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.
