The invention provides a linkage control method for automobile emergency braking. The linkage control method for automobile emergency braking comprises the steps that under the condition of emergencybraking, whether a dynamic EPB deceleration condition is met or not is detected if a hand brake is started to work; if so, the EPB sends a braking deceleration request to an ESC; and the ESC performspressure buildup and speed reduction on each brake wheel of the automobile. By means of the linkage control method for automobile emergency braking, the hand brake and the ESC perform linkage control,the emergency braking deceleration is effectively increased, the emergency braking distance is shortened, and meanwhile, the phenomenon that wheels of an automobile are locked and cannot be controlled is avoided.
本发明提供了一种汽车应急制动的联动控制方法,该汽车应急制动的联动控制方法包括:应急制动情况下,若手刹启动工作,检测是否满足动态EPB减速条件;若是,则EPB发送制动减速请求至ESC;ESC对汽车各制动轮进行建压减速。通过上述的汽车应急制动的联动控制方法,手刹与ESC联动控制,有效提高了应急制动减速度,缩短了应急制动距离,同时防止了车辆出现车轮抱死而不可控的现象产生。
