Abstract:
A method for controlling output torque of a hybrid powertrain system includes determining a constrained output torque in response to an operator torque request, and determining maximum and minimum output torque limits. A time-rate change in the constrained output torque at each of a plurality of torque breakpoints is determined. A desired output torque is determined. A preferred output torque is determined as the desired output torque adjusted using the time-rate changes in the constrained output torque at the plurality of torque breakpoints and limited within the maximum and minimum output torque limits. Torque outputs of torque generators of the hybrid powertrain system are controlled in response to the preferred output torque.
