Description

[0001] The invention relates to a method for operating a door system of a motor vehicle and to a door system for a motor vehicle. The door system comprises several electrically driven doors, which are assigned to different body openings.

[0002] Motor vehicles, such as passenger cars, typically have several doors, each covering a specific opening in the vehicle body. By adjusting the doors, it is possible to open the respective opening, allowing a user or other person to enter and exit the vehicle. To prevent unauthorized access, each door is usually equipped with a lock.

[0003] To increase convenience, it is known to operate the locks electrically. The system also monitors the user's approach to the vehicle from the outside, and when the user is sufficiently close, the locks unlock. Thus, no manual action is required by the user to unlock the vehicle. To further enhance convenience, it is also known to design the doors with electrical motors. This allows the respective door to pivot relative to the vehicle body by operating the electric motors, again eliminating the need for manual action. The electric motors are activated, for example, by operating an input device such as a door handle or a switch attached to the door handle.

[0004] While most of the steps involved in opening the door when the user approaches the vehicle are automated, some manual intervention is still required. For example, if the user is carrying a relatively large and / or unwieldy object, it is necessary to place the object next to the vehicle before the user can enter.

[0005] The invention is based on the objective of providing a particularly suitable method for operating a door system of a motor vehicle and a particularly suitable door system for a motor vehicle, wherein comfort and / or user acceptance are expediently increased, and wherein manufacturing costs are preferably reduced.

[0006] With regard to the method, this problem is solved according to the invention by the features of claim 1, and with regard to the door system by the features of claim 10. Advantageous further developments and embodiments are the subject of the respective dependent claims.

[0007] The method serves to operate a door system. The door system is suitable, and in particular designed and configured, to be mounted on a motor vehicle or at least to form a component of the motor vehicle in its assembled state. The motor vehicle is suitably land-based and preferably multi-track. It is suitably possible to position the motor vehicle essentially freely, particularly on a roadway. For this purpose, the motor vehicle expediently has appropriate wheels. In summary, it is preferably possible to position the motor vehicle on land essentially independently of other conditions. In other words, the motor vehicle is suitably not rail-guided. Preferably, the motor vehicle is a passenger car or a commercial vehicle, such as a truck or bus.

[0008] The door system has several doors that are electrically driven. Each door is assigned its own electric motor.

[0009] For example, the respective electric motor is designed as a brushed commutator motor. However, it is particularly preferred that it be brushless and expediently a brushless DC motor (BLDC). For example, the electric motors assigned to the different doors may differ, or they may preferably be identical. Thus, identical parts can be used. Expediently, each electric motor and its associated door are components of a respective motorized door adjustment mechanism. Preferably, the respective motorized door adjustment mechanism includes a gearbox and / or a variable-length component, such as a spindle, which are mechanically arranged between the electric motor and the door. In particular, the gearbox is designed as a worm gear drive. For example, the gearboxes may differ, or they may preferably be identical.At least each door and its associated electric motor are mechanically coupled, so that when the electric motor is operated the door is moved, i.e. adjusted.

[0010] In particular, each door has a bearing by means of which the door is movably, i.e., adjustable, mounted to other components of the motor vehicle when installed. For example, at least one of the doors is designed as a pivoting side door. Alternatively or in combination with this, at least one of the doors is designed as a sliding door. In particular, at least some of the doors are assigned to different sides of the motor vehicle and, in particular, form side doors. For example, at least some of the doors are identical in construction. Alternatively, they are different from each other. Preferably, at least two of them are mirror images of each other. Suitablely, one of the doors is a driver's door and / or one of the doors is a passenger door. Advantageously, at least one, preferably two, of the doors is a rear door. Preferably, the door system has a total of four doors, which are advantageously each side door.Conveniently, a door is also provided, which can be used to form a tailgate. Alternatively, or in combination, one of the doors can be used to form a front hatch.

[0011] Preferably, each of the doors has a door body, by means of which, for example, at least part of the outer skin of the motor vehicle is formed. A door module or the like is arranged on the outer skin, and is covered on the inside by an interior panel. A window regulator, preferably an electric motor, is preferably connected to the door module.

[0012] The doors are assigned to different body openings. In other words, the vehicle body has body openings, each corresponding to one of the doors. These body openings are conveniently separated from each other and therefore do not merge. For example, the body openings and / or the parts surrounding them, such as a specific body section, may be part of the door system or separate from it. At a minimum, each door is assigned to one of the body openings. It is convenient that the operation of the respective electric motor allows the door to be moved relative to the body opening, so that the openings are either open or closed.

