A scenario (46) is initiated at the start of a movement of the vehicle door (20), during which the state of the functional element (10) changes from an initial state (42) via an intermediate state (48) to a final state (50). Furthermore, the invention also relates to a motor vehicle (2).

Description

[0001] The present invention relates to a method for operating a motor vehicle and a motor vehicle. The motor vehicle has doors and functional elements that are movably mounted between two end positions.

[0002] Motor vehicles, such as passenger cars, typically have multiple doors through which entry and exit into the vehicle's interior space are possible. In this case, it is known to assign microswitches to the doors, which are triggered when the doors are closed. When the door is opened, the microswitches activate, thereby turning on the interior lighting. Therefore, the interior space is visible to a user entering the vehicle from the outside, facilitating seating. For example, any obstacles on the seats can also be identified. Furthermore, the edges of the door openings are also illuminated, aiding in getting in and out of the vehicle.

[0003] However, if, for example, the door is only briefly opened a relatively small gap, such as to remove clothing caught between the door and the edge, the overall lighting will also be turned on, which may cause discomfort to passengers inside the vehicle due to the glare effect.

[0004] If a vehicle is in a relatively confined environment, the doors may not be able to open fully. In this situation, the user cannot perceive how much adjustment range the door has from its final position. Therefore, it is possible, for example, for the user to wait until the vehicle has moved out of the confined space (e.g., automatically or by the driver) before getting in. If the door can only be adjusted to a relatively small extent at this point, getting in / out of the vehicle from its previous position is also feasible and does not significantly reduce comfort. However, the user cannot anticipate this. This increases the operational burden and reduces comfort.

[0005] The object of the present invention is to provide a method particularly suitable for operating a motor vehicle and a motor vehicle particularly suitable therefor, wherein comfort is suitably improved.

[0006] According to the invention, with respect to the method, this objective is achieved by the features of claim 1, and with respect to motor vehicles, by the features of claim 12. Advantageous improvements and designs are the subject of the respective dependent claims.

[0007] This method is used to operate motor vehicles. The motor vehicles are suitably secured to the land and are preferably designed for multiple lanes. In this case, it is feasible, for example, to position the motor vehicles substantially freely, particularly on the road. For this purpose, the motor vehicles conveniently have corresponding wheels. In short, preferably, the motor vehicles can be positioned substantially independently of other conditions on the land. In other words, the motor vehicles are suitably not track-guided. Preferably, the motor vehicles are passenger cars or commercial vehicles, such as trucks or buses.

[0008] The motor vehicle has a door that is movably mounted between two end positions. Specifically, in this case, the door is attached to the body of the motor vehicle, and the door corresponds to an opening in the body. Because it is movably mounted, it is feasible to both cover and open the opening with the door. In one of these end positions, the opening is suitably covered by the door and thus completely closed. In the other end position, the door is arranged such that the opening is suitably opened to the maximum extent, making it feasible to enter the interior space of the motor vehicle through the opening.

[0009] Specifically, the door is mounted on the vehicle body. Hinges are used for movable mounting, allowing the door to be pivotally mounted. Alternatively, the mounting element is designed as a slide rail, allowing the door to slide on the vehicle body. For example, a motor is assigned to the door, which drives the door. Therefore, it is possible, for example, for the door to pivot automatically by means of the motor, or for the door to be manually adjusted with the assistance of the motor. The door is, for example, a side door of a motor vehicle, such as a driver's door, a passenger door, or a rear door. Alternatively, the door is, for example, a trunk lid or hood.

[0010] Motor vehicles also include functional elements that can have different states. In this case, the user is particularly able to perceive the current state of the functional element.

[0011] In this method, a scene is initiated when the movement of the car door begins. In other words, the movement of the car door is monitored, and the scene is initiated accordingly. Suitablely, the scene ends once the movement of the car door stops or ends. For example, if the car door can only be adjusted by a possible electric motor, the scene is initiated, for example, once the motor is powered on. Alternatively, the scene is initiated, for example, once a request to operate the electric motor is received. If a motor exists but manual adjustment is also possible, a speed sensor corresponding to the motor is specifically used to determine the movement of the car door. This sensor is specifically designed in the style of a Hall sensor. However, if the car door can only be adjusted manually, the current position of the car door is specifically determined by a corresponding sensor, such as an accelerometer and / or a gyroscope.

