Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] With the widespread use of electronic control units (Electronic Control Unit, ECU) in automobiles, the method of using OBD system to diagnose ECU faults is the mainstream choice for fault diagnosis of automobiles. The current car diagnosis is mainly based on the CAN line or the K line (the K line is a line for data transmission between the ECU of the car and the diagnostic instrument), and the diagnosis based on the K line is realized by half-duplex serial co...

Abstract

The embodiment of the invention discloses a network connector and a vehicle diagnostic method. The network connector is used for being connected with an ECU and a diagnostic instrument, the network connector is connected with the ECU in a wired mode, and the network connector is connected with the diagnostic instrument in a wireless mode. The IP address of the network connector is located in the same network segment with the IP address of the ECU, and the IP address of the diagnostic instrument. The network connector, when receiving a data reading request sent by the diagnostic instrument, forwards the data reading request to the ECU through a wired mode, and the data reading request is used for requesting the ECU to read the diagnosis data of a vehicle. The network connector, when receiving the diagnosis data fed back by the ECU for the data reading request, sends the diagnosis data to the diagnostic instrument in a wireless manner. By means of the present invention, the ECU and the diagnostic instrument can be connected in a wireless manner, so that the automobile DoIP diagnosis process is more convenient.

Description

technical field [0001] The invention relates to the technical field of automobile communication, in particular to a network connector and a vehicle diagnosis method. Background technique [0002] With the development of automotive electronics technology and the improvement of living standards, cars have become an essential tool for people to travel. Regular car maintenance is an important measure to ensure the safe driving of drivers. The premise of automobile maintenance is to master the operation status of various parts of the automobile, and find out the location and cause of the failure. The on-board diagnostic system (On-BoardDiagnostic, OBD) can be used to monitor the operating status of the engine and the working status of the exhaust gas treatment system at any time, and can help maintenance personnel to determine the nature and location of the fault by reading the fault code of the car. [0003] Diagnostic communication over Internet Protocol (DoIP) refers to the ...
