Abstract
Methods and apparatus for controlling the ramp in of current to an electronic power assisted steering motor associated with an auto stop-start engine are described. A controller is to determine a moving average voltage of a vehicle battery. The controller is also to determine a voltage rate of change based on the moving average voltage. The controller is also to determine a moving average engine speed of an auto stop-start engine of the vehicle. The controller is also to ramp in current to an electronic power assisted steering motor of the vehicle based on the moving average voltage, the voltage rate of change, and the moving average engine speed.
