The current vehicle driving state is determined, at least one boundary condition for the state is determined enabling safe driving through the section of route in front of the vehicle and at least one route-dependent information item is generated (12) if the current state does not fulfill at least one boundary condition. Independent claims are also included for the following: an arrangement for providing warning information dependent on the route to a vehicle driver.

Description

The invention relates to a method for providing route-dependent warning information to the driver of a Motor vehicle according to the preamble of claim 1 or with a device for providing routes dependent warning information according to the preamble of the patent Proverbs 9

DE 197 25 075 A1 describes a device for providing information about the specified maximum level speed in a motor vehicle known. Accordingly, with With the help of a location device of the respective routes traveled section can be determined. The respective route sections are the prescribed maximum levels stored in a memory speeds associated with the respective by the Or determined system section and the Drivers are displayed. With this device the driver should to be supported, the prescribed maximum to maintain speed.

However, such a device is only for route sections can be used for which maximum speeds are known. One makes sense especially when driving on a curved route prescribed maximum speed sustainably for safety in road traffic. The maximum speed is not knows, there is a safety risk if the driver uses the Speed is not maintained by the most attentive driving style. The maximum speeds can be according to the known Einrich the vehicle from the outside, for example via data transmission devices,  communicated and thus updated, however it is necessary to do this, the maximum speeds of individual Determine route sections in advance before they are available can be provided. Surface such a determination Performing opaque is extremely complex and costly.

For sections of the route for which there are no maximum speeds are known, the system described above is not a settable. A security risk remains in particular when driving through winding routes.

The object of the invention is a method and Device for providing route-dependent goods to provide information to the driver of a motor vehicle, that supports the driver, one before Vehicle lying route with adapted speed ability to drive safely.

This object is achieved by a method according to Pa claim 1 and by a device according to claim 9 solved. Advantageous further developments result from the Un claims.

In the method according to the invention, the course of the the vehicle to be traveled at least be partly forward-looking and at least relative to the current one Vehicle position determined. Based on the course of the before Vehicle lying route can thus provide information about it be made available whether the driver is the motor vehicle for example by a right or left turn or egg to control a roundabout, or whether to cross an intersection cross is. This is particularly useful when the route in front of the motor vehicle is not complete dig is visible.

In addition, the current driving state of the motor vehicle determined. For example, the current speed  or acceleration of the motor vehicle. These values are important for assessing whether the vehicle is current Driving condition can be maintained if, for example, the before Vehicle is traveling through a curve.

So that the motor vehicle can also safely negotiate the curve, d. H. due to the intended lane without course deviations can withstand centrifugal forces, for example, is at least one limit condition for the driving state in front the route of the motor vehicle is determined. This Boundary condition can be, for example, a speed with which a comfortable and safe driving through a curve is possible in the course of the route. In particular, the Querbe occurring in curves with a small radius of curvature acceleration values at higher cornering speeds are not be very high while the lateral acceleration values at long more tight corner turns may be higher.

To give the driver an indication of his driving behavior for example regarding speed selection or acceleration cleaning behavior to be traversed by the motor vehicle Adjusting the route section will require at least one route Generated warning information generated when the current driving the at least one limit condition was not met. The A driver does not become one before driving through Visible, tight curve warned so that it could be comes to slow down his motor vehicle or speed decrease by gas removal.

The at least one limit condition is derived from the course the route to be traveled by the motor vehicle th geometric dimensions of the front of the motor vehicle the area determined. The geometric dimensions can can be taken from the determined route. If in there is a curve, for example, in the area to be traversed, can the at least one limit condition depending on the curve be determined. With one in front of the vehicle  Intersection based on its geometry in the road guidance an order is recognized as such, the boundary condition can be a reduced speed for approaching the intersection include.

However, the at least one limit condition can also be from depend on the condition of the road. A motor vehicle behaves for example on wet, snowy or icy Road completely different, like on a dry road surface. Around To increase security, the at least one limit condition in consideration of the condition of the road surface the area of the vehicle to be driven through Distance to be determined.

