Description

The present invention relates to a method for determining the identity of a person in a seat, in particular a vehicle seat, a method for making at least one person-specific setting in a vehicle, a method for determining the authorization or non-authorization of a person to perform an action in a vehicle and an arrangement for detecting identity information of a person on a seat, in particular a vehicle seat.

In modern cars of the upper class and increasingly the middle class, it is common that numerous additional functions can be adjusted to the user. These are z. These are stored in profiles and can be loaded depending on the user. In addition, there are various safety-related settings that depend on the size of the driver, such. B. mirror and seating position. In this case, an identification of the driver or a recognition of the size is necessary. Various technical aids allow this, z. B. Keyless systems that are associated with a person, smartphone apps that tell the size of the vehicle, or camera-based systems that are mounted in the vehicle interior. Such autonomous systems are able to operate without user intervention. Similar profiles may also be relevant in shared work environments. Here, a personalization can be done that, for example, adapts frequently used applications, lighting and other environmental parameters.

There are two categories. Vision-based systems are based on cameras that observe the seat and recognize user activity. The disadvantages here are potential occlusions, since a line of sight is required and an adaptation of the camera parameters and filter algorithms is necessary due to rapidly changing light conditions. The second category is based on systems integrated into the seat. These use sensors that register the presence of a user. Pressure-sensitive systems require a mechanical coupling between the seat and the sensor. This mechanical coupling can change due to frequent use and is not very robust.

DE 10 2011 006 344 A1 describes an occupant sensing system for a vehicle comprising a pressure sensitive material installed in one or more pressure sensing zones in at least one vehicle seat. The pressure-sensitive material is configured to provide an electrical signal to a controller in pressure application, wherein the controller determines at least the presence, position, and / or classification of occupants based on the electrical signal.

DE 199 00 842 A1 , which is generic to an assembly of the present invention, relates to an occupant detection system comprising a plurality of electrode materials embedded in a seat back in an automobile, electric field generator means for generating an electric field around the electrode materials, a body approach device. Detecting means for detecting the approach of a human body to the electrode materials based on an electric current and a determining means for determining the presence or absence and the physique of a seated on the seat occupant. DE 199 00 842 A1 is aimed at detecting a posture via various sensor systems. However, people are not identified, but it is determined whether the occupant is an adult or a child and prevented from this information the operation of an airbag device.

DE 10 2005 004 683 A1 relates to a sensor device for detecting occupants of a motor vehicle, in particular for the activation of active safety devices by means of a plurality of arranged in the vicinity of inassenpositionen sensors which detect the electric field strength of their environment, and by means of an electronic control device for evaluating the detected sensor signals at least a subset of the sensors is associated with a seat of the motor vehicle. This is not about identifying a person.

DE 10 2012 216 178 A1 discloses a method of identifying an occupant of a vehicle sitting on a vehicle seat in which at least one fluid chamber is disposed, comprising the steps of: measuring, by at least one fluid pressure sensor, at least one pressure value in the fluid chamber; and identifying the occupant based on a comparison of the at least one pressure value with pressure value data stored for a number of persons in a database.

DE 103 42 929 A1 relates to a recognition device for occupant identification in a motor vehicle with at least one integrated in a seat of the motor vehicle sensor for detecting the force acting on the seat by an occupant force. A memory device is provided in which for at least one possible occupant the course of the force acting on the seat during a boarding process is stored, the time profile of the force acting on the seat during a current boarding process having at least one stored profile is compared and concluded from the comparison to the identity of the occupant.

The object of the invention is to provide an improved method for determining the identity of a person on a seat, in particular on a vehicle seat.

According to a basic idea of the invention, this object is achieved in that from a signal pattern which is generated on or by a plurality of electrodes, the pose, d. H. the position and orientation of a person on the seat, is detected. The signal pattern is generated when a person sits down on the seat, for example, a person to be identified. The determination of the pose is also referred to as pose detection. In the pose recognition, the person taking the seat is assigned a pose. The assignment of, for example, by comparison with comparative data, z. B. comparison signal patterns that were determined with one or more persons, wherein the person to be identified does not have to be one of those persons with whom comparative data were determined.

The recognition of the pose is preferably still personunspezifisch, d. H. the identity of the person is unknown after determining the pose. Preferably, after the recognition of the pose, the identification of the person is made in a further step.

The combination of pose detection and identification helps to avoid misrecognition, such as. B. may occur in persons of different body sizes. Thus, the invention improves the security of the identification. Without a pose detection in accordance with the present invention, two different people in a different pose on the seat could create a same signal pattern, thereby making it difficult or impossible to make a clear identity determination. The pose detection according to the present invention avoids this disadvantage. According to the invention, an identity determination is thus carried out not only on the basis of a signal pattern, but on the basis of a pose detection in combination with a signal pattern, in particular an individual signal pattern, which is generated by the person to be identified.

According to a further idea of the invention, the detection of a person is not by means of pressure sensors, but by means of distance sensors, in particular capacitive sensors, which may be mounted under a seat surface and so do not limit the design of the seat surfaces. Capacitive systems can be fully integrated, need no line of sight and are not disturbed in the dark or in glare.

