Road quality across Bangladesh varies drastically from smooth urban segments to severely degraded rural pathways, creating persistent challenges for vehicle stability, ride comfort, and long-term mechanical reliability. Most vehicles on these roads still rely on passive suspension systems that cannot respond to changing surface conditions, resulting in excessive vibration, component wear, and reduced driving comfort.
This study introduces a practical and locally adaptable smart suspension tuning system specifically tailored to the diverse road environment of Bangladesh. The proposed system utilizes low-cost accelerometers and vibration sensors to continuously interpret road roughness. The collected data is processed through an adaptive control mechanism capable of adjusting suspension stiffness in real time. In parallel, a machine learning model is investigated to forecast upcoming surface irregularities from historical sensor patterns, allowing the system to prepare the suspension configuration before encountering rough terrain.
A prototype unit was installed and evaluated on representative Bangladeshi road surfaces, including cracked asphalt, pothole-ridden segments, and unpaved stretches. The initial trials demonstrated a noticeable reduction in transmitted vibration levels and a clear improvement in ride comfort and vehicle stability. The findings indicate that an affordable and scalable suspension solution can be developed using readily available components, offering a bridge between advanced automotive technologies and the practical requirements of developing regions.
Overall, this work emphasizes the importance of localized engineering innovations and highlights how context-specific automotive technologies can contribute to safer, smoother, and more durable vehicular operation in resource-constrained environments.
