Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a driving school, etc.
The present invention relates to a device for photographing a trainee's driving situation from a plurality of angles with a camera and providing guidance.

[0002]

2. Description of the Related Art In a conventional driving school or driving school,
It was impossible to persuade the trainees to drive and the instructor to provide guidance afterwards. Check points for safe driving by the instructor are as follows: (1) Did you check the right door mirror when starting? (2) Did you check the left door mirror when turning left? (3) Is the accelerator released and the brakes depressed when checking forward before starting? (4) Does the speed comply with the speed limit? (5) Is the following distance correct? (6) Is the suspension observed? (7) When stopping, check the vehicle behind, turn on the brake lights, stop in earnest, and pull the brake lever. However, even if he later pointed out that he did not check the left and right when starting and did not pause, there was a person who argued that he did, and it was difficult for the instructor to point out and give guidance. In particular, people who have a long driving history and are retrained due to suspension, etc. are too used to driving in their own way, thinking that their driving method is good, and they can not objectively recognize their faults. there were.

[0003] An apparatus has been proposed in which a plurality of television cameras are attached to a training car to shoot a video so that the driving situation of the trainee during driving is copied and used for guidance later. With this conventional device, to view the front view seen from the windshield, the front of the trainee's face, the left and right feet to check the brake and accelerator operation status, and the speed on the multi screen The screen of the speedometer was projected on the screen.

[0004]

However, in such a conventional device, what kind of images are shown on the left and right door mirrors, which are one of the check points, and what kind of position the rear car is in, etc. Was not able to be confirmed, and there was a problem that guidance was not enough. The problem to be solved by the present invention is to provide a device capable of fully incorporating checkpoints for safe driving as information and providing total guidance.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a multi-video type car training apparatus according to the present invention has at least a camera for picking up an image reflected on left and right side mirrors of a training car and a foreground. A camera, a camera for imaging the face of the training car, and a camera for imaging the image reflected on the rearview mirror, and a recording device for recording the image captured by each camera as a multi-screen. Features. Furthermore, it is also possible to adopt a configuration in which a speedometer signal, an accelerator pedal signal, a brake pedal signal, and an inter-vehicle distance signal are taken in, and are recorded on the recording device as a multi-screen together with the video imaged by each camera.

A camera, 6 is a second camera for imaging the left door mirror, 7 is a third camera for imaging the rear, 8 is a fourth camera for imaging the driver, and 9 is a fifth camera for imaging the right door mirror. In this figure, the mirror for the instructor is not shown.

The first camera 5 is mounted on, for example, a dashboard, and the position is preferably set to a center position as much as possible, and the camera lens is set to a wide angle. The second and fifth cameras 6, 9 are mounted so as to be seen below the upper part of the door window, and the camera lens is wide-angle. The camera mirror is mounted below the door mirror. The third camera 7 is mounted around the front of the central room light, and the camera rearview mirror 4 is mounted on the front. Alternatively, it is mounted on the rear board. The camera lens is wide-angle. The fourth camera 8 is mounted on the right door ceiling side, and the camera lens is wide-angle. The camera mirror is a concave mirror.
