Automotive Electronic Controller Diagnosis Technology

With the development of new energy, the new energy field is becoming more and more popular. Hybrid vehicles are selling well. Photovoltaics, hydrogen energy, lithium batteries, automatic driving control, and other fields will be one of the hot spots in the future. The information shared this time is the technical document - automotive electronic controller diagnostic technology (including detailed specification documents), which is mainly used for new energy vehicle software development or MBD software development (MBD), etc. It can be used for project development, personal learning guidance, etc., including: development tool source code, instruction manual and data information description, etc. It is suitable for system engineers and software engineers.

Background:

The UDS (Unified Diagnostic Services) diagnostic protocol is a diagnostic communication protocol in the automotive electronic ECU environment, specified in ISO 14229. It is derived from ISO 14230-3 (KWP2000) and ISO 15765-3 protocols. The word "unified" means that it is an "international" rather than a "company-specific" standard. So far, this communication protocol is used in almost all new ECUs manufactured by OEM Tier 1 suppliers. These ECUs control various functions of the vehicle, including electronic fuel injection systems (EFI), engine control systems, transmissions, anti-lock brake systems (ABS), VCUs, BMSs, MCUs, etc.

Note: The design description file + script file will be published in the second issue of the personal planet account and is under preparation.

The market demand is large, and the industry is still in a booming development stage. The salary and benefits are excellent, and it is worthy for the majority of development experts to continue to study in depth and for engineers who have switched careers to learn. It requires a certain understanding and knowledge of the entire vehicle architecture, algorithms, and the operating mechanisms of each ECU unit. It requires experience, is relatively difficult, and requires lifelong learning. It has a high threshold, a wide range of applicability, strong portability, a wide range of employment, high salary and benefits, etc.
