摘要： PROBLEM TO BE SOLVED: To make an optimum disengage control of a transmitted torque changing mechanism in accordance with the vehicle operating situation. SOLUTION: The control amount per unit time when the transmitted torque changing mechanism is disengaged after the speed change is ended, is decided or changed in accordance with the vehicle operating condition. When changing-over is made from the torque transmission by the transmitted torque changing mechanism (for example, assist clutch) into the torque transmission by a meshing type transmitting mechanism after the speed change, a step in the torque may generate a torque vibration in the transmission output, depending upon the control of the transmitted torque changing mechanism. At this time, the degradation of the shift feeling owing to the axial vibration when the speed change is ended, is suppressed by deciding or changing the control amount so that the disengagement takes place gradually according to the vehicle operating condition. The speed of disengagement is adjusted according to the vehicle operating condition, for example the calorific value of the transmitted torque changing mechanism. This suppresses the generated calorific value of the transmitted torque changing mechanism to lead to enhancement of the durability. COPYRIGHT: (C)2005,JPO&NCIPI
摘要翻译：要解决的问题：根据车辆操作情况进行传动转矩改变机构的最佳分离控制。解决方案：根据车辆运行条件决定或改变在变速结束之后传递的扭矩改变机构分离时的每单位时间的控制量。当通过转换变速机构（例如辅助离合器）通过啮合型变速机构在变速后的转矩传递中进行转矩变换时，转矩阶段可能产生转矩振动传输输出，取决于传输的扭矩变化机构的控制。此时，通过决定或改变控制量来抑制由于变速结束时的轴向振动引起的换档感觉的劣化，使得根据车辆操作条件逐渐发生脱离。根据车辆的运行状态，例如传递的转矩变更机构的发热量来调整分离速度。这抑制了传递转矩变化机构的产生的热量导致耐久性的提高。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To resolve a problem of shortening a service life of an assist clutch when a difference between an input shaft rotational frequency and a target input shaft rotational frequency after a lapse of a predetermined time from an assist clutch operation start is a predetermined value or more for every gear change, and gear change using the assist clutch is carried out continuously. SOLUTION: The number of gear changes after assist clutch disengagement is counted, and when the count reaches a predetermined value or more, posterior gear change using the assist clutch is stopped on the basis of a state of the assist clutch. When the predetermined time has passed from the assist clutch operation start, the input shaft rotational frequency does not match the target input shaft rotational frequency, and gear change control cannot move onto a next phase, gear change is carried out without using the assist clutch and wear of the assist clutch is suppressed.
