Abstract
In one aspect, a method for controlling an internal combustion engine using valve lift switchover is provided. Within the scope of this method, a switchover intake manifold model for the switchover-relevant pressure range for valve lift switchover is applied in addition to the use of a basic intake manifold model. This ensures a valve lift switchover with approximately constant torque of the internal combustion engine.
