DESCRIPTION OF THE PREFERRED EMBODIMENTS (A) Outline of the Present Invention FIG. 1 is a schematic explanatory view of the present invention, in which two vehicles are touring, 1 is a destination, and 2 is a destination to a destination. The guidance route, 3a is a preceding vehicle, 3b is a following vehicle, and 4 is a traffic light. The vehicles 3a and 3b mutually notify their own vehicle positions by communication means such as a mobile phone. The navigation device of the preceding vehicle 3a calculates the distance L to the following vehicle 3b, monitors whether the distance L is longer than the set distance Ls due to waiting for a traffic light or the like, and outputs an alarm if it becomes longer than the set distance. The driver of the preceding vehicle recognizes that the following vehicle 3b has been delayed by the warning, selects the nearest facility that can be stopped by the navigation device, and connects the point to the meeting point W.
Determine p. Thereafter, the navigation device of the preceding vehicle 3a notifies the waiting point Wp to the navigation device of the following vehicle 3b, and the navigation device of each vehicle guides the route to the waiting point Wp.

The meeting point Wp is a facility that normally exists along the guide route 2. As shown in (1) and (3), the navigation device of each vehicle displays a guide route to the meeting point Wp. invite. Further, even when the meeting point Wp 'deviates from the guide route 2, (2),
As shown in (4), the navigation device of each vehicle displays and provides a guidance route to the meeting point Wp '. When the waiting points Wp and Wp 'move from their positions in the same manner as a normal passing point, the navigation device resumes route guidance toward the destination (or the next passing point).

[0007] The above is the case of two vehicles, but as shown in Fig. 2, even in the case of three or more vehicles, their own vehicle positions are notified to each other, and the distance between any two adjacent vehicles is longer than a set distance. Is output and an appropriate facility is set as a meeting point. That is, vehicle A and vehicle B transmit and receive each other's own vehicle position, vehicle B and vehicle C transmit and receive each other's own vehicle position, and vehicle C and vehicle A transmit and receive each other's own vehicle position. At this time, if the distance between any adjacent vehicles is equal to or greater than the predetermined distance L, the navigation device of the vehicle A that is the most forward (preceding) in the traveling direction searches for the nearest facility that can be stopped, The driver selects an appropriate facility from among them and sets that point as a meeting point. Then, the navigation device guides the route to the meeting point. When the waiting point is set, the waiting point is notified to other vehicles via the communication means, and the other vehicles B and C are route-guided toward the waiting point.

(B) Embodiment (a) Configuration FIG. 3 is a configuration diagram of a navigation device of the present invention provided with a communication device, 101 is a communication device, and 102 is a navigation device.
