Abstract

A method for controlling a braking system in an all-wheel drive vehicle having a viscous coupling or a viscous lock, wherein a viscous torque acting on a wheel is estimated, the viscous torque is taken into account in estimating a desired braking pressure for the wheel, and the desired braking pressure is applied to the wheel.
