FIG. 5 shows the arrangement of the fixed and turning video cameras in the second embodiment of the driving training device of the present invention.

First Embodiment In FIG. 1, reference numeral 1 denotes a training vehicle, and 2 denotes a monitoring room (building). Here, both the training vehicle 1 and the monitoring room 2 are shown for only one vehicle. Of course, there are a plurality of training cars 1 above.

In the training vehicle 1, for example, fixed video cameras 3a and 3b are respectively attached to a dash board 1a and a rear board 1b, and a turning video camera 4a is attached to an electric pan head 1d provided in a passenger seat 1c, for example. The fixed video camera 3a captures the front field of view, the fixed video camera 3b captures the rear field of view, and the turning video camera 4a can rotate up, down, left and right to capture the student's driving situation, feet, and surrounding fields. I am trying to.

The training car 1 has a video transmitter 6 that converts video signals captured by the fixed video cameras 3 a and 3 b and the turning video camera 4 a into radio frequency signals and transmits the radio frequency signals from the transmission antennas 5, 5 and 5. And transmits the captured video signal to the monitoring room 2. Here, the video transmitter 6 transmits a radio frequency signal in the UHF band, and transmits at different frequencies (channels).

The training vehicle 1 is provided with a remote control signal receiver 7 for receiving a remote control signal from the operation of the monitoring room 2. The remote control signal receiver 7 is provided with a receiving antenna 8 for receiving the signal. The output is input to the control device 9. The control device 9 performs vertical and horizontal turning driving of the electric pan head 1d, and performs OFF control of a driving ignition key 11 of an engine driving circuit 10 of the training vehicle 1 via a timer circuit 12. .

Here, the timer circuit 12 is provided to prevent the trainee from immediately restarting the engine when the drive ignition key 11 is turned off. When the drive ignition key 11 is turned on after about 10 to 30 seconds, the engine can be started. Reference numeral 13 denotes a power supply for a vehicle.

In order to detect and output the behavior of the training vehicle 1, the training vehicle 1 includes, for example, a speed detector 14 a that detects the speed of the training vehicle 1 in conjunction with a speedometer, and a direction indicator. A turn signal detector 14b for detecting the turning on or off of the turn signal in the training vehicle 1 in conjunction with the vehicle, a gear detector 14c for detecting the gear shift situation, and a brake detector for detecting that the brake has been applied. 14d, a distance detecting unit 14e for detecting a distance to a lateral or rear obstacle, and a seat belt detecting unit 14f for detecting whether or not a seat belt is worn. I have it.

The detection result signal from the detection device 14 is transmitted to the monitoring room 2 on a band different from the video signal in the UHF signal band output from the transmission antennas 5, 5, 5, for example. I have. Of course, another antenna may be used to transmit only the detection signal from another antenna.

Next, the monitoring room 2 has a plurality of UHF receiving antennas 21 for receiving signals from the transmitting antennas 5, 5 and 5 of the training car 1, and video signals received via the direct-type booster 22. And a distributor 23 to which a signal of a detection result from the detection device 14 is inputted, and a book connected to the distributor 23 for displaying a plurality of images of each of the training cars 1 received at a time by dividing the screen. It comprises a video dividing device 24 according to the invented configuration, a status display device 25 for displaying the status of the training vehicle 1 by, for example, subtitles based on a detection result signal, and a television 26 for displaying video.

In this case, the video dividing device 24 divides the video from the fixed video cameras 3 a and 3 b and the turning video camera 4 a of the training vehicle 1 into three vertical sections as shown in FIG. It is projected on 26 at a time.

In FIG. 2, an image of the front of the training vehicle 1 with the stationary video camera 3a is displayed at the top of the screen of the television 26, and the training vehicle 1 with the stationary video camera 3b is displayed at the center of the screen of the television 26. An image of the rear of the camera is displayed, and an image of, for example, the periphery of the handle, which is captured by the turning video camera 4a, is displayed at the bottom of the screen of the television 26.

