DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device that allows a trainee to experience the visual recognition characteristics of a driver who drives a car.

[0002]

2. Description of the Related Art Conventionally, as a part of a car lesson, a simulator for driving while watching a monitor screen indoors has been used to teach various precautions in driving a car through a simulated experience. By the way, in particular, when driving under poor visibility conditions such as at night, visibility characteristics different from those at daytime occur, and the illusion phenomenon and the like make the driver misjudgment and have become a major cause of traffic accidents. By the way, according to the 1994 Road Safety White Paper, the fatal accident rate (the number of fatal accidents per thousand accidents) at night was 25.7, which is about three times higher than 8.8 during the day. The white paper proposes that "immediate measures against accidents at night are urgently needed" and that the newcomers should focus on improving nighttime driving guidance for beginners. However, a device using a monitor screen is not suitable for simulated experiences such as an illusion phenomenon that needs to show depth. Therefore, this type of training was performed outdoors at night using an actual vehicle.

[0003] For such a training using a real vehicle, a film in which only the range where the headlight reaches can be kept transparent and the light transmittance is reduced in other cases, so that the night vision can be learned even in the daytime. Japanese Unexamined Utility Model Publication No. Hei 6-47962 discloses a device that is attached to a windshield of an actual vehicle to simulate night vision. However, the experience by the above means is limited to confirming the visual field range of night vision at best, and there is annoyance of sticking the shielding film for visual field adjustment to the windshield, and the visual characteristics such as pedestrian disappearance phenomenon at night. Cannot be experienced. In the first place, there is no other way to learn about the visual characteristics described above with a real car than at night, and it is also impractical to wait for various phenomena to occur by accident. Is
The oncoming vehicle and the pedestrian are arranged as appropriate, and setting is made in accordance with the conditions, but a great deal of labor is required for that.

[0004]

Therefore, there has been a demand for a device capable of easily learning these simulated experiences indoors, but Japanese Utility Model Laid-Open No. 6-43660 has been proposed as an indoor device. This device can be used to simulate a driving environment indoors at night. By the way,
A road surface is provided in a box having a light-shielding property, and an object to be tested is arranged on the road surface. What can be experienced by this is "a group of dolls which can be installed in the box and are dressed in different colors of clothing. In addition to showing the illusion of distance due to the difference in visibility due to the difference in the height of the headlights of a set of car models, and at best the visibility of traffic signs and road markings, etc. In addition to the limited contents that can be experienced, due to the structure of the box, it is necessary to secure the light blocking effect by configuring the viewing opening to look through a small peephole, and through the large windshield It is far from the actual driving situation that will be experienced. On the other hand, in a driving environment simulation experience device, it is preferable to be able to express a certain degree of perspective. For this purpose, a device having a long front and rear length is required, and the entire device becomes large. In the Japanese Unexamined Utility Model Publication No. Hei 6-43660, measures are taken to avoid enlargement by using an eyepiece so as to secure a perspective, but from this point of view the opening for visual recognition is small. As a result, it was impossible to simulate a large field of view equivalent to the windshield of an actual vehicle.

[0005] Therefore, in the conventional attempts, many trainees cannot easily have a simulated experience, or they can only experience a limited range. In addition, the indoor apparatus according to the prior art additionally has a problem that it lacks a sense of reality at the time of visual recognition, does not have an operation unit in which operation means are concentrated, and is not easy to use.

[0006]

Two boards are provided, one on top of the other, and a mirror image of the road surface shown on the lower partition plate is combined with a mirror plate on the front of the partition plate so that the mirror image of the road surface shown on the upper partition plate can be seen on an extension of the road surface shown on the upper partition plate. , Shortening the length of the box while maintaining the light shielding inside the box, and
A wide opening is provided.

In this apparatus, an oncoming vehicle traveling position is provided on a road surface on a partition plate, a light source unit corresponding to a headlight of the oncoming vehicle at the traveling position is provided, and an object to be tested is arranged in front of the light source unit. In addition, it is possible to simulate how the visibility of the test object changes depending on the presence of the light source.

Further, by changing the irradiation angle of the light from the light source unit corresponding to the headlight of the oncoming vehicle in at least two steps, the user can simulate the dazzling state when directly viewing the upward beam of the oncoming vehicle. You can do it.

[0010] Further, by providing a mechanism capable of moving at least one of the position of the test object or the position of the light source unit corresponding to the oncoming vehicle, a change in the visibility of the test object and the opposition when making a right turn from a straight road. This makes it possible to simulate at least one of the illusion phenomena of the inter-vehicle distance to the vehicle.

Furthermore, the test object is composed of a pedestrian consisting of at least a single doll and a pedestrian group consisting of a plurality of dolls each wearing clothing of different colors, and the test object can be appropriately replaced on the road surface. A mechanism can be provided.

Further, at least two light sources, an incandescent lamp and a black light, are provided in the box, and the inside of the box is drawn by using a fluorescent paint which reacts to the black light. By performing nighttime and variably controlling the illuminance of at least one of these light sources, it is possible to simulate the visual recognition characteristics in various time zones such as a twilight state.

In addition, a raindrop adhesion state expression plate for indicating the field of view of the windshield in rainy weather can be provided in the viewing opening of the box so that the user can experience the visual recognition characteristics in rainy weather.

Further, the state of the wiping portion wiped off by the wiper and the non-wiping portion can be reproduced on the raindrop adhesion state expression plate.

Can be simulated.

Further, the operation mechanism of the visual characteristic simulating device can be provided separately from the box.

[0021]

According to the present invention, by adopting the above-mentioned structure, the position where the test object and the like are disposed is partitioned by the partition plate, so that the invasion of light from the viewing opening is sufficiently reduced. Since it is located at a position deeper than the partition plate inside the box body (a position near the base end as viewed from outside the box body), it is possible to sufficiently provide the reproduction of the driving environment at night. In addition, the upper and lower partition plates are two upper and lower plates, and the test object arranged on the lower partition plate can be visually recognized as a mirror image reflected by the mirror plate at a position on the extension of the upper partition plate. By rendering the road surface drawn on the side partition plate in perspective, it is possible to have a necessary sense of distance, and as described above, it can be provided as it is to reproduce the driving environment at night as it is In combination with this, the size of the device can be reduced and the size of the opening for viewing can be made large enough to be regarded as a windshield of an actual vehicle.

Therefore, in the apparatus of the present invention, the realization of a training environment with a sense of reality can be provided by the realization of a large opening for visual recognition that can be regarded as a windshield.
The length of the box in the longitudinal direction is shortened, making the entire device compact, reducing the installation burden and saving space. Furthermore, despite the space-saving and compact box, a sense of perspective is achieved. Long straight roads with long roads were reproduced, and it was possible to simulate the visual characteristics with a sense of realism. In this way, the trainee can learn the simulated experience of the visibility characteristics in various driving environments simply by sitting indoors in a chair in front of the box.
