A configuration for guiding the light to the central portion will be described. <B> First Detection Element 21 The first detection elements 21 (a1 to a18) are arranged in a row at a predetermined interval on the upper part of the approach road along the guiding direction of the vehicle. The first detection element is electrically connected to the control device 2 via the signal control line 24. When a vehicle comes in,
The first detection elements (a1 to a18) detect the entry position of the vehicle.

<B> Mobile unit 28 The rail 25 is provided above the approach path of the vehicle. The moving body 28 is controlled along the rail 25 in forward and backward directions and at an arbitrary speed. The wheels 26 are driven by a motor or the like and controlled by the control device 2. Since the front portion of the moving body 28 may collide with the vehicle, the spring 27 is attached to the upper end.

<C> Second detection element 22 Two second detection elements (b1, b2) are provided on the moving body 28.
Is attached. The second detection elements (b1, b2) are electrically connected to the control device 2 via the signal control line 24. When the vehicle approaches the moving body 28, first, the second detection element b1 detects the position of the vehicle. Further, since the second detecting element b2 is also detected when approaching, the relative position of the vehicle with respect to the moving body 28 can be detected. Therefore, the moving body 28 can be retracted in accordance with the entry of the vehicle so as to keep a constant distance from the vehicle. That is, when only the second detection element b1 detects a vehicle, the moving body 28 moves backward at a constant speed, and when the second detection element b2 further detects a vehicle, the moving speed is increased.

<D> Display Device 1 The display device 1 is attached to the front portion of the moving body 28 at a position where the driver can easily see it, and gives a driving instruction to the driver. The display control of the display device 1 is performed by the control device 2 based on the vehicle position detection signal from the detection element. The display unit of the display device 1 is shown in FIG. Forward 11 and throw 1 on the upper stage
Lamps indicating 2, stop 13, and retreat 14 are arranged. Either of the lamps will light up depending on the entry position of the vehicle. Eighteen lamps 15 (A1 to A18) indicating the entry position of the vehicle are arranged in the middle section. It is equal to the number 18 of the first detection elements (a1 to a18), and each of them corresponds to one to one. So when a vehicle travels a certain distance,
The lamps 15 (A1 to A18) corresponding to the distance are turned on. For example, only the lamp corresponding to the head position of the vehicle is turned on and the rest is turned off. At the lower stage, lamps, such as the side brakes 16, the keys 17, and the alighting 18, are arranged to call the driver's attention. After the vehicle can be stopped at a predetermined position, these lamps are alternately turned on so that the driver does not forget the necessary operation.

<E> Rotary Table 3 An example of the rotary table 3 is shown in FIGS. The turntable 3 is controlled to be rotatable about a vertical axis. On the upper surface of the turntable, a first correction roller 40 for correcting the wheel entry position and a third detection element 23 (c1, c2) for detecting the lateral position of the vehicle are arranged. Third detection element 2
3 is connected to the control device 2 via a signal control line 24. The second correction roller 50 has the same configuration, and the fourth detection element (not shown) detects the lateral position of the vehicle, and the second correction roller 50 is driven by the second drive unit in response to a signal from the control device 2. Driven by 62.

<F> Correction rollers 40, 50 The first correction roller 40 is composed of a plurality of roller groups 41, 42,
.., and arranged in parallel with the central contraction L of the turntable 3. Each correction roller is set to have a gap that prevents the tire from falling. The second correction roller 50 is also the first
It has the same structure as the correction roller 40. The lengths of the first correction roller 40 and the second correction roller 50 are formed with a margin such that all four wheels can ride even in a vehicle model in which the distance between the front wheels and the rear wheels is different. The driving of the first correction roller 40 is performed by the sprocket 41a, 42a, ... Provided at one end of each roller 41, 42 ,. The rollers 41, 42 on both sides of the center line L of the first correction roller,
. And 46, 47, ... Rotate in the same direction by the drive unit 61. Similarly, the second correction roller 50 also includes the drive unit 62.
The rotation is controlled by.

