DETAILED DESCRIPTION Hereinafter the term “link” refers to a communication link which may be a physical connector, such as an optoelectronic communication wire, or a nonphysical connector such as a wireless connection, for example a radio or microwave link.
Hereinafter the term “zone” in relation to “zone associated with specific vehicle axle load policies relevant for the operation of the vehicle” refers to a geographical zone and/or a time zone. The term “geographical zone” may refer to any geographical area in connection to which a vehicle may operate, which zone is associated with specific vehicle axle load policies relevant for the operation of the vehicle. The term “geographical zone” may refer to a road or road segment along which the vehicle is travelling during vehicle operation. The term “geographical zone” may refer to a bridge. The term “time zone” may refer to the time during which specific vehicle axle load policies are required. A geographical zone and a time zone may be combined, e.g. a geographical zone is associated with specific vehicle axle load policies relevant for the operation of the vehicle during a certain time zone, e.g. during a certain time of the day.
Hereinafter the term “specific vehicle axle load policies relevant for the operation of the vehicle” in relation to “at least one zone associated with specific vehicle axle load policies relevant for the operation of the vehicle” may be any policies that may affect the vehicle operation regarding vehicle axle load. A vehicle axle load policy may be defined by one or more attributes describing a wanted behaviour in relation to vehicle operation in connection to a geographical zone and/or time zone. A vehicle axle load policy may be affected by e.g. road conditions, weather situation or the like. A vehicle axle load policy may be static, e.g. a manually drawn geographic zone, i.e. geographic area, where e.g. the axle load during vehicle operation shall not exceed a certain maximum vehicle axle load, e.g. a regulation by law. A vehicle axle load policy may be dynamic, e.g. the policy is automatically created based on rules, e.g. if the road temperature for a certain type of road is x degrees Celsius and the amount of rain is y mm/hour, the policy is to adapt the axle load for that zone, e.g. a road segment. A vehicle axle load policy may be informative or enforcing. An informative policy means that the operator of the vehicle is informed to adapt to a certain vehicle axle load during vehicle operation. An enforcing policy means that adaption of the vehicle axle load during vehicle operation to a vehicle axle load policy is automatic. A vehicle axle load policy may be a rule/regulation set by e.g. authorities, i.e. legal regulation for a certain geographical zone and/or time zone. A vehicle axle load policy may be a regulation set by e.g. a vehicle owner for a certain geographical zone and/or time zone. A vehicle axle load policy may be created in the vehicle. A vehicle axle load policy may be created in an off-board Zone Management system, which may be an external server unit, the so called cloud, an external data centre or any other means suitable for being operably connected to a vehicle, i.e. a control arrangement of a vehicle. A vehicle axle load policy may be created by an external data provider such as a Road Authority, City, Commercial Data provider, Open Data provider, Transport Buyer etc.
Hereinafter the term “vehicle operation” refers to any operation of the vehicle which may be relevant for any zone associated with specific vehicle axle load policies relevant for the operation of the vehicle. For example driving on a forest road the vehicle axle load that such a road may handle may differ if the road is wet or dry.
Hereinafter the term “allowable total amount of specific vehicle axle loads” comprised in a zone may refer to the total load allowable in that zone. The zone may e.g. be a road portion, a bridge or the like.

To the data communications port 599 e.g. the links connected to the control unit 100 may be connected.
When data is received on data port 599 it is temporarily stored in second memory portion 540. When the received input data has been temporarily stored, data processing device 510 is set up to perform execution of code in a manner described above. The signals received on data port 599 may be used by apparatus 500 for determining at least one zone associated with specific vehicle axle load policies relevant for the operation of the vehicle. The signals received on data port 599 may be used by apparatus 500 for determining a specific vehicle axle load of the at least one vehicle. The signals received on data port 599 may be used by apparatus 500 for adapting the vehicle operation of the at least one vehicle based on the determined specific vehicle axle load as well as the specific vehicle axle load policies associated with the at least one zone so as to fulfil those policies. The signals used by apparatus 500 for adapting the vehicle operation of the at least one vehicle may comprise signals used for distributing the vehicle weight onto a relevant number of vehicle axles. The at least one zone associated with specific vehicle axle load policies comprises an allowable total amount of specific vehicle axle loads. The signals received on data port 599 may be used by apparatus 500 for determining an allowable number of the vehicles for which the specific vehicle axle load has been determined. The signals used by apparatus 500 for adapting the vehicle operation of the at least one vehicle comprises signals used for adapting the number of vehicles in the at least one zone.
