Abstract
A method to monitor integrity of a motor torque command for a transmission in a hybrid powertrain system includes calculating motor torque commands for the torque generating machines. Torque corrections for the motor torque commands are determined. The motor torque commands are adjusted based upon the torque corrections. The adjusted motor torque commands are verified based upon an estimated output torque.
