Description

The disclosure relates to methods for adapting adjustable components in a motor vehicle to a person's stature.

DE 10 2006 032 769 A1 discloses a device for optimizing parameters of vehicle internals as a function of anatomical parameters of a passenger, the anatomical parameters of the passenger being determined by means of a detection device having a camera and an image evaluation device. The object of the present disclosure is to increase the precision of a device for optimizing parameters of vehicle internals.

This object is achieved with the features of claim 1. The subclaims can be combined with one another in a technologically expedient manner and they each show further refinements. The description, in particular in connection with the figures, additionally characterizes and specifies the disclosure.

• • Erfassen einer Person mit einer zu einem Fahrzeuginnenraum gerichteten Kamera,
• • Generierung eines auf Abmessungen der Person basierenden Skelettmodells, gebildet aus Streben, wobei von benachbarten Streben aufgespannte Winkel aufgezeichnet werden,
• • Kalkulation von Sollpositionen der verstellbaren Komponenten basierend auf zu den Winkeln und den Abmessungen der Person ideal passenden Parametern,
• • Ausgabe eines Steuerbefehls zur Bewegung der Komponenten von einer Istposition in die Sollposition.

Accordingly, a method is provided for adapting adjustable components in a motor vehicle to a person's stature, with the method steps:

• Capturing a person with a camera directed towards a vehicle interior,
• Generation of a skeleton model based on dimensions of the person, formed from struts, angles spanned by adjacent struts being recorded,
• Calculation of target positions of the adjustable components based on parameters ideally suited to the angles and dimensions of the person,
• • Output of a control command to move the components from an actual position to the target position.

This enables precise adjustment of the adjustable components to the physiological conditions of the person. The components should be adjusted especially for the driver and front passenger. The components are moved from an actual position, in which the components are located, for example after entering the vehicle, to a target position. A reduction to a skeleton model of the person, formed from joints and struts determined in their length, enables a more precise and faster calculation of the target positions for adapting the components to the physiological conditions of the person.

The ideal parameters for the angles are ergonomic and ideal values, taking into account dimensions between the person, components and relationships.

In one embodiment, ideal angle ranges are stored as parameters (angle between an x-axis and a back, angle between an upper arm and a y-axis, angle between upper arm and forearm, etc.) and the setpoints are output so that the recorded angles on the Person (after adjusting the components) fall into the angular ranges. The angle ranges can be stored in a microprocessor unit in a predefined manner as ergonomic and safety-related ideal angle ranges.

According to this embodiment, the target positions are calculated by comparing stored ideal angle ranges and the angles of the person and then determining position and angle changes of the components, so that the angles lie within the ideal angle ranges.

The components can be the seat and the steering wheel, as well as vehicle installations specific to the driver, which must be in the person's field of vision, such as a head-up display. Head-up displays are usually adjustable. There are variants in which an image is projected onto the windshield. There are embodiments in which a transparent element is arranged on the dashboard in front of the windshield in the driver's field of vision. The position or projection angle of both variants may be adjustable. The components that the driver must have in view also include a speedometer unit and other displays arranged on the dashboard. A seat and a steering wheel must therefore be adjusted so that the driver can see the speedometer unit, the head-up display and other displays on the dashboard.

The camera can be located in an area of an interior rear-view mirror, close to a sun visor and / or to a human-computer interface arranged centrally on the dashboard.

The components can also include side mirrors and an interior rearview mirror, which are to be set so that the person can see things behind the vehicle.

2. b) eine Lage einer Rückenlehne,
3. c) eine Sitzlängenposition,
4. d) eine Neigung eines Sitzes,
5. e) eine Lordosenstütze,
6. f) eine Lenkradposition,
7. g) ein Lenkradwinkel, und
8. h) eine Höhe eins Gurtausbringers an einer B-Säule.

As already mentioned, the components also include:

1. a) a vertical sitting position (seat height),
2. b) a position of a backrest,
3. c) a seat length position,
4. d) an inclination of a seat,
5. e) a lumbar support,
6. f) a steering wheel position,

In one embodiment, the control command is intended to show instructions for adjusting the components of actual positions in target positions on a display, the display being such that the person can adjust the components manually or using muscle strength until the component is within a tolerance range the target position is. In these, even for less expensive vehicles without electrically adjustable components, the display of the desired positions allows the driver to make the optimal settings for the body size himself.

In the case of components that can be adjusted lengthways, such as the steering column or a longitudinal adjustment of the seat length position, a tolerance range around the target position means that the target position is considered to have been reached when the component is only a few centimeters, possibly only a few millimeters, from the target position. Otherwise there may be situations in which the component is always moved a little bit beyond the target position and the target position can only be set exactly with effort by lengthy moving the component back and forth. Customer or person satisfaction can be increased by providing a tolerance range. The tolerance range is derived from a transfer of the ideal angle range from the skeleton model to the component.

