Description

The invention relates to a method according to the preamble of claim 1 to assist a road user in finding a suitable parking space for a motor vehicle and a motor vehicle according to the preamble of claim. 7

From the DE 10 2012 216 994 A1 For example, a method for car park switching and a free parking assistance system are known. In the process, road users determine information about free parking and transmit it to a cloud computing system, which retrieves the information about the free parking in a parking card retrievable. Road users may be vehicles equipped with proximity sensing devices which detect them when driving past free parking spaces. For this purpose, for example, ultrasound systems can be used. The respective vehicle thus acts as a mobile sensor system to determine a local map of free parking spaces while driving, without this affecting the driver. It can also be determined more meta-information of parking lots, which can be obtained for example by a sign recognition of temporary no-hold signs or signs for identification of residents, disabled, women or private parking.

The object of the present invention is to provide a method and a motor vehicle suitable for the method, which enable simplified and particularly reliable parking space switching.

This object is achieved by a method having the features of claim 1 and a motor vehicle having the features of claim 7.

In the method according to the invention for supporting a road user when finding a suitable parking area for a motor vehicle, it is provided that a plurality of motor vehicles involved in the method determines sensor data by means of a respective sensor and transmits this to a server device. In this case, an environmental or environmental detection or scanning of an environment of the motor vehicle or of a space surrounding the motor vehicle can serve as the respective sensor technology. The sensor data thus describe an environment of the respective motor vehicle, in particular with regard to a absence or an occupancy or blocking by a respective obstacle. The server device processes all transmitted sensor data of the plurality of motor vehicles to a parking space reservation map and makes them available to the motor vehicle of the road user, which is to be parked on a suitable storage area. The present method can thus be carried out or applied particularly advantageously in a parking space and / or in an environment of a parking space. In order to enable a simplified and particularly reliable parking space switching, it is provided according to the invention that of all involved in the process or participating motor vehicles after a respective parking in a parking lot, an instantaneous value of the respective sensor data, which concerns an extension of the respective motor vehicle free space by means of the respective motor vehicle or by means of its sensor technology is detected. This respective instantaneous value is then transmitted to the server device for updating the parking space reservation card.

A suitable storage space is a storage space, which is free and in particular has suitable dimensions or a sufficient size, so that the respective motor vehicle can be parked on the parking space as intended and without obstruction of other road users or other road users.

In the context of the present method, a parking space may be understood as meaning, in particular, an area or even a parking lot, for example a parking garage. Likewise, here also generally, in particular contiguous, areas or areas can be referred to as a parking lot, which is suitable for parking several vehicles in the immediate vicinity or proximity to each other, in particular provided. The parking space may in particular include or have several parking spaces or parking stands or parking spaces. However, these can be partially surrounded or delimited by respective, even increased boundaries.

The instantaneous value represents a complete representation or a respectively current actual state of the vehicle environment detected by the sensor system. The instantaneous value can therefore be understood or referred to as a type of screenshot or snapshot of the respective sensor data or also of the respective state or detection state of the sensor system. This static actual or instantaneous state is advantageously generated or determined after switching off the respective motor vehicle, so that it can therefore be assumed that the motor vehicle has reached and assumed its respective final parking or parking position and not, for example, for further position-changing or position-adapting parking or parking positions Correction maneuver is moved on the respective storage area. The shelf is here in particular a parking space, a parking lot or a parking space, which is provided or intended in particular for parking a single motor vehicle. This is also particularly advantageous over the prior art, since there, for example, after detecting two adjacent free parking spaces and the transmission of this information by the same motor vehicle, which has sensed the two free parking spaces in a pass, this can then be turned off here. It is quite possible that the motor vehicle is not parked as intended or in a designated manner or position, so that, for example, both parking spaces are occupied or blocked. Thus, then, the information transmitted to the server device that two or at least one free parking space is available is no longer correct, correct or current. The actual current state is detected and transmitted, for example, only at any later time by another motor vehicle passing by with activated sensor system.

