Method and apparatus for displaying availability

a first driving mode of a vehicle

The invention relates to a method for indicating availability of a first driving mode of a vehicle, wherein the vehicle is operable at least in the first driving mode, in which the vehicle is at least partially automatically guided, and in a second driving mode, in which the vehicle is not automatically guided is.

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. In certain situations, the driver assistance systems can completely take over the driving of the vehicle. The vehicle is then guided fully automatically without the driver having any influence on the driving of the vehicle.

To the driver's confidence in automatically guiding the vehicle or the

To increase the functionality of driver assistance systems, systems are known for indicating interventions of the driver assistance systems in the driving sequence.

DE 10 201 1 121 948 A1 describes a preview of actions of an autonomous driving system. A vehicle driver is informed about a driving maneuver planned by means of a driver assistance system and carried out by the motor vehicle. An up-to-date traffic situation is recorded on the basis of environmental data, a driving maneuver is planned on the basis of the acquired environmental data, and the driving maneuver as well as at least a part of the acquired environmental data is displayed in an image on a display.

DE 10 2010 014 499 B4 describes a method for operating a lane departure warning system for multi-lane turning in a motor vehicle. In this case, road markings are displayed in a head-up display contact-analogue. In particular, the lane that the driver should hold is highlighted.

A disadvantage of the prior art, however, is that the user is not taught when a use of a fully or semi-automatic driving mode is even possible. It is therefore an object of the present invention to provide a method and a device of the type mentioned in a vehicle, with which a driver can quickly and intuitively detect when a semi-automatic or fully automatic driving a vehicle is possible.

According to the invention this object is achieved by a method having the features of claim 1 and a device having the features of claim 9. advantageous

Embodiments and developments are subject matters of the dependent claims.

In the method according to the invention, it is detected whether the vehicle is in the first or the second driving mode. First environmental data from the environment of the vehicle are determined. When it has been detected that the vehicle is in the second

Driving mode is based on the first environment data is a beginning of a

Route section predicts from which the first driving mode is available. Depending on the predicted beginning of the route section, a first display element is generated on a first display area, by which the predicted start of the

Section is shown in a first representation.

The driver is taught by the inventive method in a simple and fast way, from when the first driving mode can be used. For example, the first display surface is arranged in the windshield of the vehicle and in particular represents a display surface of a head-up display. As a result, the driver does not have to look away from the road to see the first display element.

The first environment data can in particular be installed in the vehicle

Vehicle components are determined. The vehicle components can do this

in particular a navigation system, a light and / or weather sensor or a data unit. The first environment data are then dependent in particular on the route traveled by the vehicle, on light and / or weather conditions in the surroundings of the vehicle or on data stored in the data unit. In particular, historical data can be stored in the data unit. For example, it can be determined on which road sections the first driving mode was available in the past.

In particular, depending on the determined first environmental data, an end of the route section is predicted, from which the first driving mode is no longer available. The first representation of the first display element may then comprise a representation of a roadway, wherein the predicted start of the route section represented by a marker and the road section of the road, which is between the predicted start of the route section and the predicted end of the road

Section is marked, is displayed. For example, sections of the route that are very well marked and signposted are particularly well suited for fully automatic driving. In addition, an area in which the first driving mode is available can thereby be displayed visually lifted off the area in which the first driving mode is not available. This advantageously leads the driver directly to see on which sections the first driving mode is available and which is not.

In particular, the first display element represents a contact-analog display element. This means that the first display element is displayed as if it were a direct component of the roadway. As a result, the display element in the field of vision of the driver on a

Display surface of the head-up display not disturbing.

In one embodiment of the method according to the invention, the predicted start and / or the predicted end of the route section depend on a predicted time and / or a predicted length of a route up to the start and / or end of the route section. The predicted beginning and / or the predicted end of the route section therefore comprise a temporal and / or a local component. If the vehicle is stuck in a traffic jam, the predicted length of the route is not increased, but the predicted time is. By considering both components, the predictive power of the prognosis can be advantageously increased.

Furthermore, in the second driving mode on a second display area a second

Display element is displayed by which the predicted start of the route section is displayed in a second representation. The second display surface is arranged, for example, in a combination instrument of the vehicle. The display area of the

Combination instrument is located behind the steering wheel of the vehicle and in the second driving mode, so when the driver drives the vehicle itself, within the field of view of the driver. The driver merely has to lower his or her gaze a little in order to be able to detect the display content of the second display area. The driver is thus presented in different ways the availability of the first driving mode.

