Abstract
A vehicle includes an engine configured to auto stop and auto start. The vehicle includes an active front steering system with an electric actuator. A controller operates the electric actuator at a current limit that is less than a requested current of the electric actuator in response to a request to change a steering ratio by an amount that results in the requested current being greater than the current limit during an engine auto stop event. The current limit may decrease from the requested current to a predetermined limit after transitioning to the engine auto stop event. The current limit may increase from the predetermined limit to the requested current after transitioning from the engine auto stop event.
