FIG. 2 is an explanatory diagram of a lane marker system at a merging point according to the first embodiment of the present invention.

In this figure, 100 is a main route (main route), 101 is a merging route, and 102 is a merging zone.
The merging zone 102 is located at a point 1 on the side closer to the traveling direction.
03 and an area sandwiched between points 104 on the far side, and has a length L2. L1 is the distance from the lane marker 1 to the point 103 on the near side. L3 is lane marker 11
Is the distance from the point to the point 103 on the near side. L4 is a distance obtained by correcting the distance between the near point 103 and the far point 104 by the angle in the traveling direction. t0 is the lane marker 1 for measuring the speed of the main route by the vehicle 4 on the main route v1.
, At time t3, the vehicle 14 in the merging path is
It is the time when the vehicle passed the lane marker 11 for speed measurement No. 01.

The lane markers are usually buried on the road surface and are arranged along the traveling path. When the vehicle passes over the lane markers, the information written on the lane markers is transmitted to the vehicles.

Next, the operation of the merging zone lane marker system of the first embodiment will be described.

A lane marker 1 for measuring the vehicle speed is installed in a first zone of the main route 100, and a merging information lane marker 2 is arranged at a distance. When the first vehicle 4 passes over the lane marker 1, speed information is transmitted from the lane marker 1 to the merge information device 30 via the communication line 8. In the merging information device 30, the storage device 20 and the time estimating device 21 calculate and store the time required for the first vehicle 4 to reach the merging zone 102.

On the other hand, a lane marker 11 for measuring the vehicle speed is provided in the second zone of the merging route 101, and a merging information lane marker 12 is arranged at a distance. When the second vehicle 14 passes over the lane marker 11, the speed information is transmitted from the lane marker 11 to the merging information device 30 via the communication line 18.
Sent through. In the merging information device 30, the storage device 2
2. The time estimating device 23 calculates and stores the time to reach the merging zone.

The length of the merging zone 102 in the traveling direction is determined in advance. If no vehicle exists in this range, a collision or the like does not occur at the time of merging, so that merging can be performed smoothly. Vehicle speed is lane marker 1
Alternatively, the measurement is performed as follows at 11, and the result is transmitted to the lane markers 2 and 12 via the communication line 25.

FIG. 3 is an explanatory diagram of lane markers on the main route.

For speed measurement, two lane markers 1a, 1
b is arranged at a predetermined distance, and the speed is measured by measuring the transit time between them. That is, the speed is measured from the time of passing the distance Lm between the first lane marker 1a and the next lane marker 1b, and transmitted to the lane marker 2. 1c is a communication line connecting the lane markers 1a and 1b.

The lane marker 11 for measuring the vehicle speed has the same configuration as the lane marker 1.

FIG. 4 is a diagram in which arrival times at the merging zone of the lane marker system at the merging point according to the first embodiment of the present invention are arranged in chronological order.

In this figure, since the first vehicle has passed the lane marker 1 at time t0, the time t1 at which the first vehicle reaches the near point 103 and the time t2 at which the first vehicle reaches the far side 104 of the merging zone 102 are expressed by the following equations. Is required.

T1 = t0 + L1 / v1 (1) t2 = t0 + (L1 + L2) / v1 (2) Similarly, on the merging path side, time t4 when reaching the point 103 on the near side of the merging zone 102, and point on the far side 104
Is reached at time t5.

T4 = t3 + L3 / v2 (3) t5 = t3 + (L3 + L4) / v2 (4) When the possibility that the vehicle 4 and 14 are mixed in the merging zone 102 is (t5> t2), (t2−t4) > 0 (first condition). When (t2> t5), (t5
−t1)> 0 (second condition). Therefore, t
When the first condition or the second condition is satisfied in the magnitude relationship between 2 and t5, there is a possibility that the vehicles will collide with each other,
Otherwise, the merging determination device 24 can determine that they do not conflict.

The result of this determination is transmitted to the merging information lane markers 2 and 12 of the respective routes via the communication line 25.
This result is obtained when each of the vehicles 4 and 14 has the lane marker 2 or 1
It receives information as it passes over the vehicle 2 and controls the vehicle and calls attention to the driver.

