摘要
增程式电动汽车可以有效地解决纯电动汽车续驶里程不足的问题。以增程式电动汽车为研究对象,设计基于模糊控制的能量分配策略,利用Cruise与MATLAB/Simulink进行联合仿真,通过NEDC工况试验验证该策略的有效性。研究表明:基于模糊控制的能量分配策略具有较强的鲁棒性,控制效果较好,可有效降低排放,维持电池SOC在理想范围内,避免过冲、过放。
Extended range electric vehicle can effectively solve the problem that the driving mileage of pure electric vehicle is not sufficient. Taking the extended range electric vehicle as a research subject,a kind of energy distribution strategy was designed based on the fuzzy control theory. The strategy was simulated by Cruise and MATLAB /Simulink and its effectiveness was validated by the NEDC condition test. The results show that the strategy based on fuzzy control theory has strong robustness and is well controlled; meanwhile,it can also reduce emissions effectively and keep battery SOC in an ideal range,which avoids overshoot or over-discharge.
