Abstract

The invention relates to a method for recognizing the freeing of a parking space (21-26), wherein the motion profile of a driver (1-6) of a vehicle (11-16) parked in the parking space (21-26), who is moving outside of the vehicle (11-16), for example on foot, is continuously sensed and evaluated. The probability of the freeing of the parking space (21-26) within a defined time span is calculated on the basis of the motion profile of the driver (1-6) thus sensed and is provided in such a way that said probability can be retrieved.

Description title

Method for detecting the release of a parking space Prior art

It is known in parking lots or parking garages optically provide an indication that indicates where parking is still free. This information can also be displayed by means of a smartphone app.

If a driver of a vehicle looking for a parking space, a pitch is displayed as free, he will make his way to this pitch. If this takes a certain amount of time and the demand for parking spaces is greater than the supply at the moment, the parking space will become high

Probability to be forgiven again.

From US 2008048885 A a system and method for recording usage data for a plurality of parking lots is known. The usage data is used to calculate the probability of availability of a particular pitch as a function of time. The resulting probability can be combined with availability data to one

End user who is looking for a parking space. This information may be combined with the user's estimated time of arrival (ETA) to assist the user in selecting a parking space. The usage data are thereby recorded by occupancy sensors or manually over a longer period of time and an occupancy probability e.g. depending on the day of the week, the time of day, the weather or a specific event.

Disclosure of the invention The object of the invention is to predict which parking lots will be released in the next time with high probability. This facilitates the search for a vacant parking space in the future.

This is done by information about the probability that

Parking spaces become available within a certain or predetermined period of time. It is proposed a method for detecting the release of a parking space, wherein the movement profile of a driver on the

Pitch parked vehicle, located outside the vehicle

for example, walking, continuously recorded and evaluated. A probability of freeing the parking space within a predetermined period of time is calculated based on the thus detected movement profile of the driver and made available retrievable.

Such a method can be used, for example, by a parking lot operator or department store operator to provide information as to which parking space is cleared when and with what probability. With a suitable

Algorithm is calculated which parking in the parking garage with high

Probability in a given period of time, e.g. in the next 5 - 15 minutes, free. This information is kept up to date. A prerequisite for the efficient functioning of the invention

Procedure is that the driver (s) of the parked vehicle (s) allow their movement data to be collected and used to calculate the likelihood of their parking space being released. Preferably, any driver who wants to use the process itself, to

To obtain information about a likelihood of getting rid of a parking space within a predetermined period of time, commit himself, after parking his vehicle to record his own movement profile in order to calculate again the probability that the occupied by his vehicle parking space within a predetermined period of time is free again , Advantageously, the number of users and the number of predictable Parking spaces, ie the parking spaces for which information about the probability of being released within a certain period of time is available, are increased in the parking garage / parking space.

In particular, the probability of a release of the parking space is increased when the driver approaches the parking space, in particular during several consecutive measurement cycles of the position determination.

For example, the probability is increased by 10% when the driver has moved towards his vehicle in two consecutive measurement cycles of the position determination.

In particular, the probability of a release of the parking space is reduced when the driver moves away from the parking space, in particular during a plurality of successive measuring cycles of the position determination. For example, the likelihood is reduced by 10% when the driver has moved away from his vehicle in two consecutive measurement cycles of positioning.

In a preferred embodiment of the invention, the probability of becoming vacant of a parking space is calculated in each case for a plurality of parking spaces and made available retrievably. Thus, for example, a map of the parking space (for example of a parking garage) can be created, whereby a respective number of parking spaces, ideally all parking spaces, can be created

Probability is shown that this space is free or free within a predetermined period of time. In this case, the time period can be selected by a user, or the time period is automatically selected depending on an estimated arrival time of the user.

The motion profile of a driver of a parked vehicle is preferably detected by a mobile device carried by the driver in FIG

periodically the position, in particular in the form of GPS coordinates, the driver is determined. The regular intervals can be, for example, 30 seconds. The parking space searching user can now get the information about the

Probability that a parking space will become vacant at a defined time and / or within a predetermined period of time, e.g. in form of a

View the pitch card and display it on your mobile device. It can e.g. the probabilities of getting rid of different parking spaces are displayed. On the one hand, the user can display this information for each parking space individually, but also summed up for individual paths in the parking space system. Through a display for individual paths in the parking space system summed display, he can learn how he has to drive, so that he overall

probably has the shortest wait time. Other participating vehicles that are already in waiting mode can also be considered here. This information can also be transferred to a navigation system for navigation, for example to the parking space with the highest probability.

