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. The computer
separately works 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.
