Patent ID: 8583306

Claim:
A control module-implemented method for controlling output torque of a hybrid powertrain system, comprising: determining a constrained output torque in response to an operator torque request; determining maximum and minimum output torque limits; determining a time-rate change in the constrained output torque at each of a plurality of torque breakpoints, comprising dividing the constrained output torque into a plurality of torque breakpoints between a minimum achievable output torque and a maximum achievable output torque and calculating a time-rate change in the constrained output torque at each of the plurality of torque breakpoints; determining a desired output torque; determining a preferred output torque comprising the desired output torque adjusted using the time-rate changes in the constrained output torque at the plurality of torque breakpoints limited within the maximum and minimum output torque limits; and employing the control module to control torque outputs of torque generators of the hybrid powertrain system in response to the preferred output torque.
