Embodiment Construction

[0027] Including a fault identification module, a fault processing module, a fault reminder module, a fault code storage module and a fault code clearing module;

[0028] The fault identification module detects the signal status of each component in the system, and judges in real time whether each signal is abnormal;

[0029] The fault processing module automatically handles faults that affect the normal operation of the electronic control system, and replaces the signal with a fixed value to ensure that the entire system can continue to run, and it is also convenient for calibration engineers to easily find the fault signal;

[0030] The failure reminder module reminds the driver that the electronic control system is abnormal through the buzzer or the instrument panel;

[0031] The fault code storage module stores fault codes in the electrically erasable memory EEPROM; a unique fault code is set for each detected fault, and when the ignition switch is turned off, all fault co...

Abstract

The invention relates to a fault self-diagnosis system and method for an electronic control system and belongs to a vehicle fault self-diagnosis system and method. The fault self-diagnosis system comprises a fault identification module, a fault processing module, a fault reminding module, a fault code storage module and a fault code eliminating module. The fault self-diagnosis method comprises the following steps: detecting fault information of each component in an automatic clutch system in real time, judging a specific location where a fault occurs, reminding a driver that the system is in fault and storing the fault information for providing guidance for a maintenance man, so that the maintenance man can conveniently and rapidly find the specific location where the fault occurs and replace a damaged part. The fault self-diagnosis system and method provided by the invention have the advantages that the system and method are different from the traditional manual fault isolation, an electronic means is utilized for detecting and diagnosing functions and faults of system components, accurate fault information can be produced, the faults are rapidly and accurately located, fault check time is shortened, and fault isolation efficiency is greatly improved.

Description

technical field [0001] The invention relates to an automobile fault self-diagnosis system and method, and is especially suitable for an automobile automatic clutch electric control system. Background technique [0002] With the rapid growth of the world's car ownership, electronic control technology has been widely used in cars. On the one hand, it has greatly improved the economy and power of modern cars. and difficulty of maintenance. At present, it is difficult to adapt to relying only on traditional manual experience detection and diagnosis, and it can no longer meet the needs of customers in terms of diagnostic accuracy, convenience of use and work efficiency. [0003] The clutch system is an important assembly of the automobile transmission system, so its fault diagnosis is of great significance to the safety and reliability of the automobile. Automotive automatic clutch, also known as automatic clutch control system, is an intelligent clutch control system developed...
