Yaw-Moment Compensation When Braking On A Road Surface With Non-Uniform Traction

WARNING: This page is about a different car, the 2007 BMW 550i and 2006 BMW 550i. However, it is still accessible from the selected car via links, so may be relevant.

> BMW 1 and 3-Series

Active Steering now has an additional function for driving stabilisation.

With conventional systems, the driver has to actively steer the vehicle in a straight line if the brakes are applied on a road surface with non-uniform traction levels.

In such situations, the Active Steering performs this active steering intervention, so stabilising the vehicle.

Compared to pure ABS control, Active Steering with yaw moment compensation shortens the braking distance.

The driving stabilisation function of the Active Steering can be deactivated together with DSC with the DTC button (when DSC is completely deactivated). Together with the hydraulic power steering, the variable steering-gear ratio is always active.

> From X5 (3rd generation)

This function is completely integrated in the Active Steering control unit. Other model series will follow later.
