Abstract
In today’s world vehicles form an important asset to us, without which our life would be incomplete. But, when it comes to the security
of our vehicles, we are very helpless. It is of a great concern, especially in metropolitan cities, where these incidents occur each and
every day. So, in this paper, I have focussed on the security of vehicles. The setup consists of a mix of software and hardware. In
software, I will be using an android application, and in hardware, a Raspberry pi board B+ model, a jaw or a gripper and other hardware
devices. This whole system will allow you to connect with your vehicle from anytime, anywhere and confirm it’s security. A vehicle is
usually the most expensive and important asset next to a home, so this system enables you to keep this asset at yo ur fingertips using
wireless technology. Think of it as a wireless leash to your car.

1. Introduction
Vehicle’s security is of utmost importance in today’s world. As
unemployment is increasing day by day, even the literate people
are involved in theft and robbery. So, the security of our vehicles
is the foremost requirement. The system which is designed,
ensures the security of our vehicle. It mainly uses two resources,
firstly, an android app and secondly, a device, which will be
installed in our vehicles. We would be able to control our vehicle
using the app. The functions made in the app will communicate
with the device in the vehicle, to control it . But, in order for this
system to work, our android phone and the device, should have an
internet connection. Thus, as we are using an internet connection
for communication, this system has an unlimited range, means we
can control our vehicle from any part of the world, as compared to
present days, where we use a key to connect to our vehicle from a
distance, but that has a limited range. With the help of this
system , we can connect to our vehicle from anywhere, anytime,
with a simple click on a button in the android app. Moreover, we
can discover our vehicle’s location, start it, stop it, lock/unlock the
doors, disable the use of our vehicle, monitor the alarm security
system and much more.
If a thief will try to steal our vehicle, we will be immediately
informed of it, through a text message, that someone is messing
with our vehicle. Then we can lock our vehicle with a simple click
on our smartphone, that means no one can move your vehicle after
that. Infact, the accelerator, gear and brake pedals will be locked,
so that the vehicle does not move from it’s position.
Thus with this system, theft of the vehicles can be prevented to a
greater extent, which is a very important asset to us and thus
leading to a safe society.
2. Background of the Study
A system is an assemble of related components making a whole
system. Security system is a system that gives an alarm when
someone tries to break into the vehicle. Earlier people were de-
pendant on simple ways of alert to breach in security. Approxi-
mate seventy percent of the vehicles today have a remote keyless
entry (RKE) system [12,15]. Most remote keyless systems alert
the vehicle against theft, lock and unlock the doors. Remote key-
less systems are made of a key fob transmitter and a receiver
which is installed inside the vehicle. These systems use a frequen-
cy of 315 MegaHz in the the U.S. and Japan, and 433.92 MegaHz
in Europe[6]. The challenges for the remote keyless entry designs
are achieving low power consumption in both RKE transmitter
and receiver, while achieving good range and reliability for the
RKE system[6,7,8,9].
Traditionally, the Security Systems were prone to thefts as they
were not very secure as in the work of Ji Shin[14] in 2009. Later
the enhancements in security of vehicles was introduced by Mon-
taser N. Ramadan, Mohammad A. Al-Khedher, Sharaf A. Al-
Khedher[2] in 2012. After that, significant improvements has been
made towards Security of Vehicles, notably by N. M. Z. Hashim,
M. H. A. Halim, H. Bakri, S. H. Husin, M. M. Said[16] in 2013
and Harish Chandra Mohanta, Rajat Kumar Mahapatra,
Jyotirmayee Muduli[7] in 2014. Further improvements were
noticed in the work of Shubhankar Shome, Rabindranath Bera[5]
in 2015 and Michal Czubenko, Zdzislaw, Kowalczuk, Andrew
Ordys[9] in 2015.

