Trailer stabilization control
Concept
This system supports the driver in stopping the
swinging of a trailer.
The trailer stabilization control detects swinging
and automatically brakes the vehicle quickly to
leave the critical speed range and stabilize the
vehicle-trailer combination.
General information
If the trailer power socket is in use but a trailer
has not been hitched, the system can become
active in certain driving situations, such as when
using a bicycle rack with lighting.
Functional requirement
The system is functional at speeds beginning at
approx. 40 mph/65 km/h while a trailer is being
towed and the trailer power socket is in use.
System limits
The system cannot intervene or not intervene in
time in the following situations, for instance:
▷ If a trailer jackknifes suddenly, for instance on
slippery roads or loose surfaces.
▷ If a trailer with a high center of gravity tilts, be‐
fore swinging is detected.
▷ If DSC Dynamic Stability Control is deacti‐
vated or has malfunctioned.
▷ When the power consumption of a trailer is
too low, e.g., due to tail lights in LED technol‐
ogy, to be detected by the system.
