ABSTRACT:
The invention is directed to an arrangement for rapidly adjusting an electromagnetic load associated with internal combustion engines. The output signals of two control systems are combined in a logic circuit such that priority is assigned to one of the two control systems. Dependent on the output signal of the higher-order control system, an evaluation circuit acts on a switch arrangement to thereby suitably influence the signal resulting from the combining operation of the output signals of the two control systems. This arrangement makes it possible to speed up the delivery of the output signal of the higher-order control system to the electromagnetic load which may be an injection valve, for example. The higher-order control system may be a smooth-running control system.
