Description

Technical field:

The invention relates to a method for automatically adjusting a passenger seat in a motor vehicle. The invention also relates to an adjustment system, a computer program and a machine-readable storage medium.

Background:

Adjustment systems for the front seats of a vehicle are known, which enable the front seats to be adjusted independently of one another. To do this, the front seats are adjusted either manually or electrically to adjust a seating position to a user's individual needs. For this purpose, each front seat can be individually adjusted in its position and its end position makes no reference to the other seat. Furthermore, an automatic adjustment of the headrest is known from the prior art, which, based on occupancy data of the seats, moves the headrest between a functional position and automatically adjusted to a lowered position to improve a driver's side view in the vehicle.

The pamphlet DE 10 2014 209 133 A1 discloses an interior assembly for a vehicle having a passenger seat with a headrest, a rear seat, seat occupancy sensors attached to the seats, a headrest position sensor, a motor for moving the headrest between its operative position and its lowered position, and a central control unit operatively connected to the sensors and the engine. The passenger seat head restraint, in one embodiment, is moved up from a stowed position to its operational position each time the presence of a passenger is sensed. According to another embodiment, the passenger seat head restraint is moved from an operative or upright position to a stowed or concealed position when the front seat is unoccupied and the rear seat is occupied.

Description:

The invention is based on the object of proposing an automatic seat adjustment which improves or enlarges the driver's field of vision in the vehicle. This object is achieved by a method having the features of claim 1, an adjustment system having the features of claim 9, a computer program having the features of claim 14 and a storage medium having the features of claim 15. Preferred or advantageous embodiments of the invention result from the dependent claims, the following description and/or the attached figures.

• - eine Sitzstellung eines Fahrersitzes erfasst wird;
• - eine Sitzbelegung des Beifahrersitzes und eines beifahrerseitigen Rücksitzes erfasst wird;
• - der Beifahrersitz in Abhängigkeit der Sitzstellung des Fahrersitzes und der Sitzbelegung des Beifahrersitzes und des beifahrerseitigen Rücksitzes in eine Ruhestellung verstellt wird, sodass ein aktiver Sichtbereich des Fahrers vergrößert wird.

The subject matter of the invention is a method for the automatic seat adjustment of a passenger seat in a motor vehicle, in which:

• - A seat position of a driver's seat is detected;
• - A seat occupancy of the passenger seat and a passenger-side rear seat is detected;
• - the front passenger seat is adjusted to a rest position depending on the seat position of the driver's seat and the seat occupancy of the front passenger seat and the rear seat on the passenger side, so that an active field of vision for the driver is enlarged.

In particular, a seat position means a position of the driver's seat in relation to a longitudinal direction of the vehicle. Optionally, however, the seat position can also be understood as a position, in particular an angle of inclination of the backrest of the driver's seat.

In particular, occupancy of the passenger seat and the rear seat on the passenger side is understood to mean occupancy by one person. Optionally, however, a distinction can also be made between occupancy by a person and an object, such as a baby seat, shopping basket or the like, as part of the detection of the seat occupancy. A rear seat on the passenger side is preferably to be understood as meaning the rear seat which is arranged directly behind the front passenger seat.

In particular, a rest position is to be understood as meaning a relative position for the front passenger seat that is fixed to the seating position of the driver's seat, into which the front passenger seat is automatically placed if this is permissible depending on the seat occupancy. An active viewing area is preferably to be understood as a viewing area in which an assumed driver can look around the vehicle in a seated position on the driver's seat by turning his head and/or body as much as possible. The field of vision preferably includes a field of vision of the assumed driver while driving and a field of vision from the side, including looking over the right and left shoulder.

The advantage of the invention is that the passenger seat can be optimally adjusted as a function of the seat position of the driver's seat in order to increase the driver's field of vision. By considering the seat position of the driver's seat and the occupancy data, an optimal seat position for the front passenger seat can be determined in which the front passenger seat releases the maximum possible field of vision to the outside when it is placed in the rest position. This results in an improved view from the vehicle, which contributes significantly to traffic safety.

