Abstract: An automatic transmission includes a main transmission and an auxiliary transmission. The auxiliary transmission includes an auxiliary-transmission-side planetary gear mechanism, a first clutch, and a second clutch. The auxiliary-transmission-side planetary gear mechanism is provided between a pair of main-transmission-side planetary gear mechanisms, and a part of the auxiliary-transmission-side planetary gear mechanism is located within the main transmission. The first clutch fixes rotation of a sun gear of the auxiliary-transmission-side planetary gear mechanism. The second clutch connects a ring gear of the auxiliary-transmission-side planetary gear mechanism with the sun gear.

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。