[0012] In this scenario, the state of the functional element is changed, i.e., from an initial state, which is the state the functional element possesses, specifically at the start of the scenario and / or before the scenario begins. Then, during the scenario, the initial state transitions to a final state via intermediate states. Therefore, the functional element can have at least three different states. Here, the initial state, intermediate states, and final states are, for example, always the same, or particularly preferably depend on the current environment and / or situation. These states also preferably depend on the direction of movement of the door between its final positions. Therefore, for example, it is feasible to use the initial state used during the door opening movement as the final state of the scenario during the closing movement.

[0013] Therefore, in this method, a scene is initiated each time the door begins to move. Thus, if the door stops after partially opening and then continues to open, the scene is initiated again, where the initial state, intermediate state, and / or termination state are appropriately adapted to the door position at the time of the renewed movement.

[0014] Based on this method, users can always identify when the door moves. Therefore, the unexpected initiation of door movement also appropriately leads to changes in the state of functional components, which users can relatively easily identify. Thus, for example, it prevents the door from unexpectedly moving towards objects. Therefore, safety and / or comfort are improved. Furthermore, because sudden switching of functional component states is avoided through changes in intermediate states, motor vehicle users, for example, will not be startled by changes unrelated to door movement. Therefore, comfort is improved.

[0015] For example, a functional element may have only three different states. However, it is particularly preferred that the functional element includes multiple states. These states are, for example, discontinuously designed, or preferably involve a substantially continuous change of state from an initial state through intermediate states to a final state, thereby improving the user experience. Particularly preferably, during a scenario, the current state of the functional element is selected based on the current position of the door. Thus, in particular, each position of the door along the adjustment path formed between two terminal positions explicitly corresponds to a state of the functional element. Therefore, the user, for example, can determine the current position of the door based on the state of the functional element.

[0016] Particularly preferably, the change of state ends when the door stops. For example, the scene also ends thereafter, so that the scene is only implemented during the movement of the door. Once the door stops, the current state of the functional element is suitably used as the termination state. Therefore, the termination state is not known at the start of the door movement, but is specifically predetermined based on the position the door has at the end of the movement. Thus, the user can always know the current position of the door based on the state of the functional element. If the door moves again after it stops, for example, along the original direction of movement, the state continues to change, particularly towards the direction of the original termination state. Conversely, if the door moves in the opposite direction to the original direction of movement, the state also suitably changes, but preferably towards the direction of the previous initial state, which is used as the new termination state, for example.

[0017] Therefore, alternatively or particularly preferably in combination with this, a termination state is used when the door reaches one of the terminal positions. Specifically, the scene ends when the door reaches one of the terminal positions. In summary, the termination state suitably corresponds to one of the terminal positions. Here, in particular, the scene is executed whenever the door moves. Therefore, when the functional element has a termination state, the user can perceive that the door has reached a terminal position, even if the user can only partially see the door. This further improves user comfort.

[0018] For example, state changes are always performed in the same way. In other words, the state changes at the same speed. However, it is particularly preferable to determine the speed of the door and perform state changes according to that speed. In other words, the speed of state change is selected based on the speed of the door's movement. Therefore, suitably, the speed of the execution scene is also set according to the speed of the door. It is particularly preferable that the termination state is reached when the door reaches the terminal position.

[0019] Therefore, if the door adjustment is relatively slow, the state changes relatively slowly as well. Thus, the user can also identify the speed of the door adjustment based on the rate of change in the state of the functional components. For example, if the motor operates slowly, for example because of an obstruction in the door's adjustment area, the user can be aware of this. To determine the door speed, an acceleration sensor corresponding to the door is specifically used. Alternatively, or in combination with this, a gyroscope or Hall sensor corresponding to a possible motor is employed. In another alternative, the door speed is determined, for example, based on the operating data of a possible motor, particularly based on the current conducted by the motor.

