Zusammenfassung:	A hybrid vehicle has a first running mode with an engine stopped and a second running mode with the engine operating. An ECU monitors information related to the frequency of intermittent startup of the engine in response to the startup and stoppage of the engine during vehicle running. The ECU executes running control such that startup of the engine is suppressed during the first running mode when in an operation pattern in which the frequency of intermittent startup is high. Accordingly, discomfort to the driver and degradation in fuel efficiency caused by repeating stoppage and startup of the engine frequently in a short period of time can be prevented.
