摘要
介绍了以内燃机工作特性为基础的某混合动力系统的控制算法。利用CRIUSE建立了该混合动力系统和整车动力学模型,控制策略模型则在Matlab/Simulink环境下实现。通过仿真计算,在满足动力性的前提下,该系统和控制算法对车辆的燃油经济性提高显著,在电能自平衡工况下,城市循环工况油耗为7.3 L/100 km,节油循达33%;外部充电时,综合节油率可达50%。
The control algorithm of a hybrid powertrain system based on the characteristic of IC engine was introduced. The models of the powertrain components as well as the vehicle were built based on the software CRIUSE, and the controller was coded in the Matlab/Simulink environment. The numerical experiments validate that the hybrid system and control greatly improve the fuel economy while the performances are satisfied. In the case of electrical self-equalizing, the fuel consumption of city circalation is 7.3 L/100 km. and the reduction of diesel fuel consumption reaches 33 %. When charged by the outside power source, the reduction of diesd fuel consumption can reach 50 %.
