Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for safely educating an automobile driving technique to a subject, more specifically, without using an actual automobile and road,
All the subjects can see how the driving operation of each subject is different from the preset model driving operation by providing the driving images to multiple subjects through the monitor. The present invention relates to a simulated driving device for learning for detecting and diagnosing with the same standard.

[0002]

2. Description of the Related Art Some training simulator driving devices for teaching a car driving technique without using an actual car are still proposed. FIG. 3 shows an example of the configuration, which is an excerpt of the technique disclosed in Japanese Patent Publication No. 63-59148. In FIG. 3, 1 is a simulated driver's seat,
2 is an NTSC standard monitor TV installed in the simulated driver's seat 1; 3 is driving operation devices (steering wheel, pedal, gear change lever, etc.) arranged in the simulated driver's seat 1 at almost the same positions as the actual vehicle, 4 Is a driver's seat control device for controlling the monitor television 2 and detecting the operation of each driving operation device 3 to diagnose and evaluate the operation contents, 5 is a communication line, 6 is a plurality of video players 6a, 6b, 6
, a video reproducing device for supplying the video signal reproduced by each video player to the monitor TV 2 of the simulated driver's seat 1 through the communication line 5, and 7 for controlling the video reproducing device 6 and performing the simulated driving. Reference numeral 8 denotes a system controller that collects the results of diagnosis and evaluation by the driver's seat controller 4 of the seat 1, and reference numeral 8 denotes an input device for instructing the progress of the training simulation simulator by the control of the system controller 7.

In this conventional device configuration, the actual running image of the road recorded in advance in each of the video players 6a, 6b, 6c, ... Is displayed on the screen of the monitor TV 2 of the simulated driver's seat 1, Further, the screen of the monitor TV 2 was a TV size with an aspect ratio of 3: 4, and its appropriate angle of view (viewing angle of image) was about 25 ° in the horizontal direction. Further, the sampling interval for detecting the operation of each driving operation device 3 performed by the subject on the road running video displayed on the screen of the monitor TV 2, that is, the detection interval of the driving operation content for diagnosis is 1/30 second. (See column 15, lines 5 and 6 of the above publication).

In such an apparatus configuration, when the input device 8 instructs the preparation for diagnosis under the control of the system control device 7, the system control device 7 instructs the video reproduction device 6 to reproduce the video, and the system control is performed. The device 7 instructs the driver's seat controller 4 of the simulated driver's seat 1 via the communication line 5 to prepare for diagnosis. As a result, the video reproduction device 6
, One of the plurality of video players 6a, 6b, 6c, ... Is activated, and the video signal reproduced by the video player is supplied to the monitor television 2 via the communication line 5.
A road driving image corresponding to the image signal is displayed on the screen.

Thereafter, by inputting the start of diagnosis from the input device 8 by the same operation as described above, a road traveling image for diagnosis is displayed on the screen of the monitor TV 2. The subject operates each driving operation device 3 in the simulated driver's seat 1 in accordance with the projected image for diagnosis. Driver's seat controller 4
Detects the operation of each driving operation device 3 performed by the subject, diagnoses the content of the operation, and evaluates based on a preset evaluation calculation formula.

[0006]

As described above, in the prior art, the screen image of the monitor TV 2 which uses a video image of a road actually taken and which has a normal screen size with an aspect ratio of 3: 4 is used. Since the road driving image is displayed on the vehicle, the image quality of the image presented to the subject is not so good, and the viewing angle of the image is limited to the range of about 25 ° in the horizontal direction.

Therefore, the information amount of the image presented to the subject is much smaller than the information amount obtained when the vehicle actually travels on the road (for example, the information on the rear field of view by the side mirror or the rearview mirror is not reflected on the screen. As a result, there is a problem in that there is a difference between the recognition obtained from the image and the recognition of the actual road driving environment. This is not preferable from the viewpoint of more realistic traffic safety education.

Further, the sampling interval for detecting the contents of the driving operation for diagnosis is relatively coarse at 1/30 seconds, so that sufficient diagnosis cannot always be performed depending on the traveling environment. For example, there are some inconveniences such as being unable to perform sufficient diagnosis on a sudden event of a pedestrian crossing when turning right or left, or a dangerous event such as a following vehicle when changing lanes, which is often experienced while driving an actual vehicle. there were.

For this reason, there is a problem that it is difficult to obtain reliability of the diagnostic result because the unrealistic part is included in the diagnostic result of the operation content of each driving operation device. Also,
In another conventional technique, there is an example in which an image is created by computer graphics and supplied to a monitor TV instead of using an actual road image, but in the case of an image by this computer graphics, Since it is a different and simplified video, there is a problem in the truthfulness, for example, even if it is a very dangerous scene in the actual traffic situation, it cannot be recognized as dangerous from the video.

The present invention has been made in view of the above-mentioned problems in the prior art. It improves the image quality of a video image necessary for diagnosis, detects the subject's driving operation details with respect to the video image, and in turn improves reliability. It is an object of the present invention to provide a simulated driving device for learning that can present a high diagnostic result.

[0011]

In order to solve the above-mentioned problems of the prior art, according to the present invention, each operation device necessary for driving, which is arranged by simulating an actual automobile, and mainly a road traveling image are displayed. At least one simulated driver's seat including a monitor TV for displaying, and a first arithmetic control unit for controlling the monitor TV and detecting the operation of each operation device to diagnose and evaluate the operation content, A video reproduction device connected to the first arithmetic control unit via a communication line and supplying a video signal to the monitor television via the communication line, and the first arithmetic control for controlling the video reproduction device. A central control unit having a second arithmetic and control unit for collecting the results of diagnosis and evaluation by the unit via the communication line, and the monitor TV has a screen for presenting a high-definition image, The video reproduction device reproduces a video signal corresponding to the high-definition video, and the first arithmetic control unit has an arithmetic processing speed adapted to process the high-definition video signal. A simulated driving device for learning is provided.

According to the configuration of the simulated driving system for teaching according to the present invention, since the monitor television for providing the road traveling information to the subject has the screen for presenting the high-definition image, the image necessary for the diagnosis is provided. In addition to improving the image quality, the screen size with an aspect ratio of 9:16 allows the horizontal angle of view to be larger than the conventional type (about 25 °) (about 42 °), and the actual viewing angle. (About 40 ° -45 °)
Can be almost the same as.

As a result, it is possible to present the subject with an image having substantially the same amount of information as that obtained when the vehicle actually travels on the road, and the difference between the recognition obtained from the image and the recognition of the actual road driving environment can be calculated. It can be virtually eliminated. This greatly contributes to the realization of realistic traffic safety education. Further, since the first arithmetic and control unit for diagnosing and evaluating the driving operation contents performed by the subject in the simulated driver's seat has the arithmetic processing speed adapted to process the high definition video signal, It is possible to finely detect the driving operation content of the subject with respect to the video. This greatly contributes to the reliable presentation of diagnostic results.

Details of other structural features and operations of the present invention will be described using the embodiments described below with reference to the accompanying drawings.
