Description

Technical field

[0001] Exemplary embodiments relate to a parking garage with at least two parking spaces. Further exemplary embodiments relate to a method for operating a parking garage or parking area with at least two parking spaces, as well as a system for such a parking garage or parking area. background

[0002] Parking garages or parking areas (such as parking lots) are regularly designed with a maximum vehicle weight in mind. Regulations or standards governing the design of parking garages, for example, stipulate a maximum total vehicle weight of up to 30 kN / 3 tons. Other parking garages may have significantly lower limits; for instance, the maximum permissible vehicle weight for some public parking garages is 2.5 tons. The load-bearing capacity of such a parking space can therefore be, for example, 3 tons or 2.5 tons.

[0003] Access restrictions for parking garages are therefore always dependent on the total weight of the vehicle; as mentioned, these values ​​are, for example, 2.5 tons or 3 tons per vehicle. Access with heavier vehicles is thus not permitted with regard to the load-bearing capacity design according to current standards, and is prohibited, for example, according to the terms of use of these parking garages. The trend in the automotive industry, however, is towards ever-increasing vehicle weights; for example, large vehicles (e.g., passenger cars) with a permissible total weight of over 3 tons can exceed the standardized design values ​​of parking garages with regard to the maximum permissible vehicle weight.

[0004] However, due to the long lifespan of parking garages (e.g., compared to the availability of new vehicles), it is usually not economical to build new parking garages designed to meet standards for new, heavier vehicles. Therefore, the use of parking garages is sometimes prohibited and thus not possible for such heavy vehicles.

[0005] DE 10 2019 114 652 A1 discloses a parking device comprising a truss made of steel beams with several parking levels arranged one above the other, each having at least two parking spaces arranged next to each other for one truck.The parking spaces are designed in the form of shelves that are movable horizontally and vertically within the truss structure. Each shelf rests on several, preferably three, horizontally pivotable lifting forks, each of which is guided by at least two deflection shafts arranged in the upper area of ​​the parking device. Preferably double-row pull chains are suspended from these deflection shafts, so that each shelf is height-adjustable via an electric motor and / or hydraulic drive, preferably with an intermediate hydraulic cylinder. Each shelf is provided on both end faces with support rollers projecting towards the adjacent horizontal truss girder, which rest on a horizontal rail guide of the horizontal truss girder in such a way that the guides are also horizontally movable.

[0006] CN 107 859 395 A describes a technical disclosure in the field of parking systems and parking equipment and provides a method of operation for a three-dimensional parking frame parking management system. The method of operation of the three-dimensional parking frame parking management system solves the technical problem that parking and retrieving vehicles is inconvenient in the prior art and includes parking steps. A camera captures images of a vehicle license plate on a license plate frame, a license plate identification unit identifies the license plate of a vehicle to be parked, and a display screen shows the images of the license plate captured by the camera and guides the vehicle to be parked on the license plate. A weighing unit on the license plate frame weighs the vehicle to be parked on the license plate.If the weight of the vehicle to be parked exceeds the preset load capacity of a parking space, the vehicle lifts off the license plate. A lifting device raises the parking space to the appropriate parking level and slides it into place to secure the vehicle. Summary

[0007] One of the purposes of this disclosure is to provide improved concepts for parking garages and for the operation of parking garages.

[0008] This problem is solved according to the subject matter of the independent claims. Further advantageous embodiments are described in the dependent claims, the following description, and in conjunction with the figures.

[0009] Accordingly, a parking garage with at least two parking spaces, and in particular a large number of parking spaces, is proposed. The parking garage includes a storage unit containing information regarding the static load-bearing capacity of each of the at least two parking spaces. Furthermore, the parking garage includes a device for recording the weight of a vehicle and an analysis unit for determining whether at least one of the parking spaces has a sufficient load-bearing capacity for the vehicle's weight. An output device of the parking garage is designed to issue an entry permit to the vehicle if at least one of the parking spaces has a sufficient load-bearing capacity for the vehicle's weight, or to issue an entry prohibition to the vehicle if none of the parking spaces has a sufficient load-bearing capacity for the vehicle's weight.

