A vehicle networking information delay transmission method based on MSPA algorithm belongs to the field of automobile mobile internet, and is to solve the problem that the present information transmission cannot aim at a network disconnection-connection condition. The process comprises the following steps of: producing an original relay node; broadcasting an information packet by using the relay node; and once playing the information packet at every step of 2R distance. When the relay node queries running in the same direction into itself transmitting coil inner vehicle node, a speed that the transmitting coil inner vehicle node bears off the transmitting coil is updated and calculated, thereby selecting the vehicle node of the minimum speed as the subsequent same-direction relay node. Firstly, the information packet is broadcasted once, and then an authority packet is sent to the subsequent same-direction relay node. When the relay node queries to the reverse direction vehicle node and a flag bit in the information packet is zero, the relay node changes the flag bit in the information packet to 1, and the information packet is broadcasted once, and then the authority packet according to the positive direction rule in the reverse direction is sent to the subsequent reverse direction relay node. The vehicle networking information delay transmission method is used for vehicle networking transmission information under the state of network disconnection-connection.
