## Background
TECHNICAL FIELD
This invention relates to a vehicle confronting apparatus and a confronting method for a vehicle.
BACKGROUND ART
Conventionally, as disclosed in JP, H06-331505, A, there is a well-known vehicle confronting apparatus that arranges a vehicle at a predetermined position and into a predetermined direction (posture). This device is used for various purposes, such as evaluation about whether or not the direction of (direction of an optical axis of) headlights of the vehicle or a backing guide monitor of the vehicle is proper, or about whether or not the alignment of wheels of the vehicle is proper.
The vehicle confronting apparatus described in JP, H06-331505, A, confronts the vehicle by moving a target vehicle onto the table, and by pushing side surfaces of the wheels of the vehicle so as to move the vehicle in the transversal direction.
However, since the vehicle confronting apparatus described in JP, H06-331505, A moves the vehicle by pushing the side surfaces of the wheels of the vehicle, elastic deformation remains in the wheels of the vehicle and hysteresis remains in an undercarriage (such as suspensions) of the vehicle after the vehicle reaches the confronting position.
Therefore, the confronting of the vehicle at the confronting position is not reflected on the actual traveling state of the vehicle, thereby reducing the reliability of the above-mentioned various evaluations based on the confronting.
Moreover, there is another well-known vehicle confronting apparatus which is named as a run-out-type confronting apparatus. As to this apparatus, the elastic deformation remaining in the wheels and hysteresis remaining in an undercarriage of the vehicle are removed while the wheels are supported and are driven rotationally.
However, as to the conventional run-out-type confronting apparatus, the vehicle entered in the apparatus may be deviated from the desired confronting position. In this case, it takes a long time to move the vehicle to the confronting position while removing the elastic deformation remaining the wheels and hysteresis remaining in the undercarriage of the vehicle, thereby reducing workability (productivity).
Moreover, as another problem, the run-out-type confronting apparatus, especially the wheel-supporting portion thereof for supporting the wheels, is enlarged, since the supporting members supporting wheels have to be large in the transversal direction enough to completely remove the lateral forces of the wheels (the forces of the wheels for pushing the ground sidewise) while the wheels of the vehicle are rotationally driven on the apparatus for a long time.
In addition, the enlargement of the wheel-supporting parts of the confronting apparatus increases the weight thereof. As a result, the lateral force may be insufficient to correspond to the weight of the supporting parts, so that it is difficult to remove the lateral force.
DISCLOSURE OF INVENTION
In consideration of the above-mentioned problems, the present invention is intended to provide a vehicle confronting apparatus and a confronting method for a vehicle so as to confront the vehicle surely for a short while.
The above-mentioned problems are solved by the following means according to the present invention.
According to the present invention, a vehicle confronting apparatus comprises: a guide-type confronting device guiding a wheel of a vehicle entering to a confronting position, and regulating both sides of the wheel of the vehicle; a run-out-type confronting device rotationally driving the wheel of the vehicle reaching the confronting position; and a control device controlling motions of the guide-type confronting device and the run-out-type confronting device. The control device cancels the regulation of the wheel by the guide-type confronting device within a period between a time of starting of the rotational driving of the wheel of the vehicle and a time when the rotation speed of the wheel reaches a predetermined run-out speed.
According to the present invention, the run-out-type confronting device comprises: a rotate means abutting against the wheel of the vehicle so as to rotationally drive the wheel; a support means supporting the rotation means movably in longitudinal and crosswise directions and turnably; a longitudinal move-restraining means to restrict the longitudinal moving of the rotate means, or to cancel the restriction; a crosswise move-restraining means to restrict the crosswise moving of the rotate means, or to cancel the restriction; and a turn-restraining means to restrict the turning of the rotation means, or to cancel the restriction. The control device cancels the restriction of the longitudinal moving of the rotation means by the longitudinal move-restraining means before the rotational driving of the wheel of the vehicle by the run-out-type confronting device is started. The control device cancels the restriction of the crosswise moving of the rotation means by the crosswise move-restraining means and the restriction of the turning of the rotation means by the turn-restraining means after the restriction of the wheel by the guide-type confronting device is canceled.
