Description

In this book, we develop an idea around a type of control system based on fuzzy logic to help a driver maintain the kinetic balance of the vehicle. After a brief discussion on the vehicle dynamics stability theory in the first chapters, we introduce the main idea together with simulation results and hardware implementation. The main idea is to investigate the vehicle dynamics instability based on the fuzzy analysis of the vehicle CG (center of gravity) behavior and to use sensors and actuators in order to coordinate suspension, brakes and steering system in critical situations. An advantage of this controller is that it doesn't interfere with the driver's habit in vehicle control and it resumes functioning only in critical moments. Using various actuators and sensors, we introduce a new approach to detect vehicle dynamics instability and the turnover threshold.
