Abstract: Methods and systems for a powertrain power management in a vehicle with an electric motor, and an engine are disclosed. The methods and systems involve a powertrain that is operatively coupled to the engine and the electric motor, and an optimizer module operatively coupled to the powertrain. The optimizer module receives an operator information to travel a route from a remote management module, receives current route information for the route from a mapping application in response to the operator information, measures current vehicle status information for the hybrid vehicle, and decides a power management strategy for the vehicle based on the current route information and the current vehicle status information.

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: Systems, methods, and apparatuses for improving predictive cruise control and predictive engine off coasting for a vehicle are provided. An apparatus includes one or more processing circuits having 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: receive look ahead information and store the look ahead information in the one or more memory devices; receive vehicle information regarding operation of a vehicle including an engine; determine a coasting opportunity for the vehicle based on the look ahead information and the vehicle information; modulate a cruise control set speed based on the determined coasting opportunity; and turn the engine off during the determined coasting opportunity for the vehicle based on modulation of the cruise control set speed.

Abstract: An apparatus includes a pump, a delivery mechanism in fluid communication with the pump, and a controller communicatively coupled to the pump and the delivery mechanism. The controller is structured to interpret, via a pump diagnostic circuit, first and second pump parameters indicative of first and second pump rates, interpret, via a dosing diagnostic circuit, first and second dosing parameters indicative of at least one of (i) first and second reductant flows or (ii) first and second injector characteristics, determine, via a delivery diagnostic circuit, a delivery status based, at least in part, on the interpretation of the first and second pump parameters and the first and second dosing parameters, and generate, via the delivery diagnostic circuit, a status command indicative at least one of an under-restricted delivery mechanism or an over-restricted delivery mechanism in response to the determination of the delivery status.

Abstract: The enclosed disclosure relates to hybrid vehicles and systems with an engine, a drivetrain with a clutch and a transmission, an electric machine, and a controller. The controller receives lookahead information within a lookahead window and present state information of the hybrid vehicle. The controller determines a predicted coasting opportunity exceeding a predetermined threshold within the lookahead window and determines a cruise control reference speed, a power split between the engine and the electric machine, and a timing of enabling engine-off coasting during the coasting opportunity. The controller deactivates the engine and disengages the clutch at a start of the coasting opportunity when the engine-off coasting is enabled.

Abstract: Systems and apparatuses include a vehicle locator circuit that is structured to receive GPS signal coordinates and a road parameter associated with the GPS signal coordinates. The vehicle locator circuit is further structured to identify a current road segment associated with the GPS coordinates. A map data circuit is structured to store the road parameter and GPS signal coordinates associated with the current road segment. A route response circuit is structured to determine look-ahead parameters characterizing a future road segment based on input received from the vehicle locator circuit and the map data circuit, and a communication interface is structured to communicate the look-ahead parameters to an engine control module for improving vehicle performance during travel on the future road segment.

Abstract: A system has a pump and an injector coupled to the pump. The system further comprises a controller coupled to the pump and the injector. The controller is structured to: determine a change of reductant flow relative to a change of pump rate of the pump; and generate a status command indicative of at least one of an under-restricted injector or an over-restricted injector in response to the determination of the change of reductant flow relative to the change of pump rate of the pump.