[0013] Advantageously, a seat is positioned near each body opening, allowing access to the corresponding seat through that opening. The seats may be, for example, an integral part of the door system or separate from it. The door system also includes several interior lights, with one assigned to each door. These are, for example, mounted on the headliner in the vehicle's interior, allowing them to be used as reading lights. Ideally, the interior lights are positioned above their respective seats. Alternatively, at least one of the interior lights may be integrated into the seat or another component of the vehicle. At a minimum, the interior lights are located within the vehicle and thus protected by the bodywork.For example, the interior lighting can be the same or different for different doors. For instance, the interior lighting can be used to create a specific, focused beam of light or something similar. It can also be used to create different colored light using all or at least one of the interior lights, or the interior lighting can be used to provide only monochromatic light.

[0014] The method involves recording user behavior. For example, the user might be inside the vehicle. However, it is particularly preferred that the user be outside the vehicle. The user's behavior is recorded using a suitably designed sensor, such as a camera, radar sensor, capacitive sensor, or radio module.

[0015] Based on user behavior, an assumption is made regarding a user request to adjust one of the doors. For example, to create this assumption, it is checked whether the behavior corresponds to a specific pattern, which might be statically stored. Alternatively, an artificial intelligence algorithm, such as a neural network, can be used to create the assumption based on the behavior. The user request specifies, in particular, which door should be adjusted and, for example, whether the respective door should be closed or preferably opened. In summary, to create the assumption based on behavior, one door is selected from the available doors that is assumed the user wants adjusted, specifically opened. The assumption applies only to a single door or at least only to a subset of the doors.

[0016] The interior lighting assigned to this door is now being operated. In other words, the interior lighting associated with the door specified by the assumption is being activated. Due to this operation, the mode of operation has changed compared to before. For example, the interior lighting is now powered on, causing it to emit light. This light may be emitted continuously or intermittently, causing the interior lighting to flash. Alternatively, or in combination with this, the interior lighting may be operated in a specific color, emitting light with a specific wavelength. If the interior lighting was already emitting light previously, it will now be emitted differently, for example, with a different color or at a different interval length / continuously.Due to the operation of the interior lighting, the user can see which door was selected by way of the acceptance process.

[0017] The user reacts specifically to the operation of the interior lighting and adjusts their behavior accordingly, thus recording a reaction. Based on this reaction, the user either confirms or rejects the lighting. In a subsequent step, the user's reaction is recorded. Depending on the reaction, the door is then adjusted, for which the electric motor is appropriately powered. Ideally, the door is opened during this process.

[0018] Due to the system's design, the user can see which door has been selected based on their behavior before the door is adjusted. If the user's request does not match the system's designation, the user can adjust their response accordingly, preventing the selected door from being adjusted. Conversely, if the correct door has been selected, and the system's designation matches the user's request, the user can confirm this through their response, resulting in the door being adjusted. Thus, the user does not need to manually operate the door system, yet only the door corresponding to their request is adjusted. In other words, the desired door is adjusted precisely, with the door system first providing feedback to the user. Subsequently, the user provides feedback to the door system.This increases user comfort and user acceptance of the door system.

[0019] No additional components are required, or at least it is possible to use the interior lighting for other functions as well. Therefore, manufacturing costs are not increased. Since the interior lighting is used for feedback, there are no restrictions, or only specific requirements, such as legal regulations concerning pedestrian protection or traffic flow / permitted signaling devices. Furthermore, the user can clearly identify which door has been selected based on the respective interior lighting.

[0020] For example, the process is essentially carried out continuously. However, it is particularly preferred that it is started when the vehicle is stationary and the approach of the user is detected. The approach is detected, for example, by a camera or a suitably designed sensor. In particular, the approach of a portable object, such as a key fob, a smartphone, a smartwatch, or another wearable device, is detected to register the user's approach. Preferably, depending on the approach of the portable object, any existing locking system is also activated, so that, in particular, the doors are unlocked.

[0021] For example, user behavior is determined based on a gesture or similar indicator. However, a user trajectory is particularly preferred as the indicator of behavior. In other words, the direction and / or speed of the user's movement is checked. Consequently, the user does not need to perform and remember a specific gesture or similar action, which increases convenience. The assumption is conveniently made simply based on the user's approach to the vehicle.

