Description

[0001] The present invention relates to a rule-based interaction method for a motor vehicle with its environment and related devices.

[0002] Modern vehicles offer a range of functions that can be used by the driver, front passenger, and other occupants. These include infotainment and entertainment features such as entering navigation destinations, selecting radio stations, adjusting volume, making phone calls, choosing music tracks, and much more. This category is further enhanced by driver assistance and comfort features, such as seat adjustment, mirror adjustment, interior temperature control, garage door opener, and warning information.

[0003] To enable such functions, modern vehicles are equipped with a range of sensors and actuators. Their combination allows for a large portion of the offered functionality. However, monitoring and triggering these functions are currently predominantly manual and still very inflexible in terms of adaptability. Examples include adjusting the mirrors when entering an underground parking garage, muting the radio when approaching a hazard, adjusting the climate control, operating the light switch, sending text messages and making phone calls, or entering a destination.

[0004] Some of this functionality is automated today, such as automatic headlights, automatic mirror adjustment when parking, automatic activation of parking distance control, and the reversing camera. Unfortunately, these processes often still have to be performed manually or they operate according to a rigid and very limited automation scheme.

[0005] Therefore, it would be desirable to provide a way to make such processes more flexible.

[0006] Publication DE 10 2008 064 022 A1 discloses an arrangement and a method for providing hazard situation-dependent warning information, which at least one warning information output unit outputs to the driver of a vehicle using at least one sensory channel, wherein an evaluation and control unit receives and evaluates information from at least one sensor unit.

[0007] Publication DE 10 2006 013 971 A1 discloses that at least one feature relating to a second information system is automatically transmitted to the first information system via a communication link in order to enable a user's interaction with an application by means of interaction elements adapted to an environment in a particularly flexible manner.

[0008] Publication DE 10 2004 042 940 A1 discloses a method for managing event entries of a digital tachograph that improves user control by centrally storing events with priorities and selecting them for further processing.

[0009] Publication EP 1 415 864 A1 discloses a method which adapts vehicle functions based on vehicle characteristics, driver preferences and a driving load estimate in order to control their activation or deactivation.

[0010] Publication DE 603 ​​13 373 T2 discloses an interactive system and method for vehicle control.

[0011] The aim of the invention is to propose a possibility which avoids or at least reduces some of the disadvantages known in the prior art.

[0012] The problem is solved according to the invention by means of a method according to the main claim, as well as by means of devices according to the dependent claims.

[0013] The subject matter of the main claim relates to a rule-based interaction method for a motor vehicle with its environment, comprising: maintaining at least one event rule, wherein the event rule comprises at least one condition from a condition group and at least one action from an action group. The condition group comprises: a spatial condition, a temporal condition, a vehicle user-related condition, a vehicle-external condition, a vehicle-related condition, and a logical operator condition. The action group comprises: a vehicle-internal action and a vehicle-external action. Furthermore, the rule-based interaction method comprises: receiving an event set, wherein the event set contains at least one event. Checking, for each event rule, whether all conditions of the corresponding event rule are satisfied by the event set.And if the test shows that all conditions of the corresponding event rule are met: Execution of the corresponding action of the corresponding event rule as an interaction of the motor vehicle with its environment.

[0014] The process steps can be automated.

[0015] An event within the meaning of the invention can be part of an unfolding situation. For example, a situation might be that the motor vehicle drives in front of a garage door. The resulting event would be the time at which this occurs. Another related event would be the vehicle's position in this situation. A further event could be the engine state, i.e., whether the engine is running or switched off. Thus, a single unfolding situation can comprise various events.

[0016] Accordingly, an event set within the meaning of the invention can comprise the recorded events of a situation.

[0017] An event rule within the meaning of the invention can be the execution of one instruction or one action, or several instructions or actions, wherein the execution is subject to conditions.

[0018] An action within the meaning of the invention can refer to a process to be carried out. In particular, an action can relate to an instruction to an actuator of a device. If the event rule has more than one action to be carried out, all actions of the corresponding event rule can be executed if the corresponding conditions of the event rule are met.

[0019] A condition within the meaning of the invention can be a verifiable condition. A condition imposes a condition on an event within a situation. The condition can, for example, be formulated as a program instruction for corresponding rule-based software.

[0020] A local condition within the meaning of the invention can include a condition relating to a local position. For example, a local condition can be formulated in words as a sentence: "The local position of the motor vehicle must correspond to a local position within a certain radius of the garage." As a clear example, a pseudo-programming code could look like this: if posCar = posAroundGarage.

