Here's how anti-lock works. Let's say the road
is
wet.
You're driving safely. Suddenly an animal jumps out i n
front of you.
You slam on the brakes. Here's what happens
with ABS.
A computer senses that wheels are slowing
down.
I f one
of the wheels is about to stop rolling. the computer will
separately work the brakes at each front wheel
and
at
the
rear wheels.
The anti-lock system can change the brake pressure
lister 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.
