STEUERUNGSVERFAHREN ZUM GANGSCHALTEN IN EINEM DOPPELKUPPLUNGSGETRIEBE MIT AUTOMATISIERTER HANDSCHALTUNG |
摘要 |
<p>A control method of shifting gear in an automatic manual transmission (6) having a twin-clutch gearbox (7) to pass from a current gear (A) to a successive gear (B); the control method provides the steps of: receiving a command of gear shifting; opening a first clutch (16A) associated with current gear (A); closing a second clutch (16B) which is associated with successive gear (B) and starts transmitting a torque after a delay time interval (TR) from the start of the closing; and starting the opening of first clutch (16A), thus decreasing the torque transmitted by first clutch (16A) itself before second clutch (16B) starts transmitting a torque, such that first clutch (16A) decreases the torque transmitted to the driving wheels (3) before the second clutch (16B) starts transmitting a torque to the driving wheels (3).</p> |
