  • Patent number: 11891066
    Abstract: The invention provides a method for controlling a vehicle (1) comprising a drivetrain comprising at least one drive device (2) adapted to generate mechanical power, the method comprising—controlling the vehicle to perform a mission comprising a plurality of stages (MS1-MS12), —collecting operational data relevant to the operation of the drivetrain, wherein the operational data indicate a de-rate of a component of the drivetrain, a fault of a component of the drivetrain, and/or an environmental condition which influences the drivetrain operation, —determining an expected mission stage (MS1-MS12), —determining, in dependence on the operational data, the propulsive capacity (CA1-CA3) in at least two different operational areas (A1-A3) of the drive device (2), —mapping the operational area propulsive capacities (CA1-CA3) to the expected mission stage (MS1-MS12), and —controlling the vehicle (1) in dependence on said mapping.

  • Patent number: 11796053
    Abstract: Methods for controlling a transmission of a vehicle are provided. Such methods include establishing a desired speed profile for the vehicle when travelling along a road segment, performing a plurality of simulations, each of a vehicle response, in the road segment, to a respective gear control action, wherein the gear control action differs from one simulation to another, wherein the simulations include an aim to keep the speed on the speed profile, or within one or more established limits of deviations from the speed profile, determining costs for the simulated vehicle responses, selecting, in dependence on the determined costs, one of the gear control actions, controlling the transmission with the selected gear control action.

  • Patent number: 11713040
    Abstract: The invention provides a method for controlling braking of a vehicle (1) driving along a downhill portion of a road, the vehicle comprising a propulsion arrangement (2, 3), for the propulsion of the vehicle, the method comprising dividing the road portion into a plurality of sections (RS0-RS2), the sections comprising a first section (RS1), and a second section (RS2) following, in the direction of travel of the vehicle, immediately upon the first section (RS1), determining, for the road portion, a road portion control strategy, with a condition that braking on the road portion is done at least partly by means of the propulsion arrangement (2, 3), wherein determining the road portion control strategy comprises determining a speed (SD21), on the second section (RS2), with an aim to minimize the time travelled on the second section, and/or, where the propulsion arrangement comprises an internal combustion engine (2), and a gearbox (3), determining a gear selection (GS2) on the second section (RS2), with an aim t

  • Patent number: 11618449
    Abstract: The invention relates to a method for a control unit (10) for stopping a vehicle (1) when stopping at different types of stop positions (2, 3, 4), the method comprising the following steps: —(S1) the control unit receiving input about a specific stop position for the vehicle, associated with when the vehicle is about to stop during a stopping sequence, the input being indicative of whether the specific stop position requires a high-precision stop or if a stop with a lower precision can be used; and —(S2) when the stop position requires a high-precision stop, the control unit controlling the stopping sequence such that the vehicle stops with a first stopping precision level with respect to the specific stop position, and when a lower precision can be used for the stop, the control unit controlling the stopping sequence such that the vehicle stops with a second stopping precision level which is lower than the first precision level.
