A Two-Stage Pedal Sensation Simulator and Its Automobile Brake Pedal Mechanism

Abstract

The invention discloses a two-stage pedal feeling simulator and its automobile brake pedal mechanism. The brake pedal mechanism includes a mounting bracket, a brake pedal, a two-stage pedal feeling simulator and an inductive sensor. The inductive sensor is used to perceive the driver in advance. The braking intention of the driver, the pedal displacement sensor is used to accurately identify the driver's braking intention, and the pedal feeling simulator includes a shell, a first elastic component, a second elastic component, a brake push rod and an emergency switch. Compared with the prior art, this embodiment adopts the two-stage simulation mode in which the first elastic component and the second elastic component are the main functions, which can effectively simulate the operating feeling of the brake pedal mechanism, and has a simple and reasonable structure, convenient operation and quick response , which improves the stability, comfort and safety of braking, and has the functions of pre-identifying braking intention and emergency braking.

Description

technical field [0001] The invention belongs to the technical field of vehicle brake equipment, and in particular relates to a two-stage pedal feeling simulator and an automobile 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 electronically controlled braking system realizes the decoupli...

AI Technical Summary

Problems solved by technology

However, the magneto-rheological fluid pedal feeling simulator in the above invention and the piezoelectric pedal pressure sensor in the above invention all have problems such as complex structure, cumbersome control, high cost and difficult implementation, and both of them have not considered manufacturing Motion intention pre-recognition and emergency braking functions

So far, the two-stage pedal feel simulator with braking intention pre-recognition and emergency braking functions and its automotive brake pedal mechanism have been rarely mentioned.
