PROBLEM TO BE SOLVED: To provide a controller of a vehicle with a multistage automatic transmission, capable of ensuring excellent responsibility at the time when re-acceleration is requested, while suppressing complication of a hydraulic circuit or increase of fuel consumption due to the enlargement of the capacity of an electric oil pump.SOLUTION: A multistage automatic transmission 2 includes a third speed that cannot be formed by an electric pump 84, and a fourth speed that can be formed by the electric pump 84 and is on a higher shift stage side than the third speed. When the shift stage of the multistage automatic transmission 2 is the third speed in vehicle deceleration, combustion of an engine 1 is stopped, and in combustion stop or in a state where combustion is stopped, the shift stage is changed to the fourth stage by the electric pump 84.SELECTED DRAWING: Figure 5
【課題】油圧回路の複雑化や電動オイルポンプの大容量化による燃料消費の増大を抑えながら、再加速が要求されたときの良好な応答性を確保することができる多段自動変速機付車両の制御装置を提供する。【解決手段】多段自動変速機(2)は、電動ポンプ(84)により形成不可能な3速と、電動ポンプ(84)により形成可能な3速より高変速段側の4速とを備え、車両減速時において多段自動変速機(2)の変速段が3速にあるときに、エンジン(1)を燃焼停止させると共に、その燃焼停止のときに又は燃焼停止されている状態で、変速段を電動ポンプ(84)によって4速に変速させることを特徴とする。【選択図】図5
