Description

Key device for capturing biometric information of a person

The present invention relates to a key device for detecting biometric information of a person with a key, which is designed to initiate a function of a motor vehicle. In addition, the present invention relates to a method for acquiring biometric information using a key for a motor vehicle, which has a sensor system.

A motor vehicle is often used not by just one person, but by several people. For example, in a family there can be several

Family members share a car. In particular, with car sharing offers it often happens that a motor vehicle is used by several people. There is often a desire for the motor vehicle to be individually adjusted to the respective user of the motor vehicle.

The published patent application DE 10 2016 008 388 A1 relates to a method for determining a distance between a mobile terminal and a vehicle. The distance is determined at two different times. The power received by a receiver and / or field strength of a signal sent by a transmitter is taken into account in a period between the two times. A distance traveled by the mobile device is determined by means of movement and

Acceleration sensors of the mobile device are taken into account.

The published patent application DE 10 2017 007 850 A1 describes a keyless one

Access system. The keyless entry system has a stationary unit which, in the active state, continuously searches cyclically for nearby mobile identification transmitters. The keyless entry system is characterized by the fact that the constant cyclical search for the mobile identification transmitter can be activated and deactivated by means of a controller in the stationary unit. This Control can be coupled with a changeable time profile. It can thus be determined when an active search is made for the identification transmitter or not.

The publication WO 2013/090282 A1 discloses a mobile device in a vehicle, the mobile device having a user interface and a wireless interface. A docking station is disclosed which can couple to the mobile device using a wired connection. A controller can couple the docking station to a vehicle start system. The vehicle may have suitable hardware or software to verify whether the mobile device is connected to the vehicle.

The published patent application DE 100 42 055 A1 discloses a personalization device for the user-dependent setting of parameter values. The motor vehicle has at least one control unit, with the personalization device

Has detection element. A biometric feature of the user can be detected by means of the recognition element and a corresponding user-related code can be transmitted to a comparison unit. The user-related code can be compared with the code stored in the comparison unit. If the code matches, assigned parameter values of the at least one control unit of the motor vehicle can be set.

In order to be able to adjust a motor vehicle individually to a person, it is necessary to collect information from the person concerned so that they can

is identifiable. However, the cited documents do not provide for data, in particular biometric data, to be recorded in this regard.

The object of the present invention is to provide a key device which can capture biometric information of a person. In principle, this would enable the person to be identified.

This object is achieved in accordance with the independent claims of this application. Useful configurations and developments of this invention are described in the subclaims.

The invention provides a key device for capturing a biometric

Information to a person. The key device has a key that is designed to initiate a function of a motor vehicle. The key is designed in particular as a physical or physical key. The key is therefore of an objective nature that can be carried by the person. The key preferably has dimensions similar to conventional vehicle keys. The key can have a key bit to mechanically open a vehicle door of the motor vehicle or to start the motor vehicle. In this case, the term key does not mean digital information, but a physical object.

The key device is characterized in that the key

Has sensor system, which is designed to capture biometric information of the person. The sensor system can have several different sensors. At least one sensor can be installed in the key. The key preferably has several different sensors. These several different sensors are preferably installed in the key and thus integrated in it. The biometric information recorded by the sensor system relates to the person. This information can be stored by the sensor system in order to evaluate it in a later step. An identity of the person is preferably determined.

The sensor system has an acceleration sensor and / or a camera in order to record the biometric information. A further embodiment provides that the sensor system has a fingerprint sensor and / or a microphone in order to capture the biometric information. An image of the person can be captured using the camera. A head or face of the person is preferably captured or photographed. A surface provided on the key can be provided as a fingerprint sensor. With the aid of this fingerprint sensor, an image of the fingerprint of a finger of the person can be captured. For example, a person's gait profile can be detected by means of the acceleration sensor. With the help of the acceleration sensor, a way in which a person moves can be detected or measured. A voice of the person can be recorded using the microphone. All of this information represents biometric

Information that can be captured by the sensor system. This biometric information can help to clearly identify the person. Since the sensor system can have different sensors, the biometric

Capturing information can ensure that enough biometric information about the person is available.

