- the engine can be started by rotationally driving the engine with an electric motor.
- Patent Document 1 when the engine is started by the motor during motor traveling (EV traveling) using only the electric motor as a driving force source for traveling, the torque capacity of the connection / disconnection clutch is equal to the driving torque component (In other words, a technology that prevents a temporary shortage of driving torque during travel and shocks resulting therefrom by increasing the motor torque (as much as the motor torque that flows to the engine side via the connection / disconnection clutch as torque for rotationally driving the engine). has been proposed.
- the actual value of the torque capacity of the connecting / disconnecting clutch is estimated from, for example, the engagement pressure command value of the connecting / disconnecting clutch, but for the sake of control accuracy, there is a slight difference between the actual value of the torque capacity and the estimated value. There is a possibility of deviation.
- the present invention has been made against the background of the above circumstances, and an object of the present invention is to provide a control device for a hybrid vehicle that can achieve both suppression of deterioration of fuel consumption and suppression of shock when starting the engine. There is to do.

(B) When the gear stage when starting the engine uses the one-way clutch as an engaging element, the gear stage does not use the one-way clutch as an engaging element. Also, the increase in the output of the electric motor when starting the engine is increased.
- the one-way clutch is not used as an engaging element during traveling at a gear stage having the one-way clutch as an engaging element.
- the object is to reduce the area in which the motor travel is performed as compared with traveling in a gear stage.
- the motor can output during motor travel at a gear stage that uses the one-way clutch as an engagement element, compared to during motor travel at a gear stage that does not use the one-way clutch as an engagement element.
- the power that can be used for starting the engine is increased by the amount of power that can be used for driving the vehicle, among the power that is reduced. Accordingly, it is possible to appropriately increase the increase in the output of the electric motor at the time of starting the engine at the gear stage having the one-way clutch as an engagement element.
- a third aspect of the invention relates to the hybrid vehicle control device according to the first or second aspect of the invention, wherein the connection / disconnection when the engine is started in a gear stage having the one-way clutch as an engagement element. If the one-way clutch is disengaged when the clutch is engaged, the engagement pressure of the connecting / disconnecting clutch when the engine is started next time in the gear stage is made smaller than the previous one. In this way, when the engine is started at the gear stage having the one-way clutch as an engagement element, the increase in the motor torque is easily made larger than the actual value of the torque capacity of the connection / disconnection clutch, and the synchronous shock of the one-way clutch is increased.
