Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle spin reproduction method and a spin reproduction road.

[0002]

2. Description of the Related Art For example, as disclosed in Japanese Unexamined Patent Publication No. 10-105041, one step further is taken from the acquisition of basic driving techniques to cope with various road conditions that may actually occur. There are known training routes to reproduce the behavior of vehicles and to experience them. Such a training course requires safe and reliable reproduction of the actual situation for the students, and it is important for the students to drive the vehicle by themselves to create such a situation. It has become a challenge. In the experience of riding in a vehicle by an instructor,
Since the trainees are riding with a sense of security, because they do not actually grasp the steering wheel and because it is reproduced by the instructor, they can experience the behavior of the vehicle, but they can experience the tense feeling as a driver. I can't.

[0003]

However, there is a problem that it is difficult to create such a behavior of the vehicle that actually occurs without relying on the instructor. For example, it has been confirmed that accidents such as overturning accidents of large vehicles on highways and accidents caused by spins of passenger cars often occur when the course is changed in the latter half of the S-curve.
Such a situation cannot be reproduced on a normal road by a trainee who is not good at driving skills as compared with an instructor.

More specifically, for example, it is possible for the trainees to experience their own driving if it is a simple experience-based training such as a braking experience based on a signal of an instructor, such as a braking distance experience. For example, a spin experience with a steep steering wheel in an S-shaped traveling is extremely difficult because the trainee, who is the driver, has to create a bias in the load of the vehicle, especially in the vehicle width direction, due to the sudden steering wheel. Therefore, the present invention provides a spin reproducing method for a vehicle and a spin reproducing traveling path in which a learner can easily experience a spin situation by assisting a posture change of the vehicle even with his / her own driving skill. .

[0005]

In order to solve the above-mentioned problems, the invention described in claim 1 provides a traveling path (for example, a vehicle V for inclining a vehicle (for example, the vehicle V in the embodiment) in the vehicle width direction). The approaching route 2) in the embodiment is entered at a predetermined speed so that one of the vehicles becomes higher than the other, and then the vehicle is suddenly changed to one side, and immediately thereafter, changed to the other side. Is characterized by. With this configuration, when the vehicle suddenly diverts to one side, the other side of the vehicle sinks more than the already tilted state, and when the vehicle diverts to the other side immediately after that, the vehicle largely sinks. Since the other side of the existing vehicle is assisted to extend and the one side is depressed, a large biased load can be momentarily applied to one side of the vehicle to spin the vehicle.

[0006] The invention described in claim 2 is characterized in that the course change is performed on a road surface having a low friction coefficient. With this configuration, it is possible to further reduce the grip force of the vehicle when the course is changed.

According to the third aspect of the invention, an approach area (for example, the approach area S in the embodiment) and a course change area (for example, a course change area in which a vehicle traveling in the approach area can be changed in front of the approach area (for example, A course changing region H) according to the embodiment is provided, and the vehicle is a spin reproducing route that reproduces spin by changing the course in the course changing region when entering from the approach region, and the course changing region is set as a low friction coefficient road surface. However, on the road surface on the trailing end side of the run-up area and on the wheel (for example, the wheels WR, WL in the embodiment) on the side where the course is changed, a mound portion having a height higher than that of the general road surface (for example, The cant portion 7) in the form is formed along the traveling direction, and the end portion of the mound portion is formed to extend in the course changing direction. With this configuration, when the wheels on one side of the vehicle traveling in the approach area enter the course changing area while riding on the mound section and change the course to one side, which is one side, the vehicle tilts by the mound section. The vehicle in the state of sinking into the other side further greatly, and immediately after that, when the vehicle diverts to the other side,
When one side of the vehicle disengages from the mound, the other side of the vehicle, which has been greatly depressed, extends and helps the other side to sink, so that a large biased load is momentarily applied to one side of the vehicle to create a low friction coefficient road. The vehicle can be spun in the rerouted area.

