Here’s how anti-lock works. Let’s say the road
is
wet.
You’re driving safely. Suddenly an animal jumps out
in
front of you.
You slam on the brakes. Here’s what happens with
ABS.
A
computer senses that wheels
are
slowing down.
If
one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at
both rear wheels.
‘Me anb-lock system
can
change
the
brake pressure faster
than any
driver
could. The computer
is
programmed to
make
the
most
of
available
tire
and road conditions.
You can steer around the obstacle while braking hard.
As
you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
