IntroductionIn each year

15000 traffic accident

200 people are killed and 20000 people injured Cost HKSAR about 30 million dollars

- 95% accident is due by driver error

OthersCar errorDriver error

Introduction

- What kinds of driver errors ?

SituationMost problem are

too close and wrong turn

How to solve it ?

Cooperative Adaptive Cruise Control System

TooClose

WrongTurn

Too Fast

Others

Cooperative Adaptive Cruise Control System Two or more vehicles

to communicate and work together to avoid a collision.

Transmitting information about its speed and acceleration to the car behind it.

3 Main Components

1.1. Radar Based SystemRadar Based System -Report on the width,

distance , and speed of objects ahead .

2.2. Headway Control UnitHeadway Control Unit- Control the Brake, Throttle , Dashboard display.

3.3. Image-ProcessorImage-Processor- Combines the data, feeding it to the headway control unit that controls the car

Basic theory

The Cars communicate with one another by exchanging radio signals.

It will then work out a safe following distance on the basis of their actual performance characteristics.
