The control device has a maneuvering actuation element for controlling a maneuvering assistance system. The maneuvering actuation element is a transmission control device of a gear actuation unit of a motor vehicle. The gear actuation unit is activated at an inserted reverse gear stage. An actuating element of the gear actuation unit simultaneously represents the maneuvering actuation element.

Description

The invention relates to a control device with a maneuvering operating element for a maneuvering assistance system of a motor vehicle, according to the preamble of patent claim 1.

The maneuvering of a motor vehicle, for example a car or a truck, in particular with a trailer, places high demands on the driver, especially when reversing. In a trailer trailer this is mainly due to the fact that a vehicle with a trailer during reverse driving is an unstable system, so the trailer tends to buckling quickly, if not constantly counteracted accordingly. In addition, it is initially difficult for inexperienced drivers, that in order to achieve a desired direction of the trailer, the vehicle must first be articulated in the opposite direction, in order to set in this way a certain initial bending angle between the towing vehicle and the trailer.

With the aid of a suitable assistance device in the vehicle, however, it is possible to assist the driver to stabilize a certain desired angle of articulation between the vehicle and the trailer (via a suitable control device) when driving backwards. Likewise, it is possible with the help of such an assistance device, initially a certain desired bending angle between towing vehicle and trailer, and thus specify a desired direction of travel, which is then automatically adjusted by the assistance device - by means of actuatory intervention in the steering angle of the towing vehicle.

To operate such an assistance device, in particular for the initial setting and possibly continuous control of the desired bending angle between towing vehicle and trailer, a shunting control device must be arranged in the interior of the vehicle at a suitable location and within reach of the driver. Since the available space for the arrangement of controls within range of the driver in a vehicle limited and mostly already occupied with various controls, it may be difficult to find a suitable position for such a jogging control device. This is even more so, as such a shunting control device is used only comparatively rarely, namely at most in a reverse drive of the vehicle with trailer.

Since in the known Rangiersteuereinrichtungen usually an electric power steering acts as an actuator, the steering wheel is - due to its rigid coupling with the actuator of the power steering - not available as a control element for the Rangiersteuereinrichtung, since the steering wheel automatically assisted in assisted by the assistance system reverse drive, according to the Actuatorial engagement of the power steering, moving.

For this reason, the turn signal lever has already been proposed and used in the past as an actuator for the Rangiersteuereinrichtung. However, the operation of the maneuvering control device via the turn signal lever is not optimal, since this is in the immediate vicinity of the steering wheel. The driver can therefore come in assisted shunting undesirable in contact with the - turning actuator - steering wheel, which in turn could affect the control of maneuvering by the driver.

From the DE 10 2008 034 720 A1 Furthermore, an assisting device for controlling the direction of travel of a vehicle during reverse travel is known, in which (in the case of reversing) an actuating element for the electrical adjustment of the outside mirror is used to control the maneuvering assistance system.

Actuators for mirror adjustment are usually in the door panel and would therefore in principle far enough away from the steering wheel. However, the Spiegelverstellbetätigung is usually designed as a relatively small actuator, and thus only with one or two fingers to operate, which can be too delicate for a reliable control when Rangierbetrieb. In addition, the Spiegelverstellbetätigung on most vehicles (left-hand drive) is on the left hand of the driver, so the driver would have to control the maneuvering with the left hand, which is the majority of right-handers usually difficult.

With this background, it is the object of the present invention to provide a maneuvering control device with an actuating element for a maneuvering assistance system for a vehicle especially when reversing with a trailer, which allows simple and intuitive operation while using as little installation space as possible within the driver's operating range. and wherein the actuator is also robust and far enough away from the steering wheel. The object of the invention should also be realized with the least possible constructive effort and thus at most low additional costs.

This object is achieved by an actuating device having the features of patent claim 1.

Preferred embodiments are subject of the dependent claims.

In a manner initially known per se, the maneuvering control device according to the present invention is used to control a vehicle maneuvering assistance system, in particular when reversing a trailer with a trailer, and for this purpose comprises a maneuvering control element for manual control of the maneuvering assistance system by the driver.

According to the invention, however, the maneuvering control device is characterized in that the maneuvering operating element is part of the actuation device for the speed change gearbox of the motor vehicle. This advantageously enables an integration of the maneuvering operation with the transmission actuation of the motor vehicle

In other words, in this way, the control for the maneuvering assistance system can be optimally positioned in the vehicle interior with little additional outlay and, accordingly, cost-effectively, but at the same time functionally and ergonomically so that good maneuverability and operation of the maneuvering operation by the driver are ensured. At the same time undesired interference between the maneuvering and the - in assisted maneuvering - actuated moving steering wheel is excluded when maneuvering by means of the invention Rangiersteuereinrichtung due to the usually large distance between the steering wheel and Gangwahleinrichtung.

