Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic safety support device, and more particularly to a traffic safety support device when it is determined that a danger event is highly likely to occur based on a driving situation received by a detection device installed on a road network. In addition, the present invention relates to a traffic safety support device for notifying warning information to the vehicle.

[0002]

2. Description of the Related Art At intersections where there is no traffic light, curves with poor visibility, and the like, encounter accidents are likely to occur because the vehicle does not stop or does not sufficiently decelerate. The main causes of such accidents are driver's carelessness, such as overlooking a stop sign or protruding from the center line of a curve. However, the occurrence of mistakes in human behavior is reduced to 0%. It is impossible. In order to reduce traffic accidents on such a premise, it is effective to call a driver's attention at a dangerous point. However, measures that have conventionally been taken to draw the driver's attention include, for example, making a temporary stop sign by blinking a lamp at night or blinking a center line of a curve. If you are used to a road that you are used to, such as a commuting road, the effect of the habituation is often reduced, and the effect of the alert was not so expected.

[0003] Further, the "accident prevention traffic control system" disclosed in Japanese Patent Application Laid-Open No. 10-302200 detects the speed of a vehicle on an inflow channel on a non-priority side of an intersection, and when the speed exceeds an appropriate speed, priority is given to the vehicle. This is to notify the warning information to the vehicles flowing into the inflow path on both the side and the non-priority side. However, in this system, only the passing speed at a certain point is considered, and acceleration / deceleration is not taken into account. Therefore, when the speed is equal to or more than a certain value, a warning is issued. Therefore, during acceleration / deceleration, an unnecessary warning is issued when it is actually possible to stop, and even if it is dangerous to induce sudden braking and it is determined that it is safe, it is actually accelerating. It may be dangerous. In addition, only applicable intersections are mentioned.
Further, in the configuration of the known example, the system is a single system installed and operated at one intersection, for example, to monitor the actual operation status, such as simultaneously monitoring the operation status of the devices installed at multiple intersections, and to evaluate the effect. Secondary effects such as evaluation cannot be obtained.

In order to avoid duplication of description, the first to third embodiments will be described.
Will be described collectively.

The points applicable to the configuration of the present apparatus include: (1) a point where traffic is restricted such as a temporary stop, (2) a point where a head-on collision is likely to occur, and (3) an oncoming vehicle which has poor visibility such as a curve. Since there can be assumed three cases, that is, a point at which there is a risk of collision, the following description will be made assuming these three application examples. 4 to 6 show examples of the shape of each application point.
Shown in

The traveling state detecting means 1 (a... N) is installed in front of a point where danger situations are likely to occur, for which warning information needs to be issued, and detects traveling conditions of the vehicle such as speed. Since a time delay such as communication time and calculation processing time is required between the speed detection by this means and the notification of the warning information, the distance from the point where the vehicle needs to be stopped is also taken into consideration, taking into account the vehicle passing time. Take enough.

For example, it is assumed that the time required from the detection of the speed to the issuance of the warning information takes 4 seconds, and the passing speed of the vehicle is reduced to 6 seconds.
Assuming 0 km / h, 60 × 1000/3600 × 4 = 66.7m is required.

Further, as for the place where the present apparatus is installed, an arbitrary number of the means may be installed in accordance with characteristics such as traffic regulation, shape, number of inflow paths and the like at the point to which the present apparatus is applied. For example, when the present invention is applied to a point where stoppage is restricted, reference numeral 42 shown in FIG. 4 is a traveling state detecting means, which is installed at one place before the stop line as shown in the figure. In the case where the present invention is applied to a point where a head-on collision is likely to occur, 52, 53, 54, and 55 shown in FIG.
Installed before each intersection inflow section of each inflow channel where there is a risk of crossing into the intersection. In this case, since the number of inflow channels is 4, the number is four. In addition, when the present invention is applied to a place such as a curve where visibility is poor and there is a risk of collision with an oncoming vehicle, 62 and 63 shown in FIG. Installed before the inflow channel.

Further, if the present means does not use the means for measuring the point speed, but uses an image sensor or the like, it is possible to detect not only the speed at the passing point but also the speed history until passing.

The warning information control means 2 is placed on the road as a controller of a point where the warning information needs to be provided, and selects or prepares warning information to be provided to the vehicle based on the information from the driving situation detecting means 1. This is a means for transmitting information to the warning information notifying means 3. Hereinafter, the means 21 to 27 will be described in more detail.

The vehicle approach information recognizing means 21 is means for receiving the detected vehicle speed information and transmitting necessary information to the vehicle condition predicting means 22. Also, when the present invention is used not for warning against stoppage regulation, but for use in preventing vehicle-to-vehicle collisions such as an encounter accident, a collision accident at a curve,
Since the traveling state detecting means 1 is installed at a plurality of locations,
The information is transmitted together with identification information indicating which traveling state detecting means the information is.

