ABSTRACT:
An automatic clutch control system including a clutch, a clutch actuator for controlling a clutch stroke, a plurality of solenoid valves for controlling the clutch actuator, a clutch stroke sensor for measuring the clutch stroke, a control unit for feeding back a stroke signal detected by the clutch stroke sensor and for controlling the solenoid valves to control clutch engagement and disengagement. The control unit includes a learning control section for storing a full clutch engagement point upon saturation of the stroke signal in a clutch engagement operation and storing clutch contact point upon start of rotation of an engine input shaft in a clutch engagement operation following a clutch disengagement operation. Based on the full clutch engagement point and clutch contact point, the control unit judges a clutch operation range for control of clutch engagement and disengagement.