[0022] For example, a specific probability of impact at a particular location is generated based on the trajectory, with each location assigned to one of the doors. An artificial intelligence algorithm, such as a neural network, is used for this purpose. However, a threshold comparison is preferred. This reduces the computational effort and allows the process to be implemented with relatively limited hardware resources. In this approach, different thresholds are assigned to the doors, which are defined, for example, based on the user's current position. The angle at which the user impacts the vehicle is compared to these thresholds. Alternatively, or in combination with this, the user's distance from each door as they continue along the trajectory and reach the vehicle is compared.In this process, the speed is also taken into account, and at a comparatively high speed, for example, a more distant door is used.

[0023] For example, the user's reaction is determined based on a gesture or similar, or preferably based on a further trajectory. This further trajectory follows the initial trajectory and begins, in particular, as soon as the interior lighting is activated. If, subsequently, the user's direction of movement and / or speed changes significantly, this is appropriately interpreted as indicating that the assumption does not correspond to the user's wishes, i.e., that the user rejects the assumption. Conversely, if the further trajectory essentially corresponds to the initial trajectory, i.e., if the direction and / or speed are essentially maintained initially, this is taken as confirmation that the assumption corresponds to the user's wishes, i.e., that the user confirms the assumption.For example, to determine whether the user confirms or rejects the acceptance, an “artificial intelligence” algorithm, such as a neural network, is used, or a threshold comparison is preferably carried out.

[0024] The trajectory is appropriately used as the behavior, and the subsequent trajectory as the reaction. This allows the same sensors to be used for both, thus reducing manufacturing costs. For example, the trajectory and / or the subsequent trajectory are captured using a camera. Alternatively, the respective trajectory is preferably determined based on any portable object carried by the user, such as a key fob and / or a smartphone. This is comparatively resource-efficient and reduces the effort required.

[0025] For example, the interior lighting continues to operate in the same manner after the user's response and / or switches off after a predetermined period. However, the operation of the selected door is particularly preferred, depending on the response. If the response corresponds to a confirmation of the user's request, this is indicated, for example, by a different flashing interval or continuous operation of the interior lighting. Alternatively, a different color might be used. This ensures the user understands that their response has been correctly registered. It also alerts the user that the door will be adjusted accordingly, preventing any surprises.If, however, the response indicates that the adjustment does not meet the user's request, the interior lighting is appropriately operated in a different manner. This makes it clear to the user that the door will not be adjusted. Preferably, the operation of the interior lighting is changed again during the door adjustment, and preferably a different color is used. If, for example, the response is mistakenly interpreted as confirmation that the adjustment meets the user's request, the user is also informed that the door is now being adjusted, even though this is incorrect.

[0026] For example, the door is adjusted solely based on the response. Specifically, the door is adjusted if the response indicates that the current setting corresponds to the user's request, and the adjustment is omitted if the response indicates that the current setting deviates from the user's request. In this case, the process is terminated. Preferably, however, the initial setting for the user's request is then created again, this time selecting a different door. This (new) setting is preferably created based on the response. In other words, the initial setting for the user's request to adjust a different door is created based on the response. Therefore, if the initial setting was incorrect, a different door is selected, eliminating the need for manual input.The interior lighting associated with the other door is then preferably activated, and the user's reaction is recorded. If the user's subsequent reaction indicates that the (new) door corresponds to the user's request, the other door is created. Preferably, the creation of the door, the activation of the associated interior lighting, and the recording of the respective user reactions are carried out until the reaction indicates that the door corresponds to the user's request. Then, the last selected door is adjusted.

[0027] For example, the interior lighting is activated as soon as the booking is initiated. However, it is particularly preferred that the occupancy status of any seat assigned to this door is first determined. Depending on the occupancy status, the interior lighting assigned to this door is then activated. If the seat is unoccupied, the interior lighting is activated. If, on the other hand, the seat is occupied, i.e., if a person is already sitting there, the interior lighting is expediently deactivated. Consequently, the operation of this interior lighting is preferably suppressed, or the booking for this door is prevented altogether. At the very least, the door assigned to this seat is not moved. Consequently, the person sitting in the seat is not disturbed by the approach of the user. Furthermore, it is ensured that the person is not injured by the subsequent movement of the door.Furthermore, it is prevented, for example, that the person can exit the vehicle as long as the user remains at a distance from it. Thus, if the person is a child or someone requiring assistance, it is ensured that they cannot exit the vehicle unsupervised.

