  "textContent": "An arithmetic device that obtains a minimizing solution, which minimizes a predetermined evaluation function while satisfying a predetermined constraint, includes a first arithmetic operator that sets at least one point on a boundary of the evaluation function obtained from the constraint as at least one of solution candidates and determines a solution that minimizes the evaluation function from among the solution candidates as a provisional solution, and a second arithmetic operator that calculates a solution that gives an extreme value of the evaluation function from a predetermined expression and specifies the minimizing solution based on the solution that gives the extreme value and the provisional solution. The arithmetic device obtains the minimizing solution without performing iterative calculation. A control device () including an arithmetic device operator () serving as the arithmetic device, calculates braking and driving forces of respective wheels () using a minimizing solution obtained on the basis of a total braking and driving force of a vehicle (), a total difference between left and right braking and driving forces, and lateral forces and vertical loads of the respective wheels (). The constraint includes, for each of front and rear actuators (-), not exceeding a maximum difference between left and right torques and a maximum torque.",
