A method for a combustion engine (200) of a vehicle is presented. The combustion engine comprises: - a first group (225a) of two or more cylinders (220a-d) connected to a first exhaust gas manifold (240a) comprising a first pressure sensor (241a); and - a second group (225b) of two or more cylinders connected to a second exhaust gas manifold (240b) comprising a second pressure sensor (241b). The following steps being performed by a control unit (500) when the combustion engine is out of normal operation: - controlling the combustion engine (200) to run at a plurality of different engine speeds ω<1> , ω<2>, ... , ω<n>; - inducing, for each of the plurality of different engine speeds ω<1>, ω<2>, ..., ω<n>, at least one fuel cutoff for at least one (220a) of the four or more cylinders during a time interval T; - measuring at least one first P<resp_a> and second P<resp_b> misfire pressure responses with the first and second pressure sensors; - determining at least one misfire template T<misfire_a>, T<misfire_b> based on the at least one first and second misfire pressure responses.

An electric motor (1) comprising a rotor (2) rotatably arranged about a central axis (A) of the electric motor (1) and a stator (3) coaxial with the rotor (2). The stator (3) comprises a stator core (4) having a radially outer surface (10) comprising a plurality of ribs (8, 8') distributed circumferentially and extending longitudinally between axial ends (4a, 4b) of the stator core (4). The electric motor (1) further comprises a housing (12) arranged radially outside the stator (3) such that a substantially annular gap (14) is formed between the outer surface (10) of the stator core (4) and an inner wall of the housing (12). Moreover, the electric motor (1) comprises a cooling system (20) configured to create a circumferential flow (F) of a cooling liquid in the substantially annular gap (14). A vehicle (100) comprising the electric motor (1) is also disclosed.

The present disclosure relates to methods for operating an articulated vehicle (1) comprising a pulling vehicle (1a) and a trailer (1b). The pulling vehicle (1a) comprises one or more sensors (11) arranged to monitor an environment of the articulated vehicle (1). The method comprises detecting (S2), in the monitored environment, an occluded region (3) in a neighbouring driving lane (4b), wherein the occluded region (3) is occluded by the trailer (1b) from a field of view of the one or more sensors (11). The method further comprises controlling (S3) the articulated vehicle (1) in its present driving lane (4a) in a view phase (VP) in which the pulling vehicle (1a) is steered towards the neighbouring lane (4b) to thereby momentarily removing the trailer (1b) from the field of view in the neighbouring lane (4b) of the one or more sensors (11). The disclosure also relates to a corresponding control arrangement and computer program, and to a vehicle comprising the control arrangement.

The disclosure concerns a gear shifting arrangement (8) for a gearbox. The arrangement (8) comprises a rotatable barrel cam (52) with a first track (60) and a shifting shaft (26) connected to the gearbox (14) and provided with a track follower (56) to follow along the first track (60). The first track (60) comprises a first inclined portion (601) configured to cause a first partial movement (PM1) of the shifting shaft (26) in a first axial direction (A1) from a neutral position (NP) to a first intermediate position (IP1) as the track follower (56) follows along the first inclined portion (601). A displacement mechanism (70) is configured to be activated at the first intermediate position (IP1) to cause a second partial movement (PM2) of the shifting shaft (26) in the first axial direction (A1) to a first gear engaging position (GP1).
