To provide a hybrid vehicle that can drive an engine so as to output power in a range where the engine is efficiently driven, and can charge a battery with surplus power as electricity, and its control method.
When a condition that a vehicle speed V is not higher than a threshold Vre and a condition that a road gradient θ is not smaller than a threshold θref are satisfied in case that a motor is brought into a high-temperature state during motor traveling, the engine 22 is started when the engine is stopped (S116), a battery charging request Pb* is reset so that power not smaller than the lowest limit of the range where the engine is efficiently driven is outputted from the engine, requested power Pe* is reset by using the charging request Pb* (S118, S120), and the engine and the motor are controlled by using the requested power Pe* (S122 to S128).
