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.

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.

System and method for improving a battery management and accumulator system

A powertrain including a prime mover and an electronically controllable clutch. The powertrain structured selectably engages the clutch to provide power from the prime mover to drive one or more ground contacting wheels and to selectably disengage the clutch to decouple with one or more ground contacting wheels. The electronic control system operatively communicates with the prime mover and the electronically controllable clutch, and uses a predictive cruise control (PCC) controller and an idle coast management (ICM) controller, to control vehicle speed during concurrent operation of the PCC controller and the ICM controller.

Optimization of concurrent operation of predictive cruise control and idle coast management control

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.

Arbitration strategy for slow response and fast response torque requests

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.
