A method and system for controlling unloading of a vehicle transporting a load of unprocessed material from a first location to a second location are described, wherein the second location includes a material processing device and a storage for unprocessed material. The method includes receiving a signal indicative of a level of unprocessed material contained in the material processing device; determining, based on the signal, whether an estimated level of unprocessed material contained in the material processing device is below or above a threshold at an estimated time of arrival of the vehicle at the material processing device; and, directing the vehicle towards the material processing device when the estimated level of unprocessed material contained in the material processing device is below the first threshold; or directing the vehicle towards the storage when the estimated level of unprocessed material contained in the material processing device is above the first threshold.

Method and system for controlling unloading of a load-carrying vehicle

The invention relates to a system and a method for determining a target vehicle speed for a vehicle moving between a starting location and a target location at a worksite. The method comprising: determining a first expected time-of arrival at the target location for a first vehicle; determining a second expected time-of arrival at the target location for a second vehicle, wherein the second expected time-of arrival is later than the first expected time-of arrival; determining a first time difference as the difference between the first expected time-of-arrival and the second expected time-of-arrival; estimating a fuel consumption for the first vehicle for reaching the target location at a current vehicle speed; estimating if the fuel consumption of the first vehicle for reaching the target location can be reduced by reducing the vehicle speed; and if the fuel consumption can be reduced, reducing the speed of the first vehicle to a target vehicle speed, wherein the target vehicle speed is higher than a threshold speed determined based on the first time difference.

Method and system for determining a target vehicle speed of a vehicle operating at a worksite

A method including determining a total amount of unprocessed material that has been dumped into the material processing device during a first time period determining a total amount of unprocessed material that has been processed during the first time period; determining a reference level of unprocessed material at the first point in time; predicting, based on the current level of unprocessed material contained in the material processing device and on an expected future processing rate of the material processing device at least one of an earlier and a later point in time at which the level of unprocessed material is expected to fall below a lower or upper limit; establishing a desired time-of-arrival period extending between a start point and an end point corresponding to the earlier and later points in time respectively; and adapting a speed of the first load-carrying vehicle.
