Abstract—Brake assist is one of the safety system which use in recent cars. It is one of the active system which helps to
save the cars from the collision. Brake assist works in an emergency situation when the driver press brake pedal with
insufficient force. In such case car does not at sufficient distance which leads to accident. In that case brake assist
system determines that situation and it increases brake boost so that car stop at sufficient distance. Brake assist system is
installed after the no of test & great amount of research has been carried out. Brake assist system has been shows that it
reduces the stopping distance by a significant margin. It decreases the stopping distance up to the 20%. Both the
percentages of severe accident involving pedestrians as well as the rate of rear end collision are for lower for the vehicles
equipped with BAS than the vehicles without BAS.
INTRODUCTION
This history of automobile starts from the invention of I.C engines but real invention was started in 1886 when
the first automobile plant was started by Mercedes Benz. During those days the automobile was not technically
advanced, a motor carriage which could carry two or more person was the definition of automobile .As time
changed the automobile became more & more technologically advanced and its possession became a „status
symbol‟ in society. Earlier while purchasing a car customer think only cost & comfort, but now the people started
concentrating on the safety of the car i.e. how safe the car /as the human life is more valuable than anything else.
The modern day cars like Mercedes Benz, BMW, Rolls Royce, etc. are coming with a number of safety devices
which try to save the human life in case of accident or an emergency. Brake assist is one of the safety system
which use in recent cars. It is one of the active system which helps to save the cars from the collision. Brake
assist works in an emergency situation when the driver press brake pedal with insufficient force. In such case car

Assist as the standard equipment on all its models.
Arrangement / Purpose / Design function of BAS control module
Location:
Under the tandem master brake cylinder or integrated in the ESP control BAS control module
Purpose:
Performs all the BAS brake control functions. Supplies the instrument cluster with the signal for the BAS,
BAS/ETS,
Performs all the BAS brake control functions. Supplies the instrument cluster with the signal for the BAS,
BAS/ETS, BAS/ASR or BAS/ESP is malfunction indicator lamps.
Function of BAS control module:
The BAS control module is divided up functionally as follows:
i. Signal Processing.
ii. Logic section.
iii. Safety circuit.
iv.Signal Processing:
The following i/p signals are conditioned for the logic section:
1. Two speed sensors at front (from traction system control module via CAN; ABS, EPS)
2. Stop lamp switch (from traction system control module via CAN: ABS, ETS, ASR)
3. Vehicle identification system (vehicle model & engine via CAN from the respective engine control module)
4. BAS diaphragm travel sensor
5. BAS release switch.
