关键参数说明表

参数名称示例值工程配置要点请求间隔150ms需小于ECU复位执行时间响应超时300ms覆盖ECU最大响应时间NRC 0x78请求未响应ISO 14229-1标准定义复位子功能0x01OEM定义的硬件复位类型

响应状态矩阵

请求序号预期状态失败场景示例1肯定响应(0x51)ECU未执行复位2NRC=0x78返回其他NRC或超时3NRC=0x78错误响应或系统崩溃

工业级增强功能

复位状态跟踪

// 通过系统变量监控实际复位动作 on sysvar ECU::PowerStatus { if(@this::PowerStatus == 0x02) { testAddLog("ECU进入重启流程"); } }

压力测试扩展

void ExecuteStressTest() { // 可扩展： // 1. 连续发送10次复位请求 // 2. 随机间隔测试(50-500ms) // 3. 混合其他服务请求 }

时序校验逻辑

// 验证响应时序合规性 if(getTimer(responseTimer) < 200) { testAddCondition("响应时间：%dms", getTimer(responseTimer)); }

专家调试技巧：

在Graphics窗口添加观测信号：ECU::ResetStatus sysvar::DiagResponseTime 使用Diagnostic Console设置过滤条件：filter.id = 0x733 && (payload[0] == 0x51 || payload[0] == 0x7F) 添加总线监测断点：break if (this.id == 0x733 && this.byte(0) == 0x7F)