A further embodiment of this invention provides a key device, the key having a control unit which is designed based on identify an identity of the person using the biometric information. So can

for example, using an image captured by the camera, the person can be identified using facial recognition. A captured fingerprint can, for example, be compared with a previously stored and thus predetermined fingerprint in order to determine whether the person matches a given person. The acceleration sensor can detect a person's gait profile, which the

Control unit can evaluate accordingly. A gait profile can, for example

Acceleration or deceleration values at certain times include. These times can also be linked to location information. For example, a location within a building can be considered as location information. It is thus possible for the acceleration sensor to link acceleration values locally. Thus, acceleration values from a first interval can be assigned within a building and acceleration values from a second interval can be assigned outside the building. Under certain circumstances, a certain person can be inferred from the acceleration values. This is the case when a person has certain characteristic acceleration values. If, for example, there is a single person among a group of people who is, for example, active in sports, increased acceleration values can indicate that this person is jogging. This information alone can be sufficient to identify the person. The control unit can also link the different biometric information about the person and determine the identity of the person.

A further embodiment of this invention provides that the control unit is designed to determine its identity by means of an image of the person captured by the camera, by means of a fingerprint of the person, by means of a gait profile captured by the acceleration sensor or by analyzing a voice of the person , One of these sensors is preferably sufficient to determine the identity of the person. The camera can be designed as an optical sensor. It is used in particular to capture an image of the person. this happens

for example by photographing the person's head or face. If the person carries the key without holding it in his hand, the acceleration sensor can record the person's gait profile in order to identify them. The person can thus be identified even if they carry the key in their pocket, for example. The control unit of the key can provide voice control. If the person speaks in the key, the person's voice can be recorded and recorded using the microphone. The so captured Voice can be subjected to a sound analysis or a frequency analysis. The result of this tone analysis or frequency analysis can be compared with predetermined reference data. The identity of the person can be determined from this. The control unit can preferably access a previously stored voice profile of the person. This voice profile is ideally stored on an internal memory of the key.

The voice control function can be activated or deactivated, for example, by pronouncing a certain key word or a predetermined key phrase. Because the sensor system can contain several different sensors, the control unit is able to determine the identity of the person in different ways. Thus a

Identification of the person can be ensured under different situations.

In particular, the person can also be identified using the key if this person carries the key in his pocket. In this case, the acceleration sensor is preferably used, which can detect the person's gait profile. The control unit can evaluate this gait profile and infer the identity of the person.

Another embodiment of this invention provides a key device, the control unit being designed to provide the function of the motor vehicle as a function of the identity of the person. The function can include, for example, activating or deactivating the motor vehicle. However, the function can also mean complex adjustment of the motor vehicle. For example, a specific component of the motor vehicle can be preheated in order to gently activate the motor vehicle. For example, if the person wishes to use the motor vehicle in a cold environment, for example during the winter, the control unit can initiate a gentle activation of the motor vehicle in advance using the key. In this case, it could be provided, for example, that a battery of the motor vehicle is preheated so that the motor vehicle can be activated more gently.

It is also possible that, depending on the identity of the person, only certain predetermined functions of the motor vehicle are provided. For example, it makes sense if underage children can only open a trunk of the motor vehicle. So these underage children can open the trunk or the vehicle compartment of the motor vehicle, for example to forget forgotten ones Getting objects out, and yet ensuring that a

improper use of the motor vehicle is prevented.

For example, is a person misconduct when maneuvering the

Known motor vehicle, so this person can be separately and as clearly as possible pointed out their weakness. If, for example, it is known that a family member of a family frequently misjudges the dimensions of the motor vehicle, it can be provided that the motor vehicle of this family member separately and strikingly points out this fact when parking out of a garage. It can also be provided that another family member is advised, for example, to take speed limits seriously and to observe them. These examples show that different functions of the motor vehicle can be provided depending on the identity of the person. Different functions can thus be provided depending on the identity of the person. The function can also affect several components of the motor vehicle. A function or a set of functions that are available to the person can thus be provided individually for each person.

