As shown in FIG. 2, the simulated motorcycle 4 has various sensor groups such as a steering wheel torque sensor 30, an accelerator opening sensor 32, and brake pressure sensors (34, 36), and a lighting switch 38, as in the actual vehicle. Switches such as the turn signal switch 40 and the pitch motor 4
2. Various motor groups such as a steering motor 44 are provided. FIG. 2 illustrates typical examples of the above-described various sensor groups, switch groups, motor groups, and the like, and a description thereof will be omitted.

The control console 10 includes a computer 12 and
The computer 12 includes a keyboard 46 and a joystick 48 as input means and a monitor 50 such as a CRT display as display means, which are connected to the computer 12.

The information transmitted from the control circuit 22 is basically the current position data, the current speed data, the current acceleration data, etc. relating to the steering operation of the simulated motorcycle 4.

The CGI generator 26 generates video information of a pre-stored travel road including a landscape in accordance with the input of the various data from the control circuit 22 in, for example, a frame unit. Indicates a simulated field of view.

The movement of the vehicle in the simulated field of view is also affected by the information provided by the sensors provided on the simulated motorcycle 4 as described above. For example, the lean torque sensor 3 provided below the driver's seat of the simulated motorcycle 4 detects the lean torque by shifting the weight of the user who is the driver, and the lean torque is mainly measured in the lateral direction of the motorcycle in the simulated visual field. Affect the behavior of

As described above, since the lean torque sensor 3 detects the lean torque due to the weight shift, the movement of the motorcycle in the simulated field of view differs depending on the weight of the occupant. This is relevant when practicing a two-seater simulated driving with the riding simulation apparatus.

In the present embodiment, in order to generate this two-seater situation, the behavior of the two-wheeled vehicle when the two-seater vehicle is actually realized is realized without two-seater riding on the simulated two-wheeled vehicle 4. Here, the seat and the lean torque sensor of the simulated motorcycle 4 will be described first.

FIG. 3 is a diagram showing the structure of the seat 54 on which the driver of the simulated motorcycle 4 sits, as viewed from the front of the simulated motorcycle 4.
It has a lean torque sensor 3 and a resilient member 56 for supporting the seat 54.

The lean torque sensor 3 has a movable cylindrical portion 3a.
The movable column 3a is inserted into the column 3b, and the movable column 3a is movable with respect to the column 3b. The lean torque is detected based on the degree of insertion of the movable column 3a into the column 3b. Therefore, the detection method may use, for example, a variable resistor.

With respect to the lean torque sensor 3, the seat 54 moves in the left-right direction 57 about the fulcrum 58. In accordance with this movement, the lean torque sensor 3 moves the movable column 3a as shown in FIG. By doing so, the lean torque is detected.

As means for generating a torque to be newly added for realizing a two-seater situation with respect to the detected lean torque, a joystick or a touch panel sensor is used to simulate a weight shift of a person sitting on a rear seat. I do.

The operation of the joystick and the touch panel sensor is usually performed by a person who is not the operator of the simulated motorcycle 4 while looking at the display 26 and the monitor 50.

Here, the joystick 48 will be described. FIG. 5 is a perspective view of the joystick 48. The joystick 48 includes a column portion 52 for operating to simulate weight shift and a base 100 supporting the column portion 52. As shown by a dotted line in FIG. 6, the operation can be performed by tilting in any direction. And this joystick 48
The direction and degree of inclination by operation are detected, and the detected data is transmitted to the control circuit 22 via the communication line 8 (see FIG. 1).

The joystick 48 does not always need to be connected to the control circuit 22 via the computer 12, but can be directly connected to the control circuit 22.

Next, a method of operating on the screen will be described.
FIG. 7 shows a screen displayed on the monitor 50. The monitor 50 has a touch panel sensor, and the background image 60 is the same image as the background seen by the user operating the simulated motorcycle 4, and a left-right button 62 is provided below the background image 60. The torque is generated by pressing the left / right direction button 62, and transmits the detected data to the control circuit 22 via the communication line 8.

Next, an actual processing method will be described.
FIG. 8 is a flowchart for obtaining a lean torque from the torque detected by the lean torque sensor 3 and the torque input by the joystick 48 or the left-right button 62 on the screen.

First, in step S101, the torque a detected by the lean torque sensor is read. For example, the torque value is set to a positive value if the torque value is applied in the right direction, and is set to a negative value if the torque value is applied to the left direction.

In the next step S102, the torque b inputted by the joystick 48 or the left / right direction button 62 is read. Thereafter, in step S103, an addition value c, which is the sum of the torques obtained in steps S101 and S102, is obtained.
At 104, the motion of the simulated motorcycle 4 is calculated using the added value c, and the calculation result is reflected on the simulated motorcycle 4 at step S105. At step S106, it is determined whether or not the vehicle is running. Is stopped, and if the vehicle is running, the process returns to step S101 and the process is repeated again.

Next, the torque detection based on the input operation of the joystick 48 or the left / right direction button 62 is performed by transmitting the torque value input from the joystick 48 or the left / right direction button 62 to the computer 12 via the communication line 8. It is detected by being notified by a message.

This process will be described with reference to FIG. 9. First, in step S201 in FIG. 9, a torque notification message transmitted from the computer 12 is received. This torque notification message is transmitted to the joystick 48 detected by the computer 12 as shown in FIG.
Alternatively, it has the torque data 68 of the direction and the torque value input by the left / right direction button 62.

Next, in step S202, the torque b (variable b) shown in step S102 of FIG. Then, in the next step S203, it is determined whether or not the vehicle is traveling. If the traveling is completed, the control is stopped.
01 and the process is repeated again.

As described above, in the riding simulation apparatus according to the present embodiment, the torque input by the joystick or the left-right button on the screen is added to the lean torque generated by the weight shift of the driver. Thus, it is possible to realize a two-seater situation without actually riding the two-seater.

As a result, it is not necessary to secure the strength of the simulated motorcycle and to create a rear seat, thereby making it possible to reduce the manufacturing cost of the riding simulation apparatus, and to add and reduce the input of the joystick and the left and right buttons. By changing the torque, it is also possible to realize a situation in which two persons are occupied by people of various different weights.

It should be noted that the riding simulation apparatus according to the present invention is not limited to the above-described embodiment, but can adopt various configurations without departing from the gist of the present invention.
