Automation of Keypress Code Help

how can i make the 2 lines of code below automated so that they are automatically run without having the press xaxis or yaxis keys, if i remove the xaxis or yaxis from the lines i get an error, what do i replace the xaxis and yaxis with in the lines to make them excecute without a keypress, it is driving me mad trying to get this automated

turnPercent = Mathf.SmoothDamp(turnPercent, xAxis, ref turnVelocity, turnSpeed);

forcePercent = Mathf.Clamp(Mathf.SmoothDamp(forcePercent, yAxis, ref forceVelocity, forceChangeSpeed), -0.3f, 1f);

both lines execute perfectly when pressing the axis keys, but i am trying to add these to an ai vehicle and need to remove the need for keypresses

any help would be gratefully recieved, thank you in advance
