1. A motor control apparatus for a vehicle having and engine which is connected to a transmission through a clutch, and which is connected to a motor having both driving and power-generating functions, and controlling both driving and power-generating states of the motor based on a traveling state of the vehicle and a running state of the engine, comprising:

  • a vehicle velocity sensor for detecting a vehicle velocity of the vehicle;

    an engine rotational speed sensor for detecting an engine rotational speed of the engine;

    a first clutch switch which becomes off when the clutch is fully engaged, and successively from the fully engaged state becomes on when the clutch is moved toward a partially engaged state;

    a second clutch switch which becomes off when the clutch is fully released, and successively from the fully released state becomes on when the clutch is moved toward a partially engaged state; and

    a motor control means for controlling so as to generate electricity by the motor, determining as the approval of an idling power-generating control state, when at least one of the following two neutral determining conditions, which are set to determine that the transmission is neutral, is satisfied;

    the condition that a vehicle velocity is zero and an engine rotational speed exceeds zero, and the condition that a vehicle velocity is zero and the second clutch switch is off.