[0021] A temporal condition within the meaning of the invention can include a condition relating to a time. For example, a temporal condition can be formulated in words as a sentence: "The current time must be 5:00 PM or later, but before midnight." As a clear example, a pseudo-programming code could look like this: if actTime >= 17:00 and actTime < 00:00.

[0022] A vehicle user-related condition within the meaning of the invention can mean a condition that concerns a vehicle user of the motor vehicle.

[0023] For example, such a condition could relate to the vehicle user's position in front of the vehicle, resulting in a more complex event rule: "If the vehicle is within 5 meters of the garage, it is winter time, it is already after 5 p.m., and the vehicle user is between the garage and the vehicle, then the high beams must be switched on." In this example of an event rule, the rule has the five conditions of the sentence above. "Switching on the high beams" represents the corresponding action of the event rule, which is executed when all five conditions are met.

[0024] A logical operator condition within the meaning of the invention can be a logical condition such as "and", "or", "exclusive or", "not", and the like. A logical operator condition is preferably not limited to Boolean expressions. In the aforementioned example of a more complex event rule, the event rule consists of more than the five conditions mentioned above, since the conditions in the event rule are all linked to each other using logical operator AND conditions.

[0025] An external condition within the meaning of the invention can be a condition that does not relate to the motor vehicle itself, but to its environment. For example, an external condition could be a weather condition at the location of the motor vehicle, such as rain or fog.

[0026] A vehicle-related condition within the meaning of the invention can be a condition relating to the motor vehicle itself. For example, a vehicle-related condition could be a condition on a door of the motor vehicle, such as the driver's door being open.

[0027] An internal vehicle action within the meaning of the invention can be an action or instruction relating to the motor vehicle itself. For example, an internal vehicle action could be an instruction to the motor vehicle's high beams, such as switching on the high beams.

[0028] An action external to the vehicle within the meaning of the invention can be an action or instruction relating to the environment of the motor vehicle. For example, an action external to the vehicle could be an instruction to the garage door, such as "open garage door".

[0029] The invention offers the advantage of automating processes related to driving. This relieves the vehicle user and / or provides greater comfort.

[0030] The subject matter of a dependent claim relates to an interaction device for a motor vehicle, comprising: an interface for communication between the interaction device and a vehicle-integrated device. The vehicle-integrated device comprises a device from the vehicle-integrated device group. The vehicle-integrated device group comprises: a motor vehicle actuator, a motor vehicle sensor, and a motor vehicle data interface. Furthermore, the interaction device comprises another interface for communication between the interaction device and a third-party device. The interaction device is configured to execute a rule-based interaction method according to the invention.

[0058] The invention thus makes it possible to automate the execution of situations and related actions concerning automobiles or motor vehicles.

[0059] The invention will be explained in more detail below with reference to the figures. These show: Fig. 1 a schematic representation of a proposed method according to an exemplary embodiment of the invention; Fig. 2 a schematic representation of a proposed method according to a further exemplary embodiment of the invention; Fig. 3 a schematic representation of a proposed method according to a further exemplary embodiment of the invention; Fig. 4 a schematic representation of a proposed device according to a further exemplary embodiment of the invention; and Fig. 5 a schematic representation of an exemplary use of the in Fig. 4 device shown in a motor vehicle according to a further exemplary embodiment of the invention.

[0060] Fig. Figure 1 shows a schematic representation of a proposed method according to an exemplary embodiment of the invention.

[0061] This shows Fig. 1. A rule-based interaction procedure for a motor vehicle 1000 with its environment, comprising: Provision 10 of at least one event rule 100, wherein the event rule 100 comprises at least one condition 110 from a condition group and at least one action 120 from an action group. The condition group comprises: a local condition, a temporal condition, a vehicle user-related condition, a vehicle-external condition, a vehicle-related condition, and a logical operator condition. The action group comprises: a vehicle-internal action and a vehicle-external action. The rule-based interaction procedure further comprises: Receiving 20 an event set 300, wherein the event set 300 comprises at least one event 310.Check 30, for each event rule 100, whether all conditions 110 of the corresponding event rule 100 are satisfied by the event set 300, and if the check shows that all conditions 110 of the corresponding event rule 100 are satisfied: Execute 40 the corresponding action 120 of the corresponding event rule 100 as an interaction of the motor vehicle with its environment. In the example of the . Fig. 1. A large number of event rules 100 are maintained, and each of these event rules 100 has both several conditions 110 and actions 120. Furthermore, the event set 300 in the example of the Fig. 1 also a large number of events 310. In the example of the Fig. 1. For the upper event rule 100, all conditions 110 are met, so that all actions 120 present in the event rule are executed.

