Description

[0001] The invention relates to a method for adjusting a motor vehicle seat. In this method, an actuation action on an actuation element of the motor vehicle is detected by means of a detection device. Furthermore, the seat position of the motor vehicle seat is adjusted by means of an adjustment device, depending on the actuation action.

[0002] It is known from the general state of the art to adjust seats in motor vehicles manually, for example by means of a rotary knob on one side of the seat, or automatically by pressing one or more buttons on the seat.

[0003] Automatic seat adjustments when switching from manual to automatic driving mode are also known from the prior art. For example, US 2021 / 0053590A1 describes an automatic driving control device for a vehicle. This device stores position information for a seat in which the driver is seated in manual driving mode. It also stores the seat position changed by the driver while driving in automatic mode. When the driving mode changes from automatic to manual, the device automatically returns the seat to a position corresponding to the stored position information from the manual driving mode.

[0004] Furthermore, EP 3 521 107 A1 describes a method for saving a seat position in a manual or automatic driving mode. This method checks whether a switch for adjusting a seat position is being operated. Simultaneously, it checks which driving mode the vehicle is in. If the vehicle is in an automatic driving mode, the set seat position is saved as the seat position for the automatic driving mode. If the vehicle is in a manual driving mode, the set seat position is saved as the seat position for the manual driving mode.

[0005] In US Regulation 2017 / 0334451A1, position information is also stored depending on the vehicle mode. In normal mode, the position information of the adjusted seat is stored as coordinates of the normal mode, and in automated driving mode, the position information of the adjusted seat is stored as additional coordinates of the automated mode.

[0006] German patent DE 10 2004 010 592 A1 describes a motor vehicle cockpit with a steering wheel and an adjustable seat. The seat can be adjusted via sensors located on the steering wheel. This involves moving the entire steering wheel, for example, by tilting it, to adjust the seat position. However, the seat can only be adjusted once a setting state has been selected, for example, by voice input. Until then, the seat is locked and cannot be adjusted. This document was used to formulate the preambles of the independent patent claims.

[0007] US Patent 2019 / 0071112A1 primarily concerns a steering wheel. An integrated touchscreen display is located in the center of the steering wheel. This central section serves not only as a primary information interface but also as the main graphical input interface for the user. Using the touchscreen, the user can access configured settings for various vehicle functions via setting parameters, which can be optionally displayed on the screen. For example, the driver's seat can be graphically represented for the "seat adjustment" function, with the backrest tilt adjustable via a corresponding touch gesture, which is also graphically displayed.

[0008] The disadvantage of such devices or methods is their particularly complex design. Furthermore, these devices or methods cannot guarantee that a driver in autonomous or automated driving mode, especially during highly automated driving, can resume the driving task at any time, thus compromising vehicle safety.

[0009] The object of the present invention is to provide an improved method for adjusting a seating position which is particularly easy and reliable to operate and at the same time ensures a particularly high level of driving safety.

[0010] This problem is solved by a method for adjusting a motor vehicle seat and by a motor vehicle with the features of the independent claims. Advantageous embodiments with expedient and non-trivial further developments of the invention are specified in the dependent claims.

[0011] According to the invention, this problem is solved by a method for adjusting a motor vehicle seat. The seat can be, for example, a driver's seat or a passenger's seat of the motor vehicle. In the method, an actuation action on an actuating element of the motor vehicle is detected by means of a detection device. The detection device is specifically designed to detect an actuation action on an actuating element. The actuation action or operating action can, for example, involve touching or exerting a pressure force on the actuating element, which is detected by the detection device. For example, a vehicle occupant sitting in the seat to be adjusted can actuate, operate, or touch the actuating element with a hand or a finger, which is then detected by the detection device.This offers the advantage that an actuation action on the actuating element can be recorded in a particularly simple and reliable manner.