Furthermore, in most vehicles (left-hand drive) and most drivers (right-handed), the maneuvering operation can now be performed optimally ergonomically with the right hand, with the maneuvering element formed according to the invention as part of the transmission actuation not being below the small size of the prior art as Rangierbetätigung known rearview mirror adjustment suffers.

The invention is first of all realized independently of how the Rangierbetätigungselement is structurally designed and arranged in the transmission actuating device. Furthermore, the invention can also be realized irrespective of whether the transmission actuating device is a transmission actuation for a shift-by-wire-controlled transmission, or a mechanical transmission actuation by means of linkage or cable pull.

In particular, with the background of the use of the Rangiersteuereinrichtung for reversing with trailer is provided according to a particularly preferred embodiment of the invention, however, that the Rangiersteuereinrichtung is only enabled or activated by the engagement of the reverse gear on the gear selector of the transmission.

In this case, the activation or activation of the maneuvering control device when inserting the reverse gear on the gear selector can be done either electronically, mechanically or both electronically and mechanically.

In this way, on the one hand, the legal requirements - for example, with respect to the actuatory design of steering movements - met, and on the other hand can be so avoid operating errors in the form of an unwanted activation of Rangierunterstützung.

With this background, it is provided according to a further, particularly preferred embodiment of the invention that one or the actuating element of the transmission actuating device simultaneously represents the maneuvering actuating element. This initially results in an advantageous multiple use of the corresponding actuating element of the transmission operating device by the corresponding actuating element of the transmission operating device - at the same time forms the actuating element for controlling the Rangierassistenzsystems - in the presence of the corresponding boundary conditions, such as inserted reverse gear. An additional actuating element for the maneuvering assistance system can thus be dispensed with.

This embodiment of the invention can be largely independent of the structural design and arrangement of the Rangierbetätigungselements - or the corresponding Getriebebetätigungselements - realize. According to one possible embodiment of the invention, however, the maneuvering control device comprises a maneuvering lane, wherein the maneuvering lane is formed as an additional tipping lane of the transmission operating device. The additional jogging of the transmission operating device is arranged in the region of the reverse gear.

Preferably, the Rangiertippgasse is arranged substantially transversely to the shift gate of the transmission operation, and the Rangiertippgasse for the Rangiersteuereinrichtung intersects with the shift gate of the transmission operation in the range of the reverse gear of the transmission operation.

In other words, this means that in the area of the reverse gear step of the transmission actuation, an additional tip-off lane is essentially in the vehicle transverse direction. Is at the transmission actuation thus the reverse gear inserted, the driver can by lateral moving the - then in position "R" - shift lever or shunting the Rangiersteuereinrichtung give the desired commands, in particular set an initially desired bending angle between towing vehicle and trailer, or during reversing the respective bending angle between towing vehicle and change trailer by appropriate lateral movements of the selector lever.

According to an alternative embodiment of the invention, the additional Rangiertippgasse is arranged in the region of the reverse drive stage position and substantially parallel to the shift gate, wherein between the reverse drive stage position of the shift gate and Rangiertippgasse a connecting lane is arranged. In this embodiment, the Rangiertippgasse thus substantially corresponds to the arrangement of a conventional jogging for manual gear change in an automated vehicle transmission or automatic transmission. In this embodiment, therefore, the maneuvering control device can be activated in particular by the transmission operating element being moved from the position "R" for the reverse driving step through the connecting lane into the maneuvering lane. Here, too, the activation of the maneuvering control device can thus only take place when the reverse operating gear has already been selected on the transmission operating device.

A further preferred embodiment of the invention provides that the transmission actuating device is formed monostable and has a shift gate and at least one tip-off. In this case, an activation of the maneuvering control device (and the simultaneous deactivation of the transmission actuation) takes place if the reverse gear is engaged in the transmission, and the transmission operating element is moved into the tip-way, or is in the tip-off lane. A (in at least one shift gate) monostable designed transmission actuator is present when the actuator, such as the selector lever automatic transmission is stored or spring loaded so that the selector lever - within at least one shift gate - after each manual deflection of a basic position in at least one further switch position falls back into the normal position as soon as it is released by the driver. An example of a monostable shift gate is the jogging alley that exists in some automatic transmissions.

