  • Publication number: 20250187580
    Abstract: A computer system comprising processing circuitry to receive data indicative of a temperature parameter of an engine aftertreatment system positioned in downstream fluid communication with an internal combustion engine of a vehicle, and in response to the temperature parameter of the engine aftertreatment system falling outside a predetermined range control a kinetic energy recovery system connected to a propeller shaft connected to the internal combustion engine to generate power from kinetic energy of the propeller shaft in response to the temperature parameter falling below the predetermined range; or control the kinetic energy recovery system to apply a propulsion torque to the propeller shaft in response to the temperature parameter exceeding the predetermined range.

  • Publication number: 20240343128
    Abstract: A vehicle includes a prime mover, such as an internal combustion engine, driving a transmission shaft, a kinetic energy recuperation system, including an electric machine fitted on the transmission shaft and a supercapacitor for recovering the braking energy delivered by the electric machine, at least one solar panel, that is connected to the electric machine and to the supercapacitor, and a controller that is configured to direct the energy captured by the solar panel(s) either to the electric machine or to the supercapacitor as a function of the torque demand on transmission shaft.

  • Publication number: 20240326574
    Abstract: An energy recovery system for a vehicle is presented. The energy recovery system comprises a Kinetic Energy Recovery System, KERS, for connecting to a propulsion shaft of the vehicle, an internal energy storage device configured to receive and store energy from the KERS, and a processing circuitry configured to cause distribution of energy from the internal energy storage device to the propulsion shaft of the vehicle and/or at least one non-propulsion battery for the vehicle based on an energy level of the non-propulsion battery.

  • Publication number: 20240286481
    Abstract: A vehicle comprises an internal combustion engine, a wheel propulsion shaft, wheels and a kinetic energy recovery system configured to recover and store kinetic energy of the vehicle, and restore the stored energy by propelling the wheel propulsion shaft and/or by cranking the internal combustion engine. To reduce the emissions of the vehicle, a method for operating the vehicle comprises, when the vehicle operates: when the vehicle is not stationary, recovering and storing kinetic energy of the vehicle in the KERS, when the vehicle is stationary, measuring an energy level stored in the KERS and comparing the measured energy level to a predetermined high threshold value, so that the method comprises, if the energy level stored in the KERS is above the predetermined high threshold value: stopping the internal combustion engine, then when the vehicle start is required, propelling the wheel propulsion shaft exclusively by the KERS.

  • Publication number: 20240278784
    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: 20240166129
    Abstract: A computer-implemented method may include operating, by a processor device of a computer system, a vehicle at a predetermined speed. The method may further include receiving, from a sensor device, a sensor signal indicating an abnormal condition. The method may further include receiving, from a sensor device, a sensor signal indicating an abnormal condition. The method may further include, based on the sensor signal, determining, by the processor device, an operation risk. The method may further include, in response to determining the operation risk, activating, by the processor device, an alarm. The method may further include, in response to determining the operation risk, maintaining, by the processor device, operation of the vehicle at the predetermined speed.
