Vehicle motion control apparatus, and vehicle motion control method

A vehicle motion control apparatus that the travel stability of a vehicle can be maintained by appropriately controlling the regenerative braking force in accordance with the wheel slip state or the road surface friction coefficient, and that the amount of regeneration of regenerative energy by the electric motor 13 can be ensured under various situations which may range from gradual braking to rapid braking is provided. A braking/driving force allocation unit of the vehicle motion control apparatus allocates braking/driving force to a front wheel 7FL, 7FR and a rear wheel 7RL, 7RR on the basis of braking/driving force required for the vehicle 50 and decreases the braking/driving force for one of the front wheel 7FL, 7FR and the rear wheel 7RL, 7RR for which the braking/driving force is generated by the electric motor 13 in response to a decrease in the ratio of braking/driving force to a slip ratio of at least one of the front wheel 7FL, 7FR and the rear wheel 7RL, 7RR.
