PURPOSE:To prevent acceleration from being retarded by executing speed-change to the speed-change stage corresponding to the step-in amount and the car-speed in the state where the step-in amount is stabilized, without carrying-out speed-change operation, when the variation amount of stepping-in accelerator pedal is large in the captioned control system. CONSTITUTION:An electronic control type transmission automatically switches speed- change stage on the basis of each signal supplied from a car-speed sensor and an accelerator sensor. That is, the voltage value detected by an accelerator sensor 02 is differentiated in a differentiation circuit 8, and the value thus obtained is compared in a comparator 91 or 92, and only the values within a prescribed range are taken-out as the output of the accelerator sensor 02. When the stepping-in amount of an accelerator pedal varies over three speed-change regions in acceleration, and in other words, when variation arises from P point or P1 point to Q point, the differential value as the variation amount per time in the variation from the third speed to the first speed which is detected by the accelerator sensor 02 is obtained by an electronic controller, and if said value is larger than a prescribed value, speed-change operation is not carried-out on the way even if a speed change signal is transmitted. |
