JPS5730624A - Electromagnetic clutch controller for vehicle - Google Patents

Abstract

PURPOSE: To alleviate shocks when changing speed in such a way that the time for the clutch on its half way is controlled in proportion to treating of an accelerator pedal, in an electromagnetic clutch for vehicle to transmit its power.

CONSTITUTION: Speed change signal (a) which is generated by controlling a shift lever turns off a transistor 41, charges a capacitor 43 while output voltage (d) rises up with the lapse of time. Then, as an accelerator pedal is stepped on, clutch hold signal (b) grows to a high level, it is inverted to a low level signal (b') in a reference voltage generating circuit 49, and when it becomes the same as the prior signal (d), it gives signal (e), which releases half-way clutch signal (j) that is synthesized by vehicle speed signal (c) and output (f) from an oscillatory circuit 53. At the time of low treading, since the clutch hold signal (b) turns to a low level, output from the reference voltage generating circuit 49 grows to a high level (b"), the time which corresponds to the signal (d) becomes longer, therefore it becomes a long half-way clutch time.
