本文记录一下学习DTC测试的一些基础知识与canoe配置在这个过程中遇到的一些问题一、什么是IL有什么作用参考文档1.CAN Interaction Layer (谈谈我对交互层的理解)_蚂蚁小兵-CSDN博客_interaction layer2.总线仿真还可以这样玩_怿星科技的博客-CSDN博客3.CANoe DLL 导入与使用-CSDN博客1.IL的理解IL层在message发送到总线上之前默认情况下IL层的参数是在DBC文件中定义的。IL层定义message 和signal的行为方式比如什么时候发发送周期是多少。2.常见的函数1long ILControlInit () 初始化 IL 这个函数只能在 on preStart中使用 目的是阻止 IL自动启动 IL 是默认生效的 2long ILControlStart 和 ILControlStop 开始和停止IL层 开启时发送相关的报文 3long ILSetMsgEvent (dbMessage msg) 直接向总线上发送一帧报文 4long ILFaultInjectionDisableMsg (dbMsg msg)停止发送某一帧报文 5long ILFaultInjectionEnableMsg (dbMsg msg);恢复报文的发送 6long ILFaultInjectionSetMsgCycleTime (dbMsg msg, double value)更改报文的周期 7long ILFaultInjectionResetMsgCycleTime(dbMsg msg);恢复报文的周期 8long ILNodeControlStop(char aNodeName[])停止指定仿真节点的交互层节点所有报文停发 9long ILNodeControlStart(char aNodeName[]);重启指定仿真节点的交互层 10dword appILTxPending(long aId, dword aDlc, byte data[]); IL 准备往总线发送任意一帧报文之前每帧发送前都会进入这个回调。 可以直接修改data[]数组下发到总线的就是改后数据 回调内部禁止使用 setSignal 系列函数会反复触发 IL 发送逻辑造成无限循环、总线风暴。注只能在IL节点上调用测试工程才能调用上面这些函数才能正常的停发报文3. CANOEILNLVECTOR.DLL是 Vector CANoe 自带的 Interaction Layer Node Layer 库属于官方库。它的作用可以简单理解成给仿真节点提供“基于 DBC 的报文交互能力”依赖 CANoe 的 IL 机制按数据库做这些事按 DBC 的周期、初值、发送类型自动发报文支持 setSignal() 改信号后自动映射到对应报文支持 testEnableMsg() / testDisableMsg() 这类基于 IL 的停发/使能维护消息更新、信号打包等基础行为常见配合方式有两种纯 IL只改信号IL 自动发整帧IL CAPLIL 先正常发CAPL 再拦截或二次加工二、创建与配置工程1.创建两个can通道右键重命名2.在CAN2上添加节点配置为IL节点自动发送dbc里面的报文参考链接1CANoe DLL 导入与使用-CSDN博客1在对应的总线上添加dbc2右键选择节点3右键节点Configuration查看节点配置4右键节点- Open IL Configuration勾选需要发送发送的报文跟DTC相关的报文3. 创建测试环境详情可参考: 使用Canoe写CAPL自动化脚本_canoe自动化测试脚本-CSDN博客三、测试思路及代码1.故障类型报文丢失整个节点丢失CRC 错误Rolling Counter 错误信号失效/越界2.测试思路先清空 ECU 当前 DTC。通过停发报文、修改 CRC、固定 rolling counter、修改信号值等方式制造故障。用 UDS 0x19 周期性读 DTC。记录“首次读到当前故障”的时间判断是否落在规范时间窗口内。去掉故障。再周期性读 DTC判断是否在规定时间内从“当前故障”变成“历史故障”。3.测试代码简略不全DTC_test.can /*!Encoding:936*/ includes { #include ../Include/IniConfig.cin #include ../Include/UDS_DiagServices.cin #include ../Include/E2E for SDA-S.cin #include ../Include/Common.cin #include ../Include/ReportAndLog.cin } variables { dword Channel_CAN1 65537;

返回值 1仅激活CAPL脚本 2仅激活NodeLayer DLL信号层数据库节点仿真依赖它 3同时激活 CAPL NodeLayer如果该节点配置了诊断 ECU 仿真一并挂载到总线网络 把仿真节点Simulation Node 恢复到总线在线状态。 配套函数 canOffline() 是断连总线调用 canOnline() 后节点才能正常通过 output() 往总线发报文。 2.控制交互层周期报文的自动发送 long TestEnableMsg (dbMessage aMessage);//dbc报文名字 long TestEnableMsg (dword aMessageId);//can ID long TestDisableMsg (dbMessage aMessage); long TestDisableMsg (dword aMessageId);//can ID long TestSetMsgEvent (dbMessage aMessage); long TestSetMsgEvent (dword aMessageId);强制发一帧报文到总线上无论报文当前是禁用/启用 void setSignal(Signal aSignal, double aValue);设置信号的物理值五、遇到的问题1.报告里面一直有测试框架自动加进去的 Resume reason这些无关信息导致测试报告不简洁解决方法补充tse文件DTC_test.tse 本质上是 CANoe Test Setup 的“测试环境配置文件”主要描述这个测试模块叫什么绑定哪个 .vxt用哪个 CAPL 库报告怎么生成报告里显示哪些内容当前测试环境窗口布局和一些控制器状态 DTC产生与恢复
