Description

Description title

Parking sensor system for dynamic parking allocation state of the art

Parking sensors detect the occupied status of a parking space in a parking space management system, e.g. Number of free / occupied parking spaces within a parking garage. From DE 10 2009 029 720 AI is known, defined

Provide parking areas each with defined parking spaces. The sizes of the parking spaces are statically predetermined. An assignment is made according to

Vehicle size.

Disclosure of the invention

In this invention, a parking sensor system becomes dynamic

Parking allocation proposed, whereby a better and more efficient use of a given parking area can be achieved by detecting the size of the available parking lots and the vehicles to be parked. The invention includes the innovation that the parking spaces themselves are dynamic in size. A parking-seeking vehicle is not assigned an appropriate parking area, but a parking space resulting from the current situation on the spot.

The invention is based on the idea that a given parking area may be occupied by a number of "x" parking spaces with a different number of vehicles, for example a number "y" may be placed on the area.

Small vehicles (eg Smart) with x <y, or a number "z" large sedans (eg Mercedes S-Class) with x> z or a combination of different sized vehicles are parked. The invention thus makes it possible, both in "conventional" parking, in which the driver controls his vehicle to an assigned parking space, as well as in autonomous parking (eg in the so-called "automated valet parking") that each vehicle can be assigned a suitably large parking lot , In addition, it is prevented that a vehicle is controlled in too small a parking space in which the driver notices on arrival that the gap is not sufficiently large.

According to the present invention, a parking sensor system for dynamic parking allocation on a given parking area is proposed which comprises at least one parking space sensor which is designed to detect free and occupied partial areas of the parking area and to detect the size of the free partial areas. Furthermore, the system comprises a

Parking management unit which is configured to receive information about the size and location of free partial areas of the at least one parking space sensor and to allocate a free partial area as parking space to an arriving vehicle depending on the size of the vehicle.

For the purposes of the invention, the size of the vehicle is to be understood as meaning, in particular, the length and width of the vehicle. For example, in parking areas in a parking garage with varying ceiling height also the vehicle height can be considered.

At least one sensor installed within the parking area determines the size of the currently free partial areas and sends this information to a

Parking management unit (parking management system). It is advantageous to provide a plurality of sensors, which are arranged in particular at a defined distance from one another, in order to increase the measuring accuracy.

For example, the sensors may be arranged at a distance from each other that corresponds to a standard parking space size. Thus, advantageously, the size of a free parking space or a distance to the nearest parking vehicle can be measured. For example, a vehicle to be parked when entering the parking area transmits its dimensions to the parking space management system or, alternatively, is measured by a measuring system provided in an entry area of the parking area. Thus, with the available information, it is now possible to find an optimal parking space for the respective vehicle by means of a suitable algorithm and information about the location of the vehicle

assigned parking space, for example in the form of a parking lot ID the

Return the vehicle or the driver to a compatible device. The driver (or the vehicle itself) can now control the assigned parking space.

The system can also be used to detect, after parking, whether the vehicle is optimally parked in the parking space and, if necessary, the adjacent parking spaces to be parked in size for the next

Adapt vehicles.

This results in the advantage that existing parking space can be used more efficiently. The parking area operator can according to the

Bottle consumption even adjust the parking costs.

In a preferred embodiment of the invention sensors are arranged in an entrance area of the parking area, which are designed to measure the vehicle size of an arriving vehicle when entering the parking area and to transmit it to the parking management unit. The transmission can be wireless or wired.

Alternatively or additionally, the parking management unit may be configured to receive information about the size of an incoming vehicle from the vehicle itself. The vehicle thus sends its current dimensions preferably via a wireless data connection to the

Parking management unit.

Additionally or alternatively, the parking management unit may be configured to determine the vehicle type of an arriving vehicle and

Information about the vehicle size depending on the vehicle type from a Query database. The determination of the vehicle type can be done, for example, by comparing camera images with stored images. the

Persons skilled in the art are familiar with other methods of determining the type of vehicle.

In a preferred embodiment of the invention, a plurality of

Parking sensors provided on the parking area, which are arranged in particular at regular intervals from each other.

The parking lot sensors may be recessed into the floor of the parking area or attached to the floor of the parking area. The parking space sensors may be configured as passive sensors (e.g., magnetic field sensors) or as active sensors (e.g., MEMS sensors, radar sensors, or ultrasonic sensors), or may include a combination of active and passive sensor components.

Alternatively, the parking space sensors are arranged above the parking area and designed, for example, as optical sensors or cameras.

In a further preferred embodiment of the invention is the

Parking management unit configured to calculate an optimum route for the vehicle from an entrance of the parking area to the assigned parking lot and to transmit the vehicle. The route information can then advantageously be displayed to the driver so that he can directly control the allocated parking space, or the route information can be used by an autonomous system to control the vehicle autonomously so without the driver's intervention to the assigned parking.

The invention further relates to a method for dynamic

Parking space allocation on a given parking area, wherein by means of at least one parking sensor free and occupied partial areas of the parking area are detected and the size of the free partial areas is detected, and wherein an incoming vehicle depending on the size of the vehicle, a free partial area is allocated as a parking lot. The invention also relates to a computer program which is set up to carry out the method according to the invention. The invention also relates to a machine-readable storage medium on which the computer program is stored.

