Have you ever wondered why modern cars always seem to run smoothly in all driving conditions?
Modern vehicles are controlled by many sophisticated on board computers more commonly known in the industry as Electronic Control Modules (ECMs) or Elcetronic Control Units (ECUs). In fact some cars have over 20 different control units that are constantly reading, exchanging and manipulating data between themselves. When a module senses a problem with an electronic command, it will often override the issue by altering the parameters of the pre-programed data without “advising” you through lights on the dash.
ECUs make these improvement processes automatically and in real time. In a closed-loop system, different sensors accumulate data from the network and send data to actuators that provide the interventions required to achieve the best outcome for the driving conditions and service item condition it has to deal with. The output of sensors tell the system what the car is doing and the contribution of new inputs back to these sensors from the ECU make the critical amendments.
