Description

The invention relates to a method for operating a system of a motor vehicle, having a first door having a first electric motor door adjustment, and having a second door having a second electric motor door adjustment. The invention further relates to a system of a motor vehicle.

Motor vehicles have to increase the comfort of electromotive door adjustments. In this case, a door, such as a tailgate or a side door, is pivoted by means of an electric motor upon activation. The electric motor is operatively connected to the door by means of a worm gear or the like, so that the door is either opened or closed as a function of the rotational movement of the electric motor. The activation of the electric motor of the electric motor door adjustment is usually carried out by means of a switch which is arranged on the door, for example within a handle of the door. Usually, after activation of the respective electromotive door adjustment, the energization of the electric motor essentially takes place immediately, so that it is substantially clear to the user that the command for activating the electric motor has been detected correctly. The electric motor itself is usually designed brushless or brushed and is regulated by means of a regulation to a certain speed, so that the door is moved at a predetermined speed. Here, for example, a substantially constant speed is given, which increases a sense of quality for the user of the motor vehicle.

If, for example, the motor vehicle has been exposed to sunlight for a relatively long time and is in a comparatively warm environment, it is possible that an interior of the motor vehicle is heated comparatively strong. Thus, it is possible that the temperature in the interior of the motor vehicle exceeds 50 ° C. To remedy this, usually all or at least a majority of the doors are opened by a user of the motor vehicle, so that the warm air of the interior can escape from the motor vehicle. Even if a comparatively extensive charging activity is performed, usually all or at least a majority of the doors of the motor vehicle are opened, which facilitates loading. In both cases it is necessary to close the doors again before starting the journey. For this purpose, it is necessary that the driver of the motor vehicle moves to each door and operates there the respective switch for activating the electric motor for pivoting the respective door in the closed state.

The invention has for its object to provide a particularly suitable method for operating a system of a motor vehicle and a particularly suitable system of a motor vehicle, wherein advantageously reduces a burden of a vehicle electrical system and in particular comfort is increased.

With regard to the method, this object is achieved by the features of claim 1 and in terms of the system by the features of claim 11 according to the invention. Advantageous developments and refinements are the subject of the respective subclaims.

The method is used to operate a system of a motor vehicle, which is for example a passenger car. The system has a first electromotive door adjustment with a first door. Here, an electric motor of the electric motor door adjustment is in operative connection with the first door. In particular, a transmission, such as a worm gear, is driven by means of the electric motor, which is in operative connection with the first door by means of further components of the electromotive door adjustment, for example by means of a spindle or by means of a cable pull. The first door itself preferably has a receiving point for a fitting or the fitting itself, by means of which the door is articulated to a body of the motor vehicle. For example, the Fitting a hinge so that the first door is pivoted relative to the body. The first door here is in particular a side door or a trunk lid. Alternatively, the fitting is a running track, so that the first door is designed according to a sliding door. The Verstellpfad the first door is thus either substantially rectilinear or curved.

Depending on the direction of rotation of the electric motor of the first electromotive door adjustment, the first door is moved in one of two adjustment directions, so that the first door is moved from an at least partially closed position to an at least partially open position and thus an opening movement is performed. In the other direction of rotation of the electric motor, the first door is moved from the at least partially open position to an at least partially closed position and thus carried out a closing movement. The electric motor is designed, for example, brushless and electrically contacted by means of an inverter with a vehicle electrical system of the motor vehicle. The inverter is a component of a control device, by means of which the rotational speed and direction of rotation of the electric motor is adjusted.

