Vehicle driving force control apparatus
First Claim
1. A vehicle driving force control apparatus of a vehicle having an electric motor transmitting a drive torque to a first wheel, and a clutch installed between the electric motor and the first wheel, the vehicle driving force control apparatus comprising:
- a clutch control section configured to control engagement and release of the clutch; and
a motor control section configured to control a motor response characteristic by increasing the motor response characteristic of the motor from a first response characteristic to a second response characteristic when the clutch control section releases the clutch.

Abstract
A vehicle driving force control apparatus is provided for a vehicle having an electric motor transmitting a drive torque to a first wheel, and a clutch installed between the electric motor and the first wheel. The vehicle driving force control apparatus basically comprises a clutch control section and a motor control section. The clutch control section is configured to control engagement and release of the clutch. The motor control section is configured to control a motor response characteristic by increasing the motor response characteristic of the motor from a first response characteristic to a second response characteristic when the clutch control section releases the clutch. Preferably, the vehicle driving force control apparatus is configured to cancel insufficient torque generation due to undershoot armature current when controlling armature current of an electric motor and transmitting torque to subordinate drive wheels.
