PROBLEM TO BE SOLVED: To further improve the convenience of a user even when the power level of an electric power source lowers.SOLUTION: A shift control device 12 can be operated with electric power from an electric power source 35 and controls at least either of a front gear shift device 22 having plural first shift positions and a rear gear shift device 23 having plural second shift positions. The shift control device 12 comprises a voltage sensor 35 detecting a power level of the electric power source 34, and a signal control part 20 capable of controlling the front gear shift device 22 and the rear gear shift device 23 in a coordinated manner. The signal control part 20 individually controls the front gear shift device 22 and the rear gear shift device 23 when the voltage VD detected by the voltage sensor 35 is lower than a first power level VF1.

    【課題】電源のパワーレベルが低下しても使用者の利便性をさらに向上させる。【解決手段】変速制御装置12は、電源35からの電力によって動作可能であり、複数の第1変速位置を有するフロント変速装置22および複数の第2変速位置を有するリア変速装置23の少なくともいずれかを制御する。変速制御装置12は、電源34のパワーレベルを検出する電圧センサ35と、フロント変速装置22およびリア変速装置23を協調して制御可能な信号制御部20と、を備える。信号制御部20は、電圧センサ35によって検出された電圧VDが第1パワーレベルVF1よりも低いとき、フロント変速装置22およびリア変速装置23を個別に制御する。【選択図】図3
