Car fault auto-detecting system and method

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...

AI Technical Summary

Problems solved by technology

Through this system, the driver can know that there is a fault in the car, but the specific fault must be determined by the maintenance personnel in the car repair shop.

In addition, there are also some systems in the car that do not have an ECU with fault self-checking, and the fault status can only be known when the specific maintenance is carried out.

And because the driver can't understand the existence of the fault in time, and make correct processing and elimination to the fault, it often leads to the occurrence of traffic accidents, which seriously affects the safety of life and property.
