Anti-Lock Brakes (ABS)- Page 178

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 wheel.

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.
