The embodiment of the invention discloses a communication method, system and terminal for vehicle formation driving. The communication quality between vehicle terminals can be ensured. The method provided by the embodiment of the invention is applied to a vehicle communication system, and comprises the following steps: a head vehicle terminal receives a signal sent by a second member terminal anddetermines first signal quality; a first member terminal receives the signal sent by the second member terminal and determines second signal quality; under the condition that the first signal qualityis lower than a reliability threshold value, the head vehicle terminal sends a first message, and the first message is used for searching a member terminal capable of serving as a relay node for a second member terminal; the first member terminal receives the first message and sends a second message according to the first message, and the second message comprises an identifier of the first memberterminal and second signal quality; and the head vehicle terminal receives the second message and determines that the first member terminal is a relay node for communication between the head vehicle terminal and the second member terminal according to the second message.
Description
