Development of a system that changes the speed of the motor for a given radius of curvature of an autonomous car while taking turn

Abstract

This work endeavors to create a system capable of autonomously regulating a car’s speed while navigating turns, based on the curvature of the road. The primary objective is to bolster the safety and stability of autonomous vehicles by curbing excessive speeds during turns, thereby mitigating the risk of accidents such as loss of control or rollovers. The approach blends theoretical analysis with practical application, involving computations to ascertain the ideal speed for a given curve radius. Factors such as vehicle mass, wheel specifications, and centrifugal and gyroscopic forces are considered in these calculations. Subsequently, an algorithm is devised and implemented using Arduino Uno and programmed within the Arduino IDE software environment. The system employs sensors to monitor the motor’s speed and adjust the motor’s speed accordingly. Both simulated scenarios and real-world experiments validate the system’s efficacy in maintaining safe speeds during turns. The study concludes by underlining the potential of this system to heighten the safety and dependability of autonomous vehicles, while also proposing future avenues for research, such as integration with broader autonomous driving frameworks and field testing across diverse environmental conditions.
