Abstract:
A powertrain system includes a transmission, torque generating device, load coupled to a drive axle, a final drive unit in meshed gear engagement with the output shaft and the drive axle, and a controller. A requested output torque is processed using an open-loop lash state model populated with a capped output torque request table and a lash closure rate estimate table respectively providing a capped torque value and an estimated lash closure rate. Output speed is determined using a plant model, the capped torque value, and the estimated lash closure rate. The powertrain is controlled during the transition using the output speed. A lash angle may be calculated from the closure rate using an integrator logic block. A calibrated lash offset profile may be determined using the lash angle, and a reference speed may be generated using the lash offset profile.

Claim (Index 2):
The powertrain system of  claim 1 , wherein execution of the instructions causes the controller to calculate a lash angle of the meshed engagement from the estimated lash closure rate using an integrator logic block, apply a calibrated lash offset profile that is determined using the lash angle, and control the dynamic operating state of the powertrain during the lash state transition by using the calibrated lash offset profile to determine the output speed.
