DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving training simulator for improving the skill of driving a vehicle.

[0002]

2. Description of the Related Art In a conventional driving training apparatus, three cameras are placed in the vicinity of a driver's seat of an actual vehicle in order to give a sense of reality to a scene in front of the driver's seat. When shooting and recording the scenery in the three directions on the right side while running the vehicle at a constant speed, 3
Using three playback devices, the images are projected on three screens arranged in front of the simulation vehicle while synchronizing the playback devices.
In this case, as a method of simulating the speed of the vehicle, a method of adjusting the reproduction speed while maintaining the same brightness on all three surfaces without changing the brightness of the image has been used.

However, in this method, since each surface is photographed with respect to each of the three multi-images by the respective cameras, the reproduced image is different from what is seen by human eyes, and the high-speed running is different. If you simulate or simulate low-speed driving,
Since the images on the screens on the left and right sides are reproduced exactly in the same way as the images on the front screen, they always enter the driver's field of view of the simulated vehicle at the same ratio, and there is a disadvantage that the sense of speed is different from the actual one. In particular, the feeling of strangeness when simulating high-speed running was remarkable.

[0004]

If a method of simulating the speed of a vehicle is performed only by changing the reproduction speed as in the prior art, the relationship between the speed and the visual field is not satisfied. There was a problem that can not be obtained.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a driving training simulator apparatus which allows a driver to feel a sense of speed and has a high training effect.

[0006]

In order to achieve the above object, the present invention reproduces three screens disposed in front of a simulated vehicle and a scene in front of the vehicle and outputs them as RGB signals. A video player and a projector for inputting the RGB signals and projecting an image on the three screens, projecting a front view seen from a driver's seat as a multi-image of three screens on the screen, and performing acceleration / deceleration operation of the driver. In a driving training simulator apparatus that simulates the speed of a vehicle by changing the playback speed of an image projected on a screen according to the following, between each projector that projects the left and right end screens of the three multi-screens and each video player Connected via an RGB level converter, and the RGB level converter according to the speed of the vehicle. And adjusting the brightness of images displayed on the lean.

[0007]

In the driving training simulator of the present invention, the level conversion means lowers the levels of the RGB signals for the screens on the left and right sides of the three-screen multi-screen as the speed of the vehicle increases, so that the left and right sides are reduced. Darkens the image projected on the screen,
Conversely, as the speed of the vehicle decreases, the level of the RGB signals for the left and right screens on the left and right sides of the three-screen multi-screen is increased by the level conversion means, thereby brightening the images projected on the left and right screens. go. By adjusting the image projected on the screen in this way, the driver's field of view can be forcibly narrowed or widened, so that the driver can feel a sense of actual speed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram of a driving training simulator apparatus according to one embodiment of the present invention. In the figure,
The driving training simulator device of the present embodiment includes a computer 1 and:
Video players 2, 3, and 4 each containing a disk as a storage medium for video data;
, Projectors 5, 6, and 7, screens 8, 9, 10 corresponding to the projectors 5, 6, 7, and video players 2, 4 and a projector 5 for projecting images on the left and right screens 8, 10. , 6 and RGB level converters 11 and 12 and a cab 13.

FIG. 2 is a flowchart showing the processing contents of the computer 1, and FIG. 3 is a data table of the vehicle speed, the reproduction speed of the video player and the RGB signal levels stored in the computer 1.

Next, the operation of this embodiment will be described with reference to FIGS. When the computer 1 receives the training start signal from the driver's cab 13, the computer 1 recognizes the fact in the process 101 and executes the process 102
Output the reproduction start address of the disc as the video data storage medium to the video players 2, 3, and 4. After that, when the computer 1 inputs an acceleration command from the cab 13, the computer 1 executes processing 1
In step 03, the fact is recognized, and in step 104, the speed V of the vehicle is obtained at an acceleration corresponding to the vehicle performance. In step 105, the data table shown in FIG.
Is obtained, and the reproduction speed PV and the RGB level CL are obtained, and output to the video players 2, 3, and 4 and the RGB level converters 11 and 12, respectively. Video players 2, 3, 4
Inputs the reproduction start address and the reproduction speed from the computer 1, sequentially reads the video data from the disk at a frequency corresponding to the reproduction speed PV starting from the reproduction start address, reproduces the video data, and outputs it as an RGB signal to the outside.

[0011] The read address of the disk is
After reading is started only once at the beginning, the video player 2, 3, 4 itself reproduces the reproduction speed PV.
The video data is sequentially updated each time the video data is read. The RGB level converters 11 and 12 receive the RGB signals output from the video players 2 and 3 and convert the RGB signals to a level corresponding to the RGB level CL specified by the computer 1.
R after converting the B signal and converting it to projectors 5 and 7
Outputs a GB signal. Therefore, the level difference between the RGB signals on the input side and the output side of the RGB level converter increases as the vehicle speed increases, and the images projected by the projectors 5 and 7 become darker, and the images on the screen 9 and the screens 8 and 10 become darker. The difference in light and darkness becomes larger. As a result, the driver's field of view can be narrowed, so that the driver can have a feeling of accelerating.

In the above, the case where the vehicle accelerates has been described. Conversely, when the vehicle decelerates, the images projected by the projectors 5 and 7 become brighter.
Since the difference between the brightness of the image on the screen 9 and the brightness of the image on the screens 8 and 10 becomes smaller, the driver's visual field can be gradually expanded with the progress of the vehicle, so that the driver feels that the vehicle is decelerating. be able to.

As described above, according to this embodiment, when the vehicle is at a standstill, the brightness of the multi-images on the three surfaces is made equal. Next, when simulating a situation in which the speed of the vehicle is increased by the driver's acceleration operation, the images projected on the left and right end screens of the three-screen multi-screen are darkened in accordance with the reproduction speed of the images. Conversely, when simulating a situation in which the speed of the vehicle is slowed down by the driver's deceleration operation, the video projected on the left and right end screens of the three-screen multi-screen is brightened in accordance with the playback speed of the video. . Furthermore, when simulating driving at a constant speed, it is possible to increase or reduce the driver's field of view by maintaining the brightness of the image corresponding to that speed, thereby increasing the sense of reality with respect to the speed of the vehicle. Become.

[0014]

As described above, according to the present invention, by forcibly changing the field of view of the scene ahead of the driver according to the speed of the vehicle, it is possible to give the driver a real feeling of speed. It is possible to provide a driving training simulator device in which a greater effect can be expected.
