Embodiment Construction

[0045] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0046] In the present disclosure, the used orientation words such as "inside and outside" generally refer to the inside and outside of the outline of the corresponding part unless stated to the contrary.

[0047] like Figure 1 to Figure 19 As shown, the present disclosure provides a technical solution of a brake pedal simulator, an automobile braking system and a vehicle. The brake pedal simulator of the present disclosure realizes simulating the characteristics of the brake pedal through the elastic member and the braking method. Here, the characteristics of the brake pedal are usually through the correspondence between the pedal force, the pedal travel an...

Abstract

A brake pedal simulator, a vehicle braking system and a vehicle are provided, wherein the brake pedal simulator includes a brake pedal, a booster motor, an assembly part for fitting to a vehicle body,a first elastic member and a second elastic member disposed axially on one side of the fitting portion and at least partially overlapping with each other in the axial direction, and a thrust structure hinged to the brake pedal and cooperating with one end of the overlapping portion of the first elastic member and the second elastic member to be capable of driving the first elastic member and thesecond elastic member while telescoping in the axial direction. The first elastic member and the second elastic member cooperate to provide a pedal preset force to the brake pedal, and the output shaft of the booster motor cooperates with the one end of the overlapping portion of the first elastic member and the second elastic member through a screw mechanism so as to be able to provide the boosting force to the thrust structure. This provides a reliable braking feel of the brake pedal and simulates an accurate brake pedal force, and has the effects of good operation stability and corresponding quick brake pedal.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle braking systems, and in particular, relates to a brake pedal simulator, a vehicle braking system and a vehicle. Background technique [0002] In existing vehicles, especially in electric vehicles, part of the braking system cancels the hydraulic or mechanical connection between the brake pedal and the brake of the traditional braking system, so that the driver cannot directly perceive the feedback to the brake pedal when braking. Braking reaction, thus losing the braking feel of traditional braking systems. Among them, the brake feeling refers to the comprehensive feeling including the pedal brake feeling, the vehicle brake deceleration felt by the driver, the auditory brake noise and the visual vehicle deceleration and many other factors. Among them, the pedal brake feel for the most important part. For the above-mentioned braking system, a brake pedal simulator is usually added to sim...
