To appropriately change shifts of an automatic transmission, to make a vehicle run stably.SOLUTION: A shift controller 1 comprises: an acceleration acquisition unit 11 that acquires a running resistance acceleration due to a running resistance of a self-driving vehicle V; a vehicle speed estimation unit 12 that estimates a vehicle speed after shift change based on the running resistance acceleration and a shift change time required to shift to a gear stage that is a shift candidate; and a gear stage selection unit 13 that selects a gear stage after the shift change so that the vehicle speed after the shift change is within an appropriate vehicle speed of the gear stage of the shift candidate and the vehicle speed of the self-driving vehicle does not exceed a target vehicle speed, based on the appropriate vehicle speed set for the gear stage of the shift candidate and the vehicle speed after the shift change.SELECTED DRAWING: Figure 1
【課題】自動変速機のシフト変更を適切に行い、車両を安定して走行させる。【解決手段】変速制御装置1は、自動運転車両Vの走行抵抗による走行抵抗加速度を取得する加速度取得部11と、走行抵抗加速度と変速候補となるギヤ段へシフト変更するときに要するシフト変更時間とに基づいて、シフト変更後車速を推定する車速推定部12と、変速候補のギヤ段に設定された適正車速とシフト変更後車速とに基づいて、シフト変更後車速が変速候補のギヤ段の適正車速内であり且つ自動走行車両の車速が目標車速を超えないようにシフト変更後のギヤ段を選択するギヤ段選択部13とを備える。【選択図】図1
