System and method for estimating a weight of a load in a bucket of a work vehicle

A processor-based system, comprising:

• a non-transitory memory configured to store executable routines;
• and
• a processor configured to execute the routines stored in the non-transitory memory, wherein the routines, when executed, cause acts to be performed, comprising:
• obtaining a speed of an actuator of a lift coupled to a bucket;
• comparing the speed to an instantaneous command provided to a hydraulic valve coupled to the actuator;
• estimating a hydraulic pressure drop across the hydraulic valve based on the comparison of the speed to the instantaneous command to estimate pressures in the actuator;
• determining a hydraulic force of the actuator;
• and
• estimating a weight of a load in the bucket of the work vehicle based on the estimated pressures in the cylinder and the hydraulic force.

One or more non-transitory computer-readable media encoding one or more processor-executable routines, wherein the one or more routines, when executed by a processor, cause acts to be performed comprising:

• obtaining a speed of an actuator of a lift coupled to a bucket of a work vehicle;
• comparing the speed to an instantaneous command provided to a hydraulic valve coupled to the actuator;
• estimating a hydraulic pressure drop across the hydraulic valve based on the comparison of the speed to the instantaneous command to estimate pressures in the actuator;
• determining a hydraulic force of the actuator;
• and
• estimating a weight of a load in the bucket of the work vehicle based on the estimated pressures in the actuator and the hydraulic force.