The invention provides a system with a key device and with a

Motor vehicle that has an evaluation unit. In addition, the system has a computing module external to the vehicle. The computing module external to the vehicle is provided by a cloud server. This system is characterized in that the

Key has an interface for wireless data transmission and the

Evaluation unit of the motor vehicle and / or the computing module external to the vehicle are designed to transmit the identity of the person or to receive data about the identity of the person on the basis of the data transmitted by the key. The evaluation unit of the motor vehicle can, for example, in an on-board network

Motor vehicle be integrated. The computing module external to the vehicle is provided by a cloud server. The data which the key can send wirelessly via the interface is preferably data relating to the identity of the person. This data can also relate to the biometric information about the person.

As a rule, this data is prepared accordingly for transmission and / or transferred into another format. For example, a person's voice can be saved and transmitted in an MP4 format. In a similar manner, other biometric information about the person can be stored and transmitted.

The key can thus transmit data via the interface or directly transmit the identity of the person to the evaluation unit or the computing module external to the vehicle. In those cases which involve a complex evaluation, provision is preferably made for the identity to be determined using the evaluation unit of the

Motor vehicle or the vehicle-external computing module is performed. In this way, data, in particular biometric information, can be transmitted via the interface to the computing module external to the vehicle or the evaluation unit of the motor vehicle so that this biometric information is evaluated there. In this case, the identity of the person is not determined by the control unit of the key. The determination of the identity of the person can thus be transferred to the evaluation unit or the computing module external to the vehicle. So that can

computing-intensive task can be outsourced from the key. It can

Accelerate determining the person's identity significantly.

The invention provides that the identity of the person with predetermined

Profile information relating to a configuration of predetermined vehicle parameters for the person is linked and the evaluation unit of the motor vehicle and / or the vehicle-external computing module are designed to control an electric motor of the motor vehicle based on the identified identity of the person such that the

predefined vehicle parameters with the predefined profile information

to match. The key interface can, for example, connect to the Internet. Thus, the key can have online connectivity. It is also possible that a connection to a mobile radio network, in particular a BTLE network, can be established via this interface. The predetermined profile information includes a configuration of predetermined vehicle parameters for the person. The predefined vehicle parameters relate in particular to settings of the driver's seat, a steering wheel, orientations of the exterior mirrors, a setting of the air conditioning system, a setting of

Infotainment system and other comfort and ergonomic settings. Predefined profile information can thus preferably be assigned to a specific person.

The profile information thus ideally contains those settings

or configuration values for the specified vehicle parameters, which are provided for the person. This can be done, for example, by the person himself selecting the predetermined vehicle parameters and storing them in the profile information. If the identity of the person is determined by the evaluation unit or by the computing module external to the vehicle, the electric motor is activated. The control of the electric motor or several electric motors takes place preferably such that the given profile information of the person is realized. This means that the electric motor or the several electric motors are controlled in such a way that the specified vehicle parameters correspond to the stored profile information. For example, for a small person, a different seat height or steering wheel position can be set than in comparison to a taller person. Depending on the identity of the person, a different radio station or a different volume of the infota system can be set.

These vehicle parameters are set in accordance with the specified profile information. The specified profile information thus stores, for example, which seat height, steering wheel position, volume, radio station, etc. are provided. With the aid of such a system, it is possible to determine the identity of the person and thus adjust a motor vehicle individually to the person. The motor vehicle can thus be personalized for the person concerned. This is particularly helpful for drivers who change regularly, since in this case it is no longer necessary to manually set the specified vehicle parameters. In the area of car sharing, in particular, it is thus possible to set the predetermined ones in a complex manner

Vehicle parameters for the person concerned are omitted.

