Abstract

The invention discloses a method and system for predicting a fault. The system comprises a vehicle-mounted terminal and a vehicle networking platform. The vehicle-mounted terminal arranged at a vehicle is used for determining a rail pressure drop slope of a fuel injector in the vehicle according to a rail pressure parameter and running time of the vehicle. The vehicle networking platform connectedto the vehicle-mounted terminal is used for predicting whether the fuel injector has a potential fault hazard based on the rail pressure drop slope. According to the invention, a technical problem that fault occurrence can not be predicted and fault diagnosis is carried out by taking related measures only after fault occurrence at the vehicle according to the existing vehicle fault detection planin the prior art is solved.

Description

technical field [0001] The invention relates to the field of fault detection, in particular to a method and system for predicting faults. Background technique [0002] With the improvement of people's living standards, automobiles have become a must-have travel tool for every household. However, with the popularity of various vehicles such as automobiles, vehicle failures are often encountered during driving and use of vehicles, such as engine startup. Difficulties, oil leaks in cars, water leaks in cars, failure of lighting systems, etc. During the driving and use of the vehicle, the failure of the vehicle will cause the user's personal and property safety to be threatened to varying degrees. [0003] However, the fault detection schemes in the prior art all perform fault diagnosis after the vehicle fails, and then confirm the fault and repair the fault. It is impossible to predict the fault of the vehicle. In this case, the personal and property safety of the user has bee...
