This paper proposes a model reference adaptive control (MRAC) design for vehicle active suspension systems with unknown spring stiffness and damping coefficients with the aim of improving the performance of suspension systems. A mathematical model of a half-car active suspension system is first presented, then a reference model of a half-car suspension system that utilizes the skyhook damping concept is proposed.

The effect of the asymmetric damper on the vertical acceleration of the driver’s body, suspension deflection and tire dynamic load were studied thoroughly in order to provide suggestions for choosing damping parameters while building a bus’s suspension system. The vehicle model with three DOFs exposed to random road profiles was employed to investigate the dynamic responses for both two cases of linear symmetric and two-stage asymmetric dampers.

The increasing use of Intelligent Transport System (ITS) can enable very close vehicle spacings which generally results in a net drag reduction for the resulting convoys. The majority of vehicle development has, to date, been for vehicles in isolation, thus the study of interaction effects is becoming increasingly important. The main objective of this research is to investigate the use of Computational Fluid Dynamics (CFD) for understanding convoy aerodynamics and to further the understanding of airflow interaction between vehicles via CFD.

The main focus of this thesis is on the application of a model predictive control (MPC) method to devise an ABS for a BBW vehicle. Unlike the traditional ABS control algorithms which are based on a trial and error method, the MPC based ABS algorithm aims to utilizes the behaviour of the model to optimize the wheel slip dynamics subject to system constraints. Performance of the proposed wheel slip controller is validated through Software-in-the-Loop (SiL) and Hardware-inthe-Loop (HiL) simulation.

In this present paper, the road profiles are generated according to the ISO 8606:2016 standard to compare the differential of the road profile when changing the conditions. The semi-active suspension techniques are the solution to this problem and capable of reducing road vibrations effectively. The vertical quarter car model is installed with semi-active suspension system using Electrorheological shock absorber (ER damper) also considered to study the response of the vehicle to the road profile.
