In order to generate the forward speed value, first, the calculation processing unit 310 generates a forward speed information group by selecting only a part of the traffic information group collected from the information collection unit 100 , that is, the forward speed information.

The forward speed information group according to the present embodiment may be forward speed information measured from at least one vehicle detection sensor spaced apart within a predetermined distance range from a driving vehicle defined as a vehicle driven by the user. In the present invention, the predetermined distance is not particularly limited, and the predetermined distance may be arbitrarily set when designing a system.

The criteria for selecting the forward speed information group may vary. The forward speed information group according to an embodiment of the present invention may include speed information for each position of a specific front vehicle. Specifically, the calculation processing unit 310 may generate a front speed information group by selectively grouping only the front speed information of some front vehicles among the plurality of front vehicles passing through the vehicle detection sensors 111 , 112 , 113 . .

The forward speed information group according to another embodiment may include speed information of front vehicles measured from a specific vehicle detection sensor. Specifically, the calculation processing unit 310 selects at least some of the plurality of vehicle detection sensors 111, 112, and 113 and groups only the forward speed information of vehicles passing through the corresponding vehicle detection sensors 111, 112, and 113. Thus, a forward speed information group can be generated.

The forward speed information group according to another embodiment may include speed information of vehicles in front passing through a specific lane. For example, the calculation processing unit 310 may generate a forward speed information group by grouping only the forward speeds of vehicles passing through the bus-only lane. In addition, the calculation processing unit 310 may generate a forward speed information group for each lane, respectively.

The criterion for selecting the forward speed information group of the present invention is not limited to the above-described embodiment.

In the present invention, the representative value of the forward speed information, that is, the forward speed value may be calculated by a specific operation. For example, the forward speed value may be defined as the lowest value among the forward speed information constituting the forward speed information group. In addition, the forward speed value according to another embodiment may be defined as an average value of the forward speed information constituting the forward speed information group. The present invention is not particularly limited to the type of calculation of the forward speed value.

In this embodiment, the above-described comparison value means the difference between the user speed value defined as the speed of the traveling vehicle and the front speed value. As the size of the comparison value increases, the speed difference between the front and rear vehicle groups may increase, which may cause an accident. In another embodiment of the present invention, when the information collection unit 100 does not include the user sensor 120, the comparison value is not generated.

The control unit 320 reprocesses the safety speed information provided from the operation processing unit 310 . Specifically, the control unit 320 generates a plurality of modes based on the safe speed information.

When the information collection unit 100 includes the user sensor 120 , a plurality of modes may be distinguished according to the size of the comparison value. A method of distinguishing a mode according to the magnitude of the comparison value will be described in more detail below with reference to FIG. 5 .

On the other hand, when the information collection unit 100 does not include the user sensor 120, the comparison value is not generated, so the safe speed information includes only the forward speed value, and a plurality of modes are distinguished according to the size of the forward speed value. can be For example, the plurality of modes may include a safe mode, a caution mode, and a warning mode. The safe mode is a case in which the forward speed value is larger than the preset speed specific speed reference value section. That is, in the safe mode, the speed of the forward vehicle (FC, FIG. 1 ) moving forward is relatively fast, which means that the front traffic situation is smooth. The attention mode is a case in which the forward speed value is within the specific speed reference value section, and since the speed of the front vehicle FC (FIG. 1) moving forward has decreased, it means that the front vehicles are moving slowly. In addition, the warning mode is a case in which the forward speed value is smaller than the specific speed reference value section, and since the speed of the vehicle in front (FC, FIG. 1 ) is relatively small, it means that there is a congestion in the front.

The user terminal 400 is mounted on the driving vehicle UC. The user terminal 400 displays the modes generated by the control unit 320 . That is, the user terminal 400 may display safety speed information through an image. In this case, although not shown in the drawings, the user terminal 400 may include a display module (not shown).

In addition to the above-described embodiment, according to another embodiment of the present invention, the user terminal 400 may provide the modes generated by the controller 320 to the user in various ways. The user terminal 400 includes at least one module for delivering a plurality of modes to a user. For example, the user terminal 400 may include a speaker or a haptic device. In this case, the user may be provided with sound effects, vibrations, and the like from the user terminal.

In addition to this, the user terminal 400 may further include a GPS module for measuring user speed, a wireless communication module for wireless communication with a base station, a navigation module, or an input module for inputting a user's command.

The forward prediction system 10 according to an embodiment of the present invention can reduce the possibility of a traffic accident and alleviate vehicle congestion by providing the user with safe speed information about the vehicle in front moving forward.

3 is a flowchart of a method for providing front vehicle information according to an embodiment of the present invention.

Referring to FIG. 3 , the method for providing front vehicle information according to an embodiment of the present invention includes a step of collecting front speed information (S1), a step of generating safe speed information (S2), and a user terminal 400 (FIG. 2). and displaying safe speed information (S3).

Specifically, first, forward speed information of the front vehicles FC traveling in front of the driving vehicle UC ( FIG. 1 ) is measured and collected ( S1 ). The forward speed information may be grouped and collected by item, such as by vehicle type, by lane, or by location of the vehicle detection sensors (111, 112, 113, FIG. 1) according to arbitrarily.

