Description

The invention relates to a method for operating a motor vehicle. The invention also relates to a motor vehicle and an information and / or guidance system.

A large number of assistance systems are known which support a driver by providing information or driving interventions when performing certain driving tasks. With regard to the parking of motor vehicles, it is known, for example, to support the driver with distance warning devices or even to carry out fully automated parking.

When parking the motor vehicle, the aim is to prevent a driver from unauthorized parking the motor vehicle in a position at which this is subject to a fine. Assistance processes are also known for this task. For example, the pamphlet teaches DE 10 2010 020 135 A1 the use of a traffic sign recognition device to recognize no parking signs. If the vehicle is parked in a no-parking zone marked in this way, a corresponding message is output.

The disadvantage of this procedure is that not all areas can be recognized on the basis of traffic sign recognition alone in which parking is not to be required. In some cases, for example, the sign indicating the no-parking sign can be difficult to see, or a no-parking sign can result from other traffic regulations without corresponding areas being explicitly identified by a sign.

As an alternative or in addition to recognizing traffic signs, areas in which parking is prohibited could be stored, for example, in a digital map that is held in the motor vehicle itself or is made available to the vehicle by an external device. Providing such maps for the entire transport network of a country or even worldwide, however, is extremely complex, so that such an approach only appears expedient for certain areas, for example metropolitan areas.

The invention is therefore based on the object of improving the support of a user in avoiding parking a motor vehicle in areas in which parking is not permitted.

• - Ermittlung einer potentiellen Parkposition für das Kraftfahrzeug,
• - Ermitteln wenigstens einer Umgebungsinformation, die jeweils eine Art eines zu der Parkposition führenden oder die Parkposition umfassenden Verkehrswegs und/oder eine Geometrie dieses Verkehrswegs und/oder von dessen Berandung und/oder einen Abstand der Parkposition zu einem weiteren Verkehrsweg betrifft,
• - Auswerten wenigstens einer Auslösebedingung, deren Erfüllung jeweils von der Umgebungsinformation oder wenigstens einer der Umgebungsinformationen abhängt,
• - Ausgabe eines Hinweises an einen Nutzer des Kraftfahrzeugs und/oder zumindest teilautomatisiertes Führen des Kraftfahrzeugs zu einer von der Parkposition beabstandeten Position, wenn die Auslösebedingung oder wenigstens eine der Auslösebedingungen erfüllt ist.

The object is achieved according to the invention by a method for operating a motor vehicle which comprises the following steps:

• - Determination of a potential parking position for the motor vehicle,
• - Determination of at least one piece of environmental information relating to a type of a traffic route leading to the parking position or comprising the parking position and / or a geometry of this traffic route and / or its boundary and / or a distance between the parking position and a further traffic route,
• - Evaluation of at least one trigger condition, the fulfillment of which depends on the environmental information or at least one of the environmental information,
• Output of a message to a user of the motor vehicle and / or at least partially automated guidance of the motor vehicle to a position spaced from the parking position if the trigger condition or at least one of the trigger conditions is met.

The method according to the invention makes it possible to avoid parking in no-parking areas by providing appropriate information or automated guidance, even if these areas are not explicitly marked by a sign or the like. Corresponding parking bans are usually regulated by laws, ordinances or the like, for example in Germany by the road traffic regulations. In the context of the invention, it was recognized that triggering conditions or rules can be defined for a large part of corresponding rules, which can decide on the basis of the environmental information mentioned whether corresponding prohibitions are relevant for a certain potential parking position.

A relatively large number of modern motor vehicles already have high-performance environmental sensors that can be used to record the corresponding environmental information. In addition or as an alternative, they can be taken from digital map data, for example from a map of the navigation system of the motor vehicle, without separate information relating to the permissibility of parking having to be added for this purpose. The method according to the invention can thus be implemented with very little additional technical effort.

The improved assessment of the admissibility of parking in a potential parking position is achieved by evaluating environmental information that does not directly relate to the admissibility of parking, for example the presence of marked prohibited areas in digital maps, no parking signs or the like, but information about the surroundings of the potential parking space Parking positions with which depending on predetermined rules, so the Trigger conditions, possible resulting parking bans can be checked.

