摘要
车载智能供电网络包含智能电源管理、功率电网、信号电网三部分。对车载电源进行动态管理,从系统层面上解决能量控制和电池管理的问题。功率电网和信号电网需要对整车用电器进行分区供电,进而实现供电监测和故障诊断,保证用电安全。信号电网独立于功率电网,拥有独立的电源和搭铁,降低强电对信号传输的干扰,进而提高控制器的准确性和稳定性。
The intelligent vehicle power supply network consists of three parts： intelligent power management,power supply network and signal supply network. Dynamic management of vehicle power supply gives a method to solve the problem of energy control and battery management from the system level. The power supply network and the signal supply network need to partition all loads of the whole vehicle, realize power supply monitoring as well as fault diagnosis to ensure power safety. The signal supply network has independent power and ground, it will reduce the influence of large current on the signal, and improve the accuracy and stability of controllers.
