  • 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: 20230158978
    Abstract: A truck adapted to transport Dangerous Goods. The truck includes a chassis on which is arranged a battery; a cab mounted on the chassis, a solar panel for charging the battery, said solar panel being arranged on cab roof. A first relay is configured to disconnect the battery and a second relay, distinctive from the first relay, configured to disconnect the solar panel. At least one manual control element is located in the cab configured to simultaneously open the first and second relays. A crash sensor detects a crash situation and an electronic control unit is configured to disconnect the second relay, the electronic control unit being connected to the crash sensor so that the crash sensor sends a signal to the electronic control unit when a crash situation is detected.

  • Publication number: 20220203932
    Abstract: The invention relates to a functionality limiting system (110) for a motorized vehicle (100) provided with a motion system, comprising: first sensor means (101) adapted to sense if the power is on and providing a first sensing signal; second sensor means (102a-102d) adapted to sense one or several operational parameters relative to at least one part of the vehicle (100) and providing a second sensing signal; deactivation means (103) adapted to verify if a deactivation condition is met and providing a deactivation signal; a control unit (104) in communication with the first and second sensor means (101; 102a-102d) and the deactivation means (103), the control unit (104) receiving said first and second sensing signals and said deactivation signal, the control unit (104) being adapted to control the speed and/or the power supplied by the motion system in response to said first and second sensing signals and said deactivation signal, in such a manner that said speed and/or said power is limited in an activated mo