The vehicle condition predicting means 22 predicts a vehicle condition at a point where a danger situation may occur (hereinafter referred to as a target point) from the vehicle approach information received by the vehicle approach information recognizing means 21. It is. This is a means for calculating a time of arrival at a target point and a predicted value of the speed from a traveling state such as a speed at the time of reception of the inflow path where the vehicle approach information is received.

For example, the case where the present invention is applied to an intersection with a stop restriction will be described with reference to FIG. 4. The target point is a stop line indicated by 41, and the predicted driving condition is the speed at the target point. The speed detected by the driving condition detecting means 42
Assuming that the vehicle runs at a constant speed at V, the speed at the target point is also V.

The case where the present invention is applied to a point where a head-to-head collision is likely to occur will be described with reference to FIG. 5. The target point is within an intersection indicated by 51, and the predicted driving situation is the arrival time at the target point. It is. The calculation method is 52 to 55
When the time when the vehicle is detected by any of the traveling condition detecting means is T1, the speed is V1, and the distance from the traveling condition detecting means to the target point is d1

[0031]

## EQU1 ## t1 = d1 / v1 + T1.

In addition, the present invention has poor visibility such as a curve,
Referring to FIG. 6, a case where the vehicle is applied to a place where there is a danger of a collision with an oncoming vehicle is described. Arrival time to Equation 1 is similarly used for the calculation method.

Next, the regulation information storage means 23 will be described. This is achieved by storing the data corresponding to the driving situation detecting means 1 installed in the traffic-controlled inflow path and the warning information notifying means 3, and using the driving situation predicting means 22 detected by the driving situation detecting means 1. When the driving situation is predicted to be dangerous, the information is used to identify which warning information notifying means should transmit the warning information.

In the example of FIG. 4, the suspension regulation is assigned to the traveling state detecting means 42, and when it is determined that the driving is dangerous, the warning information is provided to the warning information notifying means 43. it can.

Next, the driving condition detecting means / warning information notifying means installation information storing means 24 will be described. The information stored in this means stores the installation position information of the traveling information detecting means and the warning information notifying means, which are devices installed on the road, and creates warning information by the warning information creating means 26. In this case, it is a means for storing information for coping with an inflow port having a risk of collision, intersection, or the like. Specifically, (1) which inflow channel each traveling condition detecting means 1 and warning information notifying means 3 installed on the road are installed at what position from the target point, and (2) which This is a means for storing information such as which warning information notifying means the running situation detecting means corresponds to, and (3) a combination of inlets and outlets that need to determine the risk of collision and crossover.

Are shown below.

The danger judgment criterion storage means 25 stores the danger criterion for judging whether or not the situation at the target point predicted by the driving situation prediction means 22 is dangerous. This is means for storing in advance according to conditions such as the shape. FIG. 8 shows an example of a risk determination criterion for each application point.

The warning information creating means 26 calculates the risk based on the predicted driving condition from the driving condition predicted by the driving condition predicting device 22 and the risk criterion stored in the risk criterion storing means 25 as a reference value. This is a means for creating warning information when it is determined that the above is true.

This means is for selecting warning information to be provided from the danger standard and the predicted traffic situation. FIG. 9 shows an example of the type of warning information to be provided. In the case of this embodiment, it is assumed that the determination is made in two ways, that is, the risk reference value is equal to or greater than the risk reference value. The type of warning information may be stored in the storage unit, and the type of warning information may be prepared for each stage and used properly.

The warning information transmitting means 27 reads the warning information created by the warning information creating means 26 while referring to the traveling state detecting means / warning information notifying means installation information storing means 24.
These are means for transmitting to the corresponding warning information notifying means 3.

The process 102 is a process for calculating a predicted value of the traveling state at the target point of the inlet i. Specifically, the arrival time at the intersection, which is the target point, is calculated using Equation 1. The process 103 is a process for determining whether or not the processes for all the inlets have been completed.

The process 104 is a process for incrementing the number of the target inlet when the process for all the inlets is not completed in the process 103.

In step 105, when it is determined in step 103 that the processing for all the inlets is completed, the number of the inlet i to be processed is initialized to 0.

The process 106 is a process for determining the degree of risk of the inlet i. Specifically, the difference between the inlet i and the arrival time at the target point of the inflow channel intersecting with the inflow channel is determined.

The process 107 is a process for determining whether or not the risk calculated in the process 106 is equal to or larger than the reference value by referring to the risk determination criterion storage means.
