(Prior art) In this type of system, a system in which a film of a road is projected onto a screen using a projector and a simulated driver operates a simulated steering wheel while looking at the screen is well known. etc. are disclosed. In general, what is required of this type of system is that it accurately simulates the vehicle's driving fft, especially its drive characteristics and steering characteristics, and that it is properly operated based on the field of view of the screen. be.

(Problems to be Solved by the Invention) However, in the conventional system, a simulated driver's seat is provided and a simulated steering wheel is operated, so it is very difficult to obtain an actual driving sensation. In addition, the undulations and curves of the road shown on the screen are only perceived by the driver's eyes, and there are no changes in the simulated driver's seat that correspond to the road conditions shown on the screen, so the actual The problem was that it was impossible to physically feel the road conditions, and it was impossible to practice or test true driving skills.

The present invention has been made based on the above-mentioned problems, and has the same operational feeling as a driving operation on an actual road, faithfully judges the phenomenon corresponding to one driving operation, and improves two-wheeled vehicle driving technology. The purpose of this invention is to provide a simulated driving system for two-wheeled vehicles that can be tested.

(Operation) The control means compares the road information displayed on the screen with the operation signals of the simulated driver to judge the driving technique.

(Example) Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

In FIGS. 1 to 4, a fixing outer base 1 on which a two-wheeled vehicle can be placed has an inner base 3 disposed at the rear thereof so as to be movable up and down via a horizontal support shaft 2. A hydraulic cylinder 4 is installed vertically between the front side of the inner base 3 and the outer base 1, so that the inner base 3 can be raised and lowered around the support shaft 2, and the inner base 3 can be tilted in the vertical direction. ing.

5 is an upper base which is arranged on the upper surface of the width base 3 and can be rotated in the horizontal direction with respect to the middle base 3 by means of a vertical support shaft 6 provided at the rear; -4= middle base 3 and upper base 5; A hydraulic cylinder 7 installed approximately horizontally in the darkness applies pressure so that the upper base 5 does not move left or right when there is no load and stops on the center line. A plurality of bearings 8 are attached to the lower surface of the upper base 5 to assist the horizontal movement of the upper base 5.

A front drum 11 and a rear drum 11A are provided on the upper base 5 at positions where a front wheel 10Δ and a rear wheel 103 of a two-wheeled vehicle 10 operated by a simulated driver 9 can be placed, respectively.
A belt 12 is wound around the belts 11A and rotated at the same time.

Reference numeral 13 denotes a support mechanism that is provided on the upper base 5 and supports the vehicle body 10C so that it does not fall down when the two-wheeled vehicle 10 tilts left and right.The support mechanism 13 has a universal joint 13A that can tilt the vehicle body 10C left and right. Further, a leaf spring 14 is installed in the horizontal direction at the lower end of the support mechanism 13, that is, the two-wheeled vehicle 10 is elastically held vertically. Also,
A plurality of photocouplers 13B are disposed on the upper base 5 on the front surface of the support mechanism 13, making it possible to detect the left and right attitude angle of the two-wheeled vehicle 10.

A display device 15 is provided at a position in front of the two-wheeled vehicle 10 where the driver 9 can easily see it, and a photographed image of the passage, etc. is displayed on the display device 15.

This video is recorded on a video disc 16 or the like as shown in FIG. A normal video is recorded in a portion 16A of the video disc 16 that is displayed on the display device 15 in a real scene, and a normal video is recorded in an end portion 16B of the road such as the undulations and curves of the road in this real scene. Information is converted into digital signals and recorded. Therefore, an image of a road is reproduced on the display device 15, and road information corresponding to the image on the screen being reproduced is sent to the 1 arithmetic processing circuit 18 via the input circuit 17.

This H [numb processing circuit 18 also has 741 to Kabra 13C
The attitude angle of the two-wheeled vehicle 10 and the drum 11 detected by
The vehicle speed of the two-wheeled vehicle 10 detected by the rotation of the vehicle A is input, and driving signals such as these attitude angles and vehicle speed are compared with road information signals stored in the video disk 16 to ensure correct driving. determining whether the Further, the calculation processing circuit 18 controls the expansion and contraction of the hydraulic cylinders 4 and 7 via the drive circuit 19 based on the road information signal and the driving signal.

The operation of the system of the present invention configured as above will be described in detail.

