Abstract:
A method minimizes driveline disturbances in a vehicle having a motor generator unit (MGU) and a controller, which may be a motor control processor or a hybrid control processor. The method includes determining 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 a corrective final torque value for the MGU as a function of the set of motor values; and commanding the corrective final torque value from the MGU during a predetermined event, e.g., engine restart. Calculations and commanding the corrective final torque value are conducted by the controller within a calibrated minimum processing loop time. A vehicle includes first and second MGUs, and a controller electrically connected to the second MGU. The controller has the algorithm for minimizing driveline disturbances as noted above.
