The effective wheelbase (30) of the vehicle unit (100) is a distance between a first position (10c) of a first coupling point or a first axle group (1) of the vehicle unit (100), to a second position (20c) of a second axle group (2) of the vehicle unit (100). The processing circuitry (902) is configured to obtain multiple candidate estimations of the effective wheelbase (30). The multiple candidate estimations have been estimated using different estimation models. The processing circuitry (902) is configured to estimate the effective wheelbase (30) based on the multiple candidate estimations.

The invention relates to an internal latch (44) for internally latching a door (22) of a vehicle (10) with respect to a cabin abutment member (38) of the vehicle, comprising: - a base (50) which is configured for attachment to an internal side of the door (22); - a clasp assembly (52) comprising a clasp (54), where the clasp (54) exhibits, with respect to the base (50), a storage position and a latching position, and where the clasp assembly (52) is attached to the base (50) by a deployment linkage (56) allowing the clasp assembly (52) to deploy from a retracted position, when the clasp (54) is in the storage position, to a deployed position, when the clasp (54) is in the latching position, according to a deployment movement; wherein the base (50), the clasp assembly (52) and the deployment linkage (56) form an articulated polygon.

A flywheel arrangement (1) for an engine (5) of a vehicle (3), comprising:- a flywheel configured to be connected to a crankshaft of the engine for common rotation around a center axis,- at least one pendulum weight arranged between the center axis and a radially peripheral surface of the flywheel, the at least one pendulum weight being movable with respect to the flywheel along a predetermined pendulum path,- a ring member positioned radially outside of the at least one pendulum weight, the ring member being connected for common rotation with the flywheel around the center axis,- at least one pair of cooperating bearing surfaces, each pair of cooperating bearing surfaces comprising an outer bearing surface provided on the ring member and an inner bearing surface provided on the at least one pendulum weight, the at least one pair of cooperating bearing surfaces together defining the predetermined pendulum path.

A vehicle includes an imaging system including a first camera and a second camera in a housing mounted to the vehicle, and a processing circuit that uses a first calibration information obtained from a calibration of the first camera to generate a second calibration information to calibrate the second camera. The first calibration information identifies a first position difference between a position of the first camera and a reference position, and also identifies a first orientation difference between an orientation of the first camera and a reference orientation. The second calibration information includes a second position difference between the second camera and the reference position, and a second orientation difference between the second camera and the reference orientation. Generating the second calibration information includes combining the first calibration information with translation information providing a position difference and an orientation difference between the first camera and the second camera.

A computer system (1000) comprising processing circuitry (1002) configured to determine whether a combination vehicle (1) is unstable is provided. The combination vehicle (1) comprises a tractor (10) and a plurality of trailers (12). The plurality of trailers (12) comprises a first trailer (11). The processing circuitry (1002) is configured to obtain vehicle condition signals indicative of a status of the combination vehicle (1). The processing circuitry (1002) is configured to obtain relative positions of the first trailer (11), relative to the tractor (10). The processing circuitry (1002) is configured to, estimate a motion (m1, m2) of the plurality of trailers (12). based on the relative positions of the first trailer (11) and the status of the combination vehicle (1).The processing circuitry (1002) is configured to, determine whether or not the combination vehicle (1) is unstable based on the estimated motion (m1, m2) of the plurality of trailers (12).

The invention relates to a computer-implemented method performed for alerting the presence of one or more combination vehicles. Each combination vehicle out of the one or more combination vehicles comprises a first vehicle unit and one or more second vehicle units. The one or more combination vehicles is provided with a plurality of alerting units. Each respective first vehicle unit and respective one or more second vehicle units comprises a respective alerting unit out of the plurality of alerting units. The method comprises obtaining (301) movement data from at least one data communicating unit comprised in any one of the one or more combination vehicles. The movement data is indicative of one or both of a current movement or an expected movement of the one or more combination vehicles. The method further comprises, based on the obtained movement data, determining the current movement and/or the expected movement of the one or more combination vehicles. The method further comprises, when any one or both of the current movement and the expected movement is non-zero, and when any one or both of the current movement and the expected movement of the one or more combination vehicles is/are less than at least one predetermined threshold, triggering a sound alert on the plurality of alerting units.