In this way, the instructor in the monitoring room 2 does not need to perform the switching operation of a plurality of images, and therefore monitors the images from the fixed video cameras 3a and 3b and the turning video camera 4a all at once. Therefore, the entire situation of the training vehicle 1 can be constantly monitored.

The status display device 25 is displayed on the screen of the television 26 based on the output of the detection device 14, for example, in the layout shown in FIG. In FIG. 2, the status display device 25 always displays the speed, for example, “40 KM / H” at the top center of the screen of the television 26 based on the output from the speed detection unit 14a.

The status display device 25 displays both at the center of the screen of the television 26 on both sides of the screen based on the output of the direction indicator detecting unit 14b, but displays an arrow “←” or “→” on the direction indicator. Displayed when is operated. The status display device 25 displays all the gears on the lower side of the center of the screen of the television 26 based on the output of the gear detection unit 14c, but always displays the gear shift position such as “BACK” or “PARK”. I do. The display of the gear shift position based on the gear detection unit 14c is not limited to the above, and may be displayed for each gear change from “1: low” to “5: top”.

The status display device 25 displays “BRAKE” at the bottom center of the screen of the television 26 based on the output from the brake detection unit 14 d when the brake is operated. The status display device 25 displays “← 1.5 m NEAR” at the bottom left of the screen of the television 26 when an obstacle approaches within 3.0 m on both sides and the rear based on the output from the distance detection unit 14 e. The direction and distance are displayed, such as "→ 1.5m NEAR" or "↓ 1.5m NEAR".

The status display device 25 displays “FASTEN SEATBELT” in the center of the screen of the television 26 based on the output of the seat belt detection unit 14f until the seat belt is worn.

In this way, in the present embodiment, when the instructor monitors the driving state of the trainee from the monitoring room 2, the situation around the training vehicle 1 is grasped and the training vehicle 1 itself is monitored. Since it is possible to accurately grasp the current situation, it is possible to provide accurate guidance on the operation of the training vehicle 1.

The monitoring room 2 includes a remote control transmitter 27 having a remote control operation unit 27 a and a transmission unit 27 b for converting a remote control signal into a radio frequency signal and transmitting the signal from a wireless transmission antenna 28. I have. Here, the remote control transmitter 27 transmits a radio frequency signal in the VHF band.

A plurality of receiving antennas 21 are installed in a driving school building with a different direction for each of the training vehicles 1 running on the course, and are radiated from the transmitting antennas 5, 5, and 5 of the training vehicle 1. Makes it easier to catch weak radio waves.

The splitter 23 to which a signal is input from the receiving antenna 21 is capable of distributing a plurality of channels (frequency) by a filter, and has a detecting device 14 that transmits in a band different from the video signal. It serves to separate the detection result signal from the video signal from the video signal. For example, if the number of channels is six, the fixed video cameras 3a and 3b and the turning video camera 4a use three channels for one training vehicle, so that two training vehicles 1 can be used. At this time, two televisions 26 are used.

The operation of the configuration of the first embodiment will be described below, and the effect of the car training device of the present invention will be described. In the first embodiment, a trainee rides alone on a training car 1 and runs on a course, and an instructor provides training guidance in a monitoring room 2. It is also possible for the trainer to actually provide training while simultaneously monitoring two or three training cars, but here, for convenience, one trainer 1 car and one trainer to train. Will be described.

The instructor can monitor the front, rear, left and right of the training vehicle 1 and visually recognize the current situation of the training vehicle 1 while watching the screen of one television 26. At this time, if necessary, the remote control transmitter 27 is used to perform upward and downward operations and left and right operations by turning the turning video camera 4a to monitor the surroundings, monitor the expression of the trainee, and monitor the operations of the limbs. I do. Then, give appropriate instructions and cautions to the driving situation of the trainee being monitored.

In the unlikely event that the trainer feels dangerous, the engine can be stopped by operating the remote control transmitter 27 to turn off the drive ignition key 11. Once the instructor turns off the drive ignition key 11, the trainee cannot restart the engine while the timer circuit 12 is set.