The invention provides a system that is characterized in that the

Computation module external to the vehicle has a neural network and the computation module external to the vehicle is designed, using the neural network, the biometric

Process information to identify the person. Determining the identity of the person can take up a lot of computing capacity. The key cannot always accomplish this task in a timely manner appropriate for the person. In this case, it may make sense to transfer such computation-intensive or complex tasks to the computing module external to the vehicle. Since the computing module external to the vehicle has a neural network, it can improve and develop itself over time. This means that biometric information can be processed faster and more efficiently. Establishing the identity of the person can thus be accelerated or simplified.

A further embodiment of this invention provides a system which is characterized in that the evaluation unit of the motor vehicle is designed to regularly scan a predetermined area around the motor vehicle with regard to the presence of the key. When scanning, an electromagnetic field is preferably built up around the motor vehicle. The evaluation unit can therefore be configured to use a electromagnetic field to search for keys located nearby in a regular or cyclical manner. This process is often referred to as polling. If the key is within the predetermined range, the evaluation unit can determine this key based on a change in the electromagnetic field or on the basis of a signal reflected or generated by the key, the presence of the key. The person can thus already be detected or recognized before entering the motor vehicle. This makes it possible to initiate or carry out personalization of the motor vehicle in advance. With

Personalization here is the setting of the vehicle parameters according to the

Profile information meant.

The invention also provides a method for acquiring biometric information of a person using a key for a motor vehicle, the key having a sensor system. The method is characterized by step a). In step a), biometric information about the person is recorded. This is done using the sensor system. The explanations for the preceding examples and the embodiments apply mutatis mutandis to this method.

The invention provides that an image of the person is recorded using a camera and / or a gait profile of the person is recorded using an acceleration sensor in order to obtain the biometric information of the person. Another variant of this invention provides that a fingerprint is recorded using a fingerprint sensor and / or a voice of the person is recorded using a microphone in order to obtain the biometric information of the person. The sensor system can accordingly have different sensors in order to record the biometric information of the person. The camera can be used to capture an image or a photo of the person. A head or face of the person is preferably photographed. A surface that is designed as a fingerprint sensor can be arranged in a predetermined area on the key. If the person touches this predetermined area, the fingerprint sensor can detect a fingerprint of the person. The acceleration sensor can detect a person's gait profile, even if the person does not touch the key directly. If the key is only carried by the person, a gait profile can still be recorded using the acceleration sensor. This is the case, for example, if the person has the

Carries car keys in a pocket or a handbag. It can be provided that the person uses a button to activate the microphone to enter the Speak microphone. Such a button is often referred to as a "push-to-talk" button. The person can be identified using the voice recorded in this way. This can be done, for example, by analyzing the voice accordingly.

The invention provides that the identity of the person based on the biometric

Information is determined. As a rule, biometric information uniquely characterizes a person. Was the biometric information or more

If biometric information is recorded, the person can be identified. The identity of the person can be determined by a control unit of the key or by another computing unit. The other computing unit can be, for example, an evaluation unit of the motor vehicle or a computing module of a cloud server external to the vehicle.

Another variant of this invention provides that several different biometric information has been recorded by the person and that the person's identity is determined as a function of this several biometric information.

Not all biometric information can always be clearly assigned to a specific person. For example, two people can have a similar gait profile. In this case, an analysis of the voice or a picture of the person can bring complete clarity about the person's identity. This can increase the reliability of identifying the person. Preferably, the biometric information that is used to determine the identity is the least

Computational effort required. If biometric information is not sufficient to reliably determine the identity of the person, then usually other biometric information is used to determine the identity.

The invention provides that an electric motor of the motor vehicle is controlled and a predetermined vehicle parameter is set based on the identity of the person. The predefined vehicle parameter generally relates to those functions of the motor vehicle which the person can operate or on which the person can act. The predefined vehicle parameter can be, for example, a volume, a radio transmitter, a seating position, an orientation of the exterior mirrors, opening a vehicle door or a trunk lid, or another similar setting. The predetermined vehicle parameter preferably corresponds to a desired setting of the person. The invention provides that the set vehicle parameter is saved as profile information. For example, a desired seating position in the

