To provide a traveling control method of an electric vehicle which can prevent the generation of noise and an impact caused by backlash when an operation of a traveling motor is switched to a power running operation from a regeneration operation, and can make an occupant hardly feel the poorness of a response, and a traveling control device.SOLUTION: This traveling control method includes: a regeneration process (START) for regeneration-operating a traveling motor when an accelerator is not operated during the traveling of an electronic vehicle; a first power running process (S3, S4a, S4b and S5) for power-running operating the traveling motor so as to generate minute torque unrelated to an operation amount of the accelerator during an accelerator invalid period corresponding to a traveling speed of the electric vehicle when the accelerator is operated during a regeneration operation; and a second power running process (S6) for power-running operating the traveling motor so as to generate torque corresponding to the operation amount of the accelerator when the accelerator invalid period is finished.SELECTED DRAWING: Figure 3
【課題】走行用モータの動作が回生動作から力行動作に切り替わる際にバックラッシュによる異音や衝撃が発生するのを防ぐことができ、しかも搭乗者がレスポンスの悪さを感じにくい電動車の走行制御方法および走行制御装置を提供する。【解決手段】本発明に係る走行制御方法は、電動車の走行中にアクセルが操作されなくなると走行用モータを回生動作させる回生工程(START)と、回生動作中にアクセルが操作されると、電動車の走行速度に応じたアクセル無効期間の間、アクセルの操作量とは無関係な微小トルクを発生するように走行用モータを力行動作させる第1力行工程(S3,S4a,S4b,S5)と、アクセル無効期間が終了すると、アクセルの操作量に応じたトルクを発生するように走行用モータを力行動作させる第2力行工程(S6)とを含む。【選択図】図3
