  • Patent number: 11892482
    Abstract: A method includes determining, by a controller, a presence of an available electrical energy quantity generated from an energy generation event; comparing, by the controller, the available electrical energy quantity to an available energy capacity of a battery storage system; and responsive to determining the available electrical energy quantity exceeds the available energy capacity of the battery storage system, causing, by the controller, a transmission of at least a portion of the available energy quantity to a heat management system.
    Type: Grant

  • Patent number: 11493541
    Abstract: Various systems, methods, and apparatuses disclosed herein provide for receiving pressure data for an accumulator system, the pressure data providing an indication of a pressure in an accumulator tank of the accumulator system; receiving energy data, the energy data indicating an availability of free energy for use to charge the accumulator tank; and activating a charging source of the accumulator tank to charge the accumulator tank based on at least one of the pressure data and the energy data.

  • Publication number: 20200116100
    Abstract: The present disclosure relates to systems and methods for managing engine output. A method includes receiving at least one of a torque input and an acceleration input; generating a torque request for an engine; receiving the torque request; and determining an amount of the torque request that can be provided by a fast response actuator including a spark timing actuator based on a governed torque fraction value based on existing operating conditions of the spark timing actuator and a torque fraction value indicative of a total torque request value and an anticipated future torque demand value. The method includes managing the spark timing actuator to produce the amount of torque; determining a remaining amount of the torque request that cannot be provided the fast response actuator based on an existing operating condition of the engine; and commanding a slow response actuator to provide the remaining amount of the torque request.

  • Patent number: 10508614
    Abstract: The present disclosure relates to a system for managing engine output that includes a machine manager module and a combustion module. In one embodiment, the combustion module includes a slow response pathway and a fast response pathway. The slow response pathway includes managing air and fuel actuators and the fast response pathway includes managing spark timing. According to one embodiment, managing spark timing comprises bringing a spark actuator to the middle of a spark timing range for bi-directional control and involves sacrificing engine efficiency for engine responsiveness. Further, the fast response pathway may be selectively enabled based upon an optimization index.

  • Patent number: 9109521
    Abstract: According to one embodiment, an apparatus for controlling operation of an internal combustion engine includes a conditions module that is configured to determine an out-of-gear condition of the internal combustion engine. The apparatus also includes a permission module that is configured to allow a speed of the internal combustion engine to exceed a maximum engine speed limit if the determined out-of-gear condition meets a threshold, and prevent the speed of the internal combustion engine from exceeding the maximum engine speed limit if the determined out-of-gear condition does not meet the threshold.
