Abstract

The invention discloses a linear adjustable pedal sense simulator and a brake pedal mechanism thereof. The brake pedal mechanism comprises a mounting bracket, a brake pedal, a linear adjustable pedal sense simulator and an inductive sensor, wherein the inductive sensor is used for perceiving the braking intention of a driver in advance; a pedal displacement sensor is used for correctly recognizing the braking intention of the driver; and the pedal sense simulator comprises a housing, a first elastic component, a second elastic component, a third elastic component, a driving connection mechanism, and an emergency switch. Compared with the prior art, the linear adjustable pedal sense simulator disclosed by the invention has the advantages that the second elastic component, the first elastic component and the third elastic component are sequentially adopted for main effect for simulation, so that the operating feel of people for the brake pedal mechanism can be effectively simulated; through the adoption of the driving connection mechanism, the adjustment to the characteristic curve of brake operation can be realized; the linear adjustable pedal sense simulator is compact in structure, convenient to operate, and quick to response; braking sense is adjustable; braking stability, comfort and safety are improved; and the functions of recognizing braking intention in advance and performing emergency brake are achieved.

Description

technical field [0001] The invention belongs to the technical field of vehicle brake equipment, and in particular relates to a linear adjustable pedal feeling simulator and a brake pedal mechanism thereof. Background technique [0002] The braking system is one of the important components of the automobile chassis, which is directly related to the comprehensive performance of the automobile and the safety of life and property. Although the traditional hydraulic and pneumatic braking systems can meet the requirements of the existing braking regulations, there are complex pipeline arrangements, relying on vacuum booster devices, slow braking response speed, non-active adjustment of braking torque, and difficulty in matching Other deficiencies such as system integration control are not suitable for the development requirements of automobiles, especially electric vehicle chassis integration control. [0003] The brake-by-wire system realizes the decoupling of the brake pedal me...
