To provide an electric-vehicular control method and an electric-vehicular control apparatus, which are capable of reliably suppressing vibration caused by an external disturbance while securing the performance of an electric motor.SOLUTION: A control method for an electric vehicle 100 includes: computing a basic torque target value Tm1* representing torque to be output from an electric motor 14 and compensation torque TC for compensating for vibration caused by an external disturbance exerting to the electric vehicle 100; setting a torque margin Tmargin being a variable margin relative to torque (TmaxP,TmaxR) that can be output from the electric motor 14; limiting the basic torque target value Tm1* on the basis of the torque margin Tmargin, thus computing a post-limiting torque target value Tm1-lim*; then computing an eventual torque target value Tmf* on the basis of the post-limiting torque target value Tm1-lim* and the compensation torque TC; and controlling the electric motor 14 in accordance with the eventual torque target value Tmf*.SELECTED DRAWING: Figure 6

    【課題】電動モータの性能を活かしつつ、外乱によって生じる振動を的確に抑制することができる電動車両の制御方法、及び、電動車両の制御装置を提供する。【解決手段】この電動車両100の制御方法では、電動モータ14が出力すべきトルクを表す基本トルク目標値Tm1*、及び、電動車両100に作用する外乱によって生じる振動を補償する補償トルクTCが演算される。また、電動モータ14が出力し得るトルク(TmaxP,TmaxR)に対する可変のマージンであるトルクマージンTmarginが設定される。そして、トルクマージンTmarginに基づいて、基本トルク目標値Tm1*を制限することにより、制限後トルク目標値Tm1-lim*が演算される。その後、制限後トルク目標値Tm1-lim*と補償トルクTCに基づいて、最終トルク目標値Tmf*が演算され、この最終トルク目標値Tmf*にしたがって電動モータ14が制御される。【選択図】図6
