Abstract
(EN)
A method for controlling an operation of an internal combustion engine comprising a crankshaft, the method comprising: obtaining reference data corresponding to at least one reference rotation speed of the crankshaft, the reference data being associated with at least one reference characteristic of an operation of the engine; obtaining operation data corresponding to a rotation speed of the crankshaft; determining a measure of a similarity between the reference data and the operation data; estimating at least one operation characteristic of the operation of the engine, based on the determining; and triggering an action associated with the operation of the engine, based on the estimating.
