Abstract: Systems and apparatuses include one or more processing circuits comprising one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to: determine at least one reason for a deserter to exit a first platoon; determine a deserter position within the first platoon; communicate the deserter exit to the first platoon after determination of the at least one reason for the deserter to exit the first platoon based at least in part on the deserter position; adapt a behavior of the first platoon to allow the deserter to exit the first platoon; and reconfigure the remaining vehicles from the first platoon into a second platoon.

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: 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: 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.

Abstract: A system includes a hybrid power train comprising an internal combustion engine and electrical system, which includes a first and second electrical torque provider, and an electrical energy storage device electrically coupled to first and second electrical torque provider. The system further includes a controller structured to perform operations including determining a power surplus value of the electrical system; determining a machine power demand change value; in response to the power surplus value of the electrical system being greater than or equal to the machine power demand change value, operating an optimum cost controller to determine a power division for the engine, first electrical torque provider, and second electrical torque provider; and in response to the power surplus value of the electrical system being less than the machine power demand change value, operating a rule-based controller to determine the power division for the engine, first, and second electrical torque provider.
