FIG. 1 is a diagram for explaining an outline of a vehicle traffic system 100 to which the present invention is applied. The vehicle traffic system 100 includes a traveling track R that constitutes a shuttle-type closing system, a vehicle TR that shuttles on the track R, and general operations such as shuttle traveling and security control of the vehicle TR on the track R. A control system (including each step and each means constituting the present invention) 1 for controlling.

The traveling orbit R has two turning points P1a.
(The left side in the example in the figure) and a main line (single line portion) R composed of a single line connecting between P1b (the right side in the example in the figure)
1, two branch points P2a on the main line R1 (the left one in the example in the figure) and P2b (the right one in the example in the figure)
It is composed of a passing part R2 composed of two branch lines (hereinafter, the upper one is referred to as “A line” and the lower one is referred to as “B line” in the example in the figure) connecting between them.

The vehicle TR is composed of two trains (hereinafter referred to as "form 1" for convenience) forming a pair capable of shuttle traveling in opposite directions from the main line R1 on both sides of the passing portion R2 via the passing portion R2. "Knitting 2"). In this example, each vehicle platoon has two vehicles (for example, about 10 m in length) mechanically connected to each other via a connecting portion (for example, about 1 m in length).
(About 1 m). The traveling speed of the vehicle TR is
For example, the maximum is set to [30 km / h].

The control system 1 includes a vehicle-side device 10 mounted on the vehicle TR and a plurality of loop antennas for a road-to-vehicle communication antenna (signal device) laid at a predetermined location on the traveling track R (described later). 1C, 2C, AC, BC, A1
C, A2C, B1C, B2C), and a ground-side device 20 capable of bidirectionally communicating information with a vehicle via each of these loop antennas.

Each of the loop antennas is provided with a departure / stop loop antenna 1C and 2C of the vehicle TR disposed at the turning point 1a or 1b on the main line R1, and with the A of the passing portion R2.
Loop antennas AC and BC for stopping at the time of vehicle erroneous entry (for protection against entry into a different line) arranged on the line and the line B
And loop antennas A1C and A2C and B1C and B2C for a collision protection section (closed section) arranged on lines A and B on the passing portion R2. The total length of each loop antenna is the distance required for the vehicle TR to stop from the maximum speed (for example, the maximum speed [30 km / h]).
And a margin (for example, about 12 m) added to a deceleration of 0.2 [G] for about 18 m.
It is set to about 0 m.

The vehicle-side device 10 is a vehicle-side control device 11 which is responsible for a vehicle-side control center such as a traveling / stop control of the vehicle TR.
A road-to-vehicle communication device 12 including a road-to-vehicle communication antenna capable of road-to-vehicle communication with the ground-side device 20 via each loop antenna; and a vehicle-to-vehicle communication antenna that allows vehicles to communicate wirelessly. And a vehicle-to-vehicle communication device 13.

The vehicle-side control device 11 includes, for example, a computer. In this example, when the vehicle-side control device 11 is on the loop antenna, the vehicle-side control device 11 detects the presence of the vehicle TR via the loop antenna via the road-vehicle communication device 12. In addition to transmitting a signal indicating the vehicle TR, the vehicle TR is controlled to advance / stop based on the advance / stop signals transmitted from the ground-side device 20 via the road-to-vehicle communication device 12 via the loop antenna.

The vehicle-side control device 11 also controls the passing unit R based on communication data from the vehicle-to-vehicle communication device 13.
An algorithm (described later) for correcting the passing timing of the vehicles in Step 2 can be executed.

The ground-side device 20 is connected between a ground-side control device 21 that is responsible for a ground-side control center such as signal / security control, vehicle tracking, and course control, and the vehicle-side device 10 via each loop antenna. And a communication device 22 capable of road-to-vehicle communication.

The ground-side control device 21 includes, for example, a computer, and in this example, a signal indicating the presence on the running track R from two trains of vehicles TR, TR is transmitted via a loop antenna to the communication device. 22 and based on the received signals, the vehicles TR,
It grasps the positional relationship of the TRs, generates respective signals for traveling / stop so that the vehicles TR do not collide with each other, and transmits the respective signals to the vehicle TR from the communication device 22 via the loop antenna.

Next, the overall operation of this embodiment will be described with reference to FIG.

FIG. 2 shows an example of processing relating to passing control by the control system 1. First, as shown in FIG. 1, a case is considered where the vehicles TR, TR of the formation 1 and the formation 2 are present (stop) on the loop antennas 2C, 1C at the turning points P1a, P1b, respectively. At this time, a stop signal from the ground side control device 21 causes each loop antenna 2C,
The signal of 1C is "stop". Thereby, each vehicle TR of formation 1 and formation 2 maintains a stopped state.

In this stopped state, a control signal is output from the ground-side control device 21 to each of the vehicles TR, TR of the formations 1, 2, such that the signal state of each of the loop antennas 2C, 1C is "departure". . Thereby, the passing part R2 of the knitting 1
, The shuttle running of the vehicle of formation 2 is started via the line A of the passing part (step S1).
a, S1b).

At this time, the signal states of the loop antennas on the B line side of the passing portion R are B2C "departure" and B1C
Is "stop", BC is "stop", the signal state of each loop antenna on the A line side is A1C is "departure", A2C is "stop",
A control signal is output from the ground-side control device 21 so that AC is "stopped" (steps S1a and S1b).

