Abstract
Methods and apparatus for controlling an electronic power assisted steering (EPAS) motor in response to detecting engine stall while restarting an auto stop-start engine are described. A controller is to ramp out current from an EPAS motor in response to detecting that an auto stop-start engine is stalled. The controller is also to invoke a stall recovery attempt at the auto stop-start engine in response to the ramp out of current. The controller is also to ramp in current to the EPAS motor in response to detecting that the auto stop-start engine has been successfully restarted based on the stall recovery attempt.
