ATC keeps the caravan or trailer securely on track!

The ATC is ingeniously simple.

In circumstances that cause the trailer to snake, the lateral acceleration sensors capture the slightest side movements of the ATC control electronics, even before any ESP in the car is able to register the swinging movements of the car.  The trailer is braked immediately - without the driver's influence.  A few seconds of braking power are sufficient until the car and caravan are in a safe driving state again.  Controlled braking is carried out by the caravan brakes.

The Al-Ko ATC anti-snake system can be operated in addition to ESP systems offered by some car manufacturers.

ATC Trailer Control is a one-off investment with which you achieve constant maximum safety when driving with a car and caravan/trailer.




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.

Can ATC be retrofitted to my caravan? Yes, ATC is retrofittable to most caravans with an Al-Ko chassis.

750 - 1000 kg
1001 - 1300 kg

500 kg
800 kg

Where does ATC get its power from? ATC is connected to the caravan distribution box and the supply is provided by the constant live (pin 4) from the grey 12S plug.

1301 - 1500 kg

1000 kg

How much power does ATC require? When ATC is activated, it instantly draws 15 amps and must take priority over any other 12 volt equipment using the same pin - ie caravan battery charger.

1501 - 1800 kg

1100 kg

Can ATC also be fitted on caravans
with a (7-pin) plug?
Yes.  The system requires the use of electrical connections from the 12S (grey) plug.  It also works with caravans fitted with the new 13-pin plug.

1300 - 1600 kg

1000 kg

Where does the LED need to be fitted? Near the overrun device on the front fairing.

1601 - 2000 kg

1200 kg

Do the brake lights function when ATC is activated? No.  The ATC brakes the brakes the caravan and car softly.  The driver will feel when ATC has activated.

2000 - 2500 kg

1600 kg

Does ATC need maintenance? No.  The system is maintenance free.


How do I know that ATC is ready to use? As soon as the 7-pin plug is connected to the towing vehicle, the ATC completes a pre-flight test.  The function status is shown via a green LED on the overrun device.
Green (or flashing green) = ready for use.
Red = ATC not functioning, but car can be driven.
Flashing red = caravan brakes are applied.  Car and caravan should not be driven.

How do I recognise that ATC emergency system is working in the car? Soft braking is noticed in the car.
