【Abstract】 The control strategy of electrical vehicle automatic starting based on nonlinear PI algorithm was proposed, the control algorithm was simulated by using Matlab/Simulink, and the simulation resultswere compared with traditional PI algorithm. The results show that the control strategy has such characteristics as faster response, no overshoot, higher accuracy, better adaptability, and can meet the practical driving demands.更多还原