In an optional embodiment, it is provided that for each seat position of the driver's seat, a rest position for the front passenger's seat relative to the seat position of the driver's seat is stored. A relative rest position is preferably to be understood as a position of the passenger seat which takes into account the seat position of the driver's seat on the one hand and the occupancy of the passenger seat and the rear seat on the passenger side on the other. Based on the relative rest position, the front passenger seat is preferably moved outside the driver's active field of vision or at least arranged within the active safety zone in such a way that it only slightly impairs the driver's lateral field of vision. In particular, a corresponding data record can be stored in which an associated rest position is assigned for each possible seat position. It is therefore a consideration of the invention to propose an automatic seat adjustment which is characterized by an optimal adjustment of the field of vision.

In a specification, it is provided that the front passenger seat is adjusted in the rest position such that the silhouette of the front passenger seat from the driver's point of view, viewed by an assumed driver, overlaps with the B-pillar of the motor vehicle. In particular, the seat backrest and/or the headrest are aligned with the B-pillar depending on the seat position of the driver's seat. Provision is therefore made for the front passenger seat, in the rest position, not to block a side view out of the side windows of the vehicle, or only to a small extent.

In a further possible embodiment, it is provided that the front passenger seat is moved into a rear rest position depending on the seating position of the driver's seat when the front passenger seat and the rear seat are unoccupied. In particular, the front passenger seat is adjusted in the rear rest position in such a way that the maximum possible field of vision is released. In the rear rest position, the passenger seat is preferably brought into overlap with the B-pillar, as already described above. In other words, the front passenger seat is brought into an optimal seating position depending on the seating position of the driver's seat, in which a maximum field of vision is released for the driver when the front passenger seat and the rear seat behind the front passenger seat are unoccupied. An automatic seat adjustment is thus proposed, which sets the optimal seat position for the front passenger seat, taking into account the seat occupancy.

Another possible implementation provides for the front passenger seat to be moved to the rear rest position depending on the seating position of the driver's seat if an object, in particular a baby seat, is detected on the front passenger seat and the rear seat is unoccupied. In particular, the vehicle has a suitable detection device in order to distinguish between the presence of the person or the object on the passenger seat. In particular, the front passenger seat is adjusted in the rear rest position in such a way that a maximum possible field of vision is released depending on the object arranged on the front passenger seat. An automatic seat adjustment is thus proposed which, when the seat is occupied, can differentiate between a person and an object arranged on the object and sets a corresponding seat position for the passenger seat.

In a further possible embodiment, it is provided that the front passenger seat is adjusted to a central rest position depending on the seating position of the driver's seat when the rear seat is occupied and the front passenger seat is unoccupied. In particular, the front passenger seat is arranged in the middle rest position between a front and a rear seat position or end position in relation to the longitudinal direction of the vehicle. Preferably, the front passenger seat or its silhouette in the middle rest position is arranged as far as possible outside the field of vision or at least arranged in the field of vision in such a way that it is not significantly restricted. In principle, the front passenger seat can always be moved to the middle seat position when the rear seat is occupied.

Alternatively or optionally in addition, a suitable detection device can be used to detect the presence of a person or an object, in particular a baby seat or child seat, in the rear seat, with the front passenger seat being adjusted to the central rest position when an object is occupied and when it is occupied by a person is adjusted to a front rest position or alternatively remains in its originally set seating position. An automatic seat adjustment is thus proposed which, by setting the central rest position when the rear seat is occupied, forms a compromise between the field of vision for the driver and comfort, in particular legroom for a person in the rear seat.

In a further specification, it is provided that a longitudinal position of the front passenger seat is required to move the front passenger seat into the rest position is adjusted. Alternatively or optionally in addition, a seat height of the front passenger seat and/or a seat back angle of the front passenger seat and/or a headrest height of the front passenger seat is adjusted to move the front passenger seat into the rest position. In particular, the front passenger seat is moved in the direction of a rear longitudinal position in the rest position in order to move the front passenger seat into the rear rest position. In particular, the front passenger seat is moved between a rear and a front longitudinal position in the rest position in order to move the front passenger seat into the middle rest position. Optionally, the seat backrest is adjusted to an upright position in the rest position, in which the seat backrest is at least approximately, partially or completely overlapping the B-pillar, depending on the seat position of the driver's seat and the seat occupancy of the front passenger seat and the rear seat. Optionally, the headrest can be retracted to the maximum possible position in the rest position. An automatic seat adjustment is thus proposed, which allows an optimal adjustment of the passenger seat in relation to the driver's field of vision.

