• control arrangement 1 10 also comprises a transmitter 640, configured to transmit information to the other vehicles 102, 103.
• steps 501 -503 to be performed in the control arrangement 1 10 may be implemented through the one or more processors 630 within the control arrangement 1 10, together with computer program product for performing at least some of the functions of the steps 501 -503.
• a computer program product comprising instructions for performing the steps 501 -503 in the control arrangement 1 10 may perform the method 500 comprising at least some of the steps 501 -503 for initiating activation and/or deactivation of the engine of the vehicles 102, 103 within the group 100 when the computer program is loaded into the one or more processors 630 of the control arrangement 1 10.
• the described steps 501 -503 thus may be performed by a computer algorithm, a machine executable code, a non-transitory computer- readable medium, or a software instructions programmed into a suitable programmable logic such as the processor 630 in the control arrangement 1 10.
• the computer program product mentioned above may be provided for instance in the form of a data carrier carrying computer program code for performing at least some of the step 501 - 503 according to some embodiments when being loaded into the one or more processors 630 of the control arrangement 1 10.
• the data carrier may be, e.g., a hard disk, a CD ROM disc, a memory stick, an optical storage device, a magnetic storage device or any other appropriate medium such as a disk or tape that may hold machine readable data in a non-transitory manner.
• the computer program product may furthermore be provided as computer program code on a server and downloaded to the control arrangement 1 10 remotely, e.g., over an Internet or an intranet connection.
• the term “and/ or” comprises any and all combinations of one or more of the associated listed items.
• the term “or” as used herein, is to be interpreted as a mathematical OR, i.e., as an inclusive disjunction; not as a mathematical exclusive OR (XOR), unless expressly stated otherwise.
• the singular forms “a”, “an” and “the” are to be interpreted as “at least one”, thus also possibly comprising a plurality of entities of the same kind, unless expressly stated otherwise.
