Description

The present invention relates to a method for setting a driver assistance system for vehicles, wherein the driver assistance system comprises a plurality of driver assistance modules of different functionality. Each driver assistance module has a plurality of subfunctions, wherein the subfunctions of the driver assistance modules are assigned to at least two functional groups. The first function group has fewer automation functions and fewer automatic protection functions than the second function group. Furthermore, the invention relates to a driver assistance system for vehicles having a plurality of such driver assistance modules and to an operating unit for setting the parameters of a plurality of driver assistance modules of the driver assistance system and / or for activating one of the function groups. Furthermore, the driver assistance system has a display device for displaying the set and / or adjustable parameters of the driver assistance system.

In vehicles, driver assistance systems or modules are increasingly being used for such systems, which support the driver of the vehicle during the driving task. The driver assistance systems for this purpose include sensors for detecting events in the surroundings of the vehicle, in the interior of the vehicle or events generated by vehicle devices. The data generated by the sensors are evaluated and converted into signals that assist the driver in driving the vehicle. The generated signals may lead to an output of information or warnings. Furthermore, the signals can also intervene directly in the driving event, for example, by the brakes of the vehicle are operated in a defined manner.

There are now a variety of driver assistance modules that are used in vehicles. These include, for example, traffic sign recognition, lane departure warning assistance, adaptive cruise control (ACC), automatic emergency braking, antilock braking, traction control, electronic stability program, adaptive headlight controls, parking assistance, and driver condition detection.

If a large number of driver assistance modules are used in a vehicle, there is a need for the most transparent and intuitive operation of the individual modules.

As the number of driver assistance modules increases, the operation of the modules becomes more and more difficult.

The DE 10 2009 014 544 A1 describes a method and an arrangement for status display or status display of driver assistance systems. In this case, the current states of the driver assistance systems are detected, evaluated and optically output, wherein the optical output comprises a basic display symbol that corresponds to a vehicle representation, and a plurality of different display symbols with a variable design. The display symbols are each assigned to a driver assistance system. The design of the display symbol is changed depending on the current state of the corresponding driver assistance system. In particular, the participating sensors of the driver assistance systems are visually visualized and symbolic representations of the systems spatially arranged with respect to the vehicle displayed correctly.

From the DE 10 2008 061 649 A1 a driver assistance system is known, comprising sensors for detecting the vehicle environment, actuators for engaging in the vehicle dynamics and a display unit for displaying system states of the driver assistance system. In a longitudinal guidance assistance function of this driver assistance system, a detected preceding motor vehicle is shown three-dimensionally in perspective on the display unit. Furthermore, the driving over a lane boundary can be optically visualized in different ways.

Finally, from the FR 2 927 699 A1 and the FR 2 933 659 A1 Indicators are known which are used in conjunction with an adaptive cruise control. These displays visualize a detected vehicle ahead and the distance to that vehicle.

It is also known, for a vehicle-specific function of a device of the vehicle, such as, for example, an adaptive cruise control, to display a status display which indicates the current status of this function. In addition, the user can be assisted in entering parameters for this vehicle-specific function through an interaction display. The user can z. B. enter how the time interval is to be controlled to the vehicle in front. With this input, it can be supported by a display element for an interaction ad.

In known driver assistance systems, the individual driver assistance modules can usually be switched on and off or configured separately via operating elements or a menu-driven operating system. When a single driver assistance module has been turned on, it usually becomes in the instrument cluster of the vehicle indicated by a status icon. Furthermore, in driver assistance modules that provide information to the driver, status displays of the driver assistance system are reproduced in the instrument cluster of the vehicle.

In driver assistance systems in which the sub-functions of various driver assistance modules are combined into functional groups, interaction displays are displayed during the setting of the driver assistance system, which should assist the driver in setting the parameters. This results in the problem that between a view for the operation of the overall state of the driver assistance system in which, for example, the function group is selected, and a view for the operation or adjustment of the parameters of individual driver assistance modules, such. B. the distance control, must be switched. In this case, very different interaction displays are displayed. In order to understand the relationships between these two different interaction displays, it is necessary for the user to build a complex mental model of the overall system, which makes it more difficult for the user to set the driver assistance system. As a result, the adjustment of the driver assistance system takes longer or the driver can not set the desired configuration of the driver assistance system.

