Abstract

The invention discloses a synchronous connection method and a vehicle remote diagnosis system. According to the method, when a connection request sent to a device connector by a diagnosis device is monitored through the device connector, first report information that connection with the diagnosis device is established is sent to a vehicle connector so that it is ensured that the vehicle connectorestablishes connection with a to-be-diagnosed vehicle when receiving the first report information. The method for keeping the communication connection synchronization between the to-be-diagnosed vehicle and the diagnosis 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...