Profile information must be stored. Further settings relating to the motor vehicle can also be stored in the profile information as the respective vehicle parameters. The profile information can thus include several vehicle parameters. The

Vehicle parameters can relate in particular to an operation of the motor vehicle. For example, it can be stored with a specific person that a sports suspension is to be activated while the motor vehicle is traveling. An ambience of the vehicle can also be stored in the profile information. For example, it can be stipulated that a sporty or a calming vehicle atmosphere should be provided for a specific person. This can be implemented, for example, by correspondingly different illumination of the vehicle interior. The associated lighting settings can be stored in the respective vehicle parameters. The profile information can thus include a setting relating to the lighting or illumination of a vehicle interior. Different vehicle parameters can thus be stored in the profile information and the motor vehicle can thus be individually adjusted to the person.

Another variant of this invention provides that a sitting position of a

Vehicle seat, a radio station, an ambient light, a position of one

Vehicle steering wheel and / or an alignment of vehicle mirrors can be set as a vehicle parameter as a function of the identified identity and the set vehicle parameter is stored as profile information. The seat position of the vehicle seat can be set, for example, using the associated electric motor. A control unit of an infotainment system can set the radio station and the ambient light. Another electric motor relating to the vehicle steering wheel can adjust the height or orientation of the vehicle steering wheel according to the identity of the person. The same applies to the alignment of the

Vehicle mirror. The motor vehicle can thus be individually adjusted to the person, so that, ideally, the person does not have to make any further settings.

Another variant of this invention provides that the vehicle parameter is set before the person gets into the motor vehicle. So far, the applicant is only aware that setting the vehicle parameters is only possible when the person has already got into the motor vehicle. If the identity of the person is established before the person reaches the motor vehicle, the vehicle parameter can already be set before the person gets into the motor vehicle. This eliminates the annoying adjustment of the seat height or the exterior mirrors or other components. Especially in the area of car sharing offers, this can save a considerable amount of time. It can also significantly increase the comfort of car sharing offers. This is because the motor vehicle can be adjusted to the person in question before it reaches the motor vehicle.

The invention provides that the profile information is stored on a cloud server and the key connects to the cloud server in order to synchronize the profile information of the key with the profile information of the cloud server. This is particularly advantageous if the person in question changes the

Profile information. The changed profile information can thus also be used accordingly in other motor vehicles. The person in question only has to change the profile information once. Since the key connects to the cloud server, the changed profile information can also be used in other motor vehicles.

The invention will now be explained in more detail by way of example with reference to the accompanying drawings. It shows:

Fig. 1 is a schematic representation of a key device with a

Key; and

2 is a schematic representation of a system which a cloud

Servers, a motor vehicle, the key device and a person; and

Fig. 3 is a schematic representation of an everyday situation in which the key is used.

1 shows an example of a key device 10, which comprises a key 14 and a sensor system 19. The sensor system 19 has several

different sensors. 1 belong to the sensor system 19 of FIG

Microphone 16, an acceleration sensor 18, a camera 13 and a

Fingerprint sensor 17. In addition, the key 14 has a touch display 15. A person 20 can use the touch display 15 to make entries in the Actuate key device 10. Using an interface 11, the key 14 can connect to other components. For example, an online connectivity or a BTLE connectivity can be established using the interface 11.

In the case of FIG. 1, the key 14 also has a key bit 12. The key bit 12 can be used to mechanically open or activate a motor vehicle 21. The double arrow indicated on the key bit 12 is intended to represent that the key bit 12 can be stowed in a recess of the key 14.

From the point of view of the applicant, it is still not possible to automate the personalization of the motor vehicle 21 before the person 20 is seated in the motor vehicle 21. In the case of the keys known to date, it cannot be recognized which person is using the vehicle key 14.

