Description

The invention relates to a method for adjusting a position of a vehicle part of a vehicle, in particular a vehicle seat and / or a rearview mirror and / or a steering wheel.

Vehicle parts such as vehicle seats, rear view mirrors or steering wheels can usually be changed in their position in order to adapt them to usage habits or the dimensions of a user of the vehicle. The adjustment of these vehicle parts is usually made by the user himself. The user is typically anxious to be able to assume a comfortable position when using the vehicle and therefore often aligns the vehicle parts in the most comfortable position possible. However, such an orientation does not necessarily have health benefits. For example, it is possible that a driver's comfortable seating position is associated with an unhealthy back posture that can lead to back pain in the long run.

Against this background, the task is to assist the user of a vehicle when setting a vehicle part of the vehicle in a health-promoting position for a user of the vehicle.

The object is achieved by a method for adjusting a position of at least one vehicle part of a vehicle, in particular a vehicle seat and / or a rearview mirror and / or a steering wheel, wherein a virtual actual model of a seated user of the vehicle is generated, wherein a virtual target Model of the seated user of the vehicle is generated, and wherein a position of the vehicle part is set in dependence on the actual model and the target model.

In the method according to the invention, a virtual actual model of the seated user is generated, in particular an anthropometric actual model of the seated user. This virtual actual model represents the actual state of the user of the vehicle when sitting, i. It takes into account possible incorrect postures or misalignments of the body parts of the user. The method also provides a virtual target model of the seated user which is ergonomically desirable, i. advantageous attitude of the user when sitting in the vehicle represents. These two virtual models of the seated user are used to adjust a position of one or more vehicle parts, for example a vehicle seat and / or a rear-view mirror and / or a steering wheel. The method makes it possible to determine an adjustment of the at least one vehicle part selected on the basis of a current, possibly unhealthy, actual attitude of the user in order to accustom the user to a health-promoting posture while sitting in the vehicle.

According to an advantageous embodiment of the invention, the virtual actual model of the seated user is generated as a function of a virtual actual model of the standing user. This procedure offers the advantage that the virtual actual model of the standing user can be determined from one or more camera shots of the standing user. In the state anthropometric sizes of the user can be determined with less effort than would be the case in the user's sitting position. In the generation of the virtual actual model of the seated user, interior data of the vehicle can additionally be used, for example data on the geometry of the interior and / or the geometry of the respective vehicle part and / or the arrangement of the respective vehicle part in the interior. In this respect, the virtual actual model of the seated user can be generated on the basis of the actual model of the standing user and the interior data.

It is preferred if the virtual actual model of the standing user is determined as a function of a frontal camera recording of the standing user and / or a lateral camera recording of the standing user. Preferably, on the basis of such camera recordings of the standing user, parameters of the virtual actual model of the standing user are extracted. Particularly preferably, additional variables are used to determine the virtual actual model of the standing user, for example the age of the user, the size of the user, the weight of the user and / or the gender of the user. These additional variables can be queried by the user, for example, by a computer program.

An embodiment in which the front camera recording and / or the lateral camera recording is generated by means of a camera of a mobile terminal, in particular of a smartphone, has proved to be particularly advantageous. The camera shot of the user can be taken from a predetermined distance by another person. The use of a mobile terminal allows an uncomplicated determination of the virtual actual model of the standing user without it being necessary to use special detection devices, for example 3D scanners. Furthermore, the mobile terminal can have an input device, via which the aforementioned additional variables can be entered. Preferably, the mobile terminal has a data processing device, for example a Microprocessor on, by which a processing of the camera recordings and / or an extraction of the parameters of the actual model can be done from the camera recordings.

In this context, it is advantageous if the virtual actual model of the standing user is stored on a mobile terminal carried by the user, in particular a smartphone, and is preferably transmitted to a control device of the vehicle. The transfer of the virtual actual model from the mobile terminal to the control device can be wired and / or wireless. The stored in the mobile terminal actual model of the standing user can be carried by the user and transmitted as needed to the control device of a vehicle that the user wants to use. This makes it possible to enable in different vehicles a health-promoting automatic adjustment of a vehicle part, for example a vehicle seat, for the respective user.

According to an advantageous embodiment of the method, the virtual target model of the seated user is generated as a function of a virtual target model of the standing user. In the generation of the virtual target model of the seated user, interior data of the vehicle can additionally be used, for example data on the geometry of the interior and / or the geometry of the respective vehicle part and / or the arrangement of the respective vehicle part in the interior. As such, the seated user's virtual target model may be generated based on the standing model of the standing user and the interior data.

Preferably, the virtual target model of the standing user is generated as a function of a virtual actual model of the standing user. In this case, statistical data are preferably used depending on the age and / or size and / or weight and / or gender of the user. The generation of the virtual target model of the standing user is preferably carried out by means of the data processing device of the mobile terminal.

