Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a parking lot guidance device that directs and guides you to a parking lot in such a way that the time it takes from arriving at the parking lot to parking is the shortest. It is related to.

(Prior art) Devices that guide cars to parking lots using display devices installed in dispersed locations have conventionally displayed only information on the degree of congestion (vacant, full, etc.) for each parking lot itself, and drivers have There is a parking lot to choose from.

(Problems to be Solved by the Invention) According to the above-mentioned conventional technology, the parking lot guidance device allows the driver to avoid a full parking lot and head toward an empty parking lot.

However, even if an empty parking lot is confirmed on the display device, the road leading to the parking lot may be congested, impassable for some reason, or far away.

The time it takes to park is the sum of the time it takes to arrive at the parking lot and the waiting time from when you arrive at the parking lot until you enter the parking lot, so the parking lot you choose is simply based on the availability of the parking lot. It cannot be said that this is the fastest parking lot.

For example, if the driving time is 15 minutes to Parking Lot A, where there are empty cars and no waiting time, and the driving time is 5 minutes to Parking Lot B, which is full and has a waiting time of 5 minutes. If you choose this option, you will be able to park faster as a result.

With the above-mentioned conventional technology, it is not possible to select a parking lot after considering the time required until the vehicle can actually park.

The present invention displays the time required from the point where the display device is installed to when you can actually park your car in each parking lot, taking into account road congestion conditions, etc., thereby allowing parking lot users to make the correct choice and improving serviceability. The purpose is to provide a rational parking lot guidance device.

[Structure of the invention]

(Means and effects for solving the problem) In order to solve the above-mentioned problems in the prior art, the parking lot guidance device of the present invention includes means for inputting parking lot vacancy information and waiting information, A means for inputting traffic information on roads around the parking lot, a calculation means for calculating the parking lot where you can park in the shortest time from this input information, and a calculation means installed near the roads around the parking lot to calculate the time required to park. The calculation means inputs information on the parking lot's empty status and waiting state, as well as traffic information on roads near the parking lot, and displays the data from the distributed display devices to the parking lot. The time required to park the vehicle is calculated, and this time is displayed on each display device to inform the driver of the parking lot where the vehicle can be parked in the shortest possible time.

(Embodiment) An embodiment of the parking lot guiding device according to the present invention is shown in FIG.

As shown in FIG. 1, a parking lot guiding device according to the present invention includes:
Parking information input source 10. It is composed of a traffic information input source 2o, a central control device 30, and a display device 40, and further includes a central control device! 30 is an input section 31. Inference section 32, output section 33. It consists of a knowledge base 34, a parking lot database 35, a display device 36, and a keyboard 37.

The parking lot information input source 10 inputs the vacancy status information (full, number of vacancies, end, etc.) and waiting status information (waiting time until parking if full) of each parking lot to the central control device 30.

In addition, the traffic information input source 20 includes traffic congestion information (congestion distance from each intersection, etc.) on roads surrounding each parking lot and traffic regulation information (
Temporary traffic restrictions due to 9 construction events, etc.) will be handled by the central control bag [
Enter 30.

The parking lot information input source 10 and the central control device 30, the traffic information input source 20 and the central control device 30, and the central control device 30 and the display bag [40] are connected by wireless or wired communication means. ing.

Further, instead of directly connecting the parking lot information input source 10 and the traffic information input source 20 to the central control device 30, all or part of the information may be input via the keyboard 37.

An example of the processing contents of the central control device 30 is shown in FIG.

In FIG. 2, first, the input unit 31 inputs information on N parking lots via communication means or the keyboard 37.
TI), if the parking lot is open (Sr1), enter the number of vacant spaces in the parking lot (5T3), and input the parking waiting time for the parking lot (Sr4).

Next, the input unit 31 inputs traffic information on roads around the parking lot via the communication means or the keyboard 37 (5T5), and stores this information in the parking lot database 35.

Next, the inference unit 32 performs inference using the inference rules in the knowledge base 34 and the information in the parking lot database 35,
The time required for each display device to be parked in each parking lot is calculated (Sr1).

The knowledge base 34 stores rules for calculating the time required to park in each parking lot for each display device based on input information from the parking lot information input source 10 and input information from the traffic information input source 20. ing.

These rules are written in the form of IF (condition part) and THEN (execution part), and the condition part describes various states based on combinations of parking lot information and traffic information. In addition, the execution part has the state of each condition part.

A formula for calculating the time required from each display device to be able to park in each parking lot, or an intermediate state used to calculate the time required from each display device to be able to park in each parking lot is described.
