Abstract
Official abstract text for this publication.
To provide a vehicle drive device capable of efficiently driving a vehicle by using in-wheel motors without falling into the vicious cycle between enhancement of driving via the motors and an increase in vehicle weight. The present invention is a vehicle drive device that uses in-wheel motors to drive a vehicle and includes in-wheel motors (20) that are provided in wheels (2b) of a vehicle (1) and drive wheels, in which the in-wheel motors generate the maximum output power in a high revolutions range equal to or more than a predetermined number of revolutions that is more than zero.
First claim
Opening claim text (preview).
1 . A vehicle drive device that uses an in-wheel motor to drive a vehicle, the vehicle drive device comprising: an in-wheel motor that is provided in a wheel of the vehicle and drives the wheel, wherein the in-wheel motor generates maximum output power in a high revolutions range equal to or more than a predetermined number of revolutions that is more than zero. 2 . The vehicle drive device according to claim 1 , wherein the in-wheel motor is an induction motor. 3 . The vehicle drive device according to claim 1 , wherein the in-wheel motor directly drives the wheel in which the in-wheel motor is provided, without intervention of a deceleration mechanism. 4 . The vehicle drive device according to claim 1 , further comprising: a body side motor that is provided in a body of the vehicle and drives the wheel of the vehicle, wherein the body side motor generates maximum output power in a low revolutions range less than the predetermined number of revolutions. 5 . The vehicle drive device according to claim 4 , wherein the body side motor is a permanent magnet motor. 6 . The vehicle drive device according to claim 1 , further comprising: a body side motor that is provided in a body of the vehicle and drives the wheel of the vehicle; and a battery and a capacitor that supply electric power for driving the body side motor and/or the in-wheel motor, wherein a voltage of the battery is applied to the body side motor and a voltage of the battery and the capacitor that are connected in series is applied to the in-wheel motor. 7 . A vehicle drive device that uses an in-wheel motor to drive a vehicle, the vehicle drive device comprising: an in-wheel motor that is provided in a wheel of the vehicle and drives the wheel, wherein the in-wheel motor generates maximum output power in a high vehicle speed range equal to or more than a predetermined vehicle speed that is more than zero.