If at least parts of the information about the surroundings are to be taken from a digital map, it is advantageous to know the position of the potential parking position with a high degree of accuracy in the coordinate system of the map data. For this purpose, for example, the position of the motor vehicle can be recognized precisely to the lane on the traffic route. This can be achieved, for example, by further refining an initially provisional position, which can be based on GPS data, for example, by comparing features of the surroundings detected by a motor vehicle sensor system with features stored in the map data. Appropriate approaches are known in principle in the prior art and should therefore not be explained in detail.

If the potential parking position is recognized, for example, by recognizing maneuvering movements of the motor vehicle for parking, engaging a parking gear or applying a handbrake or switching off the engine or the like, the position of the potential parking position essentially corresponds to the motor vehicle position. Potential parking positions and their location in relation to the motor vehicle can, however, also be recognized by the motor vehicle's sensor system before the parking process.

If several trigger conditions are evaluated, the different trigger conditions can evaluate different subsets of the environmental information. In the simplest case, a trigger condition can only evaluate one of the environmental information. However, several pieces of information about the surroundings can also be evaluated jointly by a trigger condition.

The evaluated trigger conditions can preferably be configured or adapted in a simple manner. In this way, it can be implemented, for example, that different trigger conditions are evaluated for a use of the motor vehicle in different countries in order to support the driver in complying with local regulations. In addition, in this case the trigger conditions can be adjusted as required in the event of changes in the law or on the basis of user experience.

This can be implemented, for example, in that the triggering conditions or rules specifying the triggering conditions are stored in a database which can be stored locally in the motor vehicle or on an external device. In principle, it is possible here to store each of the trigger conditions as executable program code in the database, with the environmental information being able to be made available via a defined program interface. On the other hand, corresponding rules or trigger conditions can under certain circumstances be implemented or maintained more easily if they are defined in a formal language that describes the corresponding conditions or rules and which is interpreted or compiled as required by an interpreter, for example. For example, comparison operations can be defined here which check whether certain information about the surroundings has a certain value or is greater or less than this, and the results of corresponding comparison operations can optionally be linked by logic operations. For example, a trigger condition can evaluate whether a parameter describing the type of traffic route has a certain value or whether the distance to another traffic route, for example to a junction or intersection, falls below a limit value.

An at least partially automated, in particular fully automated, guiding of the motor vehicle to a distant position can be particularly useful if it is recognized that the potential parking position is not suitable for parking the motor vehicle, but other suitable parking positions or at least potentially suitable parking positions are known in the vicinity . In this case, the motor vehicle can be automatically guided to a corresponding position immediately or after a corresponding confirmation by the user. Here it is possible, for example, to use known approaches to parking space management. For example, it is possible to determine for known, potentially usable parking positions whether they are occupied by another motor vehicle, and to provide corresponding receipt cards to the individual motor vehicles, for example via a central server, a cloud solution or the like.

At least one of the triggering conditions can depend on at least one further parameter in addition to the environmental information mentioned. For example, it is possible, based on the type of traffic route or another of the parameters mentioned, to recognize that parking is only permitted at certain times and / or for a maximum parking period and / or only for certain vehicle types or the like. Correspondingly, these variables can be taken into account within the triggering condition. It is also possible here to request additional information from a user, for example via an operating interface of the motor vehicle, a communication device of the user or the like. For example, if it is recognized on the basis of the information about the surroundings that a parking period is relevant, a Users are asked for an intended parking duration, which is taken into account when evaluating the trigger condition.

The output of a message to the user can serve, for example, to inform the driver about a presumably existing stopping or parking prohibition. This can be done while stopping or parking or after completing this maneuver. Such a notice can be supplemented, for example, with a recommendation regarding the next possible stopping or parking zone. Here, for example, as explained above, known assignments of corresponding areas can be taken into account. In addition or as an alternative, the notice can include a reason why there should be no stopping or parking. On the one hand, this can increase user acceptance and, on the other hand, it enables a user to decide for himself whether the automated evaluation of the triggering conditions could potentially have led to an incorrect assessment of the potential parking position.

