Description

The invention relates to a method for operating person-specific adjustable components with electrical adjustment of a motor vehicle. Furthermore, the invention relates to a computer program product, a control device and a motor vehicle with such a control device.

Person-specific adjustable components with electrical adjustment of a motor vehicle may be vehicle seats, the steering wheel, armrests, footrests, lower leg supports, pedals, tables, device or cup holders, mirrors, air jets or sun visors.

Car seats are understood to be the seats installed in motor vehicles for the occupants in the motor vehicle. Depending on the type of vehicle used and the distinction between driver and passenger seats and also on the equipment level, the vehicle seats installed in motor vehicles can basically differ greatly.

Modern motor vehicles have vehicle seats that provide a large and increasing number of seat adjustments to ensure a comfortable and secure posture. At the same time, however, an increasing number of seat adjustment options adds complexity and makes it difficult for a person to find a desired seating position. In order to solve this problem, various prediction models have been developed for individually optimized seating positions within a motor vehicle.

From the US 9688163 and the US 5822707 It is known to collect and evaluate various personal data to determine a seating position.

Furthermore, it is known, using anthropometric data and interior dimensions of the motor vehicle, to predict the preferred sitting position of the respective person. However, most of these methods were not implemented. The reasons for this are personal preferences of the person, which were not considered for the calculation of an optimal seating position. Therefore, there is a deviation between the predicted seating position and the preferred seating position. In particular, the predictions of the person's upper body angle are inaccurate.

It is therefore an object of the invention to remedy this situation.

• - Einlesen eines Personendatensatzes repräsentativ für eine auf dem Fahrzeugsitz sitzende Person, wobei der Personendatensatz einen Präferenzdatensatz, ausgewählt aus einer Mehrzahl von diskreten Präferenzdatensätzen, enthält, und
• - Auswerten zumindest des Personendatensatzes, um einen Überführungsdatensatz zum Überführen einer Ausgangssitzposition in eine Zielsitzposition des Fahrzeugsitzes zu bestimmen.

The object of the invention is achieved by a method for operating person-specific adjustable components with electrical adjustment of a motor vehicle, with the steps:

• Reading a personal dataset representative of a person sitting on the vehicle seat, the personal dataset containing a preference dataset selected from a plurality of discrete preference datasets, and
• - evaluating at least the personal data record to determine a transfer record for transferring an initial seat position to a target seat position of the vehicle seat.

The person-specific adjustable components with electrical adjustment can be a vehicle seat, a steering wheel, an armrest, a footrest, a lower leg support, pedals (such as driving and / or brake pedal), a table, a device or beverage holder, a mirror (such as a rearview mirror), an air nozzle and / or a sun visor act.

The vehicle record is representative of a vehicle model. It is thus assigned to a respective vehicle type of a manufacturer.

The personal record describes the body dimensions and proportions of the person sitting on the vehicle seat. In addition, the personal record contains the preference record. The preference record was created by the person in advance, so before the o.g. Process in a precursor step. For this purpose, the person selected a preference data set from a plurality of discrete preference data records. The preference records may include pictorial representations of various postures. However, it could also be pictorial representations of the vehicle seat, words describing a posture, or words / terms describing adjustment options (such as backrest upright - reclined, etc.). Thus, each of the scaling records each represents a seating position. Thus, a preference of a person is detected and taken into account in determining the target seating position.

The personal data record with the preference data record can be entered or configured via an HMI (Human Machine Interface) of the motor vehicle. Alternatively, separate devices may be used for this purpose, such as personal computers or handhelds, which are configured for this purpose by an appropriate software. Handhelds are understood to mean portable, electronic devices with power supply via rechargeable batteries or batteries for different applications. They are so small and light that the person at the Use it in one hand. It can be eg a smartphone or a tablet computer.

By evaluating at least the personal data set with the preference data set, a transfer record is determined, with which servomotors of the components are controlled to transfer from an exit seat position, i. a position selected or found by the person to effect the target seating position corresponding to the preferred seating position. Further, further data and / or information may be included in the determination of the transfer record, e.g. the role or function of the person (driver or passenger), planned route according to a navigation device, travel time, such as long highway ride or short city trip, or levels of activity of the person, i. the person wants to relax or work.

With the methods, it is achieved in particular by the use of the preference data set that deviations between the predicted sitting position and the preferred sitting position can be reduced.

According to one embodiment, in a further step, a seated posture is determined by evaluating at least the vehicle data record and the personal data record with the preference data record. Thus, an intermediate step is inserted. For example, For example, the sitting posture can be used to visualize the person of the result of their previous input, such as on the HMI. In other words, seat posture determination is an intermediate step for predicting the seating position. So the input process can be simplified.

According to a further embodiment, a vehicle data record which contains limit values representative of the adjustment possibilities of the components is read in and evaluated. The vehicle record is representative of a vehicle model. It is thus assigned to a respective vehicle type of a manufacturer. Thus, the vehicle-specific structural limitations can be considered, such. different interior dimensions of the motor vehicle, such as e.g. different dimensions of the headliner.

According to a further embodiment, the personal data record contains not only the preference data record but also anthropometric and / or ethnographic data representative of the person. Thus, personal data concerning the body dimensions and the construction of the person can be considered.

According to a further embodiment, the personal data record with the preference data set is buffered in a database. It can be provided that the vehicle data record and / or the personal data record with the preference data record are stored in a e.g. cached and retrieved as needed so that these data are available across vehicles.

