A regenerative braking energy recovery system of a hydraulically-driven automobile is characterized in that each wheel half axle of the automobile is provided with a secondary element pump/motor, andthe wheel half axles are connected with the secondary element pumps/motors through electromagnetic clutches; a torque sensor and a rotating speed sensor are installed on each wheel half axle; each secondary element pump/motor is connected with a hydraulic oil cylinder; each secondary element pump/motor is connected with a high-pressure energy accumulator through a second two-position two-way electromagnetic reversing valve; a pilot pressure control valve and a pressure sensor are connected with the oil outlet of each high-pressure energy accumulator, and each high-pressure energy accumulator is controlled to be connected and disconnected through the pilot pressure control valve; the secondary element pump/motor is connected with a hydraulic master pump through a first two-position two-wayelectromagnetic reversing valve; the hydraulic master pump is connected with the hydraulic oil cylinders through hydraulic pipelines; and the hydraulic master cylinder is sequentially connected with areduction gearbox, a clutch and an engine. All components are connected with a controller. The hydraulic regenerative braking recovery system is applied to an internal combustion engine passenger vehicle, so the complexity of the transmission structure of a traditional internal combustion locomotive is reduced.