[0010] For example, the parking garage may have numerous parking spaces on multiple levels. At least two of the parking spaces may have different load-bearing capacities. For instance, one of the parking spaces may have a load-bearing capacity greater than that specified in the parking garage's design standard (e.g., because the load-bearing capacity was calculated for full occupancy of the parking garage, or because the standardized load-bearing capacity is based on a parking space with the lowest load-bearing capacity to generally prevent overloading).

[0011] According to the proposed concept, unlike other concepts that, for example, use a general weight limit, it is possible to assess the load-bearing capacity of each of the at least two parking spaces separately and to issue an entry ban to the vehicle only if neither of the at least two parking spaces is designed for the vehicle's weight. For example, individual parking spaces in the parking garage may have a load-bearing capacity that exceeds the standard load-bearing capacity of the parking spaces in the garage. For example, most of the parking spaces in the parking garage may be designed for vehicle weights under 3 tons, but individual parking spaces may have actual higher load-bearing capacities. Heavier vehicles can then be assigned, accordingly, those parking spaces that are suitable for the respective vehicle weight.The vehicle must only be turned away if none of the available parking spaces has a sufficient load-bearing capacity for the vehicle's weight.

[0012] Information regarding the load-bearing capacity of the various parking spaces can be stored directly in the parking garage's system. Alternatively, the parking garage can access a cloud-based system or obtain the respective static load-bearing capacities of each parking space via an online solution.

[0013] The device for determining the vehicle's weight could, for example, be a scale located at the entrance to the parking garage, capable of determining the vehicle's current weight. Alternatively, a camera could, for example, detect the vehicle type and calculate a corresponding vehicle weight. The device could then prompt the driver to provide the vehicle's weight or other vehicle information (e.g., by entering this information into a parking garage system).

[0014] The parking garage may, for example, have an entrance barrier (e.g., located in the direction of travel behind the vehicle weight measurement device) and / or a display panel that allows information to be transmitted to the driver of a vehicle to be parked and, if necessary, grant or deny entry to the parking garage. If, for example, one of the at least two parking spaces is suitable for the vehicle, the display panel can show the driver which of the at least two spaces to park the vehicle in, i.e., which space is assigned to them by the parking garage. If, for example, both of the at least two parking spaces are suitable, the driver can be shown that they can park in either of the at least two spaces. If, on the other hand, the total weight of the vehicle exceeds the load-bearing capacity of both parking spaces, the driver can be shown that their vehicle is too heavy for the parking garage and entry will be prevented (e.g., by a sign indicating that the vehicle is too heavy for the parking garage).the barrier will remain closed).

[0015] The proposed concept could, for example, make it possible to allow vehicles to enter an existing parking garage that would not be permitted to park in the parking garage according to a standardized maximum permissible vehicle weight.

[0016] One example involves a parking garage where the weight measurement system includes a vehicle scale. The scale is designed to measure the vehicle's weight, broken down by the weight distribution across at least two of the vehicle's wheels. In other words, the vehicle's weight distribution can be determined. For example, the weight can be divided into the weight distribution across the front and rear axles. The weight distribution across each wheel (e.g., the contact pressure of each wheel) can also be determined individually.

[0017] For example, information on the load-bearing capacity of at least two parking spaces can include information on the load-bearing capacity of individual zones within each parking space. For instance, the front section of the parking space might have a higher load-bearing capacity than the rear section. By determining or providing the vehicle weight distributed between the front and rear axles, the heavier part of the vehicle can be parked in the parking space zone with the higher load-bearing capacity. The vehicle can then be assigned a parking position (e.g., driving forward or backward into the parking space).

[0018] An example concerns a parking garage where the dispensing device includes a display device, a parking ticket and / or a radio-based transmitting unit, wherein the radio-based transmitting unit is designed to send information to the vehicle so that the information can be issued from a vehicle dispensing unit to a vehicle user.

[0019] The output device can inform the user of the vehicle to be parked, for example, whether they can enter and, if so, in which parking space they can or should park their car (e.g., if the parking garage assigns a specific space to the vehicle). Sending this information to the vehicle can, for instance, enable the user to be navigated to the parking space (e.g., if the parking garage has multiple rows and / or levels). Alternatively, if no parking space has a suitable load-bearing capacity for the vehicle, the user can be offered an alternative nearby parking garage with available spaces of sufficient capacity (e.g., the parking garage may be connected to other parking garages via a data connection).

