Embodiment Construction

[0049] 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.

[0050] 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.

[0051] Such as 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...

Abstract

A brake pedal simulator, a vehicle braking system and a vehicle are provided. The brake pedal simulator includes a brake pedal, a booster motor, an assembly portion, a first elastic member and a second elastic member disposed on one side of the assembly portion in the axial direction and partially overlapping with each other in the axial direction, and a thrust structure hinged to the brake pedaland cooperating with the first elastic member to sequentially drive the first elastic member and the second elastic member to telescopically retract in the axial direction. The elastic resilient member provides a pedal preset force to the brake pedal, The output shaft of the booster motor is cooperated with the first elastic member through a rack and pinion mechanism so as to be able to provide assistance to the thrust structure, the first elastic member is compressed through the thrust mechanism in a first working state, and the first elastic member and the second elastic member are compressed synchronously through the cooperation of the thrust structure and the booster motor in a second working state. 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...
