Description

[0001] The present invention relates to a method for controlling a parked motor vehicle. The invention also relates to a corresponding assistance system for a motor vehicle and a motor vehicle equipped therewith.

[0002] Modern motor vehicles are increasingly equipped with sensors, data processing, and communication systems, offering ever more possibilities. This opens up opportunities for new functions and applications, such as increasing user comfort, improving traffic flow, and so on. In particular, motor vehicles can automatically perform or initiate various control processes.

[0003] As an example, JP 2021 103 384 A describes a parking assistance system. This system can detect when the ignition of a vehicle parked in a parking space is switched on. The parking assistance system then transmits the vehicle's intention to leave the parking space to a specific other vehicle in the parking space. Furthermore, if the parking assistance system receives a parking intention from the other vehicle, it can transmit the position of the parked vehicle to that other vehicle.

[0004] German patent DE 10 2020 122 865 B3 describes a method for displaying camera images that depict information relating to a vehicle's surroundings. The camera images are to be displayed on an externally visible screen of the vehicle in order to assist other road users by visualizing the traffic situation in the vehicle's vicinity. For example, an approaching vehicle intending to enter a parking space can be shown the surroundings of another vehicle already parked nearby on one side of the screen, which may be obscured by the other vehicle from the approaching vehicle's perspective.

[0005] US Patent 2023 / 0121625A1 describes a parking control system for a parking facility, such as a parking lot or parking garage. The parking control system can collect user behavior information and, based on this, estimate the probability that the user will leave the parking facility with a vehicle. Based on this probability, the control system can then execute a process related to such an exit.

[0006] These approaches can also support other road users, for example, in the context of parking maneuvers. However, this does not exhaust all possibilities, and a user of a parked vehicle may not receive support.

[0007] The object of the present invention is to enable increased comfort in the context of a motor vehicle departing from its current parking location.

[0008] This problem is solved by the subject matter of the independent claims. Further possible embodiments of the invention are disclosed in the dependent claims, the description, and the figures. Features, advantages, and possible embodiments set forth in the description for one of the subject matter of the independent claims are to be regarded, at least analogously, as features, advantages, and possible embodiments of the respective subject matter of the other independent claims, as well as of any possible combination of the subject matter of the independent claims, optionally in conjunction with one or more of the dependent claims.

[0009] The method according to the invention serves to control or operate a motor vehicle parked at a parking location, particularly in the context of an impending departure from the parking space. The method can be executed automatically by or within a motor vehicle, for example, by means of a suitably configured assistance system of the motor vehicle. In one step of the method according to the invention, continuous monitoring for various predefined events is automatically performed while the motor vehicle is parked at the parking location.This allows, for example, continuous monitoring for relevant input data or signals, status changes, or switching operations, such as those from sensors, control units, or other components of the vehicle and / or a mobile electronic device (e.g., an electronic key, mobile device, etc.), and / or an external server or a user profile managed therein. Similarly, relevant input data can be recorded and analyzed, for example, from the driver assistance system. This monitoring can be carried out, for instance, using appropriate sensors, control units, or the vehicle's driver assistance system, which can be continuously or regularly active for this purpose.

[0010] In a further step, based on events detected during monitoring, a probability value is determined for the vehicle's imminent departure from its current parking location and, if applicable, the estimated remaining time until the anticipated departure. The time interval can be determined continuously or only when the probability of the imminent departure meets at least a predefined threshold. Typically, the probability value and the estimated remaining time interval can be inversely related. Thus, as the estimated remaining time interval decreases, the probability value can increase, and vice versa.

[0011] In a further step of the inventive process, depending on the current or most recently determined probability value and / or the current or most recently determined estimated remaining time until departure, one or more predefined measures are carried out in preparation for departure. For each measure, the probability value and the estimated remaining time until departure at which it is executed are specified. A specific measure, for example, a specific control or switching operation, which controls or switches at least one component of the motor vehicle, can therefore be carried out at the corresponding probability value and, if necessary, at higher probability values ​​and / or from the corresponding time interval and, if necessary, at shorter time intervals.Accordingly, if the probability value increases over time and / or the expected remaining time until departure decreases, several such measures can be carried out or started one after the other in a corresponding sequence according to the specifications.

