Yaw Moment Compensation When Braking On A Road Surface With Non-Uniform Traction
WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2006 BMW 530i, 2006 BMW 525i, 2006 BMW 330xi, 2006 BMW 330i, and 2006 BMW 330Ci. However, it is still accessible from the selected car via links, so may be relevant.
E90/E91
On the E90/E91, Active Steering offers an additional function for driving stabilization. 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 stabilizing the vehicle.
Compared to pure ABS control, Active Steering with yaw moment compensation shortens the braking distance.
The driving stabilization 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.