According to the present invention, a confronting method for a vehicle comprises: a vehicle entering process guiding a wheel of the vehicle, and entering the vehicle to a confronting position; a wheel restriction process regulating both sides of the wheel of the vehicle reaching the confronting position; and a run-out process rotationally driving the wheel of the vehicle reaching the confronting position, During the run-out process, the restriction of the wheel is canceled within a period between a time of starting of the rotational driving of the wheel of the vehicle and a time when the rotation speed of the wheel reaches a predetermined run-out speed.
According to the present invention, the run-out process is performed using a run-out-type confronting device. The run-out-type confronting device comprises: a rotation means abutting against the wheel of the vehicle so as to rotationally drive the wheel; a support means supporting the rotation means movably in longitudinal and crosswise directions and turnably; a longitudinal move-restraining means to restrict the longitudinal moving of the rotation means, or to cancel the restriction; a crosswise move-restraining means to restrict the crosswise moving of the rotation means, or to cancel the restriction; and a turn-restraining means to restrict the turning of the rotation means, or to cancel the restriction. The restriction of the longitudinal moving of the rotation means by the longitudinal move-restraining means is canceled before the rotational driving of the wheel of the vehicle by the run-out-type confronting device. The restriction of the crosswise moving of the rotation means by the crosswise move-restraining means and the restriction of the turning of the rotation means by the turn-restraining means after the restriction of the wheel by the guide-type confronting device is canceled.
Accordingly, since the wheel is regulated by the guide-type confronting device and is placed in the confronting position for a while after starting the rotational driving of the wheel, it takes a short time to place the vehicle at the confronting position, under the situation that the elastic deformation remaining in the wheel and the hysteresis remaining in base carriers of the vehicle are removed. That is, the vehicle can be confronted surely for a short while.

BEST MODE FOR CARRYING OUT THE INVENTION
A vehicle confronting apparatus 1, serving as one of embodiments of the invention, is descried as follows by referring FIG. 1 to FIG. 10.
As shown in FIG. 1, the vehicle confronting apparatus 1 is a device for confronting a passenger car 7, and mainly has a guide-type confronting device 2, a run-out-type confronting device 4, and a control device 6.
As shown in FIG. 2 to FIG. 4, the passenger car 7 serving as one of embodiments of the vehicle employing this invention has a right front wheel 8R, a left front wheel 8L, a right rear wheel 9R, and a left rear wheel 9L.
The “Vehicle” according to this invention includes not only a passenger car but also any travelable vehicles having wheels, such as a track, a trailer or various work vehicles. Therefore, it is not limited to the passenger car 7 of this embodiment.
“To confront the vehicle” means that the vehicle is arranged at a prescribed position (confronting position) and in a prescribed direction (posture).
Further, the confronting position of the vehicle confronting apparatus 1 according to this embodiment is defined as the position where the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L are disposed as drawn in two-dot chain lines in FIG. 2.
In the following, the guide-type confronting device 2 is described by referring FIG. 1 to FIG. 5.
The guide-type confronting device 2, serving as one of embodiments of the guide-type confronting device of this invention, guides each of the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and left rear wheel 9L of the passenger car 7 entering the confronting position, and regulates both sides of each of the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and left rear wheel 9L of the passenger car 7 reaching the confronting position.
As shown in FIG. 1, the guide-type confronting device 2 mainly has guide-type confronting units 20R, 20L, 21R, 21L, and sensors 22a, 22b for detecting a passing of the front wheels.
In the following, the guide-type confronting unit 20R is described by referring FIG. 5.
Incidentally, description of the guide-type confronting units 20L, 21R and 21L is omitted because the guide-type confronting units 20R, 20L, 21R, and 21L correspond to the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L of the passenger car 7, respectively, and have the basically same construction.
The guide-type confronting unit 20R guides the right front wheel 8R of the passenger car 7 entering the confronting position, and regulates the right front wheel 8R of the passenger car 7 reached the confronting position.