It should be noted that the merging judgment is made when the vehicle entry times t0 and t3 in the first zone and the second zone overlap each other for a predetermined delay time Δt0 or Δt3, respectively. Alternatively, it is configured to automatically prepare for the entry of the next vehicle after the elapse of the time Δt3.

As described above, according to the first embodiment, the merging information is transmitted to the corresponding vehicle by the lane marker, so that the signal is not transmitted to other vehicles, and there is an advantage that the driver is not bothered. . Furthermore, the timing at which each vehicle enters the merging zone from the vehicle speed of the corresponding vehicle is predicted,
Since the notification is not made except when there is a possibility of collision at the junction, there is an advantage that the trouble of the driver can be reduced. Further, since the communication is performed by communication between the vehicle and the lane marker embedded in the road surface, there is an advantage that the radiated electric field can be reduced, and the inconvenience to the inhabitants around the road can be suppressed to a very small extent.

Although the possibility of merging is determined in the first zone of the main route and the second zone of the merging route, the number of zones may be plural. The location of the lane marker 2 or 12 for transmitting the merging information to the vehicle is determined by the merging information device 30 and the information is transferred to the lane marker 2.
Alternatively, the vehicle may be transmitted at a distance of at least the distance that the vehicles 4 and 14 pass through the lane markers 2 and 12 when the lane markers 2 or 12 complete preparation for transmission. Further, the communication with the lane marker or from the lane marker has been described by wire, but it may be wireless. Also,
It is also applicable to intersections such as crossroads.

Next, a second embodiment of the present invention will be described.

FIG. 5 is an explanatory diagram of lane markers on a main route according to a second embodiment of the present invention.

In this figure, reference numeral 1d denotes a lane marker for receiving the speed of the first vehicle 4 from the first vehicle 4. Other parts are the same as in the first embodiment.

Next, the operation of the lane marker on the main route will be described.

In the main route 100, the first vehicle 4 has the transmission antenna system 5, and transmits the vehicle speed from the first vehicle 4 to the lane marker 1d by electromagnetic waves when passing over the lane marker 1d. This lane marker 1d is the lane marker 1 for speed measurement. The lane marker 1d has a receiving device incorporated therein, and has a function of receiving a signal from the first vehicle 4, performing processing such as demodulation, and knowing the speed.

When the speed is determined, it communicates to the merge information device 30. Similarly, in the merging route 101, speed information from the second vehicle 14 on the merging route is communicated to the merging information device 30 by a lane marker having the same function as the lane marker 1d. The subsequent operation is the same as in the first embodiment.

As described above, in the first embodiment, two lane markers are installed at a predetermined distance in order to measure the vehicle speed, and the vehicle speed is measured from the time of passing therethrough. Although it was necessary to dispose them accurately, according to the second embodiment, since the vehicle speed is obtained as information from the vehicle, there is an advantage that measurement can be performed with one lane marker.

Further, the communication line 1c for connecting the two lane markers 1a and 1b is not required, and there is an advantage that the configuration is simplified. In this embodiment, the speed information is obtained from a speedometer of the vehicle.

As described above, in the lane marker 1d, the speed information may be constantly transmitted from the vehicle, or it is determined from the information of the lane marker 1d that the vehicle is the lane marker 1d, and the vehicle operates in the procedure of transmitting the speed information. You may do so. Alternatively, the arrangement may be such that a signal indicating that the next lane marker is the lane marker 1d is sent to the lane marker before the lane marker 1d.
In this case, the transmission time of the vehicle speed information is received, determined,
Since it is shorter than the transmission procedure, there is an advantage that the transmission time while passing through the lane marker 1d can be kept long. That is, it can be an advantageous method for a high-speed vehicle.

Next, a third embodiment of the present invention will be described.

FIG. 6 is a block diagram of a lane marker system at a junction showing a third embodiment of the present invention.

In this figure, reference numeral 40 denotes a merging information device with lateness, and 41 denotes a lateness determining device. Other parts are first
This is the same as the embodiment, and the same reference numeral is given.

Next, the operation of the lane marker system at the merging point according to the third embodiment will be described.