Furthermore, the system has a second electromotive door adjustment, which comprises a second door. The second door is driven by means of an electric motor of the second electromotive door adjustment, in particular via a gear, such as a worm gear, which is in operative connection with the second door and the electric motor of the second electric motor door adjustment. The second door expediently has a fitting or a receiving point for a fitting for connection to the body of the motor vehicle, such as a hinge or a running fitting, so that the second door can be pivoted or moved with respect to the body. Preferably, the electric motor of the second electromotive door adjustment is identical to the electric motor of the first electromotive door adjustment. In particular, the second electromotive door adjustment is identical to the first electromotive door adjustment or at least similar to this configured. For example, the second electromotive door adjustment is mirror-symmetrical to the first electric motorized door adjustment. Suitably, the first is electromotive Door adjustment of one side of the motor vehicle and the second electromotive door adjustment of the second side of the motor vehicle is assigned. Alternatively, one of the two electromotive door adjustments of a second or third row of seats of the motor vehicle is assigned, and the remaining electromotive door adjustment is associated with a first row of seats. In a further alternative, the door is one of the two electromotive door adjustments of the boot lid, whereas the door of the other electromotive door adjustment is a side door, which is articulated, for example, pivotally or slidably on the body of the motor vehicle.

Preferably, the first and / or second electromotive door adjustment comprises a closing mechanism, by means of which the respective door is brought into a locked or at least latched state. In this case, an additional force is applied to the door, in particular by means of a selection of a further gear stage or by means of a further electric motor, so that a counterforce applied with a possible seal is overcome.

Appropriately, the system has further electromotive door adjustments, which is for example identical to the first or second electromotive door adjustment or at least symmetrical to one of the two electromotive door adjustments. Conveniently, the system comprises a total of four or five electric motor door adjustments, the motor vehicle expediently has a total of four side doors, which are each driven by means of an electric motor of the respective associated electric motor door adjustment. In particular, the driver's door and the passenger's door are driven by means of the electric motor. Also any two rear doors are suitably each a part of one of the electromotive door adjustments, the rear doors are pivoted or moved by means of the respective associated electric motor, for example. Preferably, the system comprises the fifth electric motorized door adjustment, the door of which is suitably the boot lid of the motor vehicle.

The method provides that in a first step, a request for carrying out a closing movement of the first door and for carrying out a closing movement of the second door is detected. Thus, the request includes a command to move the first door to the closed position. Further, the request includes the command to move the second door to the closed position. If the system also comprises further electromotive door adjustments, the request also has, for example, the commands to perform a closing movement with these electromotive door adjustments. By means of the closing movement, the first door and the second door are to be brought into a closed position, so that they are each substantially flush with the body of the motor vehicle. For example, the first and / or the second door should be locked.

The request is made for example by means of a switch in an interior of the motor vehicle. Alternatively, for example, a switch is connected to a body or to one of the two doors. In another alternative, a radio key or other portable device has a switch. For example, the request is made by operating the switch in a specific pattern, in particular during an operation for a certain period of time, for example 3 seconds or 5 seconds. Alternatively, the switch is explicitly provided and set up only for the preparation of the request. In particular, the request is a so-called "central closing", in which all doors of the motor vehicle are to be moved to a closed position.

In a second step, a priority rule is determined. The priority rule is used to control the first electric motor door adjustment and the control of the second electric motor door adjustment. For example, the priority rule is stored in a memory of the system or is generated / created on the basis of further parameters or specifications. By means of the priority rule, for example, a speed and / or a speed profile is determined by means of which the closing movement of the first and the second electromotive door adjustment is to be carried out. The priority rule is For example, always the same and / or matched to the vehicle. Alternatively, the priority rule is determined based on current requirements. In a further step, the first electromotive door adjustment and the second electromotive door adjustment are controlled on the basis of the priority rule. Suitably, for this purpose, a specific parameter data set is transmitted to a control unit of the respective electromotive door adjustment. Alternatively, the electric motors of the two electromotive door adjustments are operated on the basis of the priority rule by means of a common control unit. Appropriately, a control of the electric motors to a certain speed, which is predetermined by means of the priority rule. If the system has further electromotive door adjustments, the priority rule also preferably serves to control the further electromotive door adjustments, and these are also suitably controlled on the basis of the priority rule.

