摘要：
A method for operating a hybrid powertrain system includes monitoring operation of the torque machine, and limiting the motor torque output from the torque machine to a maximum allowable motor torque that is associated with an acceptable audible noise level when the motor speed of the torque machine is within a motor speed range associated with objectionable audible noise.
