摘要
由于汽车标定系统软件难以普遍适用于不同应用场景,按照国家标准,设计了一种基于CAN协议的动力转向系统方向盘角度标定诊断软件。根据通信协议类型配置初始参数,建立诊断设备与汽车ECU之间的数据通信连接,再对汽车ECU进行数据采样并对采样数据进行分析提取,建立标定模拟数据库,通过设计标定功能函数运行程序,最终实现诊断仪标定功能。经测试运行,显示该软件可以实现预期标定功能,降低标定工作的复杂程度。
It is difficult for automobile calibration system software to be universally applicable to different application scenarios.According to the national standard,a kind of steering wheel angle calibration and diagnosis software based on CAN protocol for power steering system was designed.The initial parameters were determined according to the communication protocol type,and the data communication connection between the diagnostic instrument and the automobile ECU was established.Then,the data of ECU was sampled and analyzed,and the calibration simulation database was obtained.Finally,the program was designed to realize the calibration function of the diagnosis instrument.The test operation shows that the software can achieve the expected calibration function and can reduce the complexity of the calibration work.
