For example, motion information for when the vehicle is parked and when it leaves the vehicle may be applied to the motion pattern.

The travel path arrow 241 may be displayed far or near so that the user can estimate the distance from the current vehicle location to the expected parking location.

The following describes other specific embodiments for estimating a planned parking position of a vehicle. As described above, the collection unit 210 collects motion information from the LED lighting unit 100, wherein the motion information is a plurality of LED lights through motion detection sensors installed in a plurality of LED lights. The information that controls on / off / dimming is collectively.

The on / off / dimming usage information of the plurality of LED lights and vehicle entry / exit information of the corresponding parking lot (for example, information on how many units entered during the unit time, and how many units exited) are managed for a given period of time. Collected through a control server, and the calculation unit 220 applies the parking position estimation method to be described later to the collected motion information and the vehicle entry / exit information, thereby probably estimating a scheduled parking position and providing it to the user You can.

The following are examples of the method for estimating the parking available location.

First, let's assume that the location estimation algorithm is very simple to apply on / off / dimming information of a light including one motion detection sensor and one parking spot.

In this case, the on / off signal of the corresponding lighting is assumed to be an even number of times (for example, 2 times, since on / off is performed by pairing, it is assumed that it is 1 time. That is, the story of number 2 is turned on and off twice). Suppose that the server is provided, and the vehicle entry / exit information is also provided to the control server even number (for example, entry number 1, entry number 2). In this case, it is highly likely that the single parking space is empty.

On the other hand, when the on / off signal of the corresponding lighting is an odd number, and the vehicle entry / exit information is provided to the odd number control server, there is a high probability that the vehicle is occupied in the one parking lot.

In another case, the total number of on / open times of the corresponding lighting and the total entry / exit information of the vehicle do not match. In this case, it is assumed that a relatively accurate vehicle total entry / exit information is trusted, while it can be estimated that there is an error due to noise during the total number of on / open times of the corresponding light. Therefore, for example, when the total entry / exit information of the vehicle is an even number or the total number of on / open times of the lighting is odd, the vehicle parking seat is likely to be empty.

In reality, a parking lot consisting of only one parking spot and one lighting may be formed in a single-family house or the like, and may be applied to a special type of parking spot such as a parking spot for charging an electric vehicle, so the above-described parking is possible. The possible location estimation algorithm can be used in this case to effectively use the parking location estimation.

Let's expand the parking spot and lighting mentioned above to multiple.

First, it is possible to estimate that all parking spaces can be parked if the number of cars entering and leaving the vehicle is the same during the unit time after initialization (there is no remaining parking number).

Secondly, during the unit time, if the amount of entry is greater than the amount of exit, that is, if there is a vehicle remaining in the parking lot, the vehicle is placed in the parking lot as much as the difference between the amount of entry and exit (defined as the gap between the exits and exits). It can be estimated that the total number of parking spaces minus the gap between entering and exiting cars is the number of available parking spaces.

Third, if the number of on / offs during the unit time of the target light located at the target parking position to check whether parking is possible is odd, immediately check the number of on / offs of the adjacent lights, and turn on / off the adjacent lights. If the number of times is the same number (odd) as the number of on / off times of the target lighting, it is estimated that all vehicles have passed the target parking spot, and thus the target parking spot is empty and parking can be estimated. On the other hand, if the number of on / offs of the adjacent lights is smaller than the number of on / offs of the target lights, it can be estimated that the vehicle is parked in the target parking space.

Fourth, the number of on / offs during the unit time of the target light located at the target parking position to check whether parking is possible is an even number, and the number of on / offs of adjacent adjacent lights is equal to the number of on / offs of the target light ( Even number), it can be estimated that a vehicle corresponding to a number less than half of the even numbered vehicle parks at the target parking lot and then leaves the vehicle or passes the target parking lot as much as the vehicle corresponding to the even number. In any case, it can be assumed that the target parking space is empty and parking is possible. On the other hand, if the number of on / off times of the adjacent light is smaller than the number of times of on / off of the target light, it can be estimated that the vehicle is parked in an adjacent parking place corresponding to the adjacent light.

Fifth, if the above-described method of estimating the target and adjacent parking spots and lights is regressively extended to adjacent parking spots and lighting spots and lights again adjacent to the parking spots, whether parking is possible for all parking spots eventually Estimate of becomes possible.

In this case, an algorithm for providing an index of the likelihood of parking available location may be roughly presented as follows.

(Where # denotes the number of times, n denotes the total number of parking digits, k denotes the k-th target parking digit, and Function denotes a function reflecting the above five estimation methods.)

If the corresponding probability index is large, it means that the target parking spot having a larger value has a higher parking probability (the parking space is empty) than the comparison parking spot having a smaller value.

In addition, although it is not mentioned here to randomize it, it may be used as a probability through normalization as a sum of the total probability index.

As a result, through the implementation of this method, the planned parking position of the present invention does not attach an additional sensor such as a separate camera module to the conventional lighting, but motion information using a conventional motion detection sensor (light on / off and dimming sensing values). Using this, and applying the above-described parking location estimation algorithm, it is possible to provide a parking vehicle scheduled location where new vehicles can be parked. In addition, by providing the information online to an external navigation service provider, the service provider uses this information to provide users with a parking space available to users who set the parking lot as a destination, thereby providing the service provider. It allows them to provide users with information related to where they can park their vehicles without investing in infrastructure.

Although described above with reference to preferred embodiments of the present invention, those skilled in the art variously modify and change the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. You can understand that you can.
