Abstract: Disclosed are various techniques to optimize mining operations efficiency in which the mine utilizes mine trucks over a mine route. One such technique includes optimizing engine speed from a speed and torque management system. Such engine speed changes can be determined using information such as road grade data and mine stop locations, or whether the engine is in a retarder mode. Mine operation efficiency can be improved through use of adjustments made to a load acceptance curve. Changes to the load acceptance curve can be made through use of information such as road grade data and target truck speed. Improvements can be made through dynamically adjusted vehicle speed, such as through average route speed adjustments, or route segment adjustments in light of average route speed. A dynamic torque management system can provide efficiencies as limits are applied to torque using look ahead information.

Abstract: Platooning vehicles can result in operational advantages. The platooning formation of a vehicle platoon system is controlled in response to a proximity and speed of a disruptor relative to the platoon formation. The platoon system executes a maneuver to change a lane on a route on which the platoon system is travelling to accommodate the disruptor in response to the speed and location of the disruptor relative to the platoon system.

Abstract: An apparatus includes a torque circuit and a clutch circuit. The torque circuit is structured to monitor a torque demand level of an engine. The clutch circuit is structured to (i) disengage an engine clutch of a transmission to decouple the engine from the transmission in response to the torque demand level of the engine falling below a threshold torque level and (ii) disengage a motor-generator clutch of the transmission to decouple a motor-generator from the engine in response to the torque demand level of the engine falling below the threshold torque level. The motor-generator is directly coupled to the transmission.

Abstract: An apparatus, system, and method are disclosed for preventing turbocharger overspeed in a combustion engine (102). The method includes determining (602) a turbocharger error term (202) as a difference between a nominal turbocharger maximum speed (206) and a current turbocharger speed. The method further includes determining (604) a turbocharger speed derivative with respect to time (204). The method includes calculating (606) a turbocharger control response based on the turbocharger error term (202) and the turbocharger speed derivative with respect to time (204). The turbocharger control response (210) may be a modified turbocharger maximum speed (210A) calculated by determining a reference speed multiplier based on the turbocharger error term (202) and the turbocharger speed derivative with respect to time (204), and multiplying the reference speed multiplier by the nominal turbocharger maximum speed (206). The method thereby smoothly anticipates turbocharger transient events, and prevents an overspeed condition of the turbocharger.
