Abstract

A device for controlling an operating characteristic of an internal combustion engine is suggested with a speed limitation being effective according to a predetermined time function by influencing the fuel metering during the transition from the idling state to the driving mode. This speed limitation is activated especially in the event of a fault of the actuating device, of its activation and of the feedback and in the event of a speed response critical to safety in the idling state.
