To reduce gear shift shock while ensuring sufficient surplus driving force by performing a gear change at more appropriate timing.SOLUTION: A cruise control device 1 controls a gear ratio of a transmission 5 when acceleration and deceleration are automatically performed in a traveling vehicle. The cruise control device 1 includes: an actual accelerator opening acquisition unit 10 that acquires an actual accelerator opening of the vehicle; a final target accelerator opening acquisition unit 11 that acquires a final target accelerator opening, which is the final target accelerator opening when the vehicle is about to accelerate or decelerate; a vehicle speed acquisition unit 12 that acquires a vehicle speed of the vehicle; an accelerator opening comparison unit 13 that acquires larger one of the actual accelerator opening and the final target accelerator opening as a selected accelerator opening; and a gear ratio selection unit 14 that selects a gear ratio of the transmission 5 when the vehicle is about to accelerate or decelerate, on the basis of the selected accelerator opening and the vehicle speed acquired by the vehicle speed acquisition unit 12.SELECTED DRAWING: Figure 1

    【課題】より適切なタイミングで変速を行うことで余裕駆動力を十分に確保しつつ、変速ショックを低減させる。【解決手段】走行制御装置1は、走行する車両において加速及び減速が自動で行われる際に、変速機5の変速比を制御する。走行制御装置1は、車両の実アクセル開度を取得する実アクセル開度取得部10と、車両が加速又は減速を行おうとする場合における最終的な目標アクセル開度である最終目標アクセル開度を取得する最終目標アクセル開度取得部11と、車両の車速を取得する車速取得部12と、実アクセル開度と最終目標アクセル開度とのうち大きい方を選択アクセル開度として取得するアクセル開度比較部13と、選択アクセル開度及び車速取得部12により取得された車速に基づいて、車両が加速又は減速を行おうとする場合における変速機5の変速比を選択する変速比選択部14と、を備えている。【選択図】図1