In this case, the second display element in particular comprises a bar display, wherein a length of the bar indicates a remaining distance and / or a remaining time until the predicted beginning of the route section is reached. The representation of the second display element is in particular iconographic. In addition, the length of the bar is adjusted to the remaining distance and / or time.

For example, a circle circumference or a ring, in particular a circular ring, is filled up like a beam. Upon reaching the predicted start of the section is the

Circle circumference or circumference then closed.

In a further embodiment of the method according to the invention, when the first driving mode is available, it is changed to the first driving mode. It will be second

Environment data determined. Depending on the second environment data, rule objects are added to the first display element. The second environment data are thereby provided in particular by sensors which are also used for conventional driver assistance systems.

The second environment data is different in nature than the first environment data. The first environment data includes data on road conditions, light and / or

Weather conditions on the traveled route and are not recorded in the immediate vicinity of the vehicle. For example, they may already be ready when the vehicle starts to travel and also include environmental data from the surroundings of the vehicle which the vehicle will pass along the route during the entire journey, and thus also in the future. The second environment data, however, are determined from the immediate vicinity of the vehicle, ie where the vehicle is currently in the moment of data collection. The second environment data has an immediate impact on how the vehicle is run. They include other road users, traffic signs and / or traffic lights. Although the place at which traffic signs and traffic lights are already known to start driving. However, what they indicate when the vehicle passes this place, can be determined only immediately at this location or shortly before.

In the first driving mode, the vehicle is partially or fully automatically by

Driver assistance systems led. In the context of the invention, rule objects are therefore objects to be understood in which the control is oriented by a driver assistance system. In this case, for example, in the longitudinal control of the distance to the preceding

Vehicle regulated. The preceding vehicle is therefore used as a control object.

This is then displayed in a graphical representation as a rule object on the display area. Lanes, traffic signs, traffic lights or information provided by a navigation system can also be used as rule objects. The weather conditions can also be a rule object. By adding the rule objects to the first display element, the driver is signaled that the system has detected all relevant information for driving the vehicle and all dangers on the road. This is to teach the driver to trust the system in the fully or partially automatic guidance of the vehicle.

In a further embodiment, the second environment data becomes such

Rule objects of the added rule objects, which have an influence on the

Driving behavior of the vehicle in the first driving mode have. The determined rule objects are then displayed marked. This indicates to the driver that the system has also recognized the information and hazards that a driving maneuver on the part of the driver

Make vehicle necessary. This also contributes to the driver's confidence in the system. In particular, the driver directions are displayed, which

For example, a detected vehicle or a detected pedestrian is likely

take. In addition, the user can then also evasive maneuvers in the head-up display are displayed.

In particular, in the first driving mode on a third display area, a third

Display element is displayed by which a predicted end of the route section is displayed, from which the first driving mode is no longer available. The third

Display element corresponds for example to the second display element. In addition, a time can still be displayed for which the first driving mode is still available.

The third display surface is arranged in particular in the center console of the vehicle. If the vehicle is in a fully automatic mode in the first driving mode, the driver will direct his attention to a display area in the center console of the vehicle. By means of this display area, the driver can then dedicate employment activities, such as watching movies, writing e-mails or other activities. Since in the fully automatic driving mode, the driver's attention is thus mainly directed to the third display area, there is advantageously displayed a display element which clearly indicates to the driver when the first driving mode is no longer available and he has to assume driving responsibility again. Should the driver want to be sure during a fully automated journey that the vehicle recognizes all dangers and initiates all necessary driving maneuvers himself, he can always direct his gaze to the first display area.

In another embodiment, an uncertainty level of the driver is determined. If the degree of uncertainty falls below a predetermined limit, the first display element and the control objects are masked out on the first display area in the first drive mode. If a driving maneuver is imminent, for example an evasive maneuver or an overtaking maneuver, the first display element and / or the rule objects can be displayed again. A maneuver-dependent fade also increases the driver's confidence in the system.

Furthermore, it is determined how long the first driving mode is still available. If the time still available falls below a predetermined value, the first and / or the third one becomes

Display element highlighted in the first driving mode. This informs the driver that he has to assume responsibility for driving again.

The invention further relates to a device for displaying an availability of a first driving mode of a vehicle, wherein the vehicle, at least in the first driving mode in which the vehicle is at least partially automatically guided, and a second driving mode in which the vehicle is not automatically guided operable is. The device comprises a detection unit, by means of which it can be detected whether the vehicle is operated in the first or the second driving mode. In addition, the device comprises a determination unit, by means of which first environmental data from the surroundings of the vehicle can be determined, and a forecasting unit, by means of which a start of a route section can be predicted, from which the first driving mode is available, if from

Detecting unit has been detected that the vehicle is in the second driving mode. Furthermore, the device comprises a first display area and a

Control device, by means of which the first display surface in dependence on the

Predicted start of the route section is controlled such that on the first display area, a first display element is generated by which the predicted start of the route section can be displayed in a first representation.

