it should be noted that, referring to fig. 2, fig. 2 is a flowchart of another method for constructing a fleet communication network according to an embodiment of the present application, as shown in fig. 2, the step of determining a master node in a fleet includes:
s201, in the motorcade, aiming at each vehicle in the motorcade, determining the vehicles which are in two-point communication with the vehicle in the motorcade as direct communication vehicles, and determining the number of the direct communication vehicles corresponding to the vehicles;
s202, determining the vehicle with the largest number of the direct communication vehicles as a vehicle to be selected among the numbers of the direct communication vehicles corresponding to each vehicle, and determining whether the vehicle to be selected is unique;
s203, if the vehicle to be selected is unique, determining the vehicle to be selected as a main node;
and S204, if the target distance of each vehicle to be selected is not unique, determining the target distance of the vehicle to be selected, and determining the vehicle to be selected with the minimum target distance as a main node in the target distance of each vehicle to be selected.

and S1033, determining the delay time with the largest value as the target network delay of the network formed by the main node and the relay node in the delay time corresponding to each vehicle.
In the step, whether the newly constructed network is acceptable or not, and communication evaluation is required; specifically, the newly decided master node sends an Echo instruction (Echo instruction) to all nodes in the network, and all vehicles in the network respond with the highest priority; counting the delay time of all Echo instructions by the master node, and selecting the maximum value (namely the target network delay); if the target network delay is within the preset threshold range, completing the network construction confirmation; if the preset threshold value is exceeded, repeating the previous network construction flow again until the set maximum try number is reached; here, the preset threshold value may be a constant preset according to historical experience or experimental data. In the networking process, the networking condition of the network and the network confirmation link based on the target network delay are increased, and the relatively static network scheme is used for replacing the frequent dynamic networking process, so that the precious energy consumption of vehicles is saved, the vehicle performance is improved, and the communication efficiency and the communication quality of a vehicle team are also improved.
The embodiment of the application provides a method for constructing a vehicle team communication network, which comprises the following steps: acquiring networking parameters of all vehicles in a motorcade in a local area network, and determining whether the motorcade performs networking or not based on the networking parameters of each vehicle; if yes, determining a main node and a relay node in the motorcade; and obtaining target network delay of a network formed by the main node and the relay node based on the main node and the relay node, determining whether the target network delay is smaller than or equal to a preset threshold value, and if yes, determining the network formed by the main node and the relay node as a communication network of a vehicle team.
