    • PROBLEM TO BE SOLVED: To suppress generation of abnormal sound from a transmission mechanism when turning a vehicle. SOLUTION: A front wheel output shaft is directly connected to the transmission mechanism, while a rear wheel output shaft is connected to the transmission mechanism via a transfer clutch. When vibration appears in the number Nf of rotation of the front wheel output shaft (a code γ2) in a state in which the number Nf of rotation of the front wheel output shaft and the number Nr of rotation of the rear wheel output shaft are diverged to be more than a prescribed value by turning traveling (a code α2) and engine speed Ne and the number Nt of rotation of a turbine are made closer to be lower than the prescribed value by releasing an accelerator pedal (a code β2), a duty ratio Rd of a clutch pressure control valve is reduced (a code δ2). When it is decided that the vibration of the number Nf of the rotation of the front wheel output shaft disappears according to the reduction of the duty ratio Rd (a code ε2), a slip control is returned to a normal slip control and the duty ratio Rd is controlled to be raised again (a code ζ2). As a result, the vibration of the front wheel output shaft is suppressed and the generation of abnormal sound from the transmission mechanism can be suppressed. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:为了在转动车辆时抑制来自变速机构的异常声音的产生。 解决方案:前轮输出轴直接与传动机构连接,而后轮输出轴通过传动离合器与传动机构连接。 在前轮输出轴的旋转次数Nf和后轮输出轴的转数Nr发生变化的状态下,当前轮输出轴(代码γ2)的旋转数Nf出现振动时 通过转动行驶(代码α2)和发动机转速Ne和涡轮机的旋转数Nt使得通过释放加速器踏板(代码β2)而使其更接近于低于规定值的规定值, 离合器压力控制阀的占空比Rd减小(代码δ2)。 当根据占空比Rd(代码ε2)的减小确定前轮输出轴的旋转数Nf的振动消失时,滑差控制返回到正常滑差控制,占空比 Rd被控制为再次升高(代码ζ2)。 结果,能够抑制前轮输出轴的振动,能够抑制来自变速机构的异常声音的产生。 版权所有(C)2009,JPO&INPIT
