Hybrid vehicle and control method of same

A control method of a hybrid vehicle including an internal combustion engine, a motor which can output power to a driving shaft coupled with an axle, and an electric power storage device which can store electric power obtained by converting at least part of power from the internal combustion engine to electric power and which can supply the electric power to the motor, comprising the steps of:

• setting a required driving force required for running according to an operation of a driver;
• in response to the elapse of a predetermined time period after an instruction for starting the vehicle is given, starting the internal combustion engine if the required driving force is equal to or smaller than a predetermined driving force and the vehicle can travel using only the motor;
• detecting a temperature of coolant for the internal combustion engine;
• setting a delay time by which start of the internal combustion engine is delayed based on the detected temperature;
• starting the internal combustion engine based on the set delay time;
• and
• wherein the delay time is set to be shorter as the detected temperature is lower.
