Method and device to provide adaptive oil priming functionality

A method and a device for operating a pre-lubrication system for an internal combustion engine of a hybrid electrical vehicle after vehicle start up, wherein the hybrid electrical vehicle comprises an electric engine and the internal combustion engine. The electric engine is turned on at vehicle start up and the internal combustion engine is turned on at vehicle start up or after a period of time after vehicle start up. The pre-lubrication system comprises an engine control function for controlling the internal combustion engine, monitoring the torque requested by a driver and storing information regarding when the driver requests torque equal to or higher than a predetermined torque threshold. The cranking operation of the internal combustion engine, in order to build up oil pressure and fill the oil circuit with oil, is initiated based on the stored information or when the electrical hybrid vehicle reaches a predetermined vehicle speed threshold.
