Method for controlling an electromechanical actuating drive for a gas exchange valve of an internal combustion engine

摘要

An estimated value is calculated for a disturbing force which occurs as a result of the gas forces acting on the gas exchange valve immediately prior to the opening of the latter. The time profile of the disturbing force resulting at the gas exchange valve after the commencement of opening is estimated from a response of a transfer member to a jump in the disturbing force from the estimated valve to a predetermined value. An actuating signal for the actuator drive is determined as a function of the time profile of the disturbing force.