In principle, the invention offers the possibility of optimizing the method or subsequently described devices for pose detection or identification on the basis of current measurement data and to improve the performance of a method according to the invention or of an arrangement according to the invention.

Also possible is a mutual communication between devices or modules with which the method is feasible, such as measuring device, evaluation, pose detection device and identification device, whereby the performance of both a pose detection and identification is improved.

The invention relates to a method for determining the identity of a person on a seat comprising

• Providing a seat having a plurality of electrodes which are integrated in the seat and distributed over a planar area,
• Placing a person on the seat, generating signals at a plurality of the electrodes, and the strength of the individual signals depends on the distance of the skin surface of the person to the electrode in question, so that a signal pattern is obtained,
• Determining the person's pose from the signal pattern,
• Comparing the signal pattern with known signal patterns for the detected pose, wherein each of the known signal patterns is assigned to a person of a specific identity,
• - Establishing the identity of the person in the seat in case of a positive result of the comparison.

The seat is in particular a vehicle seat, preferably a seat in a rail vehicle or motor vehicle, such as a car, truck, or bus.

The pose indicates the position and orientation of a person on the seat, in other words a posture.

The method steps are explained in detail below:

a) Providing a seat and placing a person on the seat

The electrodes are integrated into the seat so that a person sitting on the seat does not touch the electrodes directly. The electrodes are arranged below a surface, for example a cushion surface. The term "under a surface" includes any depth of placement below the surface, for example, in a deeper layer of a seat assembly. Preferably however, the electrodes are integrated into the seat near the surface of the seat.

For example, the electrodes are distributed over a seat surface and / or seat back and / or arm rest of the seat, wherein beneath the surface of the seat, e.g. B. are arranged distributed under a seat surface, a seat back surface and / or armrest surface. The term "over" refers to the distribution over a particular area and below the seating surface. The electrodes may be incorporated into a cushion layer or a fabric layer, or may be disposed directly below a coating substance.

According to the invention, the electrodes interact with one or more sensors. A sensor is set up for detecting or measuring a measured variable, in particular a capacitance. Sensors are configured to register suitable bodies that approach the electrode (s) over a certain distance in cooperation with the electrode. The electrode is made of a conductive material or comprises a conductive material. The electrodes may be formed in various forms, for example as a conductor wire or conductor strip. A conductor wire or conductor strip may be formed in various forms, for example bent, straight, looped, etc.

The sensor is, in cooperation with one or more electrodes, in particular a capacitive sensor, preferably a capacitive proximity sensor or a capacitive pressure sensor.

Electrodes are preferably arranged in a regular pattern next to one another and / or one above the other. For example, elongated electrodes can be arranged parallel to one another. Loop-shaped electrodes may for example be arranged side by side and one above the other. The term "arranged side by side" means that the electrodes are distributed side by side over a surface, in particular a surface of a seat back, a headrest, a seat surface and / or a surface of an armrest.

A plurality of layers (also referred to as "layers") of electrodes may be arranged in a seat, each layer being constructed of electrodes arranged next to one another. Several layers of electrodes are preferably equidistant from each other.

When a person is placed on the seat, signals are generated at several of the electrodes, the strength of which depends on the distance of the skin surface of the person to the electrode in question. Also, no signals can be generated at one or more electrodes if no body part of the person is in sufficient proximity to such an electrode. A signal pattern is a spatially resolved information about which of the electrodes signals are generated, optionally to which of the electrodes signals are not generated, and preferably also how strong the signal generated on an electrode is. When a person approaches an electrode, the capacitance of the electrode changes. A sensor or a signal processing device can excite electric fields at one or more electrodes and continuously measure the resulting capacitance or a quantity derived from the capacitance, e.g. As a voltage measure. In particular, the measurement of the capacitance relative to the environment by the electrodes takes place in a sensor. In particular, in a signal processing device, also referred to as a measuring system, a digitization of the measured variable, a filtering of the measured variable and / or a normalization of the measured variable.

b) determining the person's pose from the signal pattern

This method step can be performed by or in an evaluation device, in particular a pose detection device, also referred to as a pose detection module, which is part of the evaluation device. The evaluation device, especially the pose detection device, can provide information about the detected pose.

From the signal pattern, a pose of the person sitting on the seat and to be identified is determined. The determination is preferably carried out on the basis of comparative data of a plurality, in particular a plurality, persons who have taken seat in at least one previously defined, predetermined and / or known pose on the seat and their signal pattern (also referred to as comparison signal pattern) in this at least a given pose has been determined and saved. The person to be identified need not be part of the plurality or plurality of persons. The majority or multiplicity of persons need not be known by their identity. For example, comparison data with a plurality of persons can be determined by a manufacturer of a vehicle. The comparison data can be stored in the vehicle, in particular in an evaluation device or a pose detection module, in particular be deposited by a manufacturer, and later for the identification of persons, such as specific users of the vehicle (owners, owners, buyers, their family members, friends, etc.). ), serve.

