Vehicle troubleshooting method, device and equipment and computer readable storage medium

Abstract

The invention relates to vehicle troubleshooting method, device and equipment and a computer readable storage medium, and the method comprises the steps: carrying out the communication with a controlsystem of a vehicle through a UDS diagnosis protocol, and setting a configuration frame in the control system; and performing data writing operation on the configuration frame, writing a target memoryaddress in the configuration frame, the target memory address being used for controlling the system to obtain data in a corresponding memory, writing the obtained data in a sending frame carrying a preset identifier, and uploading the sending frame after the data is written to a vehicle network; and obtaining a sending frame with a preset identifier from a vehicle network, and reading data from the obtained sending frame for troubleshooting. Detection personnel can obtain related data in a memory corresponding to the control system only by configuring a memory address, various unpredictable faults can be conveniently and rapidly checked, the fault problem can be rapidly positioned, and compared with a traditional vehicle fault detection mode, the reliability of vehicle fault checking is improved.

Description

technical field [0001] The present application relates to the technical field of vehicle safety detection, and in particular to a vehicle troubleshooting method, device, equipment and computer-readable storage medium. Background technique [0002] With the improvement of people's living standards, cars have gradually entered thousands of households and become the most important means of transportation, and the safety of car driving is one of the important indicators of cars. Taking automobiles as an example, the electronic control unit (Electronic Control Unit, ECU) of modern automobiles is becoming more and more integrated, and the software running in it is also becoming more and more complex. The vehicle environment and working conditions are ever-changing, and various failures will inevitably occur. In order to quickly locate faults, ECUs generally integrate Unified Diagnostic Services (UDS), which can be integrated into the predictable fault development stage, and can b...

Problems solved by technology

[0003] For unpredictable faults, the traditional vehicle fault detection method is to use UDS's Read Memory By Address Service (Read Memory By Address Service) for troubleshooting and analysis, but this service is question-and-answer, that is, the diagnostic tool sends a piece of data to tell the ECU to read The address and length of the memory, and then the ECU replies to the data of the corresponding memory, the real-time performance is very poor, and it is impossible to capture the situation of rapid changes

The traditional vehicle fault detection method has the disadvantage of low fault detection reliability
