To provide a travel control device for an electric vehicle, capable of preventing a rapid decrease in vehicle speed not intended by a driver when an accelerator opening decreases, and allowing the driver to drive a vehicle without impairing operability.SOLUTION: When a vehicle speed is higher than a prescribed speed, and a change rate of an accelerator opening is less than a prescribed change rate (YES in Step S5), an ECU causes a driving motor to generate non-one-pedal drive braking torque with which the vehicle speed gradually decreases (Step S9). The ECU includes: a driving region in which one-pedal drive braking torque is generated when the accelerator opening decreases; and a braking region in which the non-one-pedal drive braking torque is generated when the accelerator opening decreases. The ECU causes the driving motor to generate the non-one-pedal drive braking torque when: the accelerator opening decreases within the driving region; the vehicle speed is higher than the prescribed speed; and the change rate of the accelerator opening is less than the prescribed change rate.SELECTED DRAWING: Figure 2
【課題】アクセル開度の減少時のドライバの意図しない車速の急減少を防止でき、操作性を損なうことなくドライバが車両を走行させることができる電動車両の走行制御装置を提供すること。【解決手段】ECUは、車速が規定車速より大きく、かつ、アクセル開度の変化率が規定変化率より小さい場合(ステップS5でYES)は、車速が緩やかに減少する非ワンペダルドライブ制動トルクを駆動モータに発生させる(ステップS9)。ECUは、アクセル開度が減少した場合にワンペダルドライブ制動トルクを発生させる駆動領域と、アクセル開度が減少した場合に非ワンペダルドライブ制動トルクを発生させる制動領域と、を有し、駆動領域内でアクセル開度が減少し、車速が規定車速より大きく、かつ、アクセル開度の変化率が規定変化率より小さい場合、非ワンペダルドライブ制動トルクを駆動モータに発生させる。【選択図】図2
