To accurately determine a congestion state, in a vehicle for transmitting a drive force of an engine to drive wheels via a fluid joint.SOLUTION: A congestion determination device mounted to a vehicle for transmitting a drive force of an engine to drive wheels via a fluid joint has a control part for performing control for making a preceding vehicle traveling in front of the vehicle perform following traveling while maintaining a prescribed inter-vehicle distance by bringing a lockup clutch of the fluid joint into a connection state or a disconnection state, and a traveling state determination part for determining whether or not a congestion state occurs on the basis of an accumulation value of a time at which the lockup clutch is in the disconnection state during the following traveling.SELECTED DRAWING: Figure 1
【課題】エンジンの駆動力を流体継手を介して駆動輪に伝達する車両において、渋滞状態を精度よく判定すること。【解決手段】エンジンの駆動力を流体継手を介して駆動輪に伝達する車両に搭載される渋滞判定装置は、前記車両の前方を走行する先行車に対して、前記流体継手のロックアップクラッチを接続状態又は切断状態としながら、所定の車間距離を維持しつつ追従走行を行うように制御する制御部と、前記追従走行中における前記ロックアップクラッチが前記切断状態である時間の累積値に基づいて、渋滞状態であるか否かを判定する走行状態判定部と、を有する。【選択図】図1
