Security Feature for Automobiles Implemented using CAN protocol.

Under The Guidance Of K.R.Arun Kumar

ByK.Bhanuprakash,14MCE0061.

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

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.
