Abstract
An electronic steering system for a vehicle includes a generally freely rotating steering column, a sensor for determining a rotational position of the steering column and a controller for turning tires on the vehicle based upon the rotational position of the steering column. When the vehicle is switched to one of various steer modes the controller electronically resets the rotational position of the steering column to a zero rotational position without physically turning the steering column. A steering brake limits over-rotation of the steering column to prevent the tires on the vehicle from turning beyond a safe distance. The controller electronically resets the rotational position of the steering brake when the steer mode is changed.