The present invention has for its object a method for setting a driver assistance system and a driver assistance system of the type mentioned to create, which allow the driver of the vehicle a simple and intuitive operation of the driver assistance system.

According to the invention, this object is achieved by a method having the features of claim 1 and a driver assistance system having the features of claim 10. Advantageous embodiments and further developments emerge from the dependent claims.

In the method according to the invention for setting the driver assistance system, a graphical basic element is displayed for setting the parameters of a plurality of driver assistance modules of the driver assistance system and / or for activating one of the functional groups, comprising a plurality of sub-elements, wherein the graphical base element with respect to the sub-elements and / or the representation of the sub-elements depending on which function group is activated. Supported by the display of the graphic basic element, the parameters of the driver assistance modules are set in the method according to the invention or one of the functional groups is activated.

A driver assistance system or a driver assistance module is understood as meaning a device of a vehicle which assists the driver when driving the vehicle. Driver assistance systems or driver assistance modules according to the invention thus comprise both pure information systems which support the driver and devices which automatically influence the movement of the vehicle, wherein they can regulate the function of such devices or intervene in the function.

Since in the driver assistance system, which is used by the inventive method, the sub-functions of several driver assistance modules are summarized in different functional groups, the user can very easily and intuitively select between the individual function groups to the desired degree of automation functions and the desired level of protection functions to simple and intuitive way to set. In particular, the driver need not be familiar in detail with the functionalities of the individual driver assistance modules. He can activate them via the function groups. At the same time, however, it is possible for the driver to set the parameters of several driver assistance modules individually. In the method according to the invention, the user can very easily and intuitively establish a connection between the activation of a function group on the one hand and the setting of individual parameters of a driver assistance module, since it is supported by a common graphical element in the respective operating processes. This basic element may differ as required with regard to the sub-elements included and any additional elements. Nevertheless, the user can easily orient himself in the interaction display for setting the parameters of the driver assistance modules and for activating one of the functional groups of the driver assistance system and establish a connection between these interaction displays.

In the driver assistance system, which can be used by means of the method according to the invention, a distinction is made between status and status displays on the one hand and interaction displays on the other hand. A status display shows the current state or status of the driver assistance system during operation of the vehicle. For example, the status display indicates which function group is currently active. Since the status display may be permanently displayed during the operation of the vehicle, a graphic element is selected for the status display, which visualizes the status quickly recognizable, but requires little display space. An interaction display, on the other hand, should inform the user when setting the Driver assistance system support. The interaction display is therefore displayed when, for example, parameters for a vehicle-specific function are to be entered. In the present case, this vehicle-specific function relates to the setting of a parameter of the driver assistance system or the activation of a function group of the driver assistance system. Since interaction screens are displayed only during the operation to assist the user, they can occupy a larger area of the display area. The display elements of the method according to the invention, ie the basic graphic element, the partial elements encompassed by this and any additional elements, thus relate in particular to interaction displays and no status displays.

According to one embodiment of the method according to the invention, the graphic basic element comprises a representation of a vehicle, in particular a perspective view of a vehicle. Furthermore, the representation of the vehicle is preferably surrounded by ring segments. The ring segments visualize activated and / or selectable automatic protection functions of the driver assistance system.

A ring is understood to mean the area between two closed concentric lines, in whose common center the representation of the vehicle is arranged. A ring segment is a part or section of this ring. In particular, the ring is an annulus formed by the area between two concentric circles. Preferably, the ring segments are arranged on a plurality of concentric rings or partial rings, wherein the number of rings or partial rings corresponds to the number of functional groups and possibly any subgroups which are assigned to the sub-functions of the driver assistance modules. For example, three ring segments can be arranged on each ring or partial ring which is assigned to a functional group. Two ring segments are arranged laterally from the representation of the vehicle and a ring segment is arranged in the direction of travel before the representation of the vehicle. The ring segments also visualize in this way the effective direction of the protective function, namely in each case a lateral effective direction and a direction of action forward.

