The invention provides a control element and a method for operating an electric power train. A vehicle includes and engine and a transmission having a torque converter with an impeller and a turbine. An electric machine is fixed to the impeller. At least one controller is programmed to, in response to a difference between measured and estimated speeds of the impeller exceeding a threshold, command a torque to the electric machine based on a maximum of the measured and estimated speeds of the impeller, and programmed to, in response to the difference being less than the threshold, command another torque to the electric machine based on the measured speed of the impeller.

    本公开提供了“用于操作电动动力传动系统的控制件和方法”。一种车辆,包括发动机和变速器,所述变速器具有带泵轮和涡轮的变矩器。电机固定到所述泵轮。至少一个控制器被编程为,响应于所述泵轮的测量转速和估计转速之间的差值超过阈值,基于所述泵轮的所述测量转速和估计转速中的最大值来向所述电机命令扭矩,并且被编程为,响应于所述差值小于所述阈值,基于所述泵轮的所述测量转速来向所述电机命令另一扭矩。
