A METHOD AND SYSTEM FOR DETERMINING A TARGET VEHICLE SPEED OF A VEHICLE OPERATING AT A WORKSITE

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.
