Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a system for preparing a violation evidence when a follower vehicle approaches a preceding vehicle on a road such as a highway and causes a traffic violation due to insufficient holding of an inter-vehicle distance. Regarding

[0002]

2. Description of the Related Art On a highway or the like, in order to prevent an accident such as a rear-end collision due to being too close to each other, the inter-vehicle distance between vehicles traveling back and forth is limited according to the speed of the vehicle. However, there are many accidents due to non-maintenance of the following distance between the following vehicle and the preceding vehicle beyond the limit of the following distance. Currently, police are trying to prevent accidents due to the crackdown, but they have a hard time because there is no means to show evidence of the violation. Up to now, evidence of traffic violations due to insufficient maintenance of inter-vehicle distance is based on numerical values obtained by visual distance measurement by police officers, which is estimated by comparing the distance with the lane markings displayed on the roadway. .

Although it is not possible to accurately measure the distance between vehicles at a stop, it is more difficult to perform the measurement while the vehicle is running, and the measurement error becomes large, and the obtained value is artificial because it lacks objectivity. Considered to be a matter, it cannot be a convincing evidence for a suspect who violates the lack of vehicle distance. Although it is possible to confirm on-the-spot cases of current offenses arrested at the place of violation, it is possible to ensure the effectiveness of traffic crackdown, even if the arrest is later arrested for the violation, the evidence will be ignored or questioned by the suspect. There was a difficult situation.

In addition, the practical work necessary to prevent an accident such as a rear-end collision, that is, a suspect of driving a vehicle shortage of inter-vehicle distance is suspected from a large number of automobiles, and a suspect driving the vehicle is identified and the suspect violates. It was not easy to investigate the history of the vehicle, promptly notify the concerned parties of the vehicle, and contact or call the suspect.

From the longitude and latitude values measured by the GPS longitude / latitude measuring device 2, as shown in the column of the measurement location of the violation Kip K in FIG. 6, the kilometer post of the road position with respect to the longitude and latitude and the address of the location. Is converted by the conversion software installed in the computer 6 and the kilo post and the address of the place are printed out on the violation ticket K. In this case, the measurement mode setting in the simultaneous two-way distance measuring device 1 in the vehicle of the patrol car A is set to the simple mode, and the irradiation point X of the vehicle body of the preceding vehicle C to the irradiation point of the vehicle body of the following vehicle B is set. The inter-vehicle distance L to Y is measured.

In this measuring method, as shown in FIG. 5, the patrol car A is operated in a side-by-side state to the side of the suspicious follower vehicle B, and the distance measuring mechanism 1 mounted on the patrol car A is operated.
5 and a CCD camera mechanism 16 are installed in the two simultaneous bidirectional distance measuring machines (shown in FIG. 2), and the infrared sensor 17 directed right beside the laser irradiation position Z, runs parallel to the patrol car A. At the moment when the body of the follower vehicle B reflects infrared rays or when the reflected state disappears, the switch of the violation evidence creating apparatus S is automatically turned on, or the vehicle running in parallel with the patrol car A (the follower vehicle). B) car
Only when the body is reflecting infrared rays, the manual switch of the violation proof making apparatus S is activated, and the distance measuring device 1
From the laser irradiation position Z to the laser irradiation point Y of the follower vehicle B, and the distance N from the laser irradiation position Z to the laser irradiation point Y of the follower vehicle B.
And are measured at the same time.

Then, the inter-vehicle distance L from the irradiation point X of the preceding vehicle C to the irradiation point Y of the following vehicle B is calculated from the distance and the angle by the triangulation method. The inter-vehicle distance L in this case can be easily calculated by the following calculation formula 2.

[0050]

[Formula 3] Distance of following vehicle: M = 2m Distance of preceding vehicle: N = 23m Angle: When ∠ZYX = 90 N ² = L ² + M ² L ² = N ² −M ² L ² = 23 ² −2 ² L = 22.91m Distance L is 22.91m

[0051]

[Fourth Embodiment] <Distance M to the follower vehicle B in the case of the third embodiment
Is set in advance as a numerical value> The measurement methods of Examples 2 and 3 described above can be further simplified for measurement. The measuring method of Example 3 will be described. In this measurement method, as shown in FIG. 5, the distance from the position Z of the distance measuring machine 1 in one direction of the patrol car A to the laser irradiation point Y of the follower vehicle B is set to a numerical value of, for example, 3 m. Then, in this case, the patrol car A is operated to move toward the side of the follower vehicle B, and from the irradiation position Z of the distance measuring machine 1 in one direction of the patrol car A to the irradiation point Y of the follower vehicle B. At the moment when it is thought that the distance has reached the set value (3 m), measurement is performed by the one-way distance measuring device 1 mounted on the patrol car A.