The guide-type confronting unit 20R mainly has an inner guide mechanism and an outer guide mechanism. The inner guide mechanism has an inner guide member 23a, ball screws 24a, 24a, bevel gears 26a, 26a, a rotary shaft 27a, a gear 28a, a gear 29a, a motor 30a. The outer guide mechanism has an outer guide member 23b, ball screws 24b, 24b, bevel gears 26b, 26b, a rotary shaft 27b, a gear 28b, a gear 29b, a motor 30b. 
In the following, the inner guide mechanism is described.
The inner guide member 23a is a cylindrical member extended in the entering direction of the passenger car 7 (direction of the arrow A). The inner guide member 23a is placed so as to face the inner surface of the right front wheel 8R of the passenger car 7 entering toward the confronting position.
Even if the right front wheel 8R is attempted to move to the inside of the inner guide member 23a, the inner surface of the wheel abutting on the inner guide member 23a prevents the wheel from moving to the inside of the member. That is, the right front wheel 8R is guided so as to move to the outside from the inner guide member 23a. 
The ball screws 24a, 24a are threaded on outer peripheral surfaces thereof, and are screwed to the front and rear end portions of the inner guide member 23a, respectively. Each of the ball screws 24a, 24a is disposed so as to have an axis thereof oriented substantially in the transversal direction of the passenger car 7 entering toward the confronting position, and is supported by bearings (not illustrated).
Each of bevel gears 25a, 25a is disposed on one end of each of the bawl screws 24a, 24a. Each of the bevel gears 26a, 26a meshes with each of the bevel gears 25a, 25a. 
The rotary shaft 27a is provided on opposite ends thereof with the bevel gears 26a, 26a, respectively, and the rotary shaft 27a is disposed so as to have an axis thereof oriented substantially in the entering direction of the passenger car 7, and is supported by bearings (not illustrated).
The gear 28a is a spur gear, which is disposed at middle part of the rotary shaft 27a. The gear 29a is a spur gear, which meshes with the gear 28a. 
The motor 30a is a servomotor, and the amount of the rotation (rotation angle) of the output shaft thereof is controllable. The gear 29a is disposed on the output shaft of the motor 30a. 
The ball screws 24a, 24a are rotated by rotationally driving the motor 30a, so that the inner guide member 23a, which meshes with the ball screws 24a, 24a, moves in the transversal direction of the passenger car 7 entering toward the confronting position
In the following, the outer guide mechanism is described.
The outer guide member 23b is a cylindrical member extended in the entering direction of the passenger car 7 (direction of the arrow A). The outer guide member 23b is placed so as to face the outer surface of the right front wheel 8R of the passenger car 7 entering toward the confronting position.
Even if the right front wheel 8R is attempted to move to the outside of the outer guide member 23b, the outer surface of the wheel abutting on the outer guide member 23b prevents the wheel from moving to the outside of the member. That is, the right front wheel 8R is guided so as to move to the inside from the outer guide member 23b. 
The ball screws 24b, 24b are threaded on outer peripheral surfaces thereof, and are screwed to the front and rear end portions of the outer guide member 23b, respectively. Each of the ball screws 24b, 24b is disposed so as to have an axis thereof oriented substantially in the transversal direction of the passenger car 7 entering toward the confronting position, and is supported by bearings (not illustrated).
Each of the bevel gears 25b, 25b is disposed on one end of each of the bawl screws 24b, 24b. Each of the bevel gears 26b, 26b meshes with each of the bevel gears 25b, 25b. 
The rotary shaft 27b is provided on opposite ends thereof with the bevel gears 26b, 26b, respectively; and the rotary shaft 27b is disposed so as to have an axis thereof oriented substantially in the entering direction of the passenger car 7, and is supported by bearings (not illustrated).
The gear 28b is a spur gear, which is disposed on a middle part of the rotary shaft 27b. The gear 29b is a spur gear, which meshes with the gear 28b. 
The motor 30b is a servomotor, and the amount of the rotation (rotation angle) of the output shaft thereof is controllable. The gear 29b is disposed on the output shaft of the motor 30b. 