[0012] The present invention is based on the understanding that various measures can contribute to increased comfort for a vehicle user or other road users when performed within a period ending with the vehicle's departure, and that these different measures can require varying amounts of time and / or energy. For example, air conditioning the vehicle's interior may require more time than starting up, i.e., starting the vehicle's infotainment system, or sending a readiness or information signal, for example, to the user's mobile device and / or other road users. Various input variables are considered, such as the aforementioned different input data or input signals for the specified parameters.Predefined events or data from corresponding sensors, control units, or devices can be fed to an electronic decision-maker appropriately configured for the process, which, for example, can be part of the assistance system. This decision-maker can then fuse the input variables to calculate or estimate the probability value and the remaining time. A classical algorithm, i.e., a conventional computer or calculation program, or a machine learning algorithm (ML) or a suitably trained machine learning system of the vehicle can be used. By considering the probability value and the expected remaining time until departure, as provided for in the invention, an optimal compromise can be achieved between the vehicle's operational readiness and user comfort at departure on the one hand, and energy consumption and / or fuel efficiency on the other.- especially in the case of battery-electric vehicles - remaining range on the other hand can be achieved.

[0013] In one possible embodiment of the present invention, the specified events include approaching the motor vehicle, opening a vehicle door, in particular the driver's door, occupying a seat in the motor vehicle, in particular the driver's seat, closing a seat belt buckle in the motor vehicle, in particular the driver's seat, interacting with a user interface (HMI: Human Machine Interface) of the motor vehicle, in particular entering a navigation destination, making the motor vehicle ready to drive, selecting a gear or drive mode, and moving the steering wheel. Upon recognition or detection of these events, an increasing probability value for an imminent departure and a decreasing estimated remaining time until departure are then determined in their specified sequence.The events mentioned above therefore have different probability values ​​and different temporal relationships to the impending departure, or can be assigned or classified accordingly. For example, approaching the vehicle could be the detection of a user of the vehicle or a mobile electronic device, perhaps using the vehicle's UWB sensors. Preparing the vehicle for departure could involve switching on the ignition, pressing a start button, or an equivalent action. The events proposed here, along with their suggested sequence and evaluation regarding probability and timing of departure, can enable effective and efficient preparation of the vehicle for departure.Similarly, if the vehicle is not equipped with sensors for all of the aforementioned events, other events or only some of the aforementioned events can be detected and taken into account to determine the probability value and / or the estimated time remaining until departure. This ultimately allows for a particularly high level of user convenience, as the user can then be relieved of the manual execution of predefined measures at a suitable time.

[0014] In a further possible embodiment of the present invention, the monitoring process involves checking the position of an electronic vehicle key relative to the vehicle. For example, using a UWB sensor of the vehicle (or the UWB sensor mentioned elsewhere) or similar technology, it can be monitored whether and where the vehicle key is located in the vicinity of the vehicle or within the detection range of the sensor. If it is detected that the vehicle key remains within a predetermined distance of the vehicle for more than a predefined duration, without at least one further predefined event being detected, no further predefined measures are executed, and any measures already initiated are terminated or reversed.Terminating a measure that has already started might mean, for example, stopping air conditioning, whereas reversing a measure that has already started or been carried out might mean, for example, shutting down an infotainment system that has already been started.

[0015] The proposed embodiment of the present invention can accommodate various situations in which the vehicle key is within the specified distance, for example, within the detection range of the relevant sensors, without the user planning an imminent departure. Such a situation might arise, for instance, if the user has parked the vehicle at their house and placed their vehicle key within the relevant distance or detection range in a permanent or usual storage location within their home. In such situations, the system can respond by preventing the vehicle from being unnecessarily prepared for departure, thus saving energy.

