This document describes a security feature for automobiles that is implemented using the CAN protocol. It discusses how modern vehicles contain many electronic control units connected via CAN networks to control various systems like engine management, entertainment, lighting, and more. The proposed system adds security features like vehicle theft prevention, location tracking if stolen, and automatic engine shut off in emergencies. It requires hardware like a PIC microcontroller, GSM and GPS modules, and software to design and code the system using tools like Proteus and MPLAB IDE. The system is intended to improve vehicle security and safety.

2. Today’s Automobiles come with digital control systems as there is constant growth in
technology.
Recent Vehicles contains large number of Electronic Control Systems and are in
large numbers of Electronic Control Units present.
The growth of automotive electronics is the result parties of the customers wish for
Better Safety
Greater Comfort
Improved Emission Control
Reduced Fuel Consumption
Introduction

4. Automotive industry uses Controller Area Network (CAN)as the in-vehicle network
for the
Engine Management,
Body electronics like door and roof control,
air conditioning
lighting
Entertainment(DVD, TV, FM radio) control.
Nowadays almost all car manufacturers have also started implementing CAN based
vehicle automation.CAN networks used in engine management to connect several
ECUs.
