Abstract: A method for managing emissions from a vehicle having an aftertreatment system is provided. The method includes: receiving, by a controller, information indicative of a temperature of an aftertreatment system of the vehicle and a power output of an engine of the vehicle; comparing, by the controller, the temperature of the aftertreatment system to a temperature threshold; comparing, by the controller, the power output to a power output threshold; and responsive to the comparisons, commanding, by the controller, an aftertreatment system heater to selectively engage and disengage to warm the aftertreatment system of the vehicle.

Abstract: In some implementations, a method may include obtaining target fault data indicating a preselected fault for a vehicle having a hydrogen source. In addition, the method may include obtaining vehicle fault data indicating a fault of the vehicle. The method may include identifying a match between the fault and the preselected fault. Moreover, the method may include purging, in response to the identifying the match, hydrogen from the hydrogen source so as to reduce consequences of a battery thermal event by reducing the likelihood of a hydrogen-fueled fire.

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: One embodiment is a method of operating an electronic control system (ECS) to control an engine to propel a vehicle. The method comprises receiving a throttle command, determining an operation to increase engine cycle efficiency by reducing engine torque below a magnitude corresponding to the throttle command and below a torque curve limit over a first vehicle operation segment and permitting an increase in engine torque above the torque curve limit over a second vehicle operation segment, controlling the engine to output torque below the magnitude corresponding to the throttle command and below the torque curve limit over the first vehicle operation segment, and controlling the engine to output torque above the torque curve limit over the second vehicle operation segment in response to a second received throttle command and constrained by an extended limit on operation of the engine above the torque curve limit.

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, 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 vehicle comprises an aftertreatment system configured to reduce constituents of an exhaust gas. The vehicle also includes a controller configured to determine a predicted load on the vehicle during a route, and adjust at least one of a temperature of the aftertreatment system or an amount of a reductant inserted into the aftertreatment system based on the predicted load.

Abstract: Systems, apparatuses, and methods disclosed provide for receiving internal information, external static information, and external dynamic information of a hybrid vehicle, and selectively enable or disable a stop/start function for the engine of the hybrid vehicle based on the internal hybrid vehicle information, external static information, and external dynamic information. The stop/start function controls selective activation and deactivation of the engine during operation of the hybrid vehicle.
