Abstract: A method of route planning for an electric vehicle includes obtaining waypoint data that indicates waypoint locations for the electric vehicle. The method also includes generating a map and a plurality of route segments to connect each of the waypoint locations on the map. Further, the method includes calculating an optimal route for the electric vehicle to visit each of the waypoint locations by evaluating the plurality of route segments. In response to detecting changes occurring in conditions associated with each of the plurality of route segments, the method includes recalculating the optimal route for the electric vehicle.

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: A control system, apparatus, and method integrates vehicle speed management and predicted gear shifting of a vehicle by determining current and future engine power requirements from the current and forward-looking route conditions to improve performance, drivability, and/or fuel economy of the vehicle over what is achievable through conventional gear state selection via static calibration tables and conventional shifting strategies. The selection of the vehicle reference speed is responsive to a gear selection to provide increased fuel economy, decreased trip time or combinations thereof.

Abstract: A system for a vehicle includes a powertrain system including an engine, a transmission, a drive shaft, and a final drive; and a controller communicably coupled to the powertrain system. The controller is structured to: receive a shift schedule for the transmission of a vehicle, the shift schedule indicating when shift events occur based on operation of the vehicle; receive vehicle operation data during operation of the vehicle, the vehicle operation data including a current combustion recipe for the engine; determine a predicted impact of a scheduled shift event on a fuel consumption rate of the vehicle based on the current combustion recipe for the engine; determine an adjustment to the scheduled shift event based on the predicted impact; and provide a command to implement the adjustment to the scheduled shift event to the transmission of the vehicle.

Abstract: An apparatus includes an initial planning module, a tandem implementation module, and a scheduler module. The initial planning module is structured to interpret one or more fleet delivery requirements, assets, drivers, and vehicle descriptions. The tandem implementation module is structured to determine a travel schedule with respect to a first vehicle and a second vehicle that enables the first vehicle and the second vehicle to travel in tandem for a least a portion of a route in response to input from the initial planning module. The scheduler module is structured to provide a fleet delivery schedule to the first vehicle and the second vehicle in response to the determination of the tandem implementation module.
