The invention discloses a hydraulic hybrid power transmission system with a self-adaption switching function, and belongs to the field of power transmission. The hydraulic hybrid power transmission system comprises an engine, a high-pressure energy accumulator, a low-pressure energy accumulator, a constant-pressure variable pump, a hydraulic transformer, a fixed-displacement hydraulic motor and two hydraulic-control one-way valves. When a vehicle needs to switch between driving/braking conditions, after the control angle of the hydraulic transformer is changed, the two hydraulic-control one-way valves are controlled through the cross feedback of system pressure, so that the self-adaption switching between driving/braking conditions is realized; therefore, the control complexity and the control difficulty of the hydraulic hybrid power transmission system are reduced.
