ABSTRACT: In this paper we introduce a real time operating system for the vehicle which improves vehicle safety
and provides various automation facilities for the vehicle. An MSP430 microcontroller is used as the core controller in
the smart vehicle so as to achieve a real-time operation system (OS). This controller works as the control system to
operate the entire vehicle. The real-time controller enhances the performance of control and simplifies the design and
management of software. In addition, this system uses speed control, automated breaking and horn blower along with
an automatic air conditioning system. The utilization of high-precision of ultrasonic sensors on obstacle avoidance
robot provides a guarantee for safety

I. INTRODUCTION
Over the years various technologies were developed for improving the safety and automated facilities inside a
car. But most of them were highly expensive and were not affordable by majority of the population. The efficiency of
the developed system was also an issue. Most of them were not satisfying the promises made by them. Various
automobile manufacturing companies have tried and developed number of systems on various processors, but the result
was not satisfactory in overall and was also not cost effective.
At the moment there are lot of vehicles which are coming with various driver assistance facilities such as seat
belt warning, door ajar warning, electronically adjustable ORVM’s, obstacle detection, parking sensor, automated
transmission, voice triggered engine etc. But most of them are not of major concerns and when them come in a
package, they will cost us much.
II. MOTIVATION
Even though there are lots of advancements in the field of automobile technology, it is hard to find a package
which make the driver comfort and feel safe at low cost .When it comes to satisfaction, it is difficult point out a vehicle
which is comfortable, safe and at the same time affordable.
III. RELATED METHOD
At present different companies use different kind of processors such as ATMEGA,PIC controller, ARM 7 etc.These
processors are mainly used for some specific applications and hence become complex when is used for multi processes.
Other major concerns include cost of production, power consumption, complexity in design and the difficulties in
interfacing and implementation.
Even though various companies are providing higher security measures such as voice control systems they are highly
expensive and are not affordable by a majority of the population.82% of the car owners in India uses low end cars
which are priced bottom in the market, which points out the fact that all most 80% of the users are not used these kind
of facilitations and assistance which in fact reduces the overall comfort and even keeps their life in danger due to the
lack safety measures

IV. OUR APPROACH
We propose an advanced method for car security and automation using MSP430 microcontroller which is ultra
low power consuming, cheap and highly compact. This paper aims at developing an ultra low power consuming and
affordable assistance system for vehicles which ensures safety and various features like automatic speed control and
breaking, automatic horn blower, voice recognition system, obstacle detection system and temperature sensitive air
conditioning system.

Fig1: Architecture of MSP430
The methodology of this project design can be divided into two sections; hardware and software
implementations. The hardware implementation consists of the development of the main controller, sensor network and
the smart automation network. On the other hand the software implementation focuses on the programming of the
microcontroller using IAR Embedded Workbench.
V. MODULE 1
Module 1 deals with an ultrasonic obstacle avoidance system. It includes an ultrasonic transmitter and receiver
circuit and a Signal Control Unit. Ultrasonic transmitter continuously emits ultrasonic radiations. Similarly the receiver
end is used for collecting the reflected radiations from the obstacles if any.
The sensor circuit is connected to a Signal Control Unit (SCU), which act as a comparator circuit. Here the
comparator circuit continuously compares the time differences between the transmitted and received signals. From the
time difference the output voltage of the processor also varies from which the distance of the obstacle will be
calculated.

VI. MODULE 2
In this module an automated breaking system is used along with obstacle detection module. Here
the obstacle will be detected at a distance as in the module 1; as a result the vehicle will be stopped at a closer point by
the application of break gradually. The break will be applied from a point at which the obstacle is detected. Here a
DAC is used for converting the digital signals from the processor in to analog signals.
Fig5: Speed control circuit
Here a control circuit is deployed which will be interfaced with the fuel injector in the vehicle. When the output of the
MSP430 processor is high, the control circuit will regulate fuel injector valve in such a way that speed of the vehicle
goes on decreasing thus stopping the vehicle at the maximum voltage value.
Module 2 also includes an automatic horn blower system which is associated with the module
1.Here when the vehicle detects an obstacle it will automatically start blowing Horn, in order to make the other vehicles
and pedestrians aware about the vehicle .Here the output of the processor is connected to a driver circuit which will
trigger the horn. The driver circuit is used for switching the horn ON and OFF during presence and absents of an
obstacle.

VII. MODULE 3
A temperature driven automated air conditioning system is the main function involved in the module 3. Here the
temperature inside the vehicle will be detected by a temperature sensor and according to the temperature values the AC
will be turned ON or OFF and also its cooling effect will be controlled.
Fig6: Automatic air conditioning system
Here the temperature values will be processed by the MSP430 and will be displayed in the LCD display. Now the
output of the MSP430 will be send to the AC through a driver circuit and a relay. The driver circuit is used to drive the
relay. The purpose of relay is to switch the load i.e. here the Air Conditioner. Climate of the AC can be varied using a
TRIAC.
VIII. CONCLUSION
In this paper, we propose an advanced method for vehicle safety and automation using MSP430 microcontroller
which is ultra low power consuming, cheap and highly compact. Microcontroller act as the brain of the entire system
which includes an automated air conditioning system, ultrasonic obstacle avoidance module and an automatic speed
control system, automatic breaking system and an automatic sound blower, which in overall ensures safety for the
passage from direct collisions and also comfort the driver with various assistance systems that makes the drive more
effort less. The system that has been proposed in this paper has also compensated the drawbacks present in the existing
systems and is highly cost effective and low power consuming than the existing systems.