In a particular pose, the associated signal patterns may be a plurality or a plurality People have similarities or typical poses that can be used to identify the pose of the person whose identity is to be determined. The concretely generated signal pattern of a person placed on the seat whose identity is to be detected may be compared with a plurality or plurality of signal patterns each associated with a particular pose, and the pose of the person to be identified may be recognized therefrom.

A minimum degree of similarity of the signal pattern of the person to be identified with the signal patterns of the plurality or plurality of persons can be defined so that the comparison, by definition, yields a positive result and a pose is recognized. A minimum degree of similarity to pose-typical features of the signal pattern of the person to be identified can be defined with pose-typical features of the signal patterns of the plurality or plurality of persons.

When comparing signal patterns, it is generally possible to define a minimum degree of similarity, a minimum degree of correspondence or a maximum deviation. A threshold or threshold may be defined that expresses a minimum similarity or minimum match, for example, a threshold / threshold in percent. This is also true in this invention more generally when signal patterns are compared for any purpose. A minimum degree of similarity or a maximum deviation can be determined using a heuristic method or a heuristic. Heuristic methods for determining a degree of similarity or agreement are known to those skilled in the art.

• – Bereitstellen eines Sitzes, der mehrere Elektroden aufweist, welche in den Sitz integriert und flächig verteilt angeordnet sind,
• – Platzieren einer Mehrzahl oder Vielzahl Personen nacheinander auf dem Sitz, und in zumindest einer definierten, vorgegebenen und/oder bekannten Pose, sodass für jede Person ein Signalmuster für die zumindest eine definierte, vorgegebene und/oder bekannten Pose erhalten wird,
• – Zuordnen der Signalmuster, die durch die Personen erzeugt werden, zu der definierten, vorgegebenen und/oder bekannten Pose, bei der das jeweilige Signalmuster erhalten ist.

When assigning a pose of the person to be identified to the signal pattern of the person to be identified, so-called pose classification information can be used, which is obtained from one, but preferably from several persons, in one or more previously defined, predefined and / or known poses. Pose classification information may be obtained by a method of acquiring information for classifying a pose of a person in a seat, comprising

• Providing a seat having a plurality of electrodes which are integrated in the seat and distributed over a planar area,
• Placing a plurality or a plurality of persons successively on the seat, and in at least one defined, predetermined and / or known pose, so that a signal pattern for the at least one defined, predetermined and / or known pose is obtained for each person,
• Assigning the signal patterns generated by the persons to the defined, predetermined and / or known pose in which the respective signal pattern is obtained.

With this method, a plurality or a plurality of signal patterns (comparison signal patterns) can be generated with which the signal pattern of the person to be identified is compared. The method can be used to obtain one or more typical signal patterns, from one or more persons, for one or more poses, the signal patterns being each associated with a pose. Thus, a plurality of signal patterns can each be obtained for a plurality of defined, predefined and / or known poses, wherein the signal patterns are preferably obtained from a plurality of persons. The obtained pose classification information may be stored in a classifier adapted to recognize different poses, for example a number n of different poses.

• – Rücken angelehnt oder Rücken nicht angelehnt
• – Rücken oben angelehnt
• – Rücken unten angelehnt
• – Kopf angelehnt oder Kopf nicht angelehnt
• – linker Arm auf Armlehne aufgelegt oder nicht aufgelegt
• – rechter Arm auf Armlehne aufgelegt oder nicht aufgelegt
• – gerade sitzend oder schräg sitzend
• – vorne auf der Sitzfläche sitzend oder hinten auf der Sitzfläche sitzend

The method and number of possible poses on which the method according to the invention is based is in principle not limited. It is advantageous to do a certain typing of poses and to limit the number of possible poses. Exemplary poses have any combination of two or more traits:

• - Back ajar or back not ajar
• - Leaned back up
• - Leaned back down
• - Head ajar or head not ajar
• - left arm resting on armrest or not hanging up
• - right arm on armrest or not hung up
• - sitting straight or sitting diagonally
• - Sitting on the front of the seat or sitting on the back of the seat

Some of the postures mentioned can, as will be readily apparent, be taken merely as an alternative. Other of the features may be additive.

c) comparing the signal pattern with known signal patterns for the detected pose

This method step can be carried out by or in an evaluation device, in particular an identification device, also referred to as an identification module, which is part of the evaluation device. The evaluation device, in particular the identification device, can provide information about the identity of the person to be identified.

Following the above-described assignment of a person's pose to the signal pattern generated by that person, in the person's identity determination process, the comparison of that signal pattern with known, preferably stored, signal patterns for the (or at) that associated pose, each of the known signal patterns a person is associated with a particular identity. A signal pattern in which pose and identity of the person generating the signal pattern is known or associated is also referred to as a "pose identity signal pattern".

In assigning or determining the pose of the person to be identified from the signal pattern described above under b), comparison patterns of different persons in different poses can be compared and the pose in question can be found out on the basis of typical signal pattern features. In this case, the specific signal pattern of the person to be identified does not yet have to be contained in the comparison signal patterns. In the above step b), a pose of the person to be identified is determined without being assigned to a specific person.

