Abstract
PURPOSE: To prevent a drop of engine rotation being caused when turning to idle rotation control by connecting a rotation switch and an idle switch with a logical operation circuit prepared between a rotation detector and a comparator.
CONSTITUTION: A logical operation circuit J is connected with an output terminal of rotation detector A, the output of said circuit J is put out to a comparator B and besides a rotation switch K and an idle switch D are connected to the circuit J, a switch K is connected with the detector A and the switch D. In case the switches D and K are OFF, the output is L, namely an open loop. Again, when the switch D turns ON and the switch K turns ON, the detector A has no hysteresis being connected with the comparator B with M rotation to perform the rotation conrol (ISC). Further, the rotation range, wherein ISC is performed when the switch K puts out the signal ON, has hysteresis in the case of ON and OFF and the comparator B performs an operation to do ISC in the fixed rotation range.
