Abstract
A process for controlling an internal combustion engine, whereby the internal combustion engine is equipped with a device to change a valve timing. To permit a change in the valve timing only when it is necessary for the operation of the internal combustion engine, a transmission, connected at the end of the internal combustion engine, is monitored as to whether a shift operation is taking place in the transmission. If such a shift operation is recognized, a change in the valve timing is suppressed.