[0020] Further details and aspects are mentioned in connection with the embodiments described above or below. The described embodiment of the parking garage may have one or more optional additional features corresponding to one or more aspects mentioned in connection with the proposed concept or with one or more embodiments described below (e.g., the method described below).

[0021] One aspect concerns a procedure for operating a parking garage or parking area with at least two parking spaces. The procedure includes providing information regarding the respective static load-bearing capacity of the at least two parking spaces. The procedure further includes determining the weight of a vehicle to be parked and assigning one of the at least two parking spaces for parking the vehicle based on the vehicle's weight, provided that at least one of the parking spaces has a load-bearing capacity sufficient for the vehicle's weight.

[0022] For example, the two parking spaces may each have different load-bearing capacities. If both parking spaces are designed to support the vehicle's weight, the vehicle or its user can be informed that both spaces are assigned to them and that they can choose one. If only one of the parking spaces is suitable for the vehicle's weight, the vehicle will be assigned the suitable parking space, and this will be communicated to the vehicle or driver.

[0023] However, it may happen that the parking garage or parking area (e.g., parking lot) has no parking space, or none that is available, suitable for the vehicle's weight. In this case, if neither of the at least two parking spaces has sufficient load-bearing capacity for the vehicle's weight, entry can be prevented. For example, the display system can show that entry is not permitted. Alternatively or additionally, entry can be prevented by a barrier.

[0024] For example, the parking space with the smallest difference in load-bearing capacity compared to the vehicle's weight can be assigned to the vehicle. If, for instance, several of the two parking spaces are suitable for the vehicle, the space with the lowest permissible load-bearing capacity can be assigned. This advantageously allows other parking spaces with higher load-bearing capacities to be reserved for other vehicles (e.g., heavier cars or vehicles). This can, for example, lead to improved utilization of available parking spaces.

[0025] According to one example, information regarding the load-bearing capacity of each parking space is provided by means of at least one of the following methods: a structural analysis of the parking garage or parking area, a simulation of the parking garage or parking area, or a load-bearing capacity measurement. The load-bearing capacity can be determined for each individual parking space using known methods for calculating building statics (e.g., taking into account the building materials used). The analysis can be performed, for example, using 3D simulation to determine the load-bearing capacity more precisely. A measurement can be performed, for example, using strain gauges to determine the load-bearing capacity of parking spaces in existing parking garages. The load-bearing capacity can be determined with an accuracy of, for example, 250 kg per parking space (or 100 kg per parking space).

[0026] For example, information regarding the load-bearing capacity of at least one parking space can be provided separately for at least two zones within that space. For instance, the load-bearing capacity of two zones can be provided or determined. The load-bearing capacity for each parking space zone can be determined with an accuracy of, for example, 250 kg per zone (or 100 kg per zone). Simultaneously, the vehicle's weight can be determined, distributed across at least two wheels (e.g., front axle / rear axle, left / right side of the vehicle). In combination, for example, if the vehicle's weight is unevenly distributed, the heavier part of the vehicle can be assigned to the parking space zone with the higher load-bearing capacity. By specifying the parking position (e.g., forward or reverse parking), the parking space utilization of the parking garage can be improved.For example, assigning a parking space to a vehicle includes assigning a parking position for the vehicle within that space. For instance, a parking space may only be permitted for one specific parking position (e.g., forward or reverse parking).

[0027] For example, the load-bearing capacity of a parking space can be divided into at least three longitudinal zones. If, for instance, only one of the rear longitudinal zones has a low load-bearing capacity, the parking space can be assigned to a vehicle with a short wheelbase, which would, for example, only occupy two front longitudinal zones with sufficient load-bearing capacity. A corresponding parking instruction can be given to the vehicle or driver, for example, via the display device (e.g., the instruction to park in the front area of ​​the parking space).

[0028] For example, when providing information regarding the load-bearing capacity of parking spaces, the current occupancy status of parking spaces in the parking garage or parking area can be taken into account. The load-bearing capacity of a parking space can depend on whether an adjacent parking space is occupied or vacant. For instance, even if the current load-bearing capacity of some parking spaces is reduced due to high occupancy of the parking garage, it is possible to use these spaces, for example, for lighter vehicles.

