Hybrid vehicle, control device for hybrid vehicle, and control method for hybrid vehicle with throttle valve control according the temperature of the battery

A control device for a hybrid vehicle, the hybrid vehicle including an internal combustion engine, a rotary electric machine and an electrical storage device, the internal combustion engine including a variable valve actuating device and a throttle valve, the variable valve actuating device being configured to change an operation characteristic of an intake valve, the throttle valve being configured to adjust an amount of air that flows into a cylinder, the control device comprising:

• a controller configured to
• execute output control in which an opening degree of the throttle valve is controlled such that, when a temperature of the electrical storage device is lower than a predetermined temperature, an output of the internal combustion engine is reduced below a predetermined output, and
• control the variable valve actuating device such that at least one of a valve lift or valve operating angle of the intake valve at the time when the output control is executed is larger than the corresponding at least one of the valve lift or valve operating angle of the intake valve at the time when the output control is not executed.
