Abstract: The invention relates to a method for adapting the kiss point of at least one of the clutches (K1 and/or K2) of a double clutch (1) of a double clutch transmission (2) of a motor vehicle (3), in particular of the double clutch (1) of an automated double clutch transmission (2), wherein the kiss point of that clutch (K1 or K2) is adapted which is assigned to the transmission input shaft (4 or 5) of the free component transmission of the double clutch transmission (2), wherein the engine rotational speeds (n
M ) are determined and the synchronous rotational speeds (n
sync1/2 ) of the transmission input shaft (4 or 5) which is assigned to the free component transmission are known or determined, wherein the rotational speeds (n
GE ) of the transmission input shaft (4 or 5) which is assigned to the free component transmission are detected, and wherein the clutch (K1 or K2) to be adapted is first of all opened completely. The accuracy of the determination of the kiss point is achieved by virtue of the fact that the gears which are assigned to the free component transmission and/or the synchronizing devices which are assigned to the free component transmission are disengaged or opened, and that subsequently first of all determination and/or evaluation takes place of the drag torques which possibly act in an accelerating or retarding manner on the transmission input shaft (4 or 5).

Abstract: A method of calibrating the control current start-up threshold in a proportionally controlled drive system (11) for a work vehicle (10) is disclosed. To determine a current threshold value for use in the system (11) a control current (IC1/IC2) exhibiting a relatively low value is first applied to the system. Subsequently, the steps of repetitively increasing the control current to a control current start value at which system motion starts and decreasing the control current to a control current stop value at which system motion substantially stops are repetitively conducted. The resultant control current start values and control current stop values are stored in a memory (117). The stored control current start values and control current stop values are then averaged to determine a control current threshold value for use in controlling the system.

Abstract: A method for automatic control of a friction clutch (1) in a vehicle, which clutch is designed to be disengaged and engaged by a clutch actuator (3) under automatic control. An initial partially engaged clutch stroke position (Q1) and an initial clutch stroke position (P1) at which fluid pressure in the clutch actuator reaches a prescribed value are detected to obtain a difference (R1) between said two clutch stroke positions prior to initiation of automatic clutch control. The friction clutch wears as it is used. Therefore, both of the partially engaged clutch stroke position and the clutch stroke position attaining the prescribed fluid pressure value change while the automatic clutch engagement/disengagement control is being performed. However, the difference between these two clutch stroke positions does not change. A current clutch stroke position attaining the predetermined fluid pressure is only detected during the automatic clutch control, and a current partially engaged clutch stroke position (Q2) is determined by adding the difference (R1) to the detected clutch stroke position (P2).

Abstract: A vehicle clutch engagement position is disclosed wherein the clutch is moved, under computer control, at a constant rate, from a disengaged position toward a fully engaged position while the transmission is in neutral gear, and the position of the clutch is detected at first and second times (T1 and T2). Time T1 corresponds to the time when the detected speed of the transmission input shaft is just above the dropout speed of the input shaft speed sensor. Time T2 corresponds to the time when the detected speed of the input shaft is close to engine speed. The position of the clutch corresponding to the incipient torque point is extrapolated by subtracting an offset amount from the position detected at time T1. The offset is equal to the change in position from T1 to T2 multiplied by the square root of the ratio of the input shaft speeds at T1 and T2.

Abstract: In a method for correcting clutch data used for controlling the engaging/disengaging operation of a friction type vehicle clutch (3), the meet position data among the clutch data is updated by a learning operation at each operation of a predetermined operation member (21a) of the vehicle, and the updated meet position data is corrected in accordance with the engine speed during the actual operation of the clutch (3), each time the vehicle is driven off, whereby appropriate correction of the clutch data can be carried out at a suitable time intervals.