So far, it is only known that the personalization of the motor vehicle 21

or the setting of the vehicle parameters depending on an identity of the person 20 is only possible via buttons in the door. In addition to the seating position, a steering wheel position can also be stored in the motor vehicle 21. It is also possible to select a profile in an infotainment system in previous motor vehicles 21. Profile settings relating to person 20 can be stored there. The

Personalization is only possible, however, when the person 20 in the

Motor vehicle 21 sits and presses the corresponding button in the door. This means that the person 20 has to wait until they are seated in the motor vehicle 21

or until the associated infotainment system has started up. Using the key 14, however, biometric information about the person 20 can be recorded in advance. It is also possible to determine their identity in advance. If the identity of the person 20 can be established in advance, it is also possible to implement the corresponding profile settings in the motor vehicle 21 before the person 20 gets into the motor vehicle 21.

Previous serial keys lack a sensor system that can clearly identify the person 20. If, for example, a family shares the motor vehicle 21 and always uses the same key 14, the system does not know whether, for example, a father, a mother or another family member is using the motor vehicle 21. 2 shows an example of a system 30 which comprises the person 20, the key 14, the motor vehicle 21 and a cloud server 25. In the example of FIG. 2, the person 20 carries the key 14 in one hand. In this case, a control unit 27 of the key 14 can use the camera 13 to take an image of a face of the person 20. The person 20 can generally be clearly identified with the aid of the image captured in this way. If this does not succeed, for example because of bad ones

In light conditions, the control unit 27 can use further sensors of the sensor system 19 in order to obtain biometric information about the person 20.

In the example of FIG. 2, the control unit 27 could request the person 20 to speak a keyword via the touch display 15. For example, "Hey Mercedes" could be provided as a keyword. Other keywords such as "Hey Daimler" are also possible. If the person 20 speaks the key word in the direction of the microphone 16, the control unit 27 can carry out a sound or frequency analysis of the voice based on the recorded voice of the person 20. This tone or frequency analysis can be compared with a given voice profile. Based on this comparison, the control unit 27 can determine the identity of the person 20. The control unit 27 could use the touch display 15 to ask the person 20 to place a finger on the fingerprint sensor 17. A person could thus obtain a fingerprint that can be compared with a predefined fingerprint. The default

Fingerprint is preferably stored on a memory module of the key 14.

If the person 20 did not hold the key 14 in his hand, but rather transported it in a pocket or in another pocket, the identity of the person 20 could still be determined via the acceleration sensor 18. As a rule, each individual person 20 has a very specific gait profile. This gear profile can be detected by the acceleration sensor 18. Would the

Acceleration sensor 18, for example, detect an extremely slow movement of the person 20, this could indicate that an older person is aware of this

Motor vehicle 21 approaches.

The identity of the person 20 can be transmitted to an evaluation unit 22 of the motor vehicle 21 via the interface 11 of the key 14. It is possible for data on the biometric information to be transmitted to the evaluation unit 22 or to a computing module 24 external to the vehicle via the interface 11. The Dashed lines in Fig. 2 indicate data transmission. The of the

Evaluation unit 22 arrows outgoing to the electric motors 23 indicate corresponding control signals. The evaluation unit 22 can control the electric motors 23. The biometric information can then be evaluated by the evaluation unit 22 of the

Motor vehicle 21 or by means of the computer module 24 external to the vehicle to determine the identity of the person 20. Based on this, the

Control unit 22 control the corresponding electric motors 23, which is indicated by the solid arrows. Thus, the motor vehicle 21 can adjust to the person 20, so to speak personalize himself. Via the interface 11, however, the identity of the person 20 to the evaluation unit 22 or to the

computing module 24 external to the vehicle are transmitted. This would occur above all if the control unit 27 of the key 14 can directly determine the identity of the person 20.

If several possible profile settings are stored for the person 20, these different profile settings can be offered to the person 20 by means of the touch display 15. For example, the person 20 can select different driving modes. A driving mode relates to a basic driving behavior of the

Motor vehicle 21 and an ergonomic design of a vehicle interior of the motor vehicle 21. The person 20 could, for example, between the

different relaxation modes, relaxation, encouragement or sport. In the case of the relaxation driving mode, for example, soothing light could be used. In the driving mode sport, exciting light could be emitted in the vehicle compartment of the motor vehicle 21.

