Abstract: A vehicle system, apparatus, and/or method is provided. The vehicle system includes a powertrain including a prime mover and a transmission, and an electronic control system in operative communication with the powertrain including an adaptive cruise control (ACC) controller. The electronic control system is configured to determine a speed profile for a vehicle-in-front of the vehicle system while operating the vehicle system along a route. In response to the speed profile for the vehicle-in-front, the electronic control system is further configured to modify one or more output parameters of the powertrain to control one or more of a vehicle speed, a vehicle acceleration, and a vehicle deceleration of the vehicle system to inhibit control of the one or more output parameters by the ACC controller.

Abstract: A cooling system for an electrified vehicle includes a first cooling loop for circulating coolant for cooling at least one of power electronics and a motor/generator of the vehicle. The first coolant loop includes a heat exchanger for exchanging heat with the coolant in the first cooling loop. A second cooling loop is provided for circulating coolant for cooling a battery of the vehicle. The second cooling loop includes a coolant chiller connected to a refrigeration system of the vehicle for exchanging heat in the coolant received from the battery with the refrigeration system of the vehicle.

Abstract: A method for delaying cylinder reactivation in a vehicle includes identifying, by a controller, a request to exit a cylinder deactivation state. The controller determines if the request is due to a transient condition. If the request is due to the transient condition, the controller analyzes at least one of the transient condition and a condition of the vehicle. The controller determines a first adjustment to the vehicle based on analyzing at least one of the transient condition and the condition of the vehicle. The first adjustment is configured to mitigate the transient condition. The controller implements the first adjustment.

Abstract: A vehicle system includes an engine, a transmission, a differential, and a waste heat recovery (WHR) drive that converts thermal energy into mechanical and electrical energy. The WHR drive can include a WHR power unit structured to convert thermal energy into rotation of a WHR drive shaft. A motor/generator having a motor/generator shaft can selectively operate as a motor or a generator. A mechanical linkage is structured to selectively link an output shaft to one of the WHR drive shaft and the motor/generator drive shaft independently of the other of the WHR drive shaft and the motor/generator drive shaft. The output shaft is selectively coupled to one of the engine, the transmission, or the differential. The vehicle system may also include a traction motor to provide drive to the vehicle. The output shaft can be selectively coupled to the traction motor or the engine.

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, 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.
