The invention discloses an extensible automobile lighting system based on an automobile body control unit. The extensible automobile lighting system is suitable for an automobile adopting the automobile body control unit. The system comprises a vehicle lamp control module, a driving module, a protection module and a vehicle lamp. The vehicle lamp control module is located in the vehicle body control unit, an input signal comes from the vehicle body control unit, and an output control signal is connected with the driving module through a bus. The driving module receives a control signal from the vehicle lamp control module and outputs a driving signal to be connected with the vehicle lamp through the protection module. The control signals of all the automobile lamps are concentrated in the automobile body control unit, the compatibility of automobile lighting control to different suppliers is improved, and the situation that the control signals are mistakenly triggered due to interference caused by system complexity is avoided. Meanwhile, the driving module and the vehicle lamp are arranged at physically adjacent positions, so that the driving reliability is ensured; and the dual protection mechanism of the control end and the driving end also enables the operation of the system to be safer.
本发明公开了一种基于车身控制单元的可扩展式汽车照明系统,适用于采用车身控制单元的汽车。本发明包括车灯控制模块、驱动模块、保护模块和车灯。车灯控制模块位于车身控制单元中,输入信号来自车身控制单元,输出控制信号通过总线连接驱动模块。驱动模块接收来自所述车灯控制模块的控制信号,输出驱动信号经保护模块连接所述车灯。本发明将所有车灯的控制信号集中在了车身控制单元中,提高了汽车照明控制对不同供应商的兼容度,还避免了控制信号因为系统复杂受到干扰导致误触发的情况。同时本系统将驱动模块和车灯置于物理上邻近的位置,保证了驱动的可靠性;控制端和驱动端的双重保护机制也使得本系统的运作更加安全。