Thereafter, safety speed information is generated based on the forward speed information (S2). The safe speed information may include a forward speed value and a comparison value calculated therefrom, and the forward speed value may be a representative value of a plurality of forward speed information constituting an arbitrarily selected forward speed information group. The criteria for selecting the forward speed information group may be various as described above. The comparison value is defined as the difference between the user speed value defined as the speed of the driving vehicle (UC, FIG. 1 ) and the front speed value.

The generated safe speed information is provided to the user terminal 400 (FIG. 2) (S3). The method for providing the safe speed information is not particularly limited, but preferably, the user terminal 400 ( FIG. 2 ) includes a display module (not shown), and the safe speed information may be provided to the user through an image.

4 is a flowchart of a method for providing front vehicle information in which a step of generating safe speed information is specifically illustrated.

As shown in Fig. 4, the information collection unit 100 (Fig. 2) collects forward speed information (S10), and the calculation processing unit 310 (Fig. 2) of the server 300 (Fig. 2) generates a forward speed value (S20). ), the user sensor 120 (FIG. 2) receives the user speed (S30). In this embodiment, the step (S20) of generating the forward speed value (S20) does not need to precede the step (S30) of receiving the user speed.

Thereafter, the calculation processing unit 310 ( FIG. 2 ) compares the forward speed value and the user speed value to generate a comparison value ( S40 ), and the generated comparison value may be provided to the user terminal 400 ( FIG. 2 ) ( S50 ). ).

5 is a diagram illustrating an example of a method of displaying a comparison value shown in FIG. 4 , and FIGS. 6A to 6B are diagrams illustrating an example of a display screen of a driver's terminal. 6A to 6B are exemplarily illustrated only when the safety speed information is provided to the user terminal 400 ( FIG. 2 ) in the form of an image for convenience of explanation.

Referring to FIGS. 5, 6A and 6B , a comparison value is divided into a plurality of modes by the controller 320 ( FIG. 2 ) and provided to the user terminal 400 ( FIG. 2 ). The plurality of modes may include a safety mode (S50a), a caution mode (S50b), and a warning mode (S50c).

The safe mode (S50a), the caution mode (S50b), and the warning mode (S50c) may be displayed on the user terminal 400 ( FIG. 2 ) by being distinguished by a font size, a color, and the like. 6A and 6B, the forward speed is displayed without a color change in the safety mode (S50a), the forward speed is displayed in yellow letters in the caution mode (S50b), and the forward speed is displayed in the warning mode (S50c) In the case of , an example in which the forward speed is displayed in red letters is shown.

The above-described example is limited to the case in which the user terminal 400 ( FIG. 2 ) includes a display module. In another embodiment, when the user terminal 400 (FIG. 2) includes a haptic module, the safety mode (S50a), the attention mode (S50b), and the warning mode (S50c) are distinguished by the type and intensity of vibration, and the like. It may be provided to the terminal 400 ( FIG. 2 ).

The safety mode S50a, the caution mode S50b, and the warning mode S50c may be distinguished by comparing the magnitude of the comparison value with a preset caution reference value and a warning reference value. As described above, the magnitude of the comparison value means the difference between the user speed value and the forward speed value.

The caution reference value and warning reference value can be arbitrarily set in consideration of geographic characteristics, traffic conditions, and other environmental factors. For example, in FIGS. 6A and 6B , a case where the attention reference value is 30 km/h and the warning reference value is 50 km/h is illustrated.

When the comparison value has a value smaller than the preset attention reference value, the state of the safe mode S50a is displayed on the display screen of the user terminal 400 ( FIG. 2 ). For example, when the current speed is 50 km/h and the forward speed value is 40 km, the comparison value is 10 km/h, so it has a value smaller than the attention reference value of 30 km/h.

When the comparison value has a value greater than the preset attention reference value and less than the warning reference value, the state of the attention mode S50b is displayed on the display screen of the user terminal 400 ( FIG. 2 ). For example, when the current speed is 80 km/h and the forward speed value is 40 km/h, the comparison value is 40 km/h, so it is greater than the caution reference value of 30 km/h and less than the warning reference value of 50 km/h.

When the comparison value has a value greater than the preset warning reference value, the state of the warning mode S50c is displayed on the display screen of the user terminal 400 ( FIG. 2 ). For example, when the current speed is 100 km/h and the forward speed value is 40 km/h, the comparison value is 60 km/h, which is greater than the warning reference value of 50 km/h.

As described above, the forward prediction system 10 ( FIG. 2 ) according to an embodiment of the present invention measures information of the front vehicle (FC, FIG. 1 ) and transmits safe speed information to the user terminal 400 ( FIG. 2 ) in a plurality of By providing modes, the user can predict the traffic situation ahead. Therefore, according to an embodiment of the present invention, it is possible to reduce the possibility of a traffic accident by reducing the speed difference with the vehicle group in front, and to alleviate the congestion phenomenon.