[0020] Alternatively or particularly preferably in combination with this, the intermediate state time point is selected based on the position of the door, i.e., the time point when the functional element has an intermediate state. Preferably, this time point is selected between the time point at which the movement begins and the time point at which the door may reach its final position. For example, the intermediate state time point is selected midway between these two time points. This ensures that there are sufficiently long time periods between the initial state and the intermediate state, and between the final state and the intermediate state, so that the state of the functional element does not need to be changed too quickly.

[0021] For example, a speaker is used as a functional element, and the state is specifically the output of tone or tone sequence. In this case, the initial state, intermediate state, and final state specifically correspond to different tone sequences or different tones. Alternatively or in combination with this, volume is used as the state. In this case, the same tone or the same tone sequence is always output during the scene, or different states correspond to different tones / tone sequences. Thus, the user can determine the current position of the car door by sound.

[0022] Alternatively or in combination with this, interior lighting fixtures are preferably used as functional elements. These interior lighting fixtures are suitably used to illuminate the interior space of the motor vehicle. Specifically, the interior lighting fixtures include one or more overhead lights, and / or luminaires corresponding to the dashboard / doors. In an improved embodiment, the functional element also corresponds to exterior lighting, which suitably includes headlights and / or projectors.

[0023] For example, brightness is used as a state. Here, for example, at least during the opening movement of the door, a brightness of 10% is used as the initial state, 50% as the intermediate state, and 100% as the final state. If the door is closed, the brightness is appropriately reduced accordingly, so that 100% is used as the initial state, 50% as the intermediate state, and 0% or 10% as the final state. Suitablely, different positions of the door each correspond to a state, and therefore also to a brightness. In particular, the brightness is continuously changed during the movement of the door. Thus, the user can perceive the degree of door opening based on the brightness. If the door is opened to its maximum extent, the interior space lighting device appropriately reaches its maximum brightness, thereby facilitating getting in and out of the vehicle. Suitablely, once the movement of the door is interrupted, i.e., the door stops, the state change also ends. Therefore, the current brightness of the interior space lighting device is maintained. When the door moves again, the brightness is specifically changed accordingly, starting from the current brightness (which then corresponds to the initial state). Therefore, based on changes in brightness, users can perceive subtle movements of the car door, while avoiding excessive brightness changes that might cause discomfort, thus improving comfort. Alternatively, or in combination with this, light color can be used as a state. For example, green or purple can be used as the initial state, red as an intermediate state, and blue as the final state. This allows for clear identification of the current position of the car door.

[0024] In another alternative, a window glass is used as a functional element, specifically corresponding to a car door. The transparency of the window glass is used as a state. In other words, the transparency of the window glass is variable, and the window glass is specifically designed as so-called "smart glass." Preferably, in this case, when the car door is closed, a completely transparent window glass corresponds to the initial state, and a completely opaque window glass corresponds to the final state. Conversely, when the car door is open, a completely opaque window glass is used as the initial state, and a transparent window glass as the final state. Therefore, when the car door is closed, it obstructs the view of unauthorized peeking into the interior of the vehicle. Conversely, when the car door is open, it allows observation through the window glass, facilitating entry and exit from the vehicle.

[0025] In another alternative, a seat is used as a functional element, and its position is used as the state. The seat is specifically adjustable via an electric motor. Suitablely, the entire seat can be adjusted longitudinally and / or vertically. Alternatively or in combination, the seat position is determined based on the recline of its backrest and / or the height of its headrest. Appropriately, at least when the door is closed, the position corresponding to the user is used as the final state, and the current position of the seat as the initial state. If the door is open, the current position of the seat is used as the initial state, and a position facilitating entry and / or exit is used as the final state. A position corresponding to an intermediate state is always selected between the two. Therefore, the current degree of door opening can also be deduced from the current position of the seat.