The notification or at least partially automated guidance of the motor vehicle to another position can be suppressed if it is recognized that the stopping or parking of the motor vehicle is an emergency stop maneuver, a breakdown or the like, so that it is not possible to continue driving or is expedient.

Notes can be given in a variety of ways. For example, a display can be used in the vehicle interior. The potential parking position and information as to whether it can be used or whether it cannot be used can be displayed, for example, on a schematic map display or as an overlay on a camera image. It is also possible to project information, for example by means of a high-resolution headlight, onto the roadway or, for example by means of a head-up display, onto the windshield. Sound or voice output for information output are also possible.

The fulfillment of the trigger condition or at least one of the trigger conditions can depend on whether the determined type of traffic route is an expressway or a motorway or a forest path or a one-way street or a street outside a built-up area or in a residential area or in a traffic-calmed zone. For example, a trigger condition can be fulfilled or can only be fulfilled if the potential parking position is on an expressway or motorway or a street outside a built-up area, since parking is typically not permitted there. Likewise, a trigger condition can be fulfilled or can only be fulfilled if the parking position is directly adjacent to an expressway or motorway. This can be used, for example, to identify hard shoulder or emergency stop or breakdown bays in which parking is typically not permitted, except in the event of a breakdown. In some countries, parking on forest paths or in traffic-calmed zones is also not permitted.

Other types of traffic routes can also mean that parking is not permitted under certain conditions. In the case of a one-way street, for example, it is useful if the trigger condition additionally evaluates an alignment of the motor vehicle with respect to the direction of travel of the one-way street, since parking against the direction of travel is not permitted in many countries. Certain parking restrictions may also apply in residential areas, in particular for combinations or vehicles with trailers. In Germany, for example, carriages are forbidden to park in residential areas between 10 p.m. and 6 a.m. and on Sundays and public holidays.

The fulfillment of the trigger condition or at least one of the trigger conditions can depend on whether the determined geometry of the boundary of the traffic route describes a lowered curb. In many countries, parking next to lowered curbs is not permitted, so that the trigger condition can be met, for example, if the potential parking position is located directly next to a lowered curb.

Depending on the geometry of the traffic route, a distance between the potential parking position and a curve in the traffic route and / or a curve radius of the curve can be determined, the fulfillment of the trigger condition or at least one of the trigger conditions depending on the distance to the curve and / or on the curve radius . The trigger condition can in particular be fulfilled when the curve radius and the distance each fall below a limit value. For example, a parking ban in the area of sharp bends can be taken into account in this way.

Depending on the geometry of the traffic route, a measure of the visibility of the potential parking position from at least one position on the or another traffic route that is spaced from the potential parking position can be determined, the fulfillment of the trigger condition or at least one of the trigger conditions depending on the degree of visibility . The measure of visibility can, for example, only take into account the course of the further traffic route or route. In particular if the area of the potential parking position is through a The motor vehicle-side sensor system is detected, but buildings and / or vegetation in the area of the or further traffic route can also be taken into account. Since parking at parking positions that are not clearly visible can be problematic for other road users and is therefore also prohibited in some countries, the trigger condition can be fulfilled, for example, if the potential parking position is difficult to see.

The fulfillment of the triggering condition or at least one of the triggering conditions can depend on a distance from another traffic route, which is a merging or crossing road or a traffic route for a rail-bound means of transport or a cycle path. For example, the trigger condition can thereby be fulfilled if the potential parking position is too close to an intersection or an intersection, for example if it is less than 5 m away from an intersection or an intersection. Parking on cycle paths or in the rail area of a rail-bound means of transport should also be avoided and is often not allowed. Correspondingly, minimum distances can be maintained to such traffic routes by means of a corresponding trigger condition. Corresponding rail-bound means of transport are, for example, trains, trams and the like. Other traffic routes, in particular rails, can be recognized, for example, on the basis of digital map data, for example taking into account a GPS position of the motor vehicle, and / or by a sensor system on the motor vehicle, in particular a camera. For example, barriers or traffic signs can be recognized that indicate the presence of traffic routes for rail-bound means of transport, so that the rails themselves do not necessarily have to be recognized in order to evaluate a corresponding trigger condition.

