| 摘 要： | 针对无级变速车辆在急加速工况下出现的动力疲软问题,提出了瞬态工况下基于有效功率的通用补偿控制方法.以变速器输入功率作为控制目标,克服了现有控制方法依赖于车辆及路况信息的缺陷,通过分层次量化补偿功率,将控制方法划分为功率维持、零功率、增加后备功率和综合模式等4种控制模式,为灵活设定过渡曲线和优化瞬态工况性能提供量化依据....

| Abstract: | To improve the drivability of continuously variable transmission(CVT) vehicle under hard acceleration condition,a compensation control strategy based on effective power was proposed.Different from the conventional control methods,which are dependent on vehicle and road environment information,this new strategy sets CVT input power as the control objective.A power compensation mode was ranked to four classes: holding power,zero power,increasing reserve power,and synthesis control.So,quantification criteria f... |
