Abstract

PROBLEM TO BE SOLVED: To discriminate whether an accident occurred on a freeway or a general road, which are parallel, by transmitting by radio present position information on a vehicle and freeway travel mark information when the accident is detected. SOLUTION: When an urgent report switch 5 is operated while a vehicle travels, or when an accident occurs and a shock sensing sensor 4 senses the shock of not less than a prescribed one and a freeway travel switch 3 is operated, a controller 1 radio-transmits an urgent signal formed of a code showing freeway travel with the identification code, the car type code, the accident occurrence code of the previously registered vehicle and the present position information code of the vehicle through communication equipment 6. When a freeway travel switch 3 is not operated, the controller 1 transmits by radio the urgent signal formed of the code showing general road travel with the vehicle identification code which is previously registered through communication equipment 6. The freeway travel switch 3 is operated when the driver of the vehicle invades a freeway.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency report system for reporting position information of a vehicle accident as an emergency signal when an automobile accident occurs. The present invention also relates to an emergency notification system that can determine which road has an accident.

[0002]

2. Description of the Related Art Conventionally, when a vehicle accident occurs on a road, the accident is detected by an impact detection sensor mounted on the vehicle, the position of the vehicle accident is measured by GPS positioning, and emergency position information is rescued. A system for wirelessly transmitting a signal has been proposed.

[0003]

The conventional vehicle position is determined by GP.
In the vehicle accident notification system that performs positioning in S, when a general road is parallel to a highway, for example, even if a vehicle accident occurs on the highway and accident information including position information measured by GPS is transmitted, However, the monitoring center that has received the accident information cannot determine which road, that is, the highway lock or the general road, on which the accident vehicle is located, and cannot determine which road the emergency vehicle should be rushed to. There was a problem.

[0004] In view of the above problems, the object of the present invention is to provide a surveillance center for determining on which road an accident occurs when an accident occurs, especially when an expressway and a general road run side by side. It is to provide an emergency call system which can be determined by the following.

[0005]

In order to achieve the above object, a vehicle accident detection sensor for detecting a vehicle accident, a GPS device for measuring a current position of the vehicle, and a highway traveling identification for identifying traveling on a highway are provided. Means, and a wireless transmission unit, wherein when the vehicle accident detection sensor detects an accident, the wireless device wirelessly transmits the information by the highway traveling identification means together with the current position information of the vehicle.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the emergency notification system according to the present invention will be described below with reference to the drawings. FIG. 1 is a system configuration diagram of the emergency call system according to the present invention.

[0007] 1 is a control device, CPU, ROM, RAM
And connected to the following units. 2 is GPS
A positioning device measures the latitude and longitude using a GPS (global positioning system) using satellites. 3 is
A highway driving switch that is operated when the vehicle enters the highway, an impact detection sensor that detects when the vehicle receives a predetermined impact or more due to an accident or the like, and an abnormality other than a vehicle accident, for example, An emergency notification switch, which is operated in case of sudden illness, etc., is a communication device. An emergency signal consisting of the indicated code or the like is transmitted to an external monitoring center by a mobile phone device or another wireless signal. Reference numeral 7 denotes a battery for backing up a power supply when power supply from a battery mounted on the vehicle is stopped due to an impact at the time of occurrence of an accident.

Next, the operation of the present system will be described with reference to the flowchart shown in FIG. When a power switch (not shown) of the control device is turned on, the control device 1 starts, and
The current position information is acquired from the GPS positioning device 2 and stored in a RAM (not shown). (Step S1)

Next, it is determined whether or not the shock detection sensor 4 has detected a shock more than a predetermined amount and whether or not the emergency notification switch 5 has been operated.
Returning to step S1, the current position information is taken into the RAM from the GPS positioning device 2 and stored and updated. This update is performed, for example, every one second. If the emergency call switch 5
Is operated or when an accident occurs, that is, when the impact sensor 4 detects a predetermined or more impact in step S2, the control device 1 reads out the current position from the RAM (step S3), and then runs on the highway. It is determined whether the switch 3 has been operated (step S
4). The highway driving switch 3 is operated when the driver of the vehicle enters the highway.

Here, when the highway driving switch 3 is operated, the control device 1 controls the identification code (for example, the vehicle number) indicating the identification of the vehicle registered in advance, the code indicating the vehicle type, and the occurrence of an accident. An emergency signal including a code and a code indicating the current position information of the vehicle and a code indicating highway driving is wirelessly transmitted via the communication device 6. (Step S5)

When the highway driving switch 3 is not operated, the control device 1 stores the identification code of the vehicle, a code indicating the type of vehicle, a code indicating occurrence of an accident, and current position information of the vehicle. An emergency signal consisting of a code indicating general road travel together with the indicated code is wirelessly transmitted via the communication device 6 (step S6).

At a monitoring center (not shown) which has received the emergency signal, the vehicle position is displayed on the map of the display from the current position information of the vehicle, and the vehicle number, the vehicle type, the accident occurrence information and whether the vehicle is traveling on a highway or a general road are displayed. Is displayed. At a monitoring center, for example, if an accident occurs in a place where an expressway and a general road are parallel to each other, it is easy to determine which road the accident occurred, so emergency activities such as arranging emergency vehicles can be performed. Can be done quickly.

In this embodiment, whether or not the vehicle is traveling on the highway is determined by operating the highway travel switch 3 by the driver. However, the present invention is not limited to this. May be installed in advance so that when the vehicle enters the highway, the signal is received and the travel of the highway is automatically stored.
