The invention discloses a slow active hydraulic suspension system driven by an exhaust gas turbine and a control method. The slow active hydraulic suspension system comprises an air spring, a hydraulic system, an exhaust gas turbine system and an ECU. The air spring is fixed between a vehicle body and the hydraulic cylinder, the exhaust gas turbine system is connected with the hydraulic system, and the ECU is in communication control connection with the hydraulic system and the exhaust gas turbine system at the same time. The hydraulic system comprises a hydraulic cylinder, a two-way adjustable damping valve, an overflow valve, an upper energy accumulator, a lower energy accumulator and a one-way hydraulic pump; the waste gas turbine system comprises a turbine, a friction clutch and an engine exhaust pipe, the turbine is arranged in the engine exhaust pipe, an output shaft of the turbine is connected with a driving part of the friction clutch, a driven part of the friction clutch is connected with an input shaft of the one-way hydraulic pump, and the one-way hydraulic pump is communicated with the two-position four-way reversing valve and the hydraulic system to form a loop. Engine waste gas is used for driving the turbine to provide power for the one-way hydraulic pump, energy is saved, the endurance mileage of the vehicle is shortened, and energy of the engine waste gas is reduced.