The device according to the invention is in particular designed such that the

inventive method can be performed. It therefore also has all the advantages of the method according to the invention.

The first display surface is arranged in particular in the windshield of the vehicle. A second display surface is arranged in a combination instrument of the vehicle and / or a third display surface is arranged in the center console of the vehicle.

The invention will now be explained by means of embodiments with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the device according to the invention, FIG. 2 shows an exemplary embodiment of an arrangement of the device from FIG. 1 in a vehicle,

FIG. 3 shows a flowchart of an embodiment of the method according to the invention,

FIGS. 4a and 4b show examples of display elements produced on the display surfaces in the second drive mode and

FIGS. 5a and 5b show examples of display elements produced on the display surfaces in the first drive mode.

FIGS. 1 and 2 show an exemplary embodiment of a device 2 according to the invention and its arrangement in a vehicle 1.

The device 2 according to the invention initially comprises three display surfaces 3, 4 and 5.

The first display surface 3 is arranged in the windshield 19 of the vehicle 1. In particular, it is part of a so-called head-up display (HUD). The display in a HUD allows in particular a contact-analogue display, are superimposed on the display elements of the real road, and thus only minimally disturbing in the field of view of the driver are displayed. In addition, the driver does not have to look away from the road to see the display surface 3 when driving the vehicle 1.

The second display surface 4 is arranged behind the steering wheel 7 of the vehicle 1 and constitutes a display surface of a freely programmable combination instrument (FPK) 8.

The third display surface 5 is arranged in the center console 6 of the vehicle 1. This represents in particular the display area 5 of an infotainment system. For example, this display area 5 is a touch screen, via which the infotainment system can be operated.

All three display surfaces 3, 4 and 5 are connected to a control device 9. The

Control device 9 in turn is connected to a detection unit 10. The

Detecting unit 10 detects in which driving mode the vehicle 1 is located. In this case, the detection unit 10 differentiates in particular between a first and a second driving mode. In the first driving mode, the vehicle 1 is guided, for example, fully automatically. The vehicle 1 takes over the longitudinal and transverse guidance on the road. The vehicle 1 gives gas and brakes automatically. In the first driving mode, the driver can therefore different

Dedicate activities as the vehicle management. For example, the driver can watch movies or write emails.

In general, an automatic driving of a vehicle 1 on well-marked routes is possible. For example, if the lane marking is missing on the road, automatic guidance is only possible with difficulty. Also prevailing light and

Weather conditions may decide whether automatic guidance of the vehicle 1 is possible. If it is dark, pedestrians, for example, are hard to detect. An evasive maneuver may not be executed in time. Even traffic signs are difficult to recognize in bad light and weather conditions, so that, for example, an automatic adjustment of the speed is difficult.

The second driving mode, on the other hand, is defined as a driving mode in which the vehicle 1 is guided by a person. This means that the responsibility of driving the vehicle lies with the driver alone. The driver operates the pedals (accelerator, brake pedal) and steers himself. The second

Driving mode is always available to the driver. An availability check of the second driving mode is therefore not necessary.

The control device 9 is also connected to a detection unit 1 1. By means of the determination unit 11, a beginning of a route section can be determined, from which the first driving mode is available. The beginning of the route section may be a specific geographical location on the route traveled by the vehicle 1. Alternatively, the beginning of the route section may also be a time from which the first driving mode is available.

In order to determine the time and / or distance point from which the first driving mode is available, the determining unit 1 1 is connected to a plurality of vehicle components 12.1 to 12.3. The vehicle component 12.1 is, for example, the navigation system of the vehicle 1. This provides route information, by means of which it can be determined whether an automatic driving of the vehicle 1 is possible or not on a certain route.

The vehicle component 12.2 represents, for example, a light and / or weather sensor. This can measure light and / or weather conditions in the surroundings of the vehicle 1. In addition, the light and weather sensor may also include a weather forecast for the future route. This information may then be used to predict a start of a leg from which the first driving mode is available.

The vehicle component 12.3 may include a data unit that collects and evaluates driving data. For example, the data unit in combination with the

Navigation system Store routes on which an automatic driving of the vehicle was possible in the past.

The data of the vehicle components are then used by a forecasting unit 16, which is integrated in the determination unit 11, to predict a start of a route section, from which a change from the first drive mode to the second drive mode is possible.

