Description

The invention relates to a control device and a method for controlling at least one vehicle component of a motor vehicle, wherein each vehicle component provides a vehicle function whose functional scope can be set and / or limited via a function parameter.

Restricting a functional range of a motor vehicle is for example from the US 2015/0025705 A1 known. Thereafter, the range of functions of the motor vehicle is determined, in which the identity of a driver is determined and to the identity of a profile data store profile data are read, which contain the settings desired by the driver for the motor vehicle. If an unknown person drives the motor vehicle, a so-called valet mode is activated, which restricts the functional range of the motor vehicle.

A disadvantage of this motor vehicle is that only for the driver settings can be saved and activated. Furthermore, it is disadvantageous that for each person who is to be newly registered in the motor vehicle, each of their settings must be made completely again.

From the DE 103 50 715 A1 For example, a method for setting user-dependent parameter values in a motor vehicle is known. The parameter values can be stored in the motor vehicle or else in a vehicle-external data memory.

From the DE 10 2006 058 103 A1 a man-machine interface for a motor vehicle is known which can be adapted to persons. An operator is in this case determined depending on entered person-specific data in a question-answer dialog and depending on received person-specific data then a configuration is determined.

Although this simplifies entering parameter values for configuring vehicle components, an individual configuration must be provided for each person.

The invention has for its object to determine in motor vehicles with little effort for a person, to what extent they may use the vehicle.

The object is solved by the subject matters of the independent claims. Advantageous developments of the invention are disclosed by the features of the dependent claims, the following description and the figure.

The invention provides a method for controlling at least one vehicle component of a motor vehicle. Each vehicle component provides a vehicle function whose functional scope can be set and / or limited via a function parameter. Such a range of functions may include, for example, the permitted engine power, the media contents reproduced by a media player, the displays on an instrument cluster, the scope of operation in an informational entertainment system, and / or the lighting operation. In this case, it is possible by means of a control device to determine the functional scope of each vehicle component for a person, without the function parameters having to be determined individually for each person. For this purpose, a plurality of roller data sets are provided by the control device, wherein each roller data record describes a roll that can be taken in the motor vehicle and contains a parameter setting for the respective functional parameter of the at least one vehicle component, regardless of who holds the described roller.

Such a role may be, for example, that of the owner, a passenger, a chauffeur, a friend, a family member, a child and / or a vehicle renter. For each or each of these exemplified roles, one roll data set may be provided each. The control device detects at least one person using the motor vehicle a person identifier, that is, for example, a user number uniquely assigned to the person. On the basis of the detected person identifier, a profile data record of the person is determined in a profile data memory. The profile record indicates a role exercised by the person using the motor vehicle. If, for example, the owner of the motor vehicle uses his own motor vehicle, the role "owner" is determined on the basis of the person identifier from the profile data record. For the determined role, the associated role data set is selected, as provided by the control device. Thus, a respective parameter setting for the respective function parameter of the at least one vehicle component is present in the scroll data record. In the case of the at least one vehicle component, the respective functional scope is then set on the basis of the parameter setting contained in the selected scroll data set. For example, a parameter setting for the owner role may mean that the engine power is provided indefinitely, while the parameter setting for the guest role may limit the engine power to a fraction of the maximum possible engine power.

The parameter setting can generally determine the switching on or off of a vehicle function and / or the permitting or prohibiting a vehicle function and / or limiting the vehicle function. Thus, based on the role of the roller data set to be unlocked range of functions of the corresponding vehicle function is set in the motor vehicle.

The invention provides the advantage that, regardless of the personal preferences of a person, the functional scope of the vehicle components of the motor vehicle is determined solely by the relation of the person to the motor vehicle or generally what role the person takes when using the motor vehicle.

It is preferably provided that the roller data sets are editable and a user input of a user is received by an operating device, by means of which an existing scroll data set is changed and / or a new scroll data record is generated. In other words, the user can thus set roles themselves and / or define the functional scope for a role by specifying a corresponding parameter setting. For example, an owner of a motor vehicle may provide roles for his family members. The roles here need not be limited to driving the motor vehicle. For example, a person can also be assigned a role for persons in a back seat, for example, whether it is a minor passenger or a full-age passenger. Accordingly, a media content can then be specified for a rear-seat media playback.

