How many embedded systems are in a car

Embedded System is basically a system of hardware and software designed for control and access of data. As a system it includes a controller as the brain. Today embedded systems applications are popular and their development has become a boon to automobile industry. Applications in the form of home appliances, for automobiles, entertainments, consumer electronics, medical and telecommunication etc.

Embedded Systems in Automobiles - Current Trends. Mechanical systems in automobiles are largely replaced by electronic systems. Today Automobile industry is making great use of embedded systems. Ranging from wiper controls to complex anti-lock brake controls and air bags, embedded systems have gained the overall control of recent automobiles.

The automobiles that are built around using microcontrollers, digital signal processors or using both the processors are commonly called as Electronic Control Units. Today many BMW cars and luxury vehicles come up with large number of embedded controllers.

The first embedded system based automobiles Volkswagen came in the year Some of the current trends of embedded systems in automobiles include airbag controllers, navigation systems, satellite radio, adaptive cruise control, drive by wire, heads up displays etc. Anti-lock brake system is used in automobiles to avoid the vehicles from skidding especially in a slippery road. This system allows the wheels of the vehicle to have better contact with the road.

This system basically consists of sensors to track the speed, valves, pump and a controller. There is an electronic control unit in the system which monitors the movement of the wheel. If a wheel in the automobiles goes slow, the speed sensors will tell the valves to reduce pressure to the brake and thereby the wheel turns faster. On the other hand, if the wheel goes faster, the pressure to the wheel is increased thereby slowing down the wheel.

Satellite radio is a radio service broadcast from satellites to automobiles. It is available by subscription and it is commercial free. Navigation systems in automobiles are gaining wide popularity. These systems are made up with different functions that can help a common man. These systems get the signals coming from the satellites and allow knowing the position and direction of the vehicle.

This system basically consists of:. Hence, the driver of the car can set the speed of his respective vehicle and the distance between his car and other vehicles!

When the traffic slows down, it changes vehicle speed using moderate braking whenever required. Embedded Systems Used In Cars In automobile systems, much more equipment is being changed from mechanical to electronic systems. Embedded Airbag System This system helps to produce an important safety device. Richa K. Why Should We Study Robotics? Embedded Processor Vs Microcontroller.

Embedded rain-sensing system in automobiles is another automation system implemented with use of electronic system. 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 then 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. This automatic parking system is an independent car manipulation system that moves a car from traffic lane into a parking spot to perform the parallel parking, perpendicular parking and angle parking. This system mainly uses different methods to detect objects around the car.

Sensors installed on the front of the vehicle and rear bumpers acts as both a transmitter and a receiver. These sensors send a signal that will be replicated back when it meets an obstacle near the vehicle, and then the carputer will receives the time signal and bumper will use the radar to decide the position of the obstacle. The car will sense the parking space and distance from the side of the road then drive the car into the parking place. Please refer to this link to know more about FPGA.

Thus, the modern days embedded systems have marked a revolutionary change in every aspect of the automobile designing and manufacturing processes because of their adaptability and flexibility. Now the question is: Have you got the basic concept of embedded systems in automobiles? If you have got some basic understanding of this concept with a little bit of doubt on this topic, you can give your feedback and suggestions in the comment section below, and let us know how would you like to get some help or assistance from us.
