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.
The anti-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.
