CE 2.2 Project Background
CE 2.2.1 Characteristics of the project
The main theory behind the working of this project is to implement the use of the braking
system of vehicles being developed in the recent market. I had worked on the project to
implement the proximity sensor of the cars with the braking system of the car. The implemented
system in the market it the sounding of an alarm system so as to make the driver aware of an
obstacle in front of the vehicle. I have worked on the project to implement a smart braking
system based on the proximity alarm system for the vehicles for an added security system. The
main aim of this project is to work on the process of developing an intelligent braking system
based on an electronically controlled vehicle braking system. I had compiled the working of the
project with the help of a sensor operated brake consisting of opto transmitter and receiver
controlling circuit and pneumatic braking system.

CE 2.2.2 Objectives developed for the project
For the completion of the project I had developed the following list of objectives which
had been followed:
 To make the project compatible with all type of sensor circuits of vehicles.
 To make the project with the help of network intelligence in the vehicle
 To accurately process the decelerating speed of the vehicle so as to reduce the collision
effect.
 To effectively understand the pressure and the temperature of the contact points of the
friction plate.
CE 2.2.3 My area of work
In this project I had worked for the process of helping my team mates with my skills as a
production engineer. I had looked after the working procedure of the project to see if the
complete project was working as per the requirements and the objectives which had been set
forward from the beginning of the project. I had also helped my team mates in the development
of the structural skeleton of the working of the vehicle. The project was to be made so as to look
like a model of an imitation of a vehicle.

CE 2.2.5 My responsibilities throughout the project
For the completion of the project I was responsible for the development of the skeleton
structure of the vehicle. We had attached all the materials and electrical components on the
skeleton to mimic the working of a vehicle. I had also guided my team mates with the help of my
production engineering skills. I had also looked after the completion of the project as per the
requirements and the objectives of the project.
CE 2.3 Distinctive Activity
CE 2.3.1 Comprehending the theory of the project
I had proposed an intelligent controlled braking system for a vehicle. I was able to
implement a neural network process for the understanding of the dynamic system as well as

working on the development of the braking system. Thus this project has been completed with
the help of the neural network process. The neural networks main objective was to provide the
project with a better control over the braking system. This helps in changing the brakes
performance under the influence of different factors as well as driver's performance. With such a
high task on the automatic braking system, the performance of the braking system should be
made into a best intelligent system.
CE 2.3.2 Engineering knowledge and skills applied in the project
For this project I had applied my skills as a production engineer. I had helped my team
mates with the best process to follow for the completion of the project as well as keep the cost of
the project in check so that the final project is feasible. The transmitter and receiver pair was able
to work seamlessly with the braking system of the project. I had used a compress air tank in
order to simulate the braking module of the project. I had taken care of studying the frictional
reaction between the brake plates and the wheel in order to slow down the vehicle and avoid
accident. The main objective was to make the project slow down the vehicle and not to bring the
vehicle at a sudden halt.
CE 2.3.3 Accomplishment and task performed
The project had been composed of 5 major parts which are to work in complete unison to
make the project successful. The five components are: opto transmitter and receiver pair, power
supply, solenoid valve, flow control valve and a compressed air tank. The transmitter transmits a
light ray and the receiver receives the light ray from the obstacles after getting reflected. Once
the receiver gets activated it notifies the circuit to start providing pressure on the brakes in order
to slow down the vehicle. Once the obstacle has been taken care of the air compressor expands
and the brakes are taken off the tyres.

CE 2.3.4 Identified issues and their solutions
2.3.4.1 Issues
During my time on the project i had faced many problems related to the connection of the
proximity sensor of the vehicle with the braking system. The system was not able to detect the
obstacles over a distance of 100 meters. The distance was becoming a major issue when the
vehicle is traveling at high speed.
2.3.4.2 Solutions
This problem was overcome with the help of making the proximity sensor calibrate to a
higher range of frequency for the detection time. Once the calibration was complete I was able to
make the vehicle detect the obstacles over a larger range of detection. The detection of the
obstacles from a larger distance would help in reducing a lot of accidents which occur due to
high speed.
CE 2.3.5 Plan to produce creative and innovative work
In the project I was able to implement the process of understanding the way a proximity
sensor works. This helped me to understand the exact way to use the proximity sensor and to
make the range larger than the distance it already detects. By understanding this I was able make
the proximity range more than the detectable range which helped in making the detection of
obstacles better in case of high speed of the vehicle. Apart from this I was able to make the
necessary arrangements inside the electrical panel of the project to take the consideration of the
temperature and the pressure to be applied on the wire so as to decelerate the vehicle rather than
to bring the car to a halt instantaneously. The project had been compiled on a skeleton frame to
mimic the use of a vehicle in real life situation.

CE 2.3.6 Collaborative work
For the completion of the project I had worked along with my team mates and my project
supervisor to deliver the best quality project abiding by the requirements as well as the objectives
for the project. Along with this collaboration I was able to receive help from the University
electrical laboratory for the process of testing the project as well as fixing the complete project
within the deadline. I had also conducted research on the topic to understand the process of the
working of the project. I had used the best process and guided my team mates accordingly for the
completion of the project within the deadline. I had used my skills in all aspects of the project to
make the project the best.
CE 2.4 Project Review
CE 2.4.1 Project Overview
At the end of the project it could be said that the project was successful in the following
the requirements of the project as well as the objectives which had been set forward at the initial
stage of the project. The project if implemented on a larger scale for the use in real life scenarios
would help stopping a lot of traffic accidents and to safeguard the pedestrians from harm. With
the help of the electrical equipment’s the complete project was able to work with the help of high
accuracy and the mechanical components helped in keeping the stability of the system. Even if
the driver of a car is less skilled, the intelligent braking system would be able to help in keeping
the driver safe.

CE 2.4.2 My contribution to work
For the completion of the project I had used my production engineer skills to guide my
project team mates through the working method of a project. I had worked on the process of
implementation of the project. I had provided the support for the project which was required for
the completion of the project as per the requirements of the project. I had also helped in the
designing and the making of the working structure of the project. It consisted of a working
skeleton structure with the other electronic components stuck on the frame to mimic the working
of a vehicle for the project.