The fulfillment of the trigger condition or at least one of the trigger conditions can additionally depend on a vehicle type of the motor vehicle and / or on the presence of a trailer on the motor vehicle and / or on a current time and / or on a probable parking duration. The consideration of a vehicle type or the presence of a trailer can be particularly relevant if parking bans are to be taken into account, which are especially relevant for trailers. As already mentioned above, for example, it is forbidden to park carriages in residential areas in Germany at certain times.

When parking teams, it must also be taken into account that parking teams in the same position for longer periods of time, for example in Germany for more than two weeks, may be prohibited. An indication or an at least partially automated guidance of the motor vehicle to a distant position can thus also take place if a further trigger condition is met, which depends, in particular exclusively, on a vehicle type or the presence of a trailer and on an expected parking time.

A probable parking time can be determined in these or other cases, for example, by asking the user about a planned parking time. Alternatively, a parking duration can be forecast, for example, by evaluating a previous parking behavior for the respective motor vehicle or the respective driver. Approaches to forecasting future driving or parking behavior on the basis of previous driving are known in principle and should not be explained in detail.

The triggering conditions can each correspond to a rule that excludes the admissibility of parking under certain conditions, in particular a traffic rule. Corresponding rules and thus the basis for the triggering conditions can be found in Germany, for example, in the road traffic regulations or other relevant regulations. For example, different rules may apply in different countries, sometimes even in different federal states.

It is therefore advantageous if, on the basis of a detected position of the motor vehicle, it is determined in which of several geographical areas the motor vehicle is located, each of the areas being assigned a set of triggering conditions that are evaluated when the motor vehicle is in the respective area . For example, the relevant triggering conditions or to be evaluated can be taken from a database as a function of the determined area or, as a function of the area, one of several databases can be selected that provides the corresponding triggering conditions or rules on which they are based.

For example, only one address, for example an IP address, of a relevant database external to the vehicle for the triggering conditions or the rules on which they are based can be known for each country or each relevant geographic area, and the triggering conditions or rules can be reloaded from this address as required. Instead of selecting the corresponding database on the motor vehicle side, this can also be done outside the vehicle. For example, depending on the radio cell via which the motor vehicle is connected to a communication network communicated, a request to a database comprising trigger conditions or rules can be automatically forwarded to a database that is assigned to the same geographical area as the radio cell.

The potential parking position can be determined as a function of sensor data relating to a driver of an interior sensor of the motor vehicle and / or as a function of an actual value and / or a change in a speed and / or a steering angle and / or an engaged gear and / or an operating state of an engine and / or an ignition can be determined. In the simplest case, the variables mentioned can be evaluated in order to determine whether parking is currently taking place and, in this case, the current position of the motor vehicle can be selected as the potential parking position. For example, a change in the viewing direction and / or a movement of the upper body of a driver can be used to recognize that the driver is looking for a parking position or is trying to maneuver into a parking position. When parking, a low speed is typically selected. Characteristic changes in the steering angle or frequent changes between forward and reverse gear can also occur. The parking of the motor vehicle in a parking or stopping position can be recognized, for example, when an ignition or an engine is switched off, the speed is zero for a longer period of time, a parking gear is engaged or the like.

Potential parking positions can also be recognized before the motor vehicle reaches them. For example, an interior sensor, for example an interior camera, can be used to detect a direction of view of the driver if the aforementioned motor vehicle parameters indicate that a parking is taking place or is imminent. From data from the environment sensors, map data or the like, several potential parking positions in the vehicle environment can then be recognized, for example, and the most relevant of these can be selected based on the viewing direction.

In addition to the method according to the invention, the invention relates to a motor vehicle that is set up to carry out the method according to the invention. The motor vehicle can have an environment sensor system, for example several cameras, on the basis of whose data the information about the environment can be determined. In addition or as an alternative, the motor vehicle can have a memory device that stores a digital map and / or communicates via a communication device with a device external to the vehicle that provides the digital map data in order to determine information about the surroundings therefrom. Digital map data and sensor data can also be evaluated together to determine the surrounding information. The determination of the respective environmental information and the evaluation of the respective trigger condition can be carried out by a control device of the motor vehicle.

