Abstract
A control apparatus for a vehicle that including a drive-force transmitting apparatus and a hydraulic control unit. The drive-force transmitting apparatus defines a drive-force transmitting path through which a drive force is to be transmitted by a continuously-variable transmission mechanism when the drive-force transmitting path is established by engagement of an engagement device. An electromagnetic valve of the hydraulic control unit regulates a hydraulic pressure supplied to the electromagnetic valve via a hydraulic passage, such that the regulated hydraulic pressure is supplied toward the engagement device. An accumulator of the hydraulic control unit is connected to the hydraulic passage, so as to store the hydraulic pressure that flows through the hydraulic passage. The control apparatus calculates, based on a storage state of the hydraulic pressure in the accumulator, an input torque inputted to the continuously-variable transmission mechanism when the engagement device is in a releasing process state.
