Abstract
A steering system () for a vehicle including a steerable wheel () defining a steering angle (), a powered actuator () controlling the steering angle () and a steering wheel () providing a driver input control angle. A ratio of the driver input control angle to the steering angle () defines a steering ratio. The steering system () also includes a controller () selectively varying the steering ratio that directs the powered actuator () to change the steering angle () along one of at least two steering ratio graphs, and a control () manually selectable by a driver of the vehicle that communicates with the controllerfor selecting one of the steering ratio graphs. A first one of the graphs () varies as a function of the driver input control angle in a manner that is different than that of a second one of the graphs ().
