Abstract: A suspension system for a vehicle includes a shock absorber unit operably coupled between a vehicle body and a wheel carrier. The shock absorber unit includes a first damper unit having a first cylinder chamber, a second damper unit having a second cylinder chamber, a first piston connected to a first piston rod, a second piston connected to a second piston rod, and an adjusting unit. The first and second cylinder chambers may each be filled with a fluid. The first and second cylinder chambers may be formed in a common cylinder unit and sealed off from one another. The first and second piston rods may be arranged axially displaceable in the first and second cylinder chambers, respectively. The first piston rod is operably coupled to the vehicle body and the second piston rod is operably coupled to the wheel carrier. Damping actions of the first and second damper units are changed independently of one another by the adjusting unit.

Abstract: The disclosure relates to a method to estimate dynamic loads acting vertically on a rear axle of a motor vehicle during a forward driving operation. To enable an estimation of the dynamic loads acting vertically on the rear axle during the forward driving operation of the motor vehicle cost-effectively, the dynamic loads are estimated in consideration of dynamic mechanical forces engaging vertically at a front axle of the motor vehicle during the forward driving operation. In addition, dynamic acceleration forces engaging at a spring mass of the motor vehicle during the forward driving operation are also considered when estimating the dynamic loads during the forward driving operation.
