Abstract
The present invention relates to by a method, system, and computer program product for determining an uncontrolled behavior of an internal combustion engine of a vehicle due to unintentional combustion of fluid flowing between a crankcase and a cylinder space of said combustion engine. The method comprises the step of determining at least one vehicle related condition. The step of determining at least one vehicle related condition: determining whether a powertrain for said vehicle is in an engaged or a disengaged state; determining whether the engine speed is increasing; and determining whether said cylinder space is receiving fuel. The method further comprises the step of determining that an uncontrolled behavior is at hand if the conditions that: said powertrain is disengaged, the engine speed is increasing and said cylinder space is not receiving any fuel, are fulfilled.
