Study of Monitor and Control for Motor Propulsion System on Hybrid Electric Vehicle

摘要:

通过串口通信实现混合动力汽车电机驱动系统的电池组电压、电流和加速踏板位置等信号的实时采集、处理和显示,并对驱动系统进行诊断；采用PWM(脉宽调制)技术控制电动机速度；上位机(PC机) 程序采用 Delphi高级语言编写,下位机(单片机)程序采用C语言编写。通过对系统调试与模拟仿真,表明所设计的系统有效和可行。

Abstract:

The real-time voltage and current signal of battery and the position signal of accelerator pedal were gathered, processed and displayed for motor propulsion system on hybrid electric vehicle by serial communication., and the propulsion system was diagnosised. Motor speed was controlled by PWM technique. The PC program was compiled by using Delphi language. and the SCM program was compiled by C language. System was tested and simulated, the result indicated that the system was effective and viable.
