Description

The invention relates to a method for controlling an automated vehicle transmission.

The invention further relates to a device for controlling an automated vehicle transmission.

From the DE 197 29 251 A1 a method for detecting a spontaneous dynamic demand of a driver of a motor vehicle is known, wherein an extent of the operation of an actuator designed as an accelerator pedal is compared with a threshold value and wherein the dynamic demand is detected when the amount is above a certain threshold. When comparing the extent with the threshold, it is considered how the driver normally operates the actuator.

Furthermore, from the EP 0 872 670 A2 a servo-circuit control system for controlling an operation of a servo circuit is known, which receives a switching operation in a respective direction from a shift lever via a shift cable and the switching operation with a force amplified by a motor of the servo circuit power to a transmission. The servo-circuit control system is configured such that a shift operating force is transmitted to the engine via a motor drive portion in the opposite direction to the shift direction when a shifted speed change stage detected by a shift position sensor and a select sensor is not in a possible downshift speed change number range.

The DE 60 2004 004 617 T2 describes an operating position selector for an automatic transmission whose operating modes are switchable. The operating position selecting means comprises a selector lever unit having a selector lever operated by a driver between a plurality of positions corresponding to the operating modes. Further, an operating position sensor is provided which detects an operating position of the selector lever and outputs an operating position signal. A mode switching unit is attachable to the automatic transmission to switch operating modes of the automatic transmission. In addition, a mechanical connecting means is provided which mechanically connects the selector lever and the mode switching unit. An auxiliary actuator is disposed between the selector lever and the mode switching unit and provides an assisting power to the selector lever. An operating speed detector is provided for detecting the operating speed of the selector lever. A control unit controls the auxiliary operating member on the basis of the operating position signal, the control unit having a large-movement preventing member which prevents the selector lever from moving beyond a desired selecting position by decreasing the assisting force when the operating speed outputted from the operating speed detector is one Speed limit exceeded.

The invention is based on the object of specifying a method and a device for controlling an automated vehicle transmission.

With regard to the method, the object is achieved by the features specified in claim 1 and in terms of the device by the features specified in claim 3.

Advantageous embodiments of the invention are the subject of the dependent claims.

In a method for controlling an automated vehicle transmission, an actuation speed of a control element provided for a manual shift operation is determined according to the invention, and a switching behavior of the vehicle transmission is set as a function of the actuation speed.

In this way, it is achieved in a particularly advantageous manner that a driver of the vehicle can directly influence the switching behavior of the vehicle transmission by the actuation speed, without additionally requiring the choice of a driving mode. Thus, for example, at high operating speeds a sporty and fast switching behavior can be set, at low operating speed, however, a comfortable and slow switching behavior.

Embodiments of the invention will be explained in more detail below with reference to a drawing.

Showing:

1 schematically a block diagram of a device according to the invention for controlling an automated vehicle transmission.

In the only one 1 is a block diagram of a possible embodiment of a device according to the invention 1 for controlling an automated vehicle transmission 2 with two electrical controls 3 . 4 to perform a manual shift. At the controls 3 . 4 each is in particular one on a steering wheel of a vehicle or on a steering column in the region of the steering wheel arranged rocker switch, which is also referred to as Schaltpaddle. Here, for example, a first rocker switch is designed such that in their manual operation, a gear or a gear is switched back. A second rocker switch is designed, for example, such that when it is manually operated, a gear or a gear step is upshifted.

Furthermore, a determination unit 5 for determining an actuation speed v of the operating elements 3 . 4 provided during their manual operation. The determination unit 5 is with a control unit 6 coupled, by means of which, depending on the operating speed v switching behavior of the vehicle transmission 2 is set.

For determining the actuation speed v, the determination unit comprises 5 in a manner not shown for each control 3 . 4 two switching elements, wherein in each case a first switching element in an unactuated initial position of the respective operating element 3 . 4 and a second switching element in an actuated end position of the respective operating element 3 . 4 is pressed. From a determined during the operation period between the initial and final position, the operating speed v is determined.

Alternatively or additionally, the determination unit comprises 5 for each control 3 . 4 in a manner not shown, a displacement sensor for detecting a path of the respective control element 3 . 4 between the starting position and the end position, wherein the operating speed v is determined on the basis of the path and the time.

Depending on the determined operating speed v, the switching behavior of the vehicle transmission 2 set. In this case, in particular, an automatic clutch actuation, a switching time and / or an intermediate gas function are set variably. For example, in a quick operation of the controls 3 . 4 a clutch change purely hydraulic, whereby a sporty switching behavior is generated.