Further, the present invention provides the advantage of generating or using a significantly smaller volume of data or data to create a parking space map and keep it on or in a current state at all times. In conventional methods, the same information can be transmitted, for example, by a multiplicity of motor vehicles passing successively at one and the same position. As a result, for example, corresponding data connections or data networks are unnecessarily burdened by multiple transmission of redundant information. Likewise, by the present method, a necessary for generating and keeping the parking space reservation map necessary energy expenditure on the part of the respective motor vehicles can be minimized, since the sensor data does not have to be continuously transmitted or sent while driving. This can be of particular advantage in particular with increasingly widespread electric vehicles. In addition to the sensor data acquired by the respective sensors for detecting the surroundings of the respective motor vehicle, further data can also be transmitted from the motor vehicle to the server device. This may in particular include a current position of the motor vehicle, which may have been determined, for example, by means of a satellite-supported position determination system. The server device combines or superimposes all respectively current data, it also being possible to take into account further data or information when generating the parking space reservation card. For example, it may be advantageous to use as a starting point a map or representation of the parking space determined by conventional surveying methods, which superimposes the data or sensor data transmitted by the motor vehicles or in which these data are integrated or incorporated. Likewise, for example, by taking into account the respective position of the motor vehicle, a surface area occupied by the motor vehicle itself may be defined or blocked, or at least not set free or available or suitably recognized, and / or marked, but not parked for parking another motor vehicle. The car park occupancy map may be in the form of an abstract database or dataset, but it is particularly advantageous to create a graphical or visual representation that is particularly easy for a human observer to understand and understand. This can be displayed or displayed, for example, on a respective display device, for example a respective screen or display of the motor vehicle. It may also be possible, in addition or alternatively, to transmit the parking space reservation card, for example, to a mobile terminal of a respective vehicle occupant. Furthermore, it is possible to transmit the parking space reservation card or corresponding information or data to other persons and / or facilities. Thus, the data can be provided, for example, to a traffic control system or parking guidance system by which road users can be informed, for example, at any distance to the parking lot on its occupancy or occupancy status. Likewise, it may be possible to transmit the data, for example, to an owner, supervisor or administrator of the respective parking lot. This can advantageously be used, for example, for the analysis of a utilization or use of the parking space and, if appropriate, enable optimization or adaptation based on real usage data, for example a number, size and / or orientation of the or individual shelves and / or between these running traffic routes.

The respective sensor data can be transmitted, for example via a respective wireless data connection, for example via a radio link or a mobile network to the server device. The server device can thus be for example a, in particular stationary, for example, connected to the Internet data center. The server device can also be formed or constructed flexibly or distributed, for which purpose, for example, computing or server capacities of the cloud can be used.

In a further embodiment of the present invention, it is provided that in the parking space map area areas in which no suitable for parking the motor vehicle storage space is available or available or present, are marked by a first color and the Parking the motor vehicle suitable shelves or surface areas in which a correspondingly suitable storage space is free, available or available, be characterized by a second color. In this case, preferably those areas can be marked or included in the labeling, which may for example be part of the parking lot, but this are not storage areas. By marking such areas, a particularly simple and intuitively comprehensible larger contiguous surface area may optionally be characterized uniformly. Thus, misunderstandings on the part of the road users seeking a free parking space can be avoided, for example, with respect to possibly free but not for parking of motor vehicles provided areas or areas of the parking lot. Such surface areas not provided for parking motor vehicles may include, for example, pedestrian paths, event areas, maneuvering areas, loading zones and / or other infrastructure elements or even green areas or the like. Preferably, signal colors typical for the first color and second color may be used. Thus, for example, surface areas in which no free storage space is available can be marked red and area areas in which at least one free parking space is available or available, and / or individual free parking spaces can be marked green or colored, for example.

In a further refinement of the method according to the invention, the free space determined from all instantaneous values can be colored-coded by the server device in the parking space reservation map depending on the respective extent of the free space on the basis of a predetermined color scale. In other words, in particular more than two colors can be used. In this case, different meanings can be assigned to the different colors. Thus, for example, certain expansion or size ranges or corresponding value intervals can be predetermined or defined, which are each marked with a specific color. Thus, it can be particularly easy for the road user to see whether a concrete free parking space or a free parking space is, for example, a particularly wide and therefore comfortably usable free space or if, for example, additional maneuvering or maneuvering may be necessary. In this case, it may also be possible to tailor the color coding of the parking space reservation card individually to the respective motor vehicle or the respective road user, that is to carry out an adaptation of the color coding which takes into account, for example, a size or extent or maneuverability of the motor vehicle and / or an individual preference of the respective driver can. By using the color gamut, the respective road user can, for example, be provided with a particularly easy, fast and intuitively understandable and / or particularly detailed introduction of the current occupancy state of the parking space. Overall, for example, a map or representation can result, which corresponds to a well-known about weather or temperature maps representation or equal.

