Abstract

The application discloses a synchronous connection method and a vehicle remote diagnosis system. In the method, when the device connector listens to the connection request sent by the diagnostic device to the device connector, it sends the first report information that the connection with the diagnostic device has been established to the vehicle connector, so as to ensure that the vehicle connector is receiving When the first report message arrives, establish a connection with the vehicle to be diagnosed. A method for maintaining synchronous communication connection between the vehicle to be diagnosed and the diagnostic equipment is realized.

Description

technical field [0001] The application belongs to the technical field of automobile diagnosis, and in particular relates to a synchronous connection method and a vehicle remote diagnosis system. Background technique [0002] Vehicle remote diagnosis based on network protocol DoIP (Diagnostic communication over Internet Protocol) protocol is one of the common vehicle remote diagnosis methods. When remote vehicle diagnosis is performed based on the DoIP protocol, the corresponding transport layer usually uses UDP or TCP protocol for data transmission. Since the TCP protocol is a connection-oriented protocol, when data transmission is performed based on the TCP protocol, it is necessary for the vehicle to be diagnosed and the diagnostic device to maintain the synchronization of the communication connection. At present, when remote vehicle diagnosis is performed based on the DoIP protocol, no method is proposed to solve the problem of how to keep the communication connection sy...