An unknown person, whose personal identification no profile data record can be determined, is preferably assigned a predetermined standard role. This has the advantage that a range of functions is defined for each person, even if this person has not yet been explicitly assigned a role. In this way, it can be prevented, for example, that when the motor vehicle is in use by a foreign person, the full range of functions of the vehicle components is available. Furthermore, the motor vehicle can be lent, for example, or provided to a valet and it can be ensured that it has only a functional scope according to the standard role in the motor vehicle.

In order to assign a person a role, it is preferably provided that a management input of a user is received by a management device. In other words, a user enters the management input into the manager. In a respective profile data set of at least one person, one role per motor vehicle is determined depending on the administrative input. The user can thus assign a vehicle-specific role to a person for a motor vehicle or several motor vehicles. Thus, a person may be the owner of a motor vehicle and take the appropriate role, while the same person receives in another motor vehicle, for example, only the role "guest".

In addition to or as an alternative to manual role specification, a person's role can be automatically recognized by an analysis device and entered into their profile data record. The automatic role recognition can take place via a face recognition and / or via further sensor data of the vehicle sensor system. This can, for. B. identify smart devices (smartphones, tablet PCs) of persons and / or determine the weight and / or size of a person. A degree of kinship can be deduced based on matches in facial features. Children can be identified based on size / weight / age estimate and the vehicle conditioned accordingly.

In addition, z. B. in a driver on the driver's seat and a child on the consideration and missing other passengers are inferred that it is the driver to a supervisor (mother or educator) of the child. Through relationships between people in a vehicle (eg, a vehicle owner and a friend), it is also possible to automatically deduce the role in another vehicle (eg, in the friend's vehicle where the roles are just swapped). If the owner is sitting in the rear right and only the space on the steering wheel is still occupied, can be closed to the driver on a chauffeur. A role can also be identified by linking people to social networks on the Internet (eg Facebook ^TM ). Here the relationships are partially integrated or explicitly stated. Said analysis device may be at least partially provided as a computing device in the motor vehicle and / or at least partially as a server of the Internet.

The roller concept described thus has the particular advantage that when several people in the vehicle conflict between different parameter settings can be solved. For a plurality of persons using the motor vehicle, one roller is thus preferably determined in each case, and from different parameter settings taken from the roller data sets of the determined rollers, which result for the same functional parameter, then an overall setting becomes dependent on a predetermined one Roles hierarchy of roles formed. For example, it may be provided that in a chauffeur vehicle the driver has the role of "driver" and a passenger on a back seat has the role of "boss". As an overall setting, it is then possible, for example, to dominate the parameter setting of the person in the backseat, for example when setting an air-conditioning temperature in the motor vehicle. The described role hierarchy may, for example, be provided in the form of a table in which a possible parameter setting or an equation or formula for calculating the resulting overall setting may be provided for the possible combinations of the roles. It can, for. For example, the calculation of an average value of the parameter settings or the selection of only one of the parameter settings may be provided.

In order to reliably determine the person identifications of persons described, it is preferably provided that a person identification is determined by a biometric recognition device, in particular a face recognizer and / or a fingerprint scanner, on the basis of person-specific features, thus for example image data of the face or the fingerprint. In addition, however, it is preferably provided that a plausibility check of a recognition result of the recognition device is carried out on the basis of person-group-specific features, thus, for example, a recognized gender, a recognized skin color, an ethnic group, an age group, weight class and / or size class. By the age group and / or weight class and / or size class can be specified in each case, in which age interval or weight interval or size interval, the body of the person is. If, for example, the person identification of a child is determined by the biometric recognition device, but it is determined on the basis of the weight class that this person has the body weight of an adult, then the recognition result is implausible. In the same way, for example, a person identification of a female person can be rejected as implausible if a gender identification signal, for example, the recognition of a face bart in a camera image, a male person. Thus, while the biometric recognition device performs a 1-out-of-N recognition, which must lead exactly to a person identification, a person-group-specific feature recognition can be carried out for plausibility, which is more robust, since a smaller number of recognition classes is required, for example, in the gender recognition only two (male or female). Accordingly, the age classes, the weight classes and / or the size classes can each be defined by intervals for which a robust recognition results, which comprises fewer recognition classes than the biometric recognition device for determining a person identity. As fallback solution can be provided that in case of unsuccessful recognition of persons by the biometric recognition device instead of the manual input or the linguistic input of the person identification takes place, for example, a PIN input.