The person 20 usually only has to set their profile once. It would only be necessary to adjust your profile settings if you wanted to make changes. The profile settings contain the configurations for the specified ones

Vehicle parameters. As a rule, the predetermined vehicle parameters relate to those functions which the person 20 can act on or which the person 20 needs to use the motor vehicle 21. These include, for example, opening vehicle doors or a trunk door, choosing a chassis, one

Illumination of the vehicle interior, a volume of an infotainment system, a preset radio station, a position of a steering wheel or a vehicle seat as well as a position or orientation of vehicle mirrors as well as settings for other vehicle components that are to be individually adjusted to the person 20. The list of vehicle parameters mentioned is not exhaustive. Alles this information can be stored in the profile information of the person 20. A change in this profile information is only necessary if the person 20 wishes to make a change. The profile information of the person 20 is preferably stored on the cloud server 25. The profile information relating to the person 20 can thus be transmitted to evaluation units for other motor vehicles. The control unit 27 of the key 14 ideally checks whether the profile information relating to the person 20 has to be synchronized with the information stored on the cloud server 25. If a deviation is found in this case, the person 20 can use the touch display 15 of the key 14 to synchronize the

Profile information on the key 14 are excited with the profile information on the cloud server 25.

3 shows an exemplary situation of how the key 14 can interact with the motor vehicle 21. 3 shows a door in the right area, which is provided with two curved arrows. These curved arrows are labeled a and b and represent different people. From the door to the motor vehicle 21, a path curve with several points P1 to P4 is indicated by way of example. This

Railway curve exemplifies the path of person 20 from the front door to that

Motor vehicle 21. At point P1, person 20 has left the building. At point P2, the person 20 is on the way to the motor vehicle 21. Since the person 20 carries the key 14 with him, the control unit 27 of the key 14 may have already determined the identity of the person 20. The motor vehicle 21 can with the help of

Evaluation unit 22 scan the surroundings of motor vehicle 21 for key 14. In the example of FIG. 3, this is done using a corresponding polling field. In the present example, a low-frequency polling field LF is used. From point P3, the evaluation unit 22 can detect the key 14. The

Control unit 27 can communicate the identity of the person 20 to the evaluation unit 22 via the interface 11. Profile information on person 20 is preferably stored in evaluation unit 22. With the help of this profile information it is known which

Components of the motor vehicle 21 in which way should be adjusted. For this purpose, the evaluation unit 22 can control different electric motors 23. For example, starting from point P3, motor vehicle 21 can adjust itself individually to person 20. For example, the exterior mirrors can be adjusted, one

Seat position can be adjusted and further settings regarding the operation and ergonomics of the motor vehicle 21 can be made. In addition, the

Evaluation unit 22 emit a light signal using a headlight of motor vehicle 21 as soon as key 14 reaches point P3. That is, the motor vehicle 21 ideally adjusts to the person 20 starting at point P3. In the best case, the motor vehicle 21 has adjusted itself individually to the person 20 before it reaches the motor vehicle 21.

In the example of FIG. 3, a person b would instead of a person a

Approach motor vehicle 21, many vehicle parameters can be set differently. In this case, the evaluation unit 22 will use the profile information on person b in order to change the settings contained therein

Implement vehicle parameters accordingly. The key 14 with his

Sensor system 19 is particularly advantageous in the case of car sharing offers. In the case of car sharing or car rental companies, it happens regularly that the motor vehicle 21 is used by different people 20. Each of these people 20 would like the motor vehicle 21 to be optimally adjusted to them. With the aid of this key 14, the identity of the person 20 can now be determined before the person 20 reaches the motor vehicle 21. Customer-specific wishes and settings of motor vehicle 21 can thus be made in advance before person 20 gets into motor vehicle 21. Manual adjustment of the seating position or the exterior mirrors or other components can thus be omitted. The time required to adjust the motor vehicle 21 to itself can thus be reduced considerably. Thus, several different people 20 can share the motor vehicle 21 and can still be sure that the motor vehicle 21 is adjusted to their needs.
