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.

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.