For example, the set numerical value can be set to a value that makes it easy for a vehicle to approach, such as 2 m, 2.5 m, or 4 m.
The calculation of the inter-vehicle distance L in the case where the luker A is placed in the side-by-side running state of the follower vehicle B can be easily calculated by the following calculation formula 4.

[0053]

[Calculation formula 4] Distance of following vehicle: M = 3m (setting value) Distance of preceding vehicle: N = 22m Angle: When ∠ZYX = 90 N ² = L ² + M ² L ² = N ² −M ² L ² = 22 ² -3 ² L = 21.79m The distance L between vehicles is 21.79m.

In the case of the calculation formula 4, the set distance is 3 m, but when the distance when actually approaching is 3.2 m, the calculation is as shown in the following calculation formula 5.

[0055]

[Calculation formula 5] Distance of following vehicle: M = 3.2 m (actual distance) (Distance of following vehicle: M = 3.0 m (set value)) Distance of preceding vehicle: N = 22 m Angle: ∠ZYX = 90 If N ² = L ² + M ² L ² = N ² −M ² L ² = 22 ² −3.2 ² L = 21.76m The inter-vehicle distance L is 21.76m.

Therefore, this calculation formula 5 and the above calculation formula 4
21.79m-21.76m = 0.03m, and if the set value is 3m and the actual approach distance differs from the set value by 20cm, the inter-vehicle distance L will be approximately within 3cm. Can be measured. The magnitude of this error depends on the patrol car driving skill of the police officer, but normally there is a skill of about ± 0.20 cm with respect to the set value of 3 m, so there is a gap even more than that. Also, the measurement of the inter-vehicle distance L can obtain a numerical value within an error range within about 10 cm. Although this measured numerical value is an approximate value, it is an extremely accurate numerical value that cannot be obtained by the conventional visual measurement.

When the irradiation position Z of the one-way distance measuring machine 1 is measured in such a position that the vehicle registration number plate of the follower vehicle B cannot be seen, a CC image is simultaneously panoramic photographed.
Since the vehicle registration number plate of the chasing person B is not shown in the camera image of the D camera 8, it may be difficult to identify the suspected person. In this case, the vehicle registration number plate is moved to a position where the suspected person can be photographed. Then, the image can be used as supplementary evidence for confirmation of the suspected vehicle.

[0058]

The present invention is as described above, and a mechanically accurate distance can be measured from the vehicle of the patrol car A while it is running by the violation evidence preparation device S, and the distance to the car running in parallel with the patrol car A can be measured. Even with a simple measurement method with numerical values set, the distance L between
Can be measured. Therefore, the persuasive power of the traffic violation to the suspect is greatly improved.

Further, in the case of the form provided with the CCD camera mechanism 16 for taking a photograph of the laser irradiation point marked on the distance measuring machine 1 instead of the ambiguous visual measurement, the measuring point of the traveling vehicle is measured. Since it became clear and a higher level of evidence of customer-friendliness was obtained by mechanical measurement, it became possible to be adopted as evidence of a violation of insufficient keeping of inter-vehicle distance in litigation. In particular, in the case where the CCD camera 8 capable of panoramic image capturing that operates simultaneously at the time of measurement is used, the camera image of the violation scene becomes an evidence photograph, and by attaching this to the violation ticket K, it is possible to prevent the suspect from escaping. It became so.

Further, the violation management data managed by the vehicle registration number based on the data of the created violation ticket K is created, and the management data is stored in the vehicle of the patrol car A at the violation site. By making it possible to exchange the sub-computer system 11 and the main computer system 12 of the headquarters via the communication lines 13 and 14, it is possible to swiftly manage and use the evidence information of the violation to every corner of the country. Since it is possible to do this, it is possible to easily search for perpetrators and people requiring attention from the management data of that information, so that quick attention and warning can be given and accidents such as rear-end collisions can be prevented. Yes, traffic control will be effective.
