AUTOMATIC CLUTCH CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To establish a proper standby condition irrespective of varying temp. of a lubricating oil in a transmission. SOLUTION: The standby position CRCO is set on the basis of the input shaft revolving speed of a transmission (SS2) while the transmitted torque of an automatic clutch is changed immediately after the start of an engine, and the T/M oil temp. TT/M at this time is put in memory as the reference temp. t0 (SS3). To prevent the input shaft revolving speed in the standby condition from becoming excessive resulting from a drop of the lubricating oil viscosity associated with a temp. rise, the standby position CRCO is corrected bit by bit so that the transmitted torque of the automatic clutch lessens (SS8 and SS9) when the T/M oil temp. TT/M (=current temp. t) is ultra-low not more than the specified value (a) and the temp. change (t-t0) is not less than specified value (b).