An optional development provides that the adjustment of the passenger seat must be confirmed by the driver. In particular, a planned adjustment of the front passenger seat is displayed when the front passenger seat is unoccupied or occupied by an object and/or the rear seat is unoccupied or occupied by an object. In particular, a message is output, with the driver being able to decide on the basis of the message whether the adjustment of the passenger seat should be carried out or aborted. This ensures that the front passenger seat cannot be adjusted unintentionally.

A further object of the invention relates to an adjustment system which is designed and/or suitable for automatic seat adjustment of a seat arrangement in a motor vehicle. The adjusting system is preferably used to carry out the method as has already been described above.

The adjustment system includes an adjustment device which is designed and/or suitable for electric seat adjustment of the passenger seat. In particular, the adjusting device is designed as an electromechanical actuator, which is used to adjust the seat position of the passenger seat. Optionally, the adjustment system has a further adjustment device, which is used for electric seat adjustment of the driver's seat.

The adjustment system includes a first detection device, which is designed and/or suitable for detecting a seat position of the driver's seat. In particular, the first detection device is designed to detect the seat position by evaluating the positioning time of the further adjustment device. Alternatively or optionally in addition, the first detection device includes one or more sensors which are designed and/or suitable for detecting the seat position.

The adjustment system includes a second detection device, which is designed and/or suitable for detecting a seat occupancy of the passenger seat and a rear seat on the passenger side. In particular, the second detection device is designed to detect the seat occupancy based on an existing sensor system, such as Seat Belt Reminder (SBR) or Occupant Detection Mats (OCS). Alternatively or optionally in addition, the second detection device includes one or more sensors which are designed and/or suitable for detecting the seat occupancy and optionally for distinguishing between a person and an object, in particular an infant carrier, child seat or the like when a seat is occupied.

Furthermore, the adjustment system includes a control device. The control device is preferably designed as a control unit for electric seat adjustment. The control device is preferably connected to the adjustment device and possibly the further adjustment device by signaling. The control device has a control module, the control module being designed to generate an actuating signal for the adjustment device and possibly the further adjustment device. In particular, the adjustment device adjusts the seat position of the passenger seat on the basis of the actuating signal. The control device also has an evaluation module, the evaluation module being designed to generate a control command for the control module. The evaluation module is preferably designed as a software or hardware module.

According to the invention, the evaluation module is designed to generate the control command for the passenger seat, taking into account the seat position of the driver's seat and the seat occupancy of the passenger seat and the rear seat on the passenger side. In particular, the seat position data of the driver's seat and the seat occupancy data of the front passenger seat and the rear seat on the passenger side are correlated with one another and evaluated in order to determine a rest position of the front passenger seat and to transmit this to the control module via the control command. The adjusting device is designed to move the passenger seat into the rest position on the basis of the control command in order to increase the driver's active field of vision.

In one possible embodiment it is provided that the first detection device is a Has camera for image or video recording of the seat position of the driver's seat. In particular, the camera is arranged in the vehicle interior, with at least the driver's seat being arranged in a surveillance area recorded by the camera. In particular, the camera is connected to the evaluation module in terms of data technology, with the evaluation module being designed to evaluate the image data from the camera in order to determine a current seat position of the driver's seat.

Alternatively or optionally in addition, the first detection device has at least or precisely one position sensor for detecting the seat position of the driver's seat by sensors. In particular, the first detection device has a travel sonor for detecting the longitudinal position and/or a travel sensor for detecting a seat back inclination and/or a travel sensor for detecting the height of the headrest. The at least one displacement sensor is preferably connected to the evaluation module in terms of data technology. The evaluation module is designed to evaluate the sensor data from the at least one travel sensor in order to determine a current seat position of the driver's seat. Optionally, both the image data and the sensor data can be evaluated by the evaluation device in order to record the current seat position of the driver's seat. A detection device is thus proposed, which is characterized by a precise detection of the seat position of the driver's seat.

