Locating a Vehicle The present invention relates to a system for locating a vehicle. Moreover, the present invention relates to a corresponding method for such

Positioning. A vehicle is here understood to mean any mobility device with which a transmitter or receiver can be moved within a predetermined range. In particular, it may be a motor vehicle.

A parked automobile or motor vehicle,

Bicycle or other vehicle in z. As a parking garage or in a street of a city can be a major problem, if you do not remember where the vehicle was parked. In parking garages, for example, you may not be able to get to the floor and the

Remember parking lot number, and in inner cities you often lose track of which street you have parked in.

A common locating technology is the use of beacons or tracking devices, for example, in a

Lamp to be installed. This can be used to orient or locate a smartphone with the sensors available to it. In addition, the location data can also be evaluated by a server to which the smartphone has to log on to implement location services.

In addition, so-called "Locator Nodes" are known, which are router-like boxes that detect the presence and approximate position of smartphones via a WiFi receiver.The object of the present invention is to be able to reliably detect the position of a vehicle in a predetermined range , According to the invention this object is achieved by a system according to claim 1 or 7 and a method according to claim 16 or 17. Advantageous developments of the invention will become apparent from the dependent claims.

According to the invention, therefore, a system is provided for

Locating a vehicle,

full

- the vehicle, where

the vehicle is assigned a transmitter with which an identification signal can be radiated wirelessly,

a lighting device for illuminating a vehicle drivable area with a predetermined position, wherein

- The illumination device, a receiver for receiving the identification signal and

an interface for providing a locating signal with transmitter identification data from the

Identification signal and with illumination position data or illumination identification data from the

Having lighting device,

a communication network for transmitting the locating signal of the interface and

a data processing device connected to the

Communication network is connected to winning one

Position information regarding the vehicle from the locating signal.

Advantageously, the vehicle is located indirectly via a transmitter in or on the vehicle. This is done by exploiting at least one illumination device whose position is known. If the illumination device receives the signal from the vehicle, this is an indication that the transmitter is located near the illumination device. Since the transmitter is assigned to the vehicle, it is possible indirectly to obtain position information about the vehicle via the identification data of the transmitter. Preferably, the locating signal contains the

Lighting identification data from the

Lighting device, and the

Data processing device is designed to use an assignment table from the

Lighting identification data of the lighting device to determine lighting position data to win with them the position information relating to the vehicle. Thus it is sufficient if the position data of the

Lighting device centrally in one

Data processing device are deposited.

The transmitter of the vehicle may be formed as a transceiver unit to transmit signals from the

Data processing device or a cloud, in particular the position information to receive, and the receiver of the illumination device may be formed as a transceiver unit to send signals. This would ensure a return channel with which the vehicle or the receiver arranged there can receive the position information from the data processing device.

The transmitter may be integrated in a mobile communication device or fixed in the vehicle. For example, the transmitter part of a mobile phone or

Smartphones or a portable computer. This mobile communication device is then stored, for example, in the vehicle and moved by this. If the transmitter is integrated directly into the vehicle, the transmitter always automatically moves with the vehicle.

According to a further embodiment of the

Communication network connected several lighting devices of the type mentioned, and of at least two of the

Lighting devices are a respective locating signal with respect to the one vehicle to the

Data processing device transmissible, and of the Data processing device is a geometric

Emphasis from the data of the locating signals as

Position information can be determined with respect to the vehicle. In this way you can adjust the position of the transmitter

or vehicle based on several involved

Better determine lighting equipment.

In addition, the data processing device may be designed to repeatedly determine the position information and to trigger a current position information triggered by falling below a predetermined speed of the transmitter and / or to send this.

This makes it possible, for example, that the position of the transmitter, which is moved by the vehicle, only store or transmit to the transmitter or the vehicle when the vehicle only

Walking speed or less. This is

if applicable, a sign that the vehicle is occupying a parking position.

According to the invention, the above object is also achieved by a system for locating a vehicle, comprising

- the vehicle, where

the vehicle has a receiver with which a position-determining signal can be received wirelessly,

- A lighting device with a predetermined position for illuminating an accessible area of the vehicle, wherein

- The lighting device, a transmitter for transmitting the position determination signal and

- the vehicle or the receiver one

Data processing device for obtaining a

Position information regarding the vehicle from the

Positioning signal has.

