  • Patent number: 12240437
    Abstract: A method for operating a main vehicle along a trajectory, the vehicle belonging to a fleet of vehicles, the main vehicle including a powertrain controlled by a control unit. To diminish the consumption of the vehicle, the method includes analyzing, by an external server, consumption data of each vehicles of the fleet of vehicles having previously travelled on said trajectory; based on the analyzed consumption data, identifying, by the external server, an improvable-consumption section of the trajectory; and providing to the control unit from the external server with instructions to restrict consumption of the powertrain on the improvable-consumption section.

    Abstract: A computer system comprising processing circuitry configured to handle wheel slip a vehicle is provided. The vehicle comprises a first axle. The first axle comprises at least two wheels. Each of the at least two wheels of the first axle is drivable by at least two hydraulic motors. The processing circuitry is configured to obtain a slip condition of the vehicle. The processing circuitry is configured to, based on the obtained slip condition, trigger an adjustment of pressure and/or flow to be supplied to at least one of the at least two hydraulic motors in the vehicle. Triggering the adjustment comprises triggering an adjustment of pressure and/or flow between at least two hydraulic motors, and/or triggering adjustment of pressure and/or flow supplied by a source.

  • Publication number: 20240227567
    Abstract: A security system circuit for a vehicle includes an electronic main control unit, at least one electronically operated switch, which is arranged on an input line of an electric load of the vehicle. Each electronically operated switch is controlled by the main control unit and is configured to switch between a connected configuration. The electronically operated switch allows electricity to flow through the input line between a main electric power source of the vehicle and the electric load, and a cutoff configuration, where said electronically operated switch prevents electricity from circulating through the input line between the main power source and said electric load, a safety switch, configured to be activated by a user of the vehicle. The safety switch is configured to control the main control unit, so that each electronically operated switch switches to its cutoff configuration when the safety switch is activated.

  • Publication number: 20230347890
    Abstract: A method of activating cruise control for a vehicle in motion is described. The vehicle speed is continuously acquired. A maximum allowable speed on the path currently travelled by the vehicle is determined. A value V1 for a limit speed is selected based on and below the determined maximum allowable speed. A time range of T units of time is selected based on the maximum allowable speed. The average speed is continuously calculated based on the continuously acquired speed measurements for the most recent T units of time. Upon determination that the speed of the vehicle exceeds the value V1 and that during the most recent T units of time the speed has deviated less than or equal to a predefined allowable deviation from the last calculated average speed, the cruise control is automatically activated to operate the vehicle at said last calculated average speed.
