  • Patent number: 10124792
    Abstract: Systems, methods and apparatus for controlling operation a hybrid powertrain are disclosed that use low power storage and motor/generator components in line haul operations. In one embodiment, a line haul drive cycle includes a low power motor/generator executing a power assistance operation of the hybrid powertrain powered by electricity from a low power storage responsive to a monitoring by a line haul controller of ascensions of the hybrid vehicle at or near a constant speed over an uneven terrain. The line haul drive cycle further includes the low power motor/generator executing a regenerative braking operation of the hybrid powertrain supplying captured electric energy to the low power storage responsive to a monitoring by the line haul controller of descensions of the hybrid vehicle at or near the constant speed over the uneven terrain.

  • Patent number: 9726096
    Abstract: A system includes an internal combustion engine producing exhaust gases as a byproduct of operation and an aftertreatment system that treats the exhaust gases. The system further includes a controller that is structured to functionally execute operations to enhance the temperature of the aftertreatment system. The controller includes an operating condition monitoring module that interprets a temperature value at a position upstream of a catalyst positioned in the aftertreatment system. The controller further includes an operating condition management module that interprets a threshold temperature value, and an engine management module that provides an engine operation command to continue engine operation in response to the temperature value being at least equal to the threshold temperature value.

  • Publication number: 20170058755
    Abstract: Some exemplary embodiments include an electrically driven cooling system for cooling non-engine components of a vehicle. The electrically driven cooling system includes a closed loop coolant flowpath including an electrically driven coolant pump and a radiator connected to the closed loop coolant flowpath, and one or more components connected in parallel and/or in series in the closed loop coolant flow path that receives the coolant. An electrically driven radiator fan is also operable to cool the coolant in the radiator. The electrically driven cooling system is flow isolated from any mechanically driven cooling system that provides coolant to the engine for vehicles that include an engine.

  • Patent number: 9550429
    Abstract: Disclosed are methods, systems, and computer-readable mediums for managing batteries of a fleet of vehicles. A computing device includes one or more processors configured to receive first battery data related to a first battery of a first vehicle, where the first vehicle is part of the fleet of vehicles, and compare the first battery data to fleet battery data related to one or more other batteries of vehicles in the fleet of vehicles. Based on the comparison a second vehicle in the fleet is determined in which to switch the first battery to improve battery life of the batteries of the fleet.

  • Publication number: 20170008514
    Abstract: A hybrid controller unit includes a detection module, a gear-hold module, a gear-skip module, and an optimizing module. The detection module is structured to detect a deceleration event. The gear-hold module is structured to determine whether a certain gear of a transmission should be maintained for a certain period of time in order to optimize power regeneration during the deceleration event. The gear-hold module is also structured to generate a gear-hold request. The gear-skip module is structured to determine whether the transmission should skip a gear in order to optimize power regeneration during the deceleration event. The gear-skip module is also structured to generate a gear-skip request. The optimizing module is structured to receive the gear-hold request and the gear-skip request and generate a transmission command to be sent to a transmission control unit for actuation.
