    • In a shift control device operative to determine shift positions based on an absolute positional information related to a mechanical displacement of a shift mechanism, it is intended that the shift positions are accurately determined regardless of disturbance and deterioration with time. It is determined as to whether a varying width of a position voltage PV representing absolute positional information relative to a varying width of a pulse count number CP representing relative positional information is larger than an varying allowable range. When a state, under which difference between the both variations is larger than the varying allowable range, continues beyond a determining time T, a determination is made that persistent disturbance is existed in the position voltage PV, and a correlation between the position voltage PV and the shift positions “P”, “R”, “N” and “D” is learnt and corrected. This allows the correlation to be corrected even if a variation occurs in the position voltage PV due to for instance variations in a disturbance magnetic field or an environmental temperature, a change with time of an output characteristic of a hall element 78, so that the shift position can be determined based on the position voltage PV with increased precision at all times.
    • 在基于与换档机构的机械位移有关的绝对位置信息来确定换档位置的变速控制装置中,意图是随着时间而扰动和劣化而准确地确定换档位置。 确定表示相对于表示相对位置信息的脉冲计数值CP的变化宽度的绝对位置信息的位置电压PV的变化宽度是否大于可变容许范围。 当两个变化之间的差异大于变化容许范围的状态持续超过确定时间T时,确定位置电压PV中存在持续性干扰,并且确定位置电压PV和 学习并校正移位位置“P”,“R”,“N”和“D”。 即使由于例如扰动磁场或环境温度的变化,霍尔元件78的输出特性随时间的变化而导致位置电压PV发生变化,也能够校正相关性,使得偏移 可以随时随地提高精度的位置电压PV来确定位置。
