INTRODUCTION

1.1 MOTIVATION

Driving is complex and challenging. A simple way to make driving safer is to reduce

the number of non-driving and distracting activities you undertake while driving.

Research shows that dialing and talking on a mobile phone while driving can lead to

Riskier decision making

Deciding when it is safe to turn in traffic is a complex task. Using a mobile phone

while driving affects judgment and concentration and you may fail to choose a

safe gap. When making a decision to turn across oncoming traffic, you also tend

not to consider the environmental conditions such as, when it is raining or the

roads are slippery. If you dont make safe turns you could crash.

Slower reactions

You generally react slower when using a mobile phone, particularly when youre

deep in conversation. You may take longer to respond to traffic signals or

completely miss them.

Slower and less controlled braking

During a mobile phone call your brake reaction time is slower, and you break

with more force and less control which results in shorter stopping distances

available between yourself and the car in front.

Wandering out of your lane

Youre more likely to wander out of your lane when youre using a mobile phone,

even on a straight road with little traffic.

Not being alert to your surroundings

When using a mobile phone, you tend to spend less time checking your mirrors

and whats going on around you. This affects your ability to monitor and

negotiate traffic safely.

1.2 PROBLEM DEFINITION

In the fast-paced society of today, we are focused on arriving at our destination as

quickly as possible. However, with this lifestyle, we are not always aware of all the

dangerous conditions that are experienced while operating an automobile. Factors such as

sudden vehicle maneuvers and hazardous road conditions, which often contribute to

accidents, are not always apparent to the person behind the wheel. In recent years, there has

been tremendous growth in smart phones embedded with numerous sensors such as

accelerometers, Global Positioning Systems (GPSs), magnetometers, multiple microphones,

and even cameras. The scope of sensor networks has expanded into many application

domains such as intelligent transportation systems that can provide users with new

functionalities previously unheard of Experimental automobiles in the past have included

certain sensors to record data preceding test crashes, After analysis, crash scenarios are

stored and analyzed with real-time driving data to potentially recognize a future crash and

actually prevent it. With more than 10 million car accidents reported in the United States

each year, car manufacturers have shifted their focus of a passive approach, e.g., airbags, seat

belts, and antilock brakes, to more active by adding features associated with advanced driver-

assistance systems (ADASs), e.g., lane departure warning system and collision avoidance

systems. However, vehicles manufactured with these sensors are hard to find in lower priced

economical vehicles as ADAS packages are not cheap add-ons. In addition, older vehicles

might only have passive safety features since manufacturers only recently began to introduce

an effective driver assist. Since sensors ultimately add onto the cost of a vehicle initially and

cannot be affordably upgraded, we target a mobile Smartphone as an alternative device for

ADASs that can assist the driver and compliment any existing active safety features. Given

its accessibility and portability, the Smartphone can bring a driver assist to any vehicle

without regard for on-vehicle communication system requirements.

1.3 OBJECTIVE OF THE PROJECT

In this chapter introduction of the SAFE DRIVING USINGMOBILE

PHONES are discussed. It gives overall view of the project design and the related

literature and the environment to be considered.

Chapter wise organization of the thesis and the appendices is given at the end of this

chapter. At first we discuss the main processing done using ARM7TDMI-S and then what is

the process that can be automated which is within the scope of the work. Then we discuss the

implementation aspects.

1.4 LIMITATION OF PROJECT

The driver has to place the mobile at the same place when he enters the car.

The driver has to lift the call manually.

In this we are not stopping the car we are just reducing the speed to the car to

10-20 rpm.

CHAPTER-2

LITERATURE SURVEY

2.1 EXISTING SYSTEM

Muting Mobile.

Voice Mail Converter

No information to caller

2.2 DISADVANTAGES OF EXISTING SYSTEM

Keep some data on existing points

2.3 PROPOSED SYSTEM

Automatic attend of the call.

Gives information about the Driver.

Only Emergency Call will connect to the User.

2.4 CONCLUSION

The former section consists of Ignition Starter; the microcontroller gives the

signal to the mobile.

When the signal is received by the mobile it immediately changes in to

Driving Mode.

In driving mode, if someone is calling it automatically attends the call and

gives response only for the emergency call.

SYSTEM ENVIRONMENT

3.1. INTRODUCTION

The flat form for this project is based on Embedded System. An Embedded system is

a special-purpose system in which the computer is completely encapsulated by the device it

controls. Unlike a general-purpose computer, such as a personal computer, an embedded

system performs one or a few pre-defined tasks, usually with very specific requirements.

Since the system is dedicated to specific tasks, design engineers can optimize it,

reducing the size and cost of the product. Embedded systems are often mass-produced, so the

cost savings may be multiplied by millions of items.

An embedded system is a special-purpose computer system designed to perform a

dedicated function. Unlike a general-purpose computer, such as a personal computer, an

embedded system performs one or a few pre-defined tasks, usually with very specific

requirements.

Since the system is dedicated to specific tasks, design engineers can optimize it,

reducing the size and cost of the product. Embedded system comprises of both hardware and

software. Embedded system is fast growing technology in various fields like industrial

automation, home appliances, automobiles, aeronautics etc.

Embedded technology is implemented to perform a specified task and the

programming is done using assembly language programming or embedded C. Ours being a

developing country the power consumption is increasing on large scale to meet the growing

need of the people. Power generation is widely based on the non-renewable sources and these

sources being depleting some means have to be found for power saving.

3.2. DESIGN OF EMBEDDED SYSTEMS

Intelligent, programmable and computing electronic device designed to perform

specific tasks based on a fixed time frame. An embedded system is a combination of

hardware and software, perhaps with some mechanical and other components designed to

perform a specific task.

Figure 3.1 Embedded System Design.

Electronics usually uses either a microprocessor or a microcontroller. Some large or

old systems use general-purpose mainframes computers or minicomputers.