One of the driving dynamics used to determine the current Driving state can be used is the current Fahrge speed, which can be easily determined. For the min at least one limit condition can be a target speed for the safe passage of the Be lying in front of the motor vehicle range of the route to be traveled can be determined. In the target speed determination flow the available standing information about the one in front of the motor vehicle Driving route - and especially over the immediate one existing route area - and the condition of the road on. The current driving speed can be easily with the Compare target speed. If the current Fahrge speed is higher than the determined target speed, the warning information is generated. For example, the Driver then give a warning when he's about to inflate driving into a curve, for example and risk being carried out of the curve.

The driver can receive the warning information optically, acoustically or be displayed haptically. A visual display in the field of vision of the driver informs an attentive driver about future dangers related to the route. An acoustic signal that can also be done in addition to the visual display  a driver who is briefly distracted and the optical one Display is not in view. In addition, the driver can through haptic information, which is a "kick" to the Pedals can be warned, increasing attention the driver is increased even further.

The warning information is the determined in front of the motor vehicle lying area assigned to the route to be traveled. For example, when cornering in a right turn is in progress, an informative pointing to a right turn on generated. Such warning information can be in a first Information step are visually displayed to the driver. In egg In a second information step, the information can additionally be acoustically displayed when the driver is within a predetermined period of time not on the optical warning information responds. Such a reaction can be that the Driver the current driving speed by pedal intervention right induced. This gradually informing the driver largely ensured that the driver reali the warning siert.

However, the acoustic warning information can also be generated be when the motor vehicle at a predetermined kri table location in the route to be traveled. If the driver does not respond to the visual information and that Vehicle already in the critical area of the front of the vehicle lying route is penetrated by the acousti warning the driver to react immediately. This increases driving safety considerably.

According to a further basic idea of the invention, the driving longitudinal movement are influenced such that the current Driving speed is reduced when the driver is inside a further predetermined period of time neither on the optical still reacts to the acoustic warning information. So it will a driver-independent intervention in the vehicle's longitudinal dynamics performed. Such an intervention can then also be brought about  be when the motor vehicle at a predetermined kri table location in the route to be traveled. As The current vehicle can react to the impending danger speed can be reduced without the driver himself takes hold. This will ensure that the front of the force vehicle lying critical route area also si is driven through when the driver receives the warning information ignored.

After driving through the area in front of the motor vehicle the route to be traveled can be another intervention in the longitudinal control of the motor vehicle are made, so that the current driving speed on the driving speed speed is increased before passing through the critical area. The This measure brings a gain in comfort because the driver does not have to increase speed again through personal intervention.

According to the invention, there is also a device for providing of route-dependent warning information to the driver nes motor vehicle specified. This device comprises a Output device for the warning information and one with a Storage device for roadways connected electronics cal locating device, which the course of the force vehicle to drive through at least in some areas looking ahead and at least re the current vehicle position determined relative to the route.

It is a device for determining the vehicle Actual speed is provided. There is also a limit provision determination device provided, which from the current len vehicle position relative to the route under Be taking into account at least that in the storage device for Geometric dimensions of the road course can be stored in front of the motor vehicle the area to be driven through Travel distance determined a target speed that a safe Res passage through the area.  

The device has one with the locating device acting evaluation device, which the target speed compares the speed with the actual speed pending warning information generated when the actual speed is higher than the target speed and with the output direction is connected to the route-dependent warning to provide formations.

With the device according to the invention, it is possible to to warn drivers of a motor vehicle with one of the be above course of the route inappropriate speed entering a critical area of the route. A un adjusted speed can on the one hand driving safety endanger sustainably and on the other hand the driving comfort by Auf uncomfortable centrifugal forces occur in a winding route ver affect run.

The boundary condition determination device can be with a Vehicle arranged lane texture Detection device connected, so that the target speed considering the nature of the road in front of the motor vehicle the area to be driven through Route can be determined. The road surface texture Determining device can be designed so that it for example, can detect road wetness and icing.