In a further possible embodiment, it is provided that the second detection device has a camera for capturing the seat occupancy of the front passenger seat and the rear seat on the passenger side by means of images or video technology. In particular, the camera is another camera arranged in the vehicle interior, with at least the passenger seat and the rear seat on the passenger side being arranged in a surveillance area recorded by the camera. Alternatively, however, the passenger seat and/or the rear seat on the passenger side can also be arranged in the monitoring area of the camera for detecting the seat position of the driver's seat. The evaluation module is preferably designed to evaluate the image data of the camera in order to determine a current seat occupancy of the passenger seat and the rear seat on the passenger side.

Alternatively or optionally in addition, the second detection device has at least one seat occupancy sensor for sensory detection of the seat occupancy of the front passenger seat and/or the rear seat. The front passenger seat preferably includes a first seat occupancy sensor for detecting the seat occupancy of the front passenger seat and a second seat occupancy sensor for detecting the seat occupancy of the rear seat on the passenger side. For example, the seat occupancy sensor can be formed by a pressure or weight sensor. The at least one seat occupancy sensor is preferably connected to the evaluation module in terms of data technology, with the evaluation module being designed to evaluate the sensor data of the at least one seat occupancy sensor in order to determine a current seat occupancy of the front passenger seat and the rear seat on the passenger side. Optionally, both the image data and the sensor data can be evaluated by the evaluation device in order to record the current occupancy of the passenger seat and the rear seat on the passenger side. A detection device is thus proposed, which is characterized by a precise detection of the seat occupancy of the front passenger seat and the rear seat bench on the passenger side.

In a further possible embodiment, the evaluation module is designed to distinguish between a person or an object arranged on the passenger seat, in particular a baby seat, on the basis of the detection data of the second detection device, and to generate a control command accordingly. In particular, the evaluation module is designed to distinguish between a seat occupancy by a person or an object on the basis of the image data. Optionally, an RFID sensor can be integrated as a further seat occupancy sensor in the front passenger seat and/or the rear seat, for example to identify an object such as a baby seat, child seat or the like, with the object being coded accordingly. Optionally, both the image data and the sensor data can be evaluated by the evaluation device in order to detect the current occupancy of the front passenger seat and the rear seat on the passenger side and to distinguish between occupancy by a person and an object. A control device is therefore proposed which additionally takes account of occupancy by a person or an object.

In a specific implementation, it is provided that the adjustment device is designed to adjust a seat height and/or longitudinal position of the front passenger seat and/or a seat backrest angle of the front passenger seat and/or a headrest height of the front passenger seat on the basis of the control command in order to move the front passenger seat into the rest position . In particular, the adjusting device is designed to adjust the longitudinal position and the seat back inclination and/or headrest height independently of one another in order to adjust the passenger seat into the rest position.

Another subject matter of the invention relates to a computer program, the computer program being designed to carry out the method for automatic seat adjustment if the Computer program is executed on a computer, a processor unit or the control device, in particular the evaluation module.

A further subject matter of the invention is a storage medium, the storage medium comprising the computer program as previously described.

Further features, advantages and effects of the invention result from the following description of preferred exemplary embodiments of the invention. show:

• 1 a schematic representation of a front area of a vehicle as an embodiment of the invention;
• 2 the front area in the same representation as 1 ;
• 3 a flowchart for a method for automatic seat adjustment for the vehicle according to 1 and 2 ;
• 4 an adjustment system for automatic seat adjustment for the vehicle according to 1 and 2 and for carrying out the method according to 3 .

Corresponding or identical parts are each provided with the same reference symbols in the figures.

the 1 and 2 each show a highly schematic representation of a front area of a motor vehicle 1 with a driver's seat 2 and a passenger seat 3 as an exemplary embodiment of the invention. The driver's seat 2 and the passenger seat 3 each have a seat back 4 with a headrest 5 attached thereto.

