PLAN OF PRESENTATION• ACCIDENTS BACKGROUND !• WHY BRAKING IS REQUIRED ?• WHY AEB REQIURED IN VEHICLES ?• HOW THE BRAKING IS APPLIED ?• AEB PARTS• AEB WORKING• AEB TYPES• ADVANTAGES• DISADVANTAGES• CONCLUSION

World Health Organization, road traffic injuries caused an estimated 1.25 million deaths worldwide in the year 2010.

India occupies 1st Position in ASIA.

In India, due to road accidents 1,37,000 have been killed in 2013 and 1,39,671 in 2014 and it is increasing on an average by 5% every year.

For every hour 16 deaths have been recorded and 382 deaths for every day.

Andhra Pradesh ranked the fifth highest in the total number of road accidents (43,482) with a share of 8.9 percent in the country.

ACCIDENT BACKGROUND

TYPE OF COLLISION

• HEAD ON COLLISION:-

• REAR END COLLISION:-

• SIDE COLLISION:-

WHY BRAKING IS REQUIRED ?TO STOP A VEHICLE OR SLOW DOWN A

VEHICLE

WHY AEB REQIURED IN VEHICLES ?

AUTOMATIC EMERGENCY BRAKING IS A TECHNOLOGY FOR AUTOMOBILES TO SENSE AND AVOID AN IMMINENT COLLISION WITH ANOTHER VEHICLE, PERSON OR

OBSTACLE BY BRAKING WITHOUT ANY DRIVER INPUT

HOW THE BRAKING IS APPLIED ?

AUTOMATIC EMERGENCY BRAKING PARTS

• SENSOR• RADAR• CAMERA• ECU

SENSOR:TACTILE SENSORI R SENSOR

RADARACC(ADAPTIVE

CURSIE CONTOL)

CAMERA• 200 METERS• CLEAR VIEW OF

CAPTURING• STEREO IMAGE CAMERA

HOW THE AEB BRAKING IS APPLIED ?

AEB WORKING TYPES• FORWARD COLLISION WARNING OR REAR END COLLISION• COLLISION MITIGATION BRAKING SYSTEM• COLLISION AVOIDANCE

FORWARD COLLISION WARNING OR REAR END COLLISION

FIRST STAGE –PREDICTIVE BRAKING ASSISTSECOND STAGE – PREDICTIVE COLLISION WARNING

THIRD STAGE- BRAKE APPLIED PRESSURE

COLLISION MITIGATION BRAKING SYSTEM

COLLISION AVOIDANCE

THE MAIN AIM IS TO REDUCED THE ACCIDENTS TO PEDESTRAINS IS UNDER RESEARCH $DEVELOPMENT

FCW

• AUDI Q7• BOSCH• TOYOTA PRIUS• CHRYSLER 200.• NISSAN TAMURA• FORD TAURUS.• VOLKSWAGEN GOLF

SPORTWAGEN.• NISSAN ALTIMA.

CMBS

• CHRYSLER 300• MERCEDS BENZ S CLASS 2006• HONDA CIVIC• LEXUS LS SALOON• HINO MOTORS• MAZDA MAZDA6 • NISSAN SENTRA• VOLVO• VOLKSWAGEN GOLF

ADVANTAGES• CRASHES CAN BE REDUCED• IT ALLOWS THE DIRVER TO MAINTAIN THE DIRECTIONAL STABILITY

AND CONTROL OVER STEERING DURING BRAKING

DISADVANTAGES• DRIVER SHOULD KNOW THE FULL SOFTWARE ABOUT THIS WORKING• IT CANNOT BE FITTED DURING ASSEMBLY• COST IS MORE• IT TAKE OUT THE TOTAL CONTROL OF THE VECHICLE

APPLICATIONS• GOOGLE DRIVER LESS CAR

• LOAD TRUCKS

CONCLUSION• WHERE DO WE NEED TO BE TO ACHIEVE A 50% REDUCTION IN DEATHS AND

INJURY BY 2020?• AUTOMATIC BRAKING SYSTEMS CAN STOP THE CAR TO AVOID AN ACCIDENT.• OVERALL, IT WAS FOUND THAT AEBS IS HIGHLY LIKELY TO BE A VERY EFFECTIVE SAFETY MEASURE

ANY QUERIES ?
