SUPPORT SYSTEM

A display control device for a support system includes a number-of-charging-lights determination unit for determining the number of charging lights, which corresponds to state-of-charge which ranges from maximum state-of-charge of a driving battery to a charge threshold and is assigned to a plurality of segments; a number-of-output-lights determination unit for determining the number of output lights, which corresponds to a difference, where a requested output ranging from an output that can be output to an output threshold is assigned to the plurality of segments; and a number-of-lights instruction unit for instructing a display device to light up the least number of segments of the number of charging lights or the number of output lights, when an EV priority mode is selected.
