Upon a system startup, a hybrid vehicle 20 determines whether a catalyst warm up operation of an engine 22 is to be executed or not based on a catalyst bed temperature Tcat of an exhaust gas purifying catalyst 141 and a state of charge SOC of a battery 50 (S110, S140) and determines whether a forced charging of the battery 50 with an idling of the engine 22 is to be executed or not based on the catalyst bed temperature Tcat, the state of charge SOC and an estimated intake air amount GAidl upon the idling of the engine 22 when the catalyst warm up operation is not to be executed, then controls the engine 22, motors MG1 and MG2 in accordance with determination results (S130, S210).
