PURPOSE:To disuse a stroke sensor by estimating an actual clutch speed while modelizing a target clutch speed of an actuator with first-order lag, and integrating it to compute a clutch stroke position. CONSTITUTION:In an electric control unit 27, a target clutch speed for driving an actuator (DC motor) 8 is modelized with first-order lag, to estimate actual clutch speed, further integrating it to compute a stroke position of a clutch 3. The clutch stroke position according to actual movement condition of the clutch 3 is obtained. The positions where the connection actually starts and completes on the clutch 3 are accurately detected, and clutch speed at the time of driving the actuator 8 is optimally controlled under a half-clutch condition. It is therefore possible to speedily and smoothly control clutch connection without using a sensor. |
