Claim Text:
1. An apparatus for controlling a vehicle power transmission mechanism having a drive source mounted on a vehicle, a transmission equipped with at least an input shaft connected to the drive source, an output shaft connected to the input shaft via a speed ratio changing mechanism, and a clutch transmitting a rotation of the output shaft to driven wheels, and a clutch engaging force regulator that regulates engaging force of the clutch of the transmission, the vehicle power transmission mechanism being configured to transmit driving force outputted from the drive source to the driven wheels through the input shaft, the output shaft, and the clutch whose engaging force is regulated by the clutch engaging force regulator, comprising: a clutch output rotation change rate calculator that calculates an output rotation change rate of the clutch based on a differential value of a rotational speed of an output shaft of the clutch; and a clutch engaging force corrector that corrects the clutch engaging force regulated by the clutch engaging force regulator to decrease when the calculated output rotation change rate of the clutch is a positive value, and corrects the clutch engaging force to increase when the calculated output rotation change rate of the clutch is a negative value.
