Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency vehicle travel notification system, and more particularly to an emergency vehicle approach display and a purpose display on a screen of a car navigation device, and the movement of a general vehicle on the emergency vehicle travel route. The present invention relates to a traveling notification system for an emergency vehicle, which enables early measures such as use of another road.

[0002]

2. Description of the Related Art Conventionally, an emergency vehicle such as a police car, a fire engine, an ambulance, etc. travels to a site where an incident or accident has occurred or a hospital.
The onboard car navigation equipment is used to select routes to arrive at the target site in the shortest possible time.

On the other hand, a driver of a general vehicle recognizes the approach and the traveling direction of the emergency vehicle by visually and audibly detecting an emergency sound (siren) emitted by the emergency vehicle, lighting confirmation of an emergency lamp, and the like. Therefore, it could be recognized only within the normal sense range of the human five senses.

Recently, VICS (Vehi) has been used by utilizing the car navigation of general vehicles, which has been rapidly spreading recently.
cle Information & Communication System: VICS Center is an optical beacon installed on general roads led by the National Police Agency, a radio beacon installed on expressways led by the Ministry of Construction, and a FM multiplex controlled by the Ministry of Posts and Telecommunications. Vehicles equipped with VICS-compatible car navigation equipment (for example, a car navigation device equipped with an FM multiplex broadcast receiving circuit) using various media for broadcasting (used to provide wide area information for the entire broadcasting area using broadcast waves of the Japan Broadcasting Corporation). Provides traffic congestion area information, road guidance, weather information, and the like. In the VICS-compatible car navigation device, information is provided in various forms, such as providing information using characters, providing information using simplified map data, and providing information in a form in which traffic congestion is overwritten on a map displayed by the car navigation device. Information is available free of charge.

However, even with the use of VICS, only information about the degree of traffic congestion due to incidents, accidents, emergency vehicles, etc. can be transmitted.

In Japanese Patent Laid-Open Publication No. Hei 10-74299, an emergency vehicle is deployed, and the station where the emergency vehicle is dispatched is V.
The route information of the emergency vehicle is sent to the ICS center, and the VIC
The S center notifies the vehicle using a radio beacon transmitter, an optical beacon transmitter, and an FM multiplex broadcaster, and enables the vehicle to quickly obtain information on the route and time that the emergency vehicle will pass through, Vehicle passing warning technology has been proposed.

[0007]

As described above, the conventional emergency vehicle notification mode has the following problems.

[0008] The first problem is that when an emergency vehicle is running, the only way to notify a general vehicle on the road is to emit an emergency sound or to turn on an emergency lamp, and the emergency vehicle is recognized only by the driver. Relies on the five senses, so the distance that can be reported is
That is, it is limited to the human audiovisual range. As a result, it is difficult for a general vehicle to recognize the approach of an emergency vehicle at an early stage and take necessary measures in advance.

[0009] The second problem is that even when the notification by the current VICS (road traffic information communication system) is used,
It is broadcast from a fixed station and has very little relevance to incidents, accident scenes, and emergency vehicles.

[0010] A third problem is that information from the VICS can be obtained only by accidental switching of an at-random switch (channel) by a driver of a general vehicle, resulting in poor reliability.

As a fourth problem, the above-mentioned Japanese Patent Application Laid-Open No.
In the system described in Japanese Patent No. 4299, the current traveling direction, speed, position information, and the like from an emergency vehicle cannot be notified to a general vehicle in real time.
