Hybrid vehicle powertrain test system capable of simulating working condition and inertia

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...

Problems solved by technology

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 problems, etc. have great limitations, the improvement of research and development quality is also limited, and the working conditions and safety of test personnel are also difficult to guarantee.

In addition, the improvement effect of the hybrid powertrain or a certain component needs to be assessed on the vehicle platform and the entire system, which also limits the development and improvement

The adoption of such research and development test methods greatly prolongs the research and development cycle, greatly affects the improvement of our research and development work level, and creates huge technical obstacles in the development and industrialization of hybrid vehicles.
