    Abstract: A vehicle includes a torque device providing input torque, a transmission, an axle connected to drive wheels, a final drive unit, and a controller. The controller includes proportional-integral (PI) logic, and is programmed to determine a speed of the drive wheels and output shaft. The controller executes a method to calculate a reference output speed using the drive wheel speed and applies a calibrated offset profile to the calculated reference output speed during a lash state transition of the final drive unit, output shaft, and axle. This controls, via the PI logic, a speed difference between the output shaft and drive axle. The calibrated offset profile is higher in an early portion of the lash state to speed a transition from the lash state, and lower in a later portion of the lash state to reduce driveline clunk upon transition from the gear lash state.

    Abstract: A method for managing output bump/clunk in a neutral state in a strong hybrid vehicle includes calculating a motor torque for an electric traction motor connected to a third node of a planetary gear set. The motor torque is calculated as a product of a predetermined inertia of the electric traction motor, the calculated acceleration of the engine, and a gear ratio of the planetary gear set. The calculated motor torque is commanded from the electric traction motor via a controller in a direction opposite the calculated acceleration of the output shaft, including transmitting a motor torque command to the electric traction motor for the duration of the neutral state. The vehicle includes the engine, a damper assembly, the transmission, and the controller.

    Abstract: A powertrain includes a controller and gear sets, clutches, rotatable members, and torque actuators, e.g., an engine and one or more motor/generator units. Each torque actuator outputs a total control torque. The total control torque from a given actuator is used to achieve a target value, which is a torque value of a member of one of the gear sets, clutches, or rotatable members. The controller includes proportional-integral (PI) control logic. The total control torque is the sum of proportional and integral torque terms from the PI control logic. The controller detects a predetermined vehicle event, for instance a change in a hybrid range state or a control gain reduction event, and then automatically resets the integral control torque term(s) for the physical target value during the requested vehicle event to thereby maintain the total control torque for the same target value through the execution of the predetermined vehicle event.
