摘要
在汽车电器网络中应用中央协调器能够避免由于单一电器故障而引发的汽车运行停止的问题,有着较强的使用优势。传统的汽车电器系统已经无法满足现阶段汽车电器系统的实际要求。随着现场总线技术的发展,基于中央协调式的汽车电器网络由于系统复杂程度较低,而受到了更多的关注。基于此,文章阐述了基于基本功能协调、智能化与故障协调、电源管理协调的三级串联中央协调在汽车电器网络中的应用。利用复数的中央协调器设计了基于冗余备份的中央协调器,并对其运行过程进行了阐述。应用结果显示,基于冗余备份的中央协调器能够提升驾驶员与乘客的驾乘体验,降低由于单个电器故障引发汽车整体运行停止的概率。
The application of the central coordinator in the automobile electrical network can avoid the problem of stopping the operation of the automobile caused by the failure of a single electrical appliance, and has strong use advantages. The traditional automotive electrical system can no longer meet the actual requirements of the current automotive electrical system. With the development of fieldbus technology, automotive electrical network based on central coordination has received more attention due to its low complexity. Based on this, this paper expounds the application of three-level series central coordination based on basic function coordination, intelligence and fault coordination, and power management coordination in automotive electrical network. A central coordinator based on redundant backup is designed by using complex central coordinators, and its operation process is described. The application results show that the central coordinator based on redundant backup can improve the driving and riding experience of drivers and passengers, and reduce the probability that the overall operation of the car stops due to a single electrical fault.
