A system and method for monitoring the control of an engine having at least two control units, which is constructed of at least two cylinder rows or of two partial engines is provided. A control unit is assigned to each cylinder row or each partial engine, which control unit, on the basis of detected operating parameters, controls the function of the respective cylinder bank assigned to it or of the partial engine assigned to it. The control units mutually exchanging their control variables, and the detected operating parameters and the control variables emitted by the control units being monitored jointly to determine their credibility.
