Patent number: 8924114Abstract: When there is a curve in a forward driving path of a vehicle, a wheel clutch for a turning outer wheel of a rear shaft is engaged and a wheel clutch for a turning inner wheel of the rear shaft is disengaged during driving of the curve. When there is no curve, both of the right and left wheel clutches are engaged when it is estimated the vehicle receive a predetermined disturbance input during forward driving. Then, a target yaw moment of a vehicle is calculated. If an average speed of the right and left wheels of a front shaft is more than the speed of the turning outer wheel, the wheel clutch for the turning outer wheel is engaged when the target yaw moment is applied to the vehicle, so that the engaging force of a transfer clutch is controlled based on the target yaw moment.Type: GrantFiled: September 18, 2013Date of Patent: December 30, 2014Assignee: Fuji Jukogyo Kabushiki KaishaInventors: Koji Matsuno, Shiro Ezoe, Hajime Oyama, Yuichirou Tamura, Takeshi Terazawa, Akihiro Watanabe