[0029] For example, when determining weight, it is possible to consider the vehicle type, maximum permissible axle load, and / or the number of occupants. The parking system can store weight information for various vehicle types, allowing the vehicle type to be identified using a camera, for instance, and the maximum permissible vehicle weight or axle load to be calculated from this information. For example, fully loaded vehicles (e.g., with multiple occupants) can be heavier than empty vehicles. The vehicle's weight can also be estimated based on its size.

[0030] Further details and aspects of the method are mentioned in connection with the embodiments described above or below (e.g., parking garage or parking garage system). A described embodiment may include one or more optional additional features corresponding to one or more aspects mentioned in connection with the proposed concept or with one or more embodiments described above or below.

[0031] One aspect concerns a system for a parking area (e.g., a parking garage or a parking lot) with at least two parking spaces. The system includes a storage unit containing information regarding the load-bearing capacity of each of the at least two parking spaces and a device for recording the weight of a vehicle. The system further includes an analysis unit for determining whether at least one of the parking spaces has a sufficient load-bearing capacity for the vehicle's weight, and an output device configured to output information to the vehicle indicating which parking space is assigned to it if at least one of the parking spaces has a sufficient load-bearing capacity.

[0032] The system can advantageously be used to retrofit existing parking garages or parking lots, enabling them to be better utilized, for example, in terms of weight capacity. For instance, the load-bearing capacity of the parking spaces in an existing parking garage can be stored in the system, thus allowing the parking garage to be operated according to a method disclosed herein. This can, for example, save costs, as heavier vehicles can potentially be parked even without the need to construct new parking garages.

[0033] Further details and aspects of the system are mentioned in connection with the embodiments described above or below (e.g., parking garage or method for operating a parking garage). The embodiment shown may have one or more optional additional features corresponding to one or more aspects mentioned in connection with the proposed concept or with one or more embodiments described above or below.

[0034] The disclosed embodiments may also include one or more optional additional features corresponding to one or more aspects mentioned in connection with the following examples disclosed in the figures. Character description

[0035] Examples of implementation are explained in more detail below with reference to the accompanying figures. These show: Fig. 1 a schematic example of a parking garage with two parking spaces; Fig. 2 a flowchart of a procedure for operating a parking garage; Fig. 3a - 3e a schematic example of a vehicle occupying one of several parking spaces; and Fig. 4 A schematic example of the effect of the occupancy of a parking space on the load-bearing capacity of adjacent parking spaces. Description

[0036] Several embodiments are now described in more detail with reference to the accompanying drawings, which illustrate some of these embodiments. For clarity, the thickness dimensions of lines, layers, and / or regions may be exaggerated in the figures. In the following description of the accompanying figures, which only show some exemplary embodiments, the same reference numerals may denote identical or comparable components.

[0037] An element described as "connected" or "coupled" to another element may be directly connected or coupled to the other element, or there may be intervening elements. Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning that a person skilled in the art in the field to which the embodiments belong would attribute to them.

[0038] Fig. Figure 1 shows a schematic example of a parking garage 10 with two parking spaces P1, P2. The two parking spaces P1, P2 can be arranged next to each other or separately from each other; in particular, the parking garage 10 can comprise a large number of parking spaces.

[0039] Parking garage 10 also includes a storage unit containing information regarding the respective static load-bearing capacity of at least two parking spaces P1 and P2. The static load-bearing capacity indicates the maximum vehicle weight that vehicles may have that are permitted to be parked permanently in the parking space. Parking garage 10 also includes a device 11 for recording the weight of a vehicle 13 that is to be parked in parking garage 10.

[0040] Furthermore, an analysis unit is provided to determine whether at least one of the parking spaces P1, P2 has a sufficient load-bearing capacity for the weight of vehicle 13. For example, the analysis unit, or alternatively an allocation unit of the parking garage, can also output allocation information on which of the parking spaces P1, P2 vehicle 13 can be parked if the required load-bearing capacity is present.

