The Driving Control Strategy of Pure Electric Vehicle Based on Fuzzy Self-adaptive PID

摘要

For the problem of pure electric vehicle drive control, a speed-current double closed loop control strategy was proposed by using the fuzzy self-adaptive PID theory, and the vehicle simulation model was established in Matlab/Simscape. The performance of the drive control strategy was verified by starting operation condition and NEDC cycle in the simulation model. Simulation results show that the pure electric vehicle drive control strategy based on the fuzzy adaptive PID can execute the driving instructions quickly and accurately, and the vehicle can operate stably without static speed error, so the control strategy can improve the vehicle driving performance effectively.