It is advantageous if the virtual target model of the standing user is stored on a mobile terminal carried by the user, in particular a smartphone, and is preferably transmitted to a control device of the vehicle. The transfer of the virtual target model from the mobile terminal to the control device can be wired and / or wireless. The stored in the mobile terminal target model of the standing user can be carried by the user and transmitted as needed to the control device of a vehicle that the user wants to use. This makes it possible to enable in different vehicles a health-promoting automatic adjustment of a vehicle part, for example a vehicle seat, for the respective user.

According to an advantageous embodiment, provision is made for setting the position of the vehicle part to determine at least one first position parameter value as a function of the actual model of the seated user and to determine at least one second position parameter value as a function of the set model of the seated user. In the case of vehicle parts which have a plurality of degrees of freedom or in the case in which the position of a plurality of vehicle parts is adjusted, it is preferable to determine a plurality of first position parameter values as a function of the actual model of the seated user and a plurality of second position parameter values as a function of the set model of the seated user , The first position parameter values define a position of the vehicle part or parts which is adapted to the actual model of the seated user. On the other hand, a position of the vehicle part or parts which is adapted to the set model of the seated user is defined via the second position parameter values. The second position parameter values thus define a health-advantageous setting of the vehicle parts or parts.

For adjusting the position of the vehicle part, a particularly interpolated intermediate parameter value is preferably determined which lies in the range between the first position parameter value and the second position parameter value. In the case of vehicle parts which have a plurality of degrees of freedom or, in the case in which the position of a plurality of vehicle parts is adjusted, preferably a plurality of intermediate parameter values are determined. The one or more intermediate parameter values define a position of the vehicle part that is shifted from the position of the vehicle part defined by the actual model of the seated user toward the position described by the target model. This offers the advantage that the user can be offered a position of the vehicle part, which is more advantageous in terms of health.

In this context, it is particularly advantageous if the intermediate parameter value is shifted in the direction of the second position parameter value after a predetermined period of time has elapsed. By doing so, it becomes possible to shift the setting of the position of the vehicle part with time more and more in the direction of the health advantageous position, which is defined by the target model of the seated user. So it is not necessary the user directly with the health advantageous position of the vehicle part to confront. Rather, the user can be accustomed to the health advantageous position by moving the position in the direction of the beneficial health position over a predetermined period of time.

Preferably, the virtual models of the user, ie the virtual actual model of the standing user and / or the virtual target model of the standing user and / or the virtual actual model of the seated user and / or the virtual target model of the seated user , Data on the geometry of the body parts, in particular the dimensions of the body parts, data on the relative position of the body parts to each other, data on the weight of the body parts or the entire body.

According to an advantageous embodiment of the invention it is provided that the vehicle has a plurality of vehicle seats designed as vehicle parts, wherein a plurality of vehicle seats each assigned a user, wherein for each user of the vehicle, a virtual actual model of the seated user and a virtual target model of the seated User is created, and wherein a position of the user assigned vehicle seat is set in dependence on the actual model and the target model.

In the 1 is are two sitting positions of a user 1 , in particular driver, of a vehicle 2 shown. In the upper half of the presentation is the user 1 in an ergonomically advantageous and healthy safe seating position. The lower half of the diagram, however, shows a sitting position in which the cervical spine 1.1 of the user 1 located in a misalignment. This misalignment is due to a disadvantageous position of the rearview mirror 3 of the vehicle 2 due. With the present invention, it is possible for the user 1 to assist in taking the healthful sitting position shown in the upper half.

The 2 shows an interior of a vehicle 2 with several vehicle parts 3 . 4 . 5 . 6 to illustrate setting options for the positions of the vehicle parts 3 . 4 . 5 . 6 , The vehicle parts are a rearview mirror 3 , a side rearview mirror 4 , a steering wheel 5 as well as a vehicle seat 6 , These vehicle parts 3 . 4 . 5 . 6 can be spent with the method according to the invention in a position that promotes an ergonomically advantageous attitude of the user.

According to 3 is a user, in particular driver, a vehicle in a sitting position on a vehicle seat 6 , If the user 1 An incipient scoliosis is present, by deliberately adjusting the inclination of the seat 6.1 - as by the arrows 7 . 8th indicated - a malposition of the spine are counteracted while sitting.

The flowchart in 4 shows the individual method steps for determining a virtual actual model of the standing user and a virtual target model of the standing user. In a detection step 100 First, several camera shots of the user 1 generated. For this purpose, a camera of a smartphone designed as a mobile device 9 used. Are preferred - for example, by another person from a certain distance from the user 1 a frontal camera shot of the standing user 1 and a side camera shot of the standing user 1 generated. Furthermore, further personal data can be queried via the mobile terminal, eg the age, the size, the weight and / or the gender of the user 1 , In the registration step 100 Preferably, a software set up for capturing the camera recordings and / or querying the personal data of the user, in particular app, is used.