The ball screws 24b, 24b are rotated by rotationally driving the motor 30b, so that the outer guide member 23b, which meshes with the ball screws 24b, 24b, moves in the transversal direction of the passenger car 7 entering toward the confronting position
By appropriately driving the motors 30a, 30b, the inner guide member 23a and the outer guide member 23b can be disposed so as to have respective prescribed spaces from the inner and outer surfaces of the right front wheel 8R of the passenger car 7 entering toward the confronting position, thereby guiding the right front wheel 8R. Moreover, after the passenger car 7 reaches the confronting position, the motors 30a, 30b are appropriately driven so as to narrow the interval between the inner guide member 23a and the outer guide member 23b, thereby regulating both sides of the right front wheel 8R.
Incidentally, “to regulate both sides of the wheel” means to restrict the movement of the wheel in the transversal direction (laterally) as far as possible while the wheel is allowed to rotate.
In this embodiment, the inner guide member 23a and outer guide member 23b are retained so as to have the interval therebetween which is a little larger than the width of the right front wheel 8R.
As shown in FIG. 5, a pair of guide members 31a, 31b are disposed rearwardly of the inner guide member 23a and outer guide member 23b of each of the guide-type confronting units 21R, 21L.
The pair of guide members 31a, 31b are members for easily guiding the wheels (the right front and rear wheels 8R and 9R, or the left front and rear wheels 8L and 9R) of the passenger car 7 entering toward the confronting position to the space between the inner guide member 23a and the outer guide member 23b of each of the guide-type confronting unit 21R, 21L. The pair of the guide members 31a, 31b are disposed at front ends thereof in the vicinity of the rear ends of the inner guide member 23a and the outer guide member 23b of each of the guide-type confronting units 21R, 21L, respectively, and the pair of guide members 31a, 31b are extended rearward so that rear ends thereof have a wider space therebetween (in a truncated chevron shape in plane view).
The sensors 22a, 22b for detecting a passing of the front wheels detect the right front wheel 8R and left front wheel 8L passing between the pair of guide-type confronting units 20R, 20L and the pair of guide-type confronting units 21L, 21R when the passenger car 7 enters the vehicle confronting apparatus 1 forward to the confronting position.
As shown in FIG. 2 to FIG. 4, the sensors 22a, 22b is disposed between the guide-type confronting units 20R, 20L and the guide-type confronting units 21L, 21R.
In this embodiment, the sensor 22a is a floodlight of an optical sensor, and irradiates (projects) infrared lasers toward the sensor 22b. The sensor 22b is a receiver of an optical sensor, and detects (receives) infrared lasers irradiated by the sensor 22a. The optical path irradiated by the sensor 22a is disposed so as to cross the passages of the right front wheel 8R and the left front wheel 8L of the passenger car 7 entering toward the confronting position.
The sensors 22a, 22b of this embodiment are composed of optical sensors. Alternatively, other compositions, such as a contact switch, an electrostatic capacity type sensor or the like, are adaptable for detecting the passing of the vehicle.
In the following, the run-out-type confronting device 4 is described by referring FIG. 1 to FIG. 4, and FIG. 6 and FIG. 7.

In the vehicle type setting process S110, an operator inputs the type of the passenger car 7 by using the input part 62. The inputted type of the passenger car 7 is memorized in the control part 61.
Incidentally, the kind of vehicle is inputted by an operator in this embodiment. Alternatively, the kind of vehicle can be set up by reading an IC tag or the like, that memorizes the kind of the vehicle and is put on the vehicle.
Moreover, the vehicle type setting process S110 is omitted when only one kind of vehicle is provided.
The first guiding process S120 is performed subsequently to finishing of the vehicle type setting process S110.
The first guiding process S120 is a process to move the inner guide members 23a and the outer guide members 23b of the guide-type confronting device 2 toward “the first guide position” in correspondence to the type of vehicle set in the vehicle type setting process S110, and to move the run-out-type confronting units 40R, 40L, 41R, and 41L of the run-out-type confronting device 4 toward the initial position, respectively.
