PURPOSE:To make automatic correction for turbulence such as noise by re-storing the throttle opening maximum value and minimum value which are changed by a minute amount from their respective present values, and determining the degree of throttle opening subjected to a correction according to a specific formula on the basis of these values obtained. CONSTITUTION:An electronic control device 21 controls shift solenoids 18, 19 and lockup solenoid 20 in a hydraulic circuit 17 of an automatic transmission 11 on the basis of sensing signals given by a shift position sensor 22, car speed sensor 23, and throttle opening sensor 24. Therein the control device 21 stores the voltage data VA for 0% and 100% throttle openings, stores as max. value V0'' the value obtained by adding a minute amount to the max. value V0' of 0% opening, and also stores as min. value V100'' the value aquired by subtracting a minute amount from the min. value V100' of 100% opening. The corrected throttle opening thetaA' is determined from the following formula: thetaA'=(V0''-VA /(V0''-V100''-)X100. |