[0028] Alternatively, or preferably in combination, a child safety setting is determined. This setting allows for separate adjustment of each door, specifically determining whether that door can be opened from the inside. The child safety setting is conveniently activated when the seat associated with that door is used exclusively, primarily, and / or currently for transporting a child. In particular, the interior lighting associated with that door is controlled by the child safety setting, as has been assumed. If the child safety setting is active, the operation of the interior lighting is suppressed, and preferably, the door opening is also prevented. This ensures that a child in the seat cannot leave the vehicle unattended.For example, this is always done, or, more appropriately, it is also checked whether there is a person in the interior or at least on the seat and / or an adjacent seat. If these are unoccupied, the interior light is still switched on, and the door may also be adjusted if necessary, based on the assumption and the response. This allows entry, especially for a child, if, for example, the child is accompanied by the user. The user does not need to let go of the child's hand to open the door, which increases safety.

[0029] For example, if multiple users or other individuals are registered, a corresponding entry is created for each one. Specifically, this ensures that a number of doors are opened that correspond to the number of users present. Alternatively, for instance, only one user can be selected, and an entry created for them. However, the preferred approach is to stop creating the entry altogether when multiple users are registered. This prevents excessive overhead and avoids misinterpreting behavior and potential reactions.

[0030] The door system is suitable for a motor vehicle and, in its installed state, is a component of the motor vehicle. The motor vehicle is, for example, a commercial vehicle such as a truck or bus. Preferably, however, the motor vehicle is a passenger car. The door system comprises several electrically driven doors, each assigned to a different body opening. In particular, each door has a corresponding bearing by which it is mounted to the body, allowing each door to be adjusted relative to its assigned body opening. Each door has an interior light, which is also a component of the door system. The interior lights are located inside the motor vehicle. The door system operates according to a method that detects user behavior. Based on this behavior, an assumption is made regarding a user's request to adjust one of the doors.The interior lighting associated with this door is then activated, and a user response is detected. Depending on this response, the door is adjusted. For example, the adjustment speed might be chosen based on the response, or, more appropriately, the decision might be made whether or not to adjust the door at all.

[0031] The door system includes, in particular, a control unit designed and configured to carry out the method. The control unit comprises, for example, an application-specific integrated circuit (ASIC) or, more preferably, a computer, which is suitably programmable. In particular, the control unit includes a storage medium on which a computer program, also referred to as a computer program, is stored, and the execution of this computer program causes the computer to carry out the method. Advantageously, the door system, or at least the vehicle, includes a sensor that can detect the user's approach to the vehicle and / or its trajectory.

[0032] The interior lighting is, for example, either an integral part of an assigned seat or at least partially integrated into the headliner. It is possible, for instance, to change the color of the light provided by the interior lighting. Alternatively, or in combination with this, it is possible, for example, to create a directed beam of light using any of the interior lights, or at least a part of them, the extent and / or direction of which can be changed.

[0033] The invention further relates to such a motor vehicle. The invention further relates to a computer program product. The computer program product comprises a number of commands which, when executed by a computer, cause the computer to perform a method for operating a door system of a motor vehicle with several electrically driven doors assigned to different body openings. In the method, user behavior is detected. Based on this behavior, an assumption is made regarding a user request to adjust one of the doors. The interior lighting assigned to this door is activated, and a user response is detected. Depending on the response, the door is adjusted. The computer is expediently a component of a control unit or electronics of the door system and is, for example, formed by means of such a unit.The computer preferably comprises a microprocessor or is formed by means of one. The computer program product is, for example, a file or a data carrier containing an executable program that, when installed on a computer, automatically executes the procedure.

[0034] The invention further relates to a storage medium on which the computer program product is stored. Such a storage medium is, for example, a CD-ROM, a DVD, or a Blu-ray Disc. Alternatively, the storage medium is a USB flash drive or other storage medium that is, for example, rewritable or write-only. Such storage medium is, for example, flash memory, RAM, or ROM.

