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.

2. CONCEPT OF ACTIVE SAFETY

• Initially let’s see “Passive Safety Devices” are:

• On the contrary Active Devices are:

3. NEED OF ACTIVE SAFETY SYSTEM

• Adverse trends for passive systems.• Human error factor not accounted in passive

systems.

4. VARIOUS ACTIVE SAFETY SYSTEMS

A. Near Object Detection Systems

B. Run Off Road Warning Systems

C. Adaptive Cruise Control Systems

D. Collision Warning/Avoidance Systems

E. Driver Monitoring/ Warning Systems

F. Automated Highways and Co-operative Intersections

G. Night Vision Enhancements Systems

H. Pedestrian Safety Systems

I. Call for Help

5. VARIOUS COMPONENTS OF ACTIVE SAFETY SYSTEMS

A. Airbags

B. Seat Belts

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.

E. Sensors

• Proximity sensors• Weight Sensors• Overhead Sensors• Rollover Sensors

6. DISADVANTAGES

• Costly• Complex• Mass produce• Minor glitches in the software.

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.

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”
