Abstract
A steering system and method for a vehicle having steerable front and rear wheels has rear hydraulic steering device that may be coupled to one or more of the rear wheels. A rear valve assembly may hydraulically control the rear hydraulic steering device to steer the rear wheels based upon a rear steering command from a controller. In a manual steering mode, the controller does not determine a rear steering command for the rear valve assembly such that the rear wheels are freely rotatable. In a rear steering assist mode, the controller determines the rear steering command based upon, at least in part, the manual steering input.