According to a second aspect of the invention, a system for detecting the release of a parking space is proposed, which is a

Data processing device which is designed to receive and evaluate motion profiles of drivers of parked vehicles. An algorithm is carried out on the data processing device, wherein the algorithm provides a probability of a release of the algorithm

Pitch, in particular within a predetermined period, is calculated based on the motion profile. The system also includes a communication unit which is configured, the probability of freeing the parking space to a central server and / or to a

Mobile device and / or to a communication unit of a vehicle to send.

Preferably, the probability of getting rid of a parking space is calculated in each case for a plurality of parking lots.

The exchange and the provision of information about the

Likelihood of a vacancy of a parking space is preferably done by a server (or cloud server) on the converge the information of the participants. On the server can also the creation and evaluation of motion profiles and the resulting calculation of the

Probable release of a parking space done. Brief description of the drawings

Figure 1 shows schematically a situation according to an embodiment of the invention

FIG. 2 shows a flow chart of a method according to the invention

FIG. 1 schematically shows a parking lot 10 of a shopping center 20 with several parking spaces 21-26. Plots 21-26 are all occupied by vehicles 11-16. According to one embodiment of the invention, an assignment of each driver 1-6 to a parked vehicle 11-16 is known. The drivers 1-6 move in the vicinity of the parking lot 10 or

Department Store 20. The assignment is made via a mobile device, such as a mobile phone of each driver. The mobile device determines coordinates, e.g. GPS data at regular intervals, allowing you to record and analyze the movements of the driver in the store. Thus, a motion profile of the driver is created. Now, for example, it is determined in each case at a time interval of 30 seconds whether the driver has moved continuously, that is, over several consecutive measurements, in the direction of his vehicle. When the driver approaches his vehicle at several measuring intervals, an increasing probability, e.g. + 10%, assuming that the parking space assigned to this driver will be vacated at a defined time and / or within a predetermined period of time. Of the

Probable time of release can also be calculated, for example, from the average walking speed of the driver and the current distance to the vehicle. If he moves away from his vehicle, the probability of being released decreases accordingly.

An initial probability of getting rid of a parking space 21-26 can be calculated, for example, from an average parking duration, which can be determined, for example, once by observing the parking space over a longer period of time. The average parking time of a particular driver can alternatively or additionally also from his behavior in the past, ie in particular from its motion profiles determined in the past for the same parking lot.

In the illustrated example, the driver 3 moves in the direction of his vehicle 13. The detected movement profile of the driver 3 shows that the driver 3 has been moving towards his vehicle 13 for several measuring cycles. As a result, the likelihood of freeing the pitch 23 is further increased.

For example, a maximum probability of being released may be 90% in 10s if the temporal resolution of the motion profile is 10s.

A higher probability is not meaningful in this case, since the driver 3 can reverse at any time within the next 10s measurement interval. One possibility, however, of indicating the probability higher is that the driver 3 is active, e.g. by means of his

Mobile device communicates that he wants to leave immediately.

In the example shown, the driver 5 moves away from his vehicle 15. The detected movement profile of the driver 5 shows that the driver 5 has been away from his vehicle 15 for several measuring cycles. As a result, the likelihood of freeing the pitch 25 is further reduced.

The minimum departure probability may be, for example, 0% in 5 minutes, in case the driver 5 can not reach his vehicle 15 by walking in his average walking speed at this time, or if he continuously moves away from the parking space of his vehicle.

Driver 2 has just left shopping mall 20 and will move towards his vehicle 12. The probability of the release of the

Pitch 22 will rise so.

The drivers 1, 4 and 6 stop according to their movement profile within the shopping center 20. Their respective distance to their vehicles 11, 14 and 16 will not change significantly on average over several measuring cycles. The respective probability of release of the parking spaces 21, 24 and 26 is determined by a previously determined average residence time of individual driver 1, 4 and 6 in the shopping center 20 or averaged over several users average length of stay.

The exact staggering of the probability can preferably be determined by analyzing the past behavior of the participants.

FIG. 2 schematically illustrates the sequence of a method according to the invention. In the first step 100, a driver 1 places his vehicle 11 on a parking space 21 and leaves the vehicle 11. The driver activates the creation of his movement profile on his mobile device.

In step 200, the mobile device of the driver 1 detects the position of the driver 1 at regular intervals and transmits them to a central location

Data processing device 30.

In step 300, a current movement profile of the driver 1 is created and evaluated from the position data, wherein a probability of a

Freeing the parking space 21 is calculated at a defined time and / or within a predetermined period of time based on the motion profile.

In step 400, the likelihood of the parking space 21 becoming available at a defined time and / or within a predetermined period of time is made available to parking-seeking users.