In the subsequent comparison in step c) of the generated signal pattern with known signal patterns, it is necessary that the signal pattern of the person to be identified for the determined pose in the comparison data or comparison signal patterns is present, or at least a similar pattern of the person in the comparison data is present if the determination of the identity of the person is to be made with a positive result.

An identity or a minimum degree of similarity of the signal pattern of the person to be identified with a known signal pattern may be required for the comparison to yield a positive result by definition. If no identity of signal patterns is required, a minimum degree of similarity, a minimum degree of agreement or a maximum deviation can be defined. A threshold or threshold may be defined that expresses a minimum similarity or minimum match of signal patterns, for example, a threshold / threshold in percent. A minimum degree of similarity or a maximum deviation can be determined using a heuristic method or a heuristic. In a heuristic, the similarity of the recorded pattern with the comparison patterns can be defined. Such a method is similar to an identification using an identical pattern, but it can be worked with coarser differences. Heuristic methods for determining a degree of similarity or agreement are known to those skilled in the art.

In step c), person-specific signal patterns for the pose determined in b) are used in the comparison, i. H. Signal pattern for this determined pose, to each of which now the identity of the signal pattern-generating person known and / or associated. Signal patterns for another pose, to each of which the identity of the signal pattern-generating person is also known and / or associated, can be disregarded.

The pose of the person to be identified from the signal pattern determined previously in b) thus has the function of a filter, since in the next comparison step c) only the associated pose is used. Signal patterns for poses that are not recognized in b) are thus not considered further in the method.

• – Bereitstellen eines Sitzes, der mehrere Elektroden aufweist, welche in den Sitz integriert und flächig verteilt angeordnet sind, wie oben bereits erläutert
• – Platzieren einer Person auf dem Sitz, in zumindest einer definierten, vorgegebenen und/oder bekannten Pose, wobei an mehreren der Elektroden Signale erzeugt werden, und die Stärke der einzelnen Signale vom Abstand der Hautoberfläche der Person zu der betreffenden Elektrode abhängt, sodass ein Signalmuster erhalten wird,
• – Eingabe einer Identitätsinformation der Person
• – Zuordnen einer Pose zu dem Signalmuster,
• – Speichern einer Zuordnung von (i) einer Identitätsinformation der Person, (ii) zumindest einer Pose der Person und (iii) zumindest einem der Pose zugeordneten Signalmuster, auch bezeichnet als Posen-Identitäts-Signalmuster.

In one embodiment of the invention, in the step c) is compared with sensor signal profiles, each sensor signal profile having the identity information of a person, at least one pose of the person and at least one signal pattern associated with this pose. The sensor signal profile is assigned via the identity information of a specific person. The sensor signal profile, also referred to as a capacitive profile, can be obtained by a method comprising:

• - Providing a seat having a plurality of electrodes which are integrated into the seat and arranged distributed over a surface, as already explained above
• Placing a person on the seat, in at least one defined, predetermined and / or known pose, whereby signals are generated at a plurality of the electrodes, and the strength of the individual signals depends on the distance of the skin surface of the person to the respective electrode, so that a signal pattern is obtained
• - Input of identity information of the person
• Associating a pose with the signal pattern,
• Storing an association of (i) identity information of the person, (ii) at least one pose of the person, and (iii) at least one of the pose associated signal patterns, also referred to as a pose identity signal pattern.

In this method for acquiring an individual sensor signal profile, the pose of the person known by identity is assigned to the signal pattern generated in this pose. For a particular person whose identity is detected, so the signal pattern associated with a pose is known and can be used for comparison in the identity determination. It is possible to assign multiple signal patterns to a pose. For example, a slightly altered posture may still correspond to a defined pose, but result in a slightly altered signal pattern. A capacitive profile or a sensor signal profile of a certain person on the seat can thus have multiple signal profiles, each associated with a particular pose.

In the method for acquiring a sensor signal profile of a person on a seat, when assigning a pose to the signal pattern in an alternative process design, signal patterns of other persons in different poses can be compared to find out the pose.

In a specific variant of a method for detecting a sensor signal profile of a person on a seat, the person is placed in various poses on the seat and the assignment for this person has several poses and a plurality of signal patterns, wherein the signal patterns are each assigned to a pose.

• – Wiederholen des Erzeugens eines Signalmusters für eine Pose, für die ein Signalmuster bereits vorliegt, durch die Person zu einem späteren Zeitpunkt,
• – Ergänzen und/oder Abändern des Signalmusters, oder Erzeugen eines weiteren Signalmusters, für die Pose, und/oder
• – Wiederholen des Verfahrens für eine andere Pose.

An individual sensor signal profile or capacitive profile can be applied either dynamically or statically. In a further embodiment of a method for detecting a sensor signal profile of a person on a seat, the method has one or more of the steps:

• Repeating the generation of a signal pattern for a pose for which a signal pattern already exists, by the person at a later time,
• Supplementing and / or modifying the signal pattern, or generating a further signal pattern, for the pose, and / or
• - Repeat the procedure for another pose.

