PROBLEM TO BE SOLVED: To allow regenerative braking force to work in consideration of an occupant's intention.SOLUTION: A motor drive control device includes: a detection part that detects a regenerative control initiation instruction or cease instruction issued by an occupant; a control coefficient calculation part 1201 that when the detection part detects the regenerative control initiation instruction, identifies first vehicle speed upon detection, and sets a control coefficient for a target regenerative quantity to a predetermined value, that increases a value of the control coefficient if current vehicle speed is higher than the first speed and decreases the value of the control coefficient if the current vehicle speed is lower than the first vehicle speed, until the detection part detects the regenerative control cease instruction; and a control part that controls driving of a motor on the basis of the value of the control coefficient sent from the control coefficient calculation part and the target regenerative quantity.
【課題】搭乗者の意図を加味して回生制動力が働くようにする。【解決手段】モータ駆動制御装置は、搭乗者による回生制御の開始指示又は停止指示を検出する検出部と、検出部により回生制御の開始指示を検出すると、検出時における第1の車速を特定すると共に回生目標量に対する制御係数に所定の値を設定し、検出部により回生制御の停止指示を検出するまで、現在車速が第1の車速より速い場合には制御係数の値を増加させ、現在車速が第1の車速より遅い場合には制御係数の値を減少させる制御係数算出部1201と、制御係数算出部からの制御係数の値と回生目標量とから、モータの駆動を制御する制御部とを有する。【選択図】図6
