摘要
基于CAN总线的电控发动机标定系统包括电控单元、通信模块和标定平台软件三个部分。电控单元的CPU采用32位单片机PowerPC 563,内部采用CAN总线通信。自行设计的通信模块实现了CAN协议与USB协议的转换,完成ECU与PC机之间的数据传递。用Visual C++6.0设计的标定软件平台,界面清晰简洁,操作方便。该系统已经应用到一种高压共轨柴油机燃油喷射系统的开发,成功实现了数据通信、参数显示、MAP生成、文档管理等功能,加快了开发进程。
In this paper, a design of the CAN Bus based calibration system for electronically controlled engines was presented. The system consisted of an electronic control unit （ECU）, a communication module and a calibration software platform. A 32-bit power PC 563 was used as a CPU, and CAN bus was used as a communication bus in the ECU. The communication module was able to perform data conversion between the CAN and USB protocol, and achieve data transmission between PC and ECU. The calibration platform was designed with the Visual C＋＋6.0. The user-interface was clear, simple and easily manipulative. The system was applied in the development of a high pressure common rail diesel engine system, achieving data transmission, parameter display, MAP generation, document operation, and so on, which accelerated the development process.