In the first guiding process S120, the control part 61 moves the positions of the inner guide members 23a and the outer guide members 23b toward “the first guide position” for each of the guide-type confronting units 20R, 20L, 21R, and 21L respectively according to the information concerning the set type of vehicle in the vehicle type setting process S110, and the information previously memorized in the memory means concerning the tread of each type of vehicle (the distance between the right and left wheels).
As to the inner guide member 23a of each of the guide-type confronting units 20R, 20L, 21R, and 21L, “the first guide position” is defined as the position having a predetermined space from the inner side of the front wheels (the right front wheel 8R and the left front wheel 8L) of the passenger car 7 entering straightforwardly toward in the confronting position. As to the outer guide member 23b of each of the guide-type confronting units 20R, 20L, 21R, and 21L, “the first guide position” is defined as the position having a predetermined space from the outer side of the front wheels (the right front wheel 8R and the left front wheel 8L) of the passenger car 7 entering straightforwardly toward in the confronting position.
Moreover, the control part 61 moves the run-out-type confronting units 40R, 40L, 41R, and 41L of the run-out-type confronting device 4 toward the initial position respectively according to the information concerning the type of vehicle set in the vehicle type setting process S110, the information that is memorized in the memory means beforehand concerning the tread (the distance between the right and left wheels) and wheelbases (the distance between the front and rear wheels) of each type of vehicle.
The first entering process S130 is performed subsequently to finishing of the first guiding process S120.
The first entering process S130 is a process to enter the passenger car 7 forward in the vehicle confronting apparatus 1 so as to pass the right front wheel 8R between the inner guide member 23a and outer guide member 23b of the guide-type confronting unit 21R, and so as to pass the left front wheel 8L between the inner guide member 23a and outer guide member 23b of the guide-type confronting unit 21L, respectively.
In the first entering process S130, by an operator riding on the passenger car 7, the passage car 7 travels forward in the vehicle confronting apparatus 1 so as to pass the right front wheel 8R between the inner guide member 23a and outer guide member 23b of the guide-type confronting unit 21R, and so as to pass the left front wheel 8L between the inner guide member 23a and outer guide member 23b of the guide-type confronting unit 21L.
The sensors 22a, 22b for detecting a passing of the front wheels detect the passing of the front wheels of the passenger car 7 (the right front wheel 8R, the left front wheel 8L) when the front wheels of the passenger car 7 (the right front wheel 8R, the left front wheel 8L) having passed the guide-type confronting units 21R, 21L, and passed the optical axis of the sensors 22a, 22b. 
A buzzer (not illustrated) beeps when the sensors 22a, 22b detect the passing of the front wheels (the right front wheel 8R, the left front wheel 8L), so that the operator hearing the beeps stops the passenger car 7 temporarily.
At this moment, the rear wheels of the passenger car 7 (the right rear wheel 9R, the left rear wheel 9L) do not have reached the guide-type confronting unit 21R, 21L yet.
The second guiding process S140 is performed subsequently to finishing of the first entering process S130.
The second guiding process S140 is a process to move the inner guide members 23a and the outer guide members 23b of the guide-type confronting device 2 to “the second guide position” in correspondence to the type of vehicle set in the vehicle type setting process S110
In the second guiding process S140, the control part 61 moves the positions of the inner guide members 23a and the outer guide members 23b to “the second guide position” for each guide-type confronting units 21R, 21L respectively according to the information concerning the type of vehicle inputted in the vehicle type setting process S110, and the information that is memorized in the memory means beforehand concerning the tread of each type of vehicle (the distance between the right and left wheels).
As to the inner guide member 23a of each of the guide-type confronting units 21R, 21L, “the second guide position” is defined as the position having a predetermined space from the inner side of the rear wheels (the right rear wheel 9R and the rear front wheel 9L) of the passenger car 7 entering straightforwardly toward in the confronting position. As to the outer guide member 23b of each of the guide-type confronting units 21R, 21L, “the second guide position” is defined as the position having a predetermined space from the outer side of the rear wheels (the right rear wheel 9R and the left rear wheel 9L) of the passenger car 7 entering straightforwardly toward the confronting position.
The second entering process S150 is performed subsequently to finishing of the second guiding process S140.
