1. A method, comprising:
- determining a route grade and a route distance;
determining at least one of a section grade and a section length for a plurality of route sections of a travel route for a vehicle based on at least a portion of each of the route grade and the route distance;
determining a cruise control speed mode for the vehicle for each of the plurality of route sections based on at least one of the section grade and the section length;
determining a speed reference command of the vehicle based on at least one of the cruise control speed mode, the section length, the section grade, and a current speed; and
controlling, with a controller, a speed of the vehicle based on the speed reference command.

Abstract
Controlling a speed of a vehicle based on at least a portion of a route grade and a route distance divided into a plurality of route sections, each including at least one of a section grade and section length. Controlling the speed of the vehicle is further based on determining a cruise control speed mode for the vehicle for each of the plurality of route sections and determining a speed reference command of the vehicle based on at least one of the cruise control speed mode, the section length, the section grade, and a current speed.

19. A method, comprising:
-
determining, with a controller, a plurality of route sections along a travel route for a vehicle in active cruise control mode, the plurality of route sections comprising a first route section and a second route section, each of the first route section and the second route section including at least one of a section grade and a section length; determining a vehicle speed mode identification based on at least one of the first route section and the second route section; determining a vehicle speed reference based on at least one of the vehicle speed mode identification, the section length, the section grade, and a current speed; and providing the vehicle speed reference to an output device from the controller. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)

31. An apparatus, comprising:
an electronic controller in operative communication with a vehicle system in active cruise control mode, wherein the vehicle system includes an engine and a plurality of inputs operable to provide signals indicating conditions of at least one of a route, an environment, and the engine, wherein the electronic controller includes; a section grade and surface classification module structured to divide a route grade into one or more sections based on a section length, wherein the one or more sections comprises a current section and a next section; a speed mode determination module structured to determine a vehicle speed mode for each of the one or more sections based on at least one of the current section and the next section; and a speed reference determination module structured to output to a display an indication of a vehicle speed reference command based on at least one of a current speed, the vehicle speed mode, a first length of the current section, a first grade of the current section, a second length of the next section, and a second grade of the next section. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39)