With reference to FIG. 3, an embodiment of the method according to the invention is explained:

The starting point here is first that the driver leads the vehicle 1 itself. The vehicle 1 is thus in the second driving mode.

This is detected by the detection unit 10 in step S1.

In step S2 first environmental data are determined. The first environment data are thereby determined with the aid of data of the vehicle components 12.1 to 12.3.

In step S3, the first environment data are transmitted to the forecasting unit 16. It is then predicted a time and / or a length of a route for which must be continued in the second driving mode, since the first driving mode is not yet available. From this time and / or the length of the route a start of a route section is determined, from which the first driving mode is expected to be available. In addition, an end of the route section is determined, from which the first driving mode will probably no longer be available.

If the beginning of the route section and the end of the route section were predicted, a first display element 13 is generated on the first display area 3 in step S4, as shown for example in FIG. 4a. The first display element 13 represents the beginning of the route section in a first representation. The first display element 13 includes a representation of a roadway. The predicted start of the section is shown as limit 13.1 on the road. The predicted end of the section, however, is so far ahead that it can not yet be displayed on the road. The route section 13.2 is located between the predicted start of the route section and the predicted end of the route section. The section 13.2, which lies between the predicted beginning and the predicted end, is marked marked. As a result, the section 13.2 on which the first driving mode is available stands out from the area of the route in which the first driving mode is not available. The marking can be, for example, a coloring. The first display element 13 becomes

especially superimposed on the real road surface. The first representation of the predicted start of the route section corresponds to a contact-analogue

Presentation. This means that the first display element 13 is shown superimposed on the real roadway and thus disturbs little in the driver's field of vision.

At the same time, in step S4 of the method, a second display element 14, as shown in FIG. 4b, is generated on the second display surface 4, that is to say the display surface of the FPK 8, which predicts the start of the route section to a second

Representation represents. The second display element 14 comprises a circular bar representation 14.1. The bar 14.1 represents the circumference of a circle. The arc length of the bar 14.1 represents the route length that remains until the first driving mode is available. The longer the arc length, the shorter the distance that has to be traveled until the first driving mode is available. The arc length of the beam is constantly adjusted to the current length of the remaining track. In addition, the display element 14 comprises the letters "AP", which mean autopilot. As a result, the driver can unambiguously assign the second display element 14 to the autopilot.

During the manual drive, the driver's gaze is focused mainly on the road in the direction of travel in order to be able to grasp the traffic at any time.

The first display element 13 illustrates kontaktanlog and the second display element 14 illustrates iconographically, from when the autopilot function is expected to be available. The two display elements 13 and 14 therefore represent an availability display of the autopilot. In this case, the availability representation is based on distance-based data in order to avoid too frequent adaptation during the course of the journey. Vary

Environmental conditions, the autopilot may be available later. The forecast is then adjusted. The boundary 13.1 of the display element 13 is then moved backwards and the change in the bar length of the display element 14 is paused. When the driver with the vehicle 1 reaches the area in which the first driving mode is available, the driver is notified in step S5 of the method.

The first display element 13 on the display surface 3 of the HUD then contains only the marked section 13.2.

The second display element 14 on the display surface 4 of the FPK 8 is shown changed. The bar 14.1 is then displayed as a closed circle. For example, the display elements 13 and / or 14 may be changed in color when the autopilot is available.

In addition, another visual cue can be given in the form of a written note without any acoustic indication that the autopilot is available.

If the driver changes e.g. by an operator action from the second to the first

Driving mode, this is detected by the detection unit 10 in step S6. An automatic change to the first driving mode is also conceivable. That the vehicle 1 automatically changes to the first driving mode when available should, however, have been previously set by the driver himself. As a result, the driver's driving responsibility is not withdrawn without his consent.

In step S7 of the method, second environment data are determined. The second

Environmental data then includes the presence of other road users, the distance of their own vehicle 1, traffic signs, traffic lights, etc. Rule objects 15 are then added to the first display element 13 on the first display surface 3 as a function of the determined second environmental data. were

For example, other road users determined, they are displayed as rule objects 15.1. Traffic signs and traffic lights are displayed as rule objects 15.2. As a further rule object 15.3, the distance is displayed, which is to be maintained between the vehicle ahead and the own vehicle 1. In addition, the end of the route section, from which the first driving mode is no longer available, is displayed as limit 13.3. The lane area behind this border is no longer marked.

Also in step S7 of the method, the control objects 15 are determined, which have an influence on the driving behavior of the vehicle 1 in the first driving mode. These are displayed with a marker 18. In the present example, the control object 15.1, which represents the preceding vehicle, and the control objects 15.2, which represent the traffic light and the traffic sign with the speed limit, have an influence on the Driving behavior. In addition, the direction of movement of other determined road users are determined, which still have no direct influence on the driving behavior of the vehicle.

