The present invention provides a driving system and a vehicle driving method wherein a power storage unit that has a power storage function and that supplies power to an onboard control device can be used as a driving power supply for a vehicle. In the electric railway vehicle driving system, when the vehicle travels in a battery travel mode, the supply of power from a power collector is cut off by a first switch and the supply of power from a battery to a traction inverter 12 is enabled by a second switch, such that when a vehicle travel command is received in the battery travel mode, the current flowing to the traction inverter is cut off by a filter charging circuit selector unit and the power supplied from the battery is stored in a filter capacitor of the traction inverter, and when a command for moving the vehicle is received in the battery travel mode operating state, an electric motor is driven by the power supplied from the battery.
