摘要： A method for calibrating a fully hydraulic steering system (1) of a vehicle having steered wheels and a hydraulic steering motor (2) is described, in which method the steered wheels are moved by the steering motor (2) in one direction until they reach a first end position and are then moved in the opposite direction until they reach a second end position, wherein the hydraulic steering system (1) comprises a wheel angle sensor (15, 16) determining the wheel angle of the steered wheels.
Such a calibration should be performed in a simple way.
To this end the wheel angle sensor (15, 16) determines a first signal in the first end position and a second signal in the second end position wherein a neutral position of the steering motor is determined by determining a neutral signal between the first signal and the second signal, wherein the difference between the neutral signal and the first signal is substantially equal to the difference between the neutral signal and the second signal.

摘要： A method for controlling steering of a vehicle (1) is provided, the vehicle (1) defining two or more steerable axes, and the vehicle (1) comprising a number of wheels (2), each of said wheels (2) being associated with one of said steerable axes in such a manner that steering of a given wheel (2) is obtained by steering the steerable axis associated therewith. The method comprises providing a first, a second and a third steering input. The first steering input defines a point of intersection between a virtual steering axis (4) and a longitudinal centre axis defined by the vehicle (1). The second steering input defines an angle between the virtual steering axis (4) and the longitudinal centre axis. The third steering input defines a position of a centre of rotation (5) along the virtual steering axis (4). A position for each of the steerable axes defined by the vehicle (1) is calculated, which causes the vehicle (1) to rotate about the centre of rotation (5) defined by the first, second and third steering inputs, and each of the steerable axes is moved to the calculated position.

摘要： A method for testing an electro-hydraulic steering system (1) of a vehicle is described, the system (1) having two parallel branches (4, 5), wherein each branch (4, 5) is able to control the steering of the vehicle system (1) comprising a main electric power supply (20) connected to both branches (4, 5), wherein at least one of the branches (5) is connected to a backup battery (25).
The backup battery should be tested in a simple way.
To this end testing is performed by disconnecting the main electric power supply (20) from this branch (5) and using this branch (5) as test load of the backup battery (25).

摘要： A hydraulic steering system (1) is described, the system (1) comprising a steering command device (2) having a steering sensor (3), a steering motor (6), a wheel sensor (9), a pressure source (P), and control means (12) controlling a fluid supply from the pressure source (P) to the steering motor (6), wherein the control means (12) comprise an open loop control (19).
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 (12) comprise in addition to the open loop control (19) a closed loop control (20), wherein cross-over transition means (21) are provided which are connected to the open loop control (19) and to the closed loop control (20) and control a transition between the open loop control (19) and the closed loop control (20).
