ABSTRACT:
An emergency operation device for a microcomputer-control system, in particular an idling charge regulating means in a motor vehicle, has a microcomputer which has both a signal output for emitting control signals generated by the microcomputer and a further output for emitting regular failsafe pulses. A failsafe circuit monitors the regular occurrence of the failsafe pulses. Upon the occurrence of a failsafe signal from the failsafe circuit, a reset input of the microcomputer is actuated, and at the same time the system is supplied via a logic block with an emergency operation signal from an emergency operation function generator.
