The Original Knott ETS Plus guarantees driving safety of your caravan. Our industry-tested stabilisation system recognises potential swerve risks early and brakes car and caravan with precision. So your journey is not only beautiful but also safe!

We are experts in the manufacturing of caravan trailers. Therefore, the Original KNOTT ETS Plus is perfectly tuned to all KNOTT chassis – now including all AL-KO chassis.
Up-to-date sensors and high-performance materials ensure the highest degree of safety, longevity and reliability.


The integrated sensor of our Original KNOTT ETS Plus constantly monitors the movements of the car/caravan combination with perfect technological precision. A special software evaluates the data in real-time – so that, for example, while crossing bumps or similar obstacles, the brakes are not activated. However, when the situation becomes critical, the software reacts at lightning speed. This is ensured by our own algorithm which initiates the braking process within a fraction of a second and effectively counters the swerve.

Why is travelling with Knott simply safer?

5 questions for the developer of ETS Plus:
M.Sc. Eng. Josef Strasser and
Mechanical Engineer Christian Mertinko


Why do caravans swerve so easily and why does this present a grave danger?

Josef Strasser: Any car/trailer combination becomes unstable with increasing speed. Even if a caravan was optimally loaded and secured, sudden wind gusts, the wake when overtaking a truck or road bumps may cause uncontrolled swerving. One of the most frequent causes are downhill gradients, by the way. When the road becomes steep, the weight of the caravan starts to push against the vehicle. The combination becomes unstable and extremely vulnerable to side winds or surface bumps. In the worst scenario, all this may lead to uncontrolled driving and the caravan tipping over!

And how does ETS Plus make caravan driving safer?

Christian Mertinko: A special sensor permanently monitors the movements of the car/caravan combination. When it recognises a clearly critical situation, ETS Plus reacts within a fraction of a second and initiates a controlled brake process. This will literally protract the car/trailer combination and stabilises it immediately while ETS Plus simultaneously reduces the speed. Danger averted.

How can I generally prevent such critical situations?

Josef Strasser: Loading the caravan correctly is extremely important. The more of the load is located around the axle, the lower is the probability that the car/trailer combination will oscillate. The correct support load is also important. And of course sensible speed. After all, already the journey is for caravan owners a piece of holiday.

What kind of caravans is the ETS Plus suitable for?

Christian Mertinko: At KNOTT, we have been developing chassis for caravans as well as axles and brakes since 1997. So we know exactly what we do. Therefore, ETS-Plus is perfectly suitable for KNOTT and AL-KO chassis, i.e., for all caravans. Since it is a high-quality original product manufactured by KNOTT, it can be easily integrated into the existing caravan system.

What else should I know about ETS Plus?

Josef Strasser: Some of our products are also reliably used in professional areas. We, for instance, manufacture brake solutions for tractors, large trailers, construction machinery or airport equipment, and those depend on absolute safety, reliability and longevity. Naturally, we incorporate all this expertise in our products for caravans. Like all our developments, the ETS Plus is of industrial quality that our customers can rely on!

Christian Mertinko: The quality of our products does not only extend to the technology but also to the materials used. Despite all leading-edge safety technology, we are also committed to ensure that caravan owners can enjoy our ETS Plus for a long time. Therefore, we intensively focused on the materials used while developing the ETS Plus. The high-performance materials used which are also used in the industry are ultra-light and resistant to corrosion. This saves costs in the long run!

Original Knott

Better from experience

We started our ideas already in 1937. For example, with brake solutions which are being used in the harshest conditions in the industrial and agricultural sector. We employ these experiences for our Original KNOTT trailer technology today.

One for all

Since 1997, we have been manufacturing axles, brakes and chassis for caravans – in proven and especially safe industrial quality. Our electronic stabilisation system ETS has been available since 2009. The new Original KNOTT ETS Plus is also perfectly suitable for all KNOTT and AL-KO caravan chassis and ensures safe stability while travelling. For everyone.