[0035] The invention further relates to a control unit. The control unit is designed and configured to carry out a method for operating a door system of a motor vehicle with several electrically driven doors assigned to different body openings. In this method, user behavior is detected. Based on this behavior, an assumption is made regarding a user request to adjust one of the doors. The interior lighting assigned to this door is activated, and a user response is detected. Depending on this response, the door is adjusted. The control unit includes, for example, an application-specific integrated circuit (ASIC) and / or a microprocessor, by means of which the method is at least partially carried out.In particular, the control unit comprises a computer program stored in memory, which, when executed by a computer such as a microprocessor, causes the computer to carry out the procedure. Preferably, the control unit is an integral part of the door system in its installed state and is specifically designed and configured for this purpose. For example, the control unit is a door control unit. For instance, the control unit also controls an electric window regulator integrated into one of the doors. The electric window regulator preferably comprises another electric motor that drives the window pane.

[0036] The advantages and further training mentioned in connection with the procedure can also be applied analogously to the door system / the motor vehicle / the computer program product / the storage medium / the control unit, as well as to each other and vice versa.

[0037] An embodiment of the invention is explained in more detail below with reference to a drawing. The drawing shows: Fig. 1 Schematic side view of a motor vehicle comprising a door system with several electrically driven doors, Fig. 2 a method for operating the door system, and Fig. Figures 3-8 schematically depict the motor vehicle from a bird's-eye view in different states during the execution of the procedure.

[0038] Corresponding parts are marked with the same reference symbols in all figures.

[0039] In Fig. Figure 1 schematically simplifies the representation of a motor vehicle 2 in the form of a passenger car (PKW). The motor vehicle 2 has several wheels 4 that rest on the ground and are connected to a body 6 by means of a chassis (not shown in detail).

[0040] The body 6 has several body openings 8, which are separated from each other. Each of the body openings 8 is assigned a door 10, which is movably mounted on the body 6 by means of a bearing 12, such as a hinge. It is possible to open or close the respective body opening 8 by adjusting each door 10. In the example shown, the doors 10 are side doors and are pivotally mounted on the body 6.

[0041] Each of the doors 10 has its own electric motor 14, which is mechanically connected to its respective door 10 via a worm gear transmission (not shown). Thus, the doors are electrically driven. The electric motors 14 are designed as brushed direct current (BLDC) motors and, together with their respective transmissions and the doors 10, form at least a partial electric door drive. When the electric motor 14 is operated, the respective door 10 is adjusted relative to the vehicle body 6.

[0042] Each of the doors 10, and thus each of the body openings 8, is assigned a seat 16, which can be accessed via the corresponding body opening 8. In other words, entry and exit are possible via each body opening 8, allowing a person to reach the respective seat 16. An interior light 18, which can serve as a reading light, is located above each seat 16. It is possible to create different colored lights using the interior lights 18 and / or to operate them continuously or flashing. In a variant not shown in detail, it is possible to create a cone of light using the interior lights 18, and / or the interior lights 18 are at least partially integrated into the respective assigned seat 16.

[0043] The electric motors 14, the doors 10, the interior lights 18, and, where applicable, the body openings 8 and / or the seats 16 form a component of a door system 20 of the motor vehicle 2. The door system 20 also includes a control unit 22, which comprises a computer 24 in the form of a microprocessor. Furthermore, the control unit 22 has a memory 26 on which a computer program 28 is stored. The computer program 28 comprises several instructions which, when executed by the computer 24, cause it to perform a function in Fig. 2. The door system 20 is operated according to the procedure 30 shown in section 2, and the control unit 22 is designed and configured to carry out the procedure 30.

[0044] In the first step 32, an approximation of a Fig. The user 34 is detected in a bird's-eye view. For this purpose, a portable object carried by the user 34, such as a key fob, is detected by means of a sensor (not shown) and its distance and direction of movement relative to the vehicle 2 are recorded, defining a trajectory 36 of the user 34. If the user 34 falls below a minimum distance to the vehicle 2, a locking system (not shown) is activated and the doors 10 are unlocked. If several users 34 are detected, the procedure 30 is then terminated. Otherwise, a second step 38 is carried out.

[0045] In the second step 38, a behavior 40 of user 34 is recorded, for which trajectory 36 is used. In other words, user 34's trajectory 36 is used as behavior 40. Based on behavior 40, an assumption 42 is created. Assumption 42 concerns a user request, i.e., a request from user 34, to adjust one of the doors 10. It is assumed that user 34 wants to enter the interior of the vehicle 2 through this door 10. In summary, assumption 42 for the user request to adjust one of the doors 10 is created based on the behavior.

