The present invention relates to a support systems, it is used to determine a track with later followed by an agricultural work vehicle, above system includes: to be configured to received mapping unit when the independent region of weeding weeds within the field in crop: what is i) worked is related to the coordinate on the boundary in a field Ii) it is related to the coordinate on the boundary in the independent region of the weeds in the boundary of the field of crop It is configured to receive the electrical parameter unit for the one or more electrical parameters for being related to the Operation Van It is configured to calculate the track of an optimization by the independent region of weeding weeds later followed by the trajectory calculation unit of the engineering truck Wherein the track of the optimization is being relied upon by the basis of the received coordinate of the mapping unit One or more one or more of electrical parameters are received by the electrical parameter unit.
