PURPOSE:To smoothly and securely carry out a speed change by selecting correction data consisting of a solenoid output time corresponding to the oil temperature and a duty ratio, and by correcting the full-on time of the solenoid on the basis of the correction data. CONSTITUTION:While receiving the input signals of a vehicle speed sensor 101, a throttle sensor 102, and a shift-lever position switch 103, the duty-data selecting means 106 of an electronic controller 105 sets duty-ratio data by means of the combination between N to D shifts or first to fourth speeds, and the throttle opening. And the duty-ratio data are corrected by a correcting means 108 in response to the time elapsed during the shift between D, 2, L range and P, R, N range being detected by a timer 107, and further the duty-ratio data or the full-on times of solenoids 19 to 21 are corrected by a correcting means 109 through the signal from an oil temperature sensor 23, and the duty- ratio is calculated by a setting means 110 to output speed-change signals to the solenoids 19 to 21. Thus, the quantity of oil can be secured, and the speed change can be smoothly and perfectly carried out. |
