摘要： The present invention essentially relates to a method for finding a slip point of a hybrid vehicle (1) having an electrically towed rear axle. In said method, the electrical machine (17), when starting the vehicle, is actuated to provide the vehicle drive, the engine (7) being turned off, the clutch (10) being open, and the transmission (8) being in neutral. Once the speed of the main shaft has reached a threshold (K′1), the acceleration of said main shaft is measured and stored as a reference value, and the closing of the clutch (10) is gradually controlled. Once it has been detected that the change in acceleration (ΔWAP/Δt) of the main shaft relative to the reference value has reached a threshold (K′2), the position of the clutch (10) is stored in order to deduce therefrom the position of the slip point (PP).

摘要： It is an object of the present invention to achieve stabilization of clutch transmission torque at the point of half clutch completion during a garage shift upon vehicle start up, and to thereby achieve smooth clutch engagement. In a vehicle power transmission device in which a fluid coupling and a wet friction clutch are provided in series at points on a power transmission path which extends from an engine to a transmission, and which performs engagement/disengagement control of the clutch by varying the pressure of operating fluid used for engagement/disengagement driving the clutch in accordance with duty pulse signals outputted from an electronic control unit, clutch engagement control is begun at the same time as (t1) the transmission is put into gear in a state of clutch disengagement when a vehicle is about to start up from a standstill. When the difference in rotation between the input and output sides of the fluid coupling reaches or exceeds a predetermined value (t3) during this clutch engagement control, a duty Dc corresponding to full clutch engagement is outputted from the electronic control unit.

摘要： A method of learning a kiss point of a first clutch of a dual clutch transmission includes controlling a rotational speed of the input shaft to be within a pre-determined range. When both the first clutch and the second clutch are determined to be disengaged from the input shaft, and the rotational speed of the input shaft is within the pre-determined range, then the first clutch is moved from a disengaged position into an engaged position. An increase in a rotational speed of a first transmission shaft, which is coupled to the first clutch, is detected. When the increase in the rotational speed of the first transmission shaft is detected, a position of the first clutch is identified. The identified position of the first clutch is saved in a memory of a transmission control module as a learned first clutch kiss point.

摘要： When there is a shift command for the transmission (3) during or immediately after clutch touch point learning, a shift operation value for the transmission (3) is reduced compared to what it normally is (steps ST11 and ST12). Reducing the shift operation value in this way enables the change in the rotation speed of an input rotating body at the time of a gear shift operation to be gradual if that gear shift operation is during or immediately after clutch touch point learning. As a result, inertia torque, and thus shift shock, can be suppressed.

摘要： The instant invention relates to a method for determining an application point of an automatically actuated friction clutch of an automatic mechanical transmission for a motor vehicle. According to it, after the pre-selection of a new gear, the clutch automatically separates, the activated gear is disengaged, the engine rotational speed is brought to a target value for the new gear and the clutch with higher advancing speed is advanced to an application point at which the transmission input shaft is precisely entrained. To determine the application point, the gradient of the time curve of the rotational speed of the transmission input shaft is monitored, an important change of the gradient that adjusts itself when reaching the application point is determined and the position of the clutch existing at this moment is defined as application point. The application point is preferably determined during downshifts, the time rotational speed curve of the transmission input shaft has between the slowdown and the re-acceleration a distinct minimum easily and accurately to be determined.

摘要： A method for determining a torque characteristic of a friction clutch located in a drive train of a motor vehicle in the force flow between a drive engine and a transmission and which is closed in its rest position. At least two marker points of a regulating-path-dependent torque characteristic are determined, one of which is determined at a slipping limit of the clutch. To enhance determination of the torque characteristic, a first marker point is determined with the clutch engaged, the transmission in neutral and the engine running, by slowly disengaging the clutch until a reduction in the speed of the transmission input shaft relative to the engine speed is detected. A corresponding pair of values of this marker point with the known braking torque of the input shaft and the set position are used for adapting an existing characteristic.

摘要： A method and a device for controlling a clutch, for example an automatic friction clutch forming part of a drive train of a motor vehicle, for a torque transfer between an engine and a transmission, with the clutch having significant clutch way points assigned to it. For achieving the operational readiness of the clutch over the shortest possible time period, whereby an accurate clutch adjustment is still guaranteed, a clutch way point coordinate system is monitored by checking the point of engagement of the clutch, established through a learning process and having at least a relevant clutch way point for the starting procedure. In case of any recognized change(s), the clutch way point is suitably corrected or otherwise used as is.
