ABSTRACT

This is to show that the combinations of electronics with mechanical field can
create revolution in the field of automobiles and the way people travel. The ECU
( Electronic Control Unit ) is used to do many operations this is designed based on
the principles of the EMBEDDED SYSTEMS it gives intelligence to the vehicle
and it can be run with out any strain or confusion. The Safety and Comfort levels
are increased a lot. The vehicle equipped with this system can be called as smart
vehicles as they work depending on the situation. The probability of accidents is
very less hence safe.

ABS :-( Anti-Lock Braking System). This system protects the vehicle form getting
skidded at high speeds and also when there are sudden sharp bent turnings. There are
two sensors at each wheel one measures the speed of the wheel and the other
measures the turning and bending angles. These values are sent to the ECU where
these values are considered and signal is sent to the pumping motor present at each
wheel to correct the speed of the wheel.

FUEL INJECTION: - The process of sending fuel into the engine for
combustion and make the vehicle run is called FUEL INJECTION. This was done
using various mechanical techniques before but now considering the need of high
pick-up, mileage need for the vehicle electronic method are used. This brought in
lot of advancement in fuel injection. Presently we use MPFI (for petrol), CRDI
(for diesel) for injecting fuel. Using these methods we get better average, high
pick-up also the pollution is less.
