Abstract
A method for controlling an active suspension system which includes at least on spring and at least one damper as actuators and electromechanical controllers which are assigned to the actuators and can be either operated as a generator or as a motor. The method includes subtracting a value for an amount of electrical energy converted by the suspension system in a driving maneuver from an actual value of electrical energy stored in the electrical energy storage, thereby forming a differential value; comparing the differential value with at least one threshold value; when the differential value is greater than a maximal threshold value and at least a first one of electromechanical controllers is operated as a generator, operating at least one second one of the electromechanical controllers as a motor, wherein at least a portion of electrical energy which is generated by the at least one first electromechanical controller is simultaneously converted by the at least one second electromechanical controller into mechanical energy.
