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.
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
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 the
rear wheels.
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.
