摘要
针对双离合器插电式混动起步过程中多动力源和双离合器协调控制问题展开研究。首先,对系统不同起步模式进行动力学分析,建立了系统数学模型和起步性能评价指标。在此基础上,考虑了SOC、载荷、坡度等因素和驾驶员起步意图提出了系统起步模式决策方法,以最大冲击度为约束制定各起步模式动力源和双离合器协调控制策略。仿真结果表明:不同工况下起步模式选择合理,最大冲击度为7.31 m/s3,最大滑摩功为4.94 kJ,均控制在合理范围内,验证了本文策略的有效性。
The coordinated control of multiple power sources and dual clutches in the starting process of dual clutch plug-in hybrid vehicle is studied.Firstly,the dynamics of different starting modes of the system is analyzed,and the system mathematical model and starting performance evaluation index are established.On this basis,considering SOC,load condition,slope and other factors and the driver's starting intention,the system starting mode decision-making method is established.The coordinated control strategy of power source and dual clutch for each starting mode is formulated with the maximum impact as the constraint.The simulation results show that the selection of starting mode under different working conditions is reasonable.The maximum impact degree is 7.31 m/s3,and the maximum sliding friction work is 4.94 kJ,all within a reasonable range,which verifies the effectiveness of the strategy.
