PROBLEM TO BE SOLVED: To detect an adaptive ratio for the whole acting range of a vehicle by calculating a first adaptive rate from the lapse of time of a vehicle speed. SOLUTION: A vehicle speed is executed by measuring the driving rotational speed of a transmission output shaft by the use of an engine speed sensor 104. The driver of a vehicle sets the output of an engine 101 by the position α of an accelerator pedal 108. The position α of the accelerator pedal 108 is detected by a positioning angle sensor 107, and supplied to a transmission control part 106. A driving engine speed Nab is supplied as a scale against the vehicle speed as well, to the transmission control part 106. Besides, the other parameter can be used in the transmission control part 106. The transmission control part 106 detects a desired transmission gear ratio isoll for an automatic transmission 103 from an input signal. |