This embodiment of the invention has the particular advantage that a conventional, monostable transmission operating device with jogging in most unchanged form can also be used to control the Rangierbetätigung. In this case, no functionality of the transmission actuator is lost, since the activation of the manual gear change in the jogging - starting from the reverse gear - is not provided anyway in a pure transmission actuation. Alternatively, however, the jogging path in this embodiment of the actuating device can also be designed as additional jogging alley only assigned to the control of the maneuvering assistance system.

A further embodiment of the invention provides that the transmission actuating device has a preferably multi-stable (ie, a plurality of stable switching positions exhibiting) rotary transmission actuating element.

In this case, the shunting actuating element is formed in this embodiment by a monostable switching element arranged on or on the rotary transmission actuating element. As already described above, the shunting actuating element designed here as a monostable switching element is preferably electrically and / or mechanically locked again as long as the transmission is not in the reverse gear stage or until the reverse gear stage on the gearbox actuating element has been selected.

This embodiment can be realized largely independent of the structural design of the switching element for shunting. Thus, the switching element can be configured for shunting, for example, as a monostable rocker switch, in particular on the z. B. designed as a rotary knob rotary transmission actuator can be arranged. However, the switching element for maneuvering can also be arranged for example as a monostable additional rotary ring or monostable thumbwheel on or on the multi-stable knob of the transmission operation. The arrangement of a joystick for controlling the maneuvering assistance system on the rotary knob of the transmission operation is conceivable and therefore provided in the context of this embodiment of the invention.

A further possible embodiment of the invention consists in a likewise preferably multi-stable rotationally trained transmission actuating element, for example as a rotary knob with stable switching positions, wherein the rotary knob, however, has an additional translational degree of freedom for controlling the Rangierassistenzsystems.

In other words, this means that the rotary knob for selecting the switching stages of the transmission not only multistable several rotational positions corresponding to the gear stages can take, but can also be moved in a monostable translational, for example, transverse to the direction of travel to control in this way when reversing with trailer the Rangierassistenzsystem. Again, the additional translational degree of freedom for controlling the Rangierassistenzsystems is preferably electrically and / or mechanically locked again, unless the reverse gear is selected by means of appropriate rotation of the knob.

According to a further embodiment of the invention, the transmission actuating device has a plurality of keys with which the various transmission drive stages can be selected. The button for selecting the reverse gear is additionally designed as a rocker switch to control the Rangierassistenzsystems.

In this embodiment, there is also a visually particularly clear integration of the control of the maneuvering assistance system in the gear selector of the transmission operation, since the relationship between the inserted reverse gear and the control of Rangierassistenzsystems - visualized by the trained as a rocker switch button for the reverse gear. The rocker switch function of the button for the reverse gear can be carried out alternatively also in the form of additional buttons next to the "R" button of the gear selector of the transmission.

Also in this embodiment, the rocker switch function for controlling the Rangierassistenzsystems for safety reasons preferably as long as electrically and / or mechanically locked, as the transmission is not in the reverse gear, or as long as the button is not pressed for the reverse gear on the Gangwahleinrichtung.

A further embodiment of the invention provides that the transmission actuating device comprises a selector lever for selecting the transmission driving stages, wherein the shunting operating element is formed in this embodiment by an additional monostable switching element arranged on or on the selector lever knob.

In this case, the additional, monostable switching element on the selector lever knob can be designed, for example, as a rocker switch, as a monostable rotary ring, as a switch, button, thumbwheel or lever. The additional switching element on or on the selector lever knob also preferably remains locked or deactivated again as long as the reverse gear is not selected or engaged. However, once the reverse gear has been selected or engaged in the transmission, the control of the Rangierassistenzsystems can be done by the additional switching element on the selector lever knob.

In an alternative embodiment of the invention, the transmission actuating device also comprises a selector lever for selecting the transmission drive stages. In this embodiment, however, the control of the maneuvering assistance system is performed by rotation of the selector lever knob or the entire selector lever.

The rotational mobility of the knob or selector lever is again formed monostable, so that it falls back when releasing its rotational initial position. Again, the additional rotational degree of freedom of the selector lever or selector lever knob preferably remains locked again until the reverse gear is selected at the selector lever. If the selector lever is thus in the "R" position, the maneuvering assistance system can be controlled by means of rotation of the selector lever or selector lever knob.

