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: 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.
