Embodiment Construction

[0043] 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.

[0044] 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.

[0045] The disclosure provides a brake pedal simulator, a brake system of an automobile and a technical solution of the 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 reflected by the corresponding relationship between the pedal force, the pedal travel and the brake response time...

Abstract

The present disclosure relates to a brake pedal simulator, an automobile braking system and a vehicle. The brake pedal simulator includes a brake pedal, a booster motor, an assembly part, a first elastic member arranged at intervals along the axial direction on both sides of the assembly part, and The second elastic member, the rack and pinion mechanism located between the two second elastic members, the thrust structure that is hinged to the brake pedal and can sequentially drive the first elastic member and the second elastic member to expand and contract in the axial direction, the first elastic member Provide pedal preset force for the brake pedal, the output shaft of the booster motor can cooperate with the second elastic member through the rack and pinion mechanism to provide power assistance for the driving of the thrust structure, and the first elastic member is compressed by the thrust mechanism in the first working state In the second working state, the first elastic member and the second elastic member are compressed synchronously through the cooperation of the thrust mechanism and the booster motor. Therefore, a reliable braking feeling of the brake pedal is provided to simulate an accurate brake pedal force, which has the effects of good operation stability and quick response of the 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...
