commanding the electric motor and an engine based on a location of the vehicle with respect to the trip route; and commanding the electric motor and the engine to operate in a limited charge depletion mode to a target state of charge of the battery such that a state of charge of the battery follows the reference profile based on the location of the vehicle being in the another segment. ### Claim 2 (depends on 1) The method of claim 1 further comprising assigning the target state of charge of the battery to an end of the another segment. ### Claim 3 (depends on 1) The method of claim 1 further comprising providing suggested segments to a user through the user interface, wherein the segments are partitioned based on driving patterns. ### Claim 4 (depends on 1) The method of claim 1 further comprising providing an alternate trip route for selection through the user interface to provide an increase in vehicle fuel economy. ### Claim 5 (depends on 1) The method of claim 1 further comprising receiving predefined trip zoning information for use in generating the charge reference profile. ### Claim 6 (depends on 5) The method of claim 5 further comprising overriding the user assigned mode such that the state of charge of the battery remains within operating thresholds. ### Claim 7 (depends on 1) The method of claim 1 further comprising updating the reference profile based on a trip route change en route. ### Claim 8 (depends on 1) The method of claim 1 wherein the user assigned mode is charge sustaining. ### Claim 9 (depends on 8) The method of claim 8 wherein the user assigned mode is for an intermediate trip segment. ### Claim 10 (depends on 1) The method of claim 1 wherein the user selected mode is charge depleting at a maximum allowable discharge rate for the battery. ### Claim 11 A method of controlling a vehicle comprising: partitioning a selected trip route into segments; assigning an operational mode to each segment thereby creating a distance mode-map, wherein one segment is a limited charge depletion (LCD) mode; and commanding first and second propulsion devices to operate in the LCD mode to a target battery state of charge such that a battery state of charge follows a reference profile when the vehicle is in the one segment. ### Claim 12 (depends on 11) The method of claim 11 further comprising: assigning an electric-only mode to another of the segments; calculating an amount of battery power used by the electric mode segment and the LCD mode segment; and allocating a distance weighted portion of a remaining amount of battery power to each of the remaining segments. ### Claim 13 A vehicle comprising: an electric motor; a battery coupled to the electric motor; an engine, wherein the electric motor and the engine are coupled to wheels of the vehicle via a transmission; a user interface configured for a user to select a trip route for the vehicle; and an electronic control unit (ECU) coupled to the user interface, the electric motor, the battery, and the engine, wherein the ECU is configured to (i) in response to receiving a user assigned mode of operation for a segment of the trip route, generate a charge reference profile for another segment of the trip route that incorporates a battery charge usage set by the segment and a target battery state of charge at an end of the trip route, (ii) command the electric motor and the engine to the user assigned mode of operation in the segment, (iii) command the electric motor and the engine to operate in a limited charge depletion mode such that a state of charge (SOC) of the battery tracks the reference profile when the vehicle is located in the another segment. ### Claim 14 (depends on 13) The vehicle of claim 13 further comprising a navigation system in communication with the user interface and the ECU. ### Claim 15 (depends on 13) The vehicle of claim 13 wherein one of the user interface and the ECU is configured to partition the trip route into at least one segment. ### Claim 16 (depends on 13) The vehicle of claim 13 wherein the ECU is configured to update the reference profile based on a trip route change en route. ### Claim 17 (depends on 13) The vehicle of claim 13 wherein the user selected mode of operation is a charge sustaining mode.
