Zusammenfassung:Methods and systems are provided for operating a powertrain or driveline of a hybrid vehicle that includes two electric machines and a transmission are described. In one example, vehicle propulsion ismaintained while transmission operating parameters are determined for improving transmission operation. In particular, a rear drive unit maintains vehicle speed and monitors torque delivered via an output of the transmission. 描述了种提供用于操作包括两个电机和变速器的混合动力车辆的动力传动系统或传动系的方法和系统。在个示例中，在确定变速器操作参数以改进变速器操作的同时保持车辆推进。特别地，后部驱动单元保持车辆速度并且监测经由变速器的输出端传递的扭矩。
