The invention relates to engine torque smoothing. A method of controlling torque applied to a powertrain of a hybrid vehicle based on the present application includes: operating an engine, the engine being part of the powertrain; estimating an engine generated torque or angular acceleration profile during operation of the engine; identifying, based on the estimated torque or angular acceleration profile, a period in which an instantaneous torque or an instantaneous acceleration expected to be generated by the engine exceeds a specified threshold, the specified threshold being an instantaneous torque threshold or an instantaneous acceleration threshold; and applying reaction torque from the energy source or sink to components of the powertrain during the identified period such that the expected total powertrain torque does not exceed the specified threshold, where the specified threshold varies as a function of engine speed and transmission gear.

    本申请涉及发动机扭矩平滑。基于本申请的控制施加到混合动力车辆的动力传动系的扭矩的方法,其包括:运行发动机,所述发动机是动力传动系的一部分;在所述发动机的运行期间估计发动机产生的扭矩或角加速度曲线;基于所估计的扭矩或角加速度曲线,识别其中预期由所述发动机产生的瞬时扭矩或瞬时加速度超过指定的阈值的时段,所述指定的阈值是瞬时扭矩阈值或瞬时加速度阈值;并且在所识别的时段期间将来自能量源或汇的反作用扭矩施加至动力传动系的部件,使得预期的总动力传动系扭矩不超过所述指定的阈值,其中,所述指定的阈值根据发动机转速和变速器挡位而变化。
