PROBLEM TO BE SOLVED: To provide a control device of a travel transmission device for reducing an uncomfortable feeling caused when a speed difference between right and lift traveling devices is changed during turning.SOLUTION: A control part brings a clutch into an ON state by gradually increasing a transmission amount of power by the clutch in accordance with an operation amount of switching operation when a steering operation member operated artificially is switched from a first operation position to a second operation position. Furthermore, the control part brings the clutch into an OFF state by gradually decreasing the transmission amount of the power by the clutch with an increase in the operation amount when the steering operation member is operated from the second operation position to a third operation position, and moreover, gradually increases a braking force by a braking tool. However, when an operation speed of the switching operation of the steering operation member is greater than or equal to a prescribed speed, the control part gradually increases the transmission amount of the power until the clutch is brought into a transmission state, and then, gradually decreases the transmission amount of the power and gradually increases the braking force by the braking tool.COPYRIGHT: (C)2011,JPO&INPIT【課題】旋回中に左右の走行装置の速度差を変更した際の違和感を低減するための走行伝動装置の制御装置を提供する。【解決手段】制御部は、人為的に操作される操向操作部材が第1操作位置から第2操作位置に切換操作される際に、切換操作の操作量に応じてクラッチによる動力の伝達量を漸増させてクラッチを入り状態とする。また、制御部は、操向操作部材が第2操作位置から第3操作位置に操作される際には、操作量の増加に伴いクラッチによる動力の伝達量を漸減させクラッチを切り状態とするとともに、制動手段による制動力を漸増させる。ただし、制御部は、操向操作部材の切換操作の操作速度が所定速度以上であった場合には、クラッチが伝動状態となるまで動力の伝達量を漸増させた後、動力の伝達量を漸減させるとともに制動手段による制動力を漸増させる。【選択図】図12
