Performance simulation system for extended-range electric vehicle

Abstract

The invention discloses a performance simulation system for an extended-range electric vehicle. A driver module is connected with a control module through a signal line, an engine module is in signalconnection with a generator module, the generator module is in signal connection with a battery module, the battery module is further in signal connection with an accessory module, the motor module isfurther in signal connection with the speed reducer module, the speed reducer module is further in signal connection with a whole vehicle module, the whole vehicle module is further in signal connection with the control module, and the control module is in signal connection with the engine module, the generator module, the battery module, the accessory module, the motor module and the speed reducer module. According to the invention, a model and parameters can be flexibly and freely modified, an operator can conveniently understand the simulation calculation principle and master the operationmethod, the electric consumption rate of an electric drive part of the extended-range electric vehicle can be simulated, meanwhile, the fuel consumption rate of a range extender part can also be simulated, the dynamic property of the whole vehicle can also be simulated, and the output forms are flexible and diverse.

Description

technical field [0001] The invention relates to the technical field of vehicle performance simulation, in particular to a performance simulation system for an extended-range electric vehicle. Background technique [0002] Under the double pressure of environment and energy, electric vehicles are developing rapidly. However, factors such as limited mileage and high battery costs still restrict the further promotion of electric vehicles. The extended-range electric vehicle is a generator system added to the pure electric vehicle, which can effectively solve the current technical shortcomings of pure electric vehicles and is an important direction for the development of new energy vehicles. Performance simulation analysis is a very important link in the development process of automobile projects. Through simulation analysis, it supports powertrain selection, and can preliminarily evaluate whether the power economy meets the expected indicators. At the same time, through simu...

Problems solved by technology

However, Cruise is a non-open source software, and its calculation methods are all encapsulated in the software. It is impossible to view and modify the calculation methods. The flexibility is poor, and it is not convenient for the simulation and simulation of the control strategy of the extended-range electric vehicle.

When performing detailed control strategy simulation, Cruise needs to use Matlab software for co-simulation. The matching and docking of the two software models is not easy to achieve and is prone to errors