A method of guiding the vehicle will be described below. <B> Vehicle entrance / forward When the vehicle is parked, the moving body 28 is arranged near the entrance of the parking lot. When the vehicle enters the entrance of the parking lot, the display of the display device 1 is in front of the driver. At this time, the forward lamp 11 on the upper stage of the display device 1 is blinking. Further, when the vehicle moves forward, the first first detection element a1 detects an approaching vehicle and turns on the first lamp A1 in the middle stage of the display device 1. At the same time, the forward lamp 11 is changed from blinking to lighting. This display allows the driver to move forward with peace of mind. When the first second detection element b1 on the moving body 28 detects the vehicle, the moving body 28 is moved in the traveling direction of the vehicle, that is, moved backward. As the moving body 28 moves backward, the driver can naturally move the vehicle forward. This is replaced by the conventional method of guiding the vehicle by a human being's beckoning, and it suffices to drive the vehicle according to the movement of the display device 1, and even a beginner can easily drive the vehicle to a predetermined position.

<B> Vehicle deceleration When the speed of the vehicle is faster than the backward speed of the moving body 28, the second detecting element b2 next to the moving body detects the vehicle, and the slow speed of the upper stage of the display device 1 is detected. The lamp 12 blinks.
This alerts the driver to slow down.
At the same time, the backward speed of the moving body is increased so that the vehicle does not collide with the moving body. When the vehicle approaches the predetermined stop position,
The lamps (A9 to A12) are turned on. At the same time, the slow lamp 12 is turned on. Therefore, the driver can easily know that his vehicle is approaching the stop position.

<C> Stopping the Vehicle When the vehicle further advances and reaches the stop position, one of the stop lamps (A13 to A16) in the middle stage is turned on. The four lamps are provided for stopping because the range of the stopping position has a width. Therefore, if any of the lamps (A13 to A16) is lit, it indicates that the vehicle is in the stop position.

<D> Retreat of vehicle When the vehicle goes too far forward, the upper retreat lamp 14 is turned on and the lamp 15 corresponding to the middle retreat is also turned on. It is possible to know the extent of overshooting by the lamp 15 . It is sufficient to move the vehicle backward until the lamp 15 goes out, and move until the stop lamp 13 lights up.

<E> Lateral Correction of Vehicle In FIGS. 3 to 4, when the front wheels F, F ′ of the vehicle ride on the first correction roller 40 and move forward, the vehicle deviates from the center line L of the turntable 3. The third detection element c
1, c2 detects a vehicle and sends a signal to the control device 2. The control device 2 sends a signal to the first drive unit 61 to rotate the first correction rollers 41, 42, ... And 46, 47, .., so that the vehicle is positioned at the center of the turntable F. , F ′ are forcibly moved. At the same time, the control circuit 2 sends a signal to the stop lamp (stop display portion) 13 of the display device 1 to blink the stop lamp to notify the driver to stop the vehicle. When the vehicle is located at the center, the first drive unit 61 is stopped, the stop lamp 13 is turned off, and the forward 11 or slow 12 lamp is turned on. The driver moves forward according to the instruction of the display device, and the front wheels F and F'are the first
When the vehicle passes over the correction roller 40 and enters the second correction roller 50, the fourth detection element detects the vehicle, and when the position of the vehicle is laterally deviated, the second correction roller 50 rotates to center the vehicle. To move to. Rear wheels R, R
Similarly, the position of ′ is also corrected by the first correction roller 40.

The operation vehicle <f> lower lamp when it stops at a predetermined stop position, and the ramp 16 of the lower side brake lights, at predetermined time intervals, the ramp 17 of the key, get off the lamp 18 Turn on sequentially. In this way, the driver is alerted.

[0018]

The present invention having the above-described structure produces the following special effects. <B> Since the guide display device is placed on the front surface of the vehicle and moves backward together with the vehicle, the vehicle can be accurately moved to a predetermined position instead of the conventional human being beckoning to guide the vehicle. <B> Since the vehicle can be forcibly transferred laterally by the correction roller, even a beginner can accurately position the vehicle at a predetermined position.
