Abstract

The 21st century, the development of the car has full access to the electronic information era, the development of automotive electronics determines the status of the countries in the world automotive industry, for electric vehicle research has become the focus of the industrial countries, how to achieve optimal control of the electric car almost become a hot issue. This article first introduces the research background and significance of electric vehicles, the development of electric vehicles at home and abroad, the prospects for development, and describes the data analysis techniques, which put forward the research content of this article - This article is focused on the four-wheel-drive electric needs of automotive control systems, the development of the experimental data analysis software of the host computer. Then, according to the functional requirements of the system to determine the overall scheme of the system, and the system is divided into three modules: the experiment data entry and display module, the experiments data processing module, controller parameter tuning and simulation modules. And according to the system needs to determine MATLAB to achieve the background as system development platform of VC data processing, give full play to the powerful advantages of VC and MATLAB mixed programming. Detailed experimental data entry and display module the control theoretical basis, based on the above four drive electric vehicles, describes the steps of the four-wheel-drive electric vehicle data analysis system programming in VC environment, including to use CSerialPortEx serial port class implements serial communication established through the Access database using ODBC technology to achieve a four-wheel-drive electric vehicle display of historical data, to use MSChart achieve speed real-time dynamic display. Electric vehicle structure - mechanical transmission means and with the motor output shaft in the experimental data processing module, according to a kinematic contact reducer and the reduction gear of the drive shaft and the main gearbox or transmission and other mechanical devices, analysis of the dynamics of the electric vehicle equation, with detailed descriptions of the experimental data processing module of the four-wheel-drive electric vehicle design methods and procedures, as well as the VC and MATLAB mixed programming system. Controller parameter tuning and simulation modules, based on first-order control system FOLPD model, according to the data acquisition system models using the least squares fit, and came to the theory of the system transfer function. Then the PID controller toolbox written in with Xue Dingyu teacher to determine the four-wheel-drive electric vehicle control program to identify the different control parameters and draw simulation curve controller simulation parameters tuning the last details and Simulation Module design steps and design methods.
