Abstract

The invention provides an automobile failure automatic-detecting system, for obtaining state signals of vehicle signal collecting units of all detected systems in an automobile, and making remote analysis of automobile failure to in time inform the driver of the automobile, and comprising: vehicle central control unit, vehicle display unit, vehicle wireless data communication unit, and wireless data communication unit and failure analyzing unit arranged in a remote service center. Besides, the invention provides an automobile failure automatic-detecting method, comprising the steps of: detecting automobile state information, transmitting automobile state information, analyzing automobile failure, transmitting automobile failure information, and displaying automobile failure information. Relative to the existing techniques, the invention can in time, visually and completely reflect the automobile failure information, improving the automobile safety performance and having a simple and reasonable structure as well as being easy to implement.

Description

technical field [0001] The invention relates to an automobile safety detection system, in particular to an automobile fault automatic detection system. [0002] The invention also relates to a method for automobile safety detection, in particular to a method for automatic detection of automobile faults. technical background [0003] In recent years, the rapid development of automotive electronics technology has greatly improved the performance of the car. Automobiles have developed from purely mechanical products to advanced mechatronics products. Some key systems inside the car have been electronically controlled, and an electric control unit (Electric Control Unit, ECU) is used as its control center. In fact, fault information is already analyzed, processed and stored in these ECUs. For example, the control computer ECU of electronically controlled fuel injection automobile engine is equipped with a fault self-diagnosis system. When the car is running normally, the vol...
