The invention discloses a pedal simulator of a large vehicle control assisting system. The pedal simulator comprises an HCU block body, a groove is formed in the HCU block body, an outer piston is installed in the groove, an installation groove is formed in the outer piston, and an inner piston is connected into the installation groove. According to the pedal simulator, a driver steps on the pedal, a hydraulic system is started, hydraulic oil enters an oil inlet into a first groove to extrude the outer piston and drive the outer piston to move, a light-load spring is stressed and extruded and feeds back force to the pedal, the driver can feel feedback force of the pedal simulator, the outer piston continues to move to make contact with the inner piston, and the inner piston is driven to move, the heavy-load spring is extruded by force and feeds back the force to the pedal, a driver can feel the feedback force of the pedal simulator, the feedback of pedal feeling during braking is further enhanced, the feedback of the pedal feeling during braking is good, the structure is stable, and the device is convenient to use.

    本发明公开了一种大型车辆控制助力系统踏板模拟器,包括HCU块本体,所述HCU块本体内开设有凹槽,所述凹槽内安装有外活塞,所述外活塞内开设有安装槽,所述安装槽内接有内活塞。本发明中,驾驶员脚踩踏板,启动液压系统,液压油进入进油口至第一槽内对外活塞进行挤压,驱动外活塞运动,轻载弹簧受力挤压并将力反馈至踏板上,驾驶员可以感受到踏板模拟器的反馈力,外活塞继续运动与内活塞接触,驱动内活塞运动,重载弹簧受力挤压并将力反馈至踏板上,驾驶员可以感受到踏板模拟器的反馈力,进一步增强制动时踏板感的反馈,制动时踏板感的反馈较好,结构稳定,便于装置的使用。
