混合动力传动系统转速控制
摘要：
本发明公开提供一种混合动力传动系统转速控制。在至少一个实施例中，一种车辆动力传动系统包括通过离合器机械地连接的发动机和电机。所述动力传动系统还包括变矩器，所述变矩器被构造为将电机流体地连接到输出轴。控制器被配置为：基于传递穿过离合器的预测的扭矩，命令至变矩器的电机的转速输出。所述控制器进一步被配置为：基于电机的命令的转速输出和实际的转速输出之间的差异来修正所述命令。
摘要（英）：

In at least one embodiment, a vehicle powertrain includes an engine and an electric machine mechanically coupled by a clutch. The power train also includes a torque converter configured to fluidly couple the electric machine to an output shaft. A controller is programmed to command a rotational speed output of the electric machine to the torque converter based on a predicted torque delivered across the clutch. The controller is further programmed to modify the command based on a difference between the commanded rotational speed output and an actual rotational speed output of the electric machine.