In this variant of the method, a capacitive profile or sensor signal profile for a person can be modified or supplemented, in particular refined. An identification device can be supplied with new data and / or trained with regard to the function.

In repeating the generation of a signal pattern for a pose at a later time, altered postures of a person may be detected. A time-dependent conversion of the signal profile of a specific person for one or more specific poses can be detected.

When supplementing, modifying the signal pattern or generating a further signal pattern, a correction or refinement of a capacitive profile with respect to a pose can take place, wherein the addition, modification or generation of the signal pattern does not necessarily have to take place at a later time.

In repeating the process for another pose, a person's capacitive profile is supplemented with another, previously unrecognized pose.

Further methods of the invention will be described below which are based on the identity determination method described above.

• – Durchführen eines Verfahrens zur Feststellung der Identität einer Person auf einem Sitz wie vorangehend beschrieben,
• – Vornehmen einer personenspezifischen Einstellung in dem Fahrzeug auf Grundlage der Identitätsfeststellung.

In a further aspect, the invention relates to a method for carrying out at least one person-specific setting in a vehicle, comprising

• Performing a method for determining the identity of a person in a seat as described above,
• Making a person-specific attitude in the vehicle based on the identity determination.

With the method, one or more devices of a vehicle can be activated, deactivated, released or disabled, and / or the manner of operation of at least one device can be set or determined.

The term "adjustment" conceptually includes the activation or deactivation of a device of a vehicle, and / or the making of at least one setting in which manner the device is to be operated. The latter is also referred to as a specific setting of a device. For example, a navigation device can be activated or deactivated. Further, a specific setting of the apparatus may be made, such as a display mode, the setting of a destination, etc.

With this method, settings in the vehicle can be individually adapted to a specific person, for example to a driver, but not necessarily only to a driver. Exemplary personal settings are selected from a sitting position, an immobilizer setting, a setting of one or more mirrors, a steering wheel adjustment, a landing gear setting, an assistance system setting, a speakerphone setting, a radio setting, a music player setting, a setting Multimedia device, a setting of a TV-display device, a setting of a navigation device, an air conditioner setting. As can be seen, the adjustment of the seating position, a multimedia device or an air conditioning system can affect any seating position, not just that of a driver. Examples of assistance systems are: traffic light assistant, trailer stability program, anti-lock braking system, traction control, attention alert, hill start assist, downhill assistance, brake assist, electronic damper control, parking assistance, electromechanically powered power steering, electrohydraulically driven Power steering, electronic differential lock, electronic stability control / vehicle dynamics control, high beam assistant, cruise control, intelligent speed assistance, collision warning and protection system, adaptive cornering light, automatic light, engine drag torque control, night vision assistant, emergency brake assist, autonomous emergency braking system, emergency stop system, tire pressure monitoring system, reversing system, windscreen wiper automatic, lane detection system, Lane departure warning, lane change assistant, lane change assistance, traffic sign recognition and tilt control. The identity-specific setting can be, for example, an adjustment as to whether a vehicle device, in particular an assistance system, is switched on or not, and / or in which manner or in which setting an assistance system is to be operated.

Depending on the person of the driver, for example, a special profile can be stored. The profile may include information as to which of the facilities is being used by that person or not, or desired or not, or how the facility should be operated. After identity determination of the person according to the inventive method, the devices concerned can be activated or not activated, and optionally a desired setting can be selected, for example by evaluation and / or activation and / or loading the profile.

The person-specific attitude, in particular the person-specific profile can contain information about the manner in which a vehicle device is to be operated. In a radio, for example, a person-specific a desired station can be set. In a music playback of a direction, for example, a specific music can be selected person-specific. Furthermore, a person-specific volume can be set in a music playback device or a radio. In a navigation system, a person-specific list of specific travel destinations and / or a person-specific setting, for example the navigation mode or the type of display, can be selected. In an air conditioner, for example, a desired temperature, a desired ventilation mode and / or a desired person-specific ventilation strength can be set. The exemplary list of these person-specific settings is not exhaustive.

• – Durchführen eines Verfahrens zur Feststellung der Identität einer Person auf einem Sitz wie vorangehend beschrieben, wobei der Sitz ein Fahrzeugsitz ist,
• – Feststellen, ob die identifizierte Person zur Vornahme zumindest einer bestimmten Handlung in dem Fahrzeug autorisiert ist, und/oder feststellen, ob die identifizierte Person zur Vornahme zumindest einer bestimmten Handlung in dem Fahrzeug nicht autorisiert ist
• – Ermöglichen der Vornahme der Handlung durch die Person, wenn die Person autorisiert ist oder keine Nicht-Autorisierung festgestellt wurde, oder Verwehren der Vornahme der Handlung durch die Person, wenn keine Autorisierung der Person festgestellt wurde oder eine Nicht-Autorisierung festgestellt wurde, und

In yet another aspect, the invention relates to a method for determining authorization or unauthorization of a person to perform an action in a vehicle

• Carrying out a method for determining the identity of a person on a seat as described above, wherein the seat is a vehicle seat,
• - determining whether the identified person is authorized to perform at least one particular action in the vehicle, and / or determine whether the identified person is unauthorized to perform at least one particular action in the vehicle
• - allowing the act to be performed by the person if the person is authorized or unauthorized, or denying the act by the person if no authorization of the person has been found or a non-authorization has been detected, and

• – Mitteilung der zumindest einen Handlung, zu der die Person autorisiert ist, und/oder Mitteilung der zumindest einen Handlung, für welche die Person nicht autorisiert ist.

