1. A vehicle braking/driving force control apparatus, comprising:

  • an actuator for independently driving a front left wheel, a front right wheel, a rear left wheel, and a rear right wheel, thereby generating a braking/driving force representing both a braking force and a driving force on each of the front left wheel, the front right wheel, the rear left wheel, and the rear right wheel;

    a suspension link mechanism for independently coupling the each of the front left wheel, the front right wheel, the rear left wheel, and the rear right wheel to a vehicle body, and converting the braking/driving force on the each of the front left wheel, the front right wheel, the rear left wheel, and the rear right wheel driven by the actuator into a force in a vertical direction of the vehicle body,the suspension link mechanism being configured so that a conversion rate of converting the braking/driving force into the force in the vertical direction of the vehicle body is different between a front wheel side and a rear wheel side;

    target braking/driving force calculation means for calculating target braking/driving forces for the four wheels, including a driver-requested braking/driving force set based on an operation amount of a driver and a motion control braking/driving force necessary for vehicle motion control;

    actuator control means for controlling operations of the actuators by following the target braking/driving forces; and

    distribution setting means for setting a distribution of the driver-requested braking/driving force to the front wheels and the rear wheels so that the distributed driver-requested braking/driving force is larger for the wheels coupled to the suspension link mechanisms having a larger conversion rate than for the wheels coupled to the suspension link mechanisms having a smaller conversion rate.
