The vehicle fleet is generally a plurality of vehicles with the same destination, the starting places of the vehicles may be different, but the destinations are the same, which generally occurs in the case of company tourism, dinner gathering and the like, in which case, due to the different navigation paths selected by the plurality of vehicles, the arrival time at the destination may be greatly different, for example, eating and playing at restaurant a at about 6 pm are better, but due to the path problem selected by one or two vehicles (due to the different congestion degrees of different paths), the difference of the arrival time is very large, so that the people arriving before need to wait for the arrival, and further the interest of tourism is influenced.
Referring to fig. 2, fig. 2 provides a vehicle fleet navigation method, which is shown in fig. 2 and is executed by the vehicle-mounted terminal shown in fig. 1, and which includes the following steps:
step S201, a vehicle-mounted terminal receives a team forming request of n other terminals, and after sending a team forming response to the n other terminals, a first team is formed with the n other terminals;
in an example, n is an integer of 2 or more.
Step S202, the vehicle-mounted terminal generates a first path between the current position and a first destination, and multicasts the first path in the first team; receiving n paths sent by other terminals, and displaying the first path and the n paths on a navigation map;
