A controller for a hybrid vehicle capable of making a first control rule and a second control rule cooperate with each other is provided. In the first control rule, a gear ratio is controlled such that output from an internal combustion engine via a transmission satisfies requested drive power. In the second control rule, the gear ratio is controlled such that a sum of drive power by a motor and drive power by the internal combustion engine becomes the requested drive power. A device (30) for controlling a hybrid vehicle that includes an internal combustion engine (11) and a motor (13) as power sources capable of generating drive power for a wheel (18) and is provided with a transmission (12), a gear ratio of which is controlled according to the first control rule, between the internal combustion engine (11) and the wheel (18), calculates a target gear ratio according to the second control rule and determines a parameter (vAp) used in the first control rule on the basis of the target gear ratio such that a sum of drive power (Fm) by the motor (13) and drive power (Fe) by the internal combustion engine (11) becomes requested drive power (Fd).