According to a development of the method according to the invention, the ring segments form a plurality of concentric around the perspective view of the vehicle arranged sub-rings, the ring segments of the radially innermost ring serving the representation of the first functional group and serve the ring segments of the radially outermost ring representation of the second functional group. In this way one achieves a very simple and intuitively understandable visualization of the protection functions of the driver assistance system. By displaying ring segments around a vehicle symbol, the driver is visualized as a metaphor a protective shield for the vehicle. Due to the concentric arrangement of the ring segments, the degree of protection or the level of protection is visualized.

According to one embodiment of the method according to the invention, all ring segments to the function groups can always be represented in the graphic primitive, the ring segments, which belong to protective functions that are activated, being highlighted, for example by a representation in a specific color or by a brighter representation as the ring segments belonging to non-activated protection functions.

According to a development of the method according to the invention, the viewing angle of the perspective view of the vehicle in the basic graphic element is selected as a function of which functional group is activated. Alternatively or additionally, the ring segments can be shown in perspective, wherein the viewing angle of the perspective view of the ring segments in the graphical primitive selected depending on which functional group is activated. When the first function group is activated, a relatively large viewing angle is selected to an imaginary road on which the illustrated vehicle is located. With the activation of higher-order function groups, the viewing angle is increasingly flattened. When activating the function group with the largest automatic protection function and most automation functions, i. H. For example, the second function group, the shallowest viewing angle is selected. In this case, in addition to the perspective view of the vehicle and possibly the ring segments as a graphical additional element another vehicle can be displayed. The representation of this further vehicle visualizes a preceding vehicle detected by the driver assistance system. The distance between the perspective representation of the vehicle in the graphic basic element and the representation of the further vehicle can be selected, for example, as a function of the time interval of the vehicle from the further vehicle which has been detected by a driver assistance module in the surroundings of the vehicle. In this case, the time interval is understood to be the time that the own vehicle needs at the current speed in order to reach the instantaneous position of the vehicle in front.

Furthermore, additional information on set and / or adjustable parameters of the driver assistance modules can be displayed in addition to the graphic basic element as additional graphic additional elements if the second functional group is activated. These additional graphic elements supplement the interaction display of the graphical primitive to assist the user in setting the appropriate parameters.

Without the driver assistance system, the driver directly influences the movement of the vehicle. At most signals or movements of driver-operated controls, such as the pedals, the gear lever or the steering wheel, are transmitted to corresponding devices of the vehicle, which influence the movement of the vehicle. Such locomotion of the vehicle corresponds to the lowest level of automation. In the case of a higher degree of automation, part of the intervention in devices which serve to move the vehicle is in part automatically intervened. For example, the steering of the vehicle or the acceleration in the positive or negative direction is intervened. At a still higher degree of automation is intervened so far in facilities of the vehicle, the certain the types of vehicle movement, z. B. a straight ahead, can be performed automatically. At the highest level of automation, navigation system routes can be driven essentially automatically. It should be noted, however, that while the driver may increasingly relinquish control of vehicle guidance by choosing a higher level of automation. However, he can regain this control immediately by actively steering or pressing the pedals.

Furthermore, the various driver assistance modules fulfill various safety functions that determine the degree of automatic protection functions. First of all, the driver only receives information about a driver assistance module or several driver assistance modules that influences the driver in the way in which he drives the vehicle. In a higher level of safety functions, warnings are issued that require a driver's immediate reaction. However, with this level of safety functions, the driver assistance modules do not actively and automatically intervene in the function of the devices which influence the movement of the vehicle. In an even higher degree of safety functions is partially intervened automatically in facilities that serve the movement of the vehicle. For example, intervention in the steering of the vehicle or acceleration in the positive or negative direction is particularly preventive. With an even higher degree of safety functions, intervention is made in facilities of the vehicle which influence the movement of the vehicle so that maneuvers of the vehicle can be carried out automatically, such as emergency braking or a deliberate avoidance maneuver to avoid a collision.

