<p>PURPOSE:To prevent the dispersion in the shock of speed change, in an integrated control device for an engine in which fuel cut is carried out at the time of deceleration and an automatic transmission, by forbidding fuel-cut regardless of the operating conditions of the engine when the automatic transmission is in a speed-change condition at the time of deceleration. CONSTITUTION:In a device comprising an accelerator operation detecting means (a) for detecting the operation of an accelerator, a speed-change detecting means (b) for detecting whether or not an automatic transmission is in a speed-change condition, and also a fuel-cut control means (c) by which fuel-cut timing is regulated by the operating conditions of an engine; an integrated control means (d) is provided, by which fuel-cut is forbidden even if the operating condition of fuel-cut is satisfied, when the automatic transmission is in a speed-change condition without stepping-in on an accelerator pedal. When a vehicle is operated without stepping-in on the accelerator pedal, if it is detected by the speed-change detecting means (b) that the automatic transmission is in a speed-change condition, the integrated control means (d) forbids fuel-cut even if the operating condition of fuel-cut is satisfied. Thus, at the time of operation without stepping-in on the accelerator pedal, the dispersion in the shock of speed change due to the presence of fuel-cut can be prevented.</p> |
