Abstract: A system, method, and apparatus includes management of coasting during operation of a vehicle. Speed of a vehicle is monitored during a coasting event and is compared against a threshold to determine whether to remain coasting or re-engage an engine to a driveline. If instantaneous speed exceeds the threshold, predicted speed can be used to determine whether to permit short duration excursions, or to re-engage the engine to the driveline. These techniques can be used whether the vehicle is slowing down below a threshold or speeding up above a threshold.

Abstract: A system, method, and apparatus include a controller structured to predict a change in speed of a vehicle in advance of upcoming terrain and inhibit a coasting event if the speed exceeds a limit. In one form a velocity of the vehicle is predicted using a physics based model of the vehicle within a look ahead window in front of a vehicle. Such a look ahead window can be distance or time based. In another, speed of a vehicle is monitored during a coasting event and is compared against a threshold to determine whether to remain coasting or re-engage an engine to a driveline. The threshold is a function of road grade, and permits a larger deviation from set speed at low grade than at high grade. The function can be based on road grade and vehicle weight.

Abstract: 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.

Abstract: A method for optimizing operation of a fleet of vehicles includes providing an optimization network including a plurality of nodes and a plurality of connections therebetween. The nodes define all potential destinations in the network for freight delivery or pickup. The connections define all potential sequences of nodes traversable over the network. The method determines a pre-optimization simulation matrix including a plurality of sets of energy expenditures for traversing respective ones of each of the connections. Each of the plurality of sets of energy expenditures accounts for permutations of a plurality of different vehicle powertrains present in a fleet of vehicles. The method performs an optimization using the pre-optimization simulation matrix, fleet information indicating locations and energy states of a plurality of vehicles in the vehicle fleet, mission information indicating a pickup or delivery destination for a plurality of items of freight, and a fleet optimization objective.

Abstract: Disclosed are various techniques to optimize load delivery management of multiple vehicles along route. The optimization can involve evaluating vehicle-in-front information along with look ahead data to determine a recommended speed target and/or idle stop times and durations. The optimization can also involve determining bottleneck conditions from one or more vehicles and/or one or more infrastructure conditions and providing one or more recommended actions in response thereto.
