ABSTRACT:
A method for a controlling cylinder valve drive in a piston-type internal combustion engine includes the steps of detecting vibration signals generated during operation by the cylinder valve drive or the cylinder valve, and actuating the cylinder valve drive in dependence on a value of the detected vibration signals which corresponds to the impact time or impact speed of the cylinder valves.
