Clutch control apparatus for car

Abstract

Abstract PURPOSE:To enable gear-change control to be carried out smoothly and prevent gear-change shock by interrupting the operation for connecting a clutch when the number of revolutions of an engine is larger than the number of revolutions of an engine is larger than the number of revolutions on the driven side of and the clutch variation rate of the number of revolutions of the engine is positive. CONSTITUTION:A control valve 11 for operating a main clutch 2 and a holding valve 12 are controlled by a control circuit 13. The control circuit 13 is equipped with a revolution number pulse generator 14, clutch switch 16, neutral switch 17, accelerating pedal switch 18, car-speed pulse generator 19, and a pulse generator 20 for detecting the number of revolutions on the driven side of the clutch as input, and provides an output for a servo-amplifier 21. When either of the following conditions is fulfilled, namely if the number of revolutions of the engine is larger than the number of revolutions of the clutch on the driven side or the variation rate of the number of revolutions of the engine is positive, the operation of the clutch 2 towards its connection is interrupted, and the clutch is held at its present position.
