What Is Car ECU?


What Is Car ECU? by - What is car ECU The automotive ECU is an electronic control unit which used in modernised automobiles to control its electric components. Interpreting real time data from sensors and delivering output to the different module, the vehicle ECU manage the appropriate operation of the automobile.

The ECM gather information from the different digital units in the auto such as the crankshaft and camshaft sensors to smartly compute data as intake, exhaust, injection fuel system and some other components to assest and control the driving state of the engine, transmission system as the body functions, the traction control (ABS), the ignition/injection timing and others.

A common example is the wheel speed detector which examine the speed of the wheel and transfer the data to the auto motive's computer. With this model, rather than sending messages to multiple wires from one sensor, the messages would be sent by the engine control module to all the components that makes use of this data as the suspension system, ABS, speedometer and others.
