摘要
成本是推广全分布式车身电器系统的主要制约因素。该文提出一种全分布式电器系统结构,建立了与之相关的附加成本模型,包括线束成本模型和控制器成本模型。对一辆国产客车的车身电器系统进行全分布式改造设计,利用该模型,对线束材料、人力、控制器等关键成本因素进行了分析,验证成本模型的有效性。该模型预测的结果表明:对于未来全分布式汽车电器系统,考虑到一方面铜材、人力价格会上涨,另一方面电子器件成本将降低;因此,总体附加成本不仅可以达到平衡,而且可比现有的分布式系统低。
Cost is the main obstacle for use of completely distributed automotive body electrical systems. A complete-distributed electrical/electronic system architecture was proposed and a related additional cost model was established, which consists of a harness cost model and an electronic control unit cost model. The electrical system was applied to an urban shuttle bus to analyze the cost of harness material, labor, and control unit. The proposed model proves to be effective. The results predicted using the model show that, for the completely distributed electrical system in future, on one hand, the cost of copper and labor will increase, and on the other hand, the cost of electronic devices will decrease with time. Therefore, the additional cost will not only reach its balance, but will be lower than that of the existing systems.
