<P>PROBLEM TO BE SOLVED: To provide a transmission device for a vehicle of simple and low-costed structure having excellent responsiveness and capable of accurately performing control in transmission by eliminating unnecessary computing as much as possible. <P>SOLUTION: A force detecting sensor 25 for detecting force to be applied to a support part 24 is embedded in the support part 24 of a second bearing 5. A force detecting sensor 27 for detecting force to be applied to a support part 26 is embedded in the support part 26 for supporting a third bearing 15. A transmission control unit 40 controls shifting from an input shaft 2 to an output shaft 3 with characteristics of the preset shifting hydraulic pressure, and when controlling shifting, the transmission control unit 40 compares a target output torque previously set in response to the real input torque with the real output torque, and on the basis of a result of this comparison, corrects shifting hydraulic pressure to be set, and outputs a signal to a hydraulic driving section 11. The transmission control unit 40 determines unusual conditions of the transmission by comparing a frequency analysis value obtained by analyzing frequency of the real output torque with a preset characteristic. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
