The invention discloses a mistaken stepping prevention system and device for automobile emergency braking, and belongs to the technical field of automobile safety. The mistaken stepping prevention system comprises an accelerator pedal, a connecting rod and a pedal displacement sensor, the accelerator pedal is connected with the pedal displacement sensor through the connecting rod, and the accelerator pedal is connected with one end of the connecting rod through a positioning block; a fixing block is fixedly connected to the surface of the connecting rod, a mounting shell is fixedly connected to the surface of the fixing block, and a first sensor, a second sensor and a trigger rod are arranged in an inner cavity of the mounting shell; in an emergency, a guide rod is moved by mistakenly stepping on the accelerator pedal, and when the accelerator pedal is forcibly stepped on, a limiting ball mounted on the inner wall of a limiting plate through a limiting spring is retracted, so that the trigger rod in the mounting shell moves through a guide plate, and the first sensor and the second sensor are triggered; and if the triggering time interval of the two sensors is within the preset threshold range, a signal is sent to a braking system for emergency braking.

    本发明公开了一种用于汽车紧急刹车制动的防误踏系统及其装置,属于汽车安全技术领域,包括油门踏板、连杆和踏板位移传感器,所述油门踏板通过连杆连接踏板位移传感器,所述油门踏板通过定位块连接连杆一端,所述连杆表面固定连接有固定块,所述固定块的表面固定连接有安装壳,所述安装壳的内腔设置有第一传感器、第二传感器和触发杆;本发明通过在紧急情况下,误踩踏油门踏板,使导向杆移动,在用力踩踏板的时,限位板内壁通过限位弹簧安装的限位滚珠会进行收回,使安装壳内的触发杆通过导向板进行运动,从而触发第一传感器和第二传感器,如果两个传感器触发的时间间隔处于预设的阈值范围内,将会向制动系统发出信号,进行紧急制动。
