Abstract: A hydraulic steering system (1) is described. The hydraulic steering system (1) comprises a steering motor (2) and a joystick (3) having a housing (4), a handle (5) mounted movably to the housing (4), a handle angle sensor (6) and return to center means (7) producing a restoring force on the handle (5).
Such a system should help an operator to steer a vehicle in a safe manner.
To this and the return to center means (7) comprises an input (8) for a parameter of a vehicle to be steered and produces a variable restoring force depending on a signal at the input and/or of an angle of the handle (5).