[0012] In a further process step, the seating position of the vehicle seat is adjusted by means of an adjustment device, depending on the actuation action. In other words, the seating position can be adjusted accordingly, depending on how the actuation action is performed on the actuating element. "Adjusting the seating position" refers in particular to changing the coordinates of the seat from an initial position to another position and its associated coordinates. The seat can, for example, be moved linearly and / or rotated about an axis, especially the seat itself. Additionally or alternatively, the seat backrest can be moved, in particular pivoted, or tilted by a predetermined angle. Additionally or alternatively, the seat headrest can be adjusted or moved, in particular pivoted, or tilted by a predetermined angle.For example, the seat can be moved away from the steering wheel of the vehicle, particularly linearly, and the backrest can be swivelled backward, particularly away from the steering wheel, i.e., reclined. The operating element can accordingly also be referred to as a setup assistant. This allows a seat position to be set with a simple operation.

[0013] The method is characterized by the fact that the actuation action is detected at the actuating element located on the steering wheel of the motor vehicle. In other words, the actuation action can be detected at the steering wheel. For example, a vehicle occupant sitting in the seat to be adjusted can actuate or operate the actuating element on the steering wheel with their hand or a finger, for example, by pressing it. Alternatively, the actuation action can be detected at the actuating element located at a predetermined distance from the steering wheel, at a distance from which an occupant can operate the steering wheel to steer the vehicle. In other words, the actuation action can be detected close to the steering wheel.The actuating element can be arranged such that when the vehicle occupant, who is in the seat being adjusted, performs the actuating action on the actuating element, the vehicle occupant can still operate the steering wheel to drive the vehicle, i.e., steer it. For example, the actuating element can be arranged on the dashboard of the vehicle, particularly behind or next to the steering wheel. Preferably, the actuating element is arranged on the dashboard of the vehicle in such a way that the vehicle occupant, who is in the seat being adjusted, can operate the steering wheel with one hand and the actuating element on the dashboard with the other hand. This ensures that a vehicle occupant can continue to perform a driving task even when adjusting the seat by operating the actuating element.

[0014] In a further process step, a control unit of the motor vehicle activates the adjustment device for setting the seat position, depending on the actuation action, when the detection device registers the actuation action at the control element on the steering wheel or at a predetermined distance from the steering wheel. For example, the actuation element can comprise a key combination or a graphical user interface with multiple control panels, wherein one button or control panel can be used for linearly moving the seat and / or another button or control panel for rotating the seat and / or another button or control panel for adjusting the backrest and / or another button or control panel for adjusting the headrest. Preferably, the seat position is adjusted or moved as long as the actuation action at the control element is detected.This allows the seat to be moved into a comfortable position. The time it takes to adjust the seat position can also be called the travel time. It is particularly preferred that the operating element be activated throughout the entire travel time.

[0015] Furthermore, the control unit activates the adjustment mechanism to stop the seat position adjustment when the detection device registers that the operation, particularly depending on the seat position, is stopped at the operating element. For example, if the vehicle occupant, who is in the seat being adjusted, releases the operating element, especially on or next to the steering wheel, the seat adjustment, particularly the automatic seat adjustment, is terminated or stopped. If, for example, the vehicle occupant moves the seat away from the steering wheel while adjusting the seat position, the occupant can move the seat backward until their fingers no longer press or touch the operating element. As soon as the fingers, or even just one finger, no longer touch or press the operating element, the control unit can stop the seat adjustment, and the seat will no longer move.

[0016] In particular, the procedure determines which seat position is still suitable for the vehicle occupant to perform a driving task. To demonstrate that the vehicle occupant can perform the driving task, the actuation of the control element must be carried out. For example, the driver must operate the control element near or on the steering wheel for the entire duration of the test.

[0017] By positioning the control element on or near the steering wheel and requiring that it be continuously operated to adjust the seat position, it can be ensured that the vehicle occupant can continue to perform the driving task. This can increase safety while driving the vehicle.

