Abstract
An automatic stability control system is provided which determines the lateral acceleration and lateral velocity of a towed trailer and forward velocity of the tow vehicle. When the lateral acceleration and/or velocity of the towed trailer exceeds predetermined values established for the current forward velocity of the tow vehicle, the stability system meters a gas, such as compressed air, from a gas reservoir into at least one cylinder of a pair of buffer arms each comprising a piston that is pivotably attached to the towed trailer and a cylinder which is pivotably attached to the tow vehicle. Gas is metered into one or both buffer arm cylinders until the lateral acceleration and lateral velocity of the towed vehicle meets or is below predetermined values established for the forward velocity of the tow vehicle.
