Embodiment Construction

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] With the widespread use of automotive electronic control units (ECUs) in automobiles, the method of using OBD systems to diagnose ECU faults is currently the mainstream choice for automotive fault diagnosis. The current car diagnosis is mainly based on the CAN line or K line (K line is a line for data transmission between the car’s ECU and the diagnostic instrument). Among them, the K line-based diagnosis is realized by half-duplex...

Abstract

The embodiment of the present invention discloses a network connector and a vehicle diagnosis method, wherein the network connector is used to connect the ECU and the diagnostic instrument, the network connector and the ECU are connected in a wired manner, and the network connector and the diagnostic instrument are connected in a wireless manner; the network The IP address of the connector is in the same network segment as the IP address of the ECU and the IP address of the diagnostic instrument; when the network connector receives the data reading request sent by the diagnostic instrument, it forwards the data reading request to the ECU by wire , the data reading request is used to request the ECU to read the diagnostic data of the vehicle; when the network connector receives the diagnostic data fed back by the ECU in response to the data reading request, the diagnostic data is sent to the diagnostic instrument wirelessly. By adopting the invention, the ECU and the diagnostic instrument can be connected in a wireless manner, so that the DoIP diagnosis process of the automobile is more convenient.

Description

Technical field [0001] The present 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 maintenance of cars is an important measure to ensure safe driving of drivers. The prerequisite for car maintenance is to grasp the operating conditions of various parts of the car, and to find out the location and cause of the failure. On-Board Diagnostics (OBD) can be used to monitor the running 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 use of diagnostic services introd...
