Abstract:
A steering system is provided for an agricultural vehicle having steerable wheels of a first wheel set, first and second steerable wheels of a second wheel set, and a steering input device configured to receive a manual steering input for the wheels of the first wheel set. The steering system includes first and second hydraulic steering devices coupled to the first and second steerable wheels of the second wheel set; a valve assembly configured to hydraulically control the hydraulic steering devices to steer the wheels of the second wheel set; and a controller configured to determine steering commands and provide the steering commands to the valve assembly. In a rear stability mode, the valve assembly is configured to selectively dampen fluid flow between the first and second hydraulic steering devices.

Claim (Index 13):
A steering method for an agricultural vehicle having one or more steerable wheels of a first wheel set, at least first and second steerable wheels of a second wheel set, a steering input device configured to receive a manual steering input for the one or more steerable wheels of the first wheel set, first and second hydraulic steering devices coupled to the first and second steerable wheels of the second wheel set, a valve assembly configured to hydraulically control the first and second hydraulic steering devices in order to steer the first and second steerable wheels of the second wheel set, and a controller, the steering method comprising:\n determining, with the controller, a steering mode of the second wheel set; selectively generating, with the controller, second wheel set steering commands based on the steering mode; providing the second wheel set steering commands to the valve assembly; and hydraulically controlling the first and second hydraulic steering devices with the valve assembly based upon, at least in part, the second wheel set steering commands from the controller; wherein, in a steering assist mode, the second wheel set steering commands are determined based upon, at least in part, the manual steering input; and wherein, in an automated steering mode, the second wheel set steering commands are determined based upon, at least in part, a target path of the agricultural vehicle that is determined independently of the manual steering input; wherein, in a stability mode, the valve assembly is configured to selectively dampen fluid flow between the first and second hydraulic steering devices.
