PROBLEM TO BE SOLVED: To provide a method for attenuating judder of a power transmission device in a vehicle comprising an electric motor as a drive motor.SOLUTION: An electric motor set value torque (MEm_new) which actuates an electric motor for driving a vehicle is calculated from an electric motor request torque (MEm_setp) corresponding to a torque concerning a current request, and a correction torque (s). The correction torque (s) is calculated as a function of the electric motor request torque (MEm_setp) and a correction factor (y), the correction factor (y) is decided based on a rotational speed (n) of the electric motor. Oscillation of a power electric device is diagnosed based on the rotational speed of the electric motor, and judder of a power transmission device is attenuated by a closed-loop control system having the power transmission device and the electric motor.SELECTED DRAWING: Figure 2

    【課題】駆動モータとして電気モータを備えた車両の、動力伝達装置のジャダーを減衰させる方法を提供する。【解決手段】車両を駆動する電気モータを作動させるための電気モータ設定値トルク(MEm_new)を、現在のリクエストに係るトルクに対応する電気モータリクエストトルク(MEm_setp)、及び補正トルク(s)から計算する。補正トルク(s)は、電気モータリクエストトルク(MEm_setp)と補正率(y)の関数として計算し、補正率(y)は、電気モータの回転速度(n)に基づいて決定する。動力電動装置の振動は、電気モータの回転速度に基づいて診断され、動力伝達装置と電気モータを有する閉ループ制御システムにより、動力伝達装置のジャダーを減衰させる。【選択図】図2
