The invention provides a point-to-point communication method between vehicles. The method comprises the following steps: a vehicle node application layer management module collects data in a wireless network, analyzes the source and the type of the data, realizes receiving and transmitting management of upper layer message information, and sets and monitors an encoding rule; a routing management module selects a routing mechanism, a routing request and a monitoring reply; an access management module obtains data on a routing layer, allocates a random target address to the routing layer at the same time, and then sends the address information into an MAC layer; a wireless transmission module is used for managing a transmitting antenna and a receiving antenna, carrying out corresponding processing on the data encoding result in a simulation mode, and transmitting the data in a corresponding transmission channel by the antenna. The invention provides the point-to-point communication method between vehicles, which is suitable for the frequent change condition of the topological structure of a vehicle network, improves the throughput of the network and reduces the network congestion.
