Powertrain optimization
First Claim
1. An apparatus, comprising:
- a vehicle operation module structured to receive operation data regarding operation of a vehicle;
an operating state module structured to determine that the vehicle is operating in a non-nominal state responsive to the operation data, the operation data including at least one of an engine speed and an engine torque, wherein the operating state module is structured to determine that the vehicle is operating in a cylinder cutout mode responsive to the engine speed and the engine torque; and
a transmission module structured to adjust a shift schedule of a transmission of the vehicle responsive to the determined non-nominal operating state for the vehicle, wherein the transmission module is further structured to control the transmission based on the adjusted shift schedule.

Abstract
A system for a vehicle includes a powertrain system including an engine, a transmission, a drive shaft, and a final drive. The system also includes a controller communicably coupled to the powertrain system. The controller is structured to: receive vehicle operation data during operation of a vehicle; receive route data for a route of the vehicle, wherein the route data is received in advance of the vehicle traveling the route; determine a cylinder deactivation event has occurred based on the vehicle operation data; determine an adjustment to a shift schedule for the transmission based on at least one of the cylinder deactivation event and the route data; and provide a command to implement the adjustment with the transmission.

8. A vehicle, comprising:
-
a powertrain system including an engine coupled to a transmission; and a controller communicably coupled to the powertrain system, the controller structured to; receive operation data regarding operation of the powertrain system; determine the engine is operating in a non-nominal state responsive to the operation data; adjust a shift schedule for the transmission based on the determined non-nominal state of operation for the engine; and control the transmission based on the adjusted shift schedule, wherein the operation data includes at least one of an engine speed and an engine torque, wherein the controller is structured to determine that the engine is operating in a cylinder cutout mode responsive to the engine speed and the engine torque. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method, comprising:
-
interpreting, by a controller, at least one of vehicle operation data regarding operation of a vehicle, route data regarding an upcoming terrain condition for a route of the vehicle, and dynamic data from at least one of another vehicle and a communications center regarding an upcoming operating condition for the vehicle; determining, by the controller, that the vehicle is at least one of in a non-nominal operating state and about to be in the non-nominal operating state; determining, by the controller, that the vehicle is operating in a cylinder cutout mode based on the operation data indicating an engine torque and an engine speed corresponding with an operation condition for an engine of the vehicle during the cylinder cutout mode; adjusting, by the controller, a shift schedule for a transmission of the vehicle responsive to the determination that the vehicle is in or about to be in the non-nominal operating state; and controlling, by the controller, the transmission based on the adjusted shift schedule. - View Dependent Claims (16, 17, 18)
