AL-KO ESC - The safety and stability system for caravans with electric brakes. 

AL-KO ESC is a sophisticated electronic brake actuation system that automatically responds to the driving behaviour of the caravan by monitoring for any dangerous lateral movements and taking preventative action immediately – applying the caravan’s electric brakes to maintain road position.

How AL-KO ESC Works

The AL-KO ESC system is engineered to operate when it identifies critical driving situations - such as a build-up of two small swings, or one large, sudden lateral movement. The lateral acceleration sensors inside the AL-KO ESC unit monitor for these repeated side movements or large swings. AL-KO ESC continuously evaluates the data and when critical lateral movements are recognised, ESC activates and applies the brakes immediately to bring the vehicle back into line in a smooth and controlled manner. Applying the brakes on the caravan immediately straightens the car and caravan and prevents any further oscillation.

AL-KO ESC is positioned behind the axle of the caravan or trailer at the point where lateral movement can be measured consistently between different caravans. Once the combination is stable, the AL-KO ESC deactivates the brakes. AL-KO ESC then immediately continues to monitor for critical situations. The brakes are applied for as long as necessary, until no further lateral movement of the trailer or caravan is picked up. AL-KO ESC then immediately continues to monitor for critical situations.
