Abstract

Abstract: [PROBLEMS] To automatically send emergency information to a center based on a signal from an airbag sensor or a collision sensor that is mounted on a vehicle and detects occurrence of an accident, and to transmit current vehicle position information and data of a registered vehicle. In the transmitting emergency notification system terminal device, the power supply to the sensor for detecting the occurrence of the accident is conventionally cut off when the accessory power supply of the vehicle is turned off, so that the emergency notification cannot be transmitted by activating the sensor. The power supply to the emergency notification system terminal device 1 is performed from the battery of the vehicle. However, since it is configured to operate even when the accessory switch of the ignition switch is turned off, the sensor power supply control unit 16 is provided. Then, the power supply cutoff timing to the sensor unit 5 is synchronized with the power supply cutoff timing of the emergency notification system terminal device 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mounted on a vehicle such as an automobile, and is used in an emergency such as a traffic accident or sudden illness.
The present invention relates to an emergency call system terminal device and an emergency call system for transmitting data on current vehicle position information, registered vehicles, and the like to a center that controls an emergency call system such as a fire department.

[0002]

2. Description of the Related Art Conventionally, a telephone call processing is carried out via a base station of a telecommunications carrier to a center which is mounted on a vehicle such as an automobile and has a jurisdiction over an emergency call system such as an emergency call center in police and fire departments. 2. Description of the Related Art There is known an emergency call system terminal device provided with an emergency call notification unit. Emergency call system terminal device, when an emergency situation occurs, pressing the emergency call transmission button to manually perform the transmission process,
In some cases, transmission processing is automatically performed by a signal input from a sensor unit such as an airbag sensor or a collision sensor. In addition, the power supply of the emergency notification system terminal device can be transmitted when the vehicle is stopped, as well as when the vehicle is stopped. Power is supplied from a dedicated auxiliary battery.

[0003]

However, in the conventional emergency call system terminal equipment, the power supply of a sensor unit such as an airbag sensor or a collision sensor for outputting a start signal for performing an automatic emergency call is provided by an ignition switch of the vehicle. Therefore, when the accessory power is turned off, the power supply is cut off, and in the case of an accessory power off accident, it is impossible to make an emergency call by activating the sensor unit.
An accident when the accessory is turned off is, for example, at night or the like, when the vehicle's engine is stopped and a rear-end collision occurs with another vehicle while the vehicle is stopped on the shoulder of the road.In such a case, an airbag sensor, a collision sensor, or the like is used. Since the sensor section does not operate, automatic emergency transmission cannot be performed.

An object of the present invention is to solve such problems in the prior art, and an emergency call system terminal device and an emergency call system capable of performing an automatic emergency call by activating a sensor unit even when accessory power is off. The purpose is to provide a system.

[0005]

In order to solve the above-mentioned problems, an emergency call system of the present invention supplies and shuts off power to an accessory by supplying and shutting off power to a sensor unit at the same timing as an emergency call system terminal device. Power supply to the sensor unit can be continued even afterwards, and an automatic emergency call can be realized by starting the sensor unit.

Outputs to the control unit 12 a signal indicating that the button has been pressed by the user. The control unit 12 recognizes that there has been an emergency call request from the operation signal from the emergency call transmission button 3 and starts the emergency call process. The control unit 12 outputs a signal requesting the current position information to the position information acquisition processing unit 14. In response to the position information request signal from the control unit 12, the position information acquisition processing unit 14 inputs data from the gyro sensor 13 that generates information such as the traveling direction and direction of the vehicle, and the GPS receiver 17 4 to input data such as position information generated from the data received from. Further, the position information acquisition processing unit 14 outputs data such as the traveling direction and direction of the vehicle input from the gyro sensor 13 and data such as position information input from the GPS receiver 17 to the control unit 12. The control unit 12 includes a storage unit 15
Then, the telephone number of the center that has jurisdiction over the emergency call system such as the police and the emergency call center is obtained, and a call request is made to the emergency call communication means 11 using the telephone number. Emergency call notification means 11 uses telephone antenna 2 to start a telephone call process to the other party corresponding to the telephone number via the base station of the communication carrier. When receiving an outgoing call response from the other party or a signal such as a busy signal that shifts to a busy state, the emergency call notification unit 11 recognizes that the state has shifted to the talking state, and shifts to voice call control or data communication control. At the same time, it outputs a signal to the control unit 12 to notify that the call has been transferred. The control unit 12 determines that the call is successful, and obtains information such as the traveling direction and direction of the vehicle obtained from the position information acquisition processing unit 14,
And processing for transmitting data such as position information to a center that has jurisdiction over the emergency call system, such as the police or the emergency call center, which is the call partner corresponding to the telephone number, via the base station of the communication carrier.

In the sensor unit 5 such as an airbag sensor or a collision sensor, the operation of the sensor unit 5 is the same when the emergency notification system terminal device 1 is operating when the accessory power is supplied and after the accessory power is shut off. In addition to manual transmission of the emergency call transmission button 3,
Automatic transmission processing by activation of the sensor unit 5 is also possible. Further, when the emergency notification system terminal device 1 stops, the operation of the sensor unit 5 also stops.

As described above, according to the present embodiment, the sensor power supply control unit 16 that controls the power supply timing to the sensor unit 5 at the same timing as the power supply timing to the emergency notification system terminal device 1 is provided. Therefore, even after the accessory power supply is shut off, the power supply to the sensor unit 5 is supplied, and the automatic emergency notification by the activation of the sensor unit 5 can be realized.

In this embodiment, in the sensor unit 5 such as an airbag sensor or a collision sensor, the emergency notification system terminal device 1 is stopped when a certain period of time has passed after the accessory power supply is shut off, and the engine stop when the engine is stopped. In the case of a system for reducing power consumption, control to stop the operation of the sensor unit 5 is performed in accordance with the timing by outputting a power cutoff or stop control signal from the sensor power control unit 16.

The sensor unit 5 includes an airbag sensor and a collision sensor for detecting extreme acceleration / deceleration at the time of a collision, a rollover sensor for detecting a certain degree of inclination such as a vehicle rollover, a fire, and the like. It is possible to use a temperature sensor or the like that detects a certain or more temperature rise.