[0018] According to a first alternative of the invention, a further operating action on a further means of driving the motor vehicle is detected by the detection device, wherein the further means of driving particularly comprises at least one pedal of the motor vehicle. The further means of driving can, for example, be a pedal of the motor vehicle, particularly preferably an accelerator pedal and / or a brake pedal and / or a clutch pedal of the motor vehicle. The detection device can be configured to detect an operating action, such as an actuation, in particular the exertion of a pressure force, on or to the pedal.Furthermore, the adjustment mechanism for setting the seat position is activated by the control unit depending on the actuation action, provided that the detection device simultaneously registers the other operating action on the vehicle's control unit. The seat position can therefore only be adjusted when the detection device registers or registers the actuation action on the control element and simultaneously or concurrently the other operating action on the control unit, in particular the pedal. For example, during the seat's travel time, the control element on or near the steering wheel and a vehicle pedal, such as the accelerator pedal, must be actuated or touched. In particular, the seat adjustment pedal may be in neutral or out of service, especially by the control unit.Furthermore, the adjustment mechanism for stopping the seat position adjustment is activated by the control unit when the detection system recognizes that further operation of the other vehicle component is being stopped. For example, if the vehicle occupant releases the pedal, the automatic seat adjustment is terminated. This provides an additional level of safety, ensuring that not only the steering wheel but also at least one other vehicle component, such as a pedal, can be operated during seat adjustment. This further enhances safety while driving the vehicle.

[0019] According to a second alternative according to the invention, the detection device comprises a camera directed towards the interior of the motor vehicle, wherein the camera monitors the position of the eyes of the vehicle occupant while the seat position is being adjusted. In particular, the camera is directed towards the head or eyes of the vehicle occupant. The control unit activates the adjustment device to stop the seat position adjustment when the camera detects that the vehicle occupant's field of vision lies outside the windshield or front window of the motor vehicle. The field of vision, which can also be referred to as the fixation field, refers in particular to an area that is fixed with the eyes.Alternatively, the camera can also detect the direction of gaze, stopping the seat adjustment as soon as the gaze shifts away from the vehicle's windshield. In other words, the camera specifically detects whether the vehicle occupant's eyes are looking through the windshield. For example, a seat can be adjusted as long as the field of vision or gaze direction is still directed at the windshield and the action of the adjustment mechanism is detected. The seat adjustment stops as soon as the vehicle occupant is no longer looking through the windshield. If the field of vision or gaze direction shifts to the dashboard, for example, due to the seat adjustment, the adjustment can be stopped.This incorporates an additional safety feature, namely that the vehicle occupant can still operate the steering wheel and that their view is directed at or through the windshield. This further increases safety while the vehicle is in motion.

[0020] An advantageous further development provides that an additional detection device is used to check whether the vehicle is in autonomous driving mode or stationary. Furthermore, the adjustment device for setting the seat position is preferably activated by the control unit as soon as the vehicle is in autonomous driving mode or stationary. For example, the seat adjustment can only be made either when the vehicle is stationary or during autonomous driving mode, and only as soon as the action on the control element is detected. "Autonomous driving mode" refers in particular to semi-autonomous or highly automated driving. If the vehicle is in manual driving mode, i.e., the vehicle occupant is driving, the seat adjustment cannot be performed.

[0021] An advantageous embodiment provides that the seat position, particularly the set position, is saved by means of a memory device as soon as the seat position adjustment is stopped. For example, the adjustment device or the control device is configured to transmit or transfer the current or set seat position to the memory device. Furthermore, the memory device can preferably be configured to assign the set seat position to a profile of a predetermined vehicle occupant, in particular the one who made the seat adjustment, and / or to save it in a profile of the predetermined vehicle occupant. For example, it can be provided that when switching from a manual driving mode to an autonomous driving mode, the saved seat position is restored, in particular automatically.This means that if, for example, a seat position was set and saved while stationary or in autonomous driving mode, the last saved seat position can be set when switching back to autonomous driving mode.

