CANoe软件在AMT发动机扭矩试验中的应用

The Application of CANoe software in AMT Engine Torque Test

AMT发动机标定时,需要测试扭矩响应曲线,提出一种应用CANoe软件在线半物理仿真的方法来获取所需数据。首先通过对CANoe软件进行系统配置、建立数据库及创建网络节点并对节点进行CAPL语言编程等一系列工作,实现CAN网络节点的半物理仿真。其次通过CANcardXL接口卡及CANcab 251opto连接线缆的连接将仿真节点挂载到CAN网络,与CAN网络中的实际ECU节点进行通讯来测试ECU的扭矩响应时间参数。经分析表明所得到的试验结果满足试验要求。

When AMT engine calibrates, a new method of CANoe software utilized in on-line Semi-physical simulation is raised in this paper to obtain the information because of the torque corresponding test First, the function of CAN Semi-physical simulation of Network Node will be fulfilled through the configuration of software, foundation of data base, establishment of the Network Node and the programming with CAPL. Second, the simulation nodes will be connected with the CAN network through CANcardXLInterface Card and CANcab 25 lopto Cable, communicating with the actual ECU network node in CAN network so as to test the torque corresponding time parameters. All the testing results coincide well with the testing demands.
