SwayControl (Includes Wiring Loom)


Proactive Electronic Sway Control - BMPRO

BMPRO SwayControl is a proactive electronic stability control that can automatically stabilise a caravan/trailer in the event of it’s sway. It automatically corrects caravan/trailer sway which can be caused by changing road conditions, driver error, lateral winds or a passing truck keeping drivers safe on the road.

Electronic sway control is mounted on the underside of the caravan/trailer chassis, wires directly to the trailer braking system and continuously monitors trailer yaw to detect sway. In the event that sway is detected the SwayControl automatically activates the caravan/trailer brakes to bring both it and the vehicle under control.

SwayControl distinguishes between safe manoeuvring and dangerous trailer sway and does not require driver intervention.
With independent control of left and right-hand side trailer brakes, and continual closed loop feedback, the SwayControl quickly and effectively applies the necessary braking force, to the side of the trailer where it is needed to correct trailer sway.

BMPRO offers a range of integration options with prewired looming to enable an easy installation and also integration with the BMPRO Trailsafe Emergency Braking system.
