<p>PURPOSE:To improve the warming-up characteristic of engine speed at a cold time by learning a half-connected clutch point and, then, disconnecting a clutch until a certain time elapsed when the water temp. is lower than a defined value, in the clutch control device of an electronically controlled automatic transmission. CONSTITUTION:When a water temp. sensor 5 as a detecting means for detecting the cooling water temp. of an engine 1 detects that the cooling water temp. is lower than a defined temp, a water temp. switch 10 is turned on, and, as the cooling water temp. rises, the water temp. switch 10 is turned off. A control unit 11 consisting of an electronic control device receives signals from the water temp. sensor 5, an engine rotation sensor 6, an input shaft rotation sensor 7, a clutch stroke sensor 8, and a select position sensor 9 and controls a select actuator 3a and a clutch actuator 4. The control unit 11 also has a timer 11a which is a time measuring means for measuring a time after the engine is started.</p> |
