PROBLEM TO BE SOLVED: To perform speed change control suitable for respective combustion modes, between spark ignition and premixing compression ignition.SOLUTION: An engine is configured for switching between a premixing compression ignition in which an air fuel mixture in which air and fuel are mixed is compressed in a cylinder for self ignition and a spark ignition of the air fuel mixture which uses a spark of an ignition device. In the premixing compression ignition region, a speed change control of a transmission is performed using a first speed change map for speed change control of the transmission on a target action line (L), meanwhile, in a spark ignition region, speed change control of the transmission is performed using a second speed change map for speed change control of the transmission on a target action line (L). If a requested engine output is within the premixing compression ignition region, the second speed change map is switched to the first speed change map for speed change control of the transmission.SELECTED DRAWING: Figure 4
【課題】火花点火と予混合圧縮着火との相互間で、それぞれの燃焼形態に適した変速制御を行うこと。【解決手段】エンジンは、空気と燃料を混合した混合気を筒内で圧縮して自己着火させる予混圧縮着火と、点火装置の火花を用いた混合気の火花点火とを切替え可能に構成される。予混合圧縮着火領域では、目標作動線(Lh)上で変速機の変速制御を行うための第1変速マップを用いて変速機の変速制御を行う一方、火花点火領域では、目標作動線(Ls)上で変速機の変速制御を行うための第2変速マップを用いて変速機の変速制御を行う。要求エンジン出力が予混合圧縮着火領域内にある場合に、第2変速マップから第1変速マップに切替えて変速機の変速制御を行う。【選択図】図4
