Introduction

• Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications.

• microcontroller act as a microcomputer without any digital part.

microcontrollers

History The Smithsonian Institution credits TI engineers Gary

Boone and Michael Cochran with the successful creation of the first microcontroller in 1971.

The result of their work was the TMS 1000, which became commercially available in 1974.

Structure of microcontroller • Cpu :

All microcontrollers have a Central Processing Unit (or CPU) and this is responsible for taking the data, processing it and spitting out a result.

• Memory : PIC Microcontrollers have three types of memory 1.Programe memory 2.Data memory 3.EEPROM memory

Microcontroller in Automobile

Figure – Microcontroller implementation growth in the automobile

A radar speed gun (also radar gun and speed gun) is a device used to measure the speed of moving objects. It used in professional spectator sport, for things such as the measurement of bowling speeds in cricket,.

Speed checker :Most of the cases main reasons of accident on highway is overspeed and to prevent this types of accidents speed checker sensors.

GPS based Vehicle tracking system :Car tracking using GPS project will be useful when our car is stolen. Also if somebody wants to track school bus of their children, at that time it will be helpful to find out the location of kids.

Coolant Temperature Sensor

• The coolant temperature sensor is used to measure the temperature of the engine coolant of an internalcombustin engine.

• On some vehicles the sensor may also be used to switch on the electric cooling fan.

PD1 Rear Parking SensorWhen reverse gear is engaged the parking sensor system provides an instant, automatic, self-diagnostic function that maps out the surrounding area of your bumper constantly monitoring this as you reverse with 100% accuracy.

PDI Parking Sensor

LAMBORGHINI Parking Sensor

• PD1 Rear Lamborghini parking sensor PD1 Rear Lamborghini parking sensor provides your car with full rear bumper protection when parking and reversing, alerting you to approaching objects via an audible speaker.• PD1 front Lamborghini parking sensor PD1 Front Lamborghini parking sensor provides your car with full front bumper protection when parking, alerting you to approaching objects via an audible speaker.

Alcohol Detection • “Drunk driving detection• Alcohol Detector in Car project is designed for the

safety of the people seating inside the car. Alcohol breath analyzer project should be fitted / installed inside the vehicle.

Ambulance Tracking System This project performs three main functions. First one is Patient health monitoring; second one is tracking the Ambulance which is carrying the Patient and third one is to send above two details to the Hospital or Doctor using a GSM technology.

Advantages

Microcontroller reduce cost and size of the system. Usage of microcontroller is simple , easy for troubleshoot

and system maintaining. Microcontroller are cheap and very small in size , therefor

they can be embedded on any device.

Disadvantages Microcontroller have got more complex

architecture than that of microprocessor. Only perform limited number of execution

simultaneously. Mostly used in micro-equipment. Cannot interface high power devices directly.

Application

Vehicle Control 16 bit microcontrollers are  mostly used Driver Information 8- Bit microcontrollers are used mostly

Conclusion

Therefore, the modern days different types of microcontrollers have marked a revolutionary change in every aspect of the automobile designing and manufacturing processes because of their adaptability and flexibility.
