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.
