Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a turning behavior controller of a vehicle for minimizing energy consumption during turning. SOLUTION: A unification controller 30 is provided with: a cornering drag estimation part 30c for estimating cornering drag during turning based on vehicle motion state quantity; and a minimization controlled variable setting part 30d for setting the combination of target turning quantity δ_tar and target yaw moment generation quantity Mmot_tar from which the target vehicle motion state quantity is acquired as target controlled variables so that the sum of a loss power estimate Pdrag as a value acquired by converting vehicle drive power loss due to cornering drag into the output power of motors 3RR and 3RL and motor power quantity Pmot_loss of the motors 3RR and 3RL can be minimized.
