Background
• 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
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

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
