    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: An apparatus includes a stop/start module in operative communication with an engine. The stop/start module structured to determine whether a stopping event has occurred, determine whether an inhibiting condition is activated, turn off the engine for at least a portion of time in response to determining that a stopping event has occurred, and determine an actual stop ratio for the engine based on a number of times the engine is turned off in response to determining the occurrences of stopping events. Turning off the engine is inhibited in response to determining that an inhibiting condition is activated. The inhibiting condition is activated based on the actual stop ratio for the engine being greater than a target stop ratio at a beginning of a driving event. The target stop ratio is based on an operating parameter.

    Abstract: A device includes at least one of a brake position sensor operationally coupled to a brake and providing a brake position signal, or a clutch position sensor operationally coupled to a clutch and providing a clutch position signal. The device further includes a controller having a communication module structured to interpret the at least one of the brake position signal or the clutch position signal, and a collection module structured to collect vehicle dynamics information. The controller further includes a vehicle dynamics module structured to interpret the vehicle dynamics information, and a sensor diagnostics module structured to determine a failure of at least one of the clutch position sensor or the brake position sensor in response to the vehicle dynamics information and at least one of the clutch signal or the brake signal.

    Abstract: A system and method are disclosed for controlling a power split in a hybrid powertrain having an engine and a motor. According to at least one aspect of the present disclosure, the method includes selecting a displaced fuel consumption value for the engine based on a quantity of available reclaimed energy in a battery, where the displaced fuel consumption value favors using the quantity of available reclaimed energy at relatively high load conditions, operating the engine at a condition based on the displaced fuel consumption value to generate engine power to meet at least a portion of a power demand, and operating the motor to generate motor power sufficient to supply a remaining power demand not met by the engine power. The system includes a controller configured to perform the operations of the method.
