摘要
汽车电控制单元的开发中,一项重要的工作是对控制规律参数进行调解,也就是所谓“控制单元的标定”。文章介绍了一个用于机械式自动变速器(AutomatedManualTransmission,AMT)控制单元的标定系统,它采用控制器局域网(ControllerAreaNetwork,CAN)标定协议CCP(CANCalibrationProtocol),通过CAN网络实现标定计算机与被标定的控制单元的通信,实现对控制单元数据的调节和数据的上传和下载。标定操作界面支持数据点、曲线和数据表的标定操作。直接对曲线的拖动功能,使修正脉谱图时更直观。通过实际AMT控制单元开发应用,验证了标定系统的性能。
In the development of automotive control unit,one of the key work is to adjust the control parameters,that is the so called ＂control system calibration＂.In the paper a calibration system is introduced that is used for developing of AMT（Automated Manual Transmission ）.It supports CCP（CAN Calibration protocol,CAN：Controller Area Network）,and the calibrated control unit and the calibrating computer are connected through CAN.With the CAN the data are up- loaded and down-loaded.The calibration interface supports editing of datum points,curve and table.The function of draging curve point make map calibration more straight.The functions of the system are tested in the application of a AMT control unit development.
