Claim:
1. A method for operating a wheel suspension system of a motor vehicle, comprising: ascertaining by a sensor a ground to be traveled in the future by the motor vehicle; checking the ground for the presence of an obstacle; identifying an unevenness as the presence of the obstacle, when a value of at least one measurement of the unevenness deviates by a tolerance value from a threshold value; predicting for the identified obstacle a first value for an amount of electrical energy which is converted from mechanical energy by an electrical machine of the motor vehicle operated as a generator, when a damping ratio is set with a defined recuperation value for a damper via which a wheel is connected to a chassis of the motor vehicle, as the motor vehicle drives over the identified obstacle; predicting a second value for a ride comfort by setting the damping ratio with the recuperation value for the damper, as the motor vehicle drives over the identified obstacle; determining a third value for a decision criterion as a function of the first value and of the second value; and driving over the identified obstacle with the recuperation value set for the damping ratio of the damper, when the third value corresponds to a target value.
