摘　　要：文章梳理了自动驾驶中主动制动技术的主流执行方案,分析了各执行方案对驾驶员输入制动和自动制动的响应机理,明确了制动执行器内部表征驾驶员制动意图和自动制动意图的参数,提出使用制动执行器内部参数准确判断驾驶员制动接管的方法,即通过实际主缸压力值超出自动制动目标液压一定阈值,或响应驾驶员制动输入的目标电机转速超出自动制动的目标电机转速一定阈值,判断自动制动过程中驾驶员通过制动接管车辆的方法。In this paper,the mainstream auto brake solutions for auto driving are summarized,the mechanism of each solution to honor diver input brake and auto brake are analyzed,the brake actuator internal parameters standing for driver brake intention and auto brake intention are identified,and a method to accurately judge driver brake overrides through brake actuator internal parameters is proposed by the comparison between actual master cylinder pressure and auto brake target pressure,or the comparison between the target motor speed of driver input brake and the target motor speed of auto brake.