In one version, the control command is intended to show instructions for adjusting the components of actual positions in target positions on a display, the display being such that the person can adapt the components electrically to corresponding switches until the component is within a tolerance range around the Target position.

The display can be located on the dashboard or directly on corresponding electrical switches for setting the components.

In one embodiment, the control command is intended to show instructions for adjusting the components on a display, with the person being asked in a procedural step to confirm that the components are automatically set according to the desired position, after the person has confirmed this, the components be automatically electrically adjusted until each component is within a respective tolerance range around the target position.

As a result, the simultaneous adjustment of all individual components in which there is a deviation of the actual position from the target position is carried out.

• • kontinuierliches Erfassen einer Bestätigung, dass die Komponenten automatisch entsprechend der Sollposition eingestellt werden, anhand einer Befehlstaste,
• • Deaktivierung der automatischen Einstellung der Komponenten, wenn die Person die Befehlstaste loslässt.

The following method steps are additionally provided in further configurations:

• Continuous acquisition of a confirmation that the components are automatically adjusted according to the target position using a command key,
• • Deactivating the automatic setting of the components when the person releases the command key.

The command key can be shown symbolically on the display or as an actual physical key in the vehicle. The person must hold down the command key until the components have reached their target positions. When the person lets go, the components stop. This ensures that the person has full control of the movements of the seat, the steering wheel, the head-up display, the lumbar support, the exterior mirrors, the pedals, etc. at all times.

In a further embodiment, a position of a seat relative to the dimensions measured and a position of a back allow conclusions to be drawn about physical dimensions that are not detectable by the camera, such as thighs and lower legs.

The actual position of the components is known to a control unit in which the steps of the method are implemented. Because an area of the person captured by the camera is in a certain position and from the position of the seat surface in the longitudinal direction and seat inclination, an approximate angle of inclination in the pelvic area can be determined by a program stored in the control unit and implemented as software.

It can further be provided that the person is asked acoustically or, for example, on the display, to touch the steering wheel so that the angle between the upper arm and the forearm can be detected in this position. The angle is essential for optimal usability of the steering wheel.

It can further be provided that the person is asked to move acoustically or, for example, on the display, since programs for generating a skeleton model generally require comparison data of several images of a person in order to record the skeleton model exactly.

In a further development of the indirect detection, the use of a signal from a seat occupancy sensor arranged in the seat surface is provided in order to recognize whether the person is sitting flat on the seat surface.

As a result, relatively precise conclusions can be drawn at least on an angle between the thighs of the person and the upper body, and the skeleton model can be completed into areas not covered in order to enable a precise determination of target positions for the components.

As a result, the indirect determination of dimensions of the body parts not captured by the camera can be further developed. Provided that the legs are not angled too strongly upwards, which can possibly be evaluated by determining a flat support of the legs in the seat occupancy sensor, the force measuring device determines the dimensions that are important for determining the desired position, which are not recorded by the camera can, meaningfully added. The target positions of the components can in turn be determined precisely from the calculated dimensions. The person can also first be asked to press the brake pedal vigorously, which sometimes works better at certain angles and, accordingly, can indirectly infer from the determined force how the legs are angled.

An actual position is exemplary 501 of the seat cushion 208 shown with a solid line. A dashed line symbolizes the target position 502 . In principle, the same applies to every further adjustable component 201 , 202 , 203 , 204 , 205 , 206 , 207 , 209 , 210 , 211 , 212 , 213 , 214 , 215 , 216 . Each adjustable component can be moved from an actual position to a target position if the actual position deviates from a target position. To the target position 502 in angles E and location along the longitudinal axis 301 there is a tolerance around 503 Are defined. The skeleton model is made up of the body parts 105 , 106 , 107 , 108 , 109 , 110 with appropriate angles A1 , B1 , C1 , D1 . At least one angle is on a vehicle-related xy Coordinate system related (in this case the angles A1 , B1 , C1 ).

The following are shown as examples: a lower leg 110 , a thigh 105 , a back 106 , a shoulder region 107 , an upper arm 108 , as well as a forearm 109 . Furthermore, of course, a shoulder width, not shown, and a pelvis width, not shown, as well as the associated angles, are recorded.

A camera 401 is designed to measure the dimensions of the person described above 101 capture. The camera 401 is signal technology in a manner not shown with a microprocessor unit 402 connected. In the microprocessor unit 402 Means, not shown, are implemented which the microprocessor unit 402 enable several of the camera 401 captured pictures of the person 101 save and compare.

