To make it possible to drive a vehicle having a drive motor configured as a winding field type synchronous motor in a situation where no field current can be supplied.SOLUTION: A vehicle drive control method is provided such that when a field current can be supplied to a field winding, a basic drive mode is executed for adjusting a drive point of a drive motor so as to be included in a basic drive range. When no field current can be supplied to the field winding, an abnormal drive mode is executed for stopping the field current and adjusting the drive point so as to be included in an abnormal drive range. In particular, the basic drive range is defined as a range of drive points that produce drive force by basic output torque that is a sum of field torque and reluctance torque of the drive motor. Further, the abnormal drive range is defined as a range of the drive points for generating drive force by the reluctance torque of the drive motor.SELECTED DRAWING: Figure 1
【課題】巻線界磁型同期電動機として構成される駆動モータを備えた車両において、界磁電流の供給ができない状況であっても走行を可能とする。【解決手段】界磁巻線に界磁電流が供給できる場合には駆動モータの駆動点を基本駆動領域に含まれるように調節する基本駆動モードを実行し、界磁巻線に界磁電流が供給できない場合には界磁電流を停止するとともに駆動点を異常時駆動領域に含まれるように調節する異常時駆動モードを実行する車両駆動制御方法を提供する。特に、基本駆動領域は、駆動モータの界磁トルク及びリラクタンストルクの和である基本出力トルクによって駆動力を生成する駆動点の範囲として定められる。また、異常時駆動領域は、駆動モータのリラクタンストルクによって駆動力を生成する駆動点の範囲として定められる。【選択図】図1
