To provide a coasting control device for releasing a clutch which is interposed between a continuously variable transmission and drive wheels in coasting, being a coasting control device which can reduce a shock or the like resulting from the refastening of the clutch when a vehicle is restored to a normal traveling from coasting.SOLUTION: When a prescribed coasting control condition is satisfied, a coasting control part 51 of a TCU 50 stops an engine 10, and performs coasting control for releasing a forward clutch 42 of a fore-and-aft traveling switching mechanism 40. Then, when a rotation number of a continuously variable transmission 30 reaches a value smaller than a first prescribed rotation number during the execution of the coasting control, the coasting control part 51 gradually fastens the forward clutch 42, and after that, when the rotation number of the continuously variable transmission 30 reaches a second prescribed rotation number or larger which is larger than the first prescribed rotation number, the coasting control part releases the forward clutch 42.SELECTED DRAWING: Figure 1

    【課題】惰性走行時に、無段変速機と駆動輪との間に介装されたクラッチを解放する惰性走行制御装置であって、惰性走行から通常走行に復帰する際のクラッチの再締結に起因するショック等を低減することが可能な惰性走行制御装置を提供する。【解決手段】TCU50の惰性走行制御部51は、所定の惰性走行制御条件が満足されたときに、エンジン10を停止するとともに、前後進切替機構40の前進クラッチ42を解放する惰性走行制御を実行する。そして、惰性走行制御部51は、惰性走行制御の実行中に、無段変速機30の回転数が第1の所定回転数未満になった場合には、前進クラッチ42を徐々に締結し、その後、無段変速機30の回転数が第1の所定回転数よりも高い第2の所定回転数以上になった場合には、前進クラッチ42を解放する。【選択図】 図1
