step S1101: when the vehicle is started, the vehicle such as the unique identification frame number is sent to the network side, and the network side binds the received frame number with the IP address allocated to the vehicle-mounted product. When the network receives a request carrying the frame number information from an adjacent vehicle, the network can identify which vehicle information needs to be forwarded by the adjacent vehicle.
Step S1102: the vehicle-mounted vehicle checks the network state in real time, determines whether the vehicle-mounted vehicle cannot receive network information for a long time, determines whether the vehicle-mounted vehicle can normally access the network, and executes the detection according to the determination step S1103, if the vehicle-mounted vehicle tries to register the network again for timeout or the like, the vehicle-mounted vehicle still does not recover after the conventional detection is completed.
Judgment S11033: if the network checking result is normal, a normal network communication mode is adopted, otherwise, step S1103 is executed.
Step S1104: the host vehicle discovers nearby neighbors and, once established, may connect using C-V2X (Mobile Internet of vehicles) where C-V2X implements the 3GPP standard. After the connection is established, the vehicle sends a request help message to wait for the response of the adjacent vehicle, and after receiving the response of the adjacent vehicle, the vehicle immediately sends the information of the vehicle, such as the frame number, to the adjacent vehicle.
Step S1105: and the adjacent vehicle receives the help request and the frame number information from the vehicle, sends the help request and the frame number to the network terminal, and starts a detection process for distinguishing the information packet or the data packet which needs to be forwarded to the adjacent vehicle.
Step S1106: the network end receives the request packet sent by the adjacent vehicle and the vehicle frame number information of the vehicle, matches the IP address by using the vehicle frame number according to the IP address and the vehicle frame number binding information described in the step S1101, and generates a data information packet which is required to be sent to the vehicle and carries the vehicle frame number information to be sent to the adjacent vehicle. The network may perform according to the packet encapsulation format of fig. 12.
Step S1106: the adjacent vehicle receives the packet sent by the network to detect whether the information carries the mark bit and the vehicle frame number information, if the information carries, the side forwards the data packet to the vehicle for the information data packet which needs to be sent to the vehicle seeking help.
Step S1107: after receiving the information data packet forwarded by the adjacent vehicle, the vehicle analyzes the data information sent to the vehicle by the network.
The following illustrates the data encapsulation format of the data packet in this embodiment. Fig. 12 is a schematic diagram of a data packet encapsulation format according to an embodiment of the present invention, as shown in fig. 12, when an IP packet is encapsulated at a network side, a data packet that needs an adjacent vehicle to forward to the vehicle is encapsulated again, specifically, an option that uses an IP packet header is not used, a flag bit may be set to identify the data packet as a data packet that needs to be forwarded, and if the flag bit is set, 8 bits of 32 bits may be set to 10101010, and the combined flag is true. And the frame number of the vehicle is added from the front part of the data segment to package a new packet, the adjacent vehicle receives the new packet and needs to check whether the flag is true, if so, the new packet is considered to be forwarded to the vehicle, and if not, the new packet is considered to be the own data packet without being forwarded.
