Whole vehicle model system for whole vehicle controller of new energy vehicle

Abstract

The invention belongs to the field of electric vehicle, and especially relates to a whole vehicle model system for a whole vehicle controller of a new energy vehicle. The whole vehicle model system ischaracterized by comprising a driver module, a whole vehicle controller module, a motor module, a transmission module, a main reducer module, a vehicle wheel module, a vehicle speed module and a battery module; wherein the driver module is connected with an input end of the whole vehicle controller module, an output end of the whole vehicle controller module is connected with an input end of themotor module, an output end of the motor module is connected with an input end of the transmission module and an input end of the battery module, an output end of the transmission module is connectedwith an input end of the main reducer module, an output end of the main reducer module is connected with an input end of the vehicle wheel module, and an output end of the vehicle wheel module is connected with an input end of the vehicle speed module. The whole vehicle model system of the invention has the beneficial effects that: the number of real vehicle tests is reduced, test safety is improved, test repeatability is improved, and whole vehicle development period is shortened.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a vehicle model system for a vehicle controller of a new energy vehicle. Background technique [0002] New energy vehicles have significant advantages such as low noise, zero emission, high efficiency, energy saving and energy diversification. In the development of new energy vehicle technology, the research of each controller has very important strategic significance. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following shortcomings and deficiencies in the existing development research: [0004] In the process of invention, if a real controller and external environment are used for development and testing, it will consume a lot of manpower, material resources and financial resources, and the development cycle is long, the repeatability is poor, and the test conditions are more restricted. [0005] In o...

AI Technical Summary

Problems solved by technology

However, digital simulation is limited by modeling technology, and the simulation process is affected by the complexity of the model and the accuracy of parameters. The accuracy and reliability of simulation results cannot be guaranteed to a certain extent.

In addition, all-digital off-line simulation cannot evaluate real-time parameters such as model parameters, interfaces, and communications, and cannot be used to troubleshoot controller real-time software errors. The rapidity and real-time performance of the simulation are poor, and it cannot truly reflect the real-time characteristics of the system.