Another possibility for determining the personal identification is given by a predetermined radio signal of a portable mobile terminal is determined by a radio device and / or in the motor vehicle in a radio signal, wherein the radio identifier is assigned to the person identifier. For example, the radio device can detect a Bluetooth signal or a WLAN signal as a radio signal and detect therein the radio code, for example a smartphone MAC.

In order to determine a person identifier by means of the described biometric recognition device or also by means of the radio device, it can be provided in a manner known per se that actual feature data are detected, for example image data of a face or a fingerprint or the radio code in the radio signal, and these with Target feature data to be compared. If a match then results in the sense of a predetermined match criterion, the person identifier assigned to the target feature data is output as a recognition result. Preferably, it is provided that the target feature data is generated by means of a one-way function, in particular a hash function, irreversible from features that have been detected on the person in the past, ie z. B. when registering the person. For example, therefore, image data and / or biometric description data, as can be detected on the person, are not stored directly, unencrypted, but are first converted by means of the one-way function into the desired feature data, which can be provided in the control device. The actual feature data, which are detected by the biometric recognition device or the radio device, are also generated by means of the one-way function of features detected on the person, so for example image data of the face and / or the fingerprint or biometric description data and / or a radio identifier , The comparison of the actual feature data with the desired feature data is thus carried out on the basis of non-reversible imaged characteristics of the person. This results in the advantage that based on the target feature data and the actual feature data can not be deduced the identity of the person, if someone seizes this feature data. This provides protection for the privacy of individuals.

In order to be able to carry out the inventive method of the role concept across several motor vehicles, it is preferably provided that profile data sets are provided in a stationary server device, for example a server of the Internet, in each of which a vehicle-specific role is specified for different motor vehicles, and to a Person identification and a vehicle identifier, the role of the person in the motor vehicle is determined. The person identification here indicates the person and the vehicle identification the motor vehicle. For example, a chauffeur may run a company car during his term of service in the role of "chauffeur", while at the end of his service he can drive in the role of "owner" with his private vehicle.

In order to carry out the method according to the invention, the invention provides a control device for controlling at least one vehicle component of at least one motor vehicle. The control device has a reel data storage for storing a plurality of reel records as already described. Furthermore, a detection device is provided for detecting a person identification of at least one person using the motor vehicle. The detection device can thus comprise, for example, a biometric recognition device and / or the described radio device and, for example, perform a comparison of actual feature data and desired feature data by means of the described one-way function. The desired feature data are each assigned to a predetermined person identifier. Furthermore, an interrogation device is provided for querying a profile data set of each recognized person in a profile data memory on the basis of the detected person identifier. Each profile data set is designed in the manner described, d. H. he contains to the person a role for the motor vehicle. An adjusting device is used to set the respective functional scope of the at least one vehicle component on the basis of the parameter setting contained in the selected rolling data set. The described devices can, for. B. each be provided by a program module of a processor device of the control device.

The control device can be provided, for example, in a motor vehicle and designed, for example, as a control device. The control device can also be realized for example by a server device of the Internet. The control device can also be designed as a distributed device, which is realized in part by the described server device and partly by a respective vehicle-side part of at least one motor vehicle.

The control device preferably has the described operator control device for editing the scroll data records and / or for creating new scroll data records. Furthermore, the management device preferably also provides the administration device by means of which a respective role of the person to whom the person record belongs can be entered or stored in personal data sets for individual different motor vehicles. The operating device and the management device can each z. B. at least one operating element and a program module include. You can also by common components, such. As a touch screen, be realized.

The invention also includes developments of the control device according to the invention, which have features as they have already been described in connection with the developments of the method according to the invention. For this reason, the corresponding developments of the control device according to the invention are not described again here.

In the following an embodiment of the invention is described. For this purpose, the single FIGURE (FIG.) Shows a schematic representation of an embodiment of the control device according to the invention.

The exemplary embodiment explained below is a preferred embodiment of the invention. In the exemplary embodiment, the described components of the embodiment each represent individual features of the invention that are to be considered independently of one another, which also each independently further develop the invention and thus also individually or in a different combination than the one shown as part of the invention. Furthermore, the described embodiment can also be supplemented by further features of the invention already described.

