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 the
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.