[0022] The invention also includes a motor vehicle. The motor vehicle comprises an adjustment device configured to set a seating position of the vehicle's seat. Furthermore, the motor vehicle comprises an actuating element configured to actuate the adjustment device. Preferably, the actuating element is configured as a button, a switch, or a GUI (Graphical User Interface), or the actuating element comprises several buttons or switches.

[0023] Furthermore, the motor vehicle has a detection device designed to detect an actuation action on the operating element. The actuation action can be detected, in particular, by a first detection element of the detection device, which is associated with or assigned to the operating element. The detection device can, for example, comprise a sensor, especially a capacitive sensor, or a camera to detect the actuation action. Thus, the first detection element can be designed as a sensor or a camera. The operating element is arranged on the steering wheel of the motor vehicle or at a predetermined distance from the steering wheel, at which a vehicle occupant can perform an actuation action on the steering wheel to drive the motor vehicle. Actuation action and operating action are, in particular, two different actions.The act of operation includes, in particular, the actuating or operating of the actuating element, and the act of operation includes the actuating or operating of a vehicle component for driving the motor vehicle, such as the steering wheel and / or one or more pedals of the motor vehicle. The act of operation specifically interferes with the driving process of the motor vehicle.

[0024] Finally, the motor vehicle has a control unit designed to activate the seat adjustment mechanism in response to an action performed by the sensor, when the sensor detects the action at the actuator on or at a predetermined distance from the steering wheel. For example, by operating the actuator, the control unit can activate the seat adjustment mechanism. The adjustment mechanism is specifically designed to automatically adjust the seat position. This automatic seat adjustment can also be referred to as automatic operation. For this purpose, the adjustment mechanism may, for example, include a motor or drive unit for automatically adjusting the seat position. Furthermore, the adjustment mechanism may include one or more actuators, particularly for adjusting the seat position.The corresponding actuators can then perform a linear movement of the seat and / or a rotation of the seat and / or an adjustment of the backrest and / or an adjustment of the headrest and / or an adjustment of other components of the seat, such as additional backrests and / or storage compartments and / or supports. The corresponding actuators can be operated by the motor or the drive unit.

[0025] Furthermore, the control unit is configured to activate the adjustment device to stop, halt, or terminate the adjustment of the seat position when the detection device registers that the actuation action on the actuator has been stopped. In particular, the detection device and / or the control unit and / or adjustment device are interconnected or coupled, especially via signaling. Specifically, the control unit is configured to receive an actuation signal upon detection of the actuation action and, in response to this signal, to output a control signal or command to the adjustment device.

[0026] According to a first alternative of the invention, the detection device is configured to detect a further operating action on another means of transport, wherein the further means of transport particularly comprises a pedal of the motor vehicle. Preferably, the detection device can have a second detection element which is assigned to or associated with the further means of transport for detecting the further operating action. For example, the detection device can have a sensor or a camera which is configured to detect the further operating action on the further means of transport. For example, the second detection element can be designed as a sensor or a camera. If the further means of transport is designed as a pedal, for example, the second detection element can be configured to detect, measure, or determine a pedal travel for detecting the further operating action.Furthermore, the control unit is configured to activate the adjustment mechanism for setting the seat position depending on the operating action, if the detection device simultaneously detects the other operating action on the vehicle's other means of operation. Additionally, the control unit is preferably configured to activate the adjustment mechanism to stop the seat position adjustment if the detection device detects that the other operating action on the other means of operation is being stopped. To detect the other operating action, for example, on the vehicle's pedals, the detection device can be configured to detect the pedal travel.

[0027] Advantageously, the detection device comprises a first detection element associated with the actuating element, wherein the first detection element is configured to detect the actuating action on the actuating element, and wherein the first actuating element is designed as a sensor or a camera. For example, the sensor can be designed as a capacitive sensor, a touch sensor, or a pressure force sensor. If the first detection element is designed as a camera, for example, the camera can be directed towards the interior of the vehicle. For example, the camera can be arranged on the vehicle's ceiling or headliner. Furthermore, the camera can preferably be directed towards the actuating element. With the aid of the first detection element, the actuating action can be detected particularly easily and reliably.