A driver 6 , in particular a head of the driver 6 , and his active field of vision 7 in relation to the direction of travel F are indicated schematically on the driver's seat 2 . The active viewing area 7 is divided into a main viewing area 8 and a left and right side viewing area 9 , 10 . The main viewing area 7 depicts a field of vision used by the driver while driving in the direction of travel F, and the left and right side viewing area 9, 10 depicts a lateral field of vision when the head and/or body turn, in particular when the driver 6 looks to the side or shoulder . The main viewing area 8 is delimited by the A pillars 11 of the vehicle 1 and the two side viewing areas 9, 10 are delimited in the vehicle longitudinal direction F on the one hand by the A pillar 11 and on the other hand by a B pillar 12.

Depending on the current seat position of the driver's and front passenger's seat 2, 3, the front passenger's seat 3 or parts thereof such as the seat back 4 and/or the headrest 5 impair the right-hand side visibility area 10, as is shown in 1 is shown. The field of vision 10 blocked by the front passenger seat 3 creates a blind spot 13, which results in an enlarged blind spot when looking from the side or over the shoulder over the right shoulder. In order to obtain the maximum possible field of vision 7 to the outside, the driver 6 usually has to adjust the front passenger seat 3 independently, but this is probably done by the driver 6 in very few cases, since the front passenger seat 3 naturally does not impair the comfort of the driver 6 and the disadvantage of impaired vision is not consciously perceived. In many cases, this results in poor visibility from the vehicle 1 to the outside, which can essentially jeopardize traffic safety.

It is therefore an automatic seat adjustment of the front passenger seat 3 from a position of use S1 in a rest position S2, as in 2 shown, proposed, wherein the front passenger seat 3 is arranged in the rest position S2 outside of the active field of view 7 and the blind spot 13 is released or significantly reduced. Ideally, the front passenger seat 3, in particular the backrest 4 and/or the headrest 5, in the rest position S2 is brought into overlap with the B pillar 12 on the front passenger side or at least moved backwards until a maximum possible field of vision 7 to the outside is achieved. In particular, the rest position S2 refers to a current seat position of the driver's seat 2, which is only set if this is dependent on a seat occupancy of the front passenger seat 3 and a seat occupancy of a rear seat 14 on the passenger side, as in 4 shown, is permissible.

3 shows a schematic flow chart for a method 100 for automatic seat adjustment of the passenger seat 3, as in FIGS 1 and 2 described. In a first method step 101, a current seat position of the driver's seat 2 is detected. For this purpose, the current seat position of the driver's seat 2 can be detected, for example, via suitable sensors, such as sensors for detecting the travel path and/or end position sensors, etc., controlled by positioning times, based on a camera, or otherwise.

In a second and third method step 102, 103, a seat occupancy of the passenger seat 3 and the rear seat 14 on the passenger side is recorded and checked having to install sensors. Can an occupancy of the front passenger seat 3 and/or an occupancy of the rear seat 14 be answered with "yes" are answered, the automatic seat adjustment is aborted in a fourth method step 103 and no further action is taken. If an occupancy of the front passenger seat 3 and an occupancy of the rear seat 14 can each be answered with "no", in a fifth method step 105 a control signal for adjusting the front passenger seat 3 from the use position S1 to the rest position S2 is output.

In summary, a method is proposed in which the seat position of the driver's seat 2 is detected and the front passenger's seat 3 is adjusted to the rest position S2 depending on this when the front passenger's seat 3 and the rear seat 14 behind the front passenger's seat 3 are unoccupied.

In a further development of the method, a distinction can be made between a person and an object, preferably an infant carrier, on the passenger seat 3 as part of the second method step 102, with the passenger seat 3 being automatically adjusted to the rest position S2 when an infant carrier is detected on the passenger seat 3. when the rear seat 14 is unoccupied. For this purpose, suitable sensors must be used to determine that an infant carrier has been positioned on the front passenger seat 3 . For example, a camera, pressure or weight sensors, etc. would be suitable. Alternatively, an RFID sensor can also be used, in which case the infant carrier would have to be provided with a corresponding code.

