An arrangement includes a first controller which is only switched through to an actuator for a turbocharger if a fault recognition device detects no fault in the operation of the engine. A switchover is made from the first controller to a second controller, if the fault recognition device detects a critical fault. In this connection, the second controller receives a system deviation as an input signal that is different from the one received by the first controller. Thus in the event of a fault, the turbocharger can be controlled in a very flexible manner without the danger that the speed of the turbocharger is increased into its critical range.
