To achieve both the improvement of the fuel efficiency and the comfortable traveling performance.SOLUTION: A gear shift control device 20 of an automobile 1 including an engine 4, a driving motor 5, an automatic transmission 8, and the like. The gear shift control device includes: a gear shift map 50 that defines, for each of gear shift points, thresholds of the number of revolutions to determine a switching start timing of each of the gear positions; a transmission control unit 22b that performs switching between the gear positions on the basis of the gear shift map 50; and a regeneration control unit 21d that controls regeneration. The gear shift map 50 includes a non-cooperative regeneration map that defines thresholds on a lower revolution side than thresholds in a cooperative request map 51 used in cooperative regeneration, and the non-cooperative regeneration map includes a combustion request map 52 that defines thresholds on the lower revolution side and is used when an accelerator is not used, and a travel request map 53 that defines thresholds on a relatively higher revolution side and is used when the accelerator is used.SELECTED DRAWING: Figure 6 【課題】燃費向上と快適な走行性能を両立させる。【解決手段】エンジン４、駆動モータ５、自動変速機８などを備えた自動車１の変速制御装置２０である。変速段の切替開始タイミングを判定するために、回転数に関する閾値が変速点毎に規定されている変速マップ５０と、その変速マップ５０に基づいて変速段を切り替える変速機制御部２２ｂと、回生を制御する回生制御部２１ｄとを有している。変速マップ５０が、協調回生時に用いられる回生要求マップ５１よりも閾値が低回転側に規定されている非協調回生時マップを含み、非協調回生時マップが、閾値が低回転側に規定されていてアクセルの不使用時に用いられる燃焼要求マップ５２と、閾値が高回転側に規定されていてアクセルの使用時に用いられる走り要求マップ５３と、を含む。【選択図】図６
