PROBLEM TO BE SOLVED: To provide a device and method for controlling the traveling posture of a vehicle for precisely acquiring desired longitudinal force, lateral force, and yaw moment. SOLUTION: This traveling posture control device is provided with: a steering amount detection means (S1) for detecting a steering amount of a steering wheel by a driver; a driving force distribution means (S10) for distributing a driving force to each driving wheel based on the detected steering amount; a feasibility decision means (S12) for deciding whether the distributed driving force is feasible; and driving force steering angle setting means (S9, S10, S13) for redistributing the driving force of each driving wheel within the feasible range when the driving force is not feasible, and for setting the steering angle of the steering wheel. The driving force steering angle setting means calculates and sets, on the basis of tire lateral force sensitivity to the driving force change as an index showing the degree of influence on tire lateral change amount of the driving force of each driving wheel and tire lateral force sensitivity to sideslip angle change as an index showing the degree of influence on the tire lateral force change amount of the sideslip angle of each wheel, the combination of the driving force change amount and the steering angle correction amount.
