Data Flow Diagram From the Outside From the Inside
Functional Specs • Plug, cable and protocol and processor-to-protocol converter must conform to SAE standards • User input - 4 buttons providing the modes : • Read DTCs and Ams -- Erase codes • Save codes -- Retrieve saved codes • Processor - 68HC11 • Storage memory - 4 MB flash card • LCD display- 40 characters per line and ten lines, backlight • Enclosure – measurements: 4” X 3” X 2” It must be rugged and secure as to prevent damage to the inside, outside and plug
Scope • Only 1995 and newer cars and light trucks • Supports OBD II protocol only • Not a mechanics substitute • Not a common sense substitute • Not supercede owners manual
CS Subcontracts • CS 300U students will: • Research the future of auto technology. …improvements that are going to be in future cars and what major changes can result (paper or discussion forum) • CS 250 students will be providing the lookup and display software
Software Flow Chart Yellow = CS 250 Contracting
Evaluation Methods • Completion of the product prototype • See if the prototype can read the input from the car computers and output simplified DTC to the screen • Prioritizing and grouping DTC & getting user input & SAE input • The ultimate standard- if its well sold
Procedures • Having the engineer and programmers verify the correct functioning of the product • Competency of the marketing and advertising team
Potential Problems • Weather • Someone beats us to the market • Supplier/manufacturer/contractor slippage causes us to miss Christmas sales • Legal problems
Schedule and Tasks Oct 00 – Oct 01 LAUNCH 10/01
Resources Unless otherwise noted, resources are 100% KEY:
Milestones Functional Specs Complete Databases complete Prototype 1 complete Prototype 2 completed (stand-alone box) Final presentation to Customer First units manufactured Product sales launch
Deliverables • Preliminary project concept plan • Feasibility/ milestones/final presentation for customer • Product web site operational • Tables (AM and DTC) • Testing data • Prototype 1 (pc version) • Prototype 2 (box) • First units manufactured
Conclusion -addresses societal problems -can be built with current technology -will save the consumer stress/ money -will be profitable -will be ready in time for Christmas 2001
