Provided is a brake/drive force control device capable of performing appropriate brake/drive force control in which the state of a tire is reflected. The device is provided with: a front wheel front-rear force generation unit (10); a rear wheel front-rear force generation unit (20); a tire slip angle output unit that outputs tire slip angles of front and rear wheels; a tire lateral force output unit that outputs tire lateral forces of the front and rear wheels; a slip rate output unit that outputs the slip rate of the front and rear wheels on the basis of the tire slip angle and the tire lateral force; a tire lateral force change rate output unit that outputs a change rate of the tire lateral force with respect to the slip rate; a target yaw moment setting unit that sets a target value of the additional yaw moment; and a braking/driving force distribution control unit (130) that controls the output sharing ratio of the front-wheel front-rear force generation unit and the rear-wheel front-rear force generation unit on the basis of the target value of the additional yaw moment and the rate of change of the tire lateral force of the front and rear wheels with respect to the slip rate.

    本发明提供能够进行反映了轮胎的状态的适当的制动驱动力控制的制动驱动力控制装置。该装置构成为具备:前轮前后力产生部(10);后轮前后力产生部(20);轮胎滑移角输出部,其输出前后轮的轮胎滑移角;轮胎横向力输出部,其输出前后轮的轮胎横向力;滑移率输出部,其基于轮胎滑移角和轮胎横向力而输出前后轮的滑移率;轮胎横向力变化率输出部,其输出轮胎横向力针对滑移率的变化率;目标横摆力矩设定部,其设定附加横摆力矩的目标值;制动驱动力分配控制部(130),其基于附加横摆力矩的目标值和前后轮的轮胎横向力针对滑移率的变化率来控制前轮前后力产生部和后轮前后力产生部的输出分担比。
