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

ECE 415 Senior Design Project Fall 2009
• 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

User Control

ECE 415 Senior Design Project Fall 2009
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.

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