[0041] The parking garage 10 also includes a dispensing device 12, which is designed to issue an entry permit to the vehicle 13 if at least one of the parking spaces P1, P2 has a load-bearing capacity sufficient for the weight of the vehicle 13, or to issue an entry prohibition to the vehicle 13 if none of the parking spaces P1, P2 has a load-bearing capacity sufficient for the weight of the vehicle 13.

[0042] For example, parking garage 10 can output parking information 12a to vehicle 13 (e.g., image display on a monitor or radio signal to vehicle 13), which includes the assignment of at least one of the parking spaces P1 or P2. Accordingly, the parking information can include navigation information so that vehicle 13 (e.g., autonomously) or a user of vehicle 13 can drive it along a predetermined route 14 through parking garage 10 to the corresponding parking space P1 or P2 and park there.

[0043] Fig. Figure 2 shows a flowchart of a procedure 20 for operating a parking garage, e.g. the one in Fig. The procedure 20 comprises providing 21 information regarding the respective static load-bearing capacity of the at least two parking spaces and determining 22 the weight of a vehicle to be parked. After comparing the available parking spaces and their load-bearing capacity with the determined 22 vehicle weight, 23 one of the at least two parking spaces can be assigned for parking the vehicle depending on the vehicle's weight, provided that at least one of the parking spaces has a load-bearing capacity sufficient for the vehicle's weight.

[0044] Unlike parking concepts that use fixed or standardized, uniform weight limits for all parking spaces, the proposed method can, for example, lead to improved utilization of parking spaces, as the load-bearing capacity of each space can be considered individually. This allows, for instance, heavier vehicles to be parked in individual spaces with high load-bearing capacity, which is not permitted under other concepts.

[0045] Further details and aspects are mentioned in connection with the exemplary embodiments described above or below. The in Fig. The embodiment shown in section 2 may have one or more optional additional features corresponding to one or more aspects that are related to the proposed concept or to one or more of the above (e.g. Fig. 1) or below (e.g. Fig. Examples of embodiments described in 3a-4) are mentioned.

[0046] Fig. Figures 3a - 3e show a schematic example of a vehicle 13 occupying one of several parking spaces P1, P2, P3, P4. For example, several vehicles 13 can be parked on a parking area 30 (e.g. in a parking garage 10) with the four parking spaces P1, P2, P3, P4.

[0047] For parking area 30, a load-bearing capacity assessment exists for each of the four parking spaces P1, P2, P3, P4 in its unloaded state. Fig. Figure 3a shows an example of an assessment of the load-bearing capacity per parking space in six separate zones of the parking space (e.g., three longitudinal zones and two transverse zones). This allows, for example, an improved allocation of a parking space to vehicle 13 depending on the vehicle weight and load-bearing capacity.

[0048] The parking zones shown have different load-bearing capacities. For example, high-load-bearing zones 1000 (marked with hatching) can support a heavier permissible weight than lower-load-bearing zones 500 (marked in white). The higher-weight zones 1000 can, for example, support a static weight of 1 ton per zone 1000. The lower-load-bearing zones 500 can, for example, have a load-bearing capacity of 500 kg per zone 500. Another zone 250 with a lower load-bearing capacity (marked with checkerboard; see also...) Fig. 4) can, for example, have a permissible load-bearing capacity of up to 250 kg.

[0049] For example, parking lot P2 can accommodate vehicles weighing up to 6 tons, as each of the high-load-bearing parking zones 1000 has a load capacity of 1 ton. Parking lot P3, on the other hand, only has a high load capacity in its rear third; the front section, for example, only has a medium load capacity.

[0050] Vehicle 13 has four wheels: a left front wheel (vl), a right front wheel (vr), a left rear wheel (hl), and a right rear wheel (hr). For example, the weight of vehicle 13 can be determined by distributing it across all four wheels (vl, vr, hl, hr). For instance, if each rear wheel (hl, hr) carries a weight of 600 kg (e.g., a contact weight), and each front wheel (vl, vr) carries a weight of 500 kg, then in this example, a rear wheel (hl, hr) could only be parked in a high-capacity parking space (zone 1000), but not in a lower-capacity parking space (zone 500) with medium load capacity, because the 600 kg wheel load exceeds the 500 kg load capacity of the medium-capacity parking space (zone 500).

