heal.abstract	In this thesis, the design and the development of a novel camber angle control sys- tem (CCS), applied on an electric prototype vehicle, is presented. The vehicle has a simple indepedent suspension structure. Thus, each wheel is attached to the vehicle body through an upper and a lower arm. After the installation of the CCS mechanism, the upper arms of the front wheels could be translated horizontally, adjusting the cam- ber angle of the front wheels. The Body Control Module (BCM) collects data from the several vehicle sensors, applies appropriate filters and sends essential information to the Central Control Module (CCM) of the vehicle. In the CCM, the major controller of the system is being excecuted. The controller reads the yaw rate and according to its current value, the desired camber angle is being calculated. The value of the desired camber angle is being forwarded to the CCS servo through the BCM. Con- forming to the theory, the proper camber angle adjustment could cause higher lateral forces. Accordingly, an increase to lateral acceleration should occur. Based on that hypothesis, simple circular maneuvers with constant longitudinal velocity and steering angle were designed for the mathematical proof of concept. In addition, a sinusoidal steering maneuver was designed as experiment for a more qualitative validation of the hypothesis.	en