[0026] As an alternative or particularly preferred combination, a fragrance device is used as a functional element. The fragrance device is specifically used here to provide and diffuse fragrance substances within the interior space of a motor vehicle. For example, the state is defined by the amount of fragrance substance released or, suitably, the mass of fragrance substance released (i.e., the release amount). If the release amount is 0 (zero), then in this case, the interior space is not scented. Suitably, this state corresponds here to a fully open door, specifically the initial state when the door is closed, and the final state when the door is open. Therefore, when it is possible to allow the fragrance substance to circulate out of the interior air, the fragrance device is not operated, thereby preventing the uncontrolled escape of the fragrance substance from the motor vehicle. This reduces operating costs.

[0027] The motor vehicle is suitably a land-traveling vehicle, such as a commercial vehicle like a truck or bus. However, the motor vehicle is particularly preferably a passenger car. The motor vehicle has doors and functional elements movably mounted between two end positions. The motor vehicle is operated according to a method in which a scenario is initiated when movement of the door begins, during which the state of the functional elements changes from an initial state through intermediate states to a terminated state. Suitably, the scenario ends once movement of the door ends, for example, because the door has reached one of the end positions or because the door stops prematurely.

[0028] Suitablely, the motor vehicle has control devices configured and adapted to perform the method. The control devices include, for example, dedicated circuitry (ASIC), or particularly preferably, a computer suitably configured to be programmable. Specifically, the control devices include a storage medium storing thereon a computer program product, also known as a computer program, wherein when the computer program product (i.e., the program) is executed, it causes the computer to perform the method.

[0029] The present invention also relates to a control device. This control device is configured and adapted to perform the method. The control device includes, for example, a dedicated circuit (ASIC) and / or a microprocessor, by means of which the method is at least partially performed. In particular, the control device includes a computer program product stored in a memory, and when the program is executed by a computer, such as a microprocessor, the computer causes it to perform the method. Preferably, the control device in its assembled state is a component of a motor vehicle and is suitable, particularly configured and adapted, for this purpose. For example, the control device is constructed by means of a door control device or, particularly preferably, by means of an onboard computer of the motor vehicle. In another alternative, the control device corresponds to a functional element and is signal-technically connected to another control device corresponding to a door. In particular, in this case, the other control device triggers / controls door movement or at least detects door movement. To achieve the signal-technical connection, a bus system of the motor vehicle, particularly a CAN bus system, is used.

[0030] The present invention also relates to such a computer program product. This computer program product includes a plurality of instructions that, when a computer executes a program (computer program product), cause the computer to perform the method. The computer is suitably a component of, and for example constituted by, a control device of a motor vehicle or an electronic device. The computer preferably includes or is formed of a microprocessor. For example, the computer program product is a file or data carrier containing an executable program that, when installed on a computer, automatically performs the method.

[0031] The present invention also relates to a storage medium for storing computer program products. Such a storage medium is, for example, a CD-ROM, DVD, or Blu-ray disc. Alternatively, the storage medium is a USB stick or other memory, which is, for example, rewritable or write-once. Such memory is, for example, flash memory, RAM, or ROM.

[0032] The advantages and improvements mentioned in this method are also applicable to motor vehicles, control equipment, computer program products, storage media, and each other, and vice versa.

[0033] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Wherein:

[0034] Figure 1 A motor vehicle is schematically shown, comprising a door movably mounted between two end positions and a plurality of functional elements; and

[0035] Figure 2 A method for operating a motor vehicle is shown.

[0036] In all figures, the corresponding parts use the same reference numerals.

[0037] Figure 1 A simplified schematic representation of a motor vehicle 2 in the form of a passenger car is shown. The motor vehicle 2 has multiple wheels 4, which are positioned on the road in their prescribed use condition. These wheels 4 are movably mounted on a body 6 via a chassis, which encloses an interior space 8. The interior space 8 is provided with multiple functional elements 10, one of which is an interior lighting device 12 comprising multiple overhead lights. Another such functional element 10 is a seat 14 arranged within the interior space 8, which can be adjusted via an electric motor using an adjustment drive device (not shown in detail), thereby allowing its position to be changed. Another functional element 10 is a fragrance device 16, by which fragrance substances are released into the interior space 8.

