Deep learning-based vibration control of vehicle suspension on non-Gaussian roads using fuzzy logic

This paper presents an advanced vibration control method for vehicle suspension systems operating on non-Gaussian random road surfaces. The proposed approach integrates deep learning for precise road surface recognition with fuzzy logic control to dynamically adjust the suspension system’s stiffness and damping parameters. A dynamic model of the suspension system is developed, capturing the non-linear characteristics of the vehicle’s response to external disturbances. The deep learning model, based on Convolutional Neural Networks (CNN), predicts road surface conditions, including slope and curvature, using image data. The fuzzy logic controller then utilizes these predictions to optimize the suspension system in real-time, enhancing ride comfort and vehicle stability. Extensive simulations and real-vehicle tests demonstrate that the proposed method significantly reduces vibrations, improves ride quality, and ensures vehicle safety across diverse road conditions, showcasing its adaptability and robustness in fluctuating environments.
