For the application of the SHB unit, the control system was useful in the turning of the trailer, especially when making a tight turn or a U-turn. The SHB unit and control algorithm increased the positioning accuracy of the trailer when the tractor was being navigated into a curve.
In addition, the SHB unit could return the trailer 's hitch-point to the centre position so the trailer posture was parallel with the tractor after the U-turn faster compared to the trailer towed conventionally.
