The design of exterior lighting is crucial for automotive manufacturers to ensure the visibility and safety of the driver. This article proposes a new strategy to control and diagnose one or more exterior lighting functions in electric vehicles by maximising the electrical faults that are detected and their transfer over a single-wire. The outcome is a decreased system cost and an additional method for vehicle lighting infrastructure control and diagnosis. Virtual simulation tools are used to explore the correlation between master-slave architecture and the effectiveness of the single-wire approach to comply with safety and regulatory demands. Safety-related and non-safety-related needs are explored to properly assess lighting functions, internal logic, and fault-case scenarios. Furthermore, assessing the viability of minimizing wire harness utilization while retaining the diagnostic capabilities for the controlled lighting sources, thereby simultaneously reducing the vehicle's overall weight. This approach aims to concurrently decrease the overall weight of the vehicle. This work has three main contributions: (1) the development of efficient and reliable lighting systems in electric vehicles, a critical factor for achieving optimal performance, ensuring customer satisfaction, meeting regulatory compliance, and enhancing cost-effectiveness in automotive lighting systems. (2) Framework for future development and implementation of lighting systems in electric vehicles. (3) Simulation of the hardware architecture associated with the system strategy to achieve the desired system strategy for effectively applying the single-wire approach.
汽车制造商而言，外部照明设计对于确保驾驶员的可见性和安全性至关重要。本文提出了一种新策略，通过最大化检测到的电气故障及其在单线传输，来控制和诊断电动汽车中的一个或多个外部照明功能。结果是降低了系统成本，并为车辆照明基础设施控制和诊断提供了一种额外方法。使用虚拟仿真工具来探索主从架构与单线方法的有效性之间的相关性，以符合安全和监管要求。探索与安全相关和与非安全相关的需求，以正确评估照明功能、内部逻辑和故障情况场景。此外，评估在保留对照明源的诊断能力的同时最小化线束使用的可行性，从而同时减轻车辆的整体重量。这种方法旨在同时减轻车辆的整体重量。这项工作有三个主要贡献：（1）开发电动汽车中高效可靠的照明系统，这是实现最佳性能、确保客户满意度、符合法规要求以及提高汽车照明系统成本效益的关键因素。（2）电动汽车照明系统未来开发和实施的框架。（3）模拟与系统策略相关的硬件架构，以实现有效应用单线方法的期望系统策略。