Advantageously, the vehicle here does not necessarily have a transmitter, but a receiver. This receiver can be used wirelessly Receive position determination signal, which either directly position data or at least

Contains identification data of the lighting device in the vicinity. A data processing device of the receiver z. B. in or on the vehicle can then from this position determination signal position information

win with respect to the lighting device. This allows the vehicle at least roughly the position of

Lighting device to be assigned.

If the position determination signal is not directly the

Position data of the lighting device, but only illumination identification data, the vehicle or the receiver must have assignment information in order to obtain the position information with respect to the

Vehicle from the lighting identification data

To determine illumination position data for the illumination device. For example, are appropriate

Installation data stored in an app of a smartphone, because even here, the recipient can be, for example, a mobile communication device. Alternatively, of course, here also the receiver can be firmly integrated into the vehicle.

Optionally, a signal strength of the receiver may be provided by the receiver

Identification signal measurable from the interface, a corresponding signal strength value in the locating signal

can be integrated and usable by the data processing device, the signal strength value for obtaining the position information with respect to the object. By exploiting the signal strength when receiving the location can be significantly refined. In addition, a plurality of illumination devices can also be provided in this system in order, if appropriate, to again estimate a geometric center of gravity as estimated

Determine position of the vehicle and thereby refine the location.

Moreover, it is also advantageous in this system, in which the receiver is arranged on the vehicle side, if _r

the data processing device is configured on the receiver side to repeatedly determine the position information and to store a current position information triggered by a falling below a predetermined speed of the receiver. Again, it can also be provided here that the position on the smartphone is displayed only when the vehicle is moving at walking speed or less. The given speed does not have to be the walking speed, but can also mean any other speed threshold.

Data transmission between the transmitter and the receiver may be via Bluetooth technology, WiFi technology, RFID technology or light-based transmission technology. In principle, an acoustic would also be

Data transmission possible. However, it is advantageous if standardized protocols are used.

In a further advantageous embodiment, the receiver or the transmitter have the

Lighting device and the lighting device itself a common power supply. Thus, for the location or position determination of the infrastructure of the lighting device or the

Lighting system can be used.

To solve the above problem is also provided

Method for locating a vehicle, by

wirelessly transmitting an identification signal directly from the vehicle or from a location located in

given a local relationship with the vehicle,

- Receiving the identification signal by a

Lighting device with predetermined position and

Sending a locating signal with transmitter identification data from the identification signal and with

Lighting position data or

Lighting identification data from the Lighting device via a communication network to a data processing device,

Obtaining position information regarding the

Vehicle from the locating signal through the

Data processing device.

Similarly, the above object is achieved with a method for

Locating a vehicle, through

- Wireless transmission of a position determination signal from a lighting device with a predetermined position for illuminating a vehicle passable by the vehicle

Area, and

Receiving the position determination signal by a

Receiver in or on the vehicle,

Obtaining position information regarding the

Vehicle from the position determination signal by the vehicle or the receiver. The methods may be triggered by moving the receiver from the drivable area into an area not accessible by the vehicle (e.g., staircase). The receiver should also be accessible there from a lighting device.

As described above in connection with the various systems functional features can also be used for

Development of the inventive method with

serve corresponding process characteristics.

The present invention will now be explained in more detail with reference to the accompanying drawings, in which:

Fig. 1 shows a scenario with a vehicle, wherein a

Smartphone serves as a transceiver for locating; Fig. 2 is a similar scenario as in Fig. 1, but wherein the smartphone layout information on the

Environment receives; Fig. 3 shows a scenario in a parking garage, wherein the

Vehicle speed is reduced;

Fig. 4 shows a scenario in a parking garage, wherein a

Smartphone directly from a lighting device receives an identification number by means of light;

Fig. 5 is a scenario similar to that in Fig. 1, wherein the

Vehicle has an ID transmitter; and FIG. 6 is a scenario similar to FIG. 3, where FIG

Vehicle or a lying in it

Smartphone sends an ID radio signal.

The embodiments described in more detail below represent preferred embodiments of the present invention

It should be noted that the individual features can be realized not only in the described combinations, but also in isolation or in other technically meaningful combinations.

