Abstract
A method for operating a hydrostatic steering device for an agricultural utility vehicle, includes controlling a steering orbitrol of the hydrostatic steering device by a steering wheel via a steering column, deflecting a steering cylinder in accordance with a driver-side steering actuation of the steering wheel, detecting a steering actuation variable via a first sensor, detecting a steering position variable via a second sensor, in a normal operating mode, the control unit is configured to actuate the electric drive unit such that an actuating torque which increases continuously with the wheel steering angle is generated at the steering column and thus at the steering wheel, and in an emergency operating mode, the control unit is configured to control the electric drive unit such that an actuating torque is generated on the steering column and thus on the steering orbitrol to support driver-side steering actuation.
