To provide a technique enabling preventing erroneous determination of a vehicular slip occurring even when the vehicle is shifting from deceleration to acceleration, in consideration of a backlash.SOLUTION: A control method for an electric vehicle with a motor (4) as a travel drive power source, performs: calculating a motor torque instruction value; detecting a motor angular velocity of the motor connected to a drive wheel; determining whether a drive wheel (9) is slipping on the basis of a transmission characteristic from motor torque to the motor angular velocity including a torsional rigidity of a drive system and a backlash characteristic of gears included in the drive system and on the basis of the detected motor angular velocity; and controlling the motor (4) on the basis of the calculated motor torque instruction value in a case where the drive wheel (9) is determined to be not slipping.SELECTED DRAWING: Figure 2
【課題】バックラッシュの影響を考慮して、車両が減速状態から加速状態に移行する時でも車両のスリップ発生を誤判定することを防止することができる技術を提供する。【解決手段】モータ(4)を走行駆動源とする電動車両の制御方法であって、モータトルク指令値を算出し、駆動輪につながるモータのモータ角速度を検出し、駆動系の捩れ剛性と当該駆動系に含まれるギヤのバックラッシュ特性とを含むモータトルクからモータ角加速度までの伝達特性と、検出したモータ角速度とに基づいて、駆動輪(9)がスリップしているか否かを判定し、駆動輪(9)がスリップしていないと判定された場合は、算出したモータトルク指令値に基づいてモータ(4)を制御する。【選択図】図2
