Outline of Final Research Achievements

The spread of electric vehicle (EV) is indispensable for the realization of the smart city with a little environmental load, and the development of EV becomes the key by energy saving in the next generation when we overcome problem of current EV. Therefore, by this research, I developed the practical EV control methods in the next generation to realize high kinetics, safety and electric power saving. It is a precision well control method by integrating the regenerative brake equipment, a slip rate control, vehicle posture control and so on by utilizing characteristics of EV enough. The method has robustness property against the various changing road conditions. Specifically, 2DOF (degree of freedom) PID control method by designing the MPC algorithm and the method combination expansion and improved sliding mode control wand MPC. And then, these methods are verified the effectiveness of safety, electric power saving characteristics and motion performance by experiments.
