Problems solved by technology
The invention discloses an electric vehicle NVH optimization-based driving control method. A new controller is designed for an input and an output of an electric vehicle driving control system, a fuzzy control idea is introduced to a speed loop controller, the robustness and more rapid speed response of a speed ring are improved, a forecast control idea is introduced to a current loop controller,a new speed forecast controller is designed, and the dynamic performance and the steady performance of the electric vehicle driving control system are improved. On the basis, dead zone error voltage compensation is performed on an output voltage of a forecast controller, an input voltage of an inverter is compensated at a current loop, the unfavorable influence of a dead zone effect on an output voltage is improved, so that the driving control system obtains more rapid current dynamic response, better steady control accuracy and higher interference resistance, torque fluctuation is prevented by voltage dead zone compensation, and an electric vehicle obtains better NVH performance and has better application value.
