Technical Field
The present invention relates to a method for controlling vehicle operation including axle load control of at least one vehicle during vehicle operation. The invention also relates to a control device for controlling vehicle operation including axle load control of at least one vehicle during vehicle operation. The invention also relates to a system for controlling vehicle operation including axle load control of at least one vehicle during vehicle operation. The invention also relates to a vehicle. Furthermore, the invention relates to a computer program and a computer readable medium.
Background
On certain roads and road segments there may be maximum allowed axle load regulations. The maximum allowable axle load may vary, for example, by road name. For heavy vehicles, such as trucks, this is a problem that must be considered in order to meet such axle load regulations. Heavy vehicles, such as trucks, may be configured with support shafts that can be raised and lowered to distribute the weight of the vehicle over a related number of axles. The following may occur: the vehicle driver may travel at an axle load exceeding the maximum allowable axle load due to, for example, changing to a lower maximum allowable axle load during travel of the vehicle.
Accordingly, there is a need to facilitate control of vehicle operation, including control of axle loads during vehicle operation.
Object of the Invention
It is an object of the present invention to provide a method for controlling vehicle operation including axle load control of at least one vehicle during vehicle operation, which method facilitates controlling the axle load so as to meet axle load specifications.

Detailed Description
In the following, the term "link" refers to a communication link, which may be a physical connector, such as an optoelectronic communication line, or a non-physical connector, such as a wireless connection, e.g. a radio or microwave link.
Hereinafter, the term "region" in relation to "a region associated with a particular axle load specification related to operation of the vehicle" refers to a geographic region and/or a temporal region. The term "geographic area" may refer to any geographic area with which a vehicle may operate, which area is associated with a particular axle load specification related to operation of the vehicle. The term "geographic area" may refer to a road or segment along which a vehicle travels during operation of the vehicle. The term "geographic area" may refer to a bridge. The term "time zone" may refer to the time specified for a particular axle load to be required. The geographic area and the time zone may be combined, for example, the geographic area being associated with a particular axle load specification related to operation of the vehicle during a certain time zone, such as during a certain time of day.
Hereinafter, the term "the specific axle load specification relating to the operation of the vehicle" relating to the at least one region associated with the specific axle load specification relating to the operation of the vehicle may be any specification that may affect the operation of the vehicle with respect to the axle load. Axle load specification may be defined by one or more attributes describing desired behavior with respect to vehicle operation associated with a geographic area and/or a time area. Axle load regulations may be affected by, for example, road conditions, weather conditions, etc. The axle load specification may be static, e.g. a manually drawn geographical area, i.e. a geographical area, wherein the axle load, e.g. during operation of the vehicle, must not exceed a certain maximum axle load, e.g. a maximum axle load specified by law. Axle load specifications may be dynamic, e.g. the specifications are automatically created according to rules, e.g. if the road temperature of a certain type of road is x degrees celsius and the rainfall is y millimeters/hour, the specifications are to adjust the axle load of the area, e.g. road segments. Axle load regulation may be informed or mandatory. The notification regulation means that an operator of the vehicle is notified during the operation of the vehicle to adjust to a certain axle load. Mandatory regulation means that the adjustment of the axle load to the axle load regulation is automatic during vehicle operation. The axle load specification may be, for example, a rule/regulation set by authorities, i.e., laws and regulations in a certain geographical area and/or time area. The axle load specification may be, for example, a rule set by a vehicle owner of a certain geographic area and/or time zone. Axle load specifications may be created in the vehicle. Axle load regulation may be created in an off-vehicle area management system, which may be an external server unit, a so-called cloud, an external data center or any other component adapted to be operatively connected to the vehicle, i.e. the control equipment of the vehicle. Axle load specifications may be created by external data providers such as road authorities, cities, business data providers, open data providers, shipping buyers, and the like.
Hereinafter, the term "vehicle operation" refers to any operation of the vehicle that involves any area associated with a particular axle load specification related to the operation of the vehicle. For example, while driving on a forest road, the axle load that such a road can handle may vary depending on whether the road is wet or dry.
Hereinafter, the term "allowable total amount of a specific axle load" included in a zone may refer to the allowable total load in the zone. Such as road sections, bridges, etc.

The computer program P may be stored in an executable manner or in a compressed state in a separate memory 560 and/or a read/write memory 550.
When it is stated that the data processing apparatus 510 performs a specific function, it is understood that the data processing apparatus 510 performs some part of a program stored in the separate memory 560 or some part of a program stored in the read/write memory 550.
The data processing device 510 may communicate with a data communication port 599 by means of a data bus 515. The non-volatile memory 520 is adapted to communicate with the data processing device 510 via the data bus 512. The separate memory 560 is adapted to communicate with the data processing device 510 via a data bus 511. The read/write memory 550 is adapted to communicate with the data processing device 510 via the data bus 514. For example, a link connected to the control unit 100 may be connected to the data communication port 599.
When data is received on the data port 599, the data is temporarily stored in the second memory portion 540. When the received input data has been temporarily stored, the data processing means 510 is arranged to perform the execution of the code in the manner described above. The signals received on data port 599 may be used by device 500 to determine at least one region associated with a particular axle load specification related to operation of the vehicle. The signal received on data port 599 may be used by device 500 to determine a particular axle load of the at least one vehicle. The signals received on the data port 599 may be used by the device 500 to adjust the vehicle operation of the at least one vehicle based on the determined particular axle load and the particular axle load specifications associated with the at least one zone to meet those specifications. The signals used by the apparatus 500 to adjust the vehicle operation of the at least one vehicle may include signals for distributing the vehicle weight over a related number of axles. The at least one region associated with the particular axle load specification includes an allowable aggregate amount of the particular axle load. The signal received on data port 599 may be used by device 500 to determine an allowable number of vehicles for which a particular axle load has been determined. The signals used by the device 500 to adjust the vehicle operation of the at least one vehicle include signals for adjusting the number of vehicles in the at least one area.
A part of the method described herein may be performed by the device 500 by means of the data processing means 510 running a program stored in a separate memory 560 or read/write memory 550. When the device 500 runs a program, a portion of the methods described herein are performed.
