VEHICLE DYNAMIC CONTROL ALGORITHM AND ITS IMPLEMENTATION ON CONTROL PROTOTYPING SYSTEM

A design of controller for vehicle dynamic control (VDC) and its implementation on the real vehicle were introduced. The controller has been designed using a three-degrees-of-freedom (3DOF) yaw plane vehicle, and the control algorithm was implemented on the vehicle by control prototyping system dSPACE. A hybrid control algorithm, which makes full use of the advantages of robust and fuzzy control, was adopted in the control system. Field test results show that the performance of the vehicle handling dynamics with hybrid controller is improved obviously compared to that without VDC and with simple robust controller on skiddy roads (friction coefficients lower than 0.3).
