To provide a vehicle body behavior control device which suppresses pitching behavior of a vehicle body in a simple structure.SOLUTION: A vehicle body behavior control device is installed in a vehicle 1 including: a suspension device 210 which supports a wheel RW to be strokable in a bound direction and a rebound direction with respect to a vehicle body B and has a geometry where a center C of the wheel deviates in an extension/contraction direction of a wheel base according to the stroke; and a differential rotation restraining part 40 between a front wheel and a rear wheel which restrains the differential rotation between a front-wheel drive power transmission device 30 transmitting driving power to a front wheel FW and a rear-wheel drive power transmission device 50 transmitting driving power to a rear wheel RW. The vehicle body behavior control device includes a differential rotation restraining control part 130 between a front wheel and a rear wheel which increases restraining power of the differential rotation restraining part between the front wheel and the rear wheel according to occurrence of pitching behavior of the vehicle.SELECTED DRAWING: Figure 4
【課題】簡単な構成により車体のピッチング挙動を抑制する車体挙動制御装置を提供する。【解決手段】車輪RWを車体Bに対してバウンド方向及びリバウンド方向にストローク可能に支持するとともに、ストロークに応じて車輪の中心Cがホイールベースを伸縮する方向へ変位するジオメトリを有するサスペンション装置210と、前輪FWへ駆動力を伝達する前輪駆動力伝達機構30と後輪RWへ駆動力を伝達する後輪駆動力伝達機構50との差回転を拘束する前後輪差回転拘束部40とを有する車両1に設けられる車体挙動制御装置を、車体のピッチング挙動の発生に応じて前後輪差回転拘束部の拘束力を増加させる前後輪差回転拘束制御部130を備える構成とする。【選択図】図4
