Abstract

In a method for chassis control of a motor vehicle which has at least one wheel suspension, a vehicle body, and a shock absorber having a rebound stage, whose stiffness is adjustable, and a compression stage, whose stiffness is adjustable, the stiffness of the compression stage is changed for a compressive load of the shock absorber generated by a specific vehicle body movement, and the stiffness of the rebound stage is additionally changed for a subsequently following tensile load of the shock absorber generated by the specific vehicle body movement, or the stiffness of the rebound stage is changed for a tensile load of the shock absorber generated by a specific vehicle body movement, and the stiffness of the compression stage is additionally changed for a subsequently following compressive load of the shock absorber generated by the specific vehicle body movement.