[0051] The different markings of the six zones per parking space P1, P2, P3, P4 represent the maximum load heights that are statically permissible at the respective positions due to the materials used, the architectural design, or similar factors. If vehicle 13 now wants to use one of these parking spaces P1, P2, P3, P4, the following steps are performed, for example: The loads on the vehicle's contact surfaces (e.g., on the four wheels) can be identified. Furthermore, possible parking spaces P1, P2, P3, P4 can be calculated with regard to the design boundary conditions of the parking areas P1, P2, P3, P4. Finally, an individual parking space P1, P2, P3, P4 can be assigned to vehicle 13.

[0052] Identifying the loads on the contact surfaces of vehicle 13 can be done in different ways. Determining the load of a vehicle per contact surface can be achieved, for example, using one of the following approaches, which can be divided into two variants: Firstly, the vehicle can be weighed. For this purpose, a scale is installed in the parking garage, for example, in front of the entrance barrier, which determines the vehicle weight, e.g., per wheel (four-plate scale), e.g., in its loaded state. This allows for recording the current state of the static vehicle load, including occupants and luggage. Secondly, the loads can be derived based on the vehicle type. If the vehicle type is known when the vehicle enters the parking garage (e.g., through input by the vehicle user and / or camera analysis and / or data exchange between vehicle 13 and the parking garage), then, for example,The required load data is determined from a database containing the technical data of approved vehicles (e.g. permissible total weight of the vehicle, axle loads, etc.).

[0053] The required vehicle weights can be determined in the following ways, for example: Communication between the vehicle and the parking garage can take place, e.g., via radio (e.g., direct local communication or indirectly via a server; this requires, for example, compatibility of the data transmission both at the physical level (e.g., radio frequency) and at the data format level; e.g., a standardized transmission path and / or data protocol is advantageous here). If communication between the vehicle and the parking garage is possible, weight-relevant data can be transmitted, e.g., the permissible total weight of the vehicle including the permissible axle loads (which, for example, corresponds to the worst-case weight with regard to the necessary load-bearing capacity of the parking space) or the manufacturer's specifications for the vehicle according to the manual or operating instructions, as well as the number of people being transported (e.g.,(via seat occupancy sensor), loaded luggage, and / or vehicle-specific configured optional equipment, e.g., to predict a more precise assessment of the actual vehicle weight under the current load (e.g., to enable a weight estimate below the worst-case weight). Alternatively or additionally, vehicle data can be acquired based on external vehicle characteristics, e.g., optical capture of the vehicle with cameras. This can involve, for example: capturing the vehicle's exterior contours, then comparing them with a database to determine the vehicle type; reading the vehicle identification number (VIN) below the windshield – this can, for example,Furthermore, it can be used to automatically query the vehicle's special equipment configuration, which is required for a more precise calculation of the actual, current load state; to capture the model designation and thus assign the vehicle weight; and / or to capture the number of people in the vehicle.

[0054] A calculation of possible parking spaces can be performed with regard to the design constraints of the parking areas. For vehicle 13, for example, the following load distribution of the contact surfaces has been determined (e.g., by weighing): The rear wheels hl, hr can each have a contact weight of 600 kg, and the front wheels vl, vr can each have a contact weight of 500 kg. From the available parking spaces P1, P2, P3, P4, those that are compatible with this vehicle load can then be identified.

[0055] For example, vehicle 13 cannot park in parking space P1 without violating the permissible load limits (at least one rear wheel would necessarily be placed on a parking space 500 with medium load capacity, i.e. not designed for 600 kg weight).

[0056] Vehicle 13, on the other hand, may park in parking space P2 both forwards and backwards. A corresponding parking situation 31 in the reverse direction R is shown in Fig. 3b shows another parking situation 32 in the forward direction V is in Fig. 3c is shown.

[0057] In parking space P3, vehicle 13 can only park in reverse in a permissible manner (see parking situation 33 in reverse direction R according to the illustration in Fig. 3d).

[0058] In parking space P4, vehicle 13 can only park facing forwards in a permissible manner (see parking situation 34 in the forward direction V according to the illustration in Fig. 3e).

