1. A filter regeneration control device for a particulate filter provided in an exhaust passage of a vehicle equipped with a traveling power source including an engine with a plurality of cylinders, the filter regeneration control device comprising:
a fuel supply controller configured to control fuel supply to the plurality of cylinders; and
a rotation speed controller configured to control a rotation speed of the engine,
wherein, when a forced regeneration request for burning particulate matter collected in the filter is received while the vehicle is stopped and the engine is in an idle operation, the filter regeneration control device executes a filter regeneration control in which:
the fuel supply controller stops the fuel supply to at least one cylinder of the plurality of cylinders while supplying fuel to remaining cylinders of the plurality of cylinders, and
the rotation speed controller increases the rotation speed of the engine so as to be greater than a normal idle rotation speed of the idle operation.
