Embodiment Construction
[0011] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0012] see figure 1 , the hybrid powertrain is formed by connecting the engine 9, the integrated power generation / electric motor ISG 8, the clutch 6 and the transmission 5 in the following form: the ISG 8 of the power generation / electric integrated motor includes two parts, the stator and the rotor, and the stator is installed on the engine with bolts 9 rear end face, the rotor is installed on the rear end face of the crankshaft of the engine 9 with bolts, and rotates together with the crankshaft; the friction plate of the clutch 6 is closely attached to the surface of the flywheel fixed on the rotor; the transmission 5 is connected with the clutch 6 through a spline shaft. The hybrid powertrain is respectively connected to the two first and second dynamometers 1 and 3 through the first and second vehicle axle shafts 4 and 7 connecte...

Abstract
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.
Description
technical field [0001] The invention belongs to the technical field of hybrid powertrain bench tests, and in particular relates to a performance matching test bench of a hybrid powertrain system. Background technique [0002] Hybrid electric vehicles have two power sources, gasoline engine and electric motor. The hybrid power system combines the advantages of the two power sources. It is a new type of vehicle energy-saving and environmental protection technology, and has been widely concerned and researched worldwide. As a new type of powertrain technology, the hybrid powertrain system, which uses power generation / electric integration ISG motor, transmission, and HEV system as important components, currently lacks a corresponding performance matching platform for simulating the vehicle state. The assembly system is matched and evaluated online, and based on the needs of hybrid system development, a hybrid powertrain performance matching test bench is designed. Contents of ...
