A steering apparatus for an agricultural vehicle includes a vehicle axle suspended in an oscillating or resilient manner, steerable wheels located on the vehicle axle, and an actuating apparatus for influencing a steering angle which is adjustable on the steerable wheels. A device actively limits an oscillating angle or deflection path arising on the vehicle axle. Moreover, the device operably activates a control unit according to a full steering angle to be anticipated on the steerable wheels as a result of travel.

Steering apparatus for an agricultural vehicle

A system for predictive chassis control including a wheel-spring device controllable with respect to a damping or suspension characteristic, a sensor for ascertaining a force profile of a disturbance acting on the wheel-spring device, and a navigation for ascertaining a current geoposition of the off-road utility vehicle in the form of an associated position data. The system includes a memory unit and a control unit for saving the force profile induced by the disturbance or a quantity derived therefrom. The control unit detects an imminent renewed crossing of the disturbance by continuous reconciliation of the current geoposition received from the navigation with the saved position data. The control unit adapts the damping or suspension characteristic on the basis of the saved force profile or the quantity derived therefrom by a pilot control of the wheel-spring device to compensate for an influence of the disturbance on the wheel-spring device.
