S102, if yes, determining a main node and a relay node in the motorcade;
please refer to fig. 2, fig. 2 is a flowchart of another method for establishing a fleet communication network according to an embodiment of the present application, and as shown in fig. 2, the step of determining a master node in a fleet includes:
s201, in the motorcade, determining vehicles which carry out two-point communication with the vehicles in the motorcade as direct communication vehicles aiming at each vehicle in the motorcade, and determining the number of the direct communication vehicles corresponding to the vehicles;
s202, determining the vehicle with the largest number of direct communication vehicles as a vehicle to be selected in the number of 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 not, determining the target distance of each vehicle to be selected, and determining the vehicle to be selected with the minimum target distance as the master node in the target distance of each vehicle to be selected.
In this step, the election strategy of the master node is divided into two steps: firstly, the communication person wins the most nodes, if the node which can directly communicate with the most nodes in the network is only, the node is elected as the main node; secondly, the distance-optimal person wins, and if the number of direct communication nodes of a plurality of nodes in the network is the same, the master node is selected through distance optimization based on the steps from step S2041 to step S2045.

2. acquiring response time of the target vehicle obtained by inquiring returned after the other vehicles in the fleet receive the instruction;
3. and determining the vehicle corresponding to the response time with the minimum value in the response time returned by the other vehicles as the relay node.
In this step, the master node may not be directly connected to all nodes in the network, and for nodes that cannot be directly reached, a relay node needs to be selected; specifically, the newly decided master node sends an instruction (Search _ ID instruction) for inquiring a target vehicle to all nodes, all the nodes receiving the instruction Search surrounding networks to identify whether the target ID vehicle exists, and if so, a positive response is quickly given; and the node with the fastest response is taken as the relay node.

s1033, determining the delay time with the largest value among the delay times corresponding to each vehicle as the target network delay of the network formed by the master node and the relay node.
In the step, whether the newly built network can be accepted or not needs to be subjected to communication evaluation; specifically, the newly decided master node sends Echo instructions (Echo instructions) 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 main node, and selecting the maximum value (namely target network delay); if the target network delay is within the preset threshold range, finishing the network construction confirmation; if the preset threshold value is exceeded, repeating the previous network building process again until the set maximum attempt times are reached; here, the preset threshold may be a constant set in advance according to historical experience or experimental data. In the networking process, networking conditions of the network and a network confirmation link based on target network delay are increased, a relatively static network scheme is used for replacing a frequent dynamic networking process, precious energy consumption of vehicles is saved, vehicle performance is improved, and communication efficiency and communication quality of a motorcade are improved.
