The invention relates to the technical field of vehicle lamp control, in particular to a vehicle lamp control system with self-adaptive current change and a control method thereof. The vehicle lamp control system with the current changing adaptively comprises a voltage detection unit used for detecting the power voltage of a vehicle body, and a low-dropout linear voltage stabilization unit used for reducing the power voltage and providing stable voltage for a microcontroller unit; the signal detection unit is used for detecting a vehicle body input signal and transmitting the filtered signal to the microcontroller unit; the automobile lamp driving unit is used for controlling on and off of an LED of an automobile lamp and feeding back fault information to the microcontroller unit; the step-up and step-down conversion unit is used for providing stable voltage for the vehicle lamp driving unit; and the microcontroller unit is used for judging whether a current reducing strategy is carried out or not and/or controlling the vehicle lamp driving unit to execute a lighting action according to the received data and signals. The automobile lamp in a low-voltage state can be kept lighted, and components in the automobile lamp are prevented from being damaged by large current.

    本发明涉及车灯控制技术领域,尤其是一种电流自适应变化的车灯控制系统及其控制方法。电流自适应变化的车灯控制系统,包括:电压检测单元,用于检测车身电源电压,低压差线性稳压单元,用于降低电源电压,为微控制器单元提供稳定电压;信号检测单元,用于检测车身输入信号,并把经过滤波后的信号传递给微控制器单元;车灯驱动单元,用于控制车灯的LED亮灭,并将故障信息反馈给微控制器单元;升压降压转换单元,用于给车灯驱动单元提供稳定的电压;微控制器单元,根据接收到的数据和信号,判断是否进行降低电流策略和/或控制车灯驱动单元执行点灯动作。可以使处于低压状态下的汽车车灯能保持点亮,并避免大电流损坏车灯内部元器件。
