Abstract

The enhancement of an active suspension system aims to optimize vehicle ride comfort, stability, and handling by dynamically adjusting suspension forces in real time. Unlike passive suspension systems, which rely on fixed mechanical components, active suspension systems utilize electronic sensors, actuators, and control algorithms to optimize damping and stiffness based on road conditions and driving behaviour. This project focuses on designing an electronically controlled active suspension system that integrates sensors and electromagnetic actuators to improve vehicle dynamics. A PID (Proportional-Integral-Derivative) controller is implemented to adjust suspension responses to varying road conditions. The system continuously monitors vehicle parameters such as body acceleration, wheel displacement, and road surface irregularities, ensuring optimal ride comfort and enhanced traction. Simulation and experimental analysis demonstrate that active suspension systems significantly reduce body vibrations, improve cornering stability, and enhance overall vehicle safety compared to traditional passive and semi-active suspension systems. The findings highlight the potential of active suspension technology in modern automotive applications, particularly in luxury vehicles, autonomous cars, and electric vehicles.
