AXS (auxiliary steering system) enables control of one or two auxiliary steering axles via electro-hydraulic proportional valves. Depending on the machine’s specific electronics architecture, the software is available as an individual application on controllers HY-TTC 90CM and HY-TTC 32S or as a library module on an HY-TTC 580.
The current steering angle is detected by means of the reference axle (generally the main steering axle) and the target angle for the auxiliary steering axle(s) is calculated on the basis of the set steering type and the selected steering mode.
The auxiliary steering axles are adjusted/moved to the target position electro-hydraulically. Position and/or angle sensors are needed to detect the current position at each axle.