Upon request, both doors are moved to the closed position, which increases comfort. It also makes it possible to respond to current requirements by means of the priority rule, which further increases comfort. It is also possible, by means of the priority rule, to keep a load on the vehicle electrical system of the motor vehicle comparatively low, if this is specified by means of the priority rule. As a result, a burden on the electrical system is reduced and it is possible to make this less robust. In particular, for this purpose a capacity of a battery is reduced and / or a line cross-section of any cables is reduced, which reduces a weight of the motor vehicle.

Preferably, based on the priority rule, an end of the closing movement of the first electromotive door adjustment to an end of the closing movement of the second electromotive door adjustment time offset. In other words, due to the priority rule, the closing movement of the first electric motor door adjustment is terminated at a time other than the closing movement of the second electric motor door adjustment. Conveniently, the first door of the first electric motorized door adjustment is already in the closed position when the second door is still adjusted. Suitably, an energization of the first electromotive door adjustment is terminated here, while an energization of the second electric motor door adjustment is still maintained. If the system has further electromotive door adjustments, preferably all the ends of the respective closing movements are offset in time with each other based on the priority rule, so that the doors are each time-delayed spent in the respective closed position.

For example, the electric motors of the two electromotive door adjustments are controlled at a different speed, at least in time and / or in sections, on the basis of the priority rule. Suitably, the electric motors are operated at the same speed, as long as the displacement of one of the doors to the respective closed position is greater than the displacement of the door of the remaining electric motorized door adjustment, which improves a visual impression for a user of the motor vehicle.

Due to the time offset of the staggered completion of the two closing movements maximum power consumption of the two electric motor door adjustments is limited when the respective door is driven against a stop and / or against a block to ensure a secure closing of the respective door. In a blocking of the electric motor due to a stopper against which the door is moved in the closed position, the current consumption is comparatively large, which is why in this case a comparatively large electric current and thus a comparatively large load of the electrical system of the motor vehicle occurs. Due to the time offset occurs caused by the two electric motor door adjustments load of the electrical system on time, so that a maximum load is reduced, which would otherwise lead to damage, for example, any wiring of the electrical system and / or triggering a circuit breaker / fuse. Due to the staggered termination also an increase in the air pressure in an interior of the motor vehicle is avoided, which could otherwise lead to an impairment of the comfort of a person located inside the motor vehicle. Also, a noise is reduced.

For example, the closing movement of the first electromotive door adjustment is started with a time delay to the closing movement of the second electromotive door adjustment. For example, the first electromotive door adjustment is activated first and thus the first door is adjusted. Only when the first door has been moved for a certain period of time, in particular 1 second, 2 seconds, 3 seconds, 5 seconds or 10 seconds, the electric motor of the second electric motorized door adjustment is activated, thus adjusting the second door. Suitably, the second door is already adjusted, as long as the first door is still adjusted. Alternatively, the second door is not adjusted until the first door has been moved to the closed position. In other words, the adjustment of the first door is first terminated, and subsequently the adjustment of the second door is received, which leads to a further reduced load on the electrical system of the motor vehicle.

For example, based on the priority rule, first the first door is moved to a first position and the second door is moved to a second position, in particular moved. Preferably, the first position is relatively small from the closed position, for example between 1 cm and 10 cm and, for example, substantially equal to 5 cm. In other words, to move the first door from the first position to the closed position requires only a further 5 cm of movement of the first door. The second position is preferably comparatively slightly spaced from the assigned closed position, for example between 1 cm and 10 cm, in particular substantially equal to 5 cm. In other words, only a further movement of the second door by 5 cm is required to spend the second door in the closed position. Suitably, the first position is as far from the associated closed position as the second position is away from the associated closed position. For example, in the first and / or second position, the respective door is loosely attached to a body of the motor vehicle and / or it is possible that a closing mechanism of the respective electric motor door adjustment in the first and second position can attack on the respective door.

