Automation of car using embedded system
[attachment=16278]
What is Embedded System
Imbibing intelligence into devices
Combination of hardware and software
Programmed to perform functions with minimal operator intervention
Several applications such as computing data communications, telecommunications, industrial control and entertainment sector.
Introduction to Automation of Cars
Preventing danger in the best possible way by incorporating intelligence into cars
Interfacing microcontrollers with basic structures of steering, braking and accelerating systems
Actions required are taken only if the driver is not able to steer the car out of danger even after the driver is alerted
Proposed system can be implanted in a manually driven car at a very low cost
Description of the System
Consists of transducers, microcontrollers, multiplexers plus the braking, steering and the acceleration systems of the car
The ultrasound transmitters on each side of the car are fired with a voltage pulse simultaneously
The clock program fed to each of the peripheral microcontrollers (MCf, MCre, MCl, MCr) is started
The ultrasound transducer closest to the obstacle will be the first to generate a voltage pulse that passes through the AND gate and stops the clock
