To highly accurately perform the drive control of an electric vehicle in a manner corresponding to the deterioration state, cell temperature, and charge state of a battery.SOLUTION: A device (C) for controlling the driving of an electric vehicle (V) is provided with: a map storage unit (1) in which a plurality of battery correlation maps (7) defining the relationship of a charge state and battery temperature with an internal resistance are stored in advance so as to correspond to a plurality of battery deterioration states; a map selection unit (3) for selecting one battery correlation map (7) from among the plurality of battery correlation maps (7) in the map storage unit (1) on the basis of the current deterioration state of a battery (B); and a motor output control unit (5) for controlling the output of a vehicle-driving electric motor (M) driven by the battery (B) on the basis of the battery correlation map (7) selected by the map selection unit (3).SELECTED DRAWING: Figure 3

    【課題】電動車両の駆動制御を、バッテリの劣化状態、電池温度、充電状態に対応させて高精度に行う。【解決手段】電動車両(V)の駆動を制御する装置(C)において、複数のバッテリ劣化状態に対応して、充電状態およびバッテリ温度と、内部抵抗との関係を定めた複数のバッテリ相関マップ(7)が予めそれぞれ格納されたマップ格納部(1)と、前記マップ格納部(1)の複数の前記バッテリ相関マップ(7)から、前記バッテリ(B)の現在の劣化状態に基づいて1つのバッテリ相関マップ(7)を選択するマップ選択部(3)と、前記マップ選択部(3)で選択されたバッテリ相関マップ(7)に基づいて、前記バッテリ(B)によって駆動される車両駆動用の電動モータ(M)の出力を制御するモータ出力制御部(5)とを設ける。【選択図】図3
