1. A control system for assisting an operator of a working machine, the working machine comprising a bucket arranged to receive a load to be unloaded to a load receiving vessel, the control system comprising processing circuitry arranged in communication with an operator interface, wherein the processing circuitry is adapted to:
estimate a difference between a desired payload for the load receiving vessel and an accumulated weight of buckets of loads already unloaded to the load receiving vessel using the bucket,
determine if the difference corresponds to an estimated weight for a fully loaded bucket or to an estimated weight for a half-loaded bucket, and
instruct, using the operator interface and based on the determination, an operator of the working machine to unload a fully loaded bucket or a half-loaded bucket to the load receiving vessel, wherein
the estimated weight for a fully loaded bucket corresponds to the heaviest bucket load of a plurality of consecutive bucket loads, or
the estimated weight for a fully loaded bucket corresponds to an average of a plurality of consecutive bucket loads.
