Although the reasons for
this are unclear, the solution is relatively simple: use technology
to design a system which can recognize emergency braking (whenever
the pedal is being depressed very quickly), then react with
split-second electronic speed to apply full power brake boost
Tests showed that 99
percent of drivers were slow in applying the brakes or only applied
full brake pressure when it was too late.
The new Mercedes-Benz brake
assist system may provide the critical difference between an
accident and a close call because the electronic system can react
far faster than any human.
How It Works
Brake assist is a driver-adaptive
system which learns each driverís braking habits by using
electronic sensors to monitor every movement of the brake pedal and
feed information to a mini-computer.
As a result, the system can instantly
recognize when the driver pushes the brake pedal quicker than
If it ever reads pedal speed signals
which it determines to be emergency braking, the computer instantly
applies an electronic valve on the brake booster system for full
braking. The wheels do not lock because of the presence of the
standard ABS anti-lock brakes, so that the new Mercedes-Benz brake
assist system takes advantage of the safety benefits of ABS.
As soon as the driver eases up on the brake pedal, normal brake
To exchange important data at
lightening speeds, the Mercedes-Benz brake assist system networks
with other in-car micro-computers for ABS brakes, ASR traction
control or ESP stability control, and the engine/transmission
The system even processes information
about the amount of brake wear and vehicle speed.
