Embodiment

Referring to Fig.1 and 2, the present invention provides a kind of more fleet's conflict method for early warning, including:

The default location information of notifying notified a little, obtains fleet's location information of more fleet Zhong Ge fleets in real time.Wherein, report is preset Believe point mode can there are many.For example, when the destination of more fleets is consistent, selection destination, which is used as, notifies a little;Alternatively, logical The driving path for obtaining each fleet is crossed, the conduct of the crosspoint between each path is chosen and notifies a little.As a preferred embodiment, originally Scheme is obtained according to the driving path of each fleet in each fleet's driving path preferably by obtaining the driving path of more fleets It is overlapped section.It is chosen and is notified a little according to overlapping section, obtain the location information of notifying notified a little.Wherein, notifying can be a little one It is a or multiple.During selection, crossing can be set as notifying a little according to overlapping section institute by crossing.It can also basis Section historical traffic amount information, using the transit point on normal congested link as notifying a little.The location information of fleet can pass through driving The mobile terminal of person or occupant obtain in real time, or the car-mounted terminal by being installed in fleet is obtained in real time.Preferably, Location information by obtaining the guide car of fleet is used as the location information of fleet.Wherein, guide car is the head vehicle of each fleet.
