Tow safely with proactive electronic SwayControl.

BMPRO SwayControl is a proactive electronic stability control that can automatically stabilise a caravan/trailer in the event of its 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 maneuvering 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.

Prewired looming to enable an easy installation and also integration with the BMPRO Trailsafe Emergency Braking system is supplied with the electronic SwayControl.

The SwayControl contains a gyro inside the unit. When the gyro detects a .4 G force movement, it will apply the correct brake force to the side of the sway.

The SwayControl will enter off-road mode, when the up and down forces detected by the SwayControl are constant and are longer than 5 seconds.

The caravan/trailer must be equipped with a 12V battery system of greater or equal to 50Ah.