[0062] Fig. Figure 2 shows a schematic representation of a proposed method according to a further exemplary embodiment of the invention.

[0063] This shows Fig. 2 a schematic representation of a procedure compared to the procedure from Fig. 1. Extended procedure. The previously to Fig. 1. The above applies accordingly to Fig. 2 continued.

[0064] In Fig. 2. In the rule-based interaction procedure, event rule 100 also has a prioritization. Furthermore, the rule-based interaction procedure stipulates that if all corresponding conditions 110 are met for more than one event rule 100, the corresponding action 120 is executed for the event rule 100 with the higher priority. Fig. In addition, all conditions 110 of the lower event rule 100 are met. Furthermore, the lower event rule 100 has a higher priority.

[0065] Therefore, in contrast to the example from Fig. 1 in which the actions 120 of the upper event rule 100 are executed, in which Fig. 2. The actions 120 of the lower event rule 100 were executed.

[0066] Fig. Figure 3 shows a schematic representation of a proposed method according to a further exemplary embodiment of the invention. For the sake of clarity, the method section from the example of Figure 3 is shown. Fig. 1 or the Fig. 2 has been omitted. This is indicated by “…” before and after the described procedure. Fig. 3 shown.

[0067] This shows Fig. 3 A schematic representation of a rule-based interaction procedure, wherein the rule-based interaction procedure further comprises: Collecting 50 events 310. Identifying 60 a recurring event by means of a corresponding evaluation of the collected events 310. And learning 70 another event rule 200 by means of the identified recurring event.

[0068] Fig. Figure 4 shows a schematic representation of a proposed device according to a further exemplary embodiment of the invention.

[0069] How Fig. As can be seen from Figure 4, the interaction device 400 has: An interface 410 for communication between the interaction device 400 and a vehicle-integrated device 500. The vehicle-integrated device 500 comprises a device from the vehicle-integrated device group, and the vehicle-integrated device group comprises: A vehicle actuator, a vehicle sensor, and a vehicle data interface. Furthermore, the interaction device 400 has another interface 420 for communication between the interaction device 400 and a third-party device 600. The interaction device 400 is configured to execute an interaction method according to the invention.

[0070] The Interaction Device 400 can thus manage a set of formal rule descriptions, i.e., event rules 100. These can be stored, for example, in XML notation. Furthermore, the Interaction Device 400 is responsible for continuously evaluating the executability of these stored event rules 100. In addition, the Interaction Device 400 can be flexibly extended with additional sensors, actuators, and data interfaces via external participants such as CE devices. The interfaces for interaction with the Interaction Device 400 can be divided into four areas, for example: connection to internal sensors, actuators, and data interfaces; connection to external sensors, actuators, and data interfaces; and import and export interfaces and synchronization with the backend, USB, CE devices, and the like.An event interface for the context-based transmission of event rules 100, for example when entering a parking garage 600. These event rules 100 can only be valid for a limited time and space.

[0071] The interaction device 400 can have multiple interfaces for importing and exporting event rules 100. This allows event rules 100 to be created and / or stored on a backend server in the network and transmitted wirelessly to the vehicle. Furthermore, continuous synchronization of the corresponding event rules 100 between the vehicle and the backend is possible, thus creating local transparency regarding rule processing.

[0072] The processing and / or creation of event rules 100 can also be carried out at other locations, such as in the vehicle, a desktop application, on a CE device, and the like. Transfer to and from the vehicle can be done, for example, via USB (i.e., using a data carrier) or via UMTS, WLAN, NFC, Bluetooth, and the like (i.e., via wireless transmission).

[0073] The event rules themselves are therefore not rigid, but flexible and highly dynamic. They can be independently adapted to specific needs. This adaptation can be achieved in particular through user-created event rules.

[0074] Created event rules (100) can therefore be easily shared between different participants, for example via a website or a social network.

[0075] Standard rule import can be performed context-independently and by the user. However, so-called push rules can also be used as event rules 100. These can be applied within a specific context. These push rules can also typically be limited in time and location. For example, event rules 100 can be applied when a hazardous situation is approaching and warnings need to be displayed in the vehicle. For instance, if an emergency vehicle is approaching the vehicle 1000, such a push rule can be applied to the interaction device 400 of the vehicle 1000 to automatically mute the radio and display a corresponding warning message on the vehicle 1000's screen.Furthermore, event rules 100 could also be transferred to the motor vehicle 1000 in the case of spatial approaches such as to a parking garage, shop, petrol station, garage and the like.

