The present invention ensures an engine start-up by a starter at the time of ignition ON, and suppress progress of deterioration of a capacitor. A control system for a plug-in hybrid vehicle has a drive system having a starter motor (1), a transverse engine (2), and a motor/generator (4), and also has a power supply system having a high voltage battery (21); a capacitor (23); and a hybrid control module (81) that controls charge and discharge of the capacitor (23). In the control system for an FF plug-in hybrid vehicle in which external charging of the high voltage battery (21) is available, the hybrid control module (81) starts the starter, performs a mode selection control and a charge/discharge control, maintains the capacitor voltage equal to or higher than a voltage (a) that allows the starter to start-up when a CD mode is selected at the time of ignition ON, and maintains a capacitor voltage equal to or less than a voltage (b) at which deterioration does not proceed at the time of ignition ON with the CS being selected. |
