Control Strategy Modeling and Vehicle Performance Simulation Based on AMEsim-Simulink Interface

基于AMESim-Simulink/Stateflow联合仿真平台,对混联式液压混合动力车辆的传动系统与车辆控制器进行建模。根据车辆的预期行驶状况、蓄能器的压力情况与需求扭矩的变化,实时切换车辆不同的液压混合动力工作模式,采用CYC_1015车辆循环工况对其进行模拟分析。仿真结果表明,采用混联式液压混合动力驱动系统可明显提高车辆的燃油经济性,同时满足车辆的制动效果和动力性能。

Based on the AMEsim-Simulink/Stateflow joint simulation platform,the transmission system and the vehicle controller of a series-parallel hydraulic hybrid vehicle are modeled.According to the expected driving condition of the vehicle,the pressure condition of the accumulator and the change of the demand torque,the working mode of the vehicle in different hydraulic hybrid is switched in real time,and the CYC_1015 vehicle cycle condition is adopted for simulation analysis.Simulation results show that the most obvious effect of the series-parallel hydraulic hybrid driving system is to improve the fuel economy,and to meet the braking effect and dynamic performance of the vehicle.
