    Abstract: In a coasting control process, an ECU increases line pressure PL of a hydraulic path to predetermined pressure P1 such that discharge pressure of an MOP becomes higher than that before a C1 clutch is disengaged at timing when an executing condition of coasting control is satisfied (time t=t1). According to such coasting control process, driving torque of the MOP increases, so that deceleration (deceleration G) caused by driving of the MOP by a drive wheel becomes larger than that in conventional coasting control in which the discharge pressure of the MOP is not increased. As a result, it is possible to inhibit a driver from feeling discomfort due to free-running feeling generated during the coasting control.

    Abstract translation: 在惯性控制过程中,ECU将油压路径的管路压力PL提高到规定压力P1,使得在满足滑行控制的执行条件的时刻,MOP的排出压力高于C1离合器分离时的排出压力(时间 t = t1)。 根据这种滑行控制处理,MOP的驱动转矩增加,由驱动轮驱动MOP引起的减速度(减速度G)大于MOP的排出压力不增加的现有的惯性滑动控制 。 结果,能够抑制驾驶员由于在滑行控制期间产生的自由行驶感觉而感到不适。

    Abstract: An assembly for driving a friction clutch, having a hydraulically driveable stepped piston, with: a pump driving the stepped piston, which has a working piston moveably arranged in a working chamber that divides it into first and auxiliary working chambers. The working piston is mechanically connected to an auxiliary working piston and hydraulically driveable via a second working chamber. A control valve is arranged between the stepped piston and pump. A first line path leads from the pump to the second working chamber, and a second line path leads from the pump to the first working chamber. The stepped piston has a working tappet which acts on the friction clutch. The first and second line paths are connected via a first line section of the supply line and a multi-port control valve, which has two valve positions, and the first line section is at least partially blocked in one valve position.
