Active Yaw Control

Active Yaw Control, also known as yaw control, contributes as a driver assistance system significantly to a more dynamic driving behavior. Is an intelligent drive system which sits on the driving axle.

Conventional alternatives

Open differential

A conventional differential gear allows cornering by allowing different speeds of the two drive wheels. It transmits the drive torque equally to both wheels. This also means that the wheel with the better adhesion has only so much traction, as that is on slippery surfaces or lightly loaded during cornering is.

Differential lock

To increase traction and improve vehicle dynamics, a differential lock are used that the two drive wheels partially connects via friction. Thus, even traction on the wheel are transmitted with better liability if the other wheel has little grip. However, since in this case the two drive wheels to each other to a certain extent locked cornering is difficult, the vehicle gets thereby an understeering tendency. Skilled sport riders, the understeer tendency deal by ' throw in the curve ' the vehicle and give quite early gas. Since when cornering, the inside wheel is unloaded, is driven when accelerating with differential lock the outside wheel stronger and thereby generates a directed graph in the yaw moment. This driving technique is not applicable on public roads in the normal case.

Controlled Differential Lock

Through controlled differential locks, the Kurvenwilligkeit an open differential with the improved traction of a locking differential can be combined. By an intelligent logic, considers the current driving state, the differential is closed only to the extent as required by the driving situation. Nevertheless, a controlled differential lock can make a voluntary winding the vehicle only in certain exceptional situations.

Active Yaw Control

The particular advantage of Active Yaw Control system is that such a system can produce the desired yaw moment in every situation, even with the clutch pedal because it transmits the braking torque on the one hand as a driving torque to the other side. It can act agilisierend or stabilizing therefore as required.