本文记录一下学习DTC测试的一些基础知识与canoe配置在这个过程中遇到的一些问题一、什么是IL有什么作用参考文档1.CAN Interaction Layer (谈谈我对交互层的理解)_蚂蚁小兵-CSDN博客_interaction layer2.总线仿真还可以这样玩_怿星科技的博客-CSDN博客3.CANoe DLL 导入与使用-CSDN博客1.IL的理解IL层在message发送到总线上之前默认情况下IL层的参数是在DBC文件中定义的。IL层定义message 和signal的行为方式比如什么时候发发送周期是多少。2.常见的函数1long ILControlInit () 初始化 IL 这个函数只能在 on preStart中使用 目的是阻止 IL自动启动 IL 是默认生效的 2long ILControlStart 和 ILControlStop 开始和停止IL层 开启时发送相关的报文 3long ILSetMsgEvent (dbMessage msg) 直接向总线上发送一帧报文 4long ILFaultInjectionDisableMsg (dbMsg msg)停止发送某一帧报文 5long ILFaultInjectionEnableMsg (dbMsg msg);恢复报文的发送 6long ILFaultInjectionSetMsgCycleTime (dbMsg msg, double value)更改报文的周期 7long ILFaultInjectionResetMsgCycleTime(dbMsg msg);恢复报文的周期 8long ILNodeControlStop(char aNodeName[])停止指定仿真节点的交互层节点所有报文停发 9long ILNodeControlStart(char aNodeName[]);重启指定仿真节点的交互层 10dword appILTxPending(long aId, dword aDlc, byte data[]); IL 准备往总线发送任意一帧报文之前每帧发送前都会进入这个回调。 可以直接修改data[]数组下发到总线的就是改后数据 回调内部禁止使用 setSignal 系列函数会反复触发 IL 发送逻辑造成无限循环、总线风暴。注只能在IL节点上调用测试工程才能调用上面这些函数才能正常的停发报文3. CANOEILNLVECTOR.DLL是 Vector CANoe 自带的 Interaction Layer Node Layer 库属于官方库。它的作用可以简单理解成给仿真节点提供“基于 DBC 的报文交互能力”依赖 CANoe 的 IL 机制按数据库做这些事按 DBC 的周期、初值、发送类型自动发报文支持 setSignal() 改信号后自动映射到对应报文支持 testEnableMsg() / testDisableMsg() 这类基于 IL 的停发/使能维护消息更新、信号打包等基础行为常见配合方式有两种纯 IL只改信号IL 自动发整帧IL CAPLIL 先正常发CAPL 再拦截或二次加工二、创建与配置工程1.创建两个can通道右键重命名2.在CAN2上添加节点配置为IL节点自动发送dbc里面的报文参考链接1CANoe DLL 导入与使用-CSDN博客1在对应的总线上添加dbc2右键选择节点3右键节点Configuration查看节点配置4右键节点- Open IL Configuration勾选需要发送发送的报文跟DTC相关的报文3. 创建测试环境详情可参考: 使用Canoe写CAPL自动化脚本_canoe自动化测试脚本-CSDN博客三、测试思路及代码1.故障类型报文丢失整个节点丢失CRC 错误Rolling Counter 错误信号失效/越界2.测试思路先清空 ECU 当前 DTC。通过停发报文、修改 CRC、固定 rolling counter、修改信号值等方式制造故障。用 UDS 0x19 周期性读 DTC。记录“首次读到当前故障”的时间判断是否落在规范时间窗口内。去掉故障。再周期性读 DTC判断是否在规定时间内从“当前故障”变成“历史故障”。3.测试代码简略不全DTC_test.can /*!Encoding:936*/ includes { #include ../Include/IniConfig.cin #include ../Include/UDS_DiagServices.cin #include ../Include/E2E for SDA-S.cin #include ../Include/Common.cin #include ../Include/ReportAndLog.cin } variables { dword Channel_CAN1 65537;

返回值 1仅激活CAPL脚本 2仅激活NodeLayer DLL信号层数据库节点仿真依赖它 3同时激活 CAPL NodeLayer如果该节点配置了诊断 ECU 仿真一并挂载到总线网络 把仿真节点Simulation Node 恢复到总线在线状态。 配套函数 canOffline() 是断连总线调用 canOnline() 后节点才能正常通过 output() 往总线发报文。 2.控制交互层周期报文的自动发送 long TestEnableMsg (dbMessage aMessage);//dbc报文名字 long TestEnableMsg (dword aMessageId);//can ID long TestDisableMsg (dbMessage aMessage);
