This paper develops a vehicle carried remote data acquisition terminal based on GPS/GPRS integrated DTU(data transfer unit) and CAN Bus data acquisition module, and built a parameter remote monitoring system of HEV with GPRS and Internet. By using PIC18F4580 with built in CAN control module and industrial DTU MD610G, we transmitted the parameter data and GPS information of the HEV(Hybrid Electric Vehicle) terminals to the remote data control center through GPRS(General Packet Radio Service) and INTERNET. Taking VC++ as the development tool, we programmed a monitoring software of data exchanging, data processing and monitoring. The software also has the function of CANoe data playbacking and strengthened the system versatility. Eventually, the parameter remote monitoring system of HEV is developed. The experiment results show that the system works well.
