Patent ID: 8494700

Claim:
A method for minimizing driveline disturbances in a vehicle having a motor generator unit (MGU) and a controller, the method comprising: determining, via the controller, a set of motor values of the MGU, including a change in motor speed, a derivative of the change in motor speed, and a motor jerk value; calculating, via the controller, a corrective final torque value for the MGU as a function of the set of motor values, including: multiplying the change in motor speed by a first calibrated coefficient to thereby determine a delta speed torque value; multiplying the derivative by a respective one of a second and a third calibrated coefficient when the derivative is positive or negative to thereby determine a speed derivative torque value; multiplying the motor jerk value by a respective one of a fourth and a fifth calibrated coefficient when the motor jerk value is positive or negative to thereby determine a delta derivative torque value; and calculating the corrective torque value as a function of the delta speed torque value, the speed derivative torque value, and the delta derivative torque value; and commanding the corrective final torque value from the MGU during a predetermined event of the vehicle to thereby minimize the driveline disturbances during the predetermined event; wherein determining the set of motor values, calculating the corrective final torque value, and commanding the corrective final torque value are each conducted by the controller and fully within a calibrated minimum processing loop time of the controller.
