PROBLEM TO BE SOLVED: To provide a motor drive device which can further improve energy efficiency of a hybrid vehicle and an electric automobile.SOLUTION: A motor drive device includes a motor 3 connected to a drive wheel 7 of a vehicle A, a motor drive circuit 2 connected to the motor 3, and a control device 10 which controls the motor drive circuit 2. When a non-operation state of acceleration operation is continuously detected during travel of the vehicle, the control device 10 makes the motor 3 perform regenerative braking so that braking force more than first braking force T2 acts on the vehicle A in a period L1 of decelerating from a first traveling speed to a second traveling speed during a time when the non-operation state of the acceleration operation is detected. In a period L2 of decelerating from the second traveling speed to a third traveling speed, the control device makes the motor 3 perform the regenerative braking so that braking force less than the first braking force T2 acts on the vehicle A.SELECTED DRAWING: Figure 3

    【課題】ハイブリッド車輌や電気自動車におけるエネルギー効率をより向上させることを可能とするモータ駆動装置を提供すること。【解決手段】車輌Aの駆動輪7と接続されたモータ3と、前記モータ3と接続されたモータ駆動回路2と、前記モータ駆動回路2を制御する制御装置10と、を備え、前記制御装置10は、前記車輌の走行中にアクセル操作の非操作状態が継続的に検出されている場合、前記アクセル操作の非操作状態が検出されたときの第1の走行速度から第2の走行速度まで減速する期間L1においては、前記車輌Aに第1の制動力T2以上の制動力が作用するように、前記モータ3に回生制動を行わせ、前記第2の走行速度から第3の走行速度まで減速する期間L2においては、前記車輌Aに前記第1の制動力T2未満の制動力が作用するように、前記モータ3に回生制動を行わせる、モータ駆動装置。【選択図】図3
