To provide a driving force control device for an electric vehicle that allows smooth starting after executing single-phase lock avoidance control that suppresses excessive temperature rise in either of driving force sources provided in a pair of left and right drive wheels.SOLUTION: A driving force control device for an electric vehicle includes a first motor for driving a left drive wheel, a second motor for driving a right drive wheel, and a stopping maintenance device for maintaining the state where the electric vehicle is stopped. When the electric vehicle is stopped by outputting driving torque from the first motor and the second motor, the device determines whether one motor has exceeded a predetermined temperature (Step S2). When it is determined that one motor has exceeded a predetermined temperature, the device executes single-phase lock avoidance control that activates the stopping maintenance device and reduces the driving torque of each motor (Steps S3, S4).SELECTED DRAWING: Figure 6

    【課題】左右一対の駆動輪にそれぞれに設けられた駆動力源のいずれか一方の過剰な温度上昇を抑制する単相ロック回避制御を実行した後に、スムーズに発進することができる電動車両の駆動力制御装置を提供する。【解決手段】左側駆動輪を駆動する第1モータと、右側駆動輪を駆動する第2モータと、電動車両を停止した状態を維持する停止維持装置とを備え、第1モータと第2モータとから駆動トルクを出力することによって電動車両を停止させている場合に、一方のモータが所定温度以上に昇温したことを判定し(ステップS2)、一方のモータが所定温度以上に昇温したことが判定された場合に、停止維持装置を作動させ、各モータの駆動トルクを低減する単相ロック回避制御を実行する(ステップS3,S4)。【選択図】図6