The microprocessor unit 402 is also designed to receive signals from the camera 401 , the seat occupancy sensor 408 as well as one in the pedal 210 arranged force measuring device 404 to record, at least temporarily store and process according to a method described herein. In the microprocessor unit 402 For example, a CPU can be designed to process commands that are implemented as a program stored in a memory system, to acquire input signals from a data bus and / or to output signals to a data bus. In the case of manual component adjustments, the data bus can be connected to the components in terms of signal technology, on the one hand to actual positions 501 to record and then in the event of a deviation of an actual position 501 from a target position 502 this from actual position 501 in target position 502 to move. An actual position is exemplary 501 a seat cushion 208 and a dashed target position 502 of the seat cushion 208 shown. Depending on the equipment variant of the motor vehicle, the method described here is for all further adjustable components 201 , 202 , 203 , 204 , 205 , 206 , 207 , 209 , 210 , 211 , 212 , 214 , 215 , 216 Applicable, that is, actual positions on the components and target positions can be created from the person 101 the components can be determined and if there is a discrepancy between an actual position and a target position 201 , 202 , 203 , 204 , 205 , 206 , 207 , 209 , 210 , 211 , 212 , 214 be moved to the corresponding target positions. Nevertheless, a large number of components 201 , 202 , 203 , 204 , 205 , 206 , 207 , 209 , 210 , 211 , 212 , 214 , 215 , 216 will be electrically adjustable, there are equipment variants in which these are only set manually by muscle strength or body weight and spring elements, not shown. In 2nd is a procedure for the adjustment of adjustable components 201 , 202 , 203 , 204 , 205 , 206 , 207 , 209 , 210 , 211 , 212 , 214 , 215 , 216 in a motor vehicle to a person's stature 101 shown. Procedural step 601 sees the recording of physical dimensions 105 , 106 , 107 , 108 , 109 , 110 one person 101 with the to a vehicle interior 302 facing camera 401 in front. The body parts 105 , 106 , 107 , 108 , 109 , 110 stored internally in the microprocessor unit as a simplified skeleton model, formed from joints 111 and striving 112 and with angles A1 , B1 , C1 , D1 . In the procedural step 602 become target positions 502 of the adjustable components 201 , 202 , 203 , 204 , 205 , 206 , 207 , 209 , 210 , 211 , 212 , 214 , 215 , 216 determined. The calculation is based on angles A1 , B1 , C1 , D1 , etc. of the person 101 ideally matching parameters. The parameters are set in parallel for each vehicle based on specific internal dimensions and the location of the components 201 , 202 , 203 , 204 , 205 , 206 , 207 , 208 209 , 210 , 211 , 212 , 214 , 215 , 216 in the microprocessor unit 402 saved (or downloaded from the Internet via update). Then takes place in process step 603 the issuance of a control command for moving the components, for example the seat cushion 208 from an actual position 501 in a target position 502 in one process step 604 . The control command can display the target positions 502 as instructions for adjusting electrically or manually adjustable components (for example an inclination E and a longitudinal position of the seat cushion 208 ) so that the person 101 in the process step 604 the seat cushion 208 can adjust manually and by muscle strength until the seat cushion 208 themselves within a tolerance range 503 around the target position 502 located. The calculation of the target positions 502 can be done by comparing stored ideal angle ranges A2 , B2 , C2 , D2 and the detected or calculated angles A1 , B1 , C1 , D1 and then in a determination of changes in position and angle of the seat cushion 208 so the angle A1 , B1 , C1 , D1 within the ideal angle ranges A2 , B2 , C2 , D2 lie. However, this is done analogously for each additional component, with their spatial relationship to one another and to the person 101 every change of a component 201 , 202 , 203 , 204 , 205 , 206 , 207 , 208 209 , 210 , 211 , 212 , 214 , 215 , 216 affects setpoints of each other. The determination of parameters and ideal angle ranges A2 , B2 , C2 , D2 can be done on the basis of ergonomic and safety-related aspects through empirical determination.

Instructions for adjusting the components can be found on the display 406 , on the head-up display (HUD) 214 , in a speedometer unit 410 or on switches for adjusting the components accordingly 3rd being represented.

Alternatively, the person 101 in process step 604 asked to confirm that the components 201 , 202 , 203 , 204 , 205 , 206 , 207 , 208 209 , 210 , 211 , 212 , 214 , 215 , 216 are automatically set according to the target position, after the person has confirmed this, the components 201 , 202 , 203 , 204 , 205 , 206 , 207 , 208 , 209 , 210 , 211 , 212 , 214 , 216 can be automatically electrically adjusted until each component is within a tolerance range around the respective target position.

In addition, it can be provided that the method step 604 only completed automatically according to the previous paragraph if the person 101 a command key 409 Holds down, the automatic setting of the components 201 , 202 , 203 , 204 , 205 , 206 , 207 , 208 , 209 , 210 , 211 , 212 , 214 , 216 stops when the person 101 the command key 409 lets go.

Furthermore, the person 101 acoustically or on the display, for example 406 be asked to move because programs to generate a skeletal model usually compare data from multiple images of a person 101 need to record the skeleton model.

Furthermore, the person 101 acoustically or on the display, for example 406 be prompted to the steering wheel 211 to grasp the angle in this position A1 between the x-axis and the forearm 109 and the angle B1 between the upper arm 108 and the y-axis can be captured. Ideal angles A1 and B1 are important for optimal ergonomic usability of the steering wheel 211 .
