The invention relates to an intelligent automobile brake lamp system and a working method thereof. The system comprises a brake lamp, a control module, a wheel speed acquisition module and a brake pedal signal sensor. A brake signal output end of the brake pedal signal sensor and an angular velocity signal output end of the wheel speed acquisition module are connected with a signal input end of the control module; the control module is used for processing the angular velocity data acquired by the wheel speed acquisition module, calculating the current intensity of the brake lamp and controlling the brightness of the brake lamp according to the current intensity. The vehicle speed change rate is truly fed back through the wheel speed change, the rear vehicle is effectively warned corresponding to different working states of the brightness change of the brake lamp, and the warning performance of the rear vehicle is improved; and after the vehicle stops, the vehicle speed change is 0, and the brightness of the brake lamp is the lowest, so that the interference on the rear vehicle caused by the too dazzling brake lamp due to the operation of stepping on the brake for a long time when the red light is waited is effectively avoided.

    本发明涉及一种智能汽车刹车灯系统及其工作方法,该系统包括刹车灯、控制模块、轮速获取模块和制动踏板信号传感器;制动踏板信号传感器的刹车信号输出端、轮速获取模块的角速度信号输出端均与控制模块的信号输入端相连接;控制模块对轮速获取模块获取的角速度数据进行数据处理,计算出刹车灯的电流强弱,并根据电流强弱控制刹车灯的亮度。本发明通过轮速变化真实反馈车速变化率,对应刹车灯亮度变化的不同工作状态,有效的警示后车,对后车警示性提升;并且在车辆停止后车速变化为0,刹车灯此时亮度最低,有效的杜绝了诸如等红灯时长踩刹车的操作,刹车灯太刺眼对后车带来的干扰。