Their estimated driving trajectory is forecast and also indicated by means of arrow 15.4.

Furthermore, the driver can be displayed the planned movement trajectory of the own vehicle 1. The driver is thus conveyed the future planned vehicle behavior. Changes in the longitudinal guidance (braking and acceleration) and changes in the

Transverse guidance (lane change or similar) are conveyed to the driver by changes in the arrow display. Alternatively or additionally, the driver can also be displayed probabilities for certain driving maneuvers.

Through this representation of the rule objects 15 in the display area 3 of the HUD, the driver is informed that the system has actually recognized all dangers. This in turn serves to strengthen the driver's confidence in the fully automatic driving mode. Such a display is particularly important during the first fully automatic ride that the driver performs. Because if the driver does not trust the system, he can do it during the

fully automatic driving also does not devote to other activities.

In general, in the first driving mode, the driver's attention will be directed away from the driving action to the third display area 5 in the center console 6 of the vehicle 1. On this display surface 5, which is assigned to the infotainment system of the vehicle 1, the driver can finally watch movies, write e-mails, play games or engage in other ways.

It is therefore in step S8, while the first driving mode is turned on, on the third display surface 5, a third display element 17 is generated. The third display element 17 is divided into two areas A and B. In area A, the second display element 14, which was displayed on the second display area 4 in the second drive mode, is displayed. The meaning of the third display element 17 has, however, compared to the second

Display element 14 turned over. It now indicates when the first driving mode is no longer available. In addition, a time can be displayed numerically, which indicates the remaining time remaining to the availability of the first driving mode. The numerical display allows the driver to better estimate whether the time in which the first driving mode is still available is sufficient to watch a movie or finish an e-mail. The second display element 14 on the second display surface 4 can be hidden. In area B future maneuvers of the vehicle 1 are shown. These include not only strong changes to the longitudinal guidance (braking, acceleration) but also the display of planned lateral maneuvers (avoiding, overtaking).

In particular, step S7 and step S8 are executed simultaneously.

In step S9 of the method, it is determined that only a certain period of time remains during which the first driving mode is available. The specific period of time is

for example, in a time interval of one minute to 15 seconds. The particular

In particular, the time period should be long enough to give the driver time to realize that the first driving mode is not available any longer.

For example, five minutes before the first drive mode is no longer available, the density of displayed rule objects 15 could be reduced. This is to indicate to the driver that the vehicle is approaching a section of road in which it is no longer all

Can reliably process environmental information.

The driver must be made aware that he must again assume responsibility for the vehicle. It is therefore the third in step S10

Display element 17 shown changed. For example, it may start to blink.

Alternatively or additionally, an acoustic signal can be output, which makes the driver aware that the first driving mode is not available for a long time. In addition, the driver can also be displayed parameters that require a manual drive. For example, displayed lane markers may be flashing or flickering to indicate that they can no longer be recognized properly. Displayed traffic signs can be provided with a question mark, just to make it clear that the system can no longer recognize them clearly.

This shows the driver the limits of the system. This too is a confidence-building measure. The driver can thereby learn to estimate himself when a ride in the first driving mode is possible and when not.

If the vehicle 1 changes back to the second driving mode in which the driver drives the vehicle 1 again, the procedure is started from the beginning.

The display in the first display area 3 is intended in particular to strengthen the driver's confidence in the system. However, the trust must first be built. For this purpose, an uncertainty level of the driver can be determined by means of a driver condition sensor system. In particular, a viewing time on the first display area 3 of the HUD during the first drive mode can be determined. If the driver gains confidence in the system, the viewing time on the display area 3 of the HUD will be shorter. This can be detected by the driver condition sensor. If it has been determined that the degree of uncertainty has fallen below a certain limit, the display in the first display area 3 of the HUD can be hidden.

The display can then be re-displayed, for example, depending on the maneuver. This means that suitable rule objects 15 and movement trajectories are always displayed on the display surface 3 of the HUD when a maneuver (evasive maneuver,

Overtaking maneuver) is imminent. This also strengthens the driver's confidence in the system.

The first driving mode may also be a semi-automatic driving of the vehicle 1. The driver is then shown when certain driver assistance systems can be used and when not. However, since in a semi-automatic drive, the driver does not completely give the driving responsibility, display elements are displayed on the first display surface 3 of the HUD and the second display surface 4 of the FPK 8. The display on the third display area 3 is then not necessary because the driver does not pay any attention to this.

The method according to the invention can also be carried out only partially.