The instructions issued by the driver assistance modules alert the driver of the vehicle to certain dangers. This increases the safety when driving the vehicle. With an active engagement of a driver assistance module in the locomotion of the vehicle even dangerous driving situations, such as collisions or uncontrolled movements of the vehicle can be avoided, even if the driver does not intervene directly in the driving. In the case of the safety functions of the driver assistance system, however, the driver always retains full control and responsibility for the driving situation. The driver assistance system intervenes only in the event of a collision hazard.

In an embodiment of the method according to the invention, in the first functional group, the driver assistance modules only automatically intervene in the movement of the vehicle when the driver assistance modules have detected that there is a high probability of an imminent collision. The first functional group is preferably subdivided into at least two subgroups. In the first subgroup, as explained above, the driver assistance modules automatically intervene in the movement of the vehicle only when the driver assistance modules have detected that there is a high probability of an imminent collision. In the second subgroup, the driver assistance modules additionally issue warnings when the driver assistance modules have detected that there is an average probability of an imminent collision.

According to one embodiment of the method according to the invention, in the second function group, the driver assistance modules automatically intervene in the movement of the vehicle in order to assist the driver even if no high probability of an imminent collision has been detected by the driver assistance modules. The second function group thus serves the continuous control to avoid risks and to increase the comfort of the driver. In this functional group, the vehicle automatically assumes in particular essential tasks for the continuous control of the vehicle, such. B. the lateral and longitudinal control. The driver must monitor the driver assistance system and only in case of imminent failure of the driver assistance system intervene when the second function group of the driver assistance system is activated.

According to a development of the method according to the invention, the individual functional groups can each be activated separately for functionalities which act in the longitudinal direction of the vehicle and for functionalities which act in the transverse direction of the vehicle. Functions that act in the longitudinal direction of the vehicle include, for example, the adaptive cruise control. Functions acting in the transverse direction of the vehicle include, for example, a lane departure warning system.

The driver assistance system according to the invention for vehicles comprises a plurality of driver assistance modules of different functionality, each driver assistance module having a plurality of subfunctions. The sub-functions of the driver assistance modules are assigned to at least two functional groups. The first function group has fewer automation functions and fewer automatic protection functions than the second function group. Furthermore, the driver assistance system comprises an operating unit for setting the parameters of a plurality of driver assistance modules of the driver assistance system and / or for activating one of the aforementioned function groups. Furthermore, the driver assistance system comprises a display device for displaying the set and / or adjustable parameters of the driver assistance system. Finally, the driver assistance system comprises a control device which is coupled to the operating unit and the display device and by means of which a graphic basic element can be displayed for setting the parameters of a plurality of driver assistance modules of the driver assistance system and / or for activating one of the functional groups. The graphical primitive comprises a plurality of sub-elements, wherein the graphical primitive differs in terms of the sub-elements and / or the representation of the sub-elements depending on which functional group is activated.

The driver assistance system according to the invention is in particular designed to carry out the method according to the invention described above. It therefore also has the same advantages as the method according to the invention.

The operating unit is in particular a mechanical operating element which is arranged on the steering wheel of the vehicle. Furthermore, the operating unit may alternatively or additionally comprise a touch-sensitive surface, which is in particular formed on a display surface of the display device, so that a so-called touch screen is provided. By means of the operating unit, the user can initiate an operating procedure, wherein the graphic basic element is displayed in an interaction display. The type of representation of the sub-elements of the graphical primitive and the representation of any additional elements is chosen by the control device in dependence on which functional group is activated.

In the following the invention will be explained by means of embodiments with reference to the drawings.

In reference to 1 the basic structure of an embodiment of the driver assistance system according to the invention is explained:
The driver assistance system comprises several driver assistance modules 10-1 . 10-2 . 10-3 . 10-4 , ..., 10-n hereinafter referred to generally by the reference numeral 10 be designated. To these driver assistance modules 10 In particular, a traffic sign recognition, a lane detection system, a proximity control, a lane departure warning and a module that can perform certain driving maneuvers automatically include. The driver assistance modules 10 are known per se. They include a variety of sensors to detect driving situations and the Generating data describing the driving situation in the environment of the vehicle. The driver assistance modules 10 are with a control device 2 coupled to which they transfer the collected data for further processing.