[0016] In a further possible embodiment of the present invention, the predefined measures include air conditioning the interior of the motor vehicle, starting the vehicle's infotainment system, and retrieving traffic information. Air conditioning is initiated based on a first probability value and / or a first estimated remaining time until departure. Conversely, the infotainment system is only started based on a higher second probability value and / or a shorter second estimated remaining time until departure. Air conditioning should be activated as early as possible to allow sufficient time for vehicle conditioning. Accordingly, it can react to a relatively early, but potentially still relatively uncertain, departure detection. For example, air conditioning can be started as soon as a warning light is displayed.The system detects the approach to the vehicle as described elsewhere. However, starting the infotainment system, i.e., booting it up, can only occur, for example, when departure is more likely or the expected departure time is closer. This takes into account that starting the infotainment system earlier is unnecessary, as the user would not benefit significantly and starting it doesn't take as much time as pre-conditioning or heating the interior.

[0017] However, once the infotainment system has been started and before the actual departure, it may perform various useful functions, so it should not be started at the last moment, but rather at a medium probability value or a medium expected remaining time until departure.

[0018] Traffic information can be retrieved, for example by the infotainment system, either immediately after it is started or later, before departure, i.e., within a shorter period of time. The former allows for the early detection of traffic disruptions that could significantly extend travel time. This enables users to be informed in a timely manner and adjust their travel plans accordingly. Retrieving traffic information later, on the other hand, ensures greater accuracy and thus allows for optimal route planning and arrival time calculation at the time of departure.The collection of traffic information can, for example, mean or include determining the current traffic situation and / or traffic jams and / or closures and / or detours and / or the like.

[0019] In a further possible embodiment of the present invention, one possible measure is the pre-conditioning of the vehicle's interior, for example, to a predetermined target temperature. This conditioning is carried out upon detection of at least one of the predefined events, to which this measure can be assigned, or upon a corresponding specific probability value and / or a then determined remaining time period until departure, unless the vehicle is located at the residence or workplace of a user of the vehicle. A corresponding position of the vehicle can therefore serve as a restriction criterion or blocking condition for executing the corresponding measure.The location of a vehicle at its place of residence or work can be determined, for example, using position data from a satellite-based positioning system, especially in conjunction with other data or information. This allows, for instance, the analysis of a temporal pattern in the vehicle's positions.

[0020] If, for example, it is determined that the vehicle is usually parked at a specific first location in the afternoon or evening, or overnight, and at a different second location from morning onwards, i.e., during normal working hours, the first location can be identified as the user's residence or home address, and the second location as their workplace. Similarly, the user's residence and / or workplace can be explicitly specified in the vehicle's navigation system and retrieved accordingly. The embodiment of the present invention proposed here can take into account that various predefined events can occur relatively frequently at the residence and / or workplace without the vehicle departing or being imminent.For example, the user can approach the vehicle relatively frequently, completely independently of a planned trip, or open a vehicle door to, for instance, remove or place an item inside the vehicle, or similar actions. The proposed embodiment of the present invention thus saves energy that would otherwise be required for unnecessary actions.

[0021] Similarly, the system can be configured so that the probability value and / or the estimated remaining time before a specific action is executed is predetermined, automatically selected, or adjusted based on the vehicle's current location. For example, if the vehicle is located away from the owner's home and / or workplace, the interior climate control can be activated once a certain probability value and / or remaining time has elapsed. Conversely, if the vehicle is at the owner's home or workplace, climate control can only be activated once a higher probability value and / or a shorter remaining time has elapsed. This reduces instances where climate control is activated erroneously or unnecessarily, i.e., when no departure is imminent.At the same time, however, in cases where the vehicle actually departs, greater comfort for the user can be achieved than if the air conditioning is not started automatically at all.

[0022] In a further possible embodiment of the present invention, one possible measure is the transmission of a release signal, indicating that the parking space of the motor vehicle is about to become available, to other road users in the vicinity of the parking space or the motor vehicle and / or to an external traffic management system. Such a release signal can be transmitted, for example, via a Car2X data connection or, for example, via a WLAN or mobile network connection.For example, the release signal may be sent only when there is a relatively high probability value, which may be higher than the second probability value mentioned elsewhere for starting the infotainment system, and / or when there is a relatively short remaining time until departure, which may be shorter than the second remaining time period mentioned elsewhere for starting the infotainment system. Such a release signal can make it easier for other road users to find a parking space, thus providing greater convenience for them. It can also potentially improve traffic flow and prevent unnecessary fuel or energy consumption by other road users searching for a parking space for an extended period.

