Abstract
A hydraulic steering system () includes a steering command device () having a steering sensor (), a steering motor (), a wheel sensor (), a pressure source (P), and control means () controlling a fluid supply from the pressure source (P) to the steering motor (), wherein the control means () has an open loop control (). Such a steering system should have a good relationship between steering input from the operator and steering behaviour of the vehicle to be steered. To this end the control means () include in addition to the open loop control () a closed loop control (), wherein cross-over transition means () are provided which are connected to the open loop control () and to the closed loop control () and control a transition between the open loop control () and the closed loop control ().