According to a further embodiment, the personal data record with the preference data set is wirelessly transmitted from an HMI to the database. Thus, the database can be in a different location than the HMI and the personal data record with the preference data record can be made available anywhere.

According to a further embodiment, the personal data record with the preference data record is transmitted wirelessly from the database to a control unit of the motor vehicle. Thus, the personal record with the preference record can be provided independently of the vehicle, i. these records are provided to the motor vehicle that the person is starting up, e.g. after identifying himself with a personal code.

According to another embodiment, repositioning of the component, e.g. by the person or another person, and taken into account in the determination of the transfer record. Thus, a loop is formed, wherein the changes made in the context of repositioning are a measure of a control deviation. Thus, deviations between the predicted sitting position and the preferred sitting posture can be reduced continuously more and more.

Furthermore, the invention includes a computer program product, a control unit and a motor vehicle with such a control unit.

In a first step S100 becomes in the present embodiment, a vehicle record FDS representative of the motor vehicle 2 z. B. from a data memory of the motor vehicle 2 read in and a personal record PDS with a preference record SDS from a person using an HMI 10 entered or configured.

The HMI 10 is a separate device, ie, it is not structurally with the motor vehicle 2 connected. The HMI 10 may be a personal computer or handheld, for example. Handhelds are understood to mean portable, electronic devices with power supply via rechargeable batteries or batteries for different applications. They are so small and light that the person can hold them in one hand when using them. It can be eg a smartphone or a tablet computer. Notwithstanding the present embodiment, the input via an interface of the motor vehicle 2 done, such as a touch display of a motor vehicle side infotainment system.

The HMI 10 is designed for wireless data transmission to the vehicle record FDS and the personal record PDS to a cloud-based database in the present embodiment 8th transferred to. This allows the database 8th are in a different location than the HMI 10 and / or the motor vehicle 2 ,

The vehicle record FDS is representative of the vehicle model of the respective motor vehicle 2 , ie brand, model and equipment. The vehicle record FDS has values for the dimensions of the interior of the motor vehicle 2 on, such as width of the interior or height of the headliner.

The personal record PDS describes the body dimensions and proportions of those on the vehicle seat 4 sitting person. For this purpose, in the present embodiment, the personal data record PDS anthropometric and ethnographic data representative of the person on.

The preference record SDS is created by the person by the person from a plurality of discrete preference records SDS a preference record SDS selects. Each represents the scaling records SDS each a seating position SP or a proposal for a seat.

Representations of the respective seating positions SP show the 3 to 5 , here pictorial representations of the vehicle seat 4 are reproduced. In the 3 are different seating positions SP or sitting posture suggestions that differ with respect to a torso angle.

The 4 shows different seating positions SP or sitting posture suggestions with different arm postures while the 5 shows different seating positions or sitting posture proposals with different leg posture.

In the 6 however, there are different seating positions SP or sitting posture suggestions presented, which are in terms of the height of a seat surface of the vehicle seat 4 differ.

The representations can eg on the HMI 10 be reproduced, for example, within a software menu for entering or configuring the preference data set SDS ,

The vehicle record FDS and the personal record PDS with the preference record SDS are then sent to the database via a wireless data connection 8th transferred and in one step S200 cached under assignment of a personal code for the person. Notwithstanding the present embodiment, the input via an interface of the motor vehicle 2 done, such as a touch display of a motor vehicle side infotainment system.

Thus stands the personal data record PDS with the preference record SDS now ready for retrieval, regardless of location. Furthermore, the personal data record PDS with the preference record SDS from a motor vehicle 2 be transferred to another, for example in the case of a vehicle change, such as car sharing.

If the person is a particular motor vehicle 2 an identification step may be provided in which the person identifies himself with a personal code. Thereupon the control unit stops 6 a wireless data connection to the database 8th forth and read in one step S300 the vehicle record FDS and the personal record PDS with the preference record SDS which are associated with the personal code.

Furthermore, in the present embodiment of a first module 12 of the control unit 6 the vehicle data record FDS and the personal record PDS with the preference record SDS evaluated to a sitting posture SH to determine the person. The sitting posture SH can be output and visualized, eg on the HMI or a display device of the motor vehicle 2 ,

The sitting posture SH then, if necessary after a requested confirmation by the person, in a further step S400 from a second module 14 of the control unit 6 evaluated to a transfer record UDS for transferring an initial seating position to a target seating position of the vehicle seat 4 to determine. The transfer record UDS is used to control the individual actuators of the vehicle seat 4 to drive to the vehicle seat 4 starting from the initial seating position to the target seating position.

Notwithstanding the present embodiment may also be provided that the vehicle record FDS and the personal record PDS with the preference record SDS be evaluated to direct - ie without the step S300 - the transfer record UDS to determine.

In addition, it can be provided that in a further step S500 from a third module 16 of the control unit 14 a repositioning of the vehicle seat 4 is detected by the person. The changes made become a repositioning record RDS summarized and via a wireless data connection to the database 8th transfer.

The repositioning record RDS can then together with the vehicle record FDS and the personal record PDS with the preference record SDS be read out and evaluated during another trip by the person. In other words, now flows next to the vehicle record FDS and the personal record PDS with the preference record SDS also the repositioning dataset RDS in the determination of the transfer record UDS so as to optimize the determination of the posture Sh.

The control unit 6 with the first module 12 , the second module, 14 and the third module 16 may include hardware and / or software components for performing the described tasks and / or functions.

This is especially true through the use of the preference data set SDS but also by using the repositioning data set RDS ensures that deviations between the predicted sitting position and the preferred sitting posture can be reduced.
