Abstract:
A system and method for controlling backlash in a vehicle powertrain includes the step of controlling a torque request of the powertrain with a first control strategy after an occurrence of a backlash predictor and before an occurrence of a backlash. Another step may be employed whereby the torque request is controlled with a second control strategy after the first control strategy and before the occurrence of the backlash such that a torque request level is below a highest torque request level obtained during the first control-strategy.
