摘要

隨著汽車保有量的不斷增加，環(huán)境污染和石油資源匱乏日益顯著，電動(dòng)汽車因其具有綠色環(huán)保和能源利用效率高等優(yōu)點(diǎn)，引起世界各國(guó)的廣泛關(guān)注。電力驅(qū)動(dòng)技術(shù)是制約電動(dòng)汽車發(fā)展的三大關(guān)鍵技術(shù)之一，因而研究電動(dòng)汽車驅(qū)動(dòng)控制系統(tǒng)具有重要意義。

Abstract

Along with the continuously increase of the automobile retention, the pollution of the environment and the shortage of petroleum resources were increasingly serious. Because of green environment protection and efficiently utilize energy, the electric vehicle (EV) was pain more attention by all over the world. Electric power is drive technique was one of EV, so the studying of the motor drive control system of EV has important significance.
This paper proposed the design of electric vehicle drive system is based on CAN-bus, through analyzing the performance requirement of the motor drive system applied to the EV, the design of the motor drive system is represented. For meeting the requirement of the high speed 、stabilization、real-time for motor drive system applied to the EV and through the analysis of EV is motor and control techniques ，We selected a permanent magnet DC motor as the electrical motor drive system .based on this, through the analysis of permanence magnet DC motor work characteristic and through the comparison of motor drive control method, the motor-driven control system was controlled by PWM through the CAN-bus.
The design of the software and hardware on the CAN-bus, the design of motor drive controller was studied by this paper, the design of hardware mainly contained: the total design project of hardware based on the LPC2119, the design of main control loop, motor current feedback circuit. The design of software include：On the CAN-bus, LPC2119 controller nodes initialization, CAN bus sent subroutine, CAN bus routines and receive CAN bus Exceptions interrupt procedures.
