A vehicle includes a powertrain and a controller. The powertrain includes a powerplant. The controller is programmed to, responsive to a tip-in resulting in a powertrain torque direction reversal and upon obtaining a base value of a desired powertrain lash angle, adjust a powerplant torque schedule. The controller is then subsequently programmed to adjust the desired powertrain lash angle from the base to an adjusted value based on an observed powertrain lash angle that corresponds to a maximum powertrain acceleration during the tip-in.
