Payload determination for work machine
Determining an estimated payload weight of a work machine and in particular the payload in the bucket of an excavator. The excavator comprises a boom and a boom lift electronic actuator configured to actuate the boom, a stick and a bucket coupler. The method comprises determining a preliminary estimated weight value of the payload using a net force on the boom lift electronic actuator and a position of the boom. The net force on the boom lift actuator is determined from a motor current of the boom lift electronic actuator where the motor current is indicative of an electric motor torque and which in turn is indicative of a net force on the actuator. The method further comprises adjusting the preliminary estimated weight value to provide an estimated payload weight value, wherein the adjustment comprises filtering to reduce noise by using a band or low pass filter or by time averaging. The method further comprises outputting the estimated payload weight value. The position of other element such at the stick or bucket couple may also be measured to make the estimate. The payload total may be recorded over time and/or compared with threshold values.
