The invention relates to the field of vehicle lamp control, in particular to a sectional type corner lamp control system which is more energy-saving and more convenient to control compared with an existing corner lamp control system and a control method thereof. The sectional type corner lamp control system comprises a photosensitive sensor (1), a steering wheel angle sensor (2), an LDO power supply module (3), an MCU chip (4), a CAN transceiver (5), an LED driving chip (6), a constant current source module (7) and a multi-particle LED corner lamp module (8). The MCU chip (4) is electrically connected with the LDO power supply module (3), the MCU chip (4) is in signal connection with the CAN transceiver (5), the LDO power supply module (3) is further electrically connected with the CAN transceiver (5), the photosensitive sensor (1) and the steering wheel angle sensor (2) are respectively connected with the MCU through a CAN bus, and the MCU chip (4) is connected with the LED drive chip(6) through a UART bus.The LED driving chip (6) is in electrical signal connection with the multi-particle LED corner lamp module (8).

    本发明涉及车灯控制领域,尤其涉及一种相比现有的角灯控制系统更加节能,控制更加便捷的分段式角灯控制系统及其控制方法,包括光敏传感器(1)、方向盘角度传感器(2)、LDO供电模块(3)、MCU芯片(4)、CAN收发器(5)、LED驱动芯片(6)、恒流源模块(7)和多颗粒LED角灯模组(8),所述MCU芯片(4)与LDO供电模块(3)电连接,所述MCU芯片(4)和CAN收发器(5)信号连接,所述LDO供电模块(3)还与CAN收发器(5)电连接,所述光敏传感器(1)和方向盘角度传感器(2)分别通过CAN总线与MCU连接,所述MCU芯片(4)与LED驱动芯片(6)通过UART总线相连,所述LED驱动芯片(6)与多颗粒LED角灯模组(8)电信号连接。
