摘要： A steady voltage is generated which is proportional to the quotient of the rotational rates of the two members for which it is desired to determine the slip rate. The apparatus may be used to effect coupling of the two members when the slip rate falls to or very near zero, particularly in a motor vehicle transmission. The control voltage is generated by first generating, through electrical sensors and circuits, a train of pulses having a repetition rate proportional to the rotational rate of one of the members and having a pulse width inversely proportional to the rotational rate of the other of the members, and then integrating the pulse train to provide a steady control voltage.

摘要： A clutch control device is provided for a four-wheel drive vehicle for transmitting drive force to the rear wheels. The clutch control device includes a dog clutch and a friction clutch, and a controller that controls the engagement and disengagement of the dog clutch and the friction clutch. In this clutch control device, when there is a request to engage the dog clutch from a disengaged state, the controller, during the engagement control of the friction clutch, first controls the engagement of the friction clutch, monitors the change gradient of the clutch rotational speed difference of the dog clutch and starts engagement of the dog clutch upon determining that the gradient of the clutch rotational speed difference is no longer decreasing.

摘要： A method for adjusting the point of engagement of a friction clutch of a step-variable transmission for a motor vehicle, in particular a friction clutch of a dual clutch transmission. The friction clutch is controllably actuated by means of a clutch actuator and at least one synchronizer shifting clutch is controllably actuated by means of a shift actuator for the engagement and disengagement of a gear ratio of the spur-gear transmission. A set-point of the clutch actuator for the point of engagement of the friction clutch is adjusted as a function of a speed gradient value, which ensues from a transitional state with the friction clutch actuated and the shifting clutch actuated, once the shifting clutch is opened. The transitional state is established by setting the clutch actuator and the shift actuator to a respective transitional value substantially at the same time or, at least in sections, in parallel.

摘要： A transmission control device includes even-numbered and odd-numbered transmission gears selected via a shift mechanism and causes the torque capacities of two clutches to be transitioned to a certain proportion until the clutch rotation speed difference of a low-speed gear-side clutch reaches 0 or approximately 0, sets the torque capacity of the clutch on the low-speed gear side to be the total torque capacity of both clutches, and sets the torque capacity of the clutch on the high-speed gear side to 0. The heat load on the clutch at the time when the vehicle starts to move is reduced and the durability thereof is improved, and the clutch can be made smaller and lighter.

摘要： In a process for regulating a clutch which is situated within a power train between an input shaft (22) and an output shaft (24), the rotation-rate differences .DELTA..omega. of the power train are detected via a sensor device. With the use of regulating equipment and depending on a control variable x, a correcting variable y which affects the speed difference .DELTA.n is controlled. To provide regulating equipment at favorable construction cost, the regulating equipment has a comparator unit (51) in which an actual value x of the rotation-rate difference .DELTA..omega. in the power train behind the clutch (21) is compared with a preset fixed limited value w.sub.const, the rotation-rate difference .DELTA..omega. being limited to the limit value w.sub.const by changing the correcting variable of the clutch (21) upon reaching or exceeding the limit value w.sub.const.