Triggering conditions or rules that they specify can be stored in a database on the vehicle or can be called up from a device external to the vehicle. The vehicle can include an output device for outputting a message to a user. Examples of corresponding output devices have already been mentioned at the beginning. Additionally or alternatively, the motor vehicle can have a driver assistance system that is set up for at least partially automated guidance of the motor vehicle and that can be activated to guide the motor vehicle to the position spaced from the parking position when the trigger condition is met.

In addition, the invention relates to an information and / or guidance system for outputting information to a user of a motor vehicle and / or for at least partially automated guidance of the motor vehicle, wherein the information and / or guidance system comprises, in addition to the motor vehicle, a device external to the vehicle, wherein the motor vehicle and the vehicle-external device are set up to jointly carry out the method according to the invention, wherein the trigger condition or at least one of the trigger conditions is evaluated by the vehicle-external device and / or wherein the vehicle-external device is set up to provide a data set to the motor vehicle, which the trigger condition or at least one describes the trigger conditions.

Even if the trigger condition is evaluated externally to the vehicle, the output of a message or the at least partially automated guidance of the motor vehicle when the trigger condition is met is preferably carried out by a control device of the motor vehicle set up for this purpose. If the trigger condition is evaluated externally to the vehicle, it can be sufficient if the motor vehicle only transmits its position or the position of the potential parking position to the device external to the vehicle. Ambient information can then be taken from digital map data, for example. In addition, the motor vehicle can, under certain circumstances, transmit sensor data from sensors on the motor vehicle side and / or environmental information determined from these to the device external to the vehicle, which data are taken into account in the evaluation of at least one trigger condition.

On the other hand, it is also possible for all trigger conditions to be evaluated on the motor vehicle side. Surrounding information can also only be determined on the motor vehicle side. However, it is also possible that additional information about the surroundings, based for example on digital map data, is provided by the device external to the vehicle or that the device external to the vehicle provides digital map data or the like, on the basis of which at least parts of the information about the surroundings are determined.

Providing a data record to the motor vehicle that describes at least one of the triggering conditions can be particularly advantageous if the triggering conditions are to be updated as required, for example in the event of changes in the law, or if different triggering conditions are to be used for different geographical areas, for example for different countries .

• 1 eine Verkehrssituation, in der ein Ausführungsbeispiel des erfindungsgemäßen Verfahrens durch ein Ausführungsbeispiel des erfindungsgemäßen Kraftfahrzeugs bzw. ein Ausführungsbeispiel eines erfindungsgemäßen Hinweis- und/oder Führungssystems ausgeführt wird, und
• 2 ein Ablaufdiagramm eines Ausführungsbeispiels des erfindungsgemäßen Verfahrens.

Further advantages and details of the invention emerge from the following exemplary embodiments and the associated drawings. Here show schematically:

• 1 a traffic situation in which an embodiment of the method according to the invention is carried out by an embodiment of the motor vehicle according to the invention or an embodiment of an information and / or guidance system according to the invention, and
• 2 a flowchart of an embodiment of the method according to the invention.

1 shows a traffic situation in which a motor vehicle 1 a traffic route 2 drives. Used by a control device 27 of the motor vehicle recognized that a driver 3 of the motor vehicle 1 the car 1 in a potential parking position 12th would like to park or stop there, is controlled by the control device 27 checked whether there are any indications that parking or stopping in the parking position 12th could be forbidden. If this is the case, a corresponding notification can be sent via a notification facility 21 , for example a display, to the driver 3 are output or the motor vehicle can be automatically guided to a position spaced apart from the potential parking position, for example an actually available parking position. A corresponding procedure could also be transferred to a fully automated operation of the motor vehicle, in which the motor vehicle 1 automatically potential parking positions 12th searches and determines whether this is necessary to park the motor vehicle 1 are suitable.

A possible implementation of such a method is described below with additional reference to the in 2 The flow chart shown is explained. The method steps explained here are not exclusively carried out by the motor vehicle 1 implemented itself, but partly also by the vehicle-external facility 15th so that the motor vehicle 1 and the off-vehicle facility 15th can be viewed together as a reference and / or guidance system. Alternatively, it would also be possible to carry out all the steps in the motor vehicle 1 to implement yourself.