According to a principle of the invention, the output can be direction be connected to an optical display device, which represents the warning information in the form of pictograms, the area lying in front of the motor vehicle moving route are assigned. Depending on the form of the to drive through a route area on this route Warning area indicative area can be generated. This route-dependent optical information can be in the form of pictograms or icons in a storage device be saved so that a set of different icons It is stored which specific route course areas are assigned  can be. With such an optical display the driver can easily refer to the Expression of the critical loading lying in front of the motor vehicle be closed.

To give the driver an even more intense warning the output device with an acoustic playback device be connected. This provides the warning information in the form of voice signals, driving noises or the like acoustic Signals. So the attention can be given by acoustic signals speed of the driver on the display device impending critical route area be directed. In addition, the Information can be passed on directly to the driver without he has to look at the display device. If the driving testimony immediately before the critical route area is, for example, by playing "tire squeal" be alerted to an upcoming curve. The driving route-dependent acoustic information is stored in a Storage device deposited.

The output device can be loaded with at least one driver Actuable vehicle control element coupled, which with a generating device for haptic signals connected is. The haptic signals can be issued when a warning mation at least transferred to the vehicle control element the. To the driver's attention even more to a be to steer the above critical route situation with this measure, for example, "kick movements" or move conditions on an accelerator pedal, such as the accelerator pedal.

With the help of an adjustable timer, which with the output device is coupled, an enable signal to provide the optical, acoustic or haptic route-dependent warning information depending on the time be. Thus, for example, there is a gradation in time between visual and acoustic and / or haptic display  possible to give the driver different stimuli for the Record and implement the information provided on bie Ten. Furthermore, the time switching element of time Set the room in which the warning information is displayed before entering the critical route area shall be.

According to yet another basic concept of the invention, the Evaluation device with a device for influencing the Longitudinal vehicle movement can be coupled to the actual speed at least to reduce the target speed. The current The actual speed can then be reduced if the driver of the motor vehicle within a predetermined ten preselectable time on the time switch element from availability len from optical, acoustic or haptic routes pending warning information on the output device is not rea greed, d. H. the actual speed is not actively reduced.

The device can also be used to influence the length of the vehicle motion connected to the electronic tracking device be to the actual speed at least to the target speed to reduce speed when the locating device determines that the motor vehicle is at a predetermined critical Location is in the route to be traveled.

By the longitudinal movement of the vehicle regardless of the intervention of the Driver, however, depending on time or location, reduced speed can be adorned, it is possible to increase the risk reduce the vehicle to one in front of the vehicle lying section of the route inappropriate, too high speed into the critical area.

The device for influencing the longitudinal movement of the vehicle can be designed after driving through before Motor vehicle lying area to be driven stretch the current driving speed to the driving speed increase before driving through the area. Hereby  the driver can be relieved of the task of driving accelerate stuff by pedaling. One at a time Cruise control or a speed control device of the Motor vehicle selected driving speed can after Durchfah critical area.

All in all, the inventive method and the device according to the invention, the driver, one before Vehicle lying route with adapted speed ability to drive safely.

Based on the description below in connection with the accompanying drawings will show further advantages, features and Details of the invention are clearer.

Fig. 1 shows a sketchy partial view of the dashboard 10 of a motor vehicle from the perspective of a driver, wherein the op tical display device 12 of the device according to the invention is shown in one embodiment as a schematic diagram.

Referring to Fig. 1, the basic idea of the invention is described below with reference to execution form a corner.

As shown in FIG. 1, the driver, when looking through the windshield, recognizes the area 14 of the route that lies in front of the vehicle. However, the driver can not see with sufficient certainty that in this area 14 an unrecognizable right turn 18 adjoins the overviewable road section 16 .

The driver should be informed about this right-hand curve 18 if driving safety is not ensured due to the route ahead of the vehicle while maintaining or increasing the current speed. The condition of the road surface with regard to wetness, ice and snow should also be taken into account.

To display such information, an optical display device 12 in the form of a screen for the optical representation of a symbol 20 or icons and on the other hand an acoustic display device 22 in the form of a loudspeaker for the reproduction of "spoken text" or acoustic warning signals are provided . A selection of possible symbols 201 a to 205 b is shown in FIG. 2, which will be described in more detail later.