3. Technologies used
3.1 ADT(Android Developer Tools)
ADT is a plugin for eclipse[1] that has a set of tools integrated
with the eclipse IDE. ADT helps us to develop the android apps.
ADT has SDK tools and UI design tools for rapid prototyping,
designing and building your applications user’s interface. Applica-
tion is developed in JAVA programming language using Android
SDK[19,20].
Fig.1: Emulator for android app
3.2 Java
Java is a programming language developed by Jamer Gosling at
Sun Microsystems. The Syntax of Java is developed from C and
C++. Java apps are compiled to bytecode that can run on any java
virtual machine. It is the most popular language used today. We
have used Java programming language, so that our application is
secure, no one can easily hack it.
3.3 Python
Python is an open-source and a new programming language. It is
an interactive, interpreted and object-oriented programming lan-
guage. Python [16] has a very clear syntax. It has interfaces to
many system calls and libraries. It is extensible in C and C++.
Python is a portable language across all major hardware and soft-
ware platforms. We have used python to do coding on the GPIO
pins of the Raspberry pi board B+ model, as it is the best and easy
language to use with Raspberry pi board B+ model.
4. Hardware used
4.1 Raspberry pi Board B+ model
The Raspberry pi Board B+ model[3] is a debit card-sized single
board computer developed in the UK by Raspberry pi foundation.
It is a low cost computer that can be plugged into a computer
monitor or a TV and uses a keyboard and a mouse. It is a little
device that many people can use to explore computing and to learn
how to do programming in scratch and python. A very strong
feature of Raspberry pi board is it’s GPIO(general-purpose input-
output) pins , along the top-edge of the board. GPIO pins are the
input/output pins, and any of the GPIO pins can be designated(in
software) as an input or output pin, which can be used for a wide
range of purposes. In our system, raspberry pi board B+ model
forms a part of the device, which would be installed in the car.

4.2. A jaw or a gripper
A jaw or a gripper is a hardware which is used to grasp any object.
In our system, it will be fixed inside the car near the gear,
accelerator and the brake pedals at a particular angle, so that if a
thief tries to steal the car, then with the mere press of a button on
our phone, the gripper can be moved in forward direction, with the
help of motor(to which power is provided by the voltage generated
through the internet), to hold the gear, accelerator and brake
pedals in their position, so that the thief will not be able to move
our car.

4.3 Wi-fi Dongle
A Wi-fi Dongle is plugged into the Raspberry pi board. It will
allow us to connect to a wireless network anywhere.
Fig. 5: Wi-fi Dongle
4.4 Keyboard, Mouse and Adapter
We will be needing a keyboard, a mouse and an adapter that are
all connected to the Raspberry pi Board B+ model[6,10].
4.5 A Memory Card
A memory card will be inserted in the raspberry pi B+ model to
store the python coding done on Raspberry pi B+ board,.
4.6 Integrated Circuit(IC)
We have used L239D IC[15], to which all the motors are connect-
ed through jumpers(wires). And inputs from the raspberry pi board
are given to the IC and IC generates the corresponding output
function, which rotates the motors in clockwise and anti-clockwise
direction.

4.7 A step down transformer
A step down transformer [2] is used to step down the high voltage
to the normal bearable range i.e bearable to the device from AC
220V to AC 20V.
Fig. 8:A Step down transformer
4.8 Diodes
Four diodes are used on the board for the conversion of AC into
DC voltage. Diodes[10] are connected in such a way that part of
sine wave in the negative portion is made to occur on the positive
portion.
Fig. 9: Zener Diode
4.9 Capacitor
A Capacitor[1] forms a part in conversion of AC into DC voltage.
The sine wave formed by the diodes is passed through a capacitor,
rendering waves which do not touch the x-axis and they lie far
above the x-axis.
Fig. 10: Capacitor
4.10 Voltage Regulator
A Voltage regulator[1] regulates the voltage and step downs it
further to the nominal voltage bearable by the IC’s 1 V or 1.5 V.
Fig.11: Voltage regulator
4.11 A resistor
A resistor [2,3] is used to offer resistance to the current so that the
current remains in the bearable conditions and offers nominal
voltage to the IC.