The figure shows a motor vehicle 10 and a server device 11 , From the motor vehicle 10 are a control unit 12 , a communication device 13 , a detection device 14 and two vehicle components 15 shown. In the vehicle components 15 For example, each may be a media player, an infotainment system, a drive motor, a rear seat media player, and / or an air conditioning device. General is by any vehicle component 15 in each case at least one vehicle function F1, F2 provided. Each vehicle function F1, F2 is configurable, so that a respective range of functions of the vehicle functions F1, F2 can be restricted and / or changed or set. It can be a respective parameter setting 16 for setting the functional scope of the respective vehicle functions F1, F2 in the respective vehicle component 15 be set.

The parameter setting 16 can through the control unit 12 be set. The control unit 12 in this case together with the detection device 14 a vehicle-side device part 17 a control device 18 which also includes the server device 11 may include. The server device 11 and the vehicle-mounted device part 17 the control device 18 can over the communication device 13 coupled, which may be, for example, a mobile radio module or a WLAN wireless local area network (WLAN) module. Through the communication device 13 can be a radio connection 19 be provided via which a communication link 20 z. B. via a mobile network 21 and the internet 22 between the controller 12 and the server device 11 can be provided.

To set or provide the parameter settings 16 is through the control device 18 the following procedure is performed.

At least one of the motor vehicle 10 each person (not shown) will each feature 23 by the detection device 14 detected. The characteristics 23 For example, it may be image data of a person's face and / or fingerprint, or a radio identifier of a mobile device carrying the person. Such a mobile terminal may be a smart phone or a tablet PC until manner. Based on the characteristics 23 it is determined who the person is and what role they use the motor vehicle 10 occupies.

In the illustrated example, the individual possible roles R1, R2, R3 are role records 24 in the control unit 12 saved. The role records 24 can also be in the server device 11 be saved. Depending on which role R1, R2, R3 the person in the motor vehicle 10 has a corresponding parameter setting 16 selected. For this purpose, each roll data set 24 a roll indication 25 and a parameter setting 16 ' which, for example, can provide a parameter value V1, V2, V3 respectively provided for the role R1, R2, R3. The parameter values V1, V2, V3 represent a respective resulting range of functions. For example, a parameter setting 16 ' indicate that certain e-mails may not be displayed in an e-mail program or that certain address data may be displayed or may not be displayed. The other example settings already described can also be specified here.

To determine the role information 25 for the person can from their characteristics 23 Is feature data 26 be generated. This can be the characteristics 23 for example by means of a one-way function 27 For example, a hash function HASH encrypted or one-way coded. The actual feature data 26 can over the communication connection 20 to the server device 11 which are a recognition device 28 may have, in which for identifying persons per person desired feature data 29 may be provided, which also with the one-way function corresponding to the one-way function 27 can be formed from features of each person to be recognized.

By the recognition device 28 can based on the actual feature data 26 and the desired feature data 29 a personal identification 30 can be determined, which can specify a unique ID of the person. It can be z. B. may be a user number.

The server device 11 can be a profile data store 31 in which for each person in each case a profile data record 32 can be stored. Each profile record 32 can become a person identifier 30 one roll each 25 ' be included. The role specification 25 ' can in the profile record 32 also vehicle-specific, including an additional vehicle identifier 33 ' with every roll specification 25 can be linked. Accordingly, when transmitting the actual feature data 26 also be provided that of the motor vehicle 10 from a vehicle identifier 33 over the communication connection 20 to the server device 11 is transmitted.

The server device 11 determined thus for the motor vehicle 10 based on the personal identification 30 the role specification 25 ' that then via the communication link 20 back to the motor vehicle 10 can be transmitted. In the motor vehicle 10 you can on the basis of the received role information 25 ' and the role records 24 the parameter setting to use 16 for each vehicle function F1, F2 are determined. If the scroll records 24 also in the server device 11 can be stored by the server device 11 the respective parameter setting 16 determined and to the motor vehicle 10 be transmitted.

The control unit 12 can then determine the determined parameter setting 16 in every vehicle component 15 to adjust.

In the manner described, a roll indication can also be provided for several persons 25 be determined. It may happen that the roles of the persons in the motor vehicle are so different that conflicting or deviating parameter settings 16 for one and the same vehicle function F1, F2 result. To a total attitude 35 For such a vehicle function F1, F2 can determine a role hierarchy 36 be defined by which, depending on the current use situation of the motor vehicle 10 present role combination in each case the overall setting 35 can be predetermined or defined.

Thus, overall, by the control device 18 provided a respective role concept for one or more vehicles. This can be prevented, then unknown persons z. B. can see the last calls of the owner. It can be the vehicle optimally adjusted to the most important person in the vehicle, for. B. the boss in the rear in the back seat.