The display device 12 can alternatively in a (not shown) instrument cluster or in a (not shown) on display device in the vehicle center console z. B. integrated in the screen of a navigation system, which can display not only the pictograms but also other information of interest to the driver. Alternatively, the acoustic display device 22 can also be integrated in a vehicle speaker system (not shown) of the audio system.

The driver is informed in information levels about the area of the route in front of the motor vehicle. A curve region of such a route to be traveled through by the motor vehicle is shown in FIG. 3, to which reference is made below.

In the first information stage, the driver is optically warned by the display of a symbol 20 on the optical display device 12 if the current vehicle speed can lead to a critical situation (e.g. driving too fast on a curve). This first information level is triggered for example at position A shown in FIG. 3. Position A and other positions in the route can be determined, for example, by a GPS system in conjunction with an electronic road map.

In a subsequent second information stage, the driver is additionally informed by voice output via the acoustic display device 22 if the current vehicle speed can lead to a critical situation and the driver does not respond to the icon 12 . This can be the case with position B shown in FIG. 3, for example. The second information level is triggered when position B determined by the GPS system is reached. Alternatively, however, the elapse of a vehicle speed-dependent period of time that the motor vehicle needs to get from position A to position B can trigger the second information stage.

In a third information stage, the vehicle speed is automatically reduced if the current vehicle speed can lead to a critical situation, the driver does not react to the icon 12 and a critical situation is imminent. This can be the case, for example, at position C shown in FIG. 3. The reaching of the position C determined by the GPS system triggers the third level of information. Alternatively, however, the lapse of a time-dependent time period, which the motor vehicle needs to get from position A to position C, can trigger the third information stage.

In a fourth information level, the critical speed automatically accelerates back to the original speed. This can be the case, for example, at position D shown in FIG. 3. Reaching the position D determined by the GPS system triggers the third information stage.

In addition, the driver can use both the optical and with the acoustic warning information about the distance to the critical area, approximately until reaching position C, in be formed.

The device for providing route-dependent Warning information can be found on a keyboard (not shown) or activate and parameterize a steering wheel operating system. You can also use the keyboard or a (not shown) "slider" adap the information frequency be animals. This makes an adjustment to the driver's request enables.

The information frequency can be increased or decreased in several ( 5 to 15 ) stages by the driver using the slide controller, which means that the driver is informed less frequently. A setting is selected as the default value which a "normal driver" does not have to change.

The device is in the middle position of the slider posed that the driver is always over in dangerous situations the route in front of the vehicle is informed. With the middle slider position, the device is one asked that the driver not too often over the route ver is informed and the information is perceived as annoying det. If the driver changes the position of the slider, see above it is saved and after the ignition is switched OFF / ON used again.

The information frequency can also vary depending on the driving behavior of the driver. Sporty drivers, for example are not warned too often, whereas thoughtful drivers used to and be warned more often as sporty drivers. With help of a "Learning system" is the information frequency by the Driving behavior of the driver adapted to the driving style of the Driver. So there is a driver type recognition uses.

The route-dependent warning information is generated in particular from the point of view of driving safety. However, the driver can also use the warning information to achieve a "comfortable" driving style when driving through critical areas. A comfortable driving style, for example when cornering, results for the driver and the passengers in a motor vehicle from a "comfort curve" as shown in FIG. 4. Here, the lateral acceleration of the driver or passengers against the driving speed is carried. According to the "comfort curve" should occur at a high Fahrge speed only a little lateral acceleration so that the occupants of the motor vehicle feel comfortable. This means that the driver should take care to adapt the speed to the curve radius of the upcoming curve when driving through a curve in order to achieve a comfortable driving style. Curves with a large curve radius can be driven through faster than curves with a small curve radius, without the occupants finding this uncomfortable.

FIG. 2 shows possible representations of the route-dependent pictorial characters optically displayed on the display device shown in FIG. 1, the left column each showing pictorial characters from a German character set and the left column showing the corresponding pictorial characters from a US character set.

