Abstract

The invention discloses a three-stage pedal feeling simulator and its automobile brake pedal mechanism. The brake pedal mechanism includes a mounting bracket, a brake pedal, a three-stage pedal feeling simulator and an inductive sensor. The inductive sensor is used to perceive the driver in advance. The pedal displacement sensor is used to accurately identify the driver's braking intention. The pedal displacement sensor includes a housing, a brake push rod, a first elastic component, a second elastic component, a third elastic component and an emergency switch. Compared with the prior art, the present invention adopts a three-stage simulation method of single elastic component, double elastic component and third elastic component, which can effectively simulate the manipulation feeling of the brake pedal mechanism, and has simple and reasonable structure, convenient operation, quick response, and improved The stability, comfort and safety of braking, and it 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 three-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 decoup...
