A hydraulic active suspension flow control system, comprising a hydraulic oil tank (1), a variable displacement pump (2) having an oil suction port communicated with the hydraulic oil tank (1), and a one-way valve (4), a servo valve (8) and a suspension cylinder (7) controlled by the servo valve (8) which are sequentially connected to an oil discharge port of the variable displacement pump (2). The variable displacement pump (2) is connected to an engine (9) by means of a clutch (12). An energy accumulator (6) is communicated between the servo valve (8) and the one-way valve (4). The hydraulic active suspension flow control system further comprises an oil pressure sensor (5) mounted at an outlet of the energy accumulator (6), an engine rotational speed sensor (10), a vehicle speed sensor (11), and a flow controller (13) for controlling the displacement of the variable displacement pump (2). An overflow valve (3) communicated in parallel with the one-way valve (4) is further provided at the oil discharge port of the variable displacement pump (2).
