A device and a method are provided for regulating the lift characteristic of a charge cycle valve of an internal combustion engine. The device comprises a controllable drive unit having an actuator element for actuating the charge cycle valve, two energy storage means acting on the charge cycle valve in opposite drive directions and a regulating means for controlling the drive unit. The regulating unit controls the drive unit according to a stored setpoint path, on the basis of which the charge cycle valve is transferred from a first end position into a second end position and vice versa. The setpoint path is designed so that it maps the ideal transient characteristic of the energy storage-drive element-energy storage system of the device without taking any additional ambient influences into account.
