Abstract

The present disclosure relates to a computer system (100) for a powertrain system (11) of a vehicle (10), the powertrain system comprising an internal combustion engine (12) connectable to one or more drive wheels (21), a transmission arrangement (17) arranged to be coupled to the internal combustion engine by means of a controllable clutch (14), the transmission arrangement having a gearbox (16) with a displaceable gear engaging device (30), the gear engaging device being displaceable between a gear wheel disengaging position and a gear wheel engaging position, wherein the computer system comprises processing circuitry (102) configured to selectively operate the powertrain system in a number of operational modes comprising at least an engine stop freewheeling mode (ES-FM), in which an output shaft of the engine is non-rotating, and the engine is disconnected from the one or more drive wheels, and wherein the processing circuitry is further configured to determine, during the engine stop freewheeling mode, that a position (31) of the gear engaging device is different from an expected position (32) of the gear engaging device for an engaged gear; and, in response to that the position of the gear engaging device is determined to be different from the expected position, determine to return the gear engaging device to the expected position.
