Mobile Operating Vehicle Electronics

ECE 415 Senior Design Project Fall 2009

Preliminary Design Review

Background

• Current Vehicle Remotes– Security

• Alerts• Sensors

– Climate Control– Range– Price

2

Grenzebach Glier & Associates, Inc.

2


• Problems with current remote systems– Range is only up to 1 mile most of them use

900MHz RF– Security

• The device doesn’t use alerts systems• Sensors are not used to its fullest capabilities

– Climate Control doesn’t have the desired temperature feature

– Price for this Viper 5900 SST remote is $599.99

Mobile Operating Vehicle Electronics (M.O.V.E)

• Communicate via WiFi/cellular network• Provides up-to-date car alerts, increased

security, and peace of mind• Ability to get into a car and go• Other convenience related to cars controls

The Solution

System Deliverables• Car communication via web interface

Each user will be able to log on to accounts specific to their vehicle

• Up-to-date car alertsGain access to current car information

• Many functional applicationsUser account give users the ability to perform various functions

Deliverables

User Interface• The web application will be easy-to-use• Will incorporate icons that perform desired

tasks• Personal settings for alerts• Front end transmitting portal• Displays users completed task

Deliverables

Initial User Manual1. Log into your account2. Recover information from the car3. Performed desired tasks4. Tasks are completed

Acceptance Test• As long as the vehicle is in Umass Wi-Fi range

M.O.V.E. will be able to perform its task

User Control

11


11


The user will be able to communicate with his vehicle

over the wireless internet network.• At the user control end, we will create an encrypted

web interface (unique and customizable for each user)

• Would require the user to log-in to access and control the features of his vehicle.

• Webpage would be password secured and use https for secure communication.

Car Control

• The car control consists of a Controller Area Network (CAN-bus) which is a computer network protocol and bus standard designed to allow microcontrollers and other devices to communicate with each other without a host computer.

12


12


Car Control

• A modern automobile has around 50 electronic control units (ECU or nodes) for various subsystems.

• CAN provides a serial bus standard for connecting ECUs.

• Each node is able to send and receive messages; a message is transmitted serially onto the bus, one bit after another.

• Every node requires a host-processor, a CAN Controller and Transceiver