The method may further comprise:

• Notification of the at least one act to which the person is authorized and / or notification of the at least one act for which the person is not authorized.

The method for determining the authorization or non-authorization of a person to perform an action in a vehicle may be performed alternatively to a method of making a person-specific adjustment as explained above, or cumulatively performed with a method of making a person-specific attitude. For example, in the method of making a person-specific attitude, the attitude may be related thereto, or depending on whether authorization has been established or not established. For example, a device of the vehicle may be activated, deactivated, enabled or disabled when authorization has been determined or not detected. The combination of authorization or non-authorization on the one hand and activation, deactivation, release or blocking on the other depends on the type of facility. For example, a non-authorization may result in an immobilizer being activated, but a music player being disabled. It may be in the method for making a person-specific attitude, a make at least one setting in which way to operate a device of the vehicle depending on whether an authorization was found or not found.

In a variant of the invention, the action to be authorized or not to be authorized is the starting and / or driving of the vehicle, wherein starting and / or driving is made possible when the authorization is established, or starting and / or driving is prevented when a non-authorization is detected. Thus, with the method For example, an immobilizer of the car are person-specific controlled. If the identified person is not authorized to drive the vehicle, the immobilizer can be activated.

In general, an already described sensor signal profile or capacitive profile can be stored in a memory, the memory being arranged, for example, in the vehicle. Alternatively or additionally, a sensor signal profile may be stored in a memory supplied or carried by an authorized person, for example a token or smartkey, which is the case in particular in a method for determining the authorization or non-authorization of a person to perform an action. Should the memory carried by the person be lost, for example due to theft, an additional person-specific feature, for example a pin code, can be interrogated via a method for identifying the person according to the present invention. For example, a thief who has acquired a mobile memory with the sensor signal profile of a person by requesting additional person-specific information, such as a pin code, are prevented from starting and moving the vehicle.

In other variants of the invention, the action may relate to the manual operation of a setting, for example adjustment of a seating position, adjustment of one or more mirrors, steering wheel adjustment, suspension adjustment, adjustment of an assistance system, adjustment of a handsfree device, adjustment of a radio Setting a music playback device, a setting of a multimedia device, a setting of a TV-display device, a setting of a navigation device, an air conditioner setting or an assistance system. For example, an unauthorized child may be denied setting or adjusting the seating position, mirror, steering wheel, etc. Also, a music player or a multimedia device may be disabled with the method for unauthorized persons, for example, for children. More specifically, the manner of operating a vehicle device may or may not be enabled. Thus, an unauthorized person can be denied to make a special station, a special music or a setting of a particular multimedia content or television program.

The invention will be described below with reference to exemplary embodiments. Show it:

1 a seat with electrodes in different views,

2 the overview of an inventive arrangement for detecting identity information of a person in a seat,

3 the representation of a method according to the invention for determining the identity of a person in a seat and

4 the representation of a method according to the invention for making at least one person-specific attitude in a vehicle or for determining the authorization of a person to perform an action in a vehicle.

The seat 1 in 1 has a seat 2 , a backrest 3 and a headrest 4 on. In the seat 2 are four electrodes 5 . 6 . 7 . 8th integrated and below the surface of the seat 2 , which is turned to a person, arranged. The electrodes 5 . 6 . 7 . 8th are shown only schematically, as well as other yet explained electrodes. In the back 3 are the electrodes 9 . 10 . 11 . 12 integrated and in the headrest 4 the electrodes 13 . 14 , As can be seen, all are electrodes 5 - 14 flat over the surface of the seat 2 , the backrest 3 and the headrest 4 distributed.

In the 2 is the seat 1 only schematically drawn by a dashed line. Exemplary are the electrodes 5 . 6 . 7 . 8th . 9 shown in the seat 1 are integrated, as in the 1 shown. The electrodes are shown only schematically and are, for example, conductor wire loops. The electrodes 5 - 9 are each with a sensor 15 . 16 . 17 . 18 . 19 electrically connected. In the sensors 15 - 19 a measurement of the capacitance relative to the environment by the measuring electrodes 5 - 9 , which are close to the body surfaces in the seat 1 are introduced. The sensors 15 - 19 are in turn with the measuring system 20 , also referred to as signal processing device coupled. sensors 15 - 19 and signal processing means 20 form the so-called Measuring device of an inventive arrangement. In the signal processing device 20 For example, the digitization of the measured variable from the sensors, the filtering of the measured variable and / or the normalization of the measured variable. The signal processing device 20 is with the evaluation device 21 coupled. The evaluation device 21 fulfills the following tasks: Communication of commands or information to a control device 22 , Execution of the pose recognition, execution of the identification, transformation of detected information, such as identity and pose in the control device 22 usable commands. For example, the control device 22 the control device of a car and the seat 1 is a car seat.

