PROBLEM TO BE SOLVED: To provide an electric vehicle driving force control device capable of suppressing a decline in velocity at a sag point with a simple configuration.SOLUTION: An electric vehicle driving force control device comprises: target-driving-force setting means 11 setting a target driving force on the basis of a driver's required driving force; torsional-vibration suppression means 20 that includes disturbance elimination means 19 computing a correction amount for suppressing a torsional vibration generated in a driving system on the basis of a rotation velocity of a motor and eliminating a disturbance torque component contained in the correction amount; command-value computing means 13 computing a motor torque command value by adding the correction amount output from the disturbance elimination means 19 to the target driving force; sag-point determination means 21 determining whether an electric vehicle reaches a sag starting point; and control means 22 controlling the command-value computing means 13 to output the correction amount without via the disturbance elimination means 19 if the sage-point determination means 21 determines the arrival of the electric vehicle at the sag starting point.

    【課題】簡単な構成でサグ地点での速度低下を抑制できる電動車両の駆動力制御装置。【解決手段】運転者の要求駆動力に基づいて目標駆動力を設定する目標駆動力設定手段11と、モータの回転速度に基づいて駆動系に生ずるねじれ振動を抑制するための補正量を演算し且つ補正量に含まれる外乱トルク成分を除去する外乱除去手段19を備えるねじれ振動抑制手段20と、目標駆動力に外乱除去手段から出力される補正量を加算することにより、モータトルク指令値を演算する指令値演算手段13と、電動車両がサグ開始地点に達したかどうかを判断するサグ地点判断手段21と、サグ地点判断手段により電動車両がサグ開始地点に達したと判断されたとき、外乱除去手段を通過させずに補正量を指令値演算手段に出力させる制御手段22とを備える。【選択図】図1