[0028] According to a second alternative of the invention, the detection device comprises a camera directed towards the interior of the motor vehicle. The camera is configured to monitor the position of the eyes of the vehicle occupant, who is seated in the seat being adjusted, when the seat position is being adjusted. The control device is configured to activate the adjustment device to stop the seat position adjustment if the camera detects that the occupant's field of vision lies outside the windshield of the motor vehicle. For example, the detection device may include a third detection element, which is configured as a camera. The camera is preferably arranged on the roof or headliner of the motor vehicle.

[0029] The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger car or truck, or as a passenger bus or motorcycle.

[0030] The control unit for the motor vehicle can include a data processing device or a processor unit configured to carry out an embodiment of the method according to the invention. For this purpose, the processor unit can include at least one microprocessor and / or at least one microcontroller and / or at least one FPGA (Field Programmable Gate Array) and / or at least one DSP (Digital Signal Processor). Furthermore, the processor unit can include program code configured to carry out the embodiment of the method according to the invention when executed by the processor unit. The program code can be stored in a data memory of the processor unit.

[0031] The invention also includes further developments of the motor vehicle and / or method according to the invention, which have features as already described in connection with the further developments of the method and / or motor vehicle according to the invention. For this reason, the corresponding further developments of the motor vehicle or method according to the invention are not described again here.

[0032] The invention also includes combinations of the features of the described embodiments. The invention therefore also includes realizations that each exhibit a combination of the features of several of the described embodiments, provided that the embodiments have not been described as mutually exclusive.

[0033] The following are exemplary embodiments of the invention described. This is illustrated by: Fig. 1. A schematic representation of a flowchart illustrating the procedural steps of the procedure for adjusting the seating position of a motor vehicle seat; and Fig. 2 a schematic representation of a motor vehicle with a driver's seat, a vehicle occupant who operates an actuating element for adjusting the seat position of the motor vehicle seat, a detection device and a control device.

[0034] The exemplary embodiments described below are preferred embodiments of the invention. In these exemplary embodiments, the described components each represent individual features of the invention, which can be considered independently of one another and each further develops the invention independently. Therefore, the disclosure is intended to include combinations of features of the embodiments other than those shown. Furthermore, the described embodiments can also be supplemented by further features of the invention already described.

[0035] In the figures, identical reference symbols denote functionally equivalent elements.

[0036] In the context of characters Fig. 1 and Fig. 2. The procedure for adjusting a motor vehicle seat will be discussed in more detail.

[0037] This shows Fig. 1. The procedure 10 for adjusting a motor vehicle seat in a flowchart, which illustrates the procedural steps of the procedure. Fig. Figure 2 shows a schematic perspective view of a motor vehicle 12 in which a passenger 14 is adjusting a seat 16. Passenger 14 is the driver of the motor vehicle 12. Seat 16 is the driver's seat. Passenger 14 can move the entire seat 16 linearly, as indicated by arrow 18. Passenger 14 can move the seat 16 towards or away from the steering wheel 20 of the motor vehicle 12. Furthermore, passenger 14 can rotate the seat 16 about an axis, as indicated by arrow 22. Furthermore, the vehicle occupant 14 can adjust a backrest 24 of the seat 16, in particular tilt it at a predetermined angle α or tilt it forwards and backwards, as indicated by the arrow 26.Furthermore, the vehicle occupant 14 can adjust a headrest 28 of the seat 16. The occupant 14 can tilt the headrest 28 at a predetermined angle β or tilt it forwards and backwards, as indicated by arrow 30. Other seat adjustments are also possible, such as tilting a seat cushion and / or adjusting a shoulder support of the seat 16, or adjusting other backrests and / or supports and / or storage compartments of the seat 16. "Adjusting the seat position" means, in particular, that the seat is moved from one seating position, especially the initial seating position, to another. The respective seating position is specifically linked to coordinates. In particular, a seating position in an initial position is adapted to a manual driving mode of the motor vehicle 12.This means that in the initial position, the vehicle occupant 14 is seated on seat 16 or the seat position is adjusted so that the vehicle occupant 14 can perform a driving task, in particular drive the motor vehicle 12.

