What is Abs?
Abs is fully-formed as an anti-lock braking system, a safety
braking system that does not allow vehicles to skid on land. Abs don't lock the
wheels while braking which maintains tracking contact with the surface of the
road and thus allows the driver to maintain control over the vehicle.
How does ABS operate?
Abs includes an electronic control unit and wheel sensors
and hydraulic valves within the brake hydraulics. Ecu monitors the rotational
speed of each wheel; if founded any wheel rotating at a slow speed compared to
the speed of the vehicle it causes the valve to reduce hydraulic pressure to
the affected wheel thus reducing the braking force on that wheel. The wheel
then turns faster. if the ECU found that the wheel rotates faster than other
wheels it causes the valve to increase hydraulic pressure to slow down the
wheel.
Types of ABS
Single-channel ABS
These are mainly found on the rear wheels with one valve
which controls the wheel and a speed sensor will present at the rear axle.
Dual-channel ABS
This technology uses a sensor at each wheel of the vehicle
(two-wheeler or four-wheeler) with one control valve for each wheel. for
two-wheeler and one valve each for front and the rear wheel as pair in
four-wheelers.
Three-channel three-sensor ABS
Found with four-wheel ABS, has a speed sensor and a valve
for each of the front wheels, with one valve and one sensor for both rear
wheels and speed sensor, is positioned at the rear axle. To achieve maximum
braking force this system provides individual control over the front wheel.
Three-channel four-sensor ABS
Speed sensor will
present for all four wheels and a separate valve for front wheels and only one
valve for rear wheels.
Four-channel four-sensor ABS
Four sensors and four valves are given respectively for four
wheels. The controller monitors all wheels individually and makes sure of
achieving maximum braking force.
