<p><P>PROBLEM TO BE SOLVED: To provide a transmission controller by which traveling performance or the like is improved. <P>SOLUTION: The transmission controller 60 for performing speed change control as a function of traveling states comprises first judging means S11, S51 for judging whether a difference between a mean value of a revolution speed of a driving wheel and a transmission output speed falls within a given range or not, a second judging means S12 for judging whether a difference in driving wheel speed is beyond a given range or not, and a first speed change control means 13 for making the shift to a first speed change schedule when it has been judged that the difference fell within a given range by the first judging means 11 and besides the difference in driving wheel speed was beyond a given value by the second judging means 12. In this case, there are provided a third judging means S53 for judging whether the revolution speed of the driving wheel is larger than that of a driven wheel or not and a second speed change control means S55 for making the shift to a second speed change schedule when it has been judged that the difference fell within a given range by the first judging means 51 and besides the revolution speed of the driving wheel was larger than that of the driven wheel by the third judging means S53. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
