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.

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: Controls for improved performance of a vehicle equipped with start-stop control logic are disclosed. Deviation from nominal engine start-stop control logic for the internal combustion engine occurs when a predetermined mission related type of stop event will occur or is occurring that is different from other stop event types that are controlled by the nominal engine start-stop control logic. At least one of a location and a payload associated with the mission related stop event type is provided as an input to the controller before the vehicle arrives at the stop event so that operating parameters of the vehicle are controlled accordingly.

Abstract: Diagnosis system, method, and apparatus for a starting system are discloses herein. The method comprises receiving a run condition parameter for a vehicle, receiving a fueling system engagement parameter and an associated time threshold for the fueling system engagement parameter, and receiving an ignition command for turning an engine of the vehicle from an off state to an on state. If the run condition parameter is met, the method receives time data indicative of a time duration from reception of the ignition command to reach or substantially reach the fueling system engagement parameter, compare the time duration to the associated time threshold, and diagnose a starting system of the vehicle based on the comparison.

Abstract: Apparatuses, methods and systems for hybrid powertrain control are disclosed. Certain example embodiments control an internal combustion engine and a motor/generator of a hybrid electric powertrain. Example controls may determine a total output demanded of a powertrain based at least in part upon an operator input, a battery output target based upon a battery state of charge and independent of the operator input, and an engine output target based upon the total output demanded and the battery output target. Such example controls may further determine a constrained engine output target, a modified battery output target based upon the total output demanded and the constrained engine output target, and a constrained battery output target based upon the modified battery output target and a battery constraint. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and figures.
