Simulation of the ABS Braking System Behavior in Critical Faults

This article presents the simulation of critical faults of the anti-lock braking system (ABS) using a mathematical model of a vehicle room, which simulates the dynamics of a car during rough braking with abnormal system operation. For this, 5 scenarios were proposed: system with normal operation, fault in the hydraulic actuator, fault in the ECU, that is, deviation in the system, fault in the vehicle speed sensor and fault in the tire speed sensor. These proposed scenarios identify events and factors that degrade the operation of the system, in this case the ABS system increases the distance and the braking time that can cause the loss of control of the vehicle. Finally, an analysis and comparison of the scenarios is carried out