A selection of possible symbols 201 a to 205 b is described below with reference to FIG. 2.

With the reference symbol 201 a is the German symbol for "left turn" and with 201b the corresponding American symbol for "left curve". The symbols are based on the German (European) or (US) American traffic signs, which are familiar to the German or American driver. It is therefore easy for the driver to whom such a symbol is presented on the display device 12 to ascribe a route-related meaning to the illustrated symbol. The displayed "traffic sign" for Attention left turn "informs the driver about an upcoming left turn in an understandable way.

The reference symbols 202 a and 202 b denote the symbols from the German or American symbol set, which warn of an impending S curve by being displayed on the optical display device 12 . The reference numerals 203 a and 203 b accordingly designate the German or American symbol for optical warning information before an intersection. With 204 a and 204 b are the specially created (unofficial) German or American symbols for a roundabout and with 205a and 205b the German or American symbols for a warning of danger of skidding.

There are two complete picture sets for Europe and the United States United States of America, which symbols for all possible dangerous conditions in the course of the route hold. The selection of the corresponding image character set rich depends on the country they have traveled through. To avoid confusion with To induce drivers, pictograms are always pre-selected for the driver which corresponds to the national traffic signs voices. In order to be able to select the correct image character set, Country information is always provided with the help of GPS Systems or existing digital road maps.

The acoustic information output from the acoustic display device 22 shown in FIG. 1 are made up of speech modules which are combined to give specific information. For German texts, for example, this can be "Caution" with a pause, "Caution" with a pause, "Right-hand bend", "Left-hand bend", "Curvy" or similar language-specific language modules. Alternatively, complete sentences or sentence fragments can also be stored, e.g. B. "Attention left turn!".

In FIG. 5 is a simplified schematic diagram of an embodiment of the apparatus is shown for providing route dependent warning information. A speed meter 24 determines the current driving speed. A GPS system 26 with a road map electronically stored in a memory 28 determines the current position of the vehicle in the route determined by the road map. A road surface determining device 30 with a rain sensor (not shown) and a temperature sensor (not shown) or other sensors determines whether the road is dry, wet, icy or snowy. The GPS system 26 and the road surface determining device 30 are connected to a device 32 for determining a desired speed for the route area to be traveled through. The determined target speed is determined from the position determined by the GPS system 26 using the electronic road map 28 relative to a critical route area, the stored geometric dimensions from the route area and the condition determined by the road surface determination device 30 .

The speedometer 24 and the device 32 for determining the target speed are connected to an evaluation device 34 which compares whether the current driving speed is greater than the target speed. The evaluation device 34 is connected to an output device 36 in order to generate warning information when the current driving speed is greater than the target speed.

The output device 36 is connected to an optical display device 12 , which in turn is connected to a memory 38 for optical symbols. Depending on the route area determined from the electronic road map 28 , a specific icon for warning the driver is displayed on the optical display device 12 in a route-specific manner. An adjustable time switch member 40 is connected to the visual display device 12 and an acoustic display device 22 after a certain period of time an audible warning information to the acoustic Anzeigeeinrich tung output 22nd The route-specific acoustic warning information is stored in a device 42 connected to the acoustic display device 22 . The acoustic display device 22 receives a sequence of language modules coded language-independently and outputs the warning information in the language, which is also stored in the memory 42 .

In addition, the acoustic display device 22 is connected to a device 44 for generating haptic signals which, for. B. transmitted to an operating pedal 46 of the motor vehicle.

The timer element 40 is also connected to a device 48 for influencing the longitudinal movement of the vehicle, in order to reduce the driving speed of the vehicle after a period of time has elapsed on the timer element 40. The device 48 for influencing the longitudinal movement of the vehicle is additionally coupled to the target speed determining device 32 and the speedometer 24 to ensure that the current driving speed has been reduced at least to the target speed. Furthermore, the device 48 for influencing the longitudinal movement of the vehicle is connected to the GPS system 26 and the electronic road map 28 in order to reduce the driving speed when a critical position is reached.
