Abstract:
With the escalating integration of Electronic Control Units (ECUs) in contemporary vehicles, the intricacy of vehicle networks is incessantly advancing. Diagnostic communication, as a pivotal facet within these networks, grapples with protracted development cycles and heightened intricacies. In a bid to augment software reusability and portability, this study meticulously scrutinized pertinent research and proffered an electric vehicle fault diagnosis system predicated on the Controller Area Network (CAN) bus, leveraging the diagnostic communication architecture advocated by the AUTOSAR standard. The integration of AUTOSAR seeks to pioneer an innovative software development paradigm for automotive fault diagnosis systems, thereby remedying extant limitations. The communication and diagnostic module of this study were instantiated using AUTOSAR, thereby obviating the necessity for developers to immerse themselves in hardware intricacies and communication implementations. This allows developers to focalize their efforts on crafting software features for fault diagnosis. Empirical results illustrate that the single-core CPU utilization rate of the proposed method in this article stands at ۴۰.۶۸%, with a fault detection time of ۰.۰۲۱۷. The success rate of fault detection is ۹۸.۷۰%, indicating an increase of ۱۲.۹۷% and ۸.۹۸% when compared to the CAN bus and structural analysis methods, respectively. Testing indicators are significantly mitigated, yielding more precise fault detection outcomes. The exploration of this avant-garde software development methodology in automotive electronic products markedly amplifies the efficiency of automotive troubleshooting system software, underscoring its potential for academic contribution and application in real-world scenarios.
