Abstract

A control device for a vehicle power transmission mechanism said control device equipped with a power transmission mechanism (an automatic transmission) having at least an input shaft connected to a drive source mounted in the vehicle and an output shaft connected to the input shaft via a clutch (starting clutch) said control device being capable of adjusting the engagement force of the clutch. The control device is configured such that the clutch output rotation rate of change is calculated (S10 S12) and the engagement force of the clutch is adjusted/corrected so as to decrease the force when the calculated rotation rate of change of the output shaft is a positive value and the engagement force of the clutch is adjusted/corrected so as to increase the force when the calculated rotation rate of change of the output shaft is a negative value (S14 S40). Therefore it is possible to suppress vibration generated by differential rotation of the clutch input/output.
