Example Embodiment

[0015] Such as figure 1 As shown, the bench control and measurement center manager is a comprehensive system to complete the hybrid powertrain bench test. The main components include: operation console, bench control and measurement center manager, test mode control system, dynamic simulation system, Driving function controller, dynamometer and dynamometer controller, data acquisition system, test condition control system, etc.

[0016] The bench control and measurement center manager can perform automatic and manual operations on the bench. The system uses CAN bus to connect all devices, it collects all data and controls all devices.

[0017] The user computer is connected between the bench control and measurement center manager and the vehicle controller HCU of the tested vehicle, which is used to compare and analyze the related data of the bench and the related data of the vehicle HCU in real time, and it is also convenient to compare different HCUs. After “translation” of the...

Abstract

The invention discloses a hybrid vehicle powertrain test system capable of simulating working condition and inertia, which comprises an operating console, a bench control and measuring centre manger, a test mode controlling system unit, a dynamic simulating system unit, a driving function controller unit, a dynamometer, a dynamometer controller unit, a data acquisition system unit and a test condition controlling system unit. The system can be used in the hybrid vehicle powertrain performance development tests; the bench test can replace most of the road tests and the vehicle rotating hub tests in the process of developing the products; meanwhile, assembly parts of the powertrain can be combined flexibly to form different coupling modes of motors and engines to carry out the development and research in the early stage of the development of the hybrid vehicle powertrain; compared with traditional research and development testing means, the test system can greatly improve the hybrid vehicle powertrain and the research and development test level of the key technologies thereof and greatly shorten the research and development period of the powertrain and the relative parts.

Description

technical field [0001] The invention belongs to a vehicle powertrain test device, in particular to a hybrid electric vehicle powertrain test system Background technique [0002] A large number of experiments are required during the development of hybrid electric vehicles. At present, due to the limited conditions, it is often only possible to carry out the single-item assembly partial test mainly in the steady state test indoors. Although the traditional engine dynamic test bench has become more and more popular, it cannot complete the special test of the hybrid vehicle powertrain ( Such as energy feedback, etc.). A large number of tests of hybrid power and its management system are still completed by vehicle road tests. In this way, it is difficult to accurately reproduce the performance of a certain working condition and accurately and completely test the relevant parameters of the system. Coupled with the differences in weather and handling, the handling of road site p...
