Electric bicycle preventive control handle and static brake detection system

Description: Prevents key accidents: A.One-handed riding → auto slow via sensor fusion. B.Brake wear → pre-ride check via vibration sensor; real-time % shown. Includes LCD, voice alerts, BeiDou GPS, battery check, app data. China regulation-ready, ideal for shared fleets.

This system uses an activation motor to stimulate the brake pads while a vibration sensor measures amplitude. Higher vibration means the pads are worn and not engaging properly; lower values suggest effective braking. Results are shown as percentages on an LCD screen mounted on the handlebar, with matrix-based voice alerts for real-time warnings and maintenance reminders. All components—including the sensor, motor, and ESP32 controller—are enclosed in waterproof, tamper-proof acrylic boxes. The ESP32 manages data collection, processing, and wireless transmission. A BeiDou GPS and communication module enables live positioning and remote fault alerts through a dedicated mobile app. Developed through multiple iterations, the system evolved from a wooden prototype to a robust, integrated version featuring spring-enhanced vibration detection, voice modules, and simplified four-wire installation. Target users include e-bike manufacturers, fleet operators, and individual consumers. Unlike vision-based systems, this physical vibration method works in all lighting conditions. Revenue comes from hardware sales, data services, and policy-aligned partnerships. Future plans include AI upgrades, smart city integration, and open API access.
