By doing so, in the present embodiment, when the instructor monitors the driving condition of the trainee from the monitoring room shown in FIG.
Since the current situation of the training vehicle itself can be accurately grasped, it is possible to provide accurate guidance on the operation side of the training vehicle. (First Embodiment) The operation of the configuration of the first embodiment will be described below, and the effect of the car training apparatus of the present invention will be described. In the first embodiment, a trainee rides alone on a training vehicle and runs on a course, and an instructor provides training guidance in a monitoring room. In addition, the instructor can actually provide training guidance while simultaneously monitoring two or three training vehicles, but here, for convenience, one training vehicle will be used and one instructor will provide training. I do. The instructor can monitor each part by the cameras 1 to 8 while watching the screen of the television 23 in the monitoring room, and visually recognize the current state of the training vehicle by the detecting unit 9. At that time, if necessary, by operating the operation unit 25,
The monitor and the video of the television 23 in the monitoring room are switched, and the zoom-in or zoom-out operation of the cameras 1 to 8 in the training vehicle is performed to monitor the surroundings, the expression of the trainee, and the operation of the limbs. Then, appropriate instructions and cautions are given to the driving situation of the trainee being monitored. In the unlikely event that the instructor feels dangerous, the operation unit 25 can turn off the drive ignition key to stop the engine. Once the instructor turns off the drive ignition key, the trainee cannot restart the engine while the timer is set. Also, since the video (including the status display) projected on the television 23 is connected to the external output terminal of the television 23, the video deck 24 is recorded during the training and played back after the training. Can provide more detailed guidance. The video recorded in this manner is
It can be recorded and stored for each individual as needed. Then, by lending the result of the training to the desired trainee as reference material for preparation and review, the training effect can be further enhanced. Although omitted in the configuration described above,
The voice of the instructor's instruction and caution from the monitoring room and the voice of the trainee responding to it may be transmitted using the current training radio of the current wireless guidance device, but one of the cameras 1 to 8 has a built-in microphone. By using the model, single transmission and simultaneous transmission are possible, and the instructor can use the current training radio, and the trainee can use the two-way simultaneous communication system as TV audio. Further, as the operation unit 25, each one set to a different frequency for each training vehicle may be used, but one operation unit 25 can correspond to each training vehicle. You may do so. That is, if the transmission frequency is configured to be switchable for a plurality of channels and the operation unit 25 is configured to be able to transmit in each channel, a plurality of training cars can be operated with one operation unit 25. (Second Embodiment) Next, a second embodiment employing the present invention will be described. The instructor rides on the training vehicle during the training course or on-the-spot training on the road, and looks at all the images of the cameras 1 to 8 projected on the television 11 and the situation of the training vehicle by the detection unit 9. It is possible to provide guidance and to record the video projected on the television 11 on the video deck 12. The instructor switches the screen and the image of the television 11 by operating the remote controller R as needed, or zooms in or out of the cameras 1 to 8 in the training car to change the screen of the television 11. Give instructions and guidance while watching the actual driving situation. In the unlikely event that the instructor feels dangerous, the remote control R can be used to turn off the drive ignition key to stop the engine. As in the first embodiment, when the instructor once turns off the drive ignition key, the trainee may not be able to restart the engine while the timer is set. In the present embodiment, the operation status recorded on the video tape of the video deck 12 is reproduced on the television 11 as necessary, after the training is completed, and specific advice is given to the trainee based on the video. At this time, if it is difficult to see the screen of the television 11 due to direct sunlight, it is sufficient to remove only the VCR 12 and the television 11 and reproduce the image at a position not exposed to direct sunlight. In addition, by lending this videotape to trainees as reference material for preparation and review, the training effect can be further enhanced. Therefore, also in the second embodiment, a plurality of images can be viewed simultaneously on the same screen without switching the screen, and the situation of the training vehicle can be always grasped on the same screen. The same effect as in the first embodiment can be obtained, and the video projected on the television 11 can be recorded on the video deck 12 and reproduced after the training, so that more detailed instruction can be provided. In particular, according to the present invention, the face (line of sight) of the trainee is trained by the camera 3, the steering wheel is trained by the camera 4, the left front of the train car is trained by the camera 5, the right front of the train car is trained by the camera 6, and the camera 7 is trained by the camera 7. Since the camera 8 captures the right rear of the training vehicle from the left rear of the vehicle, it is possible to visually recognize, on a single screen, parts that have conventionally been difficult for the instructor (and the trainee) to confirm. The video division unit 10A controls the television 1
Since the images of the cameras 1 to 8 in 1 (television 23) can be arbitrarily selected and laid out in one screen, it is not necessary to switch the screens in a complicated manner. In addition, by providing the acceleration sensor 9A and displaying the detection status on the television 11 (television 23) by the status display unit 10C, the guidance of acceleration / deceleration, which has been conventionally taught in a bodily sense, is concretely and more numerically. You will be able to provide detailed guidance. As described above, in the car training apparatus of the present invention, four of the plurality of video cameras are provided so as to show the periphery of the front tire and the rear tire. The situation around the tires of the training vehicle, which has been confirmed by the naked eye, can be checked all at once in the training vehicle. In addition, since the acceleration sensor for detecting the acceleration of the training vehicle is provided, acceleration / deceleration, which had conventionally been instructed by experience, can be instructed more specifically and in detail by numerical values. Then, an image taken by a plurality of video cameras mounted on a training car running in the training course is divided into a plurality of arbitrarily selected images on one screen by a video dividing unit, and the images are simultaneously displayed. Instructors can keep track of everything without having to switch screens,
Therefore, appropriate guidance can be provided. Also, the instructor can monitor the behavior of the training vehicle as a whole by simply monitoring the screen with the status display section, and can surely recognize dangerous situations that the trainees and instructors tend to overlook, so that more appropriate and reliable guidance can be provided. I can do it.
