Claim Text:
1. A vehicle braking/driving force control apparatus, comprising: a motor provided on each of a front left wheel, a front right wheel, a rear left wheel, and a rear right wheel, which is capable of transmitting a torque via gears to each of the wheels, thereby generating a braking/driving force on the each of the wheels; a suspension for coupling the each of the front left wheel, the front right wheel, the rear left wheel, and the rear right wheel to a body, and converting the braking/driving force on the each of the wheels to a force in a vertical direction of the body; target braking/driving force calculation means for calculating a target braking/driving force for the each of the wheels, the target braking/driving force including: a driver-requested distributed driving force acquired by distributing a driver-requested driving force set based on an operation amount by a driver to the each of wheels; and a control braking/driving force for the each of the wheels required for vehicle motion control; and motor control means for controlling an operation of the motor by following the target braking/driving force, the suspension being configured so that a conversion rate of converting the braking/driving force on the each of the wheels into the force in the vertical direction of the body is different between a front wheel side and a rear wheel side, wherein the motor control means includes the conversion rate pre-stored therein, the target braking/driving force calculation means comprising distribution setting means for setting a distribution of the driver-requested driving force to the front wheels and the rear wheels so that a larger driver-requested driving force is distributed to the wheels coupled to the suspensions on a side smaller in the conversion rate than to the wheels coupled to the suspension on a side larger in the conversion rate.