The second entering process S150 is a process to enter the passenger car 7 forward in the vehicle confronting apparatus 1 so as to pass the right front wheel 8R between the inner guide member 23a and outer guide member 23b of the guide-type confronting unit 20R, so as to pass the left front wheel 8L between the inner guide member 23a and outer guide member 23b of the guide-type confronting unit 20L, so as to pass the right rear wheel 9R between the inner guide member 23a and outer guide member 23b of the guide-type confronting unit 21R, and so as to pass the left rear wheel 9L between the inner guide member 23a and outer guide member 23b of the guide-type confronting unit 21L, respectively.
In the second entering process S150, by the operator riding on the passenger car 7, the passenger car 7 travels forward in the vehicle confronting apparatus 1 so as to pass the right front wheel 8R between the inner guide member 23a and outer guide member 23b of the guide-type confronting unit 20R, so as to pass the left front wheel 8L between the inner guide member 23a and outer guide member 23b of the guide-type confronting unit 20L, so as to pass the right rear wheel 9R between the inner guide member 23a and outer guide member 23b of the guide-type confronting unit 21R, and so as to pass the left rear wheel 9L between the inner guide member 23a and outer guide member 23b of the guide-type confronting unit 21L, respectively.
Each of the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and left rear wheel 9L fits in the hollow formed at the gap between the rollers 42a, 42b of each of the run-out-type confronting units 40R, 40L, 41L, and 41R when the passenger car 7 reaches the confronting position. At this timing, the operator stops the passenger car 7.
Incidentally, in case that all the front and rear wheels have the same width and tread, the second guide process S140 and the second entering process S150 can be omitted.
The vehicle entering process S100 ends according to finishing of the second entering process S150.
The wheel regulation process S200 is performed subsequently to finishing of the vehicle entering process S100.
The wheel regulation process S200 is one of embodiments of the wheel regulation process of the invention, to regulate both sides of each of the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) of the passenger car 7 reaching the confronting position.
In the wheel regulation process S200, the interval between the inner guide member 23a and the outer guide member 23b of each of the guide-type confronting units 20R, 20L, 21R, and 21L is narrowed respectively. As a result, each of the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L is pushed and moved by the inner guide member 23a or the outer guide member 23b when the wheel is placed outside of the substantially center space that is formed between the inner guide member 23a and the outer guide member 23b. 
The run-out process S300 is performed subsequently to finishing of the wheel regulation process S200.
The run-out process S300 is one of embodiments of the run-out process of the invention, to drive the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) of the passenger car 7 reaching the confronting position.
As shown in FIG. 8 and FIG. 10, in the run-out process S300, the control part 61 controls the motions of the guide-type confronting device 2 and the run-out-type confronting device 4 as the following steps.
First of all, the restriction of longitudinal movement of the rollers 42a, 42b by the longitudinal move-restraining member 44 is canceled for each of the run-out confronting units 40R, 40L, 41R, and 41L (Time T1).
As a result, due to the self-weight of the passenger car 7, the rollers 42a, 42b of each of the run-out confronting units 40R, 40L, 41R, and 41L move conveniently for removing a part (especially, a longitudinal element) of the elastic deformation remaining in the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) and a part (especially, a longitudinal element) of the hysteresis remaining in the undercarriage of the vehicle.
Next, the control part 61 starts to rotationally drive each of the rollers 42a, 42b of the run-out confronting units 40R, 40L, 41R, and 41L, and accelerates the rotation speed of the rollers gradually (Time T2).
During this period, each wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) regulated by each of the guide-type confronting unit 20R, 20L, 21R, and 21L can be prevented from being swung widely by the shock generated by the rollers 42a, 42b when the rotation of the rollers 42a, 42b is started.
Next, the control part 61 increases the width of the gap between the inner guide member 23a and the outer guide member 23b for each of the guide-type confronting units 20R, 20L, 21R, and 21L, so as to start canceling the regulation of the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) (Time T3).
