<p><P>PROBLEM TO BE SOLVED: To prevent over-rotation of an input rotating speed due to erroneous learning of a shift point when learning and correcting the shift point during up-shift so that the input rotating speed reaches a target maximum rotating speed. <P>SOLUTION: When making shift determination of up-shift, this shift control device determines whether a high acceleration request up-shift means 120 performs the up-shift in accordance with a shift point nomchg where a learning value gno is reflected, and uses a learning value reflection checking means 126 for setting a learning value reflecting flag A=ON when the high acceleration request up-shift means 120 performs the up-shift. Only in the case of the learning value reflecting flag A=ON, it permits a shift point learning and correcting means 124 to learn and correct the shift point nomchg, therefore preventing the erroneous learning resulting from mismatch between the reflection of the learning value gno to shift control and the learning and correction of the shift point nomchg and preventing over-rotation of a turbine rotating speed NT due to the erroneous learning. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
