Abstract (en)
[origin: US4887570A] In a system for regulating the idling speed of rotation of an internal combustion engine, in which a correction variable, which is determined by comparison of the speed-of-rotation actual value which is fed as speed-of-rotation signal with a speed-of-rotation desired value, is fed to a control member, a predetermined correction variable is fed upon the absence of the speed-of-rotation signal to the control member. Furthermore, it can be provided that a signal (idling signal) which is dependent upon whether the gas pedal is in the idling position is fed, that in the absence of the idling signal the actual speed-of-rotation value is not used for the determination of the correction variable, and that a predetermined correction variable is fed to the control member when the idling signal is not present and the desired speed-of-rotation value is smaller than the actual speed of rotation value for longer than predetermined periods of time and the starting value (opening of the control member upon the starting process) is not greater than the regulating value.
