What’s Brake assist?

Mercedes-Benz driving simulator in

December, 1996

BAS premiered to the world

on the Mercedes-Benz S-Class and SL-S-Class

1998

2007

Mercedes-Benz became the first company

to make BAS standard equipment on all its

models.

the European Commission announced that it wanted Brake Assist to be included on all new models sold in the EU

A child or animal suddenly runs

into the road

When would brake assist be helpful?

Debris or large objects fall from an unsecured load into the roadway

Another vehicle swerves into the

driver's lane and either slows down or

stops.

When a curve in the road, or a hill, obstructs the driver's view of the road ahead.

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

booster

Advantages of Brake Assist

o Reduce the distance required to

come to a complete stop as it

applies optimum brake force almost

instantly

o Many studies claim reduction of more

than 20% in stopping distances

o Saving many lives by avoiding

3.1

Getting the most benefit possible from Brake

Assist

o First, you detect an object on or near the road

o Second, you assess the object to decide what kind of braking is

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

Improved effectiveness of brake assist technology

3.2

Disadvantages of Brake Assist

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

Excessive speed, intoxication, distraction, and fatigue  influence your reaction time,

“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.”

safety features like ABS and electronic stability
