JOS (joystick steering) makes it possible to remote-control a hydraulic steering axle via electronic joystick in conjunction with hydraulic proportional valves. The system can be used in parallel with a mechanic-hydraulic steering system (orbitrol) and be activated with it by means of toggle switching. Installation as an independent steering system, without an orbitrol, is also possible. Simultaneous, combined operation with the orbitrol is thus not possible with joystick steering, unlike a superimposed steering system (EAS).
The joystick can be used to specify the steering speed at the vehicle axle. Depending on the sensors that are also available in the vehicle, it is possible to adjust the amplification between joystick deflection and steering speed flexibly to suit the particular driving situation.
With JOS, a convenient steering system can be set up for use on the construction site, on the business premises or in the field. An additional driving direction selection switch can be installed.
As well as the steering speed being specified via the joystick signal, there is an interface to the vehicle CAN bus that makes it possible to specify the steering signal by means of standardized commands in accordance with the ISOBUS standard. This means that sensor-based steering assistance systems can be realized.
