The invention provides a vehicle body behavior control device which suppresses pitching behavior of a vehicle body through a simple structure. This vehicle body behavior control device is provided in a vehicle (1) provided with: a rear suspension device (210) that supports a wheel (RW) so as to be able to stroke the wheel in a jump direction and a rebound direction with respect to a vehicle body (B), and that has a geometry in which the center (C) of the wheel is moved in a direction in which the wheelbase is expanded and contracted in accordance with the stroke; and a front and rear wheel rotation difference restraining section (40) that restrains a rotation difference between a front wheel driving force transmission mechanism (30) that transmits driving force to the front wheel (FW) and a rear wheel driving force transmission mechanism (50) that transmits driving force to the rear wheel (RW). The vehicle body behavior control device is provided with a front and rear wheel rotation difference restraint control unit (130) that increases the restraint force of the front and rear wheel rotation difference restraint unit when a pitching behavior of the vehicle body occurs.
本发明提供通过简单的结构来抑制车体的俯仰行为的车体行为控制装置。该车体行为控制装置设置于车辆(1),该车辆具备:后悬架装置(210),其以能够使车轮(RW)相对于车体(B)向跳跃方向和回弹方向进行冲程的方式支承所述车轮,并且具有根据冲程而使车轮的中心(C)向使轴距伸缩的方向移动的几何形状;以及前后轮旋转差约束部(40),其对向前轮(FW)传递驱动力的前轮驱动力传递机构(30)与向后轮(RW)传递驱动力的后轮驱动力传递机构(50)之间的旋转差进行约束,并且将该车体行为控制装置设为具备在发生车体的俯仰行为时使前后轮旋转差约束部的约束力增加的前后轮旋转差约束控制部(130)的结构。
