PROBLEM TO BE SOLVED: To provide a working machine spraying a predetermined amount of agricultural materials even when the traveling speed of a vehicle is changed due to idling of driving wheels, and holding a stop state of spraying the agricultural materials when the vehicle in a state of incapable of traveling due to slipping moves forward and moves backward.SOLUTION: A control apparatus for a working machine includes: a traveling direction detection part 1A for performing different operation according to each state of a forward movement, a backward movement, and stopping of a vehicle, and detecting a traveling direction of the vehicle A a traveling speed detection part 1B for detecting a traveling speed of the vehicle A and a forward direction determination part 1E. Each state of the forward movement and backward movement of the vehicle A is detected based on the determination result of the forward movement determination part 1E.COPYRIGHT: (C)2014,JPO&INPIT【課題】駆動輪の空転による車両の走行速度の変化が生じても、設定された量の農業用資材を散布するとともに、スリップによる走行不能状態の車両が前進動作及び後進動作したときにおいて、農業用資材の散布の停止状態を保持する作業機を提供する。【解決手段】車両の前進・後進・停止の各状態によって異なる動作を行い、車両Aの走行方向を検出する走行方向検出部1Aと、車両Aの走行速度を検出する走行速度検出部1Bと、進行方向判定部1Eとを備え、車両Aの前進と後進の各状態を、進行方向判定部1Eの判定結果に基づいて検出する。【選択図】図1
