The Al-Ko ATC system detects and controls
caravan instability automatically.

AL-KO ATC TRAILER CONTROL 

THE ANTI-SNAKE SYSTEM FOR CARAVANS AND TRAILERS

Al-Ko ATC Trailer Control is an ingeniously simple electronic control system that reacts quickly to maintain the stability of the car and caravan. Al-Ko ATC is similar to the ESP-system on some cars, continually monitoring the stability of the car and the caravan.  Al-Ko ATC is similar to the ESP-system on some cars, continually monitoring the stability of the caravan during a journey and only operates when an unstable condition is encountered.  When Al-Ko ATC activates, the driver will feel the vehicle being slowed down by the soft braking of the caravan.

Anyone who has experienced the "snaking" effect when towing a caravan, knows how sensitively an outfit can react at higher speeds.  Any slight evasive action, side wind or turbulence from overtaking a heavy goods vehicle, can quickly create an unstable driving condition that results in the loss of control of car and caravan.  When this happens the results can be devastating.

ELECTRONIC TRAILER STABILISING

Lateral acceleration sensors in the Al-Ko ATC unit, monitor for slight sideways movements or a large swinging motion of a caravan.  Even before an ESP system has detected the swinging movements of the car, Al-Ko ATC applies the brakes on the caravan to slow the outfit down, before the situation becomes critical.  The braking operation lasts only for a few seconds, long enough to re-establish control and to bring the car and caravan back to a safe driving condition.

CONFIDENCE AND CONTROL

Al-Ko ATC is a passive emergency safety system that connects to the car via the normal 12S and 12N connection cables.  When the system is 'plugged in' the Al-Ko ATC automatically starts a 'pre-flight' test that engages the plunger, applying the caravan brakes.  Once this test is complete, the LED warning light on the front fairing changes from red to green to indicate the system is monitoring the caravan and in a 'ready for travel' state.
