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

[0002]

2. Description of the Related Art A conventional driving training apparatus has three cameras installed near the driver's seat of an actual vehicle in order to give a realistic feeling to the scenery seen from the driver's seat. Shooting and recording the scenery on the right side in three directions while the vehicle is running at a constant speed, and when using it as a training device, it is 3
Using three playback devices, images are displayed on a three-sided screen arranged in front of the simulated vehicle in synchronization with each playback device.
In this case, as a method of simulating the speed of the vehicle, the reproduction speed is adjusted while the brightness of the image is not changed and the three surfaces have the same brightness.

However, in this method, since each surface is photographed by each camera with respect to the three-sided multi-image, the image when reproduced is different from that seen by human eyes, and high-speed running is required. Even if you simulate or simulate low speed running,
Since the images on the left and right screens are reproduced in exactly the same manner as the images on the front screen, the driver always has the same ratio in the field of view of the simulated vehicle, which has the drawback that the sense of speed is different from the actual one. In particular, the discomfort when simulating high-speed driving was remarkable.

[0004]

As a method of simulating the speed of a vehicle, when the reproduction speed is simply changed as in the conventional case, the relationship between the speed and the visual field is not satisfied, and as described above, there is a sense of realism in the speed. There was a problem that could not be obtained.

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 gives a driver a sense of speed and has a high training effect.

[0006]

In order to achieve the above object, the present invention reproduces a three-sided screen arranged 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-sided screen are provided, and a front view seen from the driver's seat is displayed on the screen as a three-sided multi-image, and a driver's acceleration / deceleration operation is performed. In the driving training simulator device for simulating the speed of the vehicle by changing the reproduction speed of the image projected on the screen according to the above, between the respective projectors projecting the left and right end screens of the three-sided multi-screen and the respective video players. It is connected through an RGB level converter, and the RGB level converter is used to connect the switch according to the speed of the vehicle. And adjusting the brightness of images displayed on the lean.

[0007]

In the driving training simulator apparatus of the present invention, as the vehicle speed increases, the levels of the RGB signals for the left and right screens of the three-sided multi-screen are lowered by the level converting means, so that Darken the image projected on the screen,
On the contrary, as the vehicle becomes slower, the levels of the RGB signals for the left and right screens of the three-sided multi-screen are raised by the level converting means to brighten the images projected on the left and right screens. go. By thus adjusting the image displayed on the screen, the driver's visual field can be forcibly narrowed or widened, so that the driver can feel the actual sense of speed.

Output a GB signal. Therefore, the RGB signals on the input side and the output side of the RGB level converter have a larger level difference as the vehicle speed increases, and the images displayed 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 between the light and darkness of is increasing. As a result, the driver's field of vision can be narrowed, and the driver can be given the feeling of accelerating.

Although the above description has been made on the case where the vehicle accelerates, on the contrary, when the vehicle decelerates, the images displayed by the projectors 5 and 7 become brighter.
Since the difference between the lightness and the darkness of the images on the screen 9 and the screens 8 and 10 becomes smaller, the driver's visual field can be gradually widened as the vehicle progresses, so that the driver feels that the vehicle is decelerating. be able to.

As described above, according to the present embodiment, when the vehicle is in the stopped state, the brightness of the multi-image on the three surfaces is made equal. Next, when simulating a state in which the vehicle speed is increased by the driver's acceleration operation, the images displayed on the left and right end screens of the three-sided multi-screen are darkened in correspondence with the reproduction speed of the image. Conversely, when simulating a state in which the vehicle speed is slowed down by the driver's deceleration operation, the images displayed on the left and right end screens of the three-sided multi-screen are made brighter in accordance with the reproduction speed of the image. . Furthermore, when simulating running at a constant speed, by maintaining the brightness of the image corresponding to that speed, it is possible to widen or narrow the driver's visual field and increase the sense of realism with respect to the speed of the vehicle.