[0059] An individual parking space can be assigned (e.g., after determining which parking spaces are suitable for vehicle 13). For example, one of the compatible scenarios (P2, P3 reverse, P4 forward) can be selected. The selection can be made based on various criteria; for instance, the option that is easiest for the user can be chosen. This could be, for example, the assignment of parking space P2, since the user does not need to consider the parking direction. The user is informed of their assigned parking space and, if relevant, the parking direction (e.g., forward V or reverse R), for example, via a monitor or on the parking ticket (e.g., the ticket dispenser in the parking garage). The user can then park their vehicle 13 in the designated space.

[0060] Further details and aspects are mentioned in connection with the exemplary embodiments described above or below. The in Fig. The embodiment shown in 3a-3e may have one or more optional additional features corresponding to one or more aspects that are related to the proposed concept or to one or more of the above (e.g. Fig. 1-2) or below (e.g. Fig. 4) described embodiments are mentioned.

[0061] Fig. Figure 4 shows a schematic example (40) of the effect of the occupancy of a parking space on the load-bearing capacity of adjacent parking spaces. For example, the load-bearing capacity assessment of the remaining free parking spaces can be updated, e.g., if one of the parking spaces is occupied.

[0062] In the example shown, the Fig. 4 (Vehicle 13 parks facing forward in parking space P2) the load on parking space P2 can affect, for example, the neighboring parking spaces P1, P3, as shown in Fig. 4 is shown. In contrast to the uncontaminated state of parking area 30 (e.g. in Fig. (as shown in 3a) individual parking space zones of the adjacent parking spaces P1, P3 may now have a lower load-bearing capacity, e.g. a medium load-bearing capacity of 500 instead of a high load-bearing capacity of 1000 or a low load-bearing capacity of 250 instead of a medium load-bearing capacity of 500.

[0063] If another vehicle 13 (not shown) wants to use one of the remaining parking spaces P1, P3, P4, the updated load-bearing capacity assessment can be used to determine a suitable parking space (e.g., only a light vehicle with a front wheel load of 250 kg could now be parked in parking space P3).

[0064] For example, the vehicle's position along its longitudinal axis on a parking space can be predetermined based on its wheelbase (e.g., the distance between the front and rear axles). This can be done, for instance, in parking information when assigning a parking space to vehicle 13. In the example above, a vehicle with a shorter wheelbase, which occupies only two of the three tiles shown along its longitudinal axis, can park in the rear section of parking space P1 (e.g., the rear two-thirds with parking zones of medium load capacity (500) and high load capacity (1000)) without touching the parking zone of low load capacity (250) in the front section. The same principle can be applied, for example, to positioning along the vehicle's width axis.

[0065] Depending on the resolution of the load limits of a parking area (e.g., one or more parking zones per space), the target parking position of the vehicle can be specified with arbitrary precision. To ensure precise parking at the target position, support via an automated (or partially automated) driver assistance system is also possible.

[0066] Further details and aspects are mentioned in connection with the exemplary embodiments described above or below. The in Fig. The embodiment shown in section 4 may have one or more optional additional features corresponding to one or more aspects that are related to the proposed concept or to one or more of the above (e.g. Fig. 1-3e) or the embodiments described below.

[0067] One aspect concerns a system for weight-optimized load distribution of vehicles in parking garages. Using the described concepts, the load-bearing capacity of parking areas can be assessed situationally, thus enabling, for example, the approval of use for heavier vehicles.

[0068] The presented concept allows, for example, parking garages to be opened to vehicles whose weight exceeds a load-bearing capacity that is otherwise fixed, e.g., a standardized one. For instance, a parking space can be assigned to a vehicle based on the load on one or more of its contact points. This parking space (e.g., the selection of the parking space) can be chosen and / or optimized with regard to the load-bearing capacity of the available parking areas. For example, the parking areas in each parking garage can be individually assessed or evaluated with regard to their static load-bearing capacity. Furthermore, the resulting effects of the load on individual parking spaces, specifically the interactions of the surface loads, can be known and taken into account when allocating parking spaces. The proposed concept allows, for example,A parking garage can be better utilized, or parking can be made permissible for heavier vehicles.
