PROBLEM TO BE SOLVED: To provide a conveyance system that can suppress a running conveyance vehicle with an elevating stage descended from interfering with other conveyance vehicle.SOLUTION: A conveyance vehicle system comprises: a first conveyance vehicle 101a that runs along a rail 190; and a second conveyance vehicle 101b that runs, preceding the first conveyance vehicle 101a. The first conveyance vehicle 101a comprises: a first speed acquisition unit 12 that acquires a speed of the first conveyance vehicle 101a; a first descending-amount acquisition unit 13 that acquires an amount of descending of a first elevating stage 112a of the first conveyance vehicle 101a; a calculation unit 17 that calculates an interference preventive distance serving as an inter-vehicle distance for preventing interference of either conveyance vehicle on the basis of the speed thereof and the amount of descending; and a control unit 15 that controls a first running vehicle 110a so that the inter-vehicle distance between the first conveyance vehicle 101a and the second conveyance vehicle 101b is equal to or more than the interference preventive distance.SELECTED DRAWING: Figure 4
【課題】昇降台を下降させた状態で走行する搬送車が他の搬送車と干渉することを抑制できる搬送車システムを提供すること。【解決手段】レール190に沿って走行する第1の搬送車101aと第1の搬送車101aに先行して走行する第2の搬送車101bと、を備える搬送車システムであって、第1の搬送車101aは、第1の搬送車101aの速度を取得する第1の速度取得部12と、第1の搬送車101aの第1の昇降台112aの下降量を取得する第1の下降量取得部13と、両搬送車の干渉を防止するための車間距離である干渉防止距離を、上記速度及び上記下降量に基づいて算出する算出部17と、第1の搬送車101aと第2の搬送車101bとの車間距離が、上記干渉防止距離以上となるように、第1の走行車110aを制御する制御部15とを備える。【選択図】図4
