The invention discloses a novel electrical-hydraulic hybrid power transmission system for a saloon car. The system comprises an electric driving system, a coupling mechanism and a hydraulic driving system, and the hydraulic driving system is connected with the coupling mechanism through a clutch. According to the novel electrical-hydraulic hybrid power transmission system applied to the saloon car, the hydraulic driving system composed of a hydraulic pump/motor, a high-lower pressure energy accumulator, a hydraulic valve component and a hydraulic controller on the basis of an original pure electric automobile transmission system, braking energy can be recycled and utilized more effectively, influences, produced on the cycle life of an accumulator, of large current charging and discharging are avoided, and electrical losses of an electric motor and abrasion of a friction plate of a brake are reduced.
