The invention belongs to the automobile safety field and in particular relates to an automobile deceleration safety system. The automobile deceleration safety system comprises a tail light for prompting a vehicle behind the vehicle; a buzzer for reminding of a driver; an accelerometer for detecting the accelerated speed of the vehicle; a gyroscope for detecting the pitch angle of the vehicle; a millimeter-wave radar for detecting the quantity, position, distance and speed of vehicles behind the vehicle; and a controller for processing information from all units and a sensor and generating control information. When the vehicle running at a high speed has a small opening degree of an accelerator pedal and a brake pedal is not treaded, a vehicle behind the vehicle cannot observe the deceleration of the vehicle easily. According to the potential risk, the automobile deceleration safety system is designed and has relatively high universality and reliability. 本发明属于汽车安全领域，具体涉及种汽车减速安全系统。它包括用于提示后方车辆的车尾灯；用于提示驾驶员的蜂鸣器；用于
