PURPOSE:To attain the compatibility between the power feeling in middle and low speed ranges and the facility of accelerating operation, and as well to aim at facilitating the depression of an accelerator over the entire speed range, by providing such a method that one of two kinds of patterns is selected when either one of a vehicle speed and an accelerator opening degree is less than a set value thereof, but a pattern other than both kinds of patterns is selected when both are exceed the set values thereof. CONSTITUTION:When judgement is made such that a vehicle runs in its low or middle speed range, an accelerator opening degree is calculated, and a governor pattern A or B which is not shown is selected from a map stored beforehands in a ROM58B, in accordance with the speed and the opening degree. If the pattern B is selected, a more fuel is injected in comparison with in the pattern A even at the equal opening degree of the accelerator. Further, if the present governor pattern is A or B when judgement is made such that the vehicle speed exceeds is 80km/hr, judgement is made on whether the accelerator opening degree exceeds 60% or not, and if it exceeds the value, a high speed governor pattern C is selected. With this method, even if the accelerator is depressed rapidly upon low or middle speed range running, sufficient fuel injection is made to obtain a power feeling, and meanwhile insensitive fuel injection is carried out upon traffic snarl or backward movement, which facilitates the control operation of the accelerator. Further, upon high speed operation a high fuel injection range may be obtained with a small opening degree of the accelerator. |
