Abstract:
A vehicle control device includes a power storage device, a drive device, a system main relay attached to a power line, and a charge circuit connected to the power line on a side of the drive device from the system main relay. The vehicle control device turns off the system main relay in a power shortage of the power storage device, and store a power shortage state of the power storage device to prohibit reactivation of the system. The vehicle control device, when charging of the power storage device using the charge circuit is requested, determines whether the power shortage state of the power storage device is stored, and when the power shortage state of the power storage device is stored, releases prohibition of system reactivation when an output limit of the power storage device reaches predetermined electric power or more due to charging.
