Simulation experiment method of parallel hybrid hybrid electric vehicle in urban cycle condition

Abstract

The invention relates to the technical field of oil-electric hybrid power and discloses a simulation experiment method and experiment device for an urban cycle condition of a parallel oil-electric hybrid electric vehicle. A motor is controlled by an experiment table to simulate the vehicle speed change of the parallel oil-electric hybrid electric vehicle in the urban cycle condition. Physical elements truly reflect the working states of an electric power module and a gearbox of the parallel oil-electricity hybrid electric vehicle. An upper computer simulates the working state of an automobileengine according to the real-time working state of the electric power module, and then the working state of the parallel type oil-electricity hybrid electric vehicle under the urban cycle working condition is obtained. A test bench comprises a battery, an electric hybrid power gearbox controller, an electric hybrid power gearbox and a dynamometer motor.

Description

technical field [0001] The invention relates to the technical field of oil-electric hybrid power, in particular to a simulation experiment method and a test device for urban cycle working conditions of a parallel oil-electric hybrid vehicle. Background technique [0002] Cherishing the dwindling oil resources and protecting the living environment of human beings are two major issues that human society needs to solve urgently, which has accelerated the development of hybrid electric vehicles and electric vehicles. Compared with traditional fuel vehicles, pure electric vehicles are clean, quiet, and efficient. However, due to the limitation of battery technology, it will take a long time for pure electric vehicles to market. Therefore, many automobile manufacturers around the world are focusing on the research and development of hybrid electric vehicles. The advantages of high-efficiency and low-emission vehicles, and the strong power and long mileage of traditional fuel vehi...

Problems solved by technology

[0003] A gasoline-electric hybrid vehicle is a complex collection of machinery and electrical appliances. In the early stage of vehicle development, if a large number of real vehicle tests are carried out directly by building a real vehicle, it will consume a lot of manpower, material resources and financial resources, and it will also make the design and development process difficult. The cycle is extended; it is difficult to fully reflect the characteristics of the system components by using computer simulation, and the result is quite different from the actual situation.