[0023] In a possible further development of the present invention, the release signal, for example upon detection of at least one of the predefined events associated with this measure, or from a predefined probability value and / or from a predefined expected remaining time until departure, is only issued if the current parking location has been recognized as a permissible parking location. For example, the parking location can be recognized as a permissible parking location, and the release signal can be sent, if a parking maneuver to park the vehicle at the respective parking location has been carried out automatically or with the assistance of a parking assistance system of the vehicle. Such a parking assistance system can include a function for recognizing permissible parking locations or valid parking spaces and only offer automated execution or assistance of the parking maneuver upon such recognition.Similarly, a parking location can be recognized as a permissible parking location or valid parking space independently of, or without, the use of, a parking assistance system for the automated execution or support of the parking process, for example, by means of a corresponding recognition function or based on traffic sign recognition or the like. Likewise, a parking location can be recognized as a permissible parking location or valid parking space if it is marked accordingly in map data, i.e., recorded there, for example, as a parking space, parking lot, parking area, parking garage, or the like. The further development of the present invention proposed here can prevent other road users from being encouraged to park their vehicles in an impermissible parking location or to travel unnecessary distances.

[0024] In a possible further development of the present invention, the release signal is sent from the detection of at least one of the predetermined events, to which, for example, this measure may be assigned, or from a corresponding specific probability value and / or from a then determined expected remaining time span until departure, unless the motor vehicle is located at the residence or place of work of the user of the motor vehicle and / or unless the current parking location, for example before or when the motor vehicle was parked at the respective parking location, was recognized as an unauthorized parking location and / or unless the current parking location is located away from traffic areas specified or recorded in a map or map data.The latter can occur, for example, in unclear road situations, such as when a vehicle is parked in a construction zone, on a dirt road, in a field, or similar location. An unauthorized parking location can be identified, for instance, through traffic sign recognition, such as when a no-parking sign is detected. At the user's residence or workplace, the parking location is more likely to be a private parking space, garage, or similar structure, and therefore not intended for public use. Access restrictions may also apply. The proposed design thus prevents other road users from being directed to a parking location that they are unlikely to be able or permitted to use for their own vehicles.This can prevent other road users from being encouraged to park their vehicles illegally and / or to travel unnecessary distances.

[0025] The present invention also relates to an assistance system for a motor vehicle. The assistance system according to the invention has an input interface for acquiring event data, each indicating at least one of several predefined events, and a data processing unit for processing the event data and determining a corresponding probability value for an imminent departure of the motor vehicle from its current parking location and, optionally, an estimated remaining time until the vehicle's departure, as well as for generating control signals to execute one of several predefined actions depending on this probability value. The event data can, for example, be or include the input variables, input data, or input signals mentioned in connection with the method according to the invention.Depending on its design, the assistance system may also have an output interface for sending control signals, for example to various devices, components, control units, actuators, or the like. The input and output interfaces may be separate or combined or integrated into a common, particularly bidirectional, interface. Likewise, the input and output interfaces may each be implemented entirely or partially in hardware and / or software.

[0026] The assistance system according to the invention is designed for the automatic execution of the method according to the invention. For this purpose, the assistance system, in particular its data processing unit, can comprise, for example, a process unit such as a microprocessor, microchip, microcontroller, or the like, and a computer-readable data storage device coupled thereto. This data storage device can then contain an operating or computer program that encodes or implements the process steps, measures, or sequences described in connection with the method according to the invention, or corresponding control instructions. This operating or computer program can then be executed by means of the process unit in order to execute the corresponding method or to effect its execution.

[0027] The present invention also relates to a motor vehicle equipped with the assistance system according to the invention. Thus, the motor vehicle according to the invention is also equipped to automatically execute the method according to the invention. Accordingly, the motor vehicle according to the invention can be the motor vehicle mentioned in connection with the method according to the invention and / or in connection with the assistance system according to the invention, or it can correspond to the motor vehicle mentioned therein. The motor vehicle according to the invention can therefore have some or all of the properties and / or features mentioned in these contexts. For example, the motor vehicle – as part of the assistance system or coupled to it – can have a monitoring device or sensors for continuous monitoring for several predetermined events or for the detection of such events.Similarly, the motor vehicle may, for example, have a communication device for sending signals, such as the aforementioned release signal or an information signal for the user, or the like.

