CLASSIC COMFORT<br />
“Merging the past with the present”<br />
Testing<br />
Testing will be performed throughout the timeline of this project to ensure success. Each<br />
individual component will be tested at various levels. Desktop testing of individual component will be<br />
done in order to ensure that each component operates properly. There will then be a breadboard test<br />
for the overall system to insure that our device performs to specifications. Finally there will be a<br />
prototype test which will ensure the entire functionally of the device. This will allow us the opportunity<br />
to make sure our Classic Comfort product works according to our requirements.<br />
All impedance components will be tested in order to ensure proper voltage drop. Amplifiers will<br />
be tested to ensure proper operation. The signal conditioning circuit will be tested to ensure they<br />
convert the voltages and currents properly as well as protect the microcontroller.<br />
Software will be tested to ensure it performs to specifications; it will be tested for robustness,<br />
extensibility, fault-tolerance, and ease of maintenance. The software must be able to perform under low<br />
resources and also allow for future modifications without having to change the entire software system<br />
design. It must be able to recover from errors and have the ability to also be reset by the user. This<br />
system must be easy to maintenance as well as update.<br />
We will also stress test the entire system making sure that all of the separate components can<br />
work at the same time without destroying our prototype. Overall our system must perform optimally in<br />
the expected conditions of an everyday car.<br />
Fabrication<br />
Fabrication will be performed after each of the prototype PCBs are created. Once each board is<br />
populated, we will test the hardware and software on each of the boards according to the test plan. We<br />
will also need to create an enclosure for our device to assist in keeping hazardous objects outside of our<br />
device. The enclosure will include a place for a dual seven segment display, three buttons for user<br />
control, a place for incoming and outgoing cables to connect to the wiring harness, and a reset button to<br />
default the device to its factory default settings.<br />
Documentation<br />
Our documentation will cover two major areas, the final technical report and the user’s manual.<br />
The final technical report will consist of all major information that Painless will want from us as well as<br />
all technical documentation that will cover our costs, parts list, major troubles we incurred, etc. The final<br />
technical report will include the final set of schematics that will detail how the Classic Comfort device<br />
was designed. It will also include the final source code that show the exact code used in programming<br />
the PIC18F microcontroller. The report will also include the final PCB layout of our board mapping out<br />
each individual component which was used. Our test plan and the results from the final testing will be<br />
documented as well in our final technical report. In the user’s manual we will include information for the<br />
user so they will know how to install the classic comfort device. It will also include information on how<br />
to properly utilize the three button user interface in order to change each individual setting.<br />
