Title:
車両の駆動力伝達制御装置
Document Type and Number:
Japanese Patent JP4309089
Kind Code:
B2
Abstract:
A center differential limiting control unit (40), calculates and sets a vehicle speed, a target difference in a rotational speed between front and rear axle shafts (13FR,13FL,13RR,13RL), a control start difference in the rotational speed, and an actual difference in the rotational speed, respectively. Then, when the actual difference is large than the control start difference, it is determined that a front and rear axle shaft control start condition is established, and front and rear axle shaft differential limiting torque is calculated according to the actual difference and the target difference. In contrast, when the actual difference is smaller than the control start difference, it is determined that the front and rear axle shaft control start condition is not established, and an integral term in the front and rear axle shaft limiting torque and control is set to 0. With this operation, the occurence of unpleasant noises and vibrations due to the stick-slip of a clutch element is prevented by stably transmitting the torque by using only a state of engagement in a coefficient of dynamic friction by preventing the clutch element from being locked in a coefficient of static friction as much as possible.
