Only the camera ON position marker 33 is displayed on the screen.
And In this way, all the points that the driver needs
When the registration is completed, the vehicle position detecting device 21 is operated to
When the map information is displayed on the display 5, it is shown in FIG.
Camera ON position marker for each registered point on the map screen
33 will be displayed. Fig. 5 shows the vehicle at point A
Camera ON position registration is not performed at points B, C and E while running.
It is shown that it is. 34 is a vehicle position marker
is there. Next, the imaging device 11 is controlled by the control device 25.
Automatically activates and monitors the side of the vehicle on the display 5
The operation for displaying an image will be described with reference to the flowchart of FIG.
This will be described with reference to the timing chart of FIG. vehicle
The initial settings for operating the position detection device 21 include:
The image switching circuit 25a receives a navigation signal from the vehicle position detecting device 21.
And display it on the display 5
(Steps S1 and S2). This display 5

An active signal is sent from the OR circuit 25b to the AND circuit 25d.
Input (branch to YES side in step S3). However
However, even if the driver approaches point B,
Judging that there is still a distance, slowly slow down the vehicle speed,
The actual vehicle speed detected by the vehicle speed sensor 24 is higher than 10 km / h
While the vehicle speed is large, the vehicle speed determination circuit 25c is connected to the AND circuit 25d.
Does not output an active signal (to the NO side in step S5).
Branch). Therefore, the vehicle position detection device 21 does not
Although the camera automatic ON signal SCA is input,
Ray 5 still has the navigation video signal SN
The display 5 is provided as a signal SD.
(Steps S3, S5, S1,
S2). When the vehicle approaches the point B further, the driver
Until the vehicle speed drops below 10km / h to stop once
When dropped, the vehicle speed determination circuit 25c ANDs the vehicle speed signal SV.
Output to the circuit 25d (YE in step S5).
(Branch to S side), AND circuit 25d is connected to OR circuit 25b
And the vehicle speed signal S from the vehicle speed determination circuit 25c.

Then, the vehicle speed determination circuit 25c stops outputting the vehicle speed signal SV.
The AND circuit 25d also outputs the camera video display signal SCO.
The image switching circuit 25a stops the imaging device 11
Stop, and the navigation image from the vehicle position detection device 21
Switch to image signal SN and display on display 5
(Steps S3, S5, S1, S2). Further, the navigation shown in FIG.
On the video display screen, go through point A-point B-point C
When trying to go to a point, this point D
It is a point where ON location is not registered, but from the road condition
If the driver determines that side monitoring is necessary
In this case, the camera switch 23 is manually operated (step S4).
Branch to YES). In the event of manual operation in this way
Is a camera manual ON signal SCM from the camera switch 23.
Is input to the OR circuit 25b and detected by the vehicle speed sensor 24.
If the actual vehicle speed is 10 km / h or less,
The vehicle speed determination circuit 25c outputs the vehicle speed signal SV,
D circuit 25d switches camera video display signal SCO to video switching circuit
To the road 25a to activate the imaging device 11 and
Displaying the camera video signal SC on the display 5
(Steps S5, S6, S7). The above-described series of operations are described in the timing chart of FIG.
Explanation will be made based on the chart. Where the driver is at his discretion
Start slowing down the vehicle speed at timing t1 to reach the point

CO is no longer output, and the video switching circuit 25a
The navigation video signal SN from the detection device 21 is
This is displayed on the display 5. The driver
If you forget to turn off the camera switch 23,
The vehicle starts accelerating after passing, and the actual vehicle speed becomes the vehicle speed signal ON threshold.
Exceeds the vehicle speed signal from the vehicle speed determination circuit 25c.
SV is not output, and the camera
The image display signal SCO is not output, and the video switching circuit 25
a is a navigation video signal from the vehicle position detecting device 21;
Switch to the SN and display it on the display 5 again
The side monitoring video is displayed on the display 5 and continues.
I won't go. In the map screen shown in FIG.
Vehicle reaches point E from point A via BCD point
Is displayed at points B and C where you passed when taking such a path
The camera automatic ON position marker 33 was automatically erased.
It is. Thus, the vehicle side monitoring system of the first embodiment is described.
The visual device superimposes on the map information of the vehicle position detecting device 21.
By registering the side monitoring points,
When the vehicle 21 comes close to the registration point and the vehicle speed
When the speed is reduced to a predetermined speed or less, the imaging device 1 is automatically