[0038] To adjust the seating position of the seat 16, an actuating action must be performed or carried out on an actuating element 32', 32".

[0039] For example, the actuation action can be performed by the vehicle occupant 14. The vehicle occupant can operate or control the actuating element 32', 32" with their hand 34 or a finger 36 of hand 34, or perform an actuation action. For example, the vehicle occupant 14 can press the actuating element 32', 32" with their finger 36. The actuating element 32', 32" can, for example, be designed as a button. The actuating action is then detected by a detection device. The detection device has a first detection element 38, which is assigned to or associated with the actuating element 32', 32". The first detection element 38 is configured to detect the actuating action at the actuating element 32', 32". In other words, the first detection element 38 can detect the actuation, in particular directly, at the actuating element 32', 32"

[0040] Depending on the actuation of the actuating element 32', 32" or the actuation action of the actuating element 32', 32", a seating position of the seat 16 can be set. For this purpose, the actuating element 32', 32" can, for example, have a key combination. The actuating element 32', 32" can, for example, have a key for linear movement, as indicated by arrow 18, and / or a key for rotation of the seat 16, as indicated by arrow 22, and / or a key for tilting the seat back 24 of the seat 16, as indicated by arrow 26, and / or a key for tilting the headrest 28 of the seat 16, as indicated by arrow 30. Alternatively, the actuating element 32', 32" can also be designed as a graphical user interface, which allows, in particular, the desired seating position to be set.

[0041] By performing an actuation action on the actuating element 32', 32", an adjustment device 40 for adjusting the seat position of the seat 16 of the motor vehicle 12 is actuated. The adjustment device 40 is specifically coupled or connected to the seat. The first detection element 38, which detects the actuation action on the actuating element 32', 32", can output a detection signal to a control unit 42, which then controls or activates the adjustment device 40 for adjusting the seat position, particularly depending on the actuation action. Specifically, the detection device or the first detection element 38 is coupled or connected to the control unit 42, particularly via signal transmission. Specifically, the control unit 42 can output adjustment commands to the adjustment device 40 for adjusting the seat position, depending on the actuation action.For this purpose, the adjustment device 40 can, for example, include a motor or drive unit for automatically adjusting or changing the seat position. Furthermore, the adjustment device 40 can include one or more actuators, particularly for adjusting the seat position. The corresponding actuators can then perform a linear displacement of the seat 16 and / or a rotation of the seat 16 and / or an adjustment of the backrest 24 and / or an adjustment of the headrest 28 and / or an adjustment of other components of the seat 16, such as additional backrests and / or storage compartments and / or supports.

[0042] In a first procedural step S1, the actuation action on the actuating element 32', 32" of the motor vehicle 12 is recorded in the procedure for adjusting the seat position of the seat 16.

[0043] However, in order to ensure safety during the journey of the motor vehicle 12, the procedure for adjusting the seat position includes one or more testing or safety stages.

[0044] In process step S1, the actuation action on the actuating element 32', 32" is also recorded. This element is located on the steering wheel 20 or at a predetermined distance from the steering wheel 20, at which point an operating action on the steering wheel 20 of the motor vehicle 12 for driving the motor vehicle 12 by the vehicle occupant 14 can be performed. The actuating element 32', 32" is therefore arranged either on the steering wheel 20 or near the steering wheel 20. The actuating element on the steering wheel is designated with the reference numeral 32' and the actuating element near the steering wheel is designated with the reference numeral 32". If the actuating element 32" is arranged near the steering wheel, it is positioned relative to the steering wheel 20 in such a way that the vehicle occupant 14 can still perform an operating action on the steering wheel 20.If the actuating element 32" is arranged near the steering wheel, it is arranged in such a way to the steering wheel 20 that the vehicle occupant 14 can, for example, operate the steering wheel 20 with one hand and the actuating element 32" with the other hand.