According to a fourth aspect of the present invention, the mound portion extends from a side portion on the terminal end side of the running area to a corner portion (for example, the guide portion 4 in the embodiment) formed by the running area and the course changing area. It is characterized by being a cant portion that gradually rises from the inner side toward the outer side. With this configuration, if the wheels of the vehicle are in contact with the cant portion, the vehicle can be reliably tilted in the vehicle width direction even if the vehicle is slightly displaced in the vehicle width direction. It will be possible.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a spin reproducing path 1 installed in a traffic training center. The spin reproducing path 1 is provided in a training facility for safe driving, which is one step further from the acquisition of basic driving skills. This training facility is a training facility where you can experience safe driving by reproducing the behavior of the vehicle and experiencing it in response to various road conditions that will actually occur. Road 1 is designed so that a trainee having ordinary driving skill can easily reproduce the spin by his / her own driving without the help of an instructor.

The spin reproduction traveling path 1 is provided with an approach area S having an approach path (running path) 2 and a course changing area (low friction coefficient path) H in front of the approach area S in the running direction. The change area H has a plurality of course changing traveling paths 3 for changing the course of the vehicle V traveling in the approach area S so as to reproduce the spin. The runway 2 is a runway for the vehicle V driven by each student to wait in order and accelerate the vehicle V to a predetermined speed (for example, about 50 to 60 km / h). The run-up area S provided with is a road surface having a normal friction coefficient (for example, about 0.6 to 0.7 μ).

Two runways 2 can be selected from a right runway 2R for experiencing a spin to the right and a left runway 2L for experiencing a spin to the left. Also,
Both side edges of the runway 2 are connected to a course changing region H, which is wider than the runway region S, through the guide portions 4 opened at 45 degrees. The approach area S may have the same width as the course changing area H without providing the guide portion 4. Course change area H is runway 2
By changing the course of the vehicle V that has entered from
And a friction coefficient smaller than that in the run-up area S (for example, about 0.45 to 0.6 μ) around the entire area where the spinning is actually performed or around the entire area.
It is the road surface. Specifically, in order to obtain such a low friction coefficient road surface, for example, a method of spraying water on a normal road surface using a water sprinkling facility, applying road surface coating, laying a material having a low friction coefficient on the road surface, etc. Can be adopted, but unlike a road where you can simply experience a spin, in order for the vehicle to easily experience a spin on a normal road surface due to S-shaped traveling, a watering that is realistic for the trainees It is preferable to adopt the low coefficient of friction of the road surface.

The course changing path 3 is located at a central portion on the extension of the approaching path 2 and has the right approaching path 2R and the left approaching path 2
A central traveling road 3C is provided so as to straddle L, a right first traveling road 3R1 is provided on the right side and a left first traveling road 3L1 is provided on the left side in the vehicle traveling direction so as to sandwich the central traveling road 3C. Further, on the outside of the right first road 3R1, the second right road
The traveling road 3R2 is provided and the left first traveling road 3L1
The left second traveling path 3L2 is provided outside of.

The first stopped vehicle is designed to partially obstruct the left side and the right side of the path, regardless of whether the vehicle approaches from the right approach road 2R or the left approach runway 2L, near the entrance of the central running path 3C. Identification devices 6 and 6 assuming V1 are arranged.
The identification tools 6 and 6 assuming the first stopped vehicle V1 are the starting points of the S-shaped traveling of the vehicle V traveling on the approach road 1
The purpose is to change the course for the second time.

On the right first traveling road 3R1, there are arranged identification tools 6, 6 which are assumed to be the right second stopped vehicle V2R which is the starting point of the second course change of the S-shaped traveling from the right approaching road 2R.
Specifically, the identification tools 6 and 6 assuming the right second stopped vehicle V2R generate the timing of the second course change to the left performed immediately after the first course change to the right for the S-shaped traveling. It is arranged for. The arrangement positions of the identification tools 6 and 6 assuming the right second stopped vehicle V2R are arranged at positions away from the first stopped vehicle V1 to the extent that a collision does not occur in consideration of the traveling distance of the spun vehicle.

