Description

Parking route guidance system for electric vehicles {System for route guidance for electric vehicle}

The present invention relates to electrical installations of buildings. More specifically, it relates to a parking route guidance system for guiding a route to a parking space in which a charging control device is installed for an electric vehicle among vehicles entering a parking lot of an apartment building.

In recent years, the development and supply of eco-friendly vehicles are gradually spreading in countries around the world in accordance with the strengthening of global environmental regulations and the trend of energy saving.

An eco-friendly vehicle may include a hybrid vehicle, a hydrogen vehicle, and an electric vehicle that use both an electric motor and a gasoline engine.

Among them, an electric vehicle refers to a vehicle driven by rotating a motor only with electric energy stored in a battery without using petroleum fuel.

Since the electric vehicle does not emit exhaust gas, it does not cause environmental pollution, and since it can be operated only with electricity, compared to gasoline fuel, the cost of vehicle operation is relatively low.

However, since the distance that an electric vehicle can travel on a single charge is limited compared to a gasoline vehicle, it not only requires frequent charging, but also has a problem of lack of charging infrastructure for charging.

On the other hand, an apartment house is a type of housing in which a plurality of households or a plurality of households co-occupy in one building.

Multi-unit dwellings are obliged to build a charging system dedicated to electric vehicles for the use of electric vehicles in each household. Recently, there is a tendency to increase the mandatory installation rate of charging systems exclusively for electric vehicles with respect to newly built apartment houses.

However, in order to add an electric vehicle-only charging system to an apartment building, it is necessary to consider the load of the entire building, the currently available power capacity, and the expected load according to the operation of the electric vehicle-only charging system.

Therefore, there is a need for research on the efficient operation of a charging system dedicated to electric vehicles in multi-unit dwellings.

In addition, since the apartment house has a limited parking space exclusively for electric vehicles installed in a wide parking space, there is a problem in that it is not easy for a driver driving an electric vehicle to enter the parking lot and recognize the location of a parking space exclusively for electric vehicles.

While turning on the guidance light located in the electric vehicle, the guidance light located in front of the electric vehicle on the route is turned on according to the movement of the electric vehicle, and the lighted guidance light may be turned off when the electric vehicle passes.

In addition, the route guidance unit 530 turns on a guide light on the route when two vehicles are continuously detected by the vehicle detection device 200 within a predetermined time interval and both continuously detected vehicles are identified as electric vehicles. The charging control device 100 may be respectively guided to the moving path to the parking space installed. Here, the route guidance unit 530 may change the color of guidance lights that are turned on in each of the consecutively sensed routes of the two vehicles.

In addition, the route guidance unit 530 may identify one household entrance estimated to be headed by a vehicle occupant among a plurality of household entrances existing in a parking lot based on the extracted vehicle number of the license plate. That is, the route guidance unit 530 may extract the unit number of the household in which the vehicle driver resides based on the vehicle number, and identify a household entrance and exit through the corresponding unit number based on the extracted unit number. In addition, the route guidance unit 530 identifies a parking space that is the shortest distance from the identified household entrance among vacant parking spaces in which the charging control device 100 is installed, and guides a route to the identified parking space. can do.
