Problem to be solved: to provide a work vehicle coordination system capable of carrying out a child working car according to a parent working car.In cooperation with the unmanned locomotiveA parental work vehicle 1p for carrying out a ground work using a working machineA child running target calculating section for calculating a target driving position of the child work car 1C from the running locus of the parent work wheel 1p andBased on parental working parametersThe work operation is performed in the child work carThe working operation is linked to the target running position corresponding to the position of the parent work wheelIt has a child parameter generation part which generates child work operation parameters corresponding to the parent working parameter.Child working car 1CUnmanned control based on the position of the child working car 1C, the target running position, and the child work operation parametersChild driving target calculation sectionAt the time of the backward running in the rebound runUnder the condition that the tail of the child work car does not enter the work width of the parent work carThe target running position is calculated.Diagram【課題】親作業車に倣って子作業車が行うことができる作業車協調システムの提供。【解決手段】無人操縦式の子作業車１Ｃと協調して、作業機を用いた対地作業を行う親作業車１Ｐであって、親作業車１Ｐの走行軌跡から子作業車１Ｃの目標走行位置を算定する子走行目標算定部と、親作業運転パラメータに基づいて、子作業車１Ｃにおいて作業運転が実行されるように、作業運転が実行された親作業車１Ｐの位置に対応する目標走行位置にリンクさせて、親作業運転パラメータに対応する子作業運転パラメータを生成する子パラメータ生成部とを備え、子作業車１Ｃは、子作業車１Ｃの位置である子位置と目標走行位置と子作業運転パラメータに基づいて無人操縦され、子走行目標算定部は、切り返し走行の際の後進走行の際に、子作業車の轍が親作業車の作業幅に入り込まないという条件で、目標走行位置を算定する。【選択図】図１
