Abstract: A control device of a hybrid vehicle including an engine, motor that receives power from the engine via an engine connecting and disconnecting device, and automatic transmission, starts the engine in a first starting method in which the engine performs ignition and rotates by itself after the engine speed is increased to be equal to or higher than a predetermined rotational speed through slipping engagement of the engine connecting and disconnecting device, or a second starting method in which the engine performs ignition and rotates by itself from a stage before the engine speed reaches the predetermined rotational speed, and controls the automatic transmission to permit a lower gear position to be established according to shift conditions when the engine is started in the second starting method during a downshift of the automatic transmission, as compared with when the engine is started in the first starting method during the downshift.

Abstract: A controller for a hybrid vehicle is configured to execute a shifting assist process of increasing torque of a motor when performing power-on downshift of an automatic transmission and an upper limit assist torque setting process of setting an upper limit assist torque that is an upper limit value of a travel assist torque to be a smaller value when a maximum step number of the power-on downshift is large than when the maximum step number is small.

Abstract: A control device executes, when a jump-down shifting is executed, shifting control in which, after engaging elements establishing a pre-shifting gear position are released, an intermediate gear position that is a gear position between the pre-shifting gear position and a post-shifting gear position is established, and after the intermediate gear position is established, the post-shifting gear position is established. When an engaging element able to reduce a rotation speed difference between two rotating bodies connected by engaging elements establishing the intermediate gear position is regarded as a speed difference reducing element, the control device executes a pre-engaging process for generating a torque capacity in the speed difference reducing element while the shifting control is being executed and before establishing the intermediate gear position.