An exemplary system according to FIG. 1 has

Mobility device or vehicle 1, of which in FIG. 1, only the dashboard and the steering wheel are indicated. In addition, the system includes a mobile terminal 2, which is for example a

Smartphone can act, which is placed in the vehicle. An area drivable by the vehicle (eg road, sidewalk, parking garage or the like) is with

Lighting devices 3 illuminated. These

Lighting devices 3 are immobile or localized. Their respective position is given

or known. In the case of FIG. 1, the vehicle 1 optionally travels to a parking garage 5 on a road 4. Each or at least some of the lighting devices 3 on the road or in the parking garage 5 are each equipped with a transmitter 6. Such a transmitter may, for example, be a radio transmitter or the lamp of the illumination device 3, which emits an identification signal by means of light modulation. The mobile terminal 2 in or on the vehicle receives such

Positioning signals. These include in one case direct position data from the respective transmitter, so that the mobile terminal 2 can determine its position by being in the vicinity of the respective illumination device 3.

Optionally, the data processing device of the mobile terminal 2 or the receiver is also able to own position from the signals of several lighting devices 3, for example by means of

calculate geometric center of gravity.

The recipient may not only be a smartphone, but generally, for example, a Bluetooth, WiFi- or RFID receiver. Optionally, the receiver may also include a light sensor such as a camera or a simple brightness sensor or the like to receive a modulated light signal. With regard to the method, for example, the mobile terminal 2 (eg smartphone) moves with the aid of the vehicle 1 in an area of one or more luminaires or lighting devices 3. One or more of the

Illuminators 3 wirelessly transmit

Positioning signal from, with the receiver, here the smartphone his position or that of the

Vehicle should calculate. For this purpose, the smartphone receives the position-determining signal and wins it 0

Position information. Thus, for example, directly coordinates can be output with respect to the position of the vehicle on the smartphone. This can be the

Vehicle or the mobile terminal 2 locate themselves.

A variant of the locating system of Fig. 1 is shown in Fig. 2. Again, the vehicle 1 drives to the

Street 4 lighting equipment 3 over. In the street 4 parking bays 7 are provided. The vehicle 1 wants to park, for example, in one of the parking bays 7 and the position should be recorded. The mobile terminal 2 is located in the vehicle 1 or on a bicycle or the like, ie in fixed local relationship to the vehicle. It receives, for example, the

Identification numbers of the individual

Lighting devices 3. Thus, for example, by means of map information, the current location of the vehicle or mobile terminal 2 or receiver can be determined. Such map information can be received by the mobile terminal 2, for example, from a cloud 8 transmitted via UMTS or 3G.

This map information includes the positions of the individual lighting devices 3, which can be deduced on the own position of the vehicle. The

Data processing device of the mobile terminal 2 accesses this layout information but also, for example, therefore, to a corresponding graph on the screen of the mobile terminal 2 of FIG. 2 on the local

Environment of the vehicle. Over a

Time series analysis, the mobile terminal 2 or a service for the device now derive how fast the vehicle 1 moves. For example, as long as the speed is above walking speed, it is inferred that the vehicle 1 is not yet parked.

According to a special variant, it is in the

Receiver of the lighting devices 3 emitted position determination signal not to a mobile terminal, but to a receiver integrated into the vehicle. So that can virtually the vehicle itself

Determine location. In this case, for example, a smartphone could ask for this information about the location of the vehicle.

FIG. 3 shows a scenario in a parking garage. The vehicle 1 drives with slower and slower

Speed into the parking garage until it finally stops in a parking position. On the ceiling 9 of the parking garage numerous lighting devices 3 (eg ceiling lights) are provided. Preferably, the lighting devices are distributed homogeneously in the parking garage area. Each or at least several of the lighting devices 3 has a transmitter Sl, S2, S3, Sn. This may, for example, be a beacon as a radio transmitter or another transmitter, possibly the lamp itself. Each transmitter S1 to Sn transmits a positioning signal 10 received by the receiver (eg, the mobile terminal in the vehicle 1 or receivers integrated therein). Using a layout plan stored in a database, for example B. is deposited in the cloud 8, the vehicle 1 can locate itself in the parking garage. Is now, for example, the speed of the vehicle 1 and thus that of the receiver located therein or on z. B. walking speed (for example, 5

Kilometers per hour), the current position is stored in the mobile terminal 2, in the vehicle 1 and / or in the cloud 8. If appropriate, it is output on the mobile terminal 2 as text or graphically. This saving or output is thus triggered when the speed of the vehicle falls below a predetermined threshold. According to another variant, the storing or displaying of a possible location of the vehicle is triggered by the fact that the mobile terminal 2 completely stops or one for the

Vehicle 1 inaccessible place, z. B. reaches a staircase 11. This would be an indication that, for example 2

the driver with the mobile terminal 2 has left the vehicle and the vehicle is now in close proximity in a parking position. In this case, for example, the last possible parking position can be stored. As a further variant, it would be conceivable for a user to enter his smartphone directly after parking, that he / she would be able to log in at this location which was detected, for B. under a lamp with a

certain signal, parked. The data processing can reproduce this location in a map / logic.

