To provide a vehicle controller capable of preventing start failure of a vehicle on a compacted snow uphill path or the like, improving accelerating performance, and preventing giving deceleration feeling to a driver.SOLUTION: When a traction control is started (TCS interposition) in a step S1, a rear wheel increase rate, namely an increase rate of rotation speed of wheels becomes larger than a threshold A in a step S2, and an opening number (clutch opening number) of a clutch becomes equal to or more than N times in a step S3, and uphill impossible determination is established (ON) in a step S4, a traction control part executes a traction control limit operation (step S5). In the traction control limit operation, the traction control part executes any of temporary inhibition of the traction control, increase of a target slip amount in a step-state, and gradual increase of the target slip amount.SELECTED DRAWING: Figure 2 【課題】車両の圧雪登坂路等での発進不良を防止でき、加速性能を向上でき、ドライバへ減速感を与えることを防止できる車両の制御装置を提供すること。【解決手段】トラクション制御部は、ステップＳ１でトラクション制御が開始（ＴＣＳ介入）され、ステップＳ２で後輪上昇率、すなわち車輪の回転速度の上昇率が閾値Ａより大きくなり、ステップＳ３でクラッチの開放回数（クラッチ開放回数）がＮ回以上になり、ステップＳ４で登坂不可判定が成立（ＯＮ）した場合、トラクション制御制限動作を実行する（ステップＳ５）。このトラクション制御制限動作では、トラクション制御部は、トラクション制御を一時禁止すること、目標スリップ量をステップ状に増加させること、又は目標スリップ量を徐々に増加させること、の何れかを実施する。【選択図】図２
