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 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: Apparatuses, methods, and systems comprising vehicle fleet management systems are disclosed. One embodiment is a method that provides a plurality of predetermined powertrain trim templates, where each of the plurality of predetermined powertrain trim templates specifies a plurality of powertrain trim parameters implementable by an electronic powertrain control system to control one or more operational response characteristics of the powertrain. The method includes selecting one of the plurality of predetermined powertrain trim templates and one of a plurality of vehicles of a vehicle fleet to receive the selected one of the plurality of predetermined powertrain trim templates. In response to the act of selecting one of the plurality of predetermined powertrain trim templates, the method transmits via a telematics network one or more modified powertrain trim parameters. Further, the method receives the modified powertrain trim parameters with a telematics system of the selected one of the plurality of vehicles of the vehicle fleet. Also, the method applies the modified trim parameters with the electronic powertrain control system to control the one or more operational response characteristics of the powertrain.

Abstract: A method of substantially preventing road speed excursions while traversing a road grade includes: determining, by a controller, a predicted over speed for a vehicle during an upcoming downhill grade based on a difference between a predicted engine braking power of the vehicle and an amount of braking power that substantially prevents a speed of the vehicle from exceeding a speed threshold; and responsive to the determination, controlling, by the controller, one or more components of the vehicle to substantially prevent the vehicle from exceeding the speed threshold.