The images (including the status display) projected on the television 26 are recorded during the training by connecting a recording / reproducing device to the external output terminal of the television 26, and are reproduced after the training. Can provide more detailed guidance.

Also, the video recorded in this way can be recorded and stored for each individual as needed. By lending the results of the training to the desired trainees as reference materials for preparation and review, the training effect can be further enhanced.

The arrangement of the fixed video cameras 3a and 3b and the turning video camera 4a may be appropriately changed as shown in FIG. That is, in the state shown in FIG. 3, the fixed video camera 3a is fixed to the front right ceiling 1f near the windshield 1e of the training vehicle 1. On the other hand, the stationary video camera 3b is fixed to the front left ceiling 1f near the windshield 1e of the training vehicle 1.

The fixed video cameras 3c and 3d are installed so that they are almost at eye level when the training instructor sits on the passenger seat 1c. The turning video camera 4a is suspended by an electric pan head 1d fixed to a substantially central portion of the ceiling 1f of the body of the training vehicle 1 and operated by the remote control transmitter 27 of the monitoring room 2 as necessary. The monitoring of the student's feet and the rear is performed by turning the turning video camera 4a.

By arranging the fixed video cameras 3a and 3b and the turning video camera 4a in this way, while always monitoring the trainee's feet and the rear, the front monitoring at the time of turning left and right is wider and more. It can be done reliably.

Although omitted from the configuration described above, the voice of the instructor's instructions and cautions from the monitoring room 2 and the voice of the trainee who responds thereto can be transmitted by using the training radio of the current radio guidance device as it is. It is good, but by making either the fixed video camera 3a, 3b or the turning video camera 4a with a built-in microphone, independent transmission and simultaneous transmission are possible. Will allow simultaneous two-way communication as TV audio.

As the remote control transmitter 27, each remote control transmitter 27 set to a different frequency for each training car 1 may be used, but only one remote control transmitter 27 is used. You may make it correspond to each training car 1. In other words, if the transmission frequency is configured to be switchable for a plurality of channels and the remote control operation signal is configured to be transmitted on each channel, it is possible to operate a plurality of training vehicles 1 with one remote control transmitter 27. Become.

(Second Embodiment) Next, a second embodiment employing the present invention will be described. 4 and 5, a stationary video camera 3a for photographing the situation in front is fixed to the ceiling 1f near the windshield 1e, for example, and a stationary video camera 3b for photographing the situation behind is provided in the training vehicle 1. It is fixed to the rear board 1b.

Further, for example, a turning video camera 4a via an electric pan head 1d is installed in the passenger seat 1c, and this turning video camera 4a is turned by operating the electric pan head 1d. Is to capture not only the trainees' safety operation and shift operation, but also the surrounding conditions.

The fixed video cameras 3 a and 3 b and the turning video camera 4 a are connected to the video deck 30 via the status display device 25 connected to the video division device 24 and the detection device 14, which are the constituent elements of the present invention, respectively. ing.

Accordingly, the instructor rides on the training vehicle 1 during the training course or on-the-spot training on the road, and the fixed video cameras 3 a and 3 b and the turning video displayed on the television 26 connected to the VCR 30. It is possible to provide guidance by watching all the images of the camera 4a and the situation of the training vehicle 1 and to record the images shown on the television 26 on the VCR 30.

In this embodiment, if necessary, after the training, the driving status recorded on the video tape of the VCR 30 is reproduced on the television 26, and specific advice is given to the trainee based on the video. .

At this time, if it is difficult to view the screen of the television 26 due to direct sunlight, it is sufficient to remove only the video deck 30 and the television 26 and to play back at a position where direct sunlight does not reach. By renting 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 videos can be viewed simultaneously on the same screen without switching the screen, and the situation of the training car 1 can be always grasped on the same screen. The same effect as that of the first embodiment can be obtained, and the video projected on the television 26 can be recorded on the video deck 30 and reproduced after the lesson, so that more detailed guidance can be provided.

[0063]
