Fault Alarms and Power Performance in Hybrid Electric Vehicles Based on Hydraulic Technology

In order to improve the fault alarm effect on power performance of hydraulic hybrid electric vehicles (HEV), this paper proposes a method for vehicle based technology, builds system model, uses technology extract characteristic signals key components, support vector mechanisms build classifier, and obtains results dynamic technology. The show that proposed can real-time diagnosis engine faults in HEV, be diagnosed after 5 s injection, thus ensuring stability HEV.