The first door and the second door are simultaneously moved to the first position and the second position. In other words, the electric motors of the respective electromotive door adjustment are simultaneously controlled and thus energized, which is why the two doors are simultaneously moved to the first or second position. The first door is moved from the first position to the closed position, in particular traversed. Also, the second door is moved from the second position to the closed position, in particular traversed. In this case, the transfer takes place from the first or second door in the respective closed position with a time delay. For example, the second door is held in the second position until the first door is in the closed position and / or an energization of the electric motor of the first electric motor door adjustment is terminated. Only then is the second door moved from the second position to the closed position. Thus, the second door is stopped for a certain period of time in the second position.

Consequently, on the one hand a comparatively fast movement of the doors is ensured, so that they are only comparatively small spaced from the body, namely in the first and second position. On the other hand, a load on the electrical system is reduced due to the time-delayed transferring into the respective closed position. In addition, formation of an increased air pressure in the interior of the motor vehicle due to the slamming of the respective door is avoided, since any air can escape, for example, through a slot formed between the closed position and the first / second position. Also, the second position is relatively small spaced from the body, so briefly only a comparatively small increase in the air pressure due to the introduction of the second door takes place in the closed position.

If the system has further electromotive door adjustments, the doors of the respective further electromotive door adjustment are placed in an associated position, which is spaced from the respective closed position is, preferably less than 15 cm, in particular between 2 cm and 10 cm. In this case, the bringing of these doors takes place at the same time as the first and second doors are moved to the first and second positions. The transfer to the respective closed positions takes place with a time lag.

Preferably, the first electromotive door adjustment and the second electromotive door adjustment are controlled such that the first door reaches the first position at the same time as the second door, the second position. For example, the adjustment of the two electric motor door adjustments is adjusted. Suitably, the adjustment of one of the two electric motor door adjustments is at least temporarily increased. Alternatively or in combination, for example, the closing movement of the first electromotive door adjustment is started with a time delay to the closing movement of the second electromotive door adjustment. In other words, the energization of the electric motor of one of the two electric motor door adjustments is started earlier. Due to the simultaneous achievement of the first or second position, an optical impression and a quality impression are increased for a user of the motor vehicle. If further electromotive door adjustments are present, these are expediently also controlled such that the doors of the other electric motor door adjustments reach their respective position simultaneously with the first and second door.

In particular, the priority rule is determined based on a potential hazard. In other words, first a potential source of danger is determined and based on which the priority rule is determined, for example, created. For example, an approaching motor vehicle, an approaching cyclist, or an approaching pedestrian are detected. Suitably, by means of the priority rule, the electromotive door adjustment closest to the source of the danger is first actuated so that the door of this electromotive door adjustment is moved out of the danger zone or does not represent a danger. Thus, if, for example, the first electric motorized door adjustment is on a side of the motor vehicle on which the cyclist is approaching, and the second electric motorized door adjustment is located on the opposite side of the motor vehicle, the first electromotive door adjustment is first operated and the first door is moved to the closed position. Therefore, the cyclist can pass the motor vehicle substantially unhindered. As a result, a potential hazard of the motor vehicle and a probability of damage to the motor vehicle is reduced.

Alternatively or in combination, the priority rule is determined based on a current environmental condition. As an environmental condition, for example, a parking space of the motor vehicle is used. Thus, for example, first that of the electromotive door adjustments is actuated, which is located on a side of the road, so on a lane side facing the motor vehicle. Only after this, the door is preferably spent in the closed position, which is for this purpose on the opposite side of the motor vehicle, or for example the tailgate, if the electromotive door adjustment has the tailgate as a door. Alternatively, for example, a prevailing wind or the like is used as the current ambient condition, and initially operated on the windward side located electromotive door adjustment, so that penetration of wind masses is prevented in the interior of the motor vehicle.

