Electronic Control Unit – A Look at Different Types Used in Motor Vehicles

An electronic control unit or ECU is usually linked to motor vehicles thus making it popular in automotive electronics. Some may often term it plainly as a control unit or other names such as control module. Generally, an ECU means a system of controls in order to test and analyze the electrical systems found in motor vehicles.

A unit is more of a general than a specific term. This simply means that it has other categories under its banner. With modern car owners, it is best to know the most common types of ECUs used by the automotive industry to make each motor vehicle serve its real purpose. The list includes engine control units, transmission control units and airbagl units.

Engine Applications

Sometimes, an engine control unit is also abbreviated as ECU. Specifically, this part of modern cars is used in order to control engines through employing techniques that will determine the amount of fuel that the motor vehicle has. It is also essential in controlling the timing and ignition of these engines through the use of sensors and basic reading values. Other functions of the engine include controls for idle speed and variable valve timings. Most modern cars already have programmable types and are highly significant when car owners want to modify the vehicle’s old engine.

Transmission Applications

This is another unit for motor vehicles that are critical in controlling automatic transmissions of modern electronics. It makes use of sensors of the vehicle and its corresponding engine control unit. The transmission control unit calculates when or how a person should change gears. This is important to make the shift quality better and to provide increased fuel economy. Both of these things are vital for the automobile to reach its optimum performance. Transmissions have changed from hydromechanical controls to a more updated version that has such controls. One of the most important changes in this type of ECU is the transmission solenoid.

Airbag Applications

Simply known as an airbag, this part of electronic cars is known as one of the passive safety devices. These are known as inactive counterparts of seatbelts. When used by vehicle owners, the airbag control unit becomes an active part of the vehicle as well.

Other types

Aside from the three main types of ECUs, there are others one must take note of. The list includes the telephone control unit, man machine interface, door and seat control units and the speed control unit. The enumeration for any vehicle will not be complete without the body control module which is essential in controlling door locks, windows and courtesy lights.

Automotive Electronics Plug You Into Safety

Every day, virtually everything around us becomes a little smarter and a little safer. In our age of information and technology, new digital and electronic components continually make our lives easier and safer at home, at work and on the road.

Some gadgets and gizmos, like nose hair trimmers, could easily disappear without much fuss. There are many intelligent tools, on the other hand, that make our lives more convenient and safer on a daily basis.

Our enormous world of “smart” technology is ruled by new automotive electronics. Anti-lock brakes, electronic stability control and other indispensable features are excellent examples of smart and safe automotive electronics.

Through recent developments within the automotive industry, there has been a huge increase in the number of electronic devices installed at assembly plants. Here’s an example of how quickly cars have evolved electronically: the Apollo 11 traveled to the moon and back again, using just 150 kilobytes of onboard memory. Today’s typical CD player, however, uses a whopping 500 kilobytes of memory just to keep our favorite songs from skipping. That uninterrupted music is an iota of how electronics impact a car’s performance to benefit drivers.

The term used to describe the technology involved in automobile communication systems is “Telematics”, and it was first used to describe the blending of telecommunications and “informatics”, or information technology. The telematics industry recently commanded an increased amount of attention from car manufacturers. Industry insiders predicted that telematics would become “the” go-to technology as early as the mid-1990s. Telematics was expected to increase overall sales and transform the automotive industry into a major player in mobile technology.

In reality, these optimistic forecasts panned out to be a little less than initially predicted. As more conservative measures came in to play, the initial industry projection of more than $40 billion dollars has been whittled nearly in half.

By no means do these numbers indicate an abandonment of the development of telematics technology. Automobile manufacturers have, in fact, invested an average of $2000 on electronic systems for every vehicle coming off the line. That’s a huge increase over the $110-per-car budget set in the early 1970s. The spending increase is reflected in everything from better engine performance and improved entertainment systems, to security features and safety devices. All of the electronic components work together to provide drivers with more comfortable, better performing and safer automobiles.

Here are some of the most common safe and smart automotive electronics systems:

CAN, or Controller Area Network

Your car doesn’t run on one computer; it operates with a network of computers. The Controller Area Network links all of the computers together. This type of system is similar to those used in home and business computers, known as Local Area Networks (LANs). The Controller Area Network in your car links the many separate computer systems together and allows them to communicate with each other. These interconnected systems incorporate critical systems like engine management, cruise control and anti-lock brakes with less demanding applications like seat controls and automatic windows.

