Respective usage values are ascertained corresponding to a duty cycle of the track unit operating at each of one or more selected track commands over a specified (e.g., rolling) time period, wherein the respective usage values are further scaled according to specified factors associated with the respective track commands. An output signal is generated corresponding to a determined intervention event, for example an alert to the operator based on a detected or predicted exceeding of a specified target, based at least in part on the scaled usage values. The specified target may, e.g., be based on a current estimated life state of the track unit relative to an estimated life cycle, or a specified total number of hours the track unit has been in operation. ## Claims ### Claim 1 A method for usage profile monitoring with respect to a ground-engaging track unit of a work vehicle, wherein the ground-engaging track unit is driven according to selected track commands, the method comprising: ascertaining respective usage values corresponding to a duty cycle of the track unit operating at each of one or more selected track commands over a specified time period, wherein the respective usage values are further scaled according to specified factors associated with the respective track commands; and generating an output signal corresponding to a determined intervention event, based at least in part on the scaled usage values. ### Claim 2 (depends on 1) The method of claim 1, comprising: aggregating the scaled usage values over a specified rolling time period; and determining the intervention event based on a comparison of the aggregated scaled usage values with respect to a target value for the track unit. ### Claim 3 (depends on 2) The method of claim 2, wherein the target value is a progressively defined threshold for a current estimated life state with respect to an estimated life cycle of the track unit. ### Claim 4 (depends on 2) The method of claim 2, wherein the target value is a progressively defined threshold for a calculated amount of operating time for the track unit. ### Claim 5 (depends on 2) The method of claim 2, wherein the target value is determined by reference to modeled characteristics for the track unit. ### Claim 6 (depends on 5) The method of claim 5, wherein the usage value is scaled according to the modeled characteristics for the track unit. ### Claim 7 (depends on 6) The method of claim 6, comprising: receiving inputs over time from a plurality of work vehicles having respective track units, the inputs from each work vehicle comprising current and/or historical track unit usage information; developing one or more models having respective life cycle characteristics, respective models being selectively retrievable to ascertain the modeled characteristics for determining the target value and scaling of the usage value for the track unit with respect to a respectively estimated life state and/or monitored usage profile. ### Claim 8 (depends on 7) The method of claim 7, wherein the respective inputs from each work vehicle further comprise one or more of: track unit drive pressure; vehicle load; substrate conditions; and detected movements of a user interface tool corresponding to track commands. ### Claim 9 (depends on 6) The method of claim 6, wherein the modeled characteristics for the track unit are developed at least in part according to historical inputs over time and comprising one or more of: track unit drive pressure; vehicle load; substrate conditions; and detected movements of a user interface tool corresponding to track commands. ### Claim 10 (depends on 2) The method of claim 2, comprising: generating a profile for an operator of the work vehicle based at least in part on previously determined intervention events and/or detected movements of a user interface tool corresponding to the track commands for the usage values; and determining the intervention event further based at least in part on the profile for the operator. ### Claim 11 (depends on 2) The method of claim 2, comprising resetting an estimated life cycle for a vehicle-track unit combination based on a detected change to one or more components of the track unit. ### Claim 12 (depends on 2) The method of claim 2, comprising estimating a new life cycle for a vehicle-track unit combination based on a detected change to one or more components of the track unit. ### Claim 13 (depends on 1) The method of claim 1, wherein a type of the intervention event is based at least in part on the scaled usage value. ### Claim 14 (depends on 13) The method of claim 13, wherein the output signal is provided to a display unit associated with an operator of the work vehicle, and generates a display message corresponding to the type of intervention event. ### Claim 15 (depends on 13) The method of claim 13, wherein the output signal is provided to one or more actuators associated with the track unit and/or work vehicle, for controllably adjusting one or more operations of the track unit and/or work vehicle corresponding to the type of intervention event. ### Claim 16 A work vehicle comprising: a ground-engaging track unit driven in a forward or backward direction, independently or in conjunction with one or more other ground-engaging track unit of the work vehicle, according to selected track commands provided via a user interface tool; and a controller configured to: ascertain respective usage values corresponding to a duty cycle of the track unit operating at each of one or more selected track commands over a specified time period, wherein the respective usage values are further scaled according to specified factors associated with the respective track commands;