[0076] Event rules stored in the vehicle can be categorized as global or personalized. Global event rules can be executed by all vehicle users. Personalized rules, however, can be assigned to a specific vehicle user or user group and are only executed if that person has previously identified and possibly authenticated themselves at the vehicle, for example, using their key.

[0077] If multiple event rules (100) exist in the system that could lead to conflicts, the individual event rules (100) can be processed in a prioritized manner. In this case, only the event rule (100) with the highest priority can be executed, or its actions (120) can be carried out. However, it is also possible for all event rules (100) whose conditions (110) are fully met to be executed in order of their prioritization. For example, the prioritization of event rules (100) can also be based on the current vehicle state and / or location. Examples of this could be whether the vehicle is moving, whether the vehicle is in a city, whether the vehicle is in a rural area, and so on. Depending on these states, an event rule (100) can thus also be prioritized.

[0078] The interaction device 400 can also be protected with appropriate current security mechanisms with regard to the input of event rules 100, for example in the areas of verification, authentication and authorization.

[0079] Current and recurring processes can be collected within the vehicle context. This allows the vehicle to automatically generate suggestions for event rules (100) and offer them to the user. Machine learning methods can be used for this purpose. Such an event rule (100) can be learned from a set of events (310) occurring at a given time and recognized actions (120) being executed at that time, especially if these events (310) and actions (120) are recurring.

[0080] Fig. Figure 5 shows a schematic representation of an exemplary use of the in Fig. 4 device shown in a motor vehicle according to a further exemplary embodiment of the invention.

[0081] This shows Fig. 5 a motor vehicle 1000, which has an interaction device 400 according to the invention (in Fig. 5 not shown). The motor vehicle 1000 is capable of interacting with a variety of external devices 600. In the Fig. Figure 5 shows some examples of such non-vehicle devices 600, such as a traffic light 600, a parking garage 600, a smartphone 600, a web application 600, and an emergency vehicle 600. The motor vehicle 1000 is able to interact with the non-vehicle devices 600 by means of the interaction device 400, i.e., for example, to perform corresponding actions 120 (in Fig. 5 not shown) of a corresponding event rule 100 (in Fig. 5 not shown) to execute 40, events 310 (in Fig.(5 not shown) to collect 50 and event rules 100 to read in 80.

[0082] The following are some application examples according to the invention for corresponding event rules 100 in fully formulated language: “If GPS position within a radius of 100m of (49.22, 15.12) and the engine is switched off, then send an SMS to +49 171 4433221 with the information ‘Hello, I will be at your house in about 5 minutes!’”

[0083] "If GPS position is within a 2m radius of (50.22, 15.12), open the garage."

[0084] "If the engine is switched on between 08:00 and 09:00 Monday to Friday, then send a text message with the text 'Drive now!' to +49 160 44332211"

[0085] "If the outside temperature is less than 4 degrees Celsius, switch the seat heating to level 2 and the air conditioning to 23 degrees!"

[0086] "When entering the parking garage, display the message 'Please drive to parking space 345 on level 3' and configure the navigation system to parking space 345 on level 3, and turn on the headlights."

[0087] In the last example, a device in parking garage 600 sends an event rule 100 to the vehicle 1000, telling the vehicle user which parking space to drive to in the parking garage. Additionally, an action 120 is instructed to a lighting device 500 (not shown in the figure) to switch on the headlights.

[0088] The invention can be summarized as follows. A method and related devices are provided, enabling a central control and process device or method. This device connects to a large proportion of the sensors, actuators, and data interfaces installed in the vehicle, allowing for flexible configuration of functional sequences. This enables a high degree of flexibility for automating everyday processes within the vehicle. Furthermore, it provides numerous possibilities for implementing individual and personalized adjustments to vehicle functions. The invention also allows for the dynamic integration of event rules via a push approach, enabling context-based adjustments, such as event rules in parking garages, on highways, in cities, in front of shops, in front of garages, and the like.This allows for a very high degree of individualization in the vehicle. Additionally, the system is easily expandable to include further processes, and the invention opens up the possibility of making adjustments at various points, for example, on the web, via a CE device, in the vehicle itself, and so on. Created event rules can also be easily exchanged between different participants, for example, via a website or a social network. Furthermore, the invention also allows emergency vehicles such as police cars, fire trucks, ambulances, and similar vehicles in operation to transmit event rules 100 to the corresponding vehicle 1000 using a push procedure, in order to react appropriately to emergency situations, for example, by muting the radio 500 of the vehicle 1000 until they have passed it.
