Sensor-Based Motorcycle Restrain System with an Integrated Automatic Brake System

This article focuses on the development and testing of a sensor-based motorcycle restraint system equipped with an automated braking mechanism. The system integrates ultrasonic sensors, a DC linear motor, and an Arduino microcontroller to enhance motorcycle safety by detecting obstacles and applying brakes automatically. A prototype was constructed using a wooden frame and bicycle wheels to emulate the motorcycle's dynamics. The braking system utilized a genuine motorcycle drum brake, and the DC linear motor was linked to activate the brake lever based on sensor feedback. LED strips and a buzzer provided visual and audible warnings, indicating the presence and proximity of obstacles. The system was tested under various conditions to evaluate its responsiveness, accuracy, and dependability. The findings revealed that the ultrasonic sensors provided precise distance measurements, allowing for a timely response in obstacle detection scenarios. The automatic braking mechanism demonstrated a 65% reduction in reaction time compared to manual braking, improving rider safety significantly. The system also managed to reduce the braking distance at speeds of 50 km/h, demonstrating its efficacy in emergency situations. Data collected during prototype testing indicated that the system effectively engaged the brake within a 10 cm detection range, issued appropriate warnings, and accurately monitored brake wear. Despite some limitations, such as environmental sensitivity and the prototype's use of simplified materials, the research underscores the system's potential to enhance motorcycle safety. Future recommendations include improving sensor reliability in adverse weather conditions, upgrading the prototype to mimic full-scale motorcycle dynamics, and incorporating additional features like traction control and rider-assist technology.