[0045] If, during process step S1, it is detected that the actuation action on the actuating element 32', 32" is performed on or near the steering wheel 20, then in process step S5 the control unit 42 activates the adjustment device 40 to adjust the seat position of the seat 16. If, however, during process step S1 it is detected that the actuation action on the actuating element 32', 32" is stopped, then in process step S6 the control unit 42 activates the adjustment device 40 to stop the seat position adjustment. The seat 16 is thus adjusted as long as the actuation action on the actuating element 32', 32" is detected.Alternatively, if, during process step S1, the detection device or the first detection element 38 detects that no actuation action is being performed on the actuating element 32', 32", then in process step S6 the control unit 42 activates the adjustment device 40 to stop the seat position adjustment. In this case, the control unit 42 is configured to activate the adjustment device 40 and prevent the seat position adjustment. In other words, if it is determined that the actuating element 32', 32" is not being actuated at all, the seat position adjustment cannot even begin.

[0046] Additionally or alternatively, the procedure 10 may include a further test step or safety level for adjusting the seating position of the seat 16. For this purpose, the detection device has a second detection element 44, which is configured to detect a further operating action on another means of operation 46 for driving the motor vehicle 12. The other means of operation 46 is, for example, a pedal, in particular an accelerator pedal, a brake pedal, or a clutch pedal of the motor vehicle 12. The further operating action may, for example, involve touching and / or exerting a pressure force on the means of operation 46. The second detection element 44 may, for example, be configured to detect pedal travel in order to detect the further operating action on the pedal.If, in process step S1, the actuation action on the actuating element 32', 32" on or near the steering wheel 20 was detected by the first detection element 38, in a further process step S2 it is checked whether, simultaneously with the actuation action, the subsequent operating action on the further vehicle 46 was detected by the second detection element 44. This can be done, for example, by the control unit 42. If the subsequent operating action on the further vehicle 46 was detected simultaneously by the second detection element 44, the control unit 42, in process step S5, controls the adjustment device 40 for adjusting the seat position of the seat 16, depending on the actuation action on the actuating element 32', 32".If the second detection element 44 subsequently detects that the further operating action has been stopped, or if the first detection element 38 detects that the actuation action has been stopped, then in process step S6 the adjustment device 40 is activated by the control unit 42 to stop the adjustment of the seat position. If, in process step S2, no further operating action on the additional means of transport 46 for driving the motor vehicle 12 is detected during the actuation action on the actuation element 32', 32", then the seat position of the seat 16 is not adjusted, as is particularly clarified by process step S6.

[0047] Additionally or alternatively, the procedure 10 may include a further test step or a further safety level for adjusting the seating position of the seat 16. For this purpose, the detection device includes a camera 48. In particular, the detection device may include a third detection element, which is designed as a camera. The camera 48 is directed towards an interior 50 of the motor vehicle 12. For this purpose, the camera 48 is arranged on the ceiling of the motor vehicle 12 or on the headliner of the motor vehicle 12. The camera 48 is configured to detect the field of vision 52 of the vehicle occupant 14 or the position of the eyes 54 of the vehicle occupant 14. In a procedure step S3, the camera 48 monitors the position of the eyes 54 of the vehicle occupant 14. The camera 48 checks whether the field of vision 52 of the eyes 54 of the vehicle occupant 14 lies outside or inside a windshield 56 of the motor vehicle 12.If the field of vision 52 is directed towards the windshield 56, the control unit 42 activates the adjustment device 40 to adjust the seat position of the seat 16 in process step S5. However, if the field of vision 52 lies within the windshield 56, process step S1 and / or process step S2 must first be completed. That is, if the field of vision 52 is directed towards or through the windshield and, in particular, if the actuation action on the actuating element 32', 32" has been detected simultaneously, and in particular if the further operating action on the additional vehicle component 46 has also been detected, then the seat 16 can be adjusted. To adjust the seat 16, process step S1 and process step S3 alone may also be required.If, during the adjustment of the seat 16, the additional detection device 18 detects that the field of vision 52 of the eyes 54 of the vehicle occupant 14 leaves the windshield 56, i.e., lies outside the windshield 56, then the control unit 42, in process step S6, activates the adjustment device 14 to stop the adjustment of the seat position. Conversely, if it is detected that, for example, the field of vision 52 was not directed at the windshield 56 from the outset, then the seat 16 cannot be adjusted.

