Methods and systems are provided for adjusting powertrain torque in a vehicle based on driver intent. Driver intent is inferred based on foot motion inside a foot well monitored via a foot well region sensor and changes in clearance outside the vehicle monitored via a range sensor. By adjusting powertrain torque based on operator foot motion and traffic movements outside the vehicle, frequency of lash transitions can be reduced and lash transition initiation can be adjusted based on expected changes in torque demand.
