A computer-implemented method for managing a mobile hydrogen refuelling system includes obtaining from a hydrogen refuelling vehicle a first set of data relating to the hydrogen refuelling vehicle, obtaining from a hydrogen supply vehicle a second set of data relating to the hydrogen supply vehicle, in the management system, obtaining map data relating to an area of operation of said hydrogen refuelling vehicle and said hydrogen supply vehicle, determining a resupply location based on said first set of data, said second set of data and said map data, and providing the hydrogen refuelling vehicle and/or the hydrogen supply vehicle with navigation instructions to the resupply location for resupplying the hydrogen refuelling vehicle with hydrogen from the hydrogen supply vehicle.

Method, a management system and a mobile hydrogen refuelling system

A material transportation system for a working machine is provided. The material transportation system comprises a load implement body with a plurality of air flow channels. The air flow channels comprise a set of heat insulated air flow channels, and a set of heat transfer channels, wherein each air flow channel of the set of heat insulated air flow channels comprises a heat insulating structure. When the temperature level of the load implement body is below a predetermined threshold limit, pressurized air is directed to the set of heat transfer channels.

Material transportation system

A braking system for a vehicle at least partially propelled by an electric traction motor electrically connected to an electric power system. The braking system comprises an electric machine configured to be electrically connected to the electric power system, the electric machine comprising a first output shaft and a second output shaft, an air blower controllably connected to the first output shaft by a clutch, the clutch being controllable between an open position in which no power is transmitted from the electric machine to the air blower, and a closed position in which power is transmitted from the electric machine to the air blower, and a fluid pump operatively connected to the electric machine via the second output shaft, wherein the fluid pump is arranged in upstream fluid communication with a fluidly operated member and in downstream fluid communication with a fluid tank.

Braking system and method of controlling such a braking system

The disclosure relates to an electrically powered mobile fluid supply system (MFSS) for supplying fluid to a host unit. The MFSS comprises at least one pressurized fluid volume, a fluid dispenser fluidly connectable to the host unit and configured to supply fluid from the at least one pressurized fluid volume to the host unit in a fluid supply operation, and at least one compressor configured to build sufficient pressure for the fluid supply operation in the MFSS. The MFSS is configured to be electrically connected to the host unit and the at least one compressor is configured to be electrically connected to the MFSS and electrically powered by the host unit during the fluid supply operation. The disclosure further relates to a method for supplying fluid to a host unit, to a control unit configured to control the fluid supply operation, and to the MFSS.

Mobile fluid supply system, a method for supplying fluid, a control unit and a vehicle, vessel or craft comprising the mobile fluid supply system

A method of preventing a rollover situation for an articulated vehicle, specifically in relation to the forward vehicle section of the articulated vehicle, is disclosed. A corresponding control unit and a computer program for such an articulated vehicle is also disclosed.

Method and control unit for preventing a rollover situation of an articulated vehicle

A method is provided for controlling the speed of a vehicle that includes a drive train for driving the vehicle and a predetermined preferred speed set. The method includes determining whether or not a substantially constant speed of the vehicle is requested, if it is determined that a substantially constant speed is requested, determining whether the requested speed lies within or outside of the predetermined preferred speed set, and if it is determined that the requested speed lies outside of the predetermined speed set, automatically adjusting the speed of the vehicle to a vehicle speed that is within the predetermined speed set.

Method for controlling the speed of a vehicle

A work machine includes a front section with a front frame, a first set of ground engaging members and a power source for propelling the work machine, a rear section with a rear frame, a second set of ground engaging members and a load-carrying container. The rear section includes an electric drive system adapted for driving at least one ground engaging member of the second set. The rear section is detachably connected to the front section. The power source of the front section is adapted to power the electric drive system in the rear section in an attached state of the front and rear sections. The electric drive system is adapted for driving the at least one ground engaging member of the second set for self-propelling of the rear section in a detached state.

Work machine

A work machine includes a front section with a front frame and a first set of ground engaging members, a rear section with a rear frame and a second set of ground engaging members, and at least one pivot joint between the front section and the rear section allowing the front section to pivot with regard to the rear section. One of the front section and the rear section includes a power source, and the other of the front section and the rear section includes at least one electric motor adapted for driving at least one of the ground engaging members.

Hybrid electrical working machine

A method for controlling a vehicle including a dump body includes automatically monitoring the contents of the dump body during an elevating motion, determining when the dump body has reached a predefined condition during the elevating motion, and controlling the vehicle when it is determined that the dump body has reached the predefined condition.