In a further embodiment of the method according to the invention, it is provided that from a previously parked on a parking area motor vehicle, as soon as this is put into operation and moved away from the respective storage area, an information indicating this is transmitted to the server device and the last of this from the server device Car vehicle transmitted instantaneous value from the parking lot reservation card to be updated or removed.

In this case, the instantaneous values last transmitted by other motor vehicles parked directly next to this motor vehicle can preferably be evaluated on receipt of this information moving away from the motor vehicle, especially for determining the extension of the now freed parking area. Thus, it is possible and ensured in a particularly advantageous manner that the parking space reservation card always displays or reproduces the current and actual state or occupancy state of the parking space. In particular, this can be achieved or achieved with the present method without, for example, permanently or permanently having to activate or switch on the respective sensors or motor vehicles for detecting or monitoring their environment. After transmission of the instantaneous value of the sensor to the server device, in the present case the respective motor vehicle can thus be completely switched off or switched off, whereby advantageously an unnecessary energy consumption and an operating time of the respective sensor can be minimized within a certain period of time.

In a further embodiment of the invention, it is provided that it is determined by the server device based on the instantaneous values, whether a motor vehicle is parked obliquely to a designated orientation on a storage area. It can therefore be obliquely parked or parked motor vehicles recognize because, for example, a purpose-oriented and parked next to the parked motor vehicle motor vehicle in a front area and in a rear area different distance values to the adjacent determine or detect obliquely parked motor vehicle. On the basis of this information, which may also be shown or particularly highlighted in the parking lot occupancy map, the respective road user is made particularly advantageous, for example, to recognize or assess not only the occupancy state of a parking space but also a quality of this parking space. The quality of a parking space, for example, be affected by obliquely parked directly adjacent parking motor vehicles, since in such cases, for example, to open a door of your own motor vehicle is not enough free space available and / or, for example, a retraction in or on the parking space can be difficult.

The motor vehicle according to the invention has a sensor system for determining a free space surrounding the motor vehicle and a data processing device for exchanging information with a server device via a, in particular wireless, data connection and is set up to retrieve a parking space reservation card from the server device for finding a suitable storage area. According to the invention, the motor vehicle is further configured to automatically detect an instantaneous value of the sensor data provided by the sensor, the motor vehicle surrounding clearance indicating sensor data and to transmit this instantaneous value to the server device after stopping the vehicle on the parking area.

The functional embodiments of the method according to the invention and of the motor vehicle according to the invention and the corresponding advantages described heretofore and hereinafter as well as the corresponding advantages mutatis mutandis mutually between the method according to the invention, the motor vehicle according to the invention and / or devices used for carrying out or carrying out the method according to the invention, components and devices transferable.

Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing. The single FIGURE shows a schematic overview representation for explaining the method according to the invention.

The single FIGURE shows a schematic overview representation with various components, based on which in the following a method for supporting a road user 40 when finding a suitable storage area. The road user 40 In this case, both a motor vehicle, for example an autonomous or semi-autonomous driving or operable motor vehicle, or also a vehicle occupant, in particular a driver of the motor vehicle, may be designated. In a first part of the overview shown is a section 10 a parking lot 12 shown, which on both sides of a track a variety of individual parking spaces 14 has, of which only a few are exemplified here. The pitches 14 are present by or from motor vehicles 16 occupied or occupied, of which also only some examples are marked or designated. From the motor vehicles 16 is also an individual as a motor vehicle 18 designated.