The driver assistance system further comprises a display device 5 with a display area 6 , The display area 6 can be provided by a display, in particular a liquid crystal display or a plasma display, of any type. Furthermore, the display device 5 a head-up display or a head-down display in which the display is projected onto a surface, for example on the windshield. The display device 5 is with the control device 2 coupled. The control device 2 can generate graphics data on the display area 6 can be displayed.

The control device 2 is also with a control unit 3 connected, via which the user parameters of the driver assistance modules 10 of the driver assistance system and / or can activate one of the function groups, as will be explained later. The operating unit 3 can z. B. have a mechanical control element, such as a cross rocker 4 , which is arranged on the steering wheel of the vehicle. Furthermore, the mechanical control element can be a rotary push-button. The mechanical control is z. B. equipped with a touch sensor that detects when the user touches the control element.

Instead of the mechanical operating element or in addition to the mechanical operating element can also on the display surface 6 a touch-sensitive surface can be provided, via which the user can make inputs. In this case, a so-called touch screen is provided.

Furthermore, in the environment of the control unit 3 an approach detection device (not shown) provided with the control device 2 coupled and detected when an actuator, such as the hand of a user, the control unit 3 approaches.

The control device 2 is further with a data bus 7 coupled to the vehicle. About this data bus 7 can the control device 2 Transferring control data to devices of the vehicle which control the movement of the vehicle. These devices include in particular the power supply for the engine of the vehicle, the vehicle brakes and the steering of the vehicle.

Finally, the control device 2 with a speaker 4 and optionally haptic signaling agents 9 be connected via the information and warnings can be output acoustically and / or haptically.

In the control device 2 are those of the driver assistance modules 10 transmitted data processed on the one hand, the control data are generated, which control the movement of the vehicle. On the other hand, if necessary, acoustic or haptic data for output via the speaker 4 or haptic signaling agents 9 generated and graphical data for display on the display area 6 , The different functionalities of the driver assistance modules are thereby 10 assigned to different functional groups, as explained below:
The first function group is divided into two subgroups. The first subgroup are subfunctions of the driver assistance modules 10 which only automatically intervene in the movement of the vehicle if a high probability of an imminent collision has been detected. This first subgroup of the first functional group thus represents an automatic driving intervention for collision avoidance in an emergency. In this case, the driver of the vehicle drives himself and has full control of the vehicle. The driver assistance system automatically intervenes in the movement of the vehicle only in an emergency, ie in the event of a high probability of collision and if the driver does not react, in order to avoid an accident. For example, emergency braking is performed. Further, a steering movement for dodging an object may be performed or the vehicle may be accelerated to avoid a collision with an oncoming vehicle.

The second subgroup of the first function group comprises the subfunctions of the driver assistance modules 10 which additionally issue warnings if an average probability of an imminent collision has been detected. For example, the warnings can be heard acoustically via the loudspeaker 4 , graphically across the display area 6 and / or haptic via the signaling means 9 , z. B. by a vibration of the steering wheel, are issued. Also in this second subgroup of the first function group, the driver drives himself and has full control of the vehicle. However, if an average probability of collision has been detected and a driver's response is absent, the driver assistance system warns the driver to cause the driver to preventively react.

The second function group becomes sub-functions of the driver assistance modules 10 summarized, which automatically intervene in the movement of the vehicle. If this function group is active, the driver is supported even if no high or medium probability of imminent collision has been detected. In this case, a continuous control of the movement of the vehicle to avoid risks and to increase comfort for the driver. If this function group is active, the driver assistance system takes over essential tasks for the continuous control of the movement of the vehicle, eg. B. the lateral and longitudinal control. However, in this case too, the driver must monitor the vehicle so that it can continue to intervene manually in the event of an imminent failure of the driver assistance system and override the control signals of the driver assistance system.

