ABSTRACT:
In a safety device for electronic velocity control or regulating systems for motor vehicles with idling regulation in which a desired value can be fed to a setting device for the power of the engine of a motor vehicle and in which the setting device comprises a setting controller, an output stage and a setting member, there is provided a switch device which prevents the regulating of the output stage in a direction towards an opening of the throttle valve as a function of an output signal of a comparator. An actual-value signal corresponding to the position of the throttle valve and a limit value can be fed to the comparator, the limit value, at least upon a disconnection of the control or regulation, assuming a value necessary for idling control.