In addition, the left approach runway 2 is provided on the left first runway 3L1.
The identification tools 6 and 6 are provided on the assumption that the left second stopped vehicle V2L is the starting point of the second course change of the S-shaped traveling from L. The identification tool 6, which assumes the left second stopped vehicle V2L
6 is arranged in order to create the timing of the second course change to the right immediately after the first course change to the left of the S-shaped traveling. The positions of the identification tools 6 and 6 assuming the left second stopped vehicle V2L are also arranged at positions far from the first stopped vehicle V1 to the extent that collision does not occur in consideration of the traveling distance of the spun vehicle. It should be noted that the identification tools 6, 6 assuming these right second stopped vehicle V2R and left second stopped vehicle V2L
It is possible to arrange both of them for simultaneous training on the left and right, but it is also possible to arrange only one of them depending on the training schedule situation and carry out on one side only.

Here, a cant portion (mound portion) 7 having a height higher than that of a general road surface is provided in the vehicle traveling direction on the wheel contact surface on the road surface on the terminal side of the approach area S on the side where the course is changed. A pair of left and right sides are formed along the left and right, and the traveling direction terminal portions of the respective cant portions 7 are formed to extend in the course changing direction. Specifically, the cant portion 7 is provided along the linear portion 7A on the end side of the running area S and the guide portion 4 which is a corner portion formed by the running area S and the course changing area H. The arcuate portion 7B is provided, and each cross-sectional shape gradually rises while inclining from the inner side to the outer side.

That is, the cant portion 7 on the right side is the right runway 2
In R, the part where the right wheel WR of the right approach road 2R contacts the ground (see FIG. 6).
And the front part of the vehicle V from the right approach lane 2R has just entered the lane change area H, and the right wheel WR passes through when the lane is changed to the right. The cant portion 7 on the left side is formed along the guide portion 4 on the left side of the left runway 2L on the left wheel W of the left runway 2L.
Immediately after the part where L touches the ground and the front part of the vehicle V from the left approach road 2L enters the course change region H, the left first wheel 3L1 on which the left wheel WL passes when the course is changed to the left. It is formed along the guide portion 4 at the entrance.

In the straight portion 7A of the cant portion 7, the outer edge is formed along the runway 2, and the parting line of the inner edge of the cant portion 7 in the running direction is close to the center portion of the approach area S near the entrance. In contrast, it is formed diagonally. As specific dimensions, for example, the width dimension d1 = 1.5 m and the arrangement length l1
= 8 m. The arcuate portion 7B of the cant portion 7,
That is, at the position along the guide portion 4, the outer edge is formed along the guide portion 4, the parting line of the inner edge is formed in an arc shape, and coincides with the end edges of the right first traveling road 3R1 and the left first traveling road 3L1. It is formed up to the position. As a specific dimension, for example, a distance d2 = 2.8 m from the inner parting line and a distance l2 = 2 m from the end of the straight portion of the cant portion 7 can be set. Further, as shown in FIG. 4, the straight portion 7A of the cant portion 7 is formed in a cross-sectional shape whose height dimension rises while inclining from the inner side to the outer side. For example, the gradient HI / D thereof is 6/110. Formed in a degree, arcuate portion 7B
Is also formed with a similar gradient. In addition, W in FIGS. 2 and 3 indicates a lane marking.

Next, the operation of this embodiment will be described with reference to FIGS. Here, in the following description, the right approach road 2
The case where the spin of the vehicle is reproduced using R will be taken as an example.
The vehicle V in the standby state at the start end side of the right approach road 2R starts traveling by the start display of the signal 5 as shown in FIG. 5 (position (1) in FIG. 1), and as shown in FIG. When the right wheel WR is ridden on the portion 7 (position (2) in FIG. 1), the vehicle V is inclined in the vehicle width direction and has a traveling posture in which the right side of the vehicle V is higher than the left side. Here, since the inner parting line near the entrance of the cant portion 7 is inclined so as to be directed toward the central portion, the vehicle V can smoothly climb on the cant portion 7 and shift to the inclined posture.

