To provide a small electric vehicle capable of performing travel control suitable for a flat road surface or an inclined road surface like an upward slope and delivering turning performance according to a travel state, through intuitive operation of a joystick type operator.SOLUTION: A small electric vehicle comprises: right and left motors connected to right and left drive wheels respectively so as to enable power thereof to be transmitted to the right and left drive wheels; right and left rotation speed sensors; an inclination sensor; a joystick type operator; and a control section. A target vehicle angular speed ω is reduced when a pitch angle P becomes less than a predetermined threshold while turning on an inclined road surface with an inclination degree λ, taking into consideration the pitch angle P and a roll angle R detected through the inclination sensor, equal to or larger than the predetermined threshold, and is returned to a normal angular speed or increased when the pitch angle P becomes equal to or larger than the predetermined threshold.SELECTED DRAWING: Figure 3

    【課題】ジョイスティック型操作子の直感的な操作により平坦路や登坂路などの路面傾斜に適した走行制御と走行状態に応じた旋回特性が得られる小型電動車両を提供する。【解決手段】小型電動車両は、左右駆動輪に個別に動力伝達可能に接続された左右モータ、左右回転速度センサ、傾斜センサ、ジョイスティック型の操作子、および、制御部を備え、傾斜センサに検出されるピッチ角Pとロール角Rを考慮した傾斜度λが所定閾値以上の傾斜面で旋回中に、ピッチ角Pが所定閾値未満になった場合は、前記目標車両角速度ωを低減し、ピッチ角Pが所定閾値以上になった場合は、前記目標車両角速度ωを通常に戻すかまたは増加させる。【選択図】図3
