PROBLEM TO BE SOLVED: To provide a control device of a vehicle which suppresses a fastening shock when releasing neutral traveling control.SOLUTION: A control device of a vehicle for controlling the vehicle comprising an automatic transmission 4 having a stepped gear change mechanism 30 having a first fastening element 32 which is fastened when selecting a gear change stage different from a prescribed gear change stage, and a second fastening element 33 which is fastened when selecting a gear change stage different from a prescribed gear change stage, comprises a control unit 12 for performing the rotational synchronization of the stepped gear change mechanism 30 when fastening the first fastening element 32 or the second fastening element 33 during neutral traveling control for making the vehicle travel while bringing the stepped gear change mechanism 30 into a power block state. A fastening time of the first fastening element 32 is longer than a fastening time of the second fastening element 33, and a first threshold for determining the rotational synchronization of the first fastening element 32 is larger than a second threshold for determining the rotational synchronization of the second fastening element 33.SELECTED DRAWING: Figure 5 【課題】ニュートラル走行制御を解除した場合に締結ショックを抑制する車両の制御装置を提供する。【解決手段】所定変速段と異なる変速段を選択するときに締結される第１締結要素３２と所定変速段と異なる変速段を選択するときに締結される第２締結要素３３とを有する有段変速機構３０を有する自動変速機４を備えた車両を制御する車両の制御装置であって、有段変速機構３０を動力遮断状態として車両を走行させるニュートラル走行制御中に、第１締結要素３２、または第２締結要素３３を締結する場合に、有段変速機構３０の回転同期を行う制御部１２を備え、第１締結要素３２の締結時間は、第２締結要素３３の締結時間よりも長く、第１締結要素３２の回転同期を判定する第１閾値は、第２締結要素３３の回転同期を判定する第２閾値よりも大きい。【選択図】図５
