BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic support program and a traffic support device for acquiring information about surrounding objects.

[0002]

2. Description of the Related Art Conventionally, in road traffic, visual recognition is used to recognize surrounding objects. Moreover, in order to identify one's current position, he relied on information such as signs and scenery.

However, at night or in bad weather, the visual ability deteriorates, which impairs safety. Therefore,
In order to assist visual recognition at night, for example, a reflector is installed on a guard rail or the like. However, this method cannot exert its effect unless it is illuminated by a headlight, and cannot be recognized because the light does not reach in bad weather.

Further, radar devices are also installed in automobiles and the like. The radar device receives a radio wave or light that is reflected back by a surrounding object and measures the distance to the object from the round-trip time difference. However, the resolution of the radar device is significantly inferior to that of visual observation, and it is difficult to discriminate when multiple objects are present close to each other, and small objects may be overlooked. It is not possible to identify the or the individual.

As described above, the recognition of surrounding objects is very dependent on the visual sense, which is one of the causes of fatigue in road traffic.

Further, in a city area and the like, there are many surrounding objects on the road, which often hinders recognition of necessary objects such as road signs. In order to solve these problems, the present invention integrates a function of recognizing the presence of a surrounding object with a radar and a function of communicating and acquiring information of the surrounding object, and at the same time, a partner side or a traveling road. Install a transponder type communication device near each other to communicate information with each other, and in addition to recognizing surrounding objects, obtain information from the other party or accumulated information (information such as running information, weather information, bulletin board information) and warn The purpose is to ensure safety in traffic by using it for control.

Further, the transponder type communication device 3 is arranged at one or a plurality of points at the points where the traveling paths of the vehicles intersect or immediately before, and receives the signal transmitted from the vehicle traveling from a certain direction, and When a signal transmitted from another vehicle traveling in another direction intersecting with the direction is received, the information is returned to each vehicle.

At this time, the information is information relating to a vehicle collision at the head of the vehicle. Therefore, in addition to the function of recognizing the existence of surrounding objects by the radar, the integrated function of communicating and acquiring the information of the surrounding objects is provided, and the transponder communication device 3 is arranged near the partner side or the traveling path.

FIG. 2 shows an example in which the front vehicle is equipped with a transponder type communication device 3 at the rear part thereof, a brake sensor is used as a sensor, and information such as acceleration / deceleration information during tandem traveling is shared as information.

In the case of the rear vehicle, an example is shown in which the radar integrated communication device 2 is attached to the front part, brake control is performed as a control, and a danger alarm is displayed as a display. Next, the operation of the configuration of FIG. 2 will be described in detail with reference to FIGS.

FIG. 3 is a flowchart (No. 1) for explaining the operation of the present invention. Here, the front vehicle and the rear vehicle correspond to the front vehicle and the rear vehicle in FIG. 2, respectively. In FIG. 3, in S1,
Detect radar waves. This is because the transponder type communication device 3 attached to the rear part of the front vehicle detects the radar wave transmitted from the radar integrated communication device 2 attached to the front part of the rear vehicle.

At S2, a departure instruction is given. This is because in S1, the front vehicle receives the radar wave from the rear vehicle and is ready to travel in tandem, so the departure instruction is transmitted to the rear vehicle. S3
Then, send the indicated speed. The speed at which the front vehicle travels (instructed speed) is transmitted to the rear vehicle.

In S4, it is determined whether or not to give a stop instruction. This is to determine whether or not the destination is stopped or there is an obstacle. If YES, a stop instruction is provided in the rear vehicle and transmitted in S5. If NO, S
Repeat 3.

As described above, when the front vehicle (with the transponder mounted at the rear) detects the radar wave from the rear vehicle and knows that the rear vehicle is ready for tandem traveling, it sends a departure instruction,
It becomes possible to travel by transmitting the instruction speed, transmit a stop instruction when reaching the destination or find an obstacle, and sequentially transmit information to the rear vehicle to travel in tandem with the rear vehicle.

On the other hand, in S11, the rear vehicle notifies the front vehicle that it is ready for tandem running by emitting radar from the transponder type communication device 3 attached to the front portion. S12
Then, the signal from the preceding vehicle is received.

In the subsequent steps, the radar range finding steps of S13 to S15 and the received information processing steps of S16 to S19 are performed in parallel. In S13, S
Radar distance measurement is performed based on the signal received at 12. this is,

At S16, information is extracted from the signal received at S12. In S17, it is determined whether the information extracted in S16 is stopped. In the case of YES, the information is found to be the stop instruction in S18, so the operation is stopped (the brake is applied to stop). On the other hand, in the case of NO, since speed control was found in S19, speed control is performed to the instructed speed (speed control is performed by controlling the accelerator or brake actuator).

As described above, the rear vehicle (the radar integrated communication device 2 is mounted on the front portion) detects the transmission signal from the front vehicle and receives the departure instruction, the speed instruction, and the stop instruction transmitted from the front vehicle, It becomes possible to obtain tandem driving safely by acquiring vehicle information.

In FIG. 4, in S30, the rear vehicle emits a radar wave toward the front vehicle. In S31, a radar wave is received from the preceding vehicle. In the subsequent steps, the steps of radar ranging from S37 to S39 and the steps of processing the received information from S32 to S36 are performed in parallel.

In S32, information is extracted. This is S3
The information transmitted from the preceding vehicle is extracted from the radar wave received in 1. The determination is made in S33.

If it is determined in S34 that the brake instruction is issued in S33, the brake is applied. In S35,
Depending on the determination in S33, a warning to the driver (for example, a warning indicating that there is an obstacle in front of the front vehicle) is displayed or voiced.

If it is found in S36 that the other information is obtained by the determination in S33, the corresponding other information is displayed or appropriate control is performed. In S37, radar distance measurement is performed.
This is obtained by calculating the distance to the preceding vehicle based on the time difference between the transmitted radar wave and the received radar wave.

In S38, it is determined whether the vehicle is too close. Yes
In this case, the brake control (controlling the actuator to apply the brake) is performed in S39. Based on the above, the rear vehicle will perform braking, warning to the driver that there is an obstacle etc. and other relevant control based on the information transmitted from the front vehicle, and automatically when it gets too close to the front vehicle. It becomes possible to apply the brakes.