[0048] Additionally or alternatively, the procedure 10 may include a further test step or safety level for adjusting the seat position of the seat 16. For this purpose, the motor vehicle 12 may have a further detection device 58. In particular, the further detection device 58 is preferably coupled or connected to the control unit by means of a signal. In procedure step S4, the further detection device 58 checks or detects the driving mode of the motor vehicle 12. If the motor vehicle 12 is in an autonomous driving mode or is stationary, the control unit 42 activates the adjustment device 40 to adjust the seat position in procedure step S5. If the motor vehicle 12 is in a manual driving mode, the adjustment device does not adjust the seat position.However, if the motor vehicle 12 is stationary or in an autonomous driving mode, process steps S1 and / or S2 and / or S3 must first be completed. That is, if the motor vehicle 12 is, for example, in autonomous or fully automatic driving mode and, in particular, the actuation action on the actuating element 32', 32" has been detected, and in particular, the further operating action on the additional vehicle component 46 has also been detected, and in particular, the field of vision is within the windshield 56, then the seat 16 can be adjusted. If, during the adjustment of the seat 16 in process step S6, the driving mode changes from a stationary or autonomous driving mode to a manual driving mode, the control unit 42, in process step S6, activates the adjustment device 40 to stop the adjustment of the seat position.To adjust seat 16, only procedure step S1 and procedure step S4, or procedure step S1, S2 and S4, or procedure step S1, S3 and S4 can be fulfilled.

[0049] If the seat has been adjusted accordingly in procedure step S5, preferably according to the specifications of the vehicle occupant 14, the adjustment can be completed in the following procedure step S6, for example by ending the actuation at the actuating element 32', 32".

[0050] Was the corresponding action performed in Fig. If the action is recorded in the respective procedural step, this is indicated in particular by a checkmark. If the corresponding action was not recorded in the respective procedural step, this is indicated in particular by a cross.

[0051] Overall, the examples show how a driver's seat adjustment with a monitoring function for measuring the driver's ability to take over can be provided.

[0052] The seat can be moved to a comfort position, particularly during autonomous driving of the vehicle, preferably during a suitable Level 3 function, by means of an automatic cycle. A prerequisite for adjusting the seat is, in particular, that the driver can still reach the steering wheel and / or pedals. It is necessary to determine, in effect, which seat position is still suitable for the driver to perform the driving task. For verification purposes, the driver must operate a control element on or near the steering wheel and / or pedals for the entire duration of the seat's movement. If the driver releases the control element, which is designed, in particular, as a push button, the automatic seat cycle, i.e., the adjustment of the seat or seat position, is terminated.

[0053] It is also conceivable, additionally or alternatively, to allow the driver to adjust the seat while the vehicle is stationary and / or to save the individually determined seat position or setting in order to use it while driving, especially during automatic or autonomous driving, and / or to save the seat position or setting in a personalization profile.

[0054] Additionally or alternatively, the driving position can be saved so that it is automatically restored when the comfort seat position is no longer selected. Additionally, a control element can initiate the automatic adjustment of the seat via a specific movement profile, particularly in a coordinated manner, using the various seat actuators. Additionally or alternatively, the control element, which is designed in particular as a button, capacitive sensor, or similar device, can be operated by the driver to continue adjusting the seat. As the seat is adjusted, the driver's body moves further away from the steering wheel and pedals. If the control element is no longer activated, which can be detected in particular by a sensor, the seat configuration is preferably locked and / or saved.
