Embodiment 1

[0038] Such as figure 1 Shown, a kind of fault diagnosis method of automobile internal parts or circuit, comprises the following steps:

[0039] S1: Collect vehicle fault data; generally speaking, the vehicle fault data collected here are fault codes, and each fault code corresponds to a different possible cause of the fault; The vehicle ECU is connected for data collection, and the vehicle diagnostic equipment VCI is used to monitor whether the working status of each system in the vehicle is abnormal. form is stored. The system can perform self-diagnosis according to DTC to repair or maintain the vehicle in time. OBD can also be equipped with OBD interface, which can communicate with external vehicle diagnostic equipment, so that maintenance personnel can use the above-mentioned equipment to read timely. To DTC, and repair and maintain the vehicle, reducing the time of manual diagnosis; vehicle ECU (Electronic Control Unit), which is arranged in various systems of the vehic...

Embodiment 2

[0053] A system using the fault diagnosis method for automotive internal components or circuits as described in any one of the above, comprising:

[0054] Acquisition module: used to collect vehicle fault data; the acquisition module here can be a vehicle diagnostic device VCI, which is connected to the vehicle ECU for data collection;

[0055] Fault simulation circuit diagram module: used to receive data from the acquisition module, feed back faulty components or lines, and give maintenance plans at the same time. At the same time, the maintenance plan in the fault simulation circuit diagram module includes maintenance fault points, fault phenomena, and troubleshooting plans. Maintenance personnel can use it directly when encountering the same failure, improving maintenance efficiency;

[0056] Interaction module: used to interact with the outside world, the vehicle fault data of the acquisition module is transmitted to the fault simulation circuit diagram module through the ...

Embodiment 3

[0059] A medium, the storage medium has a plurality of instructions, and the instructions are suitable for being loaded by a processor to execute the steps in any one of the methods for diagnosing faults of automotive internal components or circuits described above. The storage medium in this embodiment may be a readable signal medium or a readable storage medium. The readable storage medium may be, for example, but not limited to, an electrical, magnetic, optical, electromagnetic, infrared, or semiconductor system, device, or device, or any combination thereof. A computer readable signal medium may include a data signal carrying readable program code in baseband or as part of a carrier wave. Such propagated data signals may take many forms, including but not limited to electromagnetic signals, optical signals, or any suitable combination of the foregoing. A readable signal medium may also be any readable medium other than a readable storage medium that can transmit, propagat...

Abstract

The invention discloses a fault diagnosis method and system for automobile internal parts or lines and a medium, and belongs to the field of automobile diagnosis. In order to solve the problems that an existing automobile is low in maintenance efficiency and high in cost, the invention provides a fault diagnosis method for automobile internal parts or lines, which comprises the following steps: collecting automobile fault data; sending the fault data to a fault simulation circuit diagram; S3, the fault simulation circuit diagram feeding back a fault part or line according to the received automobile fault data, and feeding back a corresponding maintenance scheme at the same time; and S4, maintenance personnel carring out corresponding automobile fault diagnosis and troubleshooting according to the maintenance scheme. According to the invention, specific fault parts or fault lines are fed back through the fault simulation circuit diagram according to the received fault data, and then a corresponding maintenance scheme is given, so that the time and efficiency of automobile fault maintenance are greatly improved; and a specific fault point can be quickly found according to the fault data, so that the time cost is saved. The whole system is clear in division of labor and simple in composition.

Description

technical field [0001] The invention belongs to the technical field of automobile diagnosis, and more specifically relates to a method, system and medium for fault diagnosis of automobile internal components or circuits. Background technique [0002] With the increasing requirements of relevant national laws and regulations and the continuous improvement of the electrification degree of automobiles, the internal structure of automobiles in my country is becoming more and more complex, and the application technology of automobiles is also developing continuously. At the same time, the automobile maintenance industry is also facing more Technical challenges, but also more opportunities. On the one hand, new technologies such as complex engine fuel systems, after-treatment systems, automatic transmissions, and driver assistance are gradually added to new vehicles, which imposes higher requirements on the theoretical knowledge and techniques of vehicle maintenance personnel. Too...
