Bus Lecture 17: Real Vehicle Automation Testing System Based on LabVIEW

This system focuses on communication-related functions for real vehicles, conducting a rapid functionality survey. For IO operations, such as switching sensors, reminders are provided through a “popup + voice prompt” method, achieving semi-automation. Before the ECU is installed in the vehicle, we need to find ways to conduct HIL testing, such as basic functional logic … Read more

Essential ECU Diagnostics! The 'Keep Alive' Techniques 90% of Engineers Don't Know: 3 Tips to Avoid Session Timeouts and Deadly Pitfalls in Reset Operations

In automotive electronic diagnostics,the UDS protocol is the core tool for engineers to “communicate” with the ECU. Today, we will delve into two key services:Diagnostic Session Control (SID 0x10) and ECU Reset (SID 0x11), analyzing the underlying mechanisms and application techniques! 1. Session Control Service (0x10): How to Avoid “Disconnection”?? The ECU defaults to Safe … Read more