According to a further embodiment of the invention, it is provided that the transmission actuating device has a monostable selector lever for manual gear selection, wherein the selector lever additionally a multi-stable actuator assembly - for example in the form of buttons or in the form of a knurled wheel - is arranged to select the Getriebefahrstufen. In this case, the control function for the maneuvering assistance system is electrically and / or mechanically released again when the reverse drive stage is selected on the multistable actuating arrangement of the selector lever.

In this case, thus by pressing the monostable selector lever - instead of the manual gear selection in the transmission - a corresponding control of the angle specification between towing vehicle and trailer for the maneuvering assistance system.

A further, particularly preferred embodiment of the invention provides that an electronic computing unit for determining the angle specification for the power steering of the towing vehicle is integrated into the transmission actuating device of the motor vehicle as a function of the relative angular position between motor vehicle and trailer.

This embodiment has the advantage that not only the operation but also the evaluation and electronic control of the maneuvering assistance system can be integrated into the transmission actuation. By thus given double use of both the transmission operating element or selector lever, as well as the selector lever electronics can thus achieve further cost advantages compared to a separately operated maneuvering assistance system with its own, additional controller.

In particular, with the background of the use of the invention in multi-axle trailers - with at least one servo-steered axle - provides a further embodiment of the invention that the Rangierassistenzsystem has an interface for communication with a controller of the trailer. It can be done by the Rangierassistenzsystem - in addition to controlling the power steering of the towing vehicle - and the determination of a desired steering angle for the at least one servo-steered axle of the trailer. This target steering angle can be transmitted to the trailer control unit and used by this to control the steering angle of the steered trailer axle. In this way, maneuvering with multi-axle trailers can be additionally facilitated and stabilized, so that not only the towing vehicle, but also the trailer can be actively controlled in the intended direction.

Preferably, the communication between the maneuvering assistance system and the trailer - z. B. in the form of an extension of the vehicle CAN - on the already existing power supply plug of the trailer, either via a designated communication contact, or by means of signal modulation via one of the existing power contacts of the trailer plug.

In the following the invention will be explained in more detail with reference to exemplary embodiments illustrative drawings. Showing:

13 an actuator of another Rangiersteuerung invention with gear selection by thumbwheel.

1 and 2 show in a highly schematic way a team from a towing vehicle 1 and one to the towing vehicle 1 coupled (here uniaxial) trailer 2 in the plan view.

It will be appreciated that such a combination in reverse driving according to 2 represents an unstable system. This is related to the fact that when reversing a team already a simple curve with a constant radius, for example, according to 2 can only be passed through if the wheels of the steered axle of the towing vehicle are exactly taken so that the towing vehicle 1 taken alone describes a curve with exactly the same radius as the whole team.

At the slightest deviation of this target steering angle on towing vehicle 1 However, the bending angle β of the trailer 2 inevitably continue to increase, so that the trailer crosses after a short time and the Rückwärtsrangieren must fail.

Likewise, based on the 1 and 2 recognizable that the towing vehicle 1 for the initiation of, for example, a right turn according to 2 must first describe an introductory left turn so that the desired bending angle β of the trailer - here to the right - ever sets. Would the driver of the towing vehicle 1 (with the intention of driving backwards in a right-hand turn), steering his steering wheel directly in the direction of the right turn, the trailer would 2 instead, in a left turn corresponding position relative to the towing vehicle 1 emotional. In this case, too Thus, the desired maneuver maneuver would fail after a few meters.

The problem with the Rückwärtsrangieren a team with trailer is thus that the trailer 2 must first be brought by countersteering in the desired direction, and that the - unstable when reversing - trailer then by slight oscillation of the towing vehicle 1 must be kept permanently active on track to the thus set curve radius, so not unlike, for example, when attempting to balance a reversed pendulum on the hand.

The shunting control device according to the invention is thus intended to assist the driver in reversing with a trailer to control or regulate the difficult initial setting during rearward travel and subsequent maintenance of the direction of travel of the entire trailer.

A functional diagram of an embodiment of the shunting control device according to the invention is shown in FIG 3 shown. In 3 are the functionally essential components actuator (power steering), control element (selector lever), sensors (buckling angle sensor) and control unit (Electronic Control Unit) and their interaction shown schematically.

First, the control unit ECU determines the current actual angle between towing vehicle from the signal of the kink angle sensor arranged, for example, on the trailer hitch 1 and followers 2 , At the present invention, the Rangierbetätigungselement comprehensive transmission operation - in the present embodiment, ie by means of the selector lever - is or was set by the driver a certain target angle for cornering.