Short description of the drawing

Embodiments of the invention are illustrated in the drawings and explained in more detail in the following description. It shows:

Figure 1 schematically shows a parking area with one according to a first

Embodiment of the invention trained parking sensor system for dynamic parking allocation;

2 shows schematically a parking area with one according to a second

FIGS. 3A-3C show different situations of parking allocation on the parking area according to FIG. 2.

FIG. 1 shows a parking area 20 with free partial areas 21 and occupied

Partial surfaces 22. About the parking area 20 is a plurality of parking sensors 30 distributed, which are formed free and occupied partial surfaces 21, 22 to detect and detect and to determine their size or dimensions. For this purpose, the parking space sensors in this example are in the bottom of the parking area 20

admitted. The parking lot sensors 30 include passive sensor components (e.g., a magnetic sensor) and active sensor components (e.g., a radar sensor), as well as a wireless communication module

Parking management unit 40. Information is constantly being

For example, at intervals of a few minutes, detected and transmitted to the parking management unit 40. The parking lot sensors 30 may be networked together to facilitate communication. A vehicle 60 travels to an entrance area 25 of the parking area 20. There, data about the size of the vehicle 60 are measured either by means of a corresponding measuring system 35 and to the

Parking management unit 40 transmitted or communicated directly from the vehicle 60 to the parking management unit 40, for example via a wireless data transmission method such. B. WLAN, Bluetooth, GSM.

Depending on the size of the vehicle 60 and the sizes of available free sub-areas 21, the parking management unit allocates a free partial area adapted to its size to the vehicle as parking space 21a. In addition, path information 42 can still be transmitted to the vehicle 60, so that the driver can drive the vehicle 60 in an optimal way to the allocated parking space 21a or the vehicle 60 can independently control the parking space along the path 42, if it is designed accordingly. Thus, the system according to the invention can be advantageously used in a so-called "automatic valet parking" method.

After completion of the particular manual parking operation can be determined by means of the parking lot sensors 30, if the vehicle 60 is optimally in the parking space 21 a and adjust if necessary, the adjacent parking spaces in size for the next parked vehicles.

It is also conceivable that the driver from a distance, z. Example, via the Internet by means of an application on the smartphone or personal computer of the driver, his vehicle 60 indicating the size of the vehicle 60 at the parking management unit 45 and a parking lot 21a is assigned depending on the size of the vehicle. For example, the allocated parking lot 21a may be reserved for against payment of a fee for a certain period of time. When the vehicle 60 approaches the parking area 20, the information about the location of the assigned parking space 21a, e.g. B. on his smartphone or a display of his vehicle, communicated, so that the driver can navigate to the assigned parking lot 21 a.

In the embodiment of the invention of Figure 2, a parking area 120 is shown, which is formed as a parking bay next to a road 110. In At regular intervals, parking sensors 130 are arranged on the parking area 120, which are designed to detect free and occupied partial areas of the parking area 120 and to detect the size of the free partial areas. A parking management unit 140 is provided, which is designed

To receive information about the size and location of free sub-areas of the parking lot sensors 130 and assign an open area as a parking lot depending on the size of the vehicle to an arriving vehicle.

In FIGS. 3A, 3B and 3C, the parking area 120 and the parking sensor system for dynamic parking allocation according to FIG. 2 are shown in various possible occupancy states.

In the situation illustrated in FIG. 3A, the parking area 120 is occupied by three differently sized vehicles 162, 164, 166. This leaves a free partial surface 121. The parking space sensors 130 detect the free partial surface 121 and determine its dimensions. This information is wirelessly sent to the

Parking management unit 140 sent. An incoming vehicle 160, in this example a small car, transmits its size to the parking management unit 140 via a wireless data link. The latter recognizes that the size of the free partial area 121 makes it possible to park the incoming vehicle 160 and divides the free partial area 121 into the vehicle 160 Parking too. The vehicle 160 is also communicated with a route information 142 which guides the vehicle 160 to the allocated parking space. A subsequently arriving vehicle 165, in this example a sedan, also transmits its size to the computer via a wireless data link

Parking management unit 140. This recognizes that there is no more free partial area on the parking area 120 that allows the parking of the vehicle 165 and passes this information to the vehicle 165 on.

In the situation illustrated in FIG. 3B, the parking area 120 is likewise occupied by three differently sized vehicles 162, 164, 166. This leaves a free partial surface 121. The parking space sensors 130 detect the free partial surface 121 and determine its dimensions. This information is wirelessly sent to the

Parking management unit 140 sent. An incoming vehicle 165, in this example a sedan, transmits its size by means of a wireless Data link to the parking management unit 140. This recognizes that the size of the free partial area 121 allows a parking of the incoming vehicle 165 and divides the free partial area 121 of the vehicle 165 as a parking lot. The vehicle 165 is also sent a route information 142, which leads the vehicle 160 to the allocated parking space. A subsequently arriving vehicle 165, in this example a small car, also transmits its size to the computer via a wireless data link

Parking management unit 140. This recognizes that there is no more free partial area on the parking area 120 that allows the parking of the vehicle 160 and passes this information to the vehicle 160 on.

In the situation illustrated in FIG. 3C, the parking area 120 is occupied by three large vehicles 162, 164, 166. There are no free partial surfaces that would allow the parking of a motor vehicle. The parking lot sensors 130 recognize that there are no free partial surfaces. This information is wirelessly sent to the parking management unit 140. An incoming vehicle 165, in this example a sedan, transmits its size to the parking management unit 140 via a wireless data link. This transmits to the vehicle 165 the information that there is no free parking space. The subsequently arriving vehicle 160, also gets the information that there is no free parking space.
