DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency vehicle such as an ambulance, a fire engine, a police car, etc., when an emergency is dispatched, to make the vehicle proceed safely and promptly. In order to inform the general vehicle, the switch of the installed transmitter is turned on at the same time as the operation of the siren, red rotating light, etc., the radio wave of the specified frequency and electric field strength is transmitted, and the radio wave emitted from the vehicle is transmitted. Normal vehicles such as passenger cars, trucks, buses, motorcycles, etc. are received by a receiver mounted on the vehicle, and the received radio waves are converted into alarm sound, sound, vibration, blinking light, etc. It relates to a method for surely informing the driver.

[0002]

2. Description of the Related Art When an emergency vehicle such as an ambulance, a fire engine, a police car, etc. is dispatched, a siren is simply sounded, a red rotating light is lit, and the progress is notified to a general vehicle such as an ordinary passenger car truck, bus or motorcycle. Was urged not to hinder the progress of the project.

In addition, when an emergency vehicle of this kind is dispatched, a siren is simply sounded, a red rotating light is lit, and an ordinary vehicle, truck, bus, motorcycle, etc. Although he was urged by ordinary vehicles, he did not notice the siren sound emitted by the emergency vehicle or the red rotating light and continued to drive without taking over behavior, thereby preventing the emergency vehicle from proceeding smoothly.

[0004] In addition, even if an emergency vehicle of this kind is traveling in an emergency and a traffic signal indicating the traveling direction of the vehicle at the intersection shows red, the vehicle can proceed, but the traffic signal on the road intersecting at the intersection is blue. Is displayed, the driver of ordinary vehicles such as passenger cars, trucks, buses, motorcycles, etc. does not notice the siren sound emitted by the emergency vehicle or the red rotating light and continues driving without taking over behavior. As a result, the number of collisions between an emergency vehicle such as an ambulance, a fire engine, a police car and the like and a general vehicle such as an ordinary passenger car, a truck, a bus and a motorcycle is increasing.

[0005]

Conventionally, when an emergency vehicle of this type is urgently dispatched, ordinary vehicles such as ordinary passenger cars, trucks, buses, motorcycles, etc., aim for smooth travel without hindering the travel of the vehicle. As a method adopted by ordinary vehicles, trucks,
Conventional vehicles, such as buses and motorcycles, were notified of the progress of the vehicle, and were asked to change lanes or stop the vehicle, thereby securing a path for emergency vehicles. However, there was a problem that the driver could not notice the siren sound or the red rotating light or noticed it late, and could not safely and quickly yield the course to an emergency vehicle.

In addition, the siren sound emitted from this type of emergency vehicle is measured at a distance of 20 m from the vehicle in accordance with the supplementary provisions of the Road Transport Vehicle Law enacted in 1951 and the provisions of the safety standards for road transport vehicles. The volume is over 90 horn and 1
With a brightness of 20 horns or less, the red rotating light has a brightness that can be confirmed at a position 150 m away. The red rotating light was revised from December 1973 to a brightness that can be confirmed from a distance of 150 m from the conventional 150 m, but the siren sound standard has not changed, and a siren that emits a loud sound that exceeds this There is a problem that it is difficult to equip it because it has a great effect on residents in the neighboring area where emergency vehicles travel, and on nearby facilities such as hospitals and schools.

Further, the supplementary provisions of the Road Transport Vehicle Law and the safety standards for road transport vehicles were enacted. Car radios and car stereos, which were hardly equipped at the time of 1951, are now used for most ordinary cars, trucks, Spread to general vehicles such as buses, and furthermore, car coolers and car air conditioners,
The spread of air purifiers has been remarkable, and as the performance of vehicles has improved, the degree of airtightness inside the vehicle has increased, and noise outside the vehicle has been cut off. Even the siren sound emitted from the vehicle has become difficult to hear, and there has been an adverse effect that even when an emergency vehicle is traveling, it is not possible to immediately proceed to the evacuation action.

The present invention relates to an ambulance, a fire engine, a police car,
When emergency vehicles such as are dispatched for emergency rescue activities and fire fighting activities, ordinary vehicles such as ordinary cars, trucks, buses, and motorcycles can safely and promptly perform smooth emergency activities without hindering the progress of emergency vehicles. The purpose is to secure the path of the emergency vehicle so that it can be performed.
