Embodiment Construction

[0029] figure 1 A motor vehicle is shown with a drive 2 , a clutch 3 , a clutch actuator 4 and a transmission 5 . Depending on the configuration of the drive train, this can be a motor vehicle 1 with an automatically shifted transmission, in which case a transmission actuator can also be provided. Alternatively, vehicles with so-called electronic clutches may be involved. A clutch pedal 6 is then also provided, the position of which is detected by a sensor 7 . The signal of sensor 7 is used here to control clutch actuator 4 .

[0030] The control device 8 is only schematically shown. It is connected to the sensor 7 and the clutch actuator 4 and optionally to further sensors. In particular, the control device 8 can acquire the operating parameters 12 from any sensors 9 or from data on the memory 10 . A control variable 14 can then be determined as a function of the at least one operating parameter 12 , on the basis of which the clutch actuator 4 is operated. Although the ...

Abstract

The present invention provides a failure prediction system of a controller which is equipped with a manufacturing information of a machine on which the control device is installed based on error information including correctable error contents and ID of the control device which are generated by the control device constituting the failure predicting system, And the control device belongs to a control device group which is constituted by a control device which does not generate the error indicated by the error information.

Description

technical field [0001] The invention relates to a method for operating a clutch actuator in a drive train of a motor vehicle. Background technique [0002] It is known to actuate clutches in motor vehicles by means of clutch actuators. This is the case, for example, in automatic transmissions or in motor vehicles with so-called electronic clutch actuation systems. In this case, unlike an automatic transmission, a clutch pedal is also provided, wherein the clutch pedal has a position sensor for detecting the position of the clutch pedal. However, the actuation of the clutch is no longer directly via the movement of the clutch pedal but by means of a clutch actuator. [0003] The clutch actuators used here can be configured in different ways. All have in common the electric motor as the drive unit. Its torque is used to operate the clutch. The structure following the electric motor can be very different. In this case, the clutch actuator is referred to as an electrohydra...
