Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motorcycle riding simulation apparatus for changing the behavior of a vehicle body of a simulated motorcycle according to an operation of a passenger.

[0002]

2. Description of the Related Art In a riding simulation system for reproducing the behavior of an actual two-wheeled vehicle using a simulated two-wheeled vehicle, it is necessary to reproduce a roll motion in which the vehicle body of the simulated two-wheeled vehicle is swung in the vehicle width direction. As a riding simulation device for a two-wheeled vehicle capable of reproducing such a roll motion, for example, according to Japanese Utility Model Laid-Open No. 62-1688, a vehicle body of a simulated two-wheeled vehicle is swingably held by a longitudinal roll shaft in the vehicle length direction. At the same time, there is known one in which the vehicle body is elastically supported by a spring in the vehicle width direction. In this structure, the steering wheel is fixed to the vehicle body, and during cornering or the like, a roll movement is given to the vehicle body against the biasing force of the spring only by the weight movement performed by the occupant.

[0003]

In an actual two-wheeled vehicle, the occupant operates the steering wheel while moving the weight when cornering. For example, when cornering to the left with respect to the traveling direction, the steering wheel is operated at the start of cornering. Turn it slightly to the right, that is, operate the reverse handle to make the vehicle fall to the left, then move the weight to the left while returning the handle, and further cut the handle to the left by a certain amount to perform cornering. . Therefore, if the steering wheel is fixed to the vehicle body as in the above-described conventional example, the actual behavior of the motorcycle cannot be reproduced, and the occupant feels uncomfortable.

In view of the above problems, it is an object of the present invention to provide at low cost a riding simulation device for a two-wheeled vehicle, which can reproduce the rolling motion that causes the vehicle body to be tilted by operating the reverse steering wheel at the start of cornering. And

[0005]

In order to achieve the above object, the present invention is a riding simulation for reproducing the behavior of an actual two-wheeled vehicle by a simulated two-wheeled vehicle swingably supported by a longitudinal roll shaft in the vehicle length direction. In the device, a handle is rotatably supported on the simulated two-wheeled vehicle, and is interlocked with the rotation axis of the handle and is moved from the center line of the simulated two-wheeled vehicle to the opposite side to the rotation direction of the rotation axis. It is characterized in that a moving counterweight is provided.

[0006]

When the steering wheel is turned, the counterweight moves from the center line of the simulated motorcycle to the side opposite to the side where the steering wheel is cut, and the simulated motorcycle falls to the side where the counterweight has moved, that is, the side opposite to the side where the steering wheel is turned. In this way, the roll motion that causes the vehicle body to be tilted by operating the reverse steering wheel at the start of cornering is reproduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, A is a simulated motorcycle, and an occupant B of the simulated motorcycle A is a situation change such as a landscape displayed on a monitor C such as a CRT arranged in front of the simulated motorcycle A. The simulated two-wheeled vehicle A is operated according to A frame-shaped vehicle body 1 is built in the simulated motorcycle A, and the vehicle body 1 has a first roll shaft 4 which is long in the vehicle longitudinal direction of the simulated motorcycle A.
It is held swingably by 1. The vehicle body 1 has a lower vehicle body 13 connected to the first roll shaft 41 at an intermediate position in the vertical direction, and an upper portion which is connected at the upper end of the lower vehicle body 13 via a rotation shaft 12 and which is long in the vehicle length direction. It is composed of the vehicle body 11. An actuator 14 such as a fluid pressure cylinder is provided between the upper vehicle body 11 and the lower vehicle body 13.
The upper vehicle body 11 swings in the front-rear direction by the operation of the actuator 14, so that so-called pitch movement can be reproduced.

A rotary shaft 22 is rotatably supported by a front end of the upper vehicle body 11 at a predetermined caster angle, and a handle 2 is connected to an upper end of the rotary shaft 22. Further, at the lower end of the rotating shaft 22, a counterweight 21 is deviated from the axis of the rotating shaft 22 rearward in the vehicle length direction by a predetermined distance.
Is attached. Therefore, when the handle 2 is turned to the right, for example, the counterweight 21 moves to the left with respect to the center line of the simulated motorcycle A.

On the other hand, at the lower end of the lower vehicle body 13, the first
A fixed weight 31 and a lifting weight 32 are provided so as to be located further below the roll shaft 41. The fixed weight 31 is fixed to the lower end of the lower vehicle body 13 in order to balance the weights of the simulated motorcycle A and the occupant B located above the first roll shaft 41. The lifting weight 32 is erected between the servo motor 33 fixed to the lower vehicle body 13 and the fixed weight 31,
Ball screw 3 driven to rotate by the servomotor 33
4 and is screwed to and held between the fixed weight 31 and the first roll shaft 41 with the lower vehicle body 13 as a guide. When the vehicle travels at a low speed, the lifting weight 32 is raised to reduce the roll rigidity, and the lifting weight 32 is lowered to increase the roll rigidity as the traveling speed increases, so that the passenger B does not feel uncomfortable. did.

