To improve shift responsiveness without increasing shift shock.SOLUTION: A vehicle shift control device is such that a transmission up-shifted by engagement with a dog clutch is connected to the output side of a power source; an input torque input into the transmission when up-shifted is controlled; and a first dog tooth and a second dog tooth engaged with each other when up-shifted are engaged with each other. A controller includes: a torque reduction instructing part reducing the input torque by a prescribe amount when starting the up-shift; a differential rotation frequency detecting part detecting a differential rotation frequency as a difference between the input rotation frequency of the transmission and a synchronous rotation frequency as an input rotation frequency of the transmission after up-shifted; a differential rotation frequency adjustment instructing part reducing a reduction amount of the input torque by the torque reduction instructing part when the differential rotation frequency detected by the differential rotation frequency detecting part becomes a prescribed value or lower.SELECTED DRAWING: Figure 4

    【課題】変速ショックを悪化させることなく変速応答性を向上させる。【解決手段】ドグクラッチの係合によってアップシフトする変速機が、動力源の出力側に連結され、アップシフトの際に変速機に入力される入力トルクを制御する車両の変速制御装置であって、アップシフトの際に互いに噛み合う第1ドグ歯と第2ドグ歯とが噛み合う。コントローラは、アップシフトの開始時に入力トルクを予め定めた量、低下させるトルク低下指示部と、変速機の入力回転数とアップシフト後の変速機の入力回転数である同期回転数との差である差回転数を検出する差回転数検出部と、アップシフトの開始後に、差回転数検出部で検出された差回転数が予め定めた値以下になった場合に、トルク低下指示部による入力トルクの低下量を減少させる差回転数調整指示部とを備えている。【選択図】図4