[0038] The interior space 8 is accessible via an opening 18 in the body 6, which is covered by a door. The door 20 is pivotally mounted to the body 6 via a hinge 22. Therefore, the door 20 is movably mounted between two end positions 24, with an adjustment path 26 predetermined by the hinge 22 extending between these two end positions. When the door 10 is in one of the end positions 24, the opening 18 is completely covered, and the door 20 is closed. In the other end position 24, the opening 18 is maximally open, and the door 20 is open.

[0039] The door 20 is driven by an electric motor (not shown in detail). When the motor is energized, the door 20 moves along an adjustment path 26. Depending on the direction of the motor's energization, the door 20 moves in different directions along the adjustment path 26, i.e., opening or closing. A Hall sensor corresponds to the motor, which measures the motor's rotational speed. This speed is used to adjust the motor to a specific target speed, thereby causing the door 20 to move along the adjustment path 36 at a desired adjustment speed.

[0040] The operation of the electric motor is, for example, based on an adjustment request provided by an onboard computer (not shown in detail). Alternatively or in combination with this, the operation is based on user input devices (such as door handles) (not shown in detail).

[0041] The door 20 is also equipped with a window 28, which can be opened and closed by means of an electric lifter (not shown in detail) of the door 20. The window 28 is designed as "smart glass," so its transparency can be changed. Therefore, the window 28 also constitutes a functional element in the functional element 10.

[0042] In summary, the motor vehicle 2 has a door 20 that is movably mounted between two terminal positions 24 and a plurality of functional elements 10, wherein an interior space lighting device 12 is used as one of the functional elements 10, a window glass 28 is used as another functional element, a seat 14 is used as yet another functional element, and an aromatherapy device 16 is used as yet another functional element.

[0043] The motor vehicle 2 also includes a control device 30, which includes a computer 32 in the form of a programmable microprocessor. Furthermore, the control device 30 has a memory 34 on which a computer program product 36 is stored. The computer program product 36 has a plurality of instructions that, when executed by the computer 32, cause the computer to perform certain actions. Figure 2 The method 38 for operating the motor vehicle 2 is shown. Therefore, the control device 30 is configured and adapted to execute method 38 and operate the motor vehicle 2 according to method 38. The control device 30 is designed here, for example, as a door control device, and by means of this control device, for example, an electric lift and / or an electric motor (not shown in detail). In other words, the control device 30 is therefore used for opening and closing the doors 20 and the windows 28. Furthermore, the control device 30 is connected to the onboard computer of the motor vehicle 2 via a bus system (not shown in detail).

[0044] In method 38, the start of movement of the door 20 is determined in the first working step 40. It is also determined here whether the movement of the door 20 is performed manually or based on the operation of an electric motor (not shown in detail). Furthermore, the speed of the door 20's movement is determined. To determine the movement and speed, for example, a motor speed sensor, such as a Hall sensor, is used, where the motor speed is a function of the door 20's adjustment speed due to mechanical coupling with the door 20. Alternatively or in combination with this, the door 20 itself is equipped with an acceleration sensor, by which the speed of the door 20 can be directly measured.

[0045] Furthermore, an initial state 42 is determined for each functional element 10. This initial state corresponds to the current state of the corresponding functional element 10. For the interior space lighting device 12, brightness and color temperature are used as the state, and the initial state 42 corresponds to the current brightness and color temperature. In other words, the state of the interior space lighting device 12 is determined based on brightness and color temperature. For the seat 14, its position is used as the state, and the current position of the seat 14 is used as the initial state 42. For the window glass 28, its transparency is used as the state, and the initial state 42 corresponds to the current transparency. For the fragrance device 16, its release level is used as the state, and the initial state 42 of the fragrance device 16 corresponds to the current state when the fragrance device diffuses fragrance into the interior space 8. In an improved embodiment, a speaker (not shown in detail) is also used as a functional element 10, and the state corresponds to the set volume, by which sound is output by the speaker.

