Abstract
Abstract A motor control apparatus for a vehicle, including a vehicle velocity sensor; an engine rotational speed sensor; a first clutch switch which becomes off when a clutch is fully engaged, and successively from the fully engaged state becomes on just before the clutch is placed in a partially engaged state; a second clutch switch which becomes off when a clutch is fully released, and successively from the fully released state becomes on just before the clutch is placed in a partially engaged state; and a motor control device for controlling so as to generate electricity by the motor, determining as the approval of the idling power-generating control state, when at least one of the following two conditions 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. The motor control apparatus can control the motor by determining an approval of the various motor control state using the neutral determination of the transmission, without using a mechanical gear position sensor.

Claim 1
Independent Claim
227 words
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.
