Abstract: Methods and systems for improving fuel economy and reducing emissions of a vehicle with an electric motor, an engine and an energy storage device are disclosed. The methods and systems involve obtaining lookahead information and current state information, wherein the lookahead information includes a predicted vehicle speed, and the current state information includes a current state of charge (SOC) for the energy storage device coupled to the electric motor; and determining, based on the lookahead information and the current state information, a target power split between the energy storage device and 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: 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.
