    摘要： The invention prevents clutch disengagement shock resulting from the sudden release of torsional torque and improves ride-feeling at the time of changing gears or starting at a low-speed gear stage in an automatic clutch vehicle. In a clutch control arrangement for controlling the engagement and disengagement of a friction-type clutch (1) by means of a clutch actuator (3) and a control unit (14), clutch disengagement speed is reduced when, at least, a gear-changing operation by a driver is detected, and the transmission (20) is in a low-speed gear stage. Even when the clutch is automatically disengaged at gear change, since disengagement speed is reduced if the current gear stage is a low-speed gear stage, the clutch (1) is not abruptly disengaged, enabling the prevention of clutch disengagement shock due to the sudden release of torsional torque. Because high torsional torque is normally transmitted to the drive system when either the clutch is in a partly engaged state or the accelerator stroke is large, it is desirable to reduce disengagement speed in these states.

    摘要翻译： 本发明防止了由于突然释放扭转力矩而导致的离合器脱离冲击，并且改善了在自动离合器车辆中在换档时或在低速档位时启动时的乘坐感。 在用于通过离合器致动器（3）和控制单元（14）控制摩擦式离合器（1）的接合和分离的离合器控制装置中，当至少一个齿轮传动装置 检测驾驶员的变速操作，并且变速器（20）处于低速档位阶段。 即使在换档时离合器自动分离，由于如果当前档位是低速档位，分离速度降低，离合器（1）不会突然分离，能够防止由于突然的离合器分离冲击 扭矩释放。 由于当离合器处于部分接合状态或者加速器行程较大时，高扭矩正常地传递至驱动系统，所以期望在这些状态下降低脱离速度。