Alternatively or particularly preferably in combination with this, the priority rule is determined based on a position of the first electromotive door adjustment with respect to a position of the second electromotive door adjustment. Preferably, the one of the two electromotive door adjustments is first operated, which is located in the rear direction. Therefore, first the door further back, so that door, by means of which, for example, an entry to a second or third row of seats is possible, spent in the closed position. Only then is the electromotive door adjustment actuated and the door is brought into the closed state, which allows access to a first row of seats of the motor vehicle, ie to a driver's seat and a passenger seat. In this way, for example, a stepping out of children or other passengers from the motor vehicle is avoided.

For example, first the door of the electromotive door adjustment is spent in the closed position, which is assigned to a passenger side of the motor vehicle. Only after this is the door of the driver's seat assigned electromotive door adjustment expediently spent in the closed position. Thus, it is possible for the driver of the motor vehicle even after a comparatively long period of time to leave the motor vehicle, in particular if, for example, one of the passengers of the motor vehicle has further needs or a problem. If the process is interrupted by the driver, at least one of the doors is already in the closed position. Suitably, the boot lid is relatively late, for example, as the last door, spent in the closed position based on the priority rule. Alternatively, the trunk lid is spent as the first door of all electric motorized door adjustment in the closed position, so that removal of objects from the trunk is prevented by an unauthorized person.

Preferably, the priority rule is determined based on a Verstellpfads the first door and a Verstellpfads the second door. If the adjustment path is substantially rectilinear, and thus the door is a sliding door, this is expediently initially moved to the closed position. Only after this, for example, the door is actuated, the adjustment path runs along a circular motion, that is, which is pivoted to reach the closed position.

Suitably, for example, the priority rule is determined based on a place of creation of the request. Thus, first the place of creation of the request is determined. In particular, it is first determined whether the request was made within the motor vehicle or outside the motor vehicle. If the place of construction is located inside the motor vehicle, that is, if a user of the motor vehicle within the motor vehicle preferably operates a switch, the electromotive door adjustments located behind in the direction of travel are suitably actuated first and preferably their respective doors first spent in the associated closed position. As a result, a disembarkation of any persons located on rear benches, such as children, is excluded, the driver, for example, can still get out to support the rear seated people. Suitably, the driver's door is finally moved to the closed position.

If the construction site is outside the motor vehicle, the door located on the side of the motor vehicle facing away from the construction site is first of all moved to the closed position or initially adjusted. Only after this, the door located on the side facing the site of the motor vehicle is suitably moved to the closed position. When the request is made by the user, it is ensured that there is no obstacle or the like on the side of the motor vehicle facing away from the construction site. However, it can only be comparatively difficult to monitor whether, for example, an obstacle moves there. On the other hand, such monitoring on the site of the motor vehicle facing the site is possible. As a result, security is increased due to the priority rule.

For example, the priority rule is determined from a device by means of which the request is made, as appropriate a handle, a switch, a (radio) remote control or a gesture and / or voice control. Preferably, an end of the method and / or a termination of the method, in particular in the event of a fault, are signaled to a user, for example acoustically, visually or haptically.

The system is a component of a motor vehicle and has a first electromotive door adjustment with a first door. Furthermore, the system has a second electromotive door adjustment with a second door. The two electromotive door adjustments are, for example, identical or at least similar to each other, in particular mirror images of each other. Furthermore, the system has a control device which is preferably signal-technically coupled to the two electromotive door adjustments. The control device is operated according to a method in which first a request to perform a closing movement of the first door and to carry out a closing movement of the second door is detected. Further, a priority rule for driving the first electric motor door adjustment and for driving the second electric motor door adjustment is determined. Based on the priority rule, the first electromotive door adjustment and the second electromotive door adjustment are controlled. Preferably, the control device is suitable, in particular provided and arranged to perform the method. Conveniently, the system is used to perform the method. For example, each of the electromotive door adjustments has a control and by means of the control device, the priority rule or at least a part of the priority rule is transmitted to the respective control. Alternatively, the control of the electric motors of the two electric motor door adjustments takes place by means of the control device. Suitably, the control unit comprises a memory in which the priority rule is stored.

