Claim:
1. A method for controlling an active suspension system of a motor vehicle said method comprising: providing an active suspension system having actuators and electromechanical controllers, said actuators including at least one spring and at least one damper, wherein a respective one of the electromechanical controllers is assigned to each one of the actuators and cooperates with the one of the actuators, each of the electromechanical controllers being connected with at least one electrical energy storage of the motor vehicle via an onboard network of the motor vehicle; during a driving maneuver of the motor vehicle operating at least one of the electromechanical controllers either as a generator or as a motor, wherein when the least one electromechanical controller is operated as a generator the at least one electromechanical controller during the driving maneuver generates electrical energy, whose amount has a negative value, wherein when the at least one electromechanical controller is operated as a motor the least one electromechanical controller during the driving maneuver consumes electrical energy, whose amount has a positive value; subtracting a value for an amount of electrical energy converted by the suspension system in an actually performed 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 the 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.
