What Is Car ECU?

by What is car ECU The vehicle computer system is an electric computer which used in modern cars to maneuver its electric modules. Interpreting real time data from sensors and transmitting output to the different module, the vehicle computer system alter the appropriate functioning of the auto motive.

The ECU gather inputs from the different components in the vehicle like the crankshaft and camshaft sensors to effectively compute information such as exhaust, intake, fuel injection and several other components to evaluate and maneuver the driving state of the engine, transmission system such as the fluid flow, the ignition/injection timing, the traction control (ABS) and others.

A common example is the wheel speed detector which calculate the wheel speed and transfer the information to the ECU. Using this infrastructure, rather than handing out messages to number of modules from one sensor, the messages is being distributed by the engine control module to all the components that need this information like the suspension system, speedometer, ABS and others.

On-board Diagnostics Port

OBD port An automotive that incorporate ECU will also offer On-board Diagnostics (OBD) interface to enable driver or officials to connect diagnostic equipage if you need to retrieve and display the auto motive main computer condition.

Vehicle computer system theft deter control

The car immobilization system is theft opposing infrastructure partition in the automotive's computer. It forestalls the ignition from starting unless employing an authorized key. This system uses an exclusive transponder key that saves the digital security pin-code or plainly the pass-code. The ECM will not power on the combustible system infrastructure and the ignition cylinder if the PIN code in the key is not in sync with the PIN code kept in the immobilizer.

Different car manufacturers use several types of ECUs including the BCM (Brake Control Module), PCM (Powertrain Control Module), GEM (General Electric Module) and others. Latest auto motive may contain many ECUs and due to their growing complexity, the coding involved in configuring or resetting the engine control module is becoming much more difficult to operate.
