TORQUE-GENERATING SYSTEM AND METHOD WITH IMPROVED POWER DOMAIN-BASED CONTROL AT ZERO SPEED

A torque-generating system includes one or more torque-generating devices, a transmission having an output member, and a controller. The controller executes a method to control an operation of the system when the output member is operating at zero output speed. The controller is programmed to determine a torque request level and an actual speed of the output member, and an effective speed of the output member, as a calibrated non-zero value, using the torque request level when the determined actual speed is zero. The controller calculates an effective power of the powertrain using the effective speed and torque request level. A control action is executed with respect to the powertrain using the calculated effective power, including transmitting powertrain control signals to the torque-generating device(s) to select an appropriate powertrain operating mode. 种扭矩生成系统包括个或多个扭矩生成装置、具有输出构件的变速器，以及控制器。当输出构件在零输出速度运行时，控制器执行控制系统运行的方法。控制器被编程为确定扭矩请求水平和输出构件的实际速度，以及当确定实际速度为零时，使用扭矩请求水平确定输出构件的有效速度为经校正的非零值。控制器使用有效速度和扭矩请求水平来计算传动