The control device 18 allows the introduction of a role concept, which is divided into different groups of people. These can be z. B. be determined by the owner of a vehicle itself via an operating device. Additionally or alternatively, a preconfiguration z. B. the role records 24 for the roles guest, chauffeur, friend, family, owner and / or child. These can be assigned to corresponding vehicle functions F1, F2 and these enable / disable, allow / prohibit and / or limit.

The applicable for a vehicle roles R1, R2, R3 can be centrally on a server device 11 managed and transferred to other vehicles. This can have its own role for each vehicle, which is either set manually or automatically detected.

The manual determination can be made by the owner (or another authorized person) in the vehicle by means of a management device 37 take place (eg by means of an infotainment system or another operating unit) or via a mobile terminal, such as a smartphone, or on a PC.

The characteristics 23 to persons identification such. B. Face recognition or smartphone MAC address are stored coded and transmitted. This can be done by means of a one-way function 27 , such as A hash function HASH so as not to allow inference and to store the data as securely as possible. In addition, the communication can be encrypted.

Also in the vehicle can have a certain number of features and profile records 32 be stored to perform an offline detection. If an inbound person does not match any of those stored in the vehicle, a connection to the server device may be established 11 and here after the corresponding profile record 32 wanted and used this.

The vehicle can thus adapt overall to its interior situation. For example, the phone list can be hidden as soon as unknown persons get into the vehicle. If children are detected, z. For example, a child-friendly rear seat media playback can be done automatically or the child safety device can be activated automatically.

The vehicle can automatically adapt to the recognized persons and roles and thus offer maximum comfort and safety. This is preferably done automatically when using multiple vehicles.

By the control device 18 a profile system is established in the entire vehicle, which is coupled to vehicle functions F1, F2. Occupied seats are preferably recognized automatically and a profile recognition for determining a person profile 32 carried out. This can be done via a manual selection including PIN entry. Then the vehicle is adapted accordingly. The coupled vehicle functions may correspond to all vehicle areas, eg. For example, allowable engine power, contents of the infotainment system, the configuration of the instrument cluster, the rear seat media playback, the light adaptations.

Furthermore, the identification can be done by means of face recognition via a camera. On the size or the weight can be additionally closed by a seat sensor or a ToF camera (ToF - Time of Flight). Devices or smart devices can be detected via Bluetooth or WLAN.

The role recognition takes place via an evaluation of the individual characteristics 23 in combination with information about occupancy and / or other inmates and their roles and / or roles in other vehicles or information from social networks.

In the case of automatic recognition, a confidence value is preferably used to indicate the security of the recognition. If it is less than a predetermined first threshold (eg, 99.9%), the input of a PIN may be used to select a profile and authorize the person.

Below a second threshold (less than the first threshold), the profile selection manually and then confirmed with PIN.

Furthermore, on the server 11 to every profile record 32 an ID is created. For this purpose, a role for each vehicle (identified by its vehicle identifier VIN) is stored. This profile can be transmitted to terminals (eg smartphone or tablet PC) and the vehicle via a mobile radio connection and / or an Internet connection.

For each vehicle (VIN) there are several Authorized IDs that are allowed to change roles. These changes can be made by the terminals or by the vehicle. Subsequently, a new combination (ID, role) is stored for the particular vehicle.

In addition, a set of features is stored for each ID to identify the corresponding person. This gives the target feature data 29 , These features are preferred by disposable function 27 (eg hash - MD6).

The communication between the devices should be secured and authorized with certificates.

The automatic identification and role recognition can take place via a face recognition on all squares and / or via a fusion with further sensor data of the vehicle sensor system. This can detect smart devices and / or estimate weight and / or size. Additional gender, race, and / or age estimation via facial recognition can improve a person's identification and automatically select a profile. As a result, rollers for persons in the vehicle can be automatically determined.

For new people can be closed automatically to guests. This allows a valet scenario to be detected automatically. Children can be identified based on size / weight / age estimate and the vehicle conditioned accordingly.

By relationship between persons in a vehicle (eg owner - friend) can be automatically closed to the role in another vehicle. If the owner sits in the rear right and only the space on the steering wheel is still occupied, can be closed to a chauffeur. Roles can also be identified by linking social networks. Here the relations are partially already integrated. This information can be in the role hierarchy 36 be provided.

Overall, the example shows how the invention can provide a roll concept in vehicles.
