    • PROBLEM TO BE SOLVED: To achieve the comfortable adjusting characteristics of a transmission for a driver, by arranging means which determines a speed adjusted depending on each operating parameter detected. SOLUTION: The position α of an accelerator pedal 107 is supplied to a block 102. Further, a transmission output engine speed and the actual value Nsi of a vehicle straight advancing speed are inputted in the block 102 so as to calculate a transmission input target engine speed Nps . At this time, the transmission gear ratio Isoll of the transmission is obtained as quotients (Nps /Nsi ) of the transmission target input engine speed and the transmission output engine speed. The transmission output rotational speed Nsi , the accelerator pedal position α and an accelerator pedal position changing rate α' differentiated in block 106 are supplied to the block 105 so as to calculated a driver type characteristic value FT. The transmission input target engine speed Nps formed in the block 102 is filtered in a block 103, and supplied as a target rate Npsf to a transmission gear ration adjusting device 104.
