INTRODUCTION
today Personal Computer usage has been
increased very much for different purposes and for
performing important tasks and its usage is
increasing day by day in many fields.
The technique presented here has three parts,
each part containing some tasks to perform through the
computer. First part includes controlling the car through
computer by using data pins of parallel port. Second
part includes hurdle detection through sensor and
displays this information from left, right, front and back
side of the vehicle on the computer screen. The third
and last part is implementation in which the vehicle
moves automatically and selects its right path with the
help of sensors.
PREVIOUS WORK
Today many companies work to create the safe
environment (Hurdle detection and distance measuring)
for drivers, out of which the most important companies
working on these issues are Mercedes Benz and
Honda. Mercedes Benz [2] is prepared with the option
of innovative ‘distronic’ distance control system which
makes sure the security of cruise control for highway by
reducing the vehicle speed if the system detects a
slower running vehicle up to 150 meters in front of it. The
Mercedes is installed with a radar sensor which senses
the hurdle at a distance of 150 meters from the driver’s
car and slows down the car according to the distance
which means that as the distance decreases, the speed
of car is also decreased. These sensors observe the
traffic with a high performance computer so that the
safety distance remains maintained.
PROPOSED WORK
The proposed method for safe environment
includes three main parts, each one providing different
functionality according to the tasks assigned to it. These
parts are mentioned below:-
1. Distance of object (Hurdle) from vehicle.
2. Speed of coming object (Hurdle).
3. Location (Side) of hurdle.
4. Collision time (Future Planning)
In the proposed technique the user can easily
drive the vehicle through computer. The proposed
method will automatically inform about the hurdle in the
path of the vehicle on the computer with the help of
different sensors. In this technique the vehicle is
controlled through parallel ports of computer. Ultrasonic
sensors are connected in the vehicle to sense the object
(Hurdle) and send signals to the computer. The
computer takes different actions based on these signals
in order to create a safe environment for the driver
(user).
EXPERIMENTAL RESULT
In this section, experimental results are
illustrated to demonstrate the feasibility and validity of
our proposed hurdle detection and distance measuring
mechanism through ultrasonic rays. In this section
different situations (environments) and conditions are
applied upon proposed method. Actually the only way
that researcher can establish cause-and-effect
relationship through research is by carrying out an
experiment. In a formal experiment, the relationship
between two or more variables is investigated by
deliberately producing a change in one variable in a
salutation and observing the effects of that change on
other aspects of the situation.
Several steps are involved in carrying out an
experiment, but the process typically begins with the
development of one or more hypotheses for the
experiment to test.