In a detection step 100 subsequent modeling step 101 determines a data processing device of the mobile terminal 9 based on the camera shots parameters of a virtual actual model of the standing user 1 , Here, for example, geometries, in particular lengths of individual body parts and / or the relative position of individual body parts to each other can be determined. Furthermore, the personal data queried in the detection step can also be used to determine the virtual target model of the standing user. As a result of the modeling step 101 becomes a virtual actual model of the standing user 1 received and stored in a memory of the mobile terminal 9 saved.

In a subsequent calculation step 102 will depend on the personal data of the user 1 used ergonomic statistical data. In another modeling step 103 then becomes a virtual target model of the standing user as a function of the virtual actual model of the standing user ( SEVB ) generated. The virtual target model of the standing user has the same geometries, in particular length specifications of the individual body parts, such as the actual model of the standing user 1 , In contrast to the actual model of the standing user 1 the target model of the standing user has an ergonomically advantageous posture. This means, in particular, that the relative position of individual body parts relative to one another is changed to the virtual target model of the standing user 1 to obtain. The virtual target model SEVB of the standing user 1 then comes together with the virtual actual model SPB of the standing user 1 in a memory of the mobile terminal 9 saved.

The mobile device 9 can by the user 1 be carried along to when using a vehicle 2 the automatic adjustment of vehicle parts 3 . 4 . 5 . 6 to allow according to a method of the invention. As in 5 shown on the mobile device 9 stored actual virtual model SPB of the standing user 1 and that on the mobile device 9 stored virtual target model SEVB of the standing user 1 to the vehicle 3 , In particular to a control device of the vehicle 3 transfer. The transfer of the virtual actual model SPB and the virtual target model SEVB from the mobile terminal 9 The control device can be wired and / or wireless. As will be explained below, a virtual actual model will be used sPB a seated user 1 and a virtual target model SEVB of the seated user 1 generated and a position of one or more vehicle parts 3 . 4 . 5 . 6 will depend on the actual model sPB and the target model SEVB set.

The virtual actual model sPB of the seated user 1 becomes dependent on the virtual actual model SPB of the standing user 1 and given interior data 104 of the vehicle 2 generates, for example, data on the geometry of the interior and / or the geometry of the respective vehicle part 3 . 4 . 5 . 6 and / or the arrangement of the respective vehicle part 3 . 4 . 5 . 6 in the interior. Similarly, the virtual target model becomes SEVB of the seated user 1 depending on the virtual target model SEVB of the standing user 1 and the given interior data 104 of the vehicle 2 generated.

For adjusting the position of the respective vehicle part 3 . 4 . 5 . 6 then become several first position parameter values 105 depending on the actual model sPB of the seated user 1 determined. About these first position parameter values 105 becomes a position of the vehicle parts 3 . 4 . 5 . 6 defined, which corresponds to the actual model sPB of the seated user 1 is adjusted. Further, several second position parameter values become 106 depending on the target model SEVB of the seated user 1 is determined. These second position parameter values 106 describe a position of the vehicle parts 3 . 4 . 5 . 6 that conform to the target model SEVB of the seated user 1 is adjusted. Below are the differences 107 between the first and second position parameter values 105 . 106 determined and several interpolated intermediate parameter values 108 determined.

The determination of the interpolated intermediate parameter value 108 is based on the illustration in 6 explained. 6 shows several position parameters 109.1 - 109-n used to adjust a position of a vehicle part 3 . 4 . 5 . 6 can be set to a position parameter value. Shown are first position parameter values 105 , based on the actual model sPB of the seated user 1 were determined and second position parameter values 106 , based on the target model SEVB of the seated user 1 were determined. To adjust the position of the vehicle parts 3 . 4 . 5 . 6 become several interpolated intermediate parameter values 108 . 108 ' is determined, which is in the range between the first position parameter value and the second position parameter value. These intermediate parameter values 108 . 108 ' be in the control of the vehicle 2 saved. There are first intermediate parameter values 108 closer to the first position parameter values 105 and second intermediate parameter values 108 ' are closer to the second position parameter values 106 , In this respect, the second intermediate parameter values form 108 ' a position of the vehicle parts 3 . 4 . 5 . 6 starting closer to the ergonomically advantageous position of these vehicle parts 3 . 4 . 5 . 6 is the first intermediate parameter value 108 , There can be several intermediate parameter values 108 be determined and stored. These different intermediate parameter values 108 . 108 ' can be sequentially adjusted to the position of the vehicle parts in chronological order 3 . 4 . 5 . 6 slowly the preferred position according to the second position parameter values 106 adapt. In this case, the selected intermediate parameter value is preferred 108 after a predetermined period of time has passed in the direction of the second position parameter value 106 postponed.

The various intermediate parameter values 108 are preferred in a memory of the vehicle 2 for the respective user 1 stored and on in a display device 12 of the vehicle is displayed, cf. 7 , The storage may depend on a seating position of the user 1 inside the vehicle 2 be done so that, for example, different positions can be set when the same user on a driver's seat 10 or a backseat 11 located.
