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] 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 thrust structure and a plurality of elastic members, and some of the elastic members in the plurality of elastic members are braking The pedal provides the pedal preset force, and the thrust structure is hinged to the brake pedal and cooperates with the part of the elastic parts for sequentially driving the part of the elastic parts and the rest of the elastic parts to expand and contract in the axial direction, and the brake pedal The simulator has a first working state and a second working state. In the first working state, the part of the elastic member is compressed, and in the second working state, the part of the elastic member and the rest of the elastic members are compressed synchronously. When the brake pedal is stepped on, by sequentially driving some of the elastic members and the rest of the elastic members to expand and contract in the axial direction, a reliable braking feeling of the brake pedal can be provided, and an accurate brake pedal can be simulated It 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...
