通过对P2混合动力驱动系统核心部件的动力学分析,建立了系统动力学数学模型,并基于MATLAB/Simulink搭建了混合动力驱动系统的仿真模型,并进行了仿真.仿真结果表明:车辆匹配P2混合动力驱动系统时,车辆0~80 km/h加速性可从发动机独立驱动的16.5 s提升到联合驱动的13.5 s,表明P2混合动力系统的方案可行性和性能优越性.

Through the dynamic analysis of the core components of P2 hybrid drive system,the mathematical model was established,and the simulation model of the hybrid drive system was built based on MATLAB/Simulink.The simulation results show that:when the vehicle is equipped with P2 hybrid drive system,the 0~80 km/h acceleration of the vehicle can be improved from 16.5 s of independent engine drive to 13.5 s of combined drive,which verifies the feasibility and performance superiority of P2 hybrid drive system.
