<P>PROBLEM TO BE SOLVED: To provide an output control structure for a continuously variable transmission device having a simple structure, capable of attaining a vehicle speed corresponding to the operation position of a main speed change operation member irrespective of manufacturing error in the continuously variable transmission device. <P>SOLUTION: In an initial adjusting mode of a control device 800, when a working vehicle 1 runs actually, there is stored an operation control amount of a main gear shift actuator 830 at predetermined first and second speeds V1 and V2 as first and second operation controlled variables S1 and S2. By interpolating based on the first and second operation controlled variables S1 and S2, there is calculated and stored a control function with respect to the variation of the rotational speed of a drive wheel 30 for the operation control amount of the main gear shifting actuator 830 by performing linear interpolation based on the first and second operation controlled variables S1 and S2. Further, in a normal control mode, the operation control of the main gear shift actuator 830 is carried out based on the operation controlled variable calculated using the control function calculated in the initial adjusting mode. <P>COPYRIGHT: (C)2009,JPO&INPIT |
