Abstract
In a method for determining the switchover condition in order to initiate a valve lift changeover in an internal combustion engine, the torque requirement (TQ REQ) is determined. Also, an operational variable of the internal combustion engine, which is representative for an operational state of the internal combustion engine, is determined. According to the operational variable, a duration of time (T), which is required in the current operational state in order to carry out at least one prepared amount for the valve lift changeover, is determined. An alteration value, which is representative for the alteration of the torque condition (TQ_REQ), is determined. The valve lift changeover is initiated by the duration of time (T) and the alteration value (TQ_REQ) according to the torque requirement (TQ REQ).
