Method and control system for controlling movement of a group of road vehicles

The present disclosure relates to a method for controlling movement of a group (100) of road vehicles (101, 102, 103, 104, 105, 106). The group (100) comprises a lead vehicle and one or more additional vehicles. The lead vehicle comprises a first control unit (204) and a first communication means (206). The one or more additional vehicles each comprises a second control unit (214, ...2n4), which is adapted to in an at least partly automated mode have the movement of the one or more additional vehicle controlled by the first control unit (204) of the lead vehicle. The one or more additional vehicles each comprises a second communication means (216, ..., 2n6) for communication with the first communication means (206) of the lead vehicle. The vehicles of the group (100) are moveable relative to each other within the group (100) as regards longitudinal position, lateral position, speed and/or acceleration. The group (100) of road vehicles are controllable by the first control unit (204) of the lead vehicle so as to move as one body, a shape of the body being variable. The vehicles of the group thereby cooperate with each other. The disclosure further relates to a method for forming a group and to a control system (200) for controlling movement of a group (100) of road vehicles.