Increased Fuel Efficiency

Shrinking resources and soaring fuel prices have forced automotive manufacturers to increase their supply of fuel-efficient vehicles. Smart auto makers are using new automotive electronics to create cars that burn fuel more efficiently. This is most evident with the common EFI, or electronic fuel injection system. Hybrid vehicles have taken this technology one step further, with electronic devices that allow drivers to switch automatically between gas and electric engines.

Trustworthy Safety Devices

There are two types of devices designed to protect the safety of the driver and passengers: active and passive devices.

* Active: These devices never stop working to ensure the safety of the driver and passengers. DSR (dynamic steering response), TCS (traction control) and ASR (acceleration slip regulation) are all examples of active safety devices. You may not notice these systems in operation, but they’re always working to create a safer ride. Active devices can sense the road and driving conditions and adjust your car’s performance accordingly. Researchers have credited ESC (electronic stability control) with reducing single vehicle skids.

* Passive: While more visible and seemingly simpler, passive devices are also controlled by smart and safe automotive electronics. Developments in electronics and technology have improved the deployment of airbags tremendously over the years. Airbags in early-model cars would deploy too soon or too late and provided little or no benefit to the driver and passengers. Now, cars have more advanced systems that can actually sense conditions that may lead to a high collision impact. Seating adjustment and airbag systems are automatically deployed to minimize the impact and decrease the degree of injury to driver and passengers.

When you consider the safety advancements that have been made in just a decade, you’ll agree that today’s cars are miles above their predecessors. Our automobiles provide so much more than a lift from point “A” to point “B”. With smart automotive electronics, every trip is as comfortable, secure and safe as possible.

Driving Conveniently With the Help of Smart Automotive Electronics

We live in the digital age where technology makes our lives easier each day. Advance medical equipments are created to help doctors treat patients, kitchen tools are innovated to make it easier for home makers, and cars are made smarter to make driving easier for humans.

Automotive electronics paved the way for helpful features like anti-lock braking systems (ABS) and automatic weather adjustments which makes driving safer and more comfortable.

Car manufacturers spend about two thousand dollars in automotive electronics for every car that comes out of the assembly line. These automotive electronics transform the car into a vehicle with better performing engine, more adaptive entertainment systems, and safety features that are far more superior than its predecessors.

Automotive Electronics of the Modern Car

o Control Area Network or CAN – There are several computers that run a modern car. The CAN is a network of computers that play vital roles in the different functions of the engine and its peripherals. The CAN serves as the bridge for the different computers so they can communicate with one another so everything are well coordinated. CAN controls the functions like cruise control, engine management, and the ABS.

o Fuel Efficiency- automotive electronics can save a car owner hundreds of dollars in fuel consumption. This is done through the EFI or Electronic Fuel Injection technology which ensures that the engine’s fuel consumption is at its optimal. In hybrid cars, a driver can easily switch from using gas and electronic power supply to run the vehicle.

o Safety Devices- Most safety system is controlled by automotive electronics. Devices like the Acceleration Slip Regulation, Traction Control, Electronic Stability and Dynamic Steering wheel ensure the safety of the driver and the passengers. The simple but complicated timing of airbags during a road collision is also controlled by advanced automotive systems.

o Added Features- Some cars today can even park themselves without any assistance from the driver. All the calculations are done by a computer making sure the car will not hit anything by making references to other cars and different objects in its surrounding.

One cannot imagine the evolution that took place with automotive electronics. The Apollo 11 which landed on the moon ran on a memory which is 150 kilobytes only. The sound systems of our cars today are running on 500 kilobytes of memory to ensuring our entertainment pleasure. Automotive electronics have gone far beyond entertainment and enhanced modern day vehicles in terms of safety, efficiency, and convenience.

The automotive industry projects billions of investments and sales in developing cars that are smarter, more fuel efficient and more environment-friendly in the future. Modern cars can be the answer to alleviate the adverse condition of the environment and the rising price of fuel all over the globe.

Cars are being developed to scan the traffic, the road, and all hazards so it can drive itself while the driver can do anything that he wants while in motion. The future cars can think for themselves with the aid of advanced automotive electronics. In that way, driving will be more than getting from one place to another.
