A method for controlling a multi-axle work vehicle based on axle loading may generally include monitoring a load associated with loads transmitted through a pivot pin of a track assembly of the work vehicle, wherein the track assembly is configured to be rotatably coupled to an engine of the work vehicle via an axle assembly. In addition, the method may include estimating an axle load applied through the axle assembly based on the monitored load and providing a control output for the work vehicle based on the estimated axle load.

1. A system for controlling a multi-axle work vehicle based on axle loading, the work vehicle include a chassis and an engine supported by the chassis, the system comprising: a track assembly including a drive wheel and a undercarriage support beam, the drive wheel configured to be rotatably coupled to the engine via an axle assembly, the track assembly further including a pivot pin configured to pivotally couple the undercarriage support beam to the chassis;a sensor configured to monitor a load associated with loads transmitted through the pivot pin; anda controller communicatively coupled to the sensor, the controller being configured to estimate an axle load applied through the axle assembly based on the monitored load, the controller being further configured to regulate the operation of an engine based on the estimated axle load,wherein the pivot pin corresponds to a load-sensing pin such that the sensor is integrated into the pivot pin. 2. The system of claim 1, wherein the controller is configured to compare the estimated axle load to a predetermined load threshold associated with the axle assembly. 3. The system of claim 2, wherein the controller is further configured to reduce a torque output limit for the engine when the estimated axle load exceeds the predetermined load threshold. 4. The system of claim 3, wherein the controller is configured to reduce the torque output limit to a reduced torque output limit ranging from 50% to less than 100% of a maximum torque output for the engine when the estimated axle load exceeds the predetermined load threshold. 5. The system of claim 1, wherein the pivot pin is located inboard or outboard of the drive wheel of the track assembly. 6. The system of claim 1, wherein the axle assembly corresponds to a first axle assembly, the sensor corresponds to a first sensor and the load corresponds to a first load, further comprising: a second track assembly including a second drive wheel and a second undercarriage support beam, the second drive wheel configured to be rotatably coupled to the engine via a second axle assembly, the second track assembly further including a second pivot pin configured to pivotally couple the second undercarriage support beam to the chassis; anda second sensor configured to monitor a second load associated with loads transmitted through the second pivot pin,wherein the controller is communicatively coupled to the first and second sensors, the controller being configured to estimate an axle load differential between the first and second axle assemblies based on the first and second loads, the controller being further configured to reduce a torque output limit for the engine when the estimated axle load differential increases above a load differential threshold. 7. A method for controlling a multi-axle work vehicle based on axle loading, the method comprising: monitoring a load associated with loads transmitted through a pivot pin of a track assembly of the work vehicle, the track assembly configured to be rotatably coupled to an engine of the work vehicle via an axle assembly;estimating an axle load applied through the axle assembly based on the monitored load;providing a control output for the work vehicle based on the estimated axle load;comparing the estimated axle load to a predetermined load threshold associated with the axle assembly; andreducing a torque output limit for the engine when the estimated axle load exceeds the predetermined load threshold. 8.