As by the dashed line 18th in 2 is indicated, the method shown is divided into the prepared steps S1 until S3 which can be carried out at relatively long time intervals, for example only when the rules for assessing the permissibility of parking or stopping are to change, for example when the motor vehicle crosses a border 1 or in the event of a change in the relevant rules. The remaining steps S4 until S10 serve to support the driver 3 in driving the motor vehicle 1 in active driving mode and are during driving, for example, always or when the driver 3 has activated a corresponding assistance system.

In step S1 is via a position detection device 13th , for example a GPS sensor, a current position of the motor vehicle 1 recorded. The recorded position is used in step S2 determines in which of several geographical areas, for example in which country or federal state, the motor vehicle is located 1 is located. Depending on the geographical area, the relevant rules regarding the permissibility of parking or stopping at certain positions may vary.

In step S3 therefore becomes one of several sentences depending on the determined area 16 of rules or trigger conditions 17th , the fulfillment of which can trigger a message or an automatically leading motor vehicle to a different position, activated or loaded. In the exemplary embodiment shown, a data record 28 , of the corresponding sentence 16 of trigger conditions 17th describes from a device external to the vehicle 15th via a communication device 14th of the motor vehicle. Alternatively, all sentences could be used 15th be kept in the vehicle itself or it could only be a single sentence 16 of trigger conditions 17th can be used, which is fixed.

After a corresponding configuration by specifying the triggering conditions, the control device 27 the driving operation of the motor vehicle 1 monitors to driving situations too recognize in which the motor vehicle 1 is likely to be parked in a potential parking position. This is done in step S4 First, various relevant data is recorded and in step S5 it is checked whether these data refer to a probable or already completed parking or stop in a potential parking position 12th Clues.

As a parameter of the motor vehicle 1 can, for example, the speed via a speed sensor, not shown, a steering angle via the steering angle sensor 20th , an engaged gear of the transmission 7th and an operating state of the engine 5 or the ignition 6th be determined. Via an interior sensor 4th , for example a camera, can also be used by the driver 3 relevant sensor data are recorded. From the behavior of the driver 3 , for example from a search of the surroundings, that for example based on the direction of the driver's gaze 3 or can be recognized on the basis of upper body movements, a parking intention can be deduced. Parking maneuvers can be recognized, for example, by a change to reverse gear or a repeated change between forward and reverse gear. In addition, low speeds indicate that parking or stopping could follow. A completed parking or stopping process can be recognized, for example, when the engine is switched off or a parking gear is engaged.

If the motor vehicle 1 Should drive autonomously in an alternative exemplary embodiment, it can already be seen from the trajectory planning that the motor vehicle is to be parked or stopped.

Via environmental sensors 8th until 11 , for example cameras, the environment of the motor vehicle 1 Relevant environmental data are recorded, by evaluating potential parking positions 12th can be recognized in the current vehicle environment. Additionally or alternatively, environmental data can also be determined by taking them from a digital map as a function of the position of the motor vehicle. If there are several potential parking positions, for example, depending on the direction of view of the driver 3 or the performed driving maneuvers the most relevant potential parking position 12th can be selected for consideration in the further procedure.

Will in step S5 recognized that probably no parking or stopping in a potential parking position 12th should take place, the procedure starts at step S4 repeatedly in order to monitor the further driving operation of the motor vehicle for a desired parking. Otherwise the procedure with step S6 continued to check whether there are any indications that parking or stopping in the potential parking position 12th should be omitted in order to give the driver an indication, if this is the case, or to guide the motor vehicle at least partially automatically to another position, in particular another parking position. This is done in step S6 environmental information from the previously recorded environmental data 19th determined for judging whether parking or stopping at the parking position 12th is likely to be permissible, are relevant. At least one piece of environmental information can be the type of traffic route 2 or its geometry, a geometry of a boundary 25th of the traffic route 2 or the distance 24 the parking position 12th to another traffic route 23 affect.

