Influence of speed and adhesion coefficient on the brake effectiveness of the ABS brake system on cars

Abstract

Currently, most personal cars applied Anti-lock Braking Systems (ABS) to meet increasing requirements for speed and safety when operating. Braking efficiency is one of the criteria to evaluate the quality or reliability of the braking system through criteria such as braking distance, deceleration when braking, and braking force applied to the wheels. This study aimed to present the process of investigating the influence of vehicle speed and road surface adhesion coefficient on the effectiveness of ABS. This simulation based on automotive theory combined with Matlab/Simulink to visually describe the relationship between variables in the ABS. Simulation resulted from Matlab/Simulink showed that braking distance and braking time were proportional to the speed before braking and inversely proportional to the adhesion coefficient. This simulation result was completely consistent with the published experimental results. It showed that this study was reliable and can be applied to calculate and simulate specific types of cars under specific conditions.
