摘要： A method of adapting control of clutches of a double clutch transmission, including: during a shifting process, controlling torque transmittable by an opening clutch and torque transmittable by a closing clutch according to nominal curves; during a shifting process, determining a difference between a nominal value and an actual value; and adapting a nominal curve of at least one of the clutches for a following shifting process by reducing a difference between the nominal value and the actual value.

摘要： A method for diagnosing damage in the shift mechanism of an automatic gearbox, involving at least one of the following steps: (a) determining an actual period needed for synchronizing a gear, comparing the actual period with a setpoint period for synchronizing the gear, and establishing whether the shift mechanism is damaged; the shift mechanism is assumed to be damaged if the actual period differs from the setpoint period; (b) moving a shift actuator to a limit stop after selection of a gear, establishing whether the limit stop that has been reached is an internal limit stop of the shift actuator or a gearbox limit stop, and establishing whether the shift mechanism is damaged; the shift mechanism is assumed to be damaged if the limit stop that has been reached is an internal limit stop of the shift actuator; (c) determining an actual engine speed during the overlap phase and comparing the actual speed with a speed range within which the engine speed is expected to lie during the overlap phase, and establishing whether the shift mechanism is damaged; the shift mechanism is assumed to be damaged if the actual speed is not within the range for the expected speed.
摘要翻译：一种用于诊断自动变速箱的换档机构中的损坏的方法，其涉及以下至少一个步骤：（a）确定用于使齿轮同步所需的实际周期，将实际周期与用于同步齿轮的设定周期进行比较，以及确定换班机制是否受损; 如果实际周期与设定值周期不同，则假定换档机构损坏; （b）在选择齿轮之后将换档执行器移动到限位挡块，确定到达的限位挡块是否是变速执行器的内部限位挡块或齿轮箱限位挡块，并确定换挡机构是否损坏; 如果达到的限位挡块是换挡执行器的内部限位挡块，则假定换挡机构损坏; （c）确定重叠阶段期间的实际发动机转速，并将实际速度与发动机转速预期在重叠阶段期间所处的速度范围进行比较，并确定换档机构是否损坏; 如果实际速度不在预期速度的范围内，则假定换档机构被损坏。

摘要： A powershift transmission is proposed using two transmission paths, a friction clutch being assigned to each transmission path and the transmission paths being coupleable to an output shaft for torque transmission. The transmission has a device that detects the clutch torque transmitted by the friction clutch of the active transmission path, which is coupled to the output shaft, and, when the clutch torque falls below threshold value, initiates a disengagement of the active gear ratio.
