Due to the strength of modern cars and their
lightness in weight compared to relatively old cars,
manufacturers must consider the safety of passengers
through the brakes. Therefore, anti-lock braking systems
are used for these modern cars to prevent the wheels
from locking up after applying the brakes. The car
model has a non-linear shape. The control unit shall
provide the tuned torque necessary to maintain the
optimum value of wheel slip. In this paper to instruct
fuzzy PID controllers to improve performance control of
anti-lock brake systems compared to conventional PID
controllers. An improved anti-lock braking system(ABS)
that uses a vehicle quarter model and brake actuator.
The car model is derived and simulated linearly towards.
three types of controller: relay controller, genetically
tuned linear PID and fuzzy PID-type controller. The
quality of the anti-lock braking system is assessed in the
Matlabsystem by the braking distance and the
longitudinal slip coefficient of the vehicle. The fuzzy
regulator showed the best characteristics for the antilock system model, reducing the braking distance by up
to 10% compared to a conventional PID and by more
than 30% compared to a relaycontroller. Practical
significance: the proposed control algorithm is promising
for implementation in an anti-lock system in real time