Next, the control part 61 increases the width of the gap between the inner guide member 23a and the outer guide member 23b for each of the guide-type confronting units 20R, 20L, 21R, and 21L, and finishes canceling the regulation of the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) when the increased width of the gap between the inner guide member 23a and outer guide member 23b becomes a predetermined value (that is, the gap becomes wide enough relative to the width of the wheels) (Time T4).
Incidentally, during this period, the rotation speed of the rollers 42a, 42b is increased before the speed of wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) reaches the predetermined run-out speed.
Next, the control part 61 cancels the restriction of the movement of the rollers 42a, 42b by the crosswise move-restraining member 45 for each of the run-out confronting units 40R, 40L, 41R, and 41L, and cancels the restriction of the turn of the rollers 42a, 42b by the turn-restraining member (Time T5).
Next, the control part 61 stops the acceleration of the rollers 42a, 42b when the rotation speed of the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) reaches the predetermined run-out speed (Time T6).
After that, the rotation speed of the rollers 42a, 42b is kept constant during the predetermined run-out time, then, the rotation speed of the rollers 42a, 42b is decreased gradually, and finally the rotational driving of the roller 42a, 42b is stopped.
In the status that the rotation speed of the rollers is kept constant during the predetermined run-out time, the fore-and-aft and left-and-right movement and the turn of the rollers 42a, 42b are allowed, and the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) are driven rotationally.
Thus, due to the self-weight of the passenger car 7, the elastic deformation remaining in the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) are removed, and hysteresis remaining in the undercarriage of the vehicle are removed.
Further, the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) are regulated by the guide-type conforming unit 20R, 20L, 21R, and 21L, and are placed in the confronting position before they are rotationally driven and for a while they are rotationally driven (for the period between Time T2 and Time T3).
Therefore, it takes a short time to place the vehicle at the confronting position under the situation that the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) are released from the elastic deformation and the undercarriage of the car is released from the hysteresis.
Incidentally, in this embodiment, the regulation of the crosswise movement of the rollers 42a, 42b by the crosswise move-restraining member 45 and the turn of the rollers 42a, 42b by the turn restraining member 46 are canceled within the period between the time of finishing canceling the restriction of the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) and the time of the rotation speed of the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) reaching the predetermined speed (from Time T4 to Time T6). However, the vehicle confronting apparatus and the confronting method for a vehicle of the invention are not restricted to the present embodiment. That is, it is also acceptable that, after the rotation speed of the wheels (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) reaches the predetermined speed (after time T6), the restriction of the crosswise movement of the rollers 42a, 42b by the crosswise move-restraining member 45 is canceled, and the restriction of the turn of the rollers 42a, 42b by the turn restraining member 46 is canceled.
Moreover, in this embodiment, the restriction of the crosswise movement of the rollers 42a, 42b by the crosswise move-restraining member 45 is canceled simultaneously with the cancellation of the turn of the rollers 42a, 42b by the turn restraining member 46. However, the vehicle confronting apparatus and the confronting method for a vehicle of the invention are not restricted to the present embodiment. That is, it is also acceptable that the restriction of the crosswise movement of the rollers 42a, 42b by the crosswise move-restraining member 45 can be canceled earlier or later than the cancellation of the turn of the rollers 42a, 42b by the turn restraining member 46.
As explained above, the vehicle confronting apparatus 1 according to an embodiment of the invention comprises: the guide-type confronting device 2; the run-out-type confronting device 4; and the control device 6. The guide-type confronting device 2 guides a wheel (any of the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) of the passenger car 7 entering to the confronting position, and regulates both sides of the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) of the passenger car 7. The run-out-type confronting device 4 rotationally drives the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) of the passenger car 7 reaching the confronting position. The control device 6 controls the motions of the guide-type confronting device 2 and the run-out-type confronting device 4. The control device 6 cancels the regulation of the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) by the guide-type confronting device 2 within a period between the time of starting of the rotational driving of the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) of the passenger car 7 and the time when the rotation speed of the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) reaches a predetermined run-out speed.
Therefore, the passenger car 7 can be confronted in short time and certainly (in the situation that the elastic deformation remaining the wheel and hysteresis remaining in the undercarriage of the car are removed in short time).