[0046] To create assumption 42, the trajectory 36 is compared with several threshold values. If the speed is above one of the threshold values, it is assumed that the user 34 is walking past the vehicle 2, and the procedure 30 is terminated. Otherwise, the position of the trajectory 36 and the direction of movement are further checked. In the example shown, the user 34 approaches the vehicle 2 from the right side. It also appears that the user 34 will encounter the vehicle 2 between the two doors 10. Since the doors 10 are pivotally mounted on the body 6, entry through the front of the two doors 10 is only possible at such a position. The threshold values ​​are chosen such that, as assumption 42 for the user's request, the front right door 10 is selected.

[0047] If further users 34 are recorded during the second work step 38 or any other work step of the procedure 30, the creation of the acceptance 40 and also the procedure 30 are terminated. In other words, if multiple users 34 are recorded, the creation of the acceptance 40 is terminated.

[0048] Once assumption 42 has been created, a third step 44 is performed. In this step, it is first checked whether seat 16, which is assigned to the door 10 specified by assumption 42, is occupied. In other words, the movement state of seat 16 assigned to this door 10 is determined. If this is the case, procedure 30 is either terminated, or the second step 38 is performed again, with assumption 42 now being created for a different door 10.

[0049] Furthermore, in the third step 44, a child safety setting is determined for the door 10 specified by assumption 42, i.e., whether this door 10 can be opened from the inside, for example. If the child safety setting is active, the second step 38 is also carried out again, whereby assumption 42 is now created for a different door 10.

[0050] If seat 16 is neither occupied nor the child safety lock is active, the interior light 18 assigned to this door 10 is operated as described in Fig. Figure 4 illustrates this. The interior lighting 18 will continuously emit light. This allows the user 34 to see which of the doors 10 has been specified by assumption 42. In the example shown, the front right door 10 has been selected. Therefore, if this seat 16 is occupied or the child safety lock is active, the interior lighting 18 will not be activated. In other words, the interior lighting 18 is activated depending on the occupancy status of the assigned seat 16 and the child safety lock setting. If the child safety lock setting is active, but there is no one in seat 16 or, for example, in the other seats 16, the interior lighting 18 will still be activated.

[0051] In a subsequent fourth step 46, a reaction 48 of the user 34 is recorded. This reaction 48 is based on a further trajectory 50 of the user 34. This further trajectory 50 begins where trajectory 36 ends, and it ends as soon as the interior lighting 18 is activated. In the example shown, the user 34 slightly changes their direction of movement towards the front right door 10, which thus represents reaction 48. In this case, reaction 48 confirms that assumption 42 corresponds to the actual user request.

[0052] Consequently, a fifth work step 52 is carried out. In this step, the operation of the interior lighting 18 is changed, and it is now controlled to flash, so that pulsating light is emitted. After a short period of time, the electric motor 14 assigned to this door 10 is then energized, so that the door 10 is adjusted, namely opened, as in Fig. Figure 5 is shown. During the adjustment of the door 10, the operation of the interior lighting 18 is changed again, so that the user 34 is alerted to the ongoing adjustment of the door 10.

[0053] If, however, user 34's response 48 differs, the second step 38 is performed again. In other words, the second step 38 is performed if response 48 indicates that assumption 42 does not meet the user's request. Fig. Figure 6 shows a corresponding reaction 48. In this case, the subsequent trajectory 50 deviates considerably from trajectory 36, which is determined by a threshold comparison. In this case, the interior lighting 18 is no longer operated. In summary, the interior lighting 18 is operated depending on reaction 48.

[0054] If the second step 38 is performed again, the subsequent trajectory 50 is now used as trajectory 36, based on which assumption 42 is created again, this time concerning a different door 16. Consequently, depending on the response 48, assumption 42 is created for the user's request to adjust a different door 10. In the example shown, the user 34 moves to the rear of the two right-hand doors 10, which is now selected using assumption 42.

[0055] In the third work step 44, which is then carried out again, the interior lighting 18 assigned to the other door 10 is operated, as in Fig. Figure 7 shows that, based on the subsequent trajectory 50, the user's reaction 48 34 is recorded in the fourth work step 46. Depending on this reaction 48, the interior lighting 18 assigned to the other door 10 is also operated, and the corresponding door 10 is adjusted if necessary, as shown in Figure 7. Fig. 8 shown.

[0056] The invention is not limited to the embodiment described above.