In step S7 are then the trigger conditions 17th evaluated, which depend on the environmental information explained above. The individual triggering conditions can correspond to traffic rules that prohibit parking or stopping in certain areas. Additionally or alternatively, trigger conditions 17th which lead to an indication or to an automatic movement of the vehicle to another position when parking at the potential parking position 12th seems to be allowed, but would obviously lead to a significant obstruction of other road users or similar problems.

Numerous relevant trigger conditions have already been discussed in the general part of the description. In order to avoid unnecessary repetitions, only a few trigger conditions will be discussed as examples 1 shown traffic situation can be relevant. So can a respective trigger condition 17th be fulfilled if it is the traffic route 2 is a traffic route of a certain type, for example an expressway, a motorway or a forest path. At the traffic route in 1 it is, for example, a normal street within a built-up area. Thus, in the example shown, none of these trigger conditions would be met.

Is it the traffic route? 2 For example, around a street in a residential area, trigger conditions could potentially be relevant that relate to the parking of trailers or motor vehicles with trailers in residential areas. As already explained, parking is prohibited at certain times in these cases. In 1 is the motor vehicle 1 however, a car without a trailer, so that a corresponding trigger condition is not met.

Another trigger condition 17th can be fulfilled if the geometry of the boundary 25th of the traffic route 2 a lowered curb 22nd describes. This is in the in 1 example shown is the case.

Further trigger conditions 17th can, for example, check whether the parking position 12th is difficult to see or is in the area of a sharp curve. Both are in the in 1 shown example is not the case.

Another trigger condition 17th can check the distance 24 the parking position 12th from another traffic route 23 , in in 1 shown example of a confluence is sufficiently large. This is in the in 1 shown example is not the case, so this trigger condition too 17th is satisfied.

In step S8 it is checked whether at least one of the tested trigger conditions was met. As explained above, this is in the 1 embodiment shown the case, so that in step S9 a corresponding note to a user 26th of the motor vehicle 1 , especially the driver 3 , can be output, which indicates to him, for example, that parking at the potential parking position 12th probably not allowed. A corresponding notification can be made via the notification facility 21 for example, can be output as a graphic representation. Here, for example, a corresponding information symbol can be superimposed on a representation of a digital map or a video image of the vehicle surroundings. However, acoustic warning signals, voice outputs or the like are also possible.

As part of such a notice, the user can 26th other known parking options are also pointed out. For example, the device external to the vehicle 15th or another device external to the vehicle can carry out parking space management that monitors the occupancy of known parking spaces and can therefore suggest, for example, a free, permissible parking position in the vicinity as part of the notification.

As an alternative or in addition to the output of a note, it is also possible that the control device 27 directly in the driving operation of the motor vehicle 1 engages to guide the motor vehicle to a position spaced from the parking position. This can be useful, for example, for the motor vehicle 1 to automatically lead to a permissible parking position upon detection of a parking intention, especially if the motor vehicle 1 is automated anyway. At least partially automated guidance to a distant position can, however, also take place in order to move the motor vehicle out of a position in which stopping should absolutely be avoided, for example when the driver is driving the motor vehicle 1 parked in the area of a traffic route for a rail-bound means of transport.

In cases where in step S8 it is determined that none of the triggering conditions are met, the vehicle can in step S10 problem-free in the potential parking position 12th be turned off. In this case, it is not necessary to provide information or to intervene. However, provision can still be made for a confirmation message to be sent to the driver 3 output or suggest to him, for example, that the motor vehicle is automatically in the potential parking position 12th to turn off.

In the exemplary embodiment explained above, the essential steps of the method explained are carried out entirely within the motor vehicle 1 carried out. The device external to the vehicle 15th serves essentially only for a prepared configuration of the motor vehicle 1 . In modifications of the method explained, however, it would also be possible to carry out further processing steps for the processing device external to the vehicle 15th to relocate. In particular, the trigger conditions 17th or at least one of the trigger conditions 17th by the device external to the vehicle 15th be evaluated. The car 1 In the simplest case, only its position or the potential parking position can be sent to the device external to the vehicle 15th transmit, which can determine the environmental information, for example, using digital map data or with the help of a sensor system external to the vehicle.
