The invention provides hybrid vehicle energy management torque control during transient and steady state operation transitions. A system and method for controlling a hybrid vehicle having an engine, a traction motor, and an automated stepped ratio transmission having a plurality of selectable discrete gear ratios, the systems and methods include operating an electric machine to provide an output torque associated with a first operating point selected based on a driver demand torque and a current driveline speed during transient operation; operating the electric machine to provide an output torque associated with a second operating point selected based on the driver demand torque and the current powertrain speed during steady state operation; and controlling an engine torque based on a difference between the driver demand torque and a motor torque.

    本公开提供了“瞬态与稳态操作转变期间混合动力车辆能量管理扭矩控制”。一种用于控制混合动力车辆的系统和方法,所述混合动力车辆具有发动机、牵引马达以及自动阶梯传动比变速器,所述自动阶梯传动比变速器具有多个可选离散齿轮比,所述系统和方法包括:操作电机以在瞬态操作期间提供与基于驾驶员需求扭矩和当前的动力传动系统转速选择的第一操作点相关联的输出扭矩;操作所述电机以在稳态操作期间提供与基于所述驾驶员需求扭矩和所述当前的动力传动系统转速选择的第二操作点相关联的输出扭矩;以及基于所述驾驶员需求扭矩与电机扭矩之间的差值来控制发动机扭矩。
