Abstract: A controlling map is produced for the clutch control to lessen the starting jerk and the friction work through analyzing the engagement, on basis of practical application demand. The algorithm has the advantages of strong adaptability and less calculation for single chip microcomputer to use. It is applied to Santana model AMT, not only can stable starting be realized and service life of the clutch is also prolonged.