Creating merge information every time a vehicle passes from the main route 100 and the merge route 101 is the same as in the first embodiment. The added functions are as follows.

That is, the first vehicle 4 and the second vehicle 14
A function for determining which of the two arrives at the merging zone 102 first has been added. It is determined which of the two reaches the point 103 on the near side of the merging zone 102 first.
Further, the early or late determination device 41 determines which one passes through the farther location 104 first. The instruction to the vehicle after the determination is performed as shown in FIG. That is, four modes are conceivable depending on the time at which the vehicle reaches the merging zone 102. FIG. 7 shows the merging zone 1
02 only when there is a possibility of contact.

Modes 2 and 4 are completely colliding modes and send a danger signal. At the same time, in mode 2, the first vehicle 4 is instructed to speed up, and the second vehicle 14 is instructed to speed down. It is also possible to instruct the vehicle speed at that time. In the mode 4, the second vehicle 14 is instructed to increase the speed, and the first vehicle 4 is instructed to decrease the speed.

In the mode 1, since there is a possibility of approaching, the first vehicle 4 is instructed to increase the speed and the second vehicle 14 is instructed to decrease the speed. In Mode 3, since there is a possibility of approaching, the second vehicle 14 is instructed to increase the speed, and the first vehicle 4 is instructed to decrease the speed. The two vehicles 4 and 14 receive these instructions from the lane markers 2 and 12, and accelerate or decelerate according to the information.

As described above, according to the third embodiment, the vehicles on the main route merge with the vehicles on the merge route, and the vehicles on the merge route merge with the vehicles on the main route while paying attention. The relative position of the upper vehicle and the vehicle on the merging path in the merging zone is notified to each other, so that a guide for controlling the speed of the vehicle is given, and a safer and smoother merging is possible. There are advantages.

In the third embodiment, a plurality of merging information devices may be provided on the main route or the merging route. For a vehicle that does not follow the instructions, a speed adjustment warning may be sounded on the vehicle side using the current speed and the speed adjustment value.

Next, a fourth embodiment of the present invention will be described.

FIG. 8 is a configuration diagram of a lane marker system at a merging point according to a fourth embodiment of the present invention, in which a plurality of lanes are arranged in parallel.

In this figure, 100 is the first main route,
101 is a merging route, 200 is a second main route, and 201 is a third main route. 4-1 is a vehicle on the second main route 200. 1-1 is a lane marker for speed measurement on the second main route, 2-1 is a lane marker for merging information on the second main route, 1-2 is a lane marker for speed measurement on the third main route, and 2- 2 is a merging information lane marker on the third main route. Each lane marker is connected to the junction information device 50 via a communication line (not shown). Reference numeral 50 denotes a device obtained by expanding the merging information device of the first embodiment so as to correspond to three main routes. Other numbers are the same as in the first embodiment.

Next, the way of merging at the merging path 101 and the first main path 100 in the fourth embodiment is the same as in the first embodiment. In the fourth embodiment, the following functions are added.
Also for the vehicle 4-1 traveling on the second main route 200,
As in the first embodiment, it is configured to determine and notify the possibility of contact and rear-end collision in the merging zone 102.

However, the information content warns the user not to change the lane to the first main route 100 because there is a merging vehicle. Also, the vehicle 4 on the first main route and the vehicle 4-1 on the second main route are running substantially in parallel,
In a situation where the vehicle 14 on the merging route enters, the vehicle 4
Informs the user of the danger of contact at the merging zone 102,
At −1, the fact that the vehicle is entering the merging zone 102 is notified. In addition, the vehicle 4-1 has the vehicle 4 on the first main route.
May be present and may change the runway to the second main route.

Similarly, since the vehicle 4-1 is also present in the vehicle 4, it is informed that changing the running route to the second main route is dangerous. It also has a function of notifying a vehicle (not shown) on the third main route of information on the presence of a vehicle in an adjacent lane.

As described above, according to the fourth embodiment, information corresponding to each vehicle is notified from the lane marker of each lane to the target vehicle on each lane in the merging zone when a plurality of lanes are running in parallel. Since the vehicle can be controlled, it is advantageous that control of each vehicle and work of the driver's attention are given in a suitable form. As a result, there is an advantage that occurrence of an accident at the junction or stagnation of the junction can be reduced.

