增程式电动汽车控制策略研究
|
摘要
增程式电动汽车的控制策略直接影响整车的动力性、燃油经济性。通过确定发动机的最优工作曲线,制定了发动机最优工作曲线的控制策略,并运用Cruise与Matlab/Simulink仿真平台进行联合仿真,验证控制策略的可行性。与发动机定点工作策略进行比较,结果表明,最优工作曲线控制策略可以避免电池大电流放电,增加行驶里程,降低油耗。
The characteristic of power and fuel-economy are directly influenced by control strategy for an extended-range electric vehicle( E-REV). Optimized control strategies were designed based on engine optimal operational curves,and joint simulations between Matlab/Simulink and Cruise were carried out to validate the control strategies. Simulation results showed that high discharging current could be avoided as increasing of driving distance and decreasing of fuel consumption.