Next, the vehicle V travels toward the course changing region H in this leaning posture, and in order to avoid the identifying tools 6 and 6 assuming the first stopped vehicle V1, the straight portion 7A of the cant portion 7 is used.
When the course is changed to the right (position (3) in FIG. 1) near the end of the vehicle (position (3) in FIG. 1), the vehicle V with the right wheel WR in contact with the arcuate portion 7B is further sunk in the left direction. A large force acts. Therefore, the arcuate portion 7B of the cant portion 7
After passing through the vehicle V, the vehicle V is largely tilted on the left side (position (4) in FIG. 1). In this state, in order to avoid the identifying tools 6 and 6 which are assumed to be the right second stopped vehicle V2R in front of the vehicle, the course of the vehicle is largely changed to the left side. As shown in FIG. 8, the right side inclines in the vehicle width direction in the direction in which the right side is largely lowered (position (5) in FIG. 1). Therefore, the wheels WR and WL of the vehicle V are not supported because the course change region H has a low friction coefficient road surface due to a sudden steering wheel operation for returning the roll to the right side and changing the course to the left side. The grip in the vehicle width direction and the grip of the vehicle V in the counterclockwise direction due to turning are lost, and the vehicle V spins counterclockwise (position (6) in FIG. 1).

In this way, the vehicle V is steered to the right in the first half of the S-shaped traveling, so that the cant portion 7 has already been moved.
As a result, the vehicle V that is tilted to the left side further largely sank on the left side, and immediately after that, the course is changed to the right side, so that the left side of the vehicle V, which has been greatly depressed, extends and the right side sinks. The vehicle V can be spun by instantaneously applying a large biased load to the right side of V. As a result, the trainee can easily reproduce the spin state of the vehicle V and can experience the spin state by a simple operation of performing the S-shaped traveling by himself / herself.

Here, the cant portion 7 is provided along the linear portion 7A on the side of the trailing end of the running area S and the guide portion 4 which is a corner portion formed by the running area S and the course changing area H. Since each of the cross-sectional shapes gradually rises from the inner side to the outer side, the wheel WR or the wheel WL of the vehicle V is slightly touched by the vehicle V if the cant portion 7 is grounded. Even if there is a deviation in the vehicle width direction, the vehicle V can be reliably tilted in the vehicle width direction, so that the state in which the vehicle V spins can be reliably reproduced. In this way, even if the learner has only normal driving skills, the learner can drive himself without the help of an instructor to reproduce the spin state of the vehicle and experience a feeling of tenseness and be safe. You can check the need for driving.

The present invention is not limited to the above embodiment, and for example, the spin reproducing traveling path may be provided in a so-called driving school for the purpose of learning basic driving techniques. Further, the cant portion may be simply a mound portion which is higher than the general road surface.

[0024]

As described above, according to the invention described in claim 1, the spin state of the vehicle can be easily reproduced.

According to the invention described in claim 2, in addition to the effect of claim 1, the gripping force of the vehicle at the time of changing the course can be further reduced, so that the vehicle can be easily spun. effective. According to the invention described in claim 3, by utilizing the mound portion, the load deviated from one side to the other side in the vehicle width direction of the vehicle is sequentially applied without depending on the proficiency of the driver as much as possible. As a result, the spin state of the vehicle can be easily reproduced, so that the learner can experience that the vehicle spins by himself / herself. Therefore, there is an effect that a situation of an accident caused by a spin occurring in an S-shaped curve or the like can be safely created by one's own driving, and the necessity of safe driving can be experienced by oneself.

According to the invention described in claim 4, in addition to the effect of claim 3, if the wheel of the vehicle is in contact with the cant portion, even if the vehicle is slightly displaced in the vehicle width direction. Since the vehicle can be surely tilted in the vehicle width direction, it is possible to reliably reproduce the spinning state of the vehicle.
