In step s 2, in the case of being judged as that the detected value selecting position sensor 20 is not more than setting deviation predetermined value, ECU3 is judged to that speed change gear 2 is the most abnormal, terminates unusual determination action.
On the other hand, in the case of being judged as that the detected value selecting position sensor 20 is more than setting deviation predetermined value, ECU3 drives and selects actuator 17, makes selection piston 16 move the amount (step S3) being equivalent to setting with the difference of the detected value selecting position sensor 20.
Then, ECU3 judges that the detected value selecting position sensor 20 is whether more than setting deviation predetermined value (step S4).Here, in the case of being judged as that the detected value selecting position sensor 20 is not more than setting deviation predetermined value, ECU3 is judged to that speed change gear 2 is the most abnormal, terminates unusual determination action.
On the other hand, in the case of being judged as that the detected value selecting position sensor 20 is more than setting deviation predetermined value, ECU3 make notice device 35 notify there is abnormal message (step S5) in speed change gear 2, terminate unusual determination action.
The effect of the unusual determination action of explanation as implied above is described with reference to Fig. 3 and Fig. 4.Additionally, Fig. 3 and Fig. 4 represents that speed change gear 2 forms the state of the speed change level of 1 gear.
As shown in Figure 3, after making speed change gear 2 form speed change level, in order to maintain the position of choice direction 9 of gearshift tower 12, reduce the oil pressure of the hydraulic oil selecting actuator 17, make directing pin 13 be pressed into the wall of guiding groove 14 of gearshift tower 12 from there through the restoring force of spring 15.
Now, gearshift tower 12 is upspring due to the restoring force of spring 15, selects piston 16 to upspring therewith, as it is shown on figure 3, select piston 16 to leave from relative to the original position of gearshift tower 12, produces gap 45 sometimes.
Therefore, although be provided with spring 26, but in the case of the friction selecting piston 16 is relatively large, piston 16 is selected sometimes cannot to return to original position relative to gearshift tower 12.
Additionally, when selecting actuator 17 not work, when having worked with the not shown oil pump selecting actuator 17 to share oil hydraulic circuit, select the vacuum suction that piston 16 is produced in not shown oil tank, select piston 16 to leave from relative to the original position of gearshift tower 12, produce gap 45 sometimes.
In this state, performing the unusual determination action shown in Fig. 2, thus make selection piston 16 to the direction only mobile space 45 close to gearshift tower 12, the most as shown in Figure 4, select piston 16 to return to the original position relative to gearshift tower 12, gap 45 disappears.
As it appears from the above, in the present embodiment, when being judged to select the testing result of position sensor 20 to exist abnormal, control to select actuator 17 so that selecting piston 16 to move to the direction close to gearshift tower 12.
Thus, in the present embodiment, make selection piston 16 close to gearshift tower 12, make the position being located at the selection position sensor 20 selecting piston 16 return to original position, although therefore, it is possible to preventing the position of gearshift tower 12 from normally judging the malposition being set to gearshift tower 12 by accident.
Additionally, in the present embodiment, it is being judged as that selection piston 16 is from leaving relative to the original position of gearshift tower 12, when being judged to select the testing result of position sensor 20 to exist abnormal, control to select actuator 17, thus do not make notice device 35 notify exception, selection piston 16 is made to move to the direction close to gearshift tower 12, afterwards when being judged to select the testing result of position sensor 20 to exist abnormal, notice device 35 is made to notify exception, therefore, it is possible to prevent from notifying that device 35 notifies exception when not needed.
In addition, in the present embodiment, illustrate the unusual determination action of the speed change gear 2 relative to choice direction 9, but the composition relative to shifting direction 10 of speed change gear 2 is set to identical relative to the composition of choice direction 9, thus, present invention may be equally applicable to the speed change gear 2 unusual determination action relative to shifting direction 10.
Above, although disclose embodiments of the present invention, it is understood that those skilled in the art can apply change without departing from the scope of the invention.It is intended to all of this amendment and equivalent are contained in claim.
