ABSTRACT:
A control system and calibration method are provided for a vehicle drive line having an automated master friction clutch. The control system utilizes engine torque data supplied by a serial communication data link to identify a clutch control parameter value corresponding to an urge-to-move position of the clutch. The clutch control parameter value identified by the calibration method is stored and utilized by the control system to control the engagement position of the automated clutch in an “urge to move” mode of operation. The inventive calibration method can be utilized across multiple vehicle platforms having different engine, clutch and transmission system components.
