Abstract

Method for adjusting the damping force of shock absorbers connected between a vehicle body and a wheel at vehicle corners of a motor vehicle, wherein at least one damping force (FLIFT, FPITCH, FROLL) which is referred to a center of gravity of the vehicle body and is divided between axles of the vehicle and between the shock absorbers of the axles is determined as a function of at least one variable which represents a movement of the vehicle body and/or a movement of the respective wheel. For at least one of the damping forces which are referred to the center of gravity of the vehicle body, at least one division factor for the division of the damping forces is calculated between a front axle and a rear axle, and the division of the respective damping force (FLIFT, FPITCH, FROLL) is adapted on the basis of this division factor.
