Abstract

A method for detecting a defective damper device of a vehicle, including the following steps: monitoring the specific damper travel values (DW) of at least two wheel carriers of the vehicle in a monitoring period (UZ), determining the specific damper speeds (DG) and the specific damper accelerations (DB) on the basis of the monitored specific damper travel values (DW) in the monitoring period (UZ), acquiring the specific damper work values (DA) on the basis of the determined specific damper speeds (DG) and on the basis of the determined specific damper accelerations (DB), generating a comparison result (VE) from a comparison of the acquired specific damper work values (DA) with one another, and generating at least one specific status signal (SS) on the basis of the comparison result (VE) for the at least two wheel carriers.
