CONTROL DEVICE OF HYBRID VEHICLE

PROBLEM TO BE SOLVED: To provide a control device of a hybrid vehicle that can improve fuel consumption while suppressing degradation of drivability when an electric motor is driven with surplus torque of engine output torque to generate power.SOLUTION: In control of charging by the electric motor MG using the surplus torque of the engine output torque to request torque, as a transmission gear ratio γ of an automatic transmission 18 is greater, a limit value of an amount charged by the electric motor MG is smaller. Thus, in a drive state in which an error between the request torque and the engine output torque tend to influence acceleration, and the transmission gear ratio γ of the automatic transmission 18 is comparatively greater, the occurrence of sense of incongruity can be suppressed by reducing the limit value of the charged amount, and, in a drive state in which the transmission gear ratio γ is comparatively smaller, improvement in fuel consumption can be achieved to a maximum level.