Subsequently, the control unit ECU determines from the nominal angle and the actual angle the respectively suitable impact of the front wheels of the towing vehicle 1 , In this case, the above-mentioned requirements are taken into account by the control unit ECU, that is, in particular the first required to initiate the curve turning the towing vehicle in the opposite direction as well as the subsequent commuting to the target angle β between trailer 2 and towing vehicle 1 to keep the trailer unstable when reversing on the desired course.

In the 3 only highly schematically illustrated embodiment of the present invention has the particular advantage that not only according to the invention the operation of the maneuvering assistance system is integrated in the transmission actuator (by the selector lever of the transmission actuation a double use in the form of additional control of the desired angle β met), but that here additionally Also, the calculation of the angle specification for controlling the power steering by the already existing ECU control unit of the transmission operation can take place.

Thus, in the embodiment according to 3 both the operation and the electronic control of the maneuvering assistance system completely in the transmission operating device, ie in the selector lever assembly of the motor vehicle 1 integrated. This dual use of both the selector lever and the selector lever electronics thus result in significant cost advantages compared to a separately operated maneuvering assistance system with its own, additional control unit, which would also need to be cabled separately.

The 4 and 5 show the circuit diagrams of two further embodiments of a Rangiersteuereinrichtung according to the present invention. Also in the embodiment according to 4 and 5 the operation of the maneuvering control device by the driver according to the invention again by means of the transmission actuation, in this case therefore the selector lever of the here assumed automatic transmission.

In 4 can be seen first of all a circuit diagram of a automatic transmission with the known selector lever positions P, R, N, D and S in the corresponding shift gate, as well as with a jogging M ± for manual gear selection.

Furthermore, the circuit diagram according to 4 However, another tip alley at 3 on. The further tip lane 3 is arranged so that it intersects the shift gate PRNDS in the reverse drive step position R, and includes the additional selector lever positions "Al" and "Ar" for controlling the reverse drive with trailer to the left or right.

In other words, this means that the driver can use the selector lever in the selector lever position R (and only in this) by means of corresponding sideways movements to the left or right to control the direction of the reverse drive with trailer.

The driver gives this by means of lateral movement of the selector lever in the reverse drive position R corresponding commands to the shunting ECU ECU (see. 3 ), by which the Rangiersteuergerät from the driver a target value for the angle b between towing vehicle 1 and followers 2 is communicated. The shunting controller ECU then controls the electric power steering of the towing vehicle 1 (see. 3 ) automatically so that the trailer 2 - by initial counter-steering as well subsequent permanent control of the steering angle on the towing vehicle 1 - First brought into the desired curve position and then held in the desired curve radius.

The arrangement of the other tip alley 3 in the range of the reverse gear position R of the shift gate PRNDS thus has the inherent advantage that an operation of the Rangiersteuergeräts can only be done if this is also reasonable or permissible, namely with inserted reverse gear. An unintentional activation of the maneuvering control, for example when driving forwards, is therefore already mechanically excluded.

In the embodiment according to 5 is the operation of the invention Rangiersteuereinrichtung also an existing automatic transmission with selector lever basis. The actuator of the automatic transmission is in this embodiment, however, as a monostable selector lever with jogging 4 educated. This means that the selector lever according to the circuit diagram 5 always returns to the middle position X in the tip lane when it has been brought by the driver in one of the positions R, N, D or in one of the two jogging positions and released again.

The selector lever can be used in other words in the jogging alley directly to manual gear change in other words, or it can by moving the selector lever into the shift gate RND and local selection of one of the three positions R, N or D in one of the switching states R, N or D. change.

In the embodiment according to 5 lets go the jogging alley 4 So initially use unchanged for manual gear selection, provided that the transmission, for example, by selecting the appropriate switching position along the shift gate RND - in the switch position "D" for forward drive. If the selector lever is pressed in this case from its monostable middle position in the position X to the front or to the rear, as expected, this leads to a corresponding gear change by one gear in the transmission.

In addition, however, the selector lever can also be used to control the maneuvering assistance system in the circuit diagram of the illustrated embodiment of the shunting control device according to the invention. To do this, the selector lever must only be brought once from position X to position R for reverse drive and released again.

The here monostable trained selector then falls back to the center position X in the tip alley. However, in the tip lane 4 - Due to the previous selection of the reverse gear position R - now no longer the jogging for the manual gear change active, but the control of the maneuvering assistance system. This means that the driver now by moving the selector lever forward (towards the in 5 with "Al" for "trailer left" designated position) or to the rear (in the direction of in 5 with "Ar" for "trailer right" designated position) directly with the selector lever can influence the maneuvering or control.

