Abstract

The invention relates to the field of automotive fault diagnosis, and particularly relates to a fault recording device and method. The fault recording device comprises a gateway processor, a random access memory RAM which is connected with the gateway processor through a CAN bus, and an electric erasable programmable read only memory EEPROM. RAM stores a CAN bus message received by the gateway processor. After the gateway processor receives the CAN bus message with fault information, the CAN bus message which is stored in RAM and contains the fault information is written into EEPROM, and at the same time time information is acquired. The time information is used mark the CAN bus message written in EEPROM. According to the invention, if the whole vehicle has an electrical fault, and especially a sporadic fault, the real-time fault information can be easily and effectively recorded; and the efficiency of troubleshooting is improved.

Description

technical field [0001] The invention relates to the field of vehicle fault diagnosis, in particular to a fault recording device and method. Background technique [0002] Automobile fault diagnosis refers to the process of using special tools, instruments, equipment and software to detect, troubleshoot, analyze and judge automobile faults in accordance with relevant technical standards, so as to find out the cause of the fault and confirm the fault location. The diagnosis methods of automobile faults are basically artificial visual experience diagnosis method and instrument equipment diagnosis method. With the development of automobile technology, especially the application of electronic technology and computer technology in automobiles, automobile fault diagnosis is changing from traditional experience diagnosis methods such as eye observation, ear hearing, nose smell, hand touch, isolation, test and comparison to The development of a modern automotive fault diagnosis techn...
