    • PROBLEM TO BE SOLVED: To carry out shift disengagement at proper timing in upshift gear change in a vehicle mounted with an AMT automatically carrying out shift engagement operation and shift disengagement operation by an actuator. SOLUTION: After there is an upshift gear change demand, when torque of an input shaft side of a transmission matches torque of an output shaft side of the transmission for the first time, or when force of torsional vibration is minimum (a point P1), by controlling shift disengagement operation such that the transmission becomes a shift disengaged state, torsional vibration is prevented. By such control, stagnation of a shift stroke can be suppressed, and shift disengagement can be smoothly carried out at proper timing. By this, an excessive shift disengagement load is not applied to the transmission, and a load to the transmission can be reduced. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:在安装有AMT的车辆的换高档换档中,在适当的时间进行换档脱离,自动执行换档接合操作和由致动器进行换档分离操作。 解决方案:在需要换档换档要求之后,当变速箱的输入轴侧的扭矩首次与变速箱的输出轴侧的转矩匹配时,或扭转振动力最小时(一点 P1),通过控制换档脱离操作使得变速器变为换档脱离状态,防止扭转振动。 通过这样的控制,可以抑制换档行程的停滞,并且可以在适当的时机平稳地执行换档脱离。 由此,不会对变速器施加过大的换档脱离负荷,能够降低对变速器的负荷。 版权所有(C)2010,JPO&INPIT
