<p><P>PROBLEM TO BE SOLVED: To make correspondence between a shift gear-in finish position and a sensor detecting value accurate in conformity with an actual state, while eliminating influence by deflection of a shift operation force transmitting part. <P>SOLUTION: Up to time t3 whenΔT1 passes from t1, a shift load command is increased up to a shift gear-in load, and a coupling sleeve is shifted and operated to a first speed shift gear-in finish position. During this time, a shift position sensor detecting value increases as illustrated. On and after shift operation time t2 to the first speed shift gear-in finish position, though shift operation is impossible more than that, the sensor detecting value increases by a deflection quantity even on and after the t2 by the deflection of the shift operation force transmitting part. In the t3, the shift load command is reduced up to a reduced load such as the deflection becomes 0. Thus, the deflection is eliminated, and the sensor detecting value reduces on and after the t3, and becomes a first speed shift gear-in finish position corresponding value in t4. In aΔ4 period from time t5 whenΔT3 passes, the sensor detecting value is read more than once, and an average value thereof is stored as the first speed shift gear-in finish position. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
