Title:
電動機制御方法及び電動機制御装置
Document Type and Number:
Japanese Patent JP7105608
Kind Code:
B2
Abstract:
To propose a method for adaptively changing a speed of lowering generation torque of a motor in re-adhesion control.SOLUTION: A slip/skid detection unit 620 detects an occurrence of slipping/skidding by using a first acceleration α1. A lowering speed determination unit 640 determines a lowering speed of a torque command value by using a second acceleration α2 as reference acceleration. When an occurrence of slipping/skidding is detected, a re-adhesion control unit 680 performs torque lowering control for lowering the torque command value according to a lowering speed determined by the lowering speed determination unit 640. Between the first acceleration α1 and the second acceleration α2, smoothing time widths Ta1, Ta2 are different even though the accelerations are detected from the same shaft speed V.SELECTED DRAWING: Figure 6
