摘要	PURPOSE:To carry out speed change control coping with a decrease in the density of intake-air during running on a high land, in a high temperature area or the like, by controlling the speed change in such a speed change pattern that is compensated so as to cope with an actual engine output power in accordance with a detected density of an intake-air. CONSTITUTION:An air density detecting means detects an intake-air flow rate for engine output control values such as a throttle valve opening degree and the like, an engine torque detected by a torque sensor or the like, and an actual engine output condition obtained by a basic fuel injection volume or the like. Accordingly, when the engine output power is insufficient, an intake-air density condition such as a decrease in the intake-air density or the like, is detected. Further, a speed change control means carries out, in accordance with the detected intake-air density, a speed change pattern which is compensated so that shift-up is made by an engine output power control which is larger than that in a usual speed change pattern if it is determined that the intake-air density is for example, lower than a reference value. Thereby it is possible to carry out the speed change control coping with a true engine output, irrespective of variations in the intake-air density.
