An electric stability control system and device for controlling sway stability of a caravan or trailer and the like.

摘要

A system for substantially minimising sway of a towed vehicle, fitted with electric brakes, hitched to a towing vehicle, the system including an electric stability control (ESC) device adapted for mounting to a portion of the towed vehicle, the ESC device being operably connected to the electric brakes by cable means, the ESC including a sway detecting means for measuring lateral acceleration of the towed vehicle; an actuator means for activating the electric brakes of the towed vehicle, the actuator means being operatively connected to the sway detecting means whereby the sway detecting means activates the actuator means to apply a voltage to the brakes for a period of time when the sway detecting means detects a predetermined lateral acceleration of the towed vehicle relative to the towing vehicle. The system can also be used for controlling dangerous sway and instability of a towed vehicle.
