Slide 1:CARSCellular Automotive Remote System Abhishek Jain
Slide 2:Objective Effectively work in a group to produce a working prototype of a cellular automotive remote system.
At expo the demonstration system will send and receive information via a cellular phone.
Slide 3:Functionality Resembles OnStar
More universal, many more and different convenience features.
Through CARS the user can control:
Heat and cooling system
Slide 4:Functionality CARS obtains and sends information about:
Slide 5:Optional Features User obtains information via voice messages
Control movement of vehicle (prototype)
Gives information of vehicle distance from user
Information received from car on a terminal
PC or microcontroller
Slide 6:C.A.R.S.- System Overview
Slide 7:Functionality OverviewVehicle-based system
Slide 8:Functionality Overview“Home”-based system
Slide 9:Preliminary Board Layout
Slide 10:Preliminary Board Layout(And Mechanical Design of OPTIONAL Mobile Platform)
Slide 11:Tone Reception and Decoding
Slide 13:Solenoid Control Principle of Operation:
A digital signal is used to control the driver circuit.
Driver circuit consists of discrete components or an IC. Current spikes and other large, inductive load concerns must be analyzed.
Solenoid only needs to be energized for a fraction of a second in order to push the appropriate button. Overall power use should be relatively small.

Matt Lasek/Nguyen Le-Inputs (excluding audio features)
Mike Charogoff –Audio Input/Output
Blair Harness-Programming, Micro-controller
Slide 18:Risks and Contingency Plans Areas of risk:
Learning hardware/software use of micro controller
Shouldn’t be an issue, several group members are familiar with technology
Ability to push (and possibly hold for speed dial) buttons
Number of buttons we will need to push
Plan on using solenoids for pushing buttons
Multiple fixed solenoids vs single solenoid on servo drive
Audio quality needed for tone recognition
Shouldn’t be a problem
Add filters/amplification if needed
Slide 19:Risks and Contingency Plans Areas of risk:
Voice reply (optional)
Strings of digits sent back – requires ‘base station’ module
If possible, add voice reply
Time vs quality considerations
Number of messages needed
Accident alert thresholds
Should not report accident under hi-performance vehicle acceleration
Will need thresholds
Might have to setup differently for different cars
Slide 21:Summary CARS convenience features include:
Remote start/idle system
Heat/Cool the interior of your car
Lock/Unlock your car doors
Accident Alarm System