Takes a person on the seat 1 Place, then through the electrodes or to the electrodes 5 to 14 generates a signal pattern M. The signal pattern M is schematically shown in FIG 3 shown. The grid shown schematically in the signal pattern M represents a grid-like arrangement of electrodes which are in the seat 1 integrated and distributed over a wide area, in particular over the seat 2 , Lean 3 and headrest 4 , as in 1 shown. The individual in 1 shown electrodes 5 - 14 In each case, flat electrode fields could also be used, which is expressed, for example, by a finer screening in the signal pattern M. For the sake of simplicity, the example will be illustrated by means of fewer electrode signals, with reference to the structure in FIG 1 , For example, a person has taken seat in the seat and by sitting down at the electrodes 5 - 8th Signals generated. Furthermore, the person has only ajar with the lower back, so that at the electrodes 9 and 10 Signals are generated. The upper part of the back and the head are not ajar, so there are no signals at the electrodes 11 . 12 . 13 . 14 be generated. The signal pattern M not only provides information about which electrodes generate signals, but also how strong the signal is at each electrode. By increasing the number of electrodes can be a higher spatial resolution across the surfaces of the seat 1 be achieved.

The signal pattern M is via the sensors, not shown here 15 - 19 to the processing device, also not shown here 20 passed where the signal is processed. Subsequently, the signal is sent to the evaluation device 21 directed in the 3 is shown in dashed lines. The evaluation device 21 has the pose detection device 23 and the identification device 24 on. In the pose detection device 23 the person's pose is determined from the signal pattern M. In the pose detection device 23 For different poses PoA, PoB, PoC several signal patterns (comparison signal patterns) are stored. For the pose PoA these are the signal patterns Xa1, Xa2, Xa3, Xa4, Xa5, where others may be present. For the pose PoB these are the patterns Xb2, Xb2, Xb3, Xb4, Xb5 and for the pose PoC the signal patterns Xc1, Xc2, Xc3, Xc4, Xc5. Of course, further poses with associated typical signal patterns can be stored. A pose, such as PoA and associated signal patterns, represents classification information. Thus, in this example, in the pose detection device 23 three classification information or classification information records 25 . 26 . 27 saved. The poses PoA, PoB and PoC have previously been defined, given or known, for example by how a person sits down on the seat. The signal pattern indicated by the initial letter X in the pose detection device 23 are obtained by placing a plurality or multiplicity of persons, who need not be known by name or identity, and therefore marked X, on the seat in a defined, predetermined and / or known pose. The signal pattern generated in each case was assigned to the respective pose, such. B. the signal pattern Xa1 to the pose PoA, when a person X has taken in the pose PoA on the seat. The pose PoA could mean, for example, that a person is sitting on the seat, has completely leaned his back and the head also to the headrest 4 ajar. The signal pattern Xa2 may be obtained from another anonymous person in the pose PoA on the seat 1 Took a seat. The same applies to the signal patterns Xa3, Xa4 and Xa5. Following the same principle, various persons X were in the pose PoB on the seat 1 and the signal patterns Xb1, Xb2, etc. are recorded. The same applies to the pose PoC. In each case, the assignment of the signal patterns which are generated by the persons to the defined, predetermined and / or known pose in which the respective signal pattern is obtained takes place. The classification information 25 . 26 . 27 According to a very general idea of the invention, independently of this example, already by a manufacturer of the vehicle in which the seat 1 integrated, can be determined. For determination, a plurality or a multiplicity of unknown test persons can be consulted, preferably of different sex, height, body weight and / or age.

In the comparison, the result in this example is that the signal pattern M has the greatest correspondence with one or more of the signal patterns Xb1, Xb2, Xb3, Xb4, Xb5, and that the concrete person to be determined here by their identity is in the pose PoB on the seat 1 Took a seat. Here, the signal pattern M does not have to coincide exactly with one of the patterns Xb1, Xb2, etc. The signal patterns Xb1, Xb2, etc. can be evaluated with respect to typical features or pattern components that are typical of the pose PoB, and it can be stated that the specific signal pattern M of the person to be identified has the typical signal pattern features for pose PoB or more of these typical features for pose PoB than is the case for the typical features of poses PoA and PoC. Ie. in the typical features of pose PoA and pose PoC, the matches are smaller.

