PROBLEM TO BE SOLVED: To provide a speed change control system including a control function that can make the best use of a driver sense of reserve power of an engine in an energy saving operation.SOLUTION: A speed change control system for a vehicle includes: a speed change device 2 for changing speed of rotational power from an engine 1 and outputting the resultant rotational power; a speed change control unit 6 for setting speed change ratio of the speed change device; and an engine control unit 5 for setting an engine rotational speed of the engine. In this system, a rotational speed reducing instruction for reducing the engine rotational speed set by the engine control unit by a predetermined amount on the basis of an operational instruction by a driver's operation is given to the engine control unit 5, and a speed change ratio change instruction for requesting, to a speed changing control unit 6, change of the speed change ratio for compensating for reduction in the engine rotational speed by the rotational speed reducing instruction to maintain vehicle speed is given to the engine control unit 5.

    【課題】エンジンの余力の運転者感覚を省エネルギー運転に生かせるような制御機能を備えた変速制御システムを提供する。【解決手段】エンジン1からの回転動力を変速して出力する変速装置2と、変速装置の変速比を設定する変速制御ユニット6と、エンジンのエンジン回転数を設定するエンジン制御ユニット5とを備えた車両のための変速制御システムが、運転者の操作による操作指令に基づいてエンジン制御ユニットで設定されているエンジン回転数を所定量だけ低減させる回転数低下指令をエンジン制御ユニット5に与えるとともに、車両速度を維持するために当該回転数低下指令によるエンジン回転数の低下を補償するように変速比の変更を変速制御ユニット6に要求する変速比変更指令を与える。【選択図】図1
