Automobile brake pedal mechanism and pedal feel simulator thereof

Abstract

The invention relates to an automobile brake pedal mechanism and a pedal feel simulator thereof. The brake pedal mechanism comprises a brake pedal, a pedal displacement sensor, the pedal feel simulator, a microwave distance-measuring radar, a central processing unit and the like, wherein the pedal displacement sensor adopts two variable resistors for identifying the brake intention of a driver; the pedal feel simulator is based on a magnetorheological fluid principle; the central processing unit can controls the voltage volume of a coil and adjusts the damp of the simulator according to the pedal speed or distance information of front vehicles, people or barriers provided by the microwave distance-measuring radar, so that the driver has excellent operation feel, and the stability, comfort and safety of brake can be improved. Meanwhile, by changing the set value in the central processing unit, the damp output curve of the pedal feel simulator can be adjusted to meet requirements of different vehicle models or drivers. The automobile brake pedal mechanism and the pedal feel simulator thereof have the advantages of simple structure, quick response, good adaptability and the like, and is convenient in operation,.

AI Technical Summary

Benefits of technology

This patented technology allows for better regulation or controllability over how well the vehicle's dashboard felt analogue (peda feeling simulated) system works when no force needs them. It also includes features like sensors to detect road conditions, wheels speeds, and accelerations, which are used to determine if any obstacles have been passed beforehand without causing accidentally damaging their movements. Additionally, this design simplifies its construction while still providing effective performance under various driving scenarios such as acceleration/deceleration, cornering, etc., resulting in improved efficiency, responsiveness, and ease of use compared to previous designs. Overall, these technical improvements enhance the functionality and usability of the vehicle’ s electronic dashboards.

Problems solved by technology

This patented technical solution describes how current autonomously controlled vehicles require complex mechanisms for controlling their movements based upon sensors like cameras and radars. These solutions involve multiple parts and connections leading to potential issues when replacing them due to changes caused by environmental conditions. Additionally, they may lead to reduced reliability over time because each connection must be carefully tested before being put back onto production lines after installation.