Today, many motor vehicles already have sensor devices, for example so-called parking sensors or parking assistants, which measure or detect, for example, a distance between the respective motor vehicle and the motor vehicle surrounding objects or obstacles while driving. The distances measured in this way can be displayed or displayed to the respective driver, for example by acoustic signals, but also visually, for example by displaying bars or circular arcs. The latter can vary, for example, in their number and / or color as a function of the measured distance. To other road users 40 There are already different approaches to supporting this by providing information. For example, in a surface or top layer of the parking lot 12 , especially the pitches 14 , respective sensors installed or integrated. Thus, it can be determined whether the respective sensor is loaded or not, so that a statement can be made about whether the respective parking space 14 busy or free. Another approach is the use of radar sensors, which may be arranged in street lamps, for example. The disadvantage of these approaches is in each case a very complex necessary installation of the respective sensors. Another concept envisages other motor vehicles 16 or to use their sensors to provide information in support of the road user 40 to win, but disadvantageous the respective motor vehicles 16 can not be completely shut down because their sensors would still need to be powered for environmental monitoring with power. Be the motor vehicles 16 completely switched off or on, they can no longer collect or record or transmit any information. A continuous operation of the sensors, a respective data processing device, such as an on-board computer, and optionally respective transmitting devices with the necessary power supply from a battery of the respective motor vehicle 16 is not practical in reality.

In the present case, it is therefore envisaged that of all motor vehicles involved in the process 16 . 18 . 40 before each parking in the parking lot 12 a respective instantaneous value of the sensor data determined by the respective sensor for detecting the environment detected and to a server device 26 is transmitted. The instantaneous value is in particular one the respective motor vehicle 16 . 18 . 40 surrounding free space 20 or its extent or size. This free space 20 can be limited by obstacles, such as more of the vehicles 16 , or by a range of the respective sensors. In the present, the free space surrounds 20 in one dimension by way of example the motor vehicle 18 and is bounded laterally by adjacent to the motor vehicle 18 parked the motor vehicles 16 and in another dimension by a range of the sensors of the motor vehicle 18 , It is envisaged here that in a corresponding manner by each of the motor vehicles 16 at or after each parking on one of the pitches 14 the respective motor vehicle 16 surrounding free space was captured.

The corresponding sensor data, which the respective free space 20 can describe or specify with other data, in particular a current position of the respective motor vehicle 18 respectively 16 be bundled. In the present case is that of the motor vehicle 18 acquired instantaneous value with regard to the free space 20 together with a current position or a current location of the motor vehicle 18 to a record 22 bundled or summarized. This compact record 22 is then in the course of a single or one-time transmission 24 to the server device 26 transmitted. Although here only the example of the motor vehicle 18 transmitted record 22 is shown, corresponding records of all motor vehicles 16 at different times to the server device 26 transmitted.

The server device 26 processes all these records 22 by combination and overlay or integration with a map of the parking lot 12 , This processing 28 As a result, it provides a parking space reservation card 30 which the parking lot 12 represented visually or graphically, with occupied surface areas 32 marked or colored in a first color and free surface areas 34 marked or colored in a second color. It can of course also unrecognized surface areas 36 of the parking lot 12 which are not in a detection range of a sensor of one of the motor vehicles 16 lie. It can then be deduced that the unrecorded surface areas 36 are also free, but this is subject to a certain uncertainty, since they can indeed be occupied or blocked by other objects, objects, vehicles or the like. Accordingly, the unrecognized surface areas 36 for example, not be marked or colored in another color.

Is now the road user 40 In search of a free parking space, he can use the parking card 30 from the server device 26 Request. This is followed, for example, also via a wireless mobile connection, a provision 38 the parking lot reservation card 30 to the road user 40 , This is thus regardless of its current location, an actual current state or an actual current occupancy of the parking lot 12 displaying representation available. Based on this, the road user 40 then be advantageous to plan further action, even if he, for example, not yet in sight of the parking lot 12 located. Especially for very large parking lots 12 However, even if the road user 40 already on this is the parking card 30 be beneficial and helpful.

After the road user 40 with the help of the parking reservation card 30 found a free parking space, visited him and parked his car on this pitch, is also a corresponding record from his motor vehicle 22 to the server device 26 transmitted. This then updates the parking card 30 , so in turn by the one-time transmission of the record from the road user 40 or from the motor vehicle, a current occupancy state of the parking lot 12 determined and can be made available to other road users.