A decisive advantage of this embodiment of the invention is that no mechanical changes to the actuator of the vehicle transmission are required. The assistance system for reversing can thus be realized by almost exclusively software-related changes in relation to the selector lever electronics.

Alternatively, in the circuit diagram according to 5 However, an additional jogging are also provided, which is reserved exclusively for the control of the Rangierassistenzsystems, for example similar to the embodiment according to 5 ,

The 6 to 13 show further possible embodiments of the present invention integrated in a transmission control Rangiersteuereinrichtung.

In 6 can be seen first as a rotary ring with stable switching positions P, R, N, D designed transmission actuation. Inside the turning ring 5 is however an additional, monostable rocker switch 6 arranged to control the Rangierassistenzsystems. The rocker switch 6 is electrically and / or mechanically released only when the rotary ring 5 the reverse gear R is selected. In this case, again directly to the transmission operation, here by means of the rocker switch 6 , the control of the maneuvering assistance system by the driver.

In the actuator according to 7 the vehicle transmission is turned by the rotary knob 7 controlled while an additional, the rotary knob 7 enclosing turn ring 8th is used to control the maneuvering assistance system. The rotary ring 8th to control the Rangierassistenzsystems is released by the actuator again only when the rotary knob 7 as shown in the reverse driving position R is located.

In 8th an actuator with push buttons for selecting the various operating states P, R, N, D of an automatic transmission is shown. To operate the Rangierassistenzsystems is in this embodiment of the invention, the key R for selecting the reverse gear simultaneously as a rocker switch 9 executed or by an additional rocker switch 9 enclosed. The additional rocker switch 9 is - to operate the Rangierassistenzsystems - again only enabled (electrically and / or mechanically) when the R button is pressed, so when the reverse gear is selected.

In the 9 and 10 embodiments are shown for Rangiersteuereinrichtungen invention, in which the selector lever, for example, an automatic circuit or other gear change transmission is additionally designed as an actuator for the maneuvering assistance system.

In the embodiment according to 9 the operation of the maneuvering assistance system is carried out by rotation of a monostable rotary ring 10 that the shift knob 11 of the selector lever 12 encloses. Again, there is also an activation of the turning ring 10 and thus the function of the maneuvering assistance system only when engaged in the transmission, the reverse gear, or when the reverse gear on the selector lever 12 is selected.

In the embodiment according to 10 the operation of the maneuvering assistance system also takes place directly on the selector lever 12 , The selector lever 12 in this embodiment comprises a knob shell for this purpose 13 , the side over the selector lever knob 11 panned back and forth 14 can be. By appropriate pivoting 14 the knob shell 13 can thus - assuming the reverse gear is engaged - again control the Rückwärtsrangierierbetrieb means of the maneuvering assistance system.

Also in the embodiment according to 11 the operation of the maneuvering assistance system is integrated in the immediate area of the transmission actuation. As an actuating element is in the embodiment according to 11 however, the turn-push actuator 14 used the multimedia interface of the motor vehicle.

In the embodiment according to 12 and 13 the selector lever of the transmission control is also used again to control the maneuvering assistance system.

At the in 12 and 13 illustrated embodiments is the selector lever 15 each as a monostable switching element for manual gear selection by tapping 16 (Direction of travel forward or back) trained. The selection of the operating state or the gear stage of the automatic transmission takes place in the embodiments according to 12 respectively. 13 using buttons 17 ( 12 ) or by means of thumbwheel 18 ( 13 ).

However, as soon as the keys 17 or by means of the thumbwheel 18 the reverse gear R is selected, the selector lever 15 decoupled from the transmission actuation, and it can be moved by 16 of the selector lever 15 Direction of travel to the front or rear immediately control the Rangierassistenzsystems done.

As a result, it is thus clear that the invention provides a maneuvering control device for a maneuvering assistance system which permits a functionally and ergonomically optimal, intuitive control of the maneuvering assistance system by means of the already existing transmission operating device. The Rangiersteuereinrichtung invention is structurally simple and robust, far enough away from the steering wheel, and requires no additional space in the cockpit of the motor vehicle. In addition, the invention allows a cost-saving integration of the electronic Rangiersteuerung in the control unit of the transmission operation.

The invention thus makes a central contribution to the cost-effective and ergonomically sensible integration of maneuvering assistance systems into the operating concept, in particular for lorries.
