摘要:
A method and a device for controlling starting, driving and shifting processes of a motor vehicle with a drive motor (2) and a gearshift (6), which can be brought into effective drive connection with one another using a starting and shifting clutch (4), with a clutch actuation device (25, 26) as well as with a control apparatus (13) which stands in connection with a power element of the same for controlling the power of the drive motor (2), and which is connected using signal engineering with sensors (14, 17, 19, 21) which ascertain an accelerator deflection angle (A), a motor rotational speed (C) and a transmission input shaft rotational speed (E).
摘要:
A method for detecting a rotational direction of the secondary side of a starting clutch in a motor vehicle string comprising the steps of determination of the primary speed of rotation of the primary side and of the secondary speed of rotation of the starting clutch. If the secondary speed of rotation is greater than the primary speed of rotation, an actuator operates in a closing direction, whereby the degree of closure of the starting clutch is adjusted to be dependent upon the acceleration of the secondary speed of rotation. A specified value for a rotational speed of the driving motor is produced which represents the secondary speed of rotation. To the extent that this value exceeds the value of the primary rotational speed, the rotational speed of the motor is regulated to the specified value. If the primary and secondary rotational speeds are equivalent within a preselected period of time, then detecting the same rotational direction for the primary and secondary sides of the starting clutch. If the rotational speed of the primary side of the starting clutch lies below the idling speed of rotation, detecting different rotational directions for the primary side and the secondary side of the starting clutch.

A device for the control of an automatic motor vehicle clutch is arrayed between an engine and a geaar box and acts primarily as a start-up clutch. A control device receives an electric signal coming from an electronic control device and transforms it into a control quantity for an actuator which engages and disengages the clutch. The engagement of the clutch at start-up occurs with a basic clutch-in speed dependent upon the positioning of the gas pedal and initiated by this positioning and is determined as an electric signal by an electronic control device. For this purpose, a characteristic curve which was determined specifically for the engine is stored in the memory of the electronic control device so that in dependence on the displacement angle of the gas pedal the basic clutch-in speed can be determined very quickly and in a simple manner. It is possible to further improve the quality of the clutch-in process by means of correction factors which are multipliers for the basic clutch-in speed. The highest requirements of a clutch are satisfied when, shortly before reaching the point of synchronization, the clutch is displaced once more in direction of disengagement, whereby the moment of disengagement as well as the disengagement speed are likewise determined by characteristic curves.
摘要:
A motor-vehicle clutch assembly including a start-up and shifting clutch arranged between the driving engine and the gearbox, selectively engaged therebetween by the clutch controlled by an electronic control device and by a complex actuating unit arranged on the clutch. The complex actuating unit consisting of an actuating cylinder for a clutch release lever, several, solenoid valves controlling the auxiliary power and a travel-measuring device. The unit is provided with a singly detachable connection for the pressure supply and for the connection with the electronic control device and the power source, only one plug junction is provided.