[0028] Further features of the invention may become apparent from the following description of the figures and from the drawings. The features and combinations of features mentioned above in the description, as well as the features and combinations of features shown below in the description of the figures and / or in the figures themselves, can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention.

[0029] The drawing shows a schematic representation in the single figure to illustrate the control of a parked motor vehicle for departure optimization.

[0030] Communication between vehicles, for example with each other or with a user's or driver's mobile device, as well as intelligent data analysis, can enable a variety of convenience features. This section illustrates how an impending parking maneuver—that is, a desire to pull out or the intention to drive off—can be detected and used as a trigger or reference for various automated actions. Knowing that a vehicle is about to pull out can increase convenience for the driver and / or other road users. For example, this knowledge can be used to automatically prepare the vehicle for departure and / or to inform the driver, perhaps based on an automatically performed, internet-based route query.about current or expected traffic conditions or the like, and / or to share this information with other vehicles or road users via networked functions, such as a Car2Car message. This is shown in... Fig.Figure 1 is an exemplary scheme 1, such as it might be implemented or executed by an assistance system 14 of a motor vehicle 15. Here, a sequence of several predefined events 2 is depicted. Corresponding to this sequence of events 2 are two arrows, one representing the increasing proximity T to the departure time along the sequence of events 2, and the other representing the increasing probability P to the departure time along the sequence of events 2, i.e., an increasing probability value that a departure is actually imminent. A greater proximity T to the departure time corresponds to a shorter expected remaining time until departure.

[0031] Furthermore, several measures 3 are represented here, which, depending on the proximity of the departure time T and / or the probability of departure P, can be automatically executed at different points along the sequence of events 2 by the corresponding motor vehicle 15.

[0032] For example, the assistance system 14 of the respective motor vehicle 15 can continuously monitor for input data or input signals, each of which indicates one or more of the events 2. Such events 2 can be, for example, an approach 4 to the motor vehicle 15, a driver's door opening 5, a seat occupancy 6, which can be detected, for example, by a seat occupancy sensor or by the closing of a corresponding seat belt buckle, a user interaction 7, the vehicle being ready to drive 8, a gear selection 9, and a steering wheel angle 10. It is not always necessary for all of these events 2 to be detected. The events 2 also do not necessarily have to be detected in the order mentioned.However, it can always be the case that when a specific event 2 is detected, a current departure time proximity T and a respective departure probability P are determined from this or also taking into account the other events 2 already detected in the immediately preceding period. According to a corresponding specification, one or more of the measures 3 are then carried out, if necessary.

[0033] Examples of such measures include activating air conditioning 11, starting a system 12 (e.g., powering on the vehicle's infotainment system 15), and sending a release signal 13. Air conditioning 11 is activated here even with a relatively early and uncertain detection, i.e., when the departure time is relatively close T, resulting in a correspondingly long time until the expected departure and a relatively low probability of departure P. For example, air conditioning 11 can be activated upon detection of approach 4. System startup 12 occurs when the average departure time is closer T and the average departure probability P is correspondingly higher. For example, system startup 12 can be triggered by the detection of a seat occupancy 6.The release signal transmission 13 to inform other road users about the soon-to-be-vacant parking space of the motor vehicle 15, however, only occurs when the departure time T and departure probability P are even closer, i.e., relatively close. For example, the release signal transmission 13 can be executed upon detection of a gear selection 9 or upon detection of a steering wheel movement 10.

[0034] However, one or more situations or conditions may be predefined in which a specific event 2 is detected, or a corresponding departure time proximity T and / or a corresponding departure probability P has been or would be determined, but the corresponding measure 3 is nevertheless not executed. In such situations or scenarios, the corresponding reactions of the vehicle 15 to detected events 2 may therefore be partially or completely restricted. This may, for example, involve an unwanted or inappropriate release signal 13 to other road users in the respective situation, or an unwanted continuous reaction to a detected or presumed approach 4, for example, if the vehicle 15 is parked at the user's home or workplace.

[0035] Overall, the examples described show how a method for recognizing an intention to park or depart can be implemented and applied to optimize existing parking and information functions.
