Claim:
1. A hybrid vehicle mode-switching control device for a hybrid vehicle that is equipped with an electric motor in addition to an engine as power sources, the engine is drive-coupled to vehicle wheels via a transmission, and the transmission and the vehicle wheels can be decoupled by a clutch; the hybrid vehicle mode-switching control device comprising: at least one controller programmed to select an electric operation mode in which operation is powered by the electric motor only by releasing the clutch and stopping the engine and to select a hybrid operation mode in which operation is powered by the electric motor and the engine by starting the engine and engaging the clutch, the at least one controller being further programmed to control an output of at least one of the electric motor and the engine to a value dependent on a vehicle running state while mode switching from the electric operation mode to the hybrid operation mode, and upon determining an actual transmission gear ratio of the transmission differs from a target transmission gear ratio corresponding to the vehicle running state, the at least one controller being further programmed to correct the output of the at least one of the electric motor and the engine to reduce a surplus or deficit of drive power caused by a transmission gear ratio deviation between the actual transmission gear ratio and the target transmission gear ratio.
