The invention discloses a hybrid power assembly performance matching test bench which comprises an engine, a clutch, a speed changer, an engine controller ECU, a power generating / motor-driven integrated motor ISG, a motor controller IPU, a power battery pack, a battery management system ECU, a vehicle controller HCU, a DC converter DC / DC, a shift mechanism, a clutch pedal, a brake pedal, an accelerator pedal, two dynamometers, a bench control system and a rapid control prototype dSPACE. The test bench has the advantages that the entire vehicle state is simulated on an engine test bench, the main parts of the hybrid power system, the power battery pack, the BCU, the HCU, the IPU and the DC / DC are arranged by simulating the entire vehicle state, the sturcture is compact, the testing programis simple, the performance matching of the hybrid power assembly can be easily realized on the test bench, and NEDC and other condition tests can be conducted by simulating the entire vehicle.
