AIRBAG SYSTEM FOR 2-WHEELER VEHICLE SYSTEM

2. Topics to be covered
 Introduction.
 Design with Required Instruments.
 Technical Features
 Fitting Cage
 Angle Measurement Instrument
 Airbag Protection Mechanism
 Conclusion.
 References.

3. Introduction
 Nowadays the increment in the death rate of India is 20%
because of the accidents on the highways hence this invention
can help us to reduce the death rate by 7% to 10% since this can
be used in the pedestrian and safety department.
 In 4 wheeler vehicle the operations is based on the collision of
two vehicles or collision with any object.
 This system is installed in dashboard and the battery power is
consumed for working of this system.
 Over the last 50 years, the number of passenger cars has
multiplied.
 As roads have become increasingly busy, the number of traffic
accidents has also increased dramatically.

4. Graph >>> Accidents occurs yearly in Germany

5. AIRBAG SYSTEM FOR 2-WHEELER VEHICLE
 This new system which can help to severity of injuries caused
by frontal collision is to be made available on the new gold
Wing motorcycle .
 In the 2-wheeler system there is installation of the airbag
system in between and at both sides of the bike.
 There is usage of the battery of bike for working of system.
 There are two cases when system runs by both the angle
difference calculation and collision of the 2 bikes or by the
any accident of bike with any object.

6. Parts of Air Bag System
1) Air bag (leather material with grip technology)
2) Chemical cylinders for releasing the air or gas
3) Sensors (angle sensor and crash sensor)
4) Fitting cage
5) Angle measurement instrument (angle indicator)
6) Battery used (bike battery)

7. Modification For The Airbag Container

8. TECHNICAL FEATURES OF SENSOR(1)
 Giant Magneto Resistance (GMR)-based principle
 Integrated magnetic field sensing for angle
measurement
 Full calibrated 0 - 360° angle measurement with
revolution counter and angle speed measurement
 Two separate highly accurate single bit SD-ADC
 15 bit representation of absolute angle value on the
output (resolution of 0.01°)
 16 bit representation of sine / cosine values on the
interface
 Max. 1.0° angle error over lifetime and temperature
with activated auto-calibration

9. TECHNICAL FEATURES OF SENSOR(2)
 Bi-directional SSC Interface up to 8Mbit/s
 Supports SIL with diagnostic functions and status
information
 Interfaces: SSC, PWM, Incremental Interface (IIF), Hall
Switch Mode (HSM), Short PWM Code (SPC)
 0.25 μm CMOS technology
 Automotive qualified: -40°C to 150°C (Junction
Temperature)
 ESD > 4kV (HBM)
 RoHS compliant (Pb-free package)

10. ANGLE MEASUREMENT INSTRUMENT
(ANGLE INDICATOR)
1) When the proximity sensor is active then it will measure the
angle between road surface and the tires of the bike.
2) This angle is displayed on the angle indicator which is fitted near
the speedometer on the handle.
3) This indicator will give signal about the degrees in which the bike
will turn/tilt.
4) When the angle is less than 30 degrees to the right or to the left
side, then the air bag will open.

11. Airbag Open In Right Side Of Bike Due To Exceeds
The Angle Less Than 30 Degree

12. Airbag open in both directions when any object
Collapse to the motorcycle

13. BODILY HARMS OCCUR IN THE ACCIDENT:
1) Hand/leg Cracks or fractures
2) Head injury
3) Bleeding from body parts
4) Getting thrown from bike

14. CONFIGURATION OF IMPACT OF MOTORCYCLE TO CAR

15. HOW AIR BAG SYSTEM PROTECTS THE HUMAN BODY
PARTS:
 The air bag system opens from the bottom to the left or right side of bike;
hence we can avoid hand/leg cracks or fractures. The diameter of the air
bag when opened is more than height of the bike and that of the rider,
hence head injury is avoided.
 As the material used in the air bag construction is light weight strong
leather the chances of bike skidding or slipping is diminished and external
injuries like scratches are avoided.
 The chances of the rider being thrown from the bike are avoided as the
leather belts are provided on both sides of the bike to secure the legs of
the rider.
 The material used for constructing these belts is similar to those used for
constructing the seat belts in the cars.

16. CONCLUSION
 By providing the total safety to the motorcycle rider by implanting
the airbags in both sides of the motorcycle as mention in this
paper we will reduce the fatality rate by 20% to 30%.
 By using this technology there is not only reduce the death rate
but also we gives the total protection to the rider as well as
motorcycle.
 The experimental research will show the how this system is useful
and it may be published as soon as possible.