In an alternative or optional additional development of the method, a distinction can be made in the third method step 103 between a person and an object, preferably an infant carrier or child seat, on the passenger-side rear seat 14, with the passenger seat 3 being detected on the detection of an infant carrier or child seat on the Rear seat 14 is automatically adjusted to a central rest position when the front passenger seat 3 is unoccupied or is not occupied by a person. Provision can optionally be made for the passenger seat 3 to be moved into a forward rest position when a person is detected on the rear seat 14 . Accordingly, the occupancy of the rear seat 14 is detected with a suitable sensor, as already described. In particular, the front and middle rest positions are defined as a sitting position of the front passenger seat 3 in which the foot space is released as much as possible and the seat back 4 and/or the headrest 5 are at least approximately, partially or completely overlapping with the B-pillar 12. A good compromise between the maximum possible field of vision 10 of the driver 6 and the available foot space between the front passenger seat 3 and the rear seat 14 is thus intended to be found through the front or middle rest position.

In an optional method step, not shown, the fifth method step 105 can be followed by a query which must be confirmed by the driver 6 so that the passenger seat 3 is moved to the rest position S2. For example, a message could be displayed in the central display or in the head-up display (HUD), which informs the driver 6 that the passenger seat 3 can be adjusted automatically. Based on the message, the driver 6 can then decide whether the front passenger seat should be adjusted or not, with the control signal being output if this is the case.

4 shows in a highly schematic representation an adjustment system 15 for the vehicle 1, which is used to carry out the method according to FIG 3 trained and/or suitable. The adjustment system 15 includes an adjustment device 16 for the electrical adjustment of the front passenger seat 3. The adjustment device 16 is designed to adjust a longitudinal position and/or height of the front passenger seat 3, an inclination of the seat backrest 4 and a height of the headrest 5 of the front passenger seat 3 individually or in combination adjust. For example, the adjustment device 16 is designed as an electromechanical actuator.

The adjustment system 15 also has a first detection device 17 for detecting a seat position of the driver's seat 2 and a second detection device 18 for detecting a seat occupancy of the front passenger seat 3 and the rear seat 14 . For this purpose, the first and the second detection device 17, 18 are designed as already described above.

Furthermore, the adjustment system 15 has a control device 19 which is set up to control the adjustment device 16 on the basis of the seat position of the driver's seat 2 and the seat occupancy of the front passenger and rear seats 3 , 14 . Ideally, an existing control unit (ECU) of the vehicle 1 can be used for electric seat adjustment, with the algorithm required for the automatic seat adjustment being implemented accordingly in the control unit. In particular, the control device 15 for carrying out the method according to FIG 3 educated. Provision is preferably made for all the hardware components required for the seat adjustment to be installed as standard in the vehicle 1 so that no additional hardware for the seat adjustment needs to be integrated in order to carry out the method or form the adjustment system 15 .

The control device 19 has an evaluation module 20, the first and the second Detection device 17, 18 are connected to the evaluation module 20 in terms of signals and/or data technology. Evaluation module 20 is designed to determine, evaluate and/or correlate a seat position of driver's seat 2 and a seat occupancy of front passenger seat 3 and rear seat 14 on the basis of the sensor data in order to issue a control command taking into account the current seat position of driver's seat 2 and the to generate current occupancy data of the passenger seat 3 and the rear seat 14 on the passenger side for a control module 21 . The control module 21 is designed to output an actuating signal for the adjusting device 16 on the basis of the control command, with the adjusting device 16 automatically adjusting the passenger seat 3 into the rest position S2 on the basis of the actuating signal, i.e. without direct triggering by the user/occupant. As a result, the field of vision 7 of the driver 6 is enlarged outwards from the vehicle 2 in order to obtain the best possible overview of the interior of the vehicle.

While at least one embodiment has been disclosed in detail above, it is to be appreciated that numerous variations of the invention exist. It should also be appreciated that the at least one embodiment is exemplary only and not limiting in scope, application, or configuration. Rather, the present disclosure is intended to be a convenient roadmap for implementing at least one embodiment. Thus, it should be appreciated that various variations in the function or arrangement of elements of the at least one embodiment can be implemented without departing from the scope as defined by the claims and their legal equivalents.
