  • Publication number: 20240149862
    Abstract: A computer-implemented method is provided for controlling a vehicle driveline comprising a propulsion unit and a transmission. The method uses topographic data in order to provide predictive control of the vehicle driveline, where the driveline comprises a first driving mode and a second driving mode, where the vehicle is driving to a predetermined destination. The method includes receiving topographic data for the route to the predetermined destination, determining a number of predictive parameters for the route, where, in the first driving mode, the vehicle driveline is controlled in an eco-mode in order to provide the lowest possible energy consumption to the predetermined destination, and where, in the second driving mode, the vehicle driveline is controlled in order for the vehicle to arrive at the predetermined destination at a predetermined time.

  • Patent number: 11975931
    Abstract: The present invention relates to a method for moving a heavy object into a confined space. The method comprises providing the heavy object in an initial position, the heavy object having an underside resting on a ground surface and comprising an inducible gas-cushion arrangement which in its inactive state causes the underside of the heavy object to maintain contact with the ground surface; activating the inducible gas-cushion arrangement by forming a gas cushion between the underside of the heavy object and the ground surface, the gas cushion generating a lifting force causing the underside of the heavy object to lose contact with the ground surface; moving the heavy object relative to the confined space until the underside of the heavy object at least levels with the supporting surface of the confined space; and moving the heavy object into its final position utilizing the lifting force of the gas-cushion.

  • Patent number: 11976603
    Abstract: A method performed by a control unit in connection with a pre-heating process of an aftertreatment system for a combustion engine is provided. The control unit obtains a scheduled start time of the combustion engine. The control unit schedules a pre-heating of the aftertreatment system to be completed before the scheduled start time. The control unit detects a start of the combustion engine at an actual start time. In response to the detected start of the combustion engine, and using the actual and scheduled start times, the control unit determines whether the scheduled pre-heating of the aftertreatment system fulfils one or more success criteria. When the one or more success criteria are fulfilled, the control unit triggers a performance increase of the combustion engine.