The refinements and advantages embodied in connection with the method for operating a system of a motor vehicle are also to be transferred analogously to the system of a motor vehicle and vice versa.

Corresponding parts are provided in all figures with the same reference numerals.

In Fig. 1 is a method of operating an in Fig. 2 shown in a plan view system 4 of a motor vehicle 6. The system 4 has a first one Electromotive door adjustment 8 with a driven by means of an electric motor not shown first door 10. Furthermore, the system 4 comprises a second electromotive door adjustment 12 with a second door 14 driven by an electric motor (not shown). The first door 10 is a driver's door, and the second door 14 is a passenger's door. In addition, the system 4 has a third electric motorized door adjustment 16 with a third door 18 driven by an electric motor (not shown) and a fourth electric motorized door adjustment 20 with a fourth door 22 driven by an electric motor (not shown). The third door 18 and the fourth door 22 are associated with a second row of seats of the motor vehicle 6, so that this allows access to this row of seats. The third door 18 is located on the driver's side and the fourth door 22 on the passenger side, so on the side of the second door 14. The first electric motor door adjustment 8 is mirror image of the second electric motor door adjustment 12, and the third electric motor door adjustment 16 is a mirror image of the fourth electric motor Door adjustment 20. In addition, the system 4 includes a fifth electromotive door adjustment 24 with a fifth door 26 in the form of a tailgate, which is driven by an electric motor, not shown. The electric motors of the electric motor door adjustments 8, 12, 16, 20, 24 are brushless and identical.

Furthermore, the system 4 has a control device 28 and an input device 30. The input device 30 is a switch integrated in a center console. The control device 28 is signal-technically and electrically coupled to the input device 30 and to the electromotive door adjusters 8, 12, 16, 20, 24. In addition, the energization of the electric motors of the electric motor door adjustments 8, 12, 16, 20, 24 takes place by means of the control device 28. Here, by means of the control device 28, a rotational speed and a direction of rotation of the respective electric motors are specified. The system 4 also includes a radio control 32, which is integrated in a key of the motor vehicle 6. Upon actuation of the radio control 32 or the control device 28 by a user 34, an activation of the electromotive door adjustments 8, 12, 16, 20, 24 takes place.

The method, which is carried out by means of the control device 28, provides that in a first step 36 a request 38 for carrying out a closing movement of the first door 10 and the second door 14 and the third door 18 as well as the fourth door 22 and the fifth Door 26 is detected. The request 28 is created by the user 34 using the input device 30 or the radio control 32 and corresponds, for example, to the "central closing" function. First, it is checked whether the doors 10, 14, 18, 22, 26 are in an open position, which in Fig. 2 is shown. If one of the doors 10, 14, 18, 22, 26 is already in a closed position, the request 38 is modified such that the command for the closing movement of this door 10, 14, 18, 22, 26 is removed.

In a subsequent second step 40, a priority rule 42 for driving the first electric motor door adjustment 8, the second electric motor door adjustment 12, the third electric motor door adjustment 16, the fourth electric motor door adjustment 20 and the fifth electromotive door adjustment 24 is determined. The priority rule 42 is retrieved from a memory of the controller 28 or redetermined. Here, a current ambient condition 44 is first determined, for which it is first determined where a lane 46 with respect to the motor vehicle 6 is located. This is located in the example on the side of the first door 10 and the third door 18. Also, a construction site 48 of the request 38 is determined. The request 38 has been made in the example by means of the radio control 32 which the user 34 holds in his hand. The user 34 is located next to the passenger door 14.

On the basis of the current environment condition 44 and the place of construction of the request 38, the priority rule 42 is determined. The priority rule 42 in this case contains the instruction that the doors located on the side of the lane 46, namely the first door 10 and the third door 18, should first be moved to the closed position. Of these, first, the third door 18 should be closed, since this is the furthest away from the place of construction 46.

Following this, the fourth door 22 and then the second door 14 are to be closed, since these are on the side facing away from the lane 46 of the motor vehicle 6, of which the first place 46 of the two doors should be closed. Finally, the fifth door 26 should be closed, since this is not a side door, but a tailgate.

