画面を見て他車位置を監視する必要はない。However, the conventional navigation device described above only displays the position of the other vehicle on the screen, and unless the user pays attention to the screen, the positional relationship between the own vehicle and the other vehicle cannot be known. The user frequently checks the screen, such as when the positional relationship between another vehicle and the own vehicle is constantly monitored, and there is a problem that driving safety decreases and fatigue increases when the user is a driver. For example,
When traveling with multiple cars with friends, I always want to monitor the position of other cars, but whether a car strayed from the group came out,
Further, it is sufficient to check the position of the other vehicle in detail only when approaching a stray car (or a waiting car), and it is not necessary to constantly monitor the position of the other car by looking at the screen.

きる。Next, the operation of monitoring the position of another vehicle will be described with reference to FIGS. 2 and 3. As shown in FIG. 2, when the own vehicle 201 constantly monitors the position of the other vehicle 202, the current position P 1 of the other vehicle 202 on the road 203 that is periodically acquired by the other vehicle communication unit 110 through the mobile phone line. Can be output to the map display control unit 107 to display a map centering on the other vehicle 202 to notify the user of the location of the other vehicle 202. If you just want to check if there are any cars that are out of the group or if the stray cars have reached the vicinity of your car, such as when traveling with multiple cars with friends, the user can input in advance. At 106, a warning sound boundary radius D for setting the warning sound boundary 204 is input. The inter-vehicle distance determination unit 111 causes the speaker 112 to output a warning sound when the other vehicle 202 crosses the warning sound boundary 204, and therefore the user uses this warning sound as a signal.
It is only necessary to switch to the map display centered on 02, the frequency of watching the screen for confirming the position of the other vehicle is reduced, the user's fatigue can be reduced, and the driving safety can be improved.

After initial setting (step 301), other vehicle communication unit 1
Every time the current position P 1 of the other vehicle 202 is acquired at 10 (step 302), the inter-vehicle distance d from the current position P 0 of the own vehicle 201 is obtained (step 303). If the current position P 1 'of the other vehicle 202 received last time is inside the warning sound boundary 204 and the current position P 1 of this time is outside the warning sound boundary 204 (step 306), the other vehicle 202 It is determined that the user has escaped to the outside of the warning sound boundary 204, and a warning sound for escape is output (step 307). Further, the current position P 1 'of the other vehicle 202 received last time is outside the warning sound boundary 204, and the current position P 1 of this time is the warning sound boundary 2
If it is on the inner side of 04 (step 309), the other vehicle 2
It is determined that 02 has entered the inside of the warning sound boundary 204, and a warning sound for entry different from that for escape is output (step 310). At this time, when the other vehicle 202 is running near the warning sound boundary 204, it is noisy that unnecessary rush warning sound and escape warning sound are alternately and frequently output. The next warning sound is not output until the inter-vehicle distance d changes by a predetermined value α or more (steps 304, 305). By performing the above processing for each vehicle, a plurality of vehicles can be monitored simultaneously.

果を有する。As is apparent from the above embodiment, the present invention is provided with the positional relation output means for outputting a warning sound according to the inter-vehicle distance between the own vehicle and another vehicle, and at the moment when the inter-vehicle distance deviates from the predetermined value. Alternatively, a warning sound is output at the moment when the vehicle enters the predetermined value, and it is possible to easily know whether another vehicle enters or leaves the predetermined range of the own vehicle. Therefore, when it is desired to check whether or not another vehicle is in the vicinity of the own vehicle, it is possible to reduce the frequency of gazing at the display screen, which has the effect of reducing user fatigue and improving driving safety.
