PROBLEM TO BE SOLVED: To more appropriately estimate the resource consumption of a work vehicle at a specific work site and appropriately calculate the timing of resource supply. A resource supply system for a work vehicle that runs on a work site. A consumption recording unit 62 that records the actual unit consumption of resources as work history together with the work contents, a work plan management unit 52 that manages work plan information including work contents, and a work vehicle that is implemented based on the work plan information. Estimated unit consumption amount of resources consumed per unit work amount of, the estimated consumption amount calculation unit 101 that refers to the work history, and supply timing for supplying resources to the energy source pack based on the estimated unit consumption amount And a progress degree calculating section 501 for calculating the progress degree of the ground work at the work place. The supply management unit 60 corrects the supply timing based on the progress calculated by the progress calculation unit 501. [Selection diagram] Figure 1【課題】特定作業地における作業車の資源消費がより適切に推定され、適切に資源補給のタイミングが算出されること。【解決手段】作業地で作業走行を行う作業車のための資源補給システム。資源の実単位消費量を作業内容とともに作業履歴として記録する消費量記録部６２と、作業内容を含む作業計画情報を管理する作業計画管理部５２と、作業計画情報に基づいて実施される作業車の単位作業量あたりに消費される資源の推定単位消費量を、作業履歴を参照して算出する推定消費量算出部１０１と、推定単位消費量に基づいてエネルギ源パックに資源を補給する補給タイミングを算出する補給管理部６０と、作業地における対地作業の進捗度を算出する進捗度算出部５０１と、を備える。補給管理部６０は、進捗度算出部５０１によって算出された進捗度に基づいて、補給タイミングを補正する。【選択図】図１
