What Is Car ECU?
by Brian Garcia -
The motor vehicle computer system is an electronic control unit which used in modern auto motives to maneuver its electronic modules. Interpreting real time data from sensors and sending output to the different components, the auto motive main computer alter the appropriate maneuvering of the motor vehicle.
The engine control unit collect inputs from other components in the motor vehicle like the crankshaft and camshaft sensors to effectively compute information like intake, cooling system, consumption of fuel and a few other internal components to determind and maneuver the running working state of the engine, transmission system like the air bags, the fluid flow, the camshafts position etc.
A typical illustration is the speed detector found on the wheel which examine the car speed and send the information to the automotive main computer. With this model, instead of distributing signals to number of wires from one sensor, the signals is being transferred by the engine control unit to all the devices that use this information such as the suspension system, ABS, speedometer etc.
On-board Diagnostics Port
An automotive that employ automobile ECU will also provide On Board Diagnostics (OBD) provision to enable officials or driver to plug diagnostics equipment in order to inspect the automotive computer system state.
Motor vehicle computer system anti theft control
The engine immobilization computer is theft deter system placed on the automotive ECU. It forestalls the ignition from running unless driver is employing a commissioned key. This platform employs a special transponder chip key that saves the digital security code or simply the pass-code. The ECM wouldn't start up the injection system infrastructure and the ignition lock if the pin-code in the key is different then the pin-code stored in the immobilizer.
Different manufacturers of cars use several types of ECUs like the PCM (Powertrain Control Module), GEM (General Electric Module, BCM (Brake Control Module)) and others. Contemporary car may contain a few dosen ECUs and with this increasing complexity, the coding entailed in configuring or resetting the ECU is turning more challenging to maintain.
