    Abstract: A belt-driven continuously variable transmission adapted to prevent an occurrence of belt slippage is provided. The continuously variable transmission comprises a hydraulic actuator formed on a back side of a movable sheave to change a belt groove between a fixed sheave and a movable sheave, and a torque cam assembly adapted to convert a torque into an axial thrust force by a relative rotation between a pair of cam members contacted to each other. In the belt-driven continuously variable transmission, a piston fitted onto a shaft of the driven pulley while allowing to rotate relatively therewith and to reciprocate thereon is integrated with one of the cam members of driven side and with an output gear for outputting torque of the pulley. The cam member of drive side is fixed in an axial direction on a driven shaft to be rotated integrally therewith.

    Abstract: A control system of a vehicle includes an engine, a continuously variable transmission, drive wheels, a clutch, and an electronic control unit. The electronic control unit is configured to release the clutch and stop the engine when a predetermined execution condition is satisfied during traveling, such that the vehicle performs coasting. The electronic control unit is configured to keep the continuously variable transmission at a speed ratio established at start of the coasting, during the coasting of the vehicle. The electronic control unit is configured to restart the engine that has been stopped and perform downshift of the continuously variable transmission, when a predetermined return condition is satisfied during the coasting. The electronic control unit is configured to engage the clutch after the downshift is started, such that the vehicle returns from the coasting.

    Abstract: A drive device for a vehicle includes a power transmission mechanism configured to transmit power output from an output shaft of an engine mounted in the vehicle to wheels of the vehicle, an auxiliary device, a layshaft disposed on a different axis from the output shaft, and a switching clutch configured to selectively connect one of a first shaft and a second shaft to a third shaft so as to transmit power. The layshaft includes the first shaft, the second shaft, and the third shaft. The first shaft is coupled to the output shaft so as to transmit power. The second shaft is coupled to axles attached to the wheels so as to transmit power. The third shaft is configured to relatively rotate with respect to the first shaft and the second shaft, and is coupled to the auxiliary device so as to transmit power.

    Abstract: A vehicle driving device includes: an engine; a brake booster including a negative pressure chamber, the brake booster amplifying a brake pressure by a negative pressure determined corresponding to a pressure inside the negative pressure chamber; a power transmission clutch disposed between the engine and a driving wheel; and a negative pressure pump configured to drive by using at least one of a torque from the engine and a torque from the driving wheel, the negative pressure pump being configured to vary the negative pressure inside the negative pressure chamber. In the vehicle driving device included in a vehicle that performs freewheeling in a state where the power transmission clutch is released and the engine is stopped, the negative pressure pump includes a control chamber configured to reduce a capacity of the negative pressure pump as a magnitude of the negative pressure inside the negative pressure chamber increases.

    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。