In a subsequent third operation 50, the first, second, third, fourth and fifth electromotive door adjustment 8, 12, 16, 20, 24 are controlled on the basis of priority rule 42. Here, first, the first, second, third and fourth electromotive door adjustment 8, 12, 16, 20 are activated at the same time and the first door 10 in a first position 52, the second door 14 in a second position 54, the third door 18 in a third Position 56 and the fourth door 22 is pivoted to a fourth position 58. In the first position 52, the first door 10 is only loosely attached to the body. Also in the second position 54, the second door 14 and at the third position 56, the third door 18 is only loosely on the body of the motor vehicle 6 at. In the fourth position 58, the fourth door 22 loosely abuts against the body of the motor vehicle. The electromotive door adjusters 8, 12, 16, 20 are controlled in such a way that the first door 10 reaches the first position 52 and the second door 14 reaches the second position 54 at the same time. Also, the third door 18 reaches the third position 56 and the fourth door 22 reaches the fourth position 58 at the same time. For this purpose, the drive speed of the electric motors and the beginning of the energization are suitably adapted.

As soon as each of the doors 10, 14, 18, 22 has reached the respectively assigned position 52, 54, 56, 58, the respective electric motor is stopped. Following this, first the third door 18 is moved to the closed position. Once this is done, the first door 10 is placed in the closed position. Following this, the fourth door 22 is placed in the closed position. Once the fourth door 22 is in the closed position, the second door 14 is also placed in the closed position. In other words, the first, second, third and fourth doors 10, 12, 18, 22 are displaced in time from the first, second, third and fourth positions 52, 54, 56, 58, respectively, into the respective closed position. When moving to the closed position, a closing aid of the respective electromotive door adjustment 8, 12, 16, 20 is used and the respective door 10, 14, 18, 22 is pivoted onto the body until a movement due to a stop on the body is prevented , In this case, a current consumption of the respective associated electric motor is comparatively high. Due to the time offset, a maximum load on the electrical system providing the required electrical energy is reduced, which is why cost-effective lines and a low-cost battery can be used. In addition, due to the time-delayed closing of the doors 10, 14, 18, 22, a structure of a comparatively high air pressure within the motor vehicle 6 is avoided.

When the second door 14 is in the closed position, the fifth electric motor door adjustment 24 is also activated and the fifth door 26 is pivoted to the closed position. In this case, the pivoting takes place, for example, continuously. In other words, the adjustment of the tailgate 26 is not interrupted. In summary, due to the priority rule 42, the end of the closing movements of the first electromotive door adjustment 8 to the end of the closing movement of the second electromotive door adjustment 12 is time-delayed. Also, the ends of the closing movement of the other electromotive door adjusters 16, 20, 24 are each time-delayed. Furthermore, the closing movement of the fifth electromotive door adjustment 24 is started with a time delay to the closing movement of the first, second, third and fourth electromotive door adjustment 22.

In Fig. 3 another situation is shown for determining the priority rule 42, wherein the current environmental conditions 44 are the same. Thus, the lane 46 is in turn on the side of the first and third door 10, 18. In addition, however, a potential hazard source 60 in the form of a cyclist 62 is present, which approaches from the back of the motor vehicle 6 and its travel on the motor vehicle. 6 on the side of the second and fourth door 14, 22 passes. From the user 34, not shown, is used to close the Doors 10, 14, 18, 22, 26, the input device 30 is actuated so that the creation site 48 is located within the motor vehicle 6.

Based on the current ambient condition 44, the potential hazard source 60 and the place of construction 48, the priority rule 42 is determined again and the electric motor door adjustments 8, 12, 16, 20, 24 are controlled accordingly. Here, first, the fourth door 22 and the second door 14 is moved to the closed position, wherein the closing movement of the second electromotive door adjustment 12 is started shortly after the beginning of the adjustment movement of the fourth door 22. The fourth and second doors 22, 14 are substantially instantaneously pivoted to the closed position, and adjustment is not interrupted at the second and fourth positions 54, 58, respectively. As a result, the second and fourth doors 14, 22 are moved out of the way of the cyclist 62 so that injury to the cyclist 62 and damage to the motor vehicle 6 is avoided.