The speed of the vehicle can also be communicated by the latter itself to the mobile terminal, and the location triggered in dependence thereon. In addition, the speed of the vehicle can also be

for example, via the signal strength of

Determine position determination signals 10.

4 shows an alternative scenario in a parking garage. Each individual parking bay 12 is on the ceiling with a

separate lighting device 3 equipped.

For example, it is in the

Lighting equipment 3 to LED lights. These not only emit the usual visible light, but the light can be modulated to transmit the position-determining signal 10. This can be, for example, a

Identification number that is unique in the system, for example, transmitted to a mobile terminal 2 having a corresponding light receiver. The driver then holds the mobile after parking his vehicle

Terminal 2 in the light cone of the lamp or lighting device 3, which is arranged in the parking bay 12 of his parking vehicle 1. Thus, the current position of the vehicle 1 can be stored as a parking position. Thus, a position determination without GPS signal 13 is also possible here.

Fig. 5 shows a similar scenario as in Fig. 1 or 2. In this case, however, the vehicle 1 is the sending of a 3

Identification signal 14 off. For this purpose, for example, a transmitter 15 is integrated directly into the vehicle 1. Alternatively, there is a mobile terminal 2 in the vehicle 1, and the mobile terminal 2 sends an identification signal 14, z. For example, a MAC address.

The lighting devices 3 on the road 4 each have a receiver 16. These receivers 16 receive the identification signal 14 as soon as the vehicle 1 is in the respective range. The respective

Lighting device connects the presence information with the identification number (illumination identification data) or with lighting position data of the respective lamp itself and sends a corresponding locating signal with this data by means of a corresponding interface via a communication network to a central

Data processing device. To this

Data processing device, the location of the mobile terminal 2 and the transmitter 15 and thus the location of the vehicle 1 can now be retrieved.

In Fig. 6 is again a scenario in a parking garage

shown. The vehicle 1 drives into the parking garage

decreasing speed until it stops, for example, in a parking bay. The vehicle 1 is equipped with the transmitter 14 or there is a mobile terminal 2 in the vehicle 1. From the vehicle 1 is therefore a

Identification signal 14 off. On the ceiling 9 of the parking garage, homogeneous lighting devices 3 are again preferably arranged, each having a receiver El, E2, E3, En. These are adapted to the identification signal 14 to

detect. All receivers El to En are with a

central data processing device 17 connected. This can, for example, a position information on the

Deposit vehicle 1 in the cloud 8, in which, for example, a layout plan of the lighting devices 3 in 4

Car park is stored. The corresponding

Position information is then again, for example by means of wireless data transmission 18 (eg UMTS / 5G) to the

Vehicle 1 transferable together with the layout plan.

When the vehicle 1 is driven into the parking garage, the radio signal is identified by the individual receivers E1 to En. "Of course, the position signal 14 does not have to be detected or identified by each receiver

Identification signal registered in order to capture the movement profile of the vehicle 1 and its current position more accurately. The corresponding transmitter identification data are combined with lighting position data or

Lighting identification data from the respective ones

Illumination devices 3 are transmitted via the communication network 19 to the central data processing device 17. There, the current position information, i. H. obtained the current position of the vehicle 1 from the locating signal or the locating signals. This position information is then transmitted to the vehicle 1 via the return channel 18, which can alternatively also run via the communications network 19

or the mobile terminal 2 in the vehicle 1 transmitted.

Once again, only a mobile terminal is arranged in or on the vehicle 1, so can via a time series analysis the

Speed of the mobile terminal 2 are detected. As soon as the mobile terminal changes its movement behavior, the current position can be stored as a possible parking position. Likewise, alternatively, the triggering of storing or providing or sending the position information about the vehicle can take place by registering whether the mobile terminal is located at a location inaccessible to the vehicle 1, e.g. B. a staircase 11 with 5

corresponding lights. The last possible parking position is registered and as the most likely parking position z. B. deposited in an app. In the memory or the cloud 8 can also

be deposited, at which point of the area which transmitter would have to be recorded how strong. For this purpose, the area must be run once with a corresponding recorder to record from each point a clear "fingerprint" (which signal strengths of which IDs are to be received at one point?) Are enough lights with beacons installed, very characteristic fingerprints Including the signal strengths can thus take place a refined location.
