How Do Our Car Computers Work
March 28th, 2012 . by amster88Modern cars have come very far since that were first seen jugging through towns and cities. Whereas previously there would have been no electronic components in cars, electronics these days is part of each system maintains a functioning car, the headlights to the engine of the radio.
Before the beginning of the 1970s, car engines were purely mechanical, with simple designs and methods for controlling the operation of the engine. At this point the concepts of fuel efficiency and emissions were basically, while that the main factors of performance and improvement of speed and power. However, by age 70 restrictions began to appear as people realized that it was not simply about the manufacture of more powerful cars, which became particularly evident by fuel shortages widespread in the United States. Automotive technology changed slowly, and by the early 1980s the first integrated circuit and Electronics began to surface. Fast forward to today and we have cars with fuel injection of precision controlled by computer, navigation, controls temperature and climate systems, computers that regulate manual and automatic transmissions making millions of calculations per second, and of course, a wide range of entertainment and communication systems.
In the heart of the modern electronic car is motor, engine or ECU control unit control module. The ECU has no control over all motor actuators that are designed to change the parameters of the internal engine, to ensure that it works with optimum efficiency. This efficiency means that the car must never use any more fuel needs, which also helps to perform under certain conditions of fuel economy. The ECU performs this task through the use of the information sent to it from an array of different sensors, such as fuel, coolant sensors sensors and oxygen sensors and interprets these data using search tables. If the computer is that something has to change to make the engine more efficient, sends the singles to motor actuators, adjusting them accordingly.
For example, the ECU is able to control with precision the rate of sparks inside the Chamber of combustion for improved efficiency and power, and the opening and closing of the valves of the engine to optimize the air flow into the engine. For motoring enthusiasts that have changed his car to include things such as turbochargers or new intercoolers, there is a special form of ECU, known as a programmable ECU, whose operation can be programmed by the user to adjust and optimize the modifications. Many new supply of programming and reprogramming and more retailers offer a range of control units for all major car manufacturers.
Won’t be long before Electronics is really the last word in engineering and design of the car, and with cars already come out with hybrid engines, automatic braking and even automatic, the possibility of driving fully automatic parking is closer to that much.
