3. 1. INTRODUCTION
• The beginning of the 20th century heralded the advent
of the motor vehicle era.
• During the last decade, with the ability of making use
of materials like silicon in semiconductors, the
electronics industry has seen a kind of a revolution.
• Active safety systems make the most of these
relatively recent developments.

4. 2. CONCEPT OF ACTIVE SAFETY
• Initially let‟s see “Passive Safety Devices” are:
• On the contrary Active Devices are:

5. 3. NEED OF ACTIVE SAFETY SYSTEM
• Adverse trends for passive systems.
• Human error factor not accounted in passive
systems.

6. 4. VARIOUS ACTIVE SAFETY SYSTEMS
A. Near Object Detection
Systems
B. Run Off Road Warning
Systems

7. C. Adaptive Cruise Control
Systems
D. Collision
Warning/Avoidance
Systems

8. E. Driver Monitoring/
Warning Systems
F. Automated Highways and
Co-operative Intersections

9. G. Night Vision Enhancements Systems
H. Pedestrian Safety Systems
I. Call for Help

10. 5. VARIOUS COMPONENTS OF
ACTIVE SAFETY SYSTEMS
A. Airbags
B. Seat Belts

11. C. ABS (Anti-Lock Braking system)
If the wheels lock during braking, the brakes on that
wheel are momentarily released to maintain the
traction on the road.
D. ASR (Acceleration Skid Control)
ASR controls the torque supplied to that wheel.

12. E. Sensors
• Proximity sensors
• Weight Sensors
• Overhead Sensors
• Rollover Sensors

13. 6. DISADVANTAGES
• Costly
• Complex
• Mass produce
• Minor glitches in the software.

14. 7. FUTURE TRENDS
• The increasing role computers are taking in today‟s
vehicles‟ safety, with luxury cars having as many as
60 microprocessors.
• Striking examples of this are the Mitsubishi HSR-6
prototype and the Volvo XC90 SUV.

15. 8. CONCLUSION
• Need of the hour.
• But all this finally boils down to „ONESELF‟. There
is no alternative to „ALERT AND SAFE DRIVING‟.
• The gist of the entire discussion is:-
“FATE MAY SAVE YOU ONCE, SAFETY WILL
ALWAYS”
