GPF regeneration control system and control method

The invention discloses a GPF regeneration control system and method. The GPF regeneration control system comprises a control unit, an oxygen tank, an oxygen guide pump, an oxygen guide pipe and an electric control valve. The first end of the electric control valve is connected with an inlet of the GPF, and the second end is connected with the first end of the oxygen guide pump through an oxygen guide pipe; the second end of the oxygen guide pump is connected with an oxygen tank through an oxygen guide pipe; oxygen is stored in the oxygen tank; the control unit is electrically connected with the oxygen guide pump and the control end of the electric control valve respectively; and the control unit is used for controlling the electric control valve and the oxygen guide pump to be opened when determining that the current carbon loading capacity of the GPF reaches a regeneration threshold value and meets a regeneration condition, so that oxygen in the oxygen tank enters the GPF through the electric control valve,
