Description

    The present invention relates to a guidance display device that facilitates reaching an empty parking space in a self-propelled parking lot.

    In the self-propelled parking lot, as shown in FIG. 1, a plurality of parking spaces 3 are arranged on both sides of the road 2 on which the vehicle 1 travels, and the driver searches for an empty parking space while driving on the road 2. Parked.

    A large-scale parking lot has a structure in which a large number of island-like parking space blocks each composed of two rows of parking spaces are arranged with parking spaces arranged on both sides of a roadway branched from a main road. In general, the roadway is one-way to reduce the risk of traffic accidents.

    In such a large-scale self-propelled parking lot, in order for the driver to park smoothly, it is necessary for the driver to recognize where there is an empty parking space.

    One method is to indicate whether there is an empty space in the area or whether the area is full. However, even if it is displayed that there is an empty space in a certain area, the driver does not know in which parking space row there is an empty space, and the driver has to search for an empty space while repeatedly stopping at a low speed on the main road. I could not park smoothly.

    Therefore, in the parking lot guidance apparatus disclosed in Patent Document 1, while an in-vehicle wireless device is mounted on a vehicle, a plurality of parking lot wireless devices are installed along the roadway of the parking lot, and an indicator lamp is installed in each parking space. The empty parking space is determined wirelessly from the vehicle, and the vehicle is guided by turning on the indicator lamp. However, when wirelessly guiding to an empty parking space, it is necessary to install a plurality of radios in the parking lot, and each vehicle must be equipped with radios. It cannot be applied to parking lots.

    Moreover, in the parking display apparatus of patent document 2, while installing a projector in each parking space, the light-emitting body light-emitted with the light of this projector is embed | buried in the roadside, and in the state of presence, it is a vehicle parked. The light from the projector is blocked, and it is possible to know the specific position of the empty parking space depending on whether there is a light-emitting body at the entrance of the road. However, when displaying an empty parking space with a light emitter embedded in the roadway, the display cannot be seen from a location away from an empty parking space, such as the entrance of a parking lot, and at least the entrance of the roadway There is a problem in that it is necessary to go to the vicinity, and when the vehicle is full, it is necessary to search for the illuminant that is issued by traveling along the parking lot. In addition, it is necessary to embed the light emitter in the roadway so as not to obstruct the traveling, and there is a problem that the installation cost is increased.

    Further, in the display device of Patent Document 3, an on-vehicle detection sensor for detecting the presence or absence of an empty vehicle is provided in each parking space, and an on-vehicle or empty vehicle indicator lamp that displays the detection result of the on-vehicle detection sensor is parked at four locations. A single column is installed in the center of the space above the parking space. The indicator lights corresponding to the parking space are lit and displayed in accordance with the situation of the empty and existing vehicles. However, in order to turn on the indicator lamps corresponding to the parking spaces, one display device is required in the four parking spaces. In a large-scale parking lot, many display devices are set up in addition to the indicator lights. Since the same number of parking spaces are lit, it is a complicated system for the driver to imagine the position of the empty parking space and the route to it. There is also the problem of high installation costs.

Further, in the display device of Patent Document 4, empty and full information of the vehicle sensor installed for each parking space is arranged in a row in the vehicle travel path with a display that summarizes each parking space or a plurality of adjacent parking spaces, It is made visible at a glance from the entrance of the running passage to recognize which parking space is available. In addition, an indicator is displayed at the intersection of the traveling passage to indicate that the parking space along the traveling passage is vacant if there is a vacant space, and full when the parking space is full, indicating which traveling passage you can enter to park. An indicator is provided at each intersection from the parking lot entrance to the parking space, which makes it possible to reach the empty parking space by going to the intersection.
However, in the above invention, it is necessary to install a fullness indicator for each parking space or a plurality of adjacent parking spaces in the traveling passage, but information that there is an empty space in the parking space along the traveling passage is If it is given to the driver, the driver can find an empty space and park smoothly without feeling any stress while running along the road of traffic. Therefore, there is a low necessity for an empty indicator that collects each parking space or a plurality of adjacent parking spaces, and there is a problem that the installation cost is high economically.
In addition, the indicator provided at the intersection of the traveling passage has a problem that it is difficult to install in the outdoor parking lot, except when installing on the ceiling of the indoor parking lot.

Further, in the parking lot control device of Patent Document 5, an empty parking space is detected by a parking sensor, a vehicle position is detected by a vehicle sensor, and a traveling direction and distance from the vehicle position to the empty parking space are displayed by a direction guide device. However, there are problems such as a need for a vehicle detection device and a high installation cost, and a section on how to display when there are a large number of vehicles in the travel path.
JP 2003-6795 A JP 2000-265699 A JP 2005-264434 A JP-A-9-35194 Japanese Patent Laid-Open No. 5-298598

    Therefore, an object of the present invention is to economically provide a display device that smoothly guides a driver to a parking space line having an empty parking space in a large-scale self-propelled parking lot.

    In order to solve the above-described problem, in the present invention, a parking space block is provided that includes a vehicle presence detection sensor that detects a vehicle that is installed in a parking space and an empty vehicle, and a parking space block including two parking space columns is used as one display unit. The sky and fullness of the parking space column are displayed on a set of display devices.

    The guidance display device was installed at the end of the parking space block branched from the main road and entering the runway between the parking space rows, so that it can be easily seen from the entrance of the parking lot.

    The guidance display displays the parking space block empty and full at the center, and displays the parking space block empty and full on both sides, so that the parking space block empty, full and empty at a glance. When there is a space, it is now possible to determine which parking space row has an empty space.

    Also, in large parking lots, the parking space block empty and full are displayed at the parking lot entrance in the parking space block guide map, which is a schematic diagram of the parking lot, and the concept of the journey to the parking space block with empty space is shown to the driver. You may make it give.

    With the above guidance display device, the driver can recognize where there is an empty space in the parking space block of the parking lot at the parking lot entrance, and after entering the main road that the empty parking space block faces, You can easily recognize whether an empty parking space line is available. As a result, the driver can slowly park the runway between the parking space trains, find an empty parking space, and park smoothly.

    In parking lots with relatively few parking space blocks, the guidance display device may be placed on the road surface like a street light instead of being mounted on the column.

    In the case of an indoor parking lot, a guidance display device having two parking space columns facing each other across the runway as a display unit is attached to the ceiling on the runway.

    In this case, consideration should be given to the mounting angle and display contents so that they can be seen from either of the intersecting runways.

    Communication between the presence sensor, the display device, and the parking space block guide map may be performed by a wired device as well as by a built-in wireless device.

    Since the parking space block and the parking space row that composes it can be recognized from the far parking entrance, the driver can easily reach the empty parking space row and smooth parking is possible. The equipment can be provided economically.

    Hereinafter, embodiments of the present invention will be described with reference to the drawings.
