To make it possible to automatically begin regeneration according to appropriate timing.SOLUTION: A motor drive control device of the present invention includes (A) a drive unit that drives a motor, and (B) a control unit that controls the drive unit so that the drive unit performs regeneration when an acceleration of a vehicle in which the motor is mounted is negative and lower than a predetermined value. By taking account of a negative acceleration, automatic regeneration can be begun on an early stage. Noted is that the predetermined value is a value based on an acceleration derived from activation of a mechanical brake. If the control unit controls the drive unit so that the drive unit performs regeneration when the state in which the acceleration of the vehicle is negative and lower than the predetermined value continues over a first predetermined period of time, noise to be generated depending on a road surface state can be readily removed.SELECTED DRAWING: Figure 4

    【課題】適切なタイミングで自動的に回生を開始できるようにする。【解決手段】本発明のモータ駆動制御装置は、(A)モータを駆動する駆動部と、(B)モータが搭載される車両の加速度が負であって且つ所定値以下である場合、回生を行うように駆動部を制御する制御部とを有する。このように負の加速度に着目することで、自動的な回生を早期に開始させることができるようになる。なお、上で述べた所定値は、機械ブレーキの作動によって生ずる加速度に基づく値である。また、制御部が、車両の加速度が負であって且つ所定値以下である状態が第1の所定時間継続する場合に、回生を行うように駆動部を制御すれば、路面状況などによって生ずるノイズを容易に除去できるようになる。【選択図】図4
