Embedded Systems Role in Automobiles with Applications
In today’s world, most electronic devices are based on Embedded Systems. Recently, In Automobiles also everything is used with the help of Embedded Systems only and all the mechanical systems in the Automobile has been completely replaced with the help of Embedded Devices. Nowadays, Automobiles making the complete use of Embedded System, where ever the Automobile system is depending purely on the Embedded Technology only. Ranging from Mp3 control to complex anti-lock brake control and Airbag systems controlling will be done by the
Embedded Systems in Automobile. Embedded systems have a huge variety of applications that vary from low to high-cost consumer electronics to industrial equipment, medical devices to weapon control systems, aerospace systems and entertainment devices to academic equipment, and so on. Embedded systems span all features of our present life. The applications of Embedded systems are shown below.
Telecommunication: Cellular phone, web camera, hub, router, IP Phone
Personal: Data organizer, iPhone, PDA, palmtop.
Today, a typical automobile on the road has computer controlled electronic systems, and the most
commonly used embedded systems in a vehicle includes,
Drive by wire
Adaptive cruise control
Anti-lock braking system
Tyre pressure monitor
In-vehicle entertainment system
Backup collision sensors
Heads up display
So, the automobile industry is completely replaced all the mechanical parts with the
Embedded Design. There is huge applications from embedded systems in Automobile and recently
trying to implement the Self driving system also it is very helpful to the physically handicapped
and Old age people.
For example, if you consider the Air bag system, it is an important safety device that provides an protection against accident. This system is works with the commands from the micro controller. If the sensors detects an accident, this micro controller operates the airbag system by operating alternator.
Embedded navigation systems, it is also an another advancement of the Embedded systems in automobiles in the navigational system using GPS system. This consist GPS receiver, a gyroscope, a DVD-ROM, map database, main controller and a display system. This will locate the live location of the vehicle and makes display the time estimated to the target place.
Satellite radio is an another application which provides radio service broadcast from satellites to automobiles. It is available by subscription and it is commercial free.
Adaptive cruise control is the another application, and it is useful to make driver less vehicle control in real-time by avoiding the accidents, this will be the better embedded products to be useful in the vehicles and this will allow the car to keep at the safe distance from the other vehicles. Each car has a laser transceiver or a microwave radar unit which is fixed in front of the car to find out the speed and distance of the any other vehicle in the pathway. This is works on the principle of Doppler Effect; it is nothing but change in frequency of the waves.
Embedded rain sensing system is the another application and this device will automatically detects the rain and it will automatically activates the windshield wiper. In this, an optical sensor is placed on small area of the front windshield glass (opposite to rear-view mirror). This optical sensor is placed at an angle to emit the infrared light which reads amount of light by it when the light is reflected back. This light is reflected in cases where the windshield is wet or dirty. Thus the optical sensor determines necessary speed and frequency of windshield wiper depends on reflected light into the sensor.
Drive by wire is an another application, where this system helps to replace the mechanical systems in automobiles with electronic systems using actuators and HMI(Human Machine interfaces) Components of the automobiles like belts, steering column, pumps, coolers, vacuum servos and master cylinders, hoses, intermediate shafts are eliminated.
Here, some of the major industries that help to develop these current trends in automobile industry
1. Atmel: Provides different controllers like ARM, 8051 Most of the body electronics, security, safety and automotive products are manufactured by them.
2. Texas Instruments: They provide different controllers, automotive control chips and DSPs to automobile industry.
3. Xilinx: Provides different CPLDs, FPGAs, and other application related cores for development of navigation systems, adaptive cruise control etc.
Silicon Providers, NxP, Analog devices, NEC, Renesas etc. are some other automobile industry. Now-a-days, there is huge openings on embedded systems with automobiles and every automobiles companies are replacing the embedded systems. So if any one want to growth your carrier in embedded Automobile so please join in good embedded System training institute. There is a top embedded training institute in Bangalore to provide the complete embedded system course. So, please join good embedded training institute and we are the Professional Training institute in Bangalore, we will provide you complete the Embedded system course in Automobiles.
