    • Large torque variation is suppressed by preventing the rapid connection (engagement) of an input clutch when a brake is released. When fine adjustment is performed with the use of brake operating means such as a brake pedal, a clutch pressure of the input clutch is varied with high responsiveness to the change of the brake operating means to enable the fine adjustment with high accuracy. Clutch pressure detection means detects a clutch pressure of the input clutch. A controller serving as determination means determines whether or not a rising speed of the clutch pressure of the input clutch is less than a limit rising speed of the original pressure. A controller serving as original pressure control means adjusts the original pressure such that a difference between the original pressure and the detected clutch pressure of the input clutch becomes a predetermined offset pressure when it is determined that the clutch pressure rising speed of the input clutch is less than the original pressure limit rising speed, and adjusts the original pressure such that the original pressure is raised at the original pressure limit rising speed when it is determined that the clutch pressure rising speed of the input clutch is equal to or higher than the original pressure limit rising speed.
    • 当制动器被释放时,通过防止输入离合器的快速连接(接合)来抑制大的扭矩变化。 当使用诸如制动踏板的制动操作装置进行微调时,输入离合器的离合器压力随着制动操作装置的变化的高响应性而变化,从而能够高精度地进行微调。 离合器压力检测装置检测输入离合器的离合器压力。 用作确定装置的控制器确定输入离合器的离合器压力的上升速度是否小于原始压力的极限上升速度。 用作原始压力控制装置的控制器调节原始压力,使得当确定输入离合器的离合器压力上升速度较小时,原始压力和输入离合器检测到的离合器压力之间的差异变为预定的偏移压力 并且当确定输入离合器的离合器压力上升速度等于或高于原始压力时,调节原始压力使得原始压力在原始压力极限上升速度下升高 限制上升速度。