Although the fourth embodiment has been described with three lanes, any number of lanes may be used.

Next, a fifth embodiment of the present invention will be described.

FIG. 9 is a configuration diagram of a lane marker system at a junction showing a fifth embodiment of the present invention, and FIG. 10 is an explanatory diagram of the operation of the lane marker system at the junction. FIG.
, 60 is a merging information device when the vehicle is traveling vertically in the traveling direction. Other configurations are the same as those of the first embodiment.

The operation of the lane marker system at the junction according to the fifth embodiment is basically the same as that of the first embodiment.
The difference is that a plurality of vehicles (4, 4-
2) is running. This is also a situation setting in which the vehicle 14 exists on the merging path, the vehicles 4 and 14 may come into contact with each other in the merging zone 102 and cause a collision, and the following vehicle 4-2 is running.

At the time t0, the vehicle 4 enters the first zone, and when the vehicle 4-2 enters before the elapse of the time Δt0 (time t0 '), the vehicle 14 on the merging route and the vehicle 4 enter the first zone. The arrival time of the vehicle 4-2 on the near side 103 or on the far side 104 of the vehicle is reduced by the near side 103
In this case, the earlier time is adopted and the farther point 104 adopts the later time [that is, new t1 = earlier (t1, t1).
1 '), new t2 = late (t2, t2')], and the merging information is passed by comparing the arrival times t4 and t5 of the merging route to the merging zone. Furthermore, the lane marker 12 notifies the vehicle 14 that a plurality of vehicles are running. Also, when a plurality of vehicles are traveling on the merging route 101 side, the comparison is performed by the same operation (in this case, new t4 and t5).

As described above, according to the fifth embodiment, there is an advantage that merging can be performed smoothly even when a plurality of vehicles are running vertically. In addition, since it is made clear that the vehicle is still present even after one vehicle passes, it is possible to join with sufficient care, and it is expected that the number of accidents due to inadvertent mistakes by the driver or the like is reduced.

In the above embodiment, two vertically connected vehicles have been described. However, a case where a larger number of vehicles are dependent may be used. Further, it may be combined with the third embodiment described above.

Further, the present invention is not limited to the above-described embodiment, and various modifications are possible based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

[0076]

As described above, according to the present invention, the following effects can be obtained.

(A) Since the merging information is transmitted to the corresponding vehicle by the lane marker, the signal is not transmitted to the other vehicles, and there is an advantage that the driver is not bothered. Furthermore, since the timing at which each vehicle enters the merging zone is predicted based on the vehicle speed of the corresponding vehicle and is not notified unless there is a possibility of collision at the merging point, it is possible to reduce the burden on the driver. There is an advantage. Also,
Since the communication is performed between the vehicle and the lane marker embedded in the road surface, the radiated electric field can be reduced, and the inconvenience to the inhabitants around the road can be minimized.

(B) Since the vehicle speed is obtained as information from the vehicle, there is an advantage that measurement can be performed with one lane marker. Further, there is an advantage that a communication line connecting the two lane markers is not required, and the configuration is simplified.

(C) Vehicles on the main route merge with vehicles on the merge route while vehicles on the merge route merge with vehicles on the main route while paying attention to vehicles on the main route. Since the mutual positional relationship in the merging zone of the vehicles is notified to each other, a measure for controlling the speed of the vehicle is given, and there is an advantage that a safer and smoother merging is possible.

(D) In the merging zone when a plurality of lanes are running in parallel, information corresponding to each vehicle can be notified from the lane marker of each lane to the target vehicle on each lane. There is an advantage that the control of each vehicle and the action on the driver's attention are given in a suitable form. As a result, there is an advantage that occurrence of an accident at the junction or stagnation of the junction can be reduced.

(E) Even when a plurality of vehicles are running vertically, merging can be performed smoothly. In addition, since it is made clear that the vehicle is still present even after one vehicle passes, it is possible to join with sufficient care, and it is expected that the number of accidents due to inadvertent mistakes by the driver or the like is reduced.
