First Claim
Patent Images
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; and
a 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.

Abstract
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.

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; and reducing a torque output limit for the engine when the estimated axle load exceeds the predetermined load threshold. - View Dependent Claims (8, 9, 10, 11)

12. A method for controlling a multi-axle work vehicle based on axle loading, the method comprising:
-
monitoring a first load associated with loads transmitted through a first pivot pin of a first track assembly of the work vehicle, the first track assembly configured to be rotatably coupled to an engine of the work vehicle via a first axle assembly; monitoring a second load associated with loads transmitted through a second pivot pin of a second track assembly of the work vehicle, the second track assembly configured to be rotatably coupled to the engine via a second axle assembly; estimating an axle load differential between the first and second axle assemblies based on the first and second loads; and reducing a torque output limit for the engine when the estimated axle load differential increases above a load differential threshold. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
