Hybrid vehicle

A hybrid vehicle comprising:

• an internal combustion engine having a variable valve actuation device for varying an actuation characteristic of an intake valve;
• a chargeable power storage device;
• a first rotating electric machine receiving electric power supplied from said power storage device to generate driving force to cause the hybrid vehicle to travel;
• and
• a control device operative in response to a vehicular required power that the vehicle is required to output being smaller than a threshold value for stopping said internal combustion engine and allowing a driving force of said first rotating electric machine to be used to cause the vehicle to travel, and operative in response to said vehicular required power exceeding said threshold value for starting said internal combustion engine and allowing a driving force of said internal combustion engine and the driving force of said first rotating electric machine to be both used to cause the vehicle to travel,
• said variable valve actuation device being configured to select a first state and a second state, in the second state at least one of an amount of lifting said intake valve and a working angle on said intake valve is larger than in said first state,
• said control device performing a process to increase said threshold value to be higher when said first state is selected than when said second state is selected.
