ECU / VCS

IntroductionAn ECU is a micro computer that reads information collected by sensors distributed on the vehicle and uses that information in real conviction to ad notwithstanding different processes that are happening in the gondola car, lot the driver and the engine to have better efficiency.

The control of car and race car engines is becoming increasingly more multifactorial with more rigid emission/higher performance standards and invariable effort to gain higher fuel efficiency. Twenty eld ago, control systems were mechanical (i.e., carburettor, distributor, and breaker contact). Now, microcontroller-based systems control fuel barb and ignition. Since the control strategy for anengine expects strongly on the current operate point (e.g., revolutions, momentum, etc.), linear control models, (e.g., PID) are not sui give in. On the other hand, non mathematical models describing the complete behaviourof an engine exists. Most engine controllers use a look-up table to represent the control strategy. The table isgenerated, from the results of extensive testing and engineer?s experience. The times of much(prenominal) a look-uptable, however, is only suitable for three dimensions (two inputs and one output). Also, the generation and interpretation of such tables is difficult and considered a black art.

dissever AFunction of production car ECU / VCSThe ECU is one of the most important separate in a car, is considered the brain of the vehicle.

Today the production vehicles locoweed almost think, the ECU can analyse the data received by the sensors, and act on it. From the fuel injection, to the ignition timing expiry trough the immobilizer, engine speed, throttle position or just the simple lights that gives you information on the dash board, they are all told activated by the ?brain? and also will depend in which sensors the car have. The complexity of the ECU will depend on the car that we?re talking about, obviously if we buy a low...
