摘要
越来越多的OEM正在开发ADAS功能,以提高汽车产品的竞争力。ADAS系统更新是研发过程中通常的做法,特别是在开发阶段。因此,有效、及时和准确的更新系统,并在开发过程中降低成本对于OEM是非常重要的。ODX(Open Diagnostic eXhange)数据描述了ECU(Electronic Control Unit)诊断内容、刷写和功能配置,OEM也可以使用ODX诊断数据来验证和刷写ECU。本文描述了一个基于ODX数据的高效且自动的刷写平台,可以自动地检查ADAS系统中应该更新的ECU,然后将ECU刷写至正确的软件版本,以保证ADAS中ECU的更新效率。
More and more OEMs are developing ADAS functionalities to increase competitiveness of vehicle products. ADAS system is very common to be updated, especially in development phase. Therefore, effective and accurate updating system, which decreases costs of timing and money during development, is necessary and important for OEM sides. ODX (Open Diagnostic eXhange) data describes ECU (Electronic Control Unit) diagnostic content, including flashing and coding, ODX is useful for OEM to validate and update ECU via diagnostic functionality as well. The platform, which provides effective and automatic updating, is described in this paper based on ODX data. It can check which ECU in ADAS system shall be updated, then flash ECUs with accurate software version synchronously to guarantee efficiency of updating for ECUs in ADAS.
