Abstract
(EN)
According to the present invention, a control unit controls torque, in a normal range, in accordance with an ordinary map which indicates the correspondence among the torque, the motor rotational speed, and an accelerator operation amount in the normal range. The control unit controls torque, in a deterioration range, so as to be suppressed more than that in the normal range in accordance with a suppression map which indicates the correspondence among the torque, the motor rotational speed, and an accelerator operation amount in the deterioration range. The control unit switches, when it is determined that the deterioration range has been reached, from the torque control based on the ordinary map to the torque control based on the suppression map through passage of a deterioration-time switching time period required for switching, which is to be performed when deterioration range has been reached, the torque control after a deterioration determination time at which it is determined that the deterioration range has been reached.

Selon la présente invention, une unité de commande commande le couple, dans une plage normale, conformément à une carte ordinaire qui indique la correspondance entre le couple, la vitesse de rotation du moteur et une amplitude d'actionnement de l'accélérateur dans la plage normale. L'unité de commande commande le couple, dans une plage de détérioration, de façon à être supprimé plus que dans la plage normale conformément à une carte de suppression qui indique la correspondance entre le couple, la vitesse de rotation du moteur et une amplitude d'actionnement de l'accélérateur dans la plage de détérioration. Lorsqu'il est déterminé que la plage de détérioration a été atteinte, l'unité de commande commute, de la commande de couple basée sur la carte ordinaire sur la commande de couple basée sur la carte de suppression en passant par une période de commutation de temps de détérioration exigée pour la commutation, laquelle doit être effectuée lorsque la plage de détérioration a été atteinte, de la commande de couple après un moment de détermination de détérioration auquel il est déterminé que la plage de détérioration a été atteinte.

制御部は、正常領域においては、正常領域における、トルク、モータの回転速度、およびアクセル操作量の対応関係を示す通常マップにしたがってトルクを制御し、劣化領域においては、劣化領域における、トルク、回転速度、およびアクセル操作量の対応関係を示す抑制マップにしたがって、正常領域におけるトルクよりも抑制されるようにトルクを制御し、劣化領域になったと判定された場合に、劣化領域になったと判定された劣化判定時から劣化領域になった場合におけるトルクの制御の切り替えに要する時間である劣化時切替時間をかけて、通常マップにしたがったトルクの制御から、抑制マップにしたがったトルクの制御への切り替えを行う。
