Control method for engine with valve-lift switching system

摘要

The method involves determining a basic-air flow for two values for a valve stroke of an internal combustion engine based on intake manifold pressure by using a basic-intake manifold type. A switching-relevant pressure region is recognized for switching of valve stroke based on the pressure. A switching cylinder filling is determined based on operating points of the engine for the switching-relevant pressure region by a switching intake manifold type, so that the switching of the valve stroke is operable with constant rotation moment of the internal combustion engine.