Next, in the case of formation 1, the vehicle TR is connected to the main line R
From 1 at the branch point P2a, proceed to the line B side of the passing part R,
When reaching the loop antenna B2C ahead (step S3a), the loop antenna A on the A-line side of the passing portion R
A control signal is output from the ground-side control device 21 so that the signal states of 2C and AC become “departure” (step S).
4a).

In the case of formation 2, the vehicle TR is connected to the main line R1.
At the branch point P2b to the line A side of the passing portion R, and when it reaches the loop antenna A1C ahead (step S3a), the loop antenna B1 on the line B side of the passing portion R
A control signal is output from the ground-side control device 21 so that the signal states of C and BC become “departure” (step S4).
b).

As a result, the vehicle TR of formation 1 passes through the passing section R2 via the loop antennas B1C and BC on the B line side (step S5a), and moves from the branch point P2b to the main line R1.
To reach the antenna 1C at the target turning point P1b (step S6a). The vehicle TR of formation 2
Passes through the passing portion R2 via the loop antennas A2C and AC on the line A side (step S5b), enters the main line R1 from the branch point P2a, and reaches the antenna 2C at the target turning point P1a (step S6b).

Next, in the above-described vehicle traffic system 100, each of the vehicles TR, TR of the formation 1 and the formation 2 has an error in the passing time at the passing portion R2, and the passing portion B
Let us consider a case where it is difficult to pass each other.

For example, a delay occurs in the vehicle TR of formation 1 before entering the passing section R2, so that the passing of the passing section R1 on the line B side is delayed, that is, the loop antenna B2C
Before reaching the top, the vehicle TR of the formation 2 is moved to the A of the passing part R1.
It is assumed that the vehicle enters the line side and goes through the loop antenna A1C to the A2C side. In this case, the signal of the loop antenna A2C remains "stop". This is because the entry of the vehicle TR of formation 1 into the line B is delayed and has not yet passed over the loop antenna B2C. As a result, the vehicle TR of formation 2 stops on the loop antenna A2C on the line A side of the passing portion R1.

In order to avoid such a situation that the other vehicle TR is decelerated and stopped at the passing section R1 due to the delay of one vehicle TR, in this embodiment, the vehicle traffic system 100 is used.
A method of correcting the passing timing by applying inter-vehicle communication between vehicles is applied to the inside. An example of this correction method will be described with reference to FIGS.

FIG. 4 shows each vehicle T of formations 1 and 2 shown in FIG.
The following describes an example of processing for recognizing a delay in the passing section R2 based on the positional relationship between R and TR and informing a vehicle on the other side of the delay by inter-vehicle communication.

First, the vehicle-side control devices 11, 11 of the vehicles TR, TR of the formations 1, 2, which are the objects to be passed, enter the main line (single-track section) immediately before the vehicles TR, TR enter the passing portion R2. ) R1, R3, predetermined points P3a, P
At the time when the vehicle has passed through 3b, a signal relating to the absolute position from the loop antenna 30 at the points P3a and P3b is received via the road-vehicle communication device 12, thereby inputting the passing time T1 (step S11).

Then, the vehicle-side control devices 11 and 11 refer to the passing time T2 at the predetermined points P3a and P3b set in advance based on the driving curve created in accordance with the diagram (passing time) (step S12). ), The difference is calculated by comparing the two passing times T1 and T2 (step S13).

Next, the vehicle-side control devices 11 and 11 determine whether or not the errors calculated above can be eliminated by the own vehicle from the predetermined points P3a and P3b to the arrival at the passing section (step S13). By this judgment, YE
In the case of S, the own vehicle changes the driving conditions such as the traveling speed, and the processing here ends. In the case of NO in the above judgment, the delay time ΔT of the passing time is calculated (step S
15), and transmits the ΔT to the vehicle TR on the other side of the passing object via the inter-vehicle communication device 13 (step S1).
6).

As a result, as shown in FIG. 5, the control device 11 of the vehicle T of the other party inputs the delay time ΔT of the passing time of the other party by inter-vehicle communication (step S21),
The driving conditions such as the traveling speed are corrected in accordance with the passing time delayed by ΔT (step S22). This makes it possible to minimize the error at the passing portion R2.

Therefore, according to this embodiment, when the passing vehicle approaches the passing portion, the position and speed of the vehicle to be passed are exchanged by inter-vehicle communication.
If the target vehicle has a delay, the correction is performed at that point, so that inconveniences such as stopping due to the delay can be avoided, and the vehicles can pass smoothly without stopping. Becomes

Although the present embodiment is applied to a shuttle type vehicle traffic system, the present invention is not limited to this, and other vehicle traffic systems such as railways and monorails, and IMTS
The present invention can be applied in any case as long as it is a vehicle traffic system having a passing part on a vehicle running track, such as a new generation traffic system such as the above.

In this embodiment, a method of correcting the passing timing by using inter-vehicle communication is adopted. However, the present invention is not limited to this. For example, a control center or roadside equipment is provided on the ground side. In the case of such a system, vehicle delays are recognized by road-to-vehicle communication from a traffic control center, etc.
Based on this, the passing timing is corrected, and the control of the running of the vehicle such that the passing is possible at that timing is also applicable.

In the present embodiment, a loop coil is applied as a position correcting device. However, the present invention is not limited to this, and a communication device such as a transponder capable of notifying the vehicle side of the position at a predetermined position. If applicable, it is applicable.
