This project demonstrates how to create a straightforward model for an anti-lock braking system (ABS). It mimics the dynamic behavior of a vehicle when braking forcefully. The model represents a single wheel that can be repeated numerous times to represent a multi-wheel vehicle. • Researched thoroughly to build an optimized and efficient Simulink model • Designed and integrated the Simulink model and MATLAB code Show less