By the way, the first roll shaft 41 is mounted on the base 5
A second roll shaft 51 provided parallel to the first roll shaft 41 above is pivotally supported on the upper end of a roll arm 4 which is swingably mounted on the base 5. First
The swing angle of the roll shaft 41 with respect to the roll arm 4 is detected by the angle sensor 42. In addition, the roll arm 4
Includes a pair of stoppers 4 for elastically sandwiching the lower vehicle body 13 from both sides in the vehicle width direction via springs 44 and holding the roll position of the vehicle body 1 at a neutral position with respect to the roll arm 4.
3 is provided. On the other hand, the roll arm 4 itself is
A nut 54 that is swung by a servo motor 52 connected to a base 5 by a rotary shaft 56 and that is screwed into a ball screw 53 that is rotationally driven by the servo motor 52.
And an arm 55 standing upright from the second roll shaft 51 are rotatably connected.

According to the above configuration, when the occupant B performs various operations such as accelerator, brake, shift change, etc. with each lever (not shown), the situation displayed on the monitor C changes according to each of these operations, and the occupant also changes. B performs each operation according to the change of the display. Here, for example, when turning leftward in the traveling direction, at the start of turning, the occupant B almost unconsciously turns the steering wheel 2 slightly to the right. Then, the counterweight 21 moves to the side opposite to the direction in which the handle 2 is turned, that is, to the left side, and the center of gravity of the entire simulated motorcycle A or occupant B pivotally supported by the first roll shaft 41 moves. It deviates to the left, which is the direction. Due to the deviation of the center of gravity, the simulated two-wheeled vehicle A tries to fall to the left around the first roll shaft 41, and the occupant B shifts his / her weight to the left with this as a trigger. Center and lean to the left. Since the simulated two-wheeled vehicle A is biased to the neutral position by the spring 44 via the lower vehicle body 13, if it is tilted by a small amount, the first roll shaft 4
No further tilting occurs with respect to No. 1, but the controller (not shown), which has detected the small amount of tilting by the angle sensor 42, drives the servomotor 52 to roll to the left around the second roll shaft 51. Start operation. Further, the occupant B turns the steering wheel to the left with the start of this rolling operation, but since the occupant B has already moved to the left, the steering wheel 2 is turned to the left side and the counterweight 21 becomes the center of the simulated motorcycle A. The simulated motorcycle A does not stand up even if it moves to the right side of the line, and keeps the cornering state while leaning to the left side. In order to end the cornering state and return to the straight-ahead state, the occupant B may move his / her weight to the right. This weight movement causes the first roll shaft 41 to be returned, and the angle sensor 42 detects this and the servo motor 52 is turned on. Operate to return the simulated motorcycle A to the standing state.

By the operation of the actuator 14, the front of the upper vehicle body 11 is lifted during acceleration operation and the front of the upper vehicle body 11 is lowered during brake operation to reproduce the actual behavior of the two-wheeled vehicle even in pitch motion. You can

By the way, in the above implementation, the inclination of the simulated two-wheeled vehicle A due to the movement of the weight of the occupant B is detected on the first roll shaft 41, and the simulated two-wheeled vehicle A itself is tilted about the second roll shaft 51. A servomotor may be connected to the shaft 41, and the simulated two-wheeled vehicle A itself may be tilted about the first roll shaft 41 and the second roll shaft 51 may be omitted. In this case, the stopper 43 may be swung by the servo motor about the first roll shaft 41, and the simulated two-wheeled vehicle A may be tilted via the swinging stopper 43.

Although the counterweight 21 is directly attached to the rotary shaft 22 in the above-mentioned embodiment, the counterweight 21 is attached to the rotary shaft 22.
A moving amount amplifying unit such as a link mechanism may be provided between the rotating shaft 22 and the rotating shaft 22 to amplify the rotating amount of the rotating shaft 22 and move the counterweight 21 largely.

[0015]

According to the present invention, the behavior of the two-wheeled vehicle due to the operation of the reverse steering wheel at the start of cornering can be reproduced without giving the occupant a feeling of discomfort, and the structure is such that the counterweight is interlocked with the rotating shaft of the steering wheel. The control system does not become complicated simply by moving it, and a simulation device can be provided at low cost.
