Study on coordination control of ESC and DFAS systems for distributed driving electric vehicles

Presenting a coordinated control algorithm that takes into account both electric stability control (ESC) and drive force assisted steering (DFAS) performance. It introduces the correction factor ki of the driving force when driving the power steering, which designed by fuzzy control the factor with the different vehicle attitude and conditions of the rules of change, and finally the basic control of the coordination process framework is given. In order to verify the feasibility of coordinated control strategy, through the Carsim/Simulink simulation platform to establish coordination control model, simulation results show that the coordinated control algorithm of both the good stability and the driving power steering performance. The experimental results verify the feasibility of the proposed coordinated control algorithm.
