Problems solved by technology

[0016] All hitherto known systems exhibit the following disadvantages: that is, they can only work with a relatively large minimum slip speed of more than 50 r / min
In this case, the speed regulation is carried out so late that undesired excessive oscillations occur in the torque on the output side and in the transmission

Embodiment Construction

[0218] The torque transmission system 10 shown in FIGS. 1a and 2 comprises a torque converter 11 and a clutch clutch 12 which operates by the flow pressure method and which is bridged by the torque converter. The torque transmission system is connected to an internal combustion engine not shown via a shaft 13, which is only schematically indicated, and on the other side, the driven side, via a driven shaft 14 and a drive chain placed behind it. The automatic transfer mechanism connected and driven, the transfer mechanism is also not drawn.

[0219] As shown in Fig. 2 , the half-section principle diagram of the torque transmission system 10 and the pressure control principle diagram together, the torque converter 11 is equivalent to a conventional hydraulic torque converter. This hydraulic torque converter 11 is by a torque converter cover 16 that is connected with the driven device of internal combustion engine, a pump wheel 17 that forms torque converter housing together with...

Abstract

A method of monitoring a torque transmission system with a manually switchable gearbox in the power train of a motor vehicle involves the utilization of at least one sensor unit at the input side of the torque transmission system to ascertain relevant positions of the shift lever of the gearbox and the driving torque of the engine of the motor vehicle. The thus obtained shift lever signals are memorized, together with comparison signals which are obtained as a result of filtering of the shift lever signals, and various characteristics of such signals are recognized and identified to indicate the intention of the operator of the vehicle regarding the switching of the gearbox. The thus obtained switching intention signals are transmitted to a controlled clutch operating system.

Description

[0001] This application is a divisional application whose original application number is 95102116.8, the application date is February 23, 1995, and the title of the invention is "Method for Controlling Torque Transmission System". technical field [0002] The present invention relates to a method for controlling a torque transmission system operatively coupled to a driven device of a drive unit, generally an internal combustion engine, and in driving connection with an automatic transmission via a driven shaft. The system has a torque converter and a friction clutch arranged in parallel with it, a test value detection system and a central computer unit, where the loading force of the friction clutch, and thus the torque transmitted by the clutch, is in It can be purposefully changed under the cooperation with the central computer. [0003] In addition, the present invention also relates to a clutch for a torque converter of the above-mentioned torque transmission system, where...