5. The Working of the System
5.1 Overall description
First of all, we made an app using android developer tools. To use
the app, the user has to register on the app, and then he can login
into it’s account. After login, the user will find various options on
the application interface to control the various functions of the
vehicle and to lock the accelerator, gear and break pedals of the
vehicle, to ensure it’s security. Our main aim is to provide securi-
ty of the vehicle. It can be any vehicle, but in our case we are
taking, specifically a car.
Suppose, a thief tries to steal our car, and tamper with it, then
immediately a text message will be dropped on our phone, as well
in the app. As soon as we receive the text message, we can go to
the android application and click on the accelerator, gear and
brake buttons, given in the app.
As soon as we click on the buttons, the corresponding values will
be passed to the device installed in the car, through internet, and a
voltage of 3.3 V will be generated, which is received by the
Raspberry pi board. We have another board inside the device, on
which two IC’s are embedded. We have used L293D IC’s[3]. A
resistor, capacitor, voltage regulator and diodes are also embedded
on the board, whose functions are described in the section above.
A step down transformer is also connected to the board. The jaws
or grippers are connected to the IC’s, on the board.
The 3.3 voltage which is received by the GPIO pins of the
Raspberry pi board and the external voltage of the device, are then
fed to the board containig IC’s, through jumpers (wires). The
motive of making this board is to regulate the voltage and bring it
down to the nominal range bearable by the device, and to rotate
the motors in jaws or grippers, through IC’s, so that the jaws move
in the forward direction to hold the accelerator, gear, and brake
pedals in their position. The regulated voltage from the board
through the IC’s is now fed to the jaws or grippers, which have
motors inside them. The voltage will drive the motors and thus the
jaws would move forward and hold the acclereator, gear and brake
pedals in their position. We can also use additional motors to
control the functions of the car such as lock/unlock the doors etc.
The same motor can be rotated clockwise as well as anticlockwise
for example, for the opening of a door and closing of the door
respectively.
Thus even, if the thief is able to break into the car, then also he
will not be able to move the car. Then we can reach out to the
spot, as soon as possible, and catch the thief.
5.2 Description of the Device that will be installed in the
car.
The device that will be installed in the car contains a Raspberry pi
board B+ model and an another board containing the IC’s.
In order to simulate this system , we have used a Raspberry Pi
Board B+ model. In addition I have used a mouse, a keyboard, a
monitor and a wi-fi dongle. These can be connected to the ports of
raspberry pi board. A memory card is also inserted into it.
We have done python coding on the GPIO pins to provide various
functions of the car and for locking. When we click a button on
the app, a value is passed to the raspberry pi board, and a power of
3.3V is generated which is recieved by the GPIO input pins and
then this voltage is fed through the GPIO output pins to the board
containing the IC’s, which will regulate the voltage. This volatge
and the regulated external voltage of the device will move the
jaws or grippers in forward direction to hold the accelerator, gear
and brake pedals, in their position.

6. Conclusion
In this paper, we have made an android app, which is used to
communicate with the device installed in our vehicles, which in
turn will control the functions of the vehicle, as well as ensure the
the locking of the accelerator, gear and brake pedals, so that the
vehicle does not move. Thus, the most expensive and important
asset of all of us, will be on our fingertips and fully secure. This
will prove to be a great technique to prevent the theft of the
vehicles, especially in metropolitan cities, where theft cases are
being reported, everyday.
7. Future Work
In future, we are planning to install a GPS system[8,19] into the
device, with which the location of the vehicle can be instantly
located at any time remotely from anywhere. Furthermore, more
functionalities to automate the vehicle remotely from anytime
anywhere with the app are under process too. I am also planning
to increase the security of the vehicle by cutting off the battery
supply to the vehicle, thus adding to it’s security.
