AntiLock and ABS

Question 1

An Antilock Brake System (ABS) is?

Answer 1

Safety system that allows wheels to maintain traction with the road surface, prevents the wheels from locking up in panic stops. ABS works because sensors monitor wheel speed at a rate of 100 times per second.

Question 2

What are the 4 components of an ABS?

Answer 2

Wheel Sensors, Valves, Pump and Controller

Question 3

What is the function of the Wheel Sensors

Answer 3

the speed sensors, located at each wheel, collects information on wheel speed for ABS.

Question 4

What is the function of the Valves

Answer 4

there is a valve in each valve break line controlled by ABS- they have 3 positions. 1. Open, pressure moved right through brake. 2. Closed, valve blocks brake line. 3.partially open, valve releases some air.

Question 5

What does the Pump do?

Answer 5

: Because valve can release brake pressure. Pump brings pressure back up.

Question 6

What does the Controller do?

Answer 6

controller (ESC) collects info from wheel sensors, and if wheel loses traction, controller will limit brake force etc.

Question 7

What is the danger of the ABS system on a loose road surface?

Answer 7

the danger of the ABS is that on loose surfaces the stopping distance can increase, but it also increases vehicle control.
