The invention discloses an erasure coding and vehicle cooperation oriented vehicle-mounted network transmission control method, which comprises the steps of: firstly exchanging abstract collection and meeting probability collection between two communication vehicle-mounted nodes, then distributing data blocks by utilizing vehicle cooperation, and finally calculating transmission priority of a packet to realize dispatching of transmission tasks. The erasure coding and vehicle cooperation oriented vehicle-mounted network transmission control method reduces requirements of a network on the vehicle communication time as the transmitted packet is subjected to the block encoding by utilizing the erasure coding, improves transmission robustness as forward time of a relay node is increased, optimizes distribution of the data blocks between meeting vehicles as exchange and cooperation of abstract information of meeting vehicles is utilized, and avoids transmission of unnecessary data blocks as a BSPM strategy is selected for the transmission of the data blocks between vehicles; consequently the data transmission rate is increased, and the transmission time delay and transmission expense are reduced.
