Definitions

  • This object is achieved by mans of a method as initially mentioned, which comprises monitoring at least one component driven depending on the operation of the oil system, acquiring operational data for said component, and using the operational data and the estimated performance of the oil system to in order to provide an adaptive estimation of the operation of the oil system.
  • the second adaptive oil pressure model more or less continuously monitors changes of the VCT operation, and thus of the oil pressure. It is beneficial to isolate a certain repeatable moment of the VCT operation which is executed several times during a drive cycle, as the VCT operation may change due to the way the driver acts, and not due to the fact that the second adaptive oil pressure model needs to adapt to a change.
  • One possible such moment is the cleaning cycle of the VCT, since it then makes a sweep from the current position to an end position and back.
