INTRODUCTION

• Increased accident rate.

• Factors.

• Need of intelligent vehicles.

• Invention of Cruise control.

CRUISE CONTROL• Cruise control - automatically controls the speed of a

motor vehicle.

• Also known as Speed control or Auto cruise.

• Adjusting the throttle position to maintain a speed set

by the driver.

ADAPTIVE CRUISE CONTROL(ACC)

• Advanced version.

• Keeps steady speed.

• Uses sensors for detection.

• Keeps safe distance.

• Intelligent control.

• Collision avoidance system.

ACC COMPONENTS IN A CAR

WORKING OF ACC

• Switch on ACC.

• Set speed.

• Sensors detects vehicle ahead.

• Decelerate to ahead vehicle

speed.

• Keeps safe distance.

• Collision avoidance system.

ACCELARATION & DECELARATION

SENSOR OPTIONS • LIDAR is Light Detection And Ranging.

A laser diode was used to generate the light signal.

• RADAR is Radio Detection And Ranging.

It is operated by radiating energy into space and detecting the echo signal reflected from

target.

• FUSION SENSORS system was introduced by Fujitsu

Ten Ltd. and Honda.

It includes millimeter wave radar linked to a 640x480

pixel stereo camera with a 40 degree viewing angle.

FUTURE ASPECTS

• Co-Cooperative Adaptive cruise control or CACC is already being

tested in California .

• ACC respond to the distance and speed of the car ahead, CACC

communicate with two or more cars and work together to avoid

collision.

• Communication is quicker, reliable and responsive.

FEATURES•Maintains a safe, comfortable distance between

vehicles without driver interventions.

•Maintains a continuous performance during

road turns and elevation changes.

•Alerts drivers by way of automatic braking.

•It’s very useful for long driving.

•The driver is relieved from the task of careful

acceleration, deceleration and braking in

congested traffics.

•Reduction in accident rate. Reduction in driver

fatigue.

•Increased fuel efficiency.

ACC EQUIPED VEHICLES

•Ford fusion series.

•Jaguar.

•Mercedes Benz .

•Volkswagen.

•Audi.

•Chevrolet Cruse (India).

CONCLUSION

•Current system ranges 200 meters can stop and slows if any obstruction.

•Fully autonomous car is probably not viable in the foreseen future.

•Near by vehicles would be in constant communication with each other and

act co-operatively.

•It will probably take decades, but car accidents may eventually become

almost as rare as plane crashes are now.
