1. A computer-implemented method for alerting the presence of one or more combination vehicles, wherein each combination vehicle out of the one or more combination vehicles comprises a first vehicle unit and one or more second vehicle units, wherein the one or more combination vehicles is provided with a plurality of alerting units, and wherein 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 comprising:
obtaining movement data from at least one data communicating unit comprised in any one of the one or more combination vehicles, wherein the movement data is indicative of one or both of a current movement or an expected movement of the one or more combination vehicles,
based on the obtained movement data, determining at least one of the current movement and the expected movement of the one or more combination vehicles, and
when any one or both of the current movement and the expected movement is non-zero, and when at least one of the current movement and the expected movement of the one or more combination vehicles is less than at least one predetermined threshold, triggering a sound alert on the plurality of alerting units, comprising:
determining whether triggering the sound alert at a first sound volume is expected to fulfill a predetermined sound condition at an alerting distance from the one or more combination vehicles,
when the triggering of the sound alert at the first sound volume is expected to fulfil the sound condition, triggering the sound alert comprises triggering the sound alert at the first sound volume, and
when the triggering of the sound alert at the first sound volume is expected to not fulfil the sound condition, adapting the sound alert to obtain a first adapted sound alert expected to fulfil the sound condition,
wherein triggering the sound alert comprises triggering the first adapted sound alert.
