Design for a semi-active preview suspension system using fuzzy-logic control and image processing techniques

摘要

The paper presents a fuzzy logic model for a semi-active car suspension model assisted with Image processing techniques to improve its performance and emphasizing its benefits over passive suspension system. The proposed system determines and operates over a range of damping constant required for the acquired road profile from the image. An Inertial Measurement Unit (IMU) sensor has been associated to determine suspension motion playing the role of a feedback sensor. This approach greatly reduces the rugged usage of a Magneto-Rheological damper while providing optimum vehicle stability and ride comfort.
