Abstract (en)
[origin: WO0031384A1] An assessed value (FG,AV,0) of an interfering force resulting from the gas forces which influence the gas exchange valve immediately before it opens is calculated. The time history (FG,AV,t) of the interfering force, which is produced on the gas exchange valve after it has begun to open, is assessed based on the step response of a transmission member to a step change of the interfering force from the assessed value (FG,AV,0) to a predetermined value. An actuating signal for the actuating drive is determined in dependence on the time history of the interfering force.