When in the driver assistance system, the operating unit 3 is pressed to activate a certain function group or parameters of a driver assistance module 10 to set, generates the control device 2 an ad on the display area 6 of the vehicle, which supports the user in this operation. Thus, an interaction display is generated. This interaction display includes a graphic primitive 1 Both when setting the overall state of the driver assistance system, ie in particular when selecting a function group, as well as when setting individual parameters of a driver assistance module. The representation of the graphic element 1 will be referred to below with reference to 2 explains:
The basic graphic element 1 includes several sub-elements. In the middle of the graphic primitive is called subelement 8th the symbol of a vehicle is shown. In particular, a perspective view of one's own vehicle is displayed, the viewing angle being selected from the top rear. The viewing angle in this case is defined by the angle that an imaginary road on which the illustrated vehicle is located with the viewer's line of connection to the vehicle. To the subelement 8th around which represents the vehicle are several circular ring segments 11-1 to 11-3 . 12-1 to 12-3 . 13-1 to 13-3 arranged. These circular ring segments are on three concentric circular rings or partial circular rings 11 . 12 and 13 arranged, in the center of which the subelement 8th located for the vehicle. On every annulus 11 . 12 and 13 are three circular segments 11-1 to 11-3 respectively. 12-1 to 12-3 respectively. 13-1 to 13-3 arranged. The circular ring 11 the above-explained first subgroup is assigned to the first functional group, the circular ring 12 the second subgroup is assigned to the first function group and the annulus 13 the second function group is assigned. By means of the circular ring segments 11-1 to 11-3 . 12-1 to 12-3 . 13-1 to 13-3 the user is shown which function group is activated in which effective direction and which functional groups are in principle activatable in which effective directions. The circular ring segments 11-2 . 12-2 . 13-2 represent to the respective function group a direction of action in the longitudinal direction of the vehicle forward. The circular ring segments 11-1 . 12-1 . 13-1 represent for the respective function group a direction of action to the left side of the vehicle from the perspective of the driver while driving. The circular ring segments 11-3 . 12-3 . 13-3 represent the direction of action to the right for the respective function group from the perspective of the driver of the vehicle.

By means of the control unit 3 For example, the driver can activate and deactivate functional groups or subgroups separately for the three effective directions if the graphic basic element 1 is shown. The activation or deactivation is visualized to the user in that the associated circular ring segment 11-1 to 11-3 . 12-1 to 12-3 . 13-1 to 13-3 is grayed out in the deactivated state and highlighted in the activated state, z. B. bright or colored, is displayed.

In the following, an embodiment of the method according to the invention with reference to the 3 to 6 explains:
As in the 3 to 6 shown is the display area 6 a freely programmable display area of the instrument cluster of the vehicle. On the display surface 6 will also be round instruments 17 and 18 displayed for the speed and speed display of the vehicle. Alternatively, these round instruments can also be used, in part, as physical display instruments of the display area 6 be superimposed arranged. Inside the round instrument 17 is a display area 19 formed in which display elements 14 for a status display of the driver assistance system of the vehicle. Between the two round instruments 17 and 18 is another display area 15 formed in which display elements are displayed for an interaction display, ie the basic graphic element 1 as well as any additional elements, as will be explained later.

It is initially assumed that the first function group of the driver assistance system is activated. This is indicated by the status indicator of the display element 14 in the display area 19 visualized in the instrument cluster of the vehicle.

Is now detected by means of the proximity detection device that the fingertip of the user of the control unit 3 approaches, a display change is made by the control device 2 generated, at first the display element 14 for status display or a copy of it towards the display area 15 moved for the interaction ad. In the area of the display or the elements of the round instrument 17 disappears the display element 14 and finally dives in display area 15 back up. However, in the display area 15 no longer the display element 14 for the progress bar, but the corresponding display element for the interaction screen. If - as assumed here - the first function group of the driver assistance system is activated, thus becomes the basic element 1 displayed. Furthermore, a road is indicated on which the vehicle is located. This basic element 1 goes to the middle of the display area 15 move until the animation according to the display 3 ends. The display element 14 will be back in the display area after the animation has finished 19 shown in the instrument cluster of the vehicle. The user can now use the control unit 3 - as explained above - change the activation of the functional groups.

