Gone are the days of carburettors and mechanical injection with the fuelling process now electronically controlled via an EMS (Engine Management System). Increasing emissions standards and customer requirements for more efficient/reliable vehicles has driven the need for most processes within the vehicle to be accurately controlled via electronic control units (ECU).
Modern vehicles are fitted with an array of sensors that are connected to in most cases multiple control units. It is not uncommon to have 5 or more control units which each have specific tasks around the following: engine, transmission, body, braking, stability, cabin/climate and dash cluster. All of these ECUs are connected together on a “data bus” to allow them to exchange information between each other.
We know that decisions are best made when all information is at hand, improving accuracy of the decision usually requires more information.
The hardware Imarda installs into the vehicle to provide tracking information can also be linked into the vehicles “data bus” allowing it to listen to the information that is exchanged between the ECUs. We use this information to compile reports and generate alerts which are sent back to Imarda’s servers allowing further historical and trend analysis.
