The invention relates to vehicle lamp power supply management, and discloses a vehicle lamp power supply management system, which comprises a control unit and a power supply switch connected between each functional lamp and the control unit, the input end of each power supply switch is connected to the power end of the corresponding function lamp, the output end is connected to the power end of the control unit, and the control end is connected to the output port of the control unit; the power supply end of each functional lamp is connected to one input port of the control unit, and the fault state signal of each functional lamp is connected to one input port of the control unit; and the control unit is suitable for controlling the on-off of each power supply switch according to the combination of each power-on state signal and each fault state signal, so that the current flowing through any function lamp in the fault state is smaller than or equal to an alarm current set value. The invention further discloses a vehicle lamp power management method, a vehicle lamp system and a vehicle. The vehicle lamp power supply management system can give an alarm to a vehicle body in time when a failed functional lamp is used, so that the driving safety is ensured.
本发明涉及车灯电源管理,公开了一种车灯电源管理系统,包括控制单元和连接在各功能灯和控制单元之间的供电开关;各供电开关的输入端连接至与其对应的功能灯的电源端,输出端连接至控制单元的电源端,控制端连接至控制单元的输出端口;各功能灯的电源端分别连接至控制单元的一个输入端口,各功能灯的故障状态信号分别连接至控制单元的一个输入端口;控制单元适于根据各上电状态信号和各故障状态信号的组合来控制各供电开关的通断,使流经处于故障状态的任一功能灯的电流小于或等于告警电流设定值。本发明还公开了一种车灯电源管理方法、车灯系统及车辆。本发明的车灯电源管理系统在使用出现故障的功能灯时能够及时向车身报警,保证行车的安全。