Further, the run-out-type confronting device 4 (each of the run-out-type confronting units 40R, 40L, 41R, and, 41L), comprises: the rollers 42a, 42b; the table 43; the longitudinal move-restraining member 44; the crosswise move-restraining member 45; and the turn-restraining member 46. The rollers 42a, 42b abut against the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) so as to rotationally drive the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) of the passenger car 7. The table 43 supports the roller 42a, 42b movably in longitudinal and crosswise directions and turnably. The longitudinal move-restraining member 44 restricts the longitudinal moving of the rollers 42a, 42b, or cancels the restriction. The crosswise move-restraining member 45 restricts the crosswise moving of the rollers 42a, 42b, or cancels the restriction. The turn-restraining member 46 restricts the turning of the rollers 42a, 42b, or cancels the restriction. The control device 6 cancels the restriction of the longitudinal moving of the rollers 42a, 42b by the longitudinal move-restraining member 44 before the rotational driving of the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) of the passenger car 7 by the run-out-type confronting device 4 is started. The control device 6 cancels the restriction of the crosswise moving of the rollers 42a, 42b by the crosswise move-restraining member 45 and the restriction of the turning of the rollers 42a, 42b by the turn-restraining member 46 after the restriction of the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) of the passenger car 7 by the guide-type confronting device 2 is canceled.
Therefore, the passenger car 7 can be confronted in short time and certainly (in the situation that the elastic deformation remaining the wheel and hysteresis remaining in the undercarriage of the car are removed in short time).
Moreover, the confronting method for a vehicle according to an embodiment of the invention
comprises: the vehicle entering process S100; the wheel restriction process S200; and the run-out process S300. The vehicle entering process S100 is performed to guide a wheel (any of the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) of the passenger car 7, and to enter the passenger car 7 to the confronting position. The wheel restriction process S200 is performed to regulate both sides the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) of the passenger car 7 reaching the confronting position. The run-out process S300 is performed to rotationally drive the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) of the passenger car 7 reaching the confronting position. During the run-out process S300, the restriction of the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) is canceled within a period between the time of starting of the rotational driving of the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) of the passenger car 7 and the time when the rotation speed of the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) reaches a predetermined run-out speed.
Therefore, the passenger car 7 can be confronted in short time and certainly (with in the situation that the elastic deformation remaining the wheel and hysteresis remaining in the undercarriage of the car are removed in short time).
Moreover, in the confronting method for a vehicle according to the embodiment of the invention, the run-out process S300 is performed using the run-out-type confronting device 4. The run-out-type confronting device 4 comprises: the rollers 42a, 42b; the rollers 42a, 42b; the table 43; the longitudinal move-restraining member 44; the crosswise move-restraining member 45; and the turn-restraining member 46. The rollers 42a, 42b abut against the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) so as to rotationally drive the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) of the passenger car 7. The table 43 supports the roller 42a, 42b movably in longitudinal and crosswise directions and turnably. The longitudinal move-restraining member 44 restricts the longitudinal moving of the rollers 42a, 42b, or cancels the restriction. The crosswise move-restraining member 45 restricts the crosswise moving of the rollers 42a, 42b, or cancels the restriction. The turn-restraining member 46 restricts the turning of the rollers 42a, 42b, or cancels the restriction. The restriction of the longitudinal moving of the rollers 42a, 42b by the longitudinal move-restraining member 44 is canceled before the rotational driving of the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, or the left rear wheel 9L) of the passenger car 7 by the run-out-type confronting device 4 is started. The restriction of the crosswise moving of the rollers 42a, 42b by the crosswise move-restraining member 45, and the restriction of the turning of the rollers 42a, 42b by the turn-restraining member 46 is canceled after the restriction of the wheel (the right front wheel 8R, the left front wheel 8L, the right rear wheel 9R, and the left rear wheel 9L) of the passenger car 7 by the guide-type confronting device 2 is canceled.
Therefore, the passenger car 7 can be confronted in short time and certainly (with in the situation that the elastic deformation remaining the wheel and hysteresis remaining in the undercarriage of the car are removed in short time).
