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 axially disposed on one side of the fitting portion and connected to each other, and a thrust structure hinged to the brake pedal and cooperating with the first elastic member to drive the first elastic member and the second elastic member while telescoping in the axial direction. The first elastic member and the second elastic member cooperate together to provide a pedal preset force to the brake pedal, and the output shaft of the booster motor is cooperated with the second elastic member through a screw mechanism to be able to provide a booster force for driving the thrust structure. The invention 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...
