Abstract

A method for positioning a crankshaft of an engine of a vehicle is to be implemented by a system that includes an Integrated Starter Generator, ISG, controller (21) and a main switch (20). The method is characterized by steps of: a) determining, after the main switch (20) is switched from a Key ON state to a Key OFF state where the ISG controller (21) is powered by an auxiliary power source, whether an engine speed is lower than a predetermined threshold for positioning the crankshaft; and b) performing, when it is determined that the engine speed is lower than the predetermined threshold, a crankshaft positioning process so that an angular position of the crankshaft does not correspond to a compression stroke of the engine while the crankshaft stops.
