To provide a behavior control device capable of appropriately distributing driving torque.SOLUTION: A behavior control device 18 for an electric automobile 10 includes a torque arbitration unit 40 which: sets a distribution between a front wheel driving torque and a rear wheel driving torque according to a target yaw rate; when the distribution ratio of the rear wheel driving torque to the front wheel driving torque is less than a limit value, sets the distributed front wheel driving torque to a target front wheel driving torque, and sets the distributed rear wheel driving torque to a target rear wheel driving torque; and when the distribution ratio of the rear wheel driving torque to the front wheel driving torque is equal to or greater than the limit value, sets the target front wheel driving torque and the target rear wheel driving torque such that braking force is generated at least on a rear wheel 12r.SELECTED DRAWING: Figure 2
【課題】適切に駆動トルク配分を行うことができる挙動制御装置を提供する。【解決手段】電気自動車10の挙動制御装置18は、目標ヨーレートに応じて、前輪駆動トルクと後輪駆動トルクとの配分を設定し、前輪駆動トルクに対する後輪駆動トルクの配分比が制限値未満である場合には、配分された前輪駆動トルクを目標前輪駆動トルクに設定し、配分された後輪駆動トルクを目標後輪駆動トルクに設定し、前輪駆動トルクに対する後輪駆動トルクの配分比が制限値以上である場合には、少なくとも後輪12rに制動力を発生させるように目標前輪駆動トルク及び目標後輪駆動トルクを設定するトルク調停部40を有する。【選択図】図2