From the information obtained that the person to be identified with the signal pattern M in the pose PoB sitting on the seat, then the identification in the identification device 24 performed. The identification device 24 contains sensor signal profiles 28 . 29 . 30 , Each of the sensor signal profiles 28 . 29 . 30 contains an identity information of a specific person, here designated person P1, P2, P3. Furthermore, each sensor signal profile contains at least one pose of each person, in this example three poses, PoA, PoB and PoC for each of the persons. Furthermore, each sensor signal profile contains 28 . 29 . 30 for each of the poses PoA, PoB, PoC at least one associated signal pattern (pose identity signal pattern). Using the example of the pose PoA of the person P1, these are the signal patterns 1a1 and 1a2. A certain pose may be associated with a plurality of signal patterns, the deviations between the signal patterns usually being small. For example, at a later time, a signal pattern for a particular pose may be re-recorded and the later signal pattern slightly different from the original, and stored as another signal pattern. Alternatively, the former signal pattern, for example 1a1, may be replaced by the signal pattern 1a2. In yet another alternative, the signal patterns 1a1 and 1a2 may be combined. In addition to the signal pattern profiles shown 28 . 29 . 30 , which are each in the form of a data record, further signal patterns for other poses and / or other persons can be recorded at arbitrary times.

From the pose detection module 23 the information was obtained that the person to be identified who generated the signal pattern M is in the pose PoB. Now be in the identification device 24 for different persons known to their identity, a further comparison is based on the signal patterns in pose PoB only. These signal patterns are in the 3 marked in bold. For example, in person P1 the pose PoB corresponds to the signal pattern 1b1, the person P2 in pose PoB to the signal patterns 2b1 and 2b2 and the person P3 in PoB to the signal patterns 3b1 and 3b2. The signal patterns for the poses PoA and PoC thus remain out of consideration for each of the stored persons. The comparison with the signal pattern M of the person to be identified shows that the signal pattern M either coincides with the signal pattern 2b2 of the pose PoB of the person P2 or has the most matches with this signal pattern. It may be required according to a general idea of the invention, which is not limited only to this embodiment, an identity or a minimum degree of similarity, so that the comparison by definition yields a positive result. If no identity of signal patterns is required, a minimum degree of similarity or a maximum deviation can be defined. In this specific example, therefore, the comparison results in an identity of the signal pattern M with the signal pattern 2b2 or at least a very great similarity. From this, the information is obtained that the signal pattern M is associated with the person P2 whose identity is known. The method for determining the identity of the previously unknown person thus results in the person being the person P2. If there is no identity or sufficient match of the signal pattern M with one of the signal patterns for the pose PoB about a specific person, the procedure for determining the identity is inconclusive. In this negative case is likely for the as yet unknown person no sensor signal profile, analogous to 28 . 29 or 30 , saved. It is therefore advisable to perform a method for acquiring a sensor signal profile for this unidentifiable person to the data in the identification module 24 to complete.

The person P1, P2, P3 may be, for example, owners, owners or other specific users of a vehicle, in which the seat 1 is installed.

4 shows the flow of a procedure for determining the authorization or non-authorization of a person to perform an action in a vehicle. Also shown is a method for making at least one person-specific setting in a vehicle.

After according to the procedure after 3 the identity of the person P2 has been determined, P2 indicating the identity, is in 4 a forwarding of the identity information to the control device 22 , In the control device 22 are to several known persons, for example here the persons P1 and P2, profiles or profile information data 31 . 32 deposited. D1, D2, D3 and D4 indicate various facilities in the vehicle. D1 could be for example a navigation system. In the case of person P1, the profile indicates that the navigation system D1 is to be activated and brought into the special setting D1a. In person P2, the navigation system D1 is turned off. For example, D2 could be a seat adjustment. For the person P1, the seat should be placed in the special setting D2a, for the person P2 in the setting D2b. With a seat D2, there is no basic on or off state, since a seat is always present. The device D3 could for example be an immobilizer. In the person P1, the immobilizer is activated, in the on state, so that the person P1 is denied the driving of the vehicle. In the person P2, the immobilizer D3 is put in the off state, so that the vehicle can be started. The device D4 could, for example, be a music reproduction device which is switched off at the person P1 and activated at the person P2 and brought into the special setting D4c. Otherwise, in the profiles 31 . 32 be specified or deposited with other facilities of the vehicle, with an activation / deactivation indication and / or a special setting.

In the present example, the person was identified as person P2, so by the controller 22 in the corresponding devices D1-D4 the settings specified in the profile are made. The control 22 may send appropriate control signals to the devices to perform the desired activation / deactivation and the desired adjustments. As in 4 shown correspond to the settings of the devices D1-D4, which are below the controller 22 are drawn in the specifications of the profile 32 ,

In this example, as stated above, the device D3 relates to an immobilizer which is not activated in the case of the person P2. By filing the information "D3: off" in the profile 32 is in the profile 32 Defines that the person P2 is authorized to drive the vehicle. It follows that the person P2 is authorized to perform the action H, in this case the starting of the vehicle, this being indicated by the tick behind the action H in the 4 is marked. Furthermore, to a display device 33 sent the message that the action H is possible. Accordingly, the display device 33 that from the controller 22 the message to the person P2 who is on the seat 1 Took place, spent.

In a corresponding modification of the method according to 4 Person P1, if previously identified, would be denied action H because of the profile 31 the person P1 is determined that the immobilizer D3 is to be turned on. Insofar is in the profile 31 Defines that the person P1 is not authorized to drive the vehicle.