Following this, the third door 18 is pivoted to the third position 56 and at the same time the first door 10 to the first position 52. Subsequently, the third door 18 is first pivoted into the closed state and, following this, the first door 10 is pivoted into the closed position. Finally, in turn, the fifth door 26 is pivoted to the closed position. Thus, the closing movement of the first electric motorized door adjustment 8 is started with a time delay to the closing movement of the second electromotive door adjustment 12.

In Fig. 4 a modification of the motor vehicle 6 is shown, wherein the third and fourth door 18, 22 are each designed as sliding doors, so that they have a linear displacement path. On the other hand, the adjustment path of the first and second doors 10, 14 is in turn circular arc. In other words, the first and second doors 10, 14 are pivoted to open and close, whereas the third and fourth doors 18, 22 are moved to open and close. The actuation is again effected by means of the input device 30, so that the construction site 48 of the request 38 is located inside the motor vehicle 6. Since the adjustment path of the third and fourth electromotive Door adjustments 16, 20 is substantially rectilinear, and since the construction site 48 is located within the motor vehicle 6, first, the third and fourth electric motor door adjustment 16, 20 are operated because most children are on the rear seat of the motor vehicle 2.

Consequently, the priority rule 42 is determined such that first the third door 18, which is potentially located on the side of the lane 46, and subsequently the fourth door 22 are closed. Following this, the front passenger side is to be closed first and thus the second door 14 are moved to the closed position. Only then is the first door 10 to be brought into the closed position, so that a driver of the motor vehicle 6 can still get off, for example, and support other persons. In this case too, the method 2 would be interrupted, although comparatively many of the doors 10, 14, 18, 22, 26 are already in the closed position. In summary, the priority rule 42 is also determined based on the position of the first electromotive door adjustment 8 with respect to the position of the second electromotive door adjustment 12, namely such that the driver's side is closed last.

In summary, the door movements are adjusted in dependence on the movement of the other doors 10, 14, 18, 22, 26. In this case, the electromotive door adjustments 8, 12, 16, 20, 24 are preferably actuated in chronological succession, in particular only slightly delayed. Alternatively or in combination, the doors 10, 14, 28, 22, 26 are moved such that they are almost in the closed position. There, the doors 10, 14, 18, 22, 26 stopped and spent one after the other in the respective closed position. Additionally or alternatively, an adjustment of the movements of the individual doors 10, 14, 18, 22, 26, in particular their speed and / or position, to allow a uniform method of all doors 10, 14, 18, 22, 26.

Because of this, a load on the battery of the motor vehicle 6 is relieved when closing and pressing the respective closing aid. Also are comparatively avoided pronounced peaks in the electric current, which are caused, for example, by all the closing aids and / or electric motors are operated simultaneously. Due to a time-delayed control of the individual electromotive door adjustments 8, 12, 16, 20, 24, all the doors 10, 14, 18, 22, 26 are closed within a comparatively short period of time, current peaks are avoided due to the activation of the respective associated Zuziehhilfen. In a method of the individual doors 10, 14, 18, 22, 26 in the almost closed position and the subsequent successive closing of the individual doors 10, 14, 18, 22, 26 current peaks are avoided due to the activation of the closing aid. In the adjustment of the movement of the individual doors 10, 14, 18, 22, 26 an optical impression for the user 34 is improved.

The invention is not limited to the embodiments described above. Rather, other variants of the invention can be derived therefrom by the person skilled in the art without departing from the subject matter of the invention. In particular, all the individual features described in connection with the individual embodiments are also combinable with one another in other ways, without departing from the subject matter of the invention.