[0046] In the subsequent second working step 44, scene 46 is activated. Therefore, scene 46 is activated when the movement of the door 20 begins. For scene 46, corresponding intermediate states 48 and termination states 50 are set for each functional element 10. These states depend on the direction of movement of the door 20. If the door 20 is closed, for the interior space lighting device 12, a blue light color and 10% brightness are used as termination state 50. For the seat 14, the position corresponding to the user is used as termination state 50. A 100% one-time release is used as termination state 50 for the fragrance device 16. For the window glass 28, complete opacity is used as termination state 50.

[0047] For each functional element in functional element 10, the corresponding intermediate state 48 is always set at an intermediate position between the corresponding initial state 42 and the corresponding final state 50. If the initial state 42 of the window glass 28 is completely transparent, then the intermediate state 48 is 50% transparency. If the initial state 42 of the interior space lighting device 12 is 100% brightness, then the intermediate state 48 is 55% brightness. The color is also adjusted appropriately.

[0048] Conversely, when the door 20 is opened, the final state 50 of the interior lighting device 12 uses 100% brightness and a purple hue. The final state 50 of the seat 16 is chosen to facilitate getting in and out of the vehicle; for the fragrance device 16, the final state 50 has zero emission; and for the window glass 28, the final state 50 is completely transparent. Here, the intermediate state 48 is also selected as the middle position between the corresponding initial state 42 and the corresponding final state 50.

[0049] The time point for each intermediate state 48 is selected based on the initial position of the door 20, the terminal position 24 in the direction of movement (i.e., the maximum length the door 20 can move along the adjustment path 26), and the speed of the door 20. Here, the time point is selected such that the intermediate state 48 is reached midway between the start of the movement and the arrival at the terminal position 24. Therefore, if the door 20 moves at a constant speed, the time interval between the start of the movement and the intermediate state 48 is equal to the time interval between the intermediate state 48 and the expected arrival at the terminal position 24. Thus, the length of the time interval and the time point of the intermediate state 48 are selected based on the position of the door 20.

[0050] Furthermore, based on the determined speed of the door 20, the rate of change of state for each functional element 10 is determined. This rate of change is constant and chosen such that when the corresponding state changes at the corresponding rate of change, once the door 20 reaches the corresponding terminal position 20, each functional element 10 moves from the corresponding initial state 42 to the corresponding terminal state 50. In this case, the corresponding intermediate state 48 is also reached at an assumed time point in the intermediate state 48. In summary, for each functional element 10, the rate of change of state is determined based on the speed of movement of the door 20, the corresponding initial state 42, and the corresponding terminal state 50.

[0051] In the subsequent third working step 52, the state of each functional element 10 is changed, i.e., according to the assumptions made in the second working step 44. Here, a rate of change determined for each functional element 10 is used, which may differ between the individual functional elements 10. Therefore, in each functional element 10, the state changes from the corresponding initial state 42 via an intermediate state 48 to the corresponding final state 50.

[0052] If the door 20 moves at a constant speed, it reaches an intermediate state 48 at the assumed time point, and when the door 20 reaches the corresponding terminal position 24, each functional element in the functional element 10 has its own corresponding termination state 50. Therefore, when the door 20 reaches one of the terminal positions 24, the corresponding termination state 50 is used. Then, scene 46 and method 38 end.

[0053] During scenario 46, the speed of door 20 is continuously monitored. When the speed changes, the speed of state change is also adjusted, so that even when the speed of door 20 changes, each functional element 10 uses termination state 50 when door 20 reaches the corresponding terminal position 24.

[0054] If door 20 stops before reaching the corresponding terminal position 24, the state change also ends and scenario 46 is terminated. Furthermore, method 38 ends. When door 20 moves again, method 38 is restarted, using the state achieved by each functional element 10 at that time as the corresponding initial state 42. Additionally, the corresponding termination state 50 is selected based on the direction of door 20's movement.

[0055] This invention is not limited to the embodiments described above. Rather, those skilled in the art can derive other variations of the invention without departing from its subject matter. Furthermore, in particular, all the individual features described in connection with the embodiments can be combined with each other in other ways without departing from the subject matter of the invention.