If the second subgroup of the first functional group is also active, the time of a warning of an emergency intervention could possibly also be manipulated by the user. This manipulation is possible in particular only if the second function group is deactivated. The user can place a specific button on the touch-sensitive surface of the display area 6 Press to enter a setting of the operating unit 3 to activate or directly a corresponding adjustment button of the control unit 3 actuate. By means of further operating elements of the operating unit 3 the user can then set the time of the warning accordingly. In this case, this time is from a corresponding additional element in the interaction display in addition to the primitive 1 displayed.

If the user returns his hand from the control unit after completion of the operation 3 this is detected by the proximity detector. After a defined time interval, an opposite animation will be triggered. The basic element 1 for the interaction display thus moves in the direction of the display area 19 , disappears behind the display for the round instrument 17 or behind the physical element of the round instrument 17 and finally appears in the display area 19 again as an indicator 14 for the status display. If the status of the driver assistance system has changed, a correspondingly changed display element will also appear 14 for the status display.

If the user is now starting from the in 3 shown display by means of the control unit 3 the second function group is activated, the display changes as follows:
The perspective view of the partial element 8th for the vehicle of the basic element 1 and possibly the perspective view of the circular ring segments 11-1 to 11-3 . 12-1 to 12-3 . 13-1 to 13-3 is changed in terms of the viewing angle for the perspective. The viewing angle becomes flatter. At the same time, the representation of the primitive 1 reduced.

By changing the viewing angle of the perspective view of the sub-element 8th for the vehicle and possibly for the circular ring segments 11-1 to 11-3 . 12-1 to 12-3 . 13-1 to 13-3 a larger portion of the road on which the vehicle shown is visible. If the driver assistance system has detected a vehicle in front, this is in perspective before the sub-element 8th for your own vehicle based on an additional element 16 represented for a preceding vehicle. The removal of the additional element 16 for the preceding vehicle of the sub-element 8th for the own vehicle thereby represents the time interval between the two vehicles measured by the driver assistance system.

Furthermore, a green symbol 20 for showing that the cruise control is activated. Furthermore, an additional element 21 displayed, which reproduces the recommended speed of the longitudinal control.

If the second function group is active, the user can also use the control unit 3 certain settings regarding the parameters of individual driver assistance modules 10 make. For example, parameters for the automatic control of the vehicle can be set. This can be done either by available operating elements of the operating unit 3 or by switching to a setting mode, so that a previously used for the activation of the function groups control element can now be used for the settings. In the setting mode, the manipulatable parameters are displayed graphically in the interaction display as additional graphic additional elements and optionally highlighted graphically with respect to other elements which can not be changed in the setting mode.

In 5 a corresponding display is displayed, which is displayed when setting the parameter for the time interval of the adaptive cruise control. As an additional element 22 be more concentric ring sections between the circular segment 13-2 and the additional element 16 for the vehicle ahead. One of the segments of the additional element 22 is highlighted. This represents the currently selected time interval. By means of the control unit 3 This distance can be changed, which corresponds to the additional element 22 is visualized.

In 6 is an alternative display reproduced in which as an additional element 23 Bar segments are displayed.

In reference to 7 another example of an interaction ad is explained:
In this case, the ring segments are bars 24 . 25 and 26 concentrically around the subelement 8th extend for the representation of the vehicle. The time interval is not in this case, however, by the additional elements 22 respectively. 23 visualized but by the arrangement of the bars 26 the outermost ring of the primitive 1 , That before the subelement 8th segment of the beam for the representation of the vehicle 26 of the outermost ring can, as by the dashed bars 27 indicated by the subelement 8th for the own vehicle away, towards the representation of the additional element 16 be shifted for a preceding vehicle according to the choice of the time interval. A corresponding change in the segments of the bar 26 for the outermost ring can be selected for the setting of the transverse control. If a different time interval is also selected in this direction, the bar changes 26 according to the dashed representation 27 in 7 ,
