What’s Brake assist?
“Brake assist is a safety feature that is designed to
help drivers apply the right amount of force to their

brakes during panic stop situations.”

Working Principle

Mechanical systems include a locking
mechanism that activates when the
valve stroke –which is directly related
to how far the brake pedal is depressed
- passes a critical point.

Once a critical threshold is passed, the
locking mechanism switches the source of
braking power from the brake piston valve
(which is exposed to the depression of the
brake pedal) to the brake assist booster: a
vacuum that increases brake force by

allowing atmospheric pressure to enter the

Advantage –
Disadvantage of
Brake assist


o

Reduce the distance required to
come to a complete stop as it

3.1

applies optimum brake force almost
instantly.

Advantages of Brake
o

Many studies claim reduction of more
than 20% in stopping distances

o

Saving many lives by avoiding
accidents.

Assist


o
o

First, you detect an object on or near the road.
Second, you assess the object to decide what kind of braking is

3.2

appropriate and initiate a response.

o

Third, you modify your brake pressure in response to how
successful your initial braking was, how fast you are still going, and
how close you are to the object in your path.

o

Fourth, you come to a complete stop – hopefully before a collision.

Getting the most benefit
possible from Brake

Improved effectiveness of brake assist technology


Brake assist system will either not activate at all, or fail to work as well as it

could

Brake assist has no way of seeing
obstacles ahead

Disadvantages of Brake
Assist

Excessive speed, intoxication, distraction,
and fatigue  influence your reaction time,
effect your ability to be aware


“Intelligent Emergency Braking monitors the surrounding area in

front of the car for vehicles and pedestrians, helping to avoid or
reduce damage caused by collisions.”