On the video disk 16, road images actually captured are displayed in the screen range iIl' of the display device 15, as shown in FIG.
116A, and road information such as the ups and downs of the road and angles of curves for each screen displayed in the screen range 16Δ is stored as a corresponding digital signal at the edge 16B that deviates from the screen range 16A. .

The simulated driver 9 operates the two-wheeled vehicle 10, and the rear drum 11A rotates as the rear wheel (drive wheel) 10C rotates.The rotation of the drum 11A is then detected as a vehicle speed signal, converted into a digital signal, and calculated. The signal is sent to circuit 18.

The calculation processing circuit 18 controls the reproduction speed of the video disc 16 according to the vehicle speed, and the speed of the image displayed on the display device 15 changes according to the vehicle speed. And for example,
When the displayed road is an uphill slope, the road information stored on the screen corresponding to the uphill slope is sent to the calculation processing circuit 18.
Based on this information, the calculation processing circuit 18 extends the hydraulic cylinder 4 according to the inclination angle of the slope. As a result, the front side of the middle base 3 rises around the horizontal support shaft 2, and the middle base 3 tilts according to the plank road, allowing the simulated driver to experience the feeling of driving on a slope. can.

On the other hand, when the road displayed on the display device 15 curves left and right (then the road information of the angle of the curve stored on the screen corresponding to this curve is sent to the calculation processing circuit 18. At this time, the simulated driving Since the road displayed on the display device 15 is curved, the person 9 tilts the attitude of the two-wheeled vehicle 10 in accordance with this curve.This attitude angle is detected by the photocoupler 13C and is sent to the calculation processing circuit along with the vehicle speed at that time. 18. Then, the calculation processing circuit 18
calculates the centrifugal force at that time from the vehicle speed and attitude angle, expands and contracts the hydraulic cylinder 7 according to this centrifugal force and attitude angle,
The upper base 5 is rotated in the horizontal direction about a vertical support shaft 6 to give a driving feeling as if the two-wheeled vehicle 10 is cornering.

In addition, at this time, the calculation processing circuit 18 compares operation signals such as vehicle speed and attitude angle obtained by operating the motorcycle 10 with road information stored on the screen to determine whether cornering is accurate. At the same time, the display device 15 graphically displays whether the posture angle is sufficient.

In this way, the calculation processing circuit 18 reads the road information displayed on the display device 15, reads the driving technique operated by the simulated driver while looking at the displayed road, compares the two, and determines the driving technique. This is perfect for practicing on a two-wheeled vehicle. In addition, the middle base 3 moves up and down depending on the displayed road conditions, and the upper base 5 rotates depending on the centrifugal force, so you can get the feeling of actually driving.

Although one embodiment of the present invention has been described in detail above, it can be modified as appropriate within the scope of the gist of the present invention.

For example, when using this system to practice driving a two-wheeled vehicle, the judgment result can be used to teach the correctness of driving at that time, but when it is used as a game, the judgment result issued when driving incorrectly can be notified. It can also be played as a game where you compete for the number of driving mistakes or the number of driving mistakes in a predetermined period of time. Further, as a recording means for recording photographed roads and storing road information, a magnetic tape, a floppy disk, a compact disk, etc. may be used in addition to a video disk. Furthermore, the vehicle speed can also be detected from the slot of the two-wheeled vehicle 10 in addition to being detected by the rotation of the rear drum 11A. Also, without using an actual two-wheeled vehicle,
It is also possible to use a simulated two-wheeled vehicle, use a motor instead of an engine, link the slot to the motor, and transmit the rotation of this motor to the drum.

Furthermore, the slot may be linked to the drum and the vehicle speed may be detected from the drum.

[Effects of the Invention] As detailed above, according to the present invention, a display means installed in the front of a simulated two-wheeled vehicle operated by a simulated driver, and a road displayed on the display means are recorded, A recording means that stores road information for each screen as a digital signal, and an operation signal based on the vehicle speed and attitude angle of the two-wheeled vehicle obtained by the operation of the simulated two-wheeled vehicle are compared with the digital signal to determine the driving technique of the simulated two-wheeled vehicle. By providing a control means for making judgments, you can obtain the same operating feeling as driving on the actual road while looking at the display device, and judge the driving technique by comparing the driving operations of the simulated two-wheeled vehicle with road information. A simulated driving system for two-wheeled vehicles that can improve and test technology can be provided.
