针对混合动力汽车制动能量回收少的问题,论文采用逻辑控制设计了一种制动能量再利用策略,在保证车辆制动稳定性的同时合理分配前后轮的制动力,从而使回收能量最大化。根据该策略在Matlab/Simulink环境中搭建仿真模型,并将此模型嵌入车辆仿真软件ADVISOR进行仿真。仿真结果表明,该控制策略相对于ADVISOR本身的再利用策略,电池荷电状态曲线明显改善,有效解决了制动能量回收少问题。
Aiming at the problem of low braking energy recovery in hybrid electric vehicle ,this paper designed a kind of braking energy reuse strategy by us ng logic control.On condition that the stability of the vehicle braking at the same time a reasonable allocation of front and rear wheel braking force,make the recovery of energy to maximize.According to this strategy,the simulation model was built in the Matlab/Simulink environment, and thesimulation model was embedded in the ADVISOR a software for vehicle simulation to simulate.The simulation results show that compared with the reuse strategy of ADVISOR itself, the battery charge state curve is improved obviously,which effectively solves the problem c fless braking energy recovery.
