Abstract
An ECU (Electronic Control Unit) that controls a plug-in hybrid vehicle starts an engine when a required power as a value obtained by subtracting a required discharge amount from a drive power is larger than a threshold during intermittent control in a CD (Charge Depletion) mode, and stops the engine when the required power is smaller than a threshold. When intermittent control is being performed in the CD mode, the ECU limits the required discharge amount Pout to a relatively small value in a range where an engine coolant temperature is low, and sets the required discharge amount relatively large instead of imposing a limit thereon in a range where the engine coolant temperature is high.
