Embedded system

• An embedded system is a system containing a number of simple hardware parts that are fed with a code (generally called as embedded programming language).

• Thus a set of instructions is passed to the hardware on how to operate according to the operator need.

Embedded systems in automobiles

Real time applications Applications

Automation feature

Road to vehicle communication

Vehicle to vehicle communication

How is Automation Achieved?

• An automated system uses– Some devices as its eyes and ears– Some devices as its brain to process the

data collected through those eyes and ears

– Some devices as its arms to perform actions

sensors Controller (microprocessor)

actuators

Achieving automationSensors :• Some of the sensor systems used areGps,speed sensor,skidding sensor,Sensors to detect an unlocked belt.Actuarors :• They are those devices which take

control of brakes when skidding is sensed.

• Device which injects fuel to the engine.

Road to vehicle communication

• Sensors sense the prdestrians and the vehicles movments and warns the driver in the car accordingly,if he wants to take a turn

Adaptive cruise control• Vehicles use the

RADAR system for collecting the information about its surroundings.

• It thus automatically manages its speed

How will all Microconrollers achieve a good communication through out the

system ?

EMBEDDED BUS LINE

Embedded bus lineController area network (CAN)CAN or Controller Area Network or CAN-bus is an ISO standard computer network protocol and bus standard, designed for microcontrollers and devices to communicate with each other without a host computer

Conclusion :• Thus Embedded systems fruits give

comfort to the user through its applications,but it doesn’t mean that human intelligence should be kept off completely.
