Abstract (en)

[origin: US4471735A] In an idling controller, particularly for automotive vehicles, there are present both a control amplifier with integral time portion (3) and a limiter (6) with proportional time portion. The inputs of the limiter are acted on by the correcting variable from the output of the control amplifier and by a limiter reference variable formed with the actual-speed value. The output of the limiter is fed back to an input of the control amplifier. In order to obtain the desired time action of the idling controller upon sudden drops in speed, at least one time member (12) with differential time portion is provided between the input (1) of the actual-speed value and the output of the limiter (6). The limiter (6) is so dimensioned and coupled with the output of the control amplifier (3) that, upon a drop in speed beyond a predetermined value, the correcting value (y) is controlled by the output variable of the limiter (6) (control limit).
