A vehicle driving force control apparatus is provided for a vehicle having an electric motor (4) transmitting a drive torque to a first wheel (3L or 3R), and a clutch (12) installed between the electric motor (4) and the first wheel (3L or 3R). The vehicle driving force control apparatus basically comprises a clutch control section (8H) and a motor control section (8G). The clutch control section (8H) is configured to control engagement and release of the clutch (12). The motor control section (8G) is configured to control a motor response characteristic by increasing the motor response characteristic of the motor (4) from a first response characteristic to a second response characteristic when the clutch control section (8H) releases the clutch (12). Preferably, the vehicle driving force control apparatus is configured to cancel insufficient torque generation due to undershoot armature current when controlling armature current of the electric motor (4) and transmitting torque to subordinate drive wheels (1L and 1R).
