The invention provides a pedal simulator for an electric booster. The pedal simulator comprises a flange plate, a push rod and a damping piece, the two ends of the push rod are connected with a brakemaster cylinder and a pedal respectively, the push rod and the damping piece are arranged in a main cavity defined by the inner wall of the flange plate, and the push rod can be driven by the pedal toslide in the main cavity. The push rod can further convert friction force generated between the damping piece and the flange plate in the sliding process into pedal feeling and/or hysteresis feelingand transmit the pedal feeling and/or hysteresis feeling to the pedal. The damping piece and the spring provide a layered pedal feeling for the user when the user steps on the pedal, the damping pieceand the second friction cavity with the conical surface provide a gradually increased damping feeling for the user, and when the user loosens the pedal, different hysteresis feelings along with the change of the pedal stroke can be generated, and excellent use experience is provided for the driver by the electric booster.

    一种电动助力器使用的踏板模拟器,包括法兰盘、推杆和阻尼件,所述推杆的两端分别与制动总泵和踏板连接,所述推杆和所述阻尼件设于由所述法兰盘的内壁围成的主腔体内,所述推杆能够在所述踏板的驱动下在所述主腔体内滑动,所述推杆还能够将滑动过程中所述阻尼件与所述法兰盘之间产生的摩擦力转化为踏板感和/或滞后感并传递至所述踏板。本发明通过阻尼件和弹簧在使用者踩踏踏板时为使用者提供具有层次的踏板感,通过阻尼件和具有锥面的第二摩擦腔为使用者提供逐渐增加的阻尼感,在使用者松开踏板时能够产生随踏板行程的变化而不同的滞后感,为使电动助力器为驾驶员提供了优秀的使用体验。
