Simulink-based motor controller software generation method for electric vehicle

Abstract

An embodiment of the invention provides a Simulink-based motor control software generation method for an electric vehicle. The method comprises the steps of establishing a simulation environment of a motor control model of the electric vehicle in a Simulink environment, and obtaining a Simulink-based control algorithm model subjected to simulation testing and an automatically generated software program; performing development to obtain a boot program, a program link software program and an underlying software program; in a compilation environment, combining a Simulink-based control algorithm software program, the program link software program and the underlying software program, and performing automatic compilation and link processing to obtain a binary executable file; and programming the binary executable file into a motor controller of the electric vehicle. Simulink-based motor control software obtained by implementing the method has the characteristics of hierarchicalization, modularization, expandability, reusability and the like, and the software development efficiency is improved.

Description

technical field [0001] The invention belongs to the field of electric vehicles, in particular to a Simulink-based method for generating software for an electric vehicle motor controller. Background technique [0002] With the progress of society and the development of science and technology, environmental and energy issues have become increasingly prominent. Therefore, the voice of developing and popularizing new energy vehicles such as electric vehicles is increasing day by day, and now electric vehicles (Electric Vehicle, EV), plug-in hybrid electric vehicles (Plug-in hybrid electric vehicle, PHEV) and extended-range electric vehicles (Extended range) are developed. -Range Electric Vehicle, EREV) and other types, mass production and sales of domestic and foreign electric vehicles have also begun. Electric vehicle motor controller is a key component, and its development process is bound to be different from traditional industrial motor controllers, but similar to the devel...
