Fault diagnosis is one of the focuses in automobile research. EPS and SAS have represented the development trend of steering and suspension mechanisms. A fault diagnosis system has been developed hased on the software platform of VB and SQL Server, a system making use of intelligent diagnosis function of the experts system to do interrogation operation based on the fault symptoms observed by man and collected signals, analyzing faults quickly, finding out the cause of the problem and solutions as well as displaying them. Comparing a fault diagnosis example with the actual faults, the result shows that the developed fault diagnosis system is able to diagnose the faults on EPS and SAS correctly, thus exploring an eft~etive and feasible method fur the fault diagnosis of vehicle chassis system.
