    • A fluid pressure cylinder (3) is connected to a discharge port (24) of a fluid pressure pump (2). A suction port (25) of the fluid pressure pump (2) is connected to a tank (10) via a suction passage (11) in which a flow restrictor (15) is provided. A change-over valve (4) changes over operation modes of the fluid pressure cylinder (3) between a load mode in which the pressure cylinder (3) is driven by the fluid pressure pump (2) and an unload mode in which the fluid pressure cylinder (3) elongates and contracts according to an external force exerted thereon in response to a differential pressure between the discharge port and the suction port. Automatic change-over of the operation modes of the pressure cylinder (3) in response to an operation of the fluid pressure pump (2) is thereby realized.

    • A torque converter lockup capacity control device is configured to conduct coast-time lockup control during coast-running in order to prevent engine stall, shock from occurring in the output shaft of a transmission due to lockup when a driver releases an acceleration pedal and the running condition switches from a drive running condition to a coast-running condition. Torque converter lockup occurs because the engine output torque drops from a time on when the throttle opening degree becomes zero. Thus, during a period from the time on until fuel cut-in at time, the lockup capacity is lowered to a minimum capacity corresponding to a standby pressure and lockup is avoided. The lockup capacity is raised to a larger value from the predetermined time on, and ordinary coast-time lockup control is executed.
    • 变矩器锁定能力控制装置被配置为在滑行运行期间进行惯性停车控制,以防止发动机停止,当驾驶员释放加速踏板时由于锁定而在变速器的输出轴中发生冲击,并且运行 条件从驱动器运行状态切换到沿岸运行状态。 发生扭矩转换器锁定,因为发动机输出扭矩从节气门开度为零时开始下降。 因此,在从时间到直到燃料切断的时间段内,锁定能力降低到对应于待机压力的最小容量,并且避免了锁定。 从预定时间开始将锁定容量提高到更大的值,并且执行普通的惯性停车锁定控制。
