The invention discloses an automobile emergency brake control method and equipment thereof, and belongs to the technical field of automobile brake control systems. An automobile emergency brake control method comprises the steps that a judgment module is started for calculation and judgment, and the triggering conditions are as follows: A1, an obstacle enters, no signal is monitored in an original brake assisting system, and according to the distance between the obstacle and an automobile, the automobile enters a first limit brake distance smaller than the sum of a reserved threshold value and a first limit brake distance smaller than the sum of a second brake assisting system; a2, an obstacle enters, it is monitored that an original brake assisting system has a signal, but the brake distance obtained through analog calculation when the vehicle decelerates to zero is smaller than the sum of the first limit brake distance of a second brake assisting system and a reserved threshold value; and A3, the distance when the obstacle appears is directly smaller than the sum of the first limit braking distance and the reserved threshold value. According to the emergency braking device, the braking time and the braking distance can be short under emergency conditions, so that the emergency braking device adapts to emergency braking under various emergency conditions, and the driving safety of a vehicle is ensured.

    本发明公开了一种汽车急刹车控制方法及其设备,属于车辆制动控制系统技术领域。一种汽车急刹车控制方法,启动判断模块进行计算判断,触发条件如下:A1:障碍物进入,未监测到原刹车助力系统有信号,根据障碍物和本车之间的距离进入小于第二刹车助力系统的第一极限刹车距离和预留阈值总和;A2:障碍物进入,监测到原刹车助力系统有信号,但车辆减速度至零的模拟计算的刹车距离小于第二刹车助力系统的第一极限刹车距离和预留阈值总和;A3:在障碍物出现的距离直接小于第一极限刹车距离和预留阈值总和。它可以实现在紧急情况下制动时间和制动距离短,以适应各种情况下的紧急情况的急刹车,确保车辆行驶安全。
