A steering system ( 10 ) for a vehicle includes at least one wheel ( 14 ) that pivots to define a steering angle ( 20 ), and a steering lock ( 12 ) that limits an input to the steering angle ( 20 ) from an operator to a selected maximum value. The steering system ( 10 ) also includes a motor operatively connected to the wheel ( 14 ) that augments the input to the steering angle ( 20 ) from the operator, and a controller ( 42 ) operatively connected to the motor and adjusting the augmentation of the input to the steering to provide a maximum angle from the operator based upon at least one operating parameter, that includes the size of the wheel, thereby allowing the wheel ( 14 ) to pivot to a steering angle ( 20 ) based on the operating parameter that exceeds the steering angle ( 20 ) corresponding to the maximum allowable value as defined by the operator input. |
