To prevent voice dialing during normal conversations on a phone with voice dialing, a phone can only be dialed after pressing a specific button, such as a send. Therefore, in the event of a vehicle crash, it is necessary to press the button of the phone on behalf of the driver, such an actuator 27 performs the function.

This actuator 27 may typically include a mechanism to fix the telephone. It may also include a vehicle hand-free device that is commonly used.

The voice output unit 25 inputs voice information of a place where a person can be rescued or an occupant's contact information to a mobile telephone having a voice dial function using a speaker of a vehicle. Also, when the phone connection is confirmed, voice information such as the accident location and the accident time of the vehicle is input to the mobile phone. It is possible to operate using backup power supply in consideration of disconnection of vehicle battery during vehicle crash.

The vehicle accident detection unit 22 may use a mechanical acceleration sensor to detect the moment of collision of the vehicle. This sensor is switched on by an acceleration value of more than -6G in one direction. When the detector is turned on by the collision, the signal is input as a signal that triggers an external interrupter of the controller 30, that is, the CPU.

In case of emergency, the port is turned on in case the vehicle battery power is cut off and the system is operated as a power backup unit 28 as a power source.

The voice input unit 26 is a device that is configured by a small microphone or the like so that the sound of the telephone can be transmitted to the control unit 30. The controller 30 may dial the mobile phone from the voice signal input through the voice input unit 26 and check whether the mobile phone is successfully connected to the place where the mobile phone can be remedy or the contact information of the occupant.

The user button 23 allows the user to press the button directly when the vehicle accident detection unit 22 does not operate to force the call. It is also possible to block the call being sent by voice in the event of an accident at the driver's will. This can be used when it is determined that the driver does not need to be rescued depending on the condition of the vehicle accident.

The time measuring unit 32 incorporates a clock IC that can designate a time of at least one second interval inside the system. That is, it provides the current time at the time of the accident to be transmitted. The accident time can be used as a means of distinguishing it from other accidents at the fire station. In some cases, the GPS can receive time. The time measuring unit 32 may be controlled by the control unit 30.

The record storage unit 24 is composed of a CD-ROM or a flash memory, and records the telephone number of the place where emergency relief is possible, for example, 119, the subscriber's home number, a hospital, an insurance company, and the like. In addition, personal information of the driver / passenger specified in advance, special status conditions, and the like are recorded. In addition, in case of calling these organizations, the audio output necessary for each situation is recorded. When the content is output through the voice output unit, the other party can understand it as a clear voice.

The emergency distress light 31 is a light that can let a person around the vehicle recognize that the vehicle is in an emergency state.

The power backup unit 28 supplies power to the device according to the present invention when the battery of the vehicle is disconnected due to the accident of the vehicle.

The backup battery 35, which is separate from the vehicle battery 33, is charged using a rechargeable battery, and is usually charged using the charging circuit 29, and the power of the vehicle is cut off due to a breakdown of the power system by a collision. In this case or when the detection switch is turned on in the vehicle accident detecting unit 22, a signal is transmitted from a port of the control unit 30 to supply power through the switch 36. Power charging of the battery 35 is controlled by using a charging control circuit to be charged with a constant current by using the charging circuit (29).

Figure 4 shows an embodiment of an automatic accident transmission system according to the present invention.

In step S101, an initialization process is performed, and in step S102, whether the vehicle accident detecting unit 22 is operated is detected. In step S103, it is checked whether the user has pressed the user button 23 for the reason of an emergency distress or the like. In step S104, the power supply circuit is first disconnected from the charging circuit 29 which is normally connected to the backup power supply unit 28. At the same time, the emergency distress light 31 is operated, and in step S105, first, by operating the phone by pressing the operation start / end button of the mobile phone by using the button actuator, the voice recognition is enabled and registered in the mobile phone in advance using the voice dial function. The "recognition voice" is extracted from the recording storage unit 24 and output to the voice output unit 25 to attempt a telephone connection. For example, output "119" to connect 119 or the driver to a phone number registered in advance. In step S107, the voice connection unit 26 recognizes the connection sound generated by the mobile phone and checks the connection state. If there is no connection, the process proceeds to step S106 and compares with a preset number of repetitions. If the number of repetitions has elapsed, the same number or another telephone number recorded in the recording storage device is fetched in step S201, and the process proceeds to step S105 or terminates if there is no telephone number to be connected. In step S108, the current latitude and longitude of the vehicle is read from the GPS, and the accident time is read through the time measuring unit 32. The voice data stored in the recording storage unit 24 is drawn out by the control unit 30 to make a sentence and output through the voice output unit 25. The sentence here is, for example, "vehicle distress report. A collision occurred at the current location latitude 00, longitude 00. Accident time is 00: 00. This situation is an emergency. Sending ... "etc. can be used. In step S109, the receiver checks whether the voice content has been received. For example, after transmitting the voice "If you receive this information and urgent action is possible, please press the button 9" and check the frequency of the voice and the like through the voice input unit 25 whether the button 9 was pressed. In step S110, the driver's personal information and the like stored in advance in the record storage unit 24 make a sentence and output it through the voice output means. The sentence can be used, for example, "the driver is a type 0 diabetic with age 00". In step S111, the receiver checks whether the voice data of step S110 is received. For example, after transmitting the voice "If you receive this information and urgent action is possible, please press the button 8" and check the frequency of the voice and the like through the voice input unit 26 whether the button 8 was pressed. In step S112, as a step of terminating the connection state, for example, a voice such as "Press button 2 to transmit the contents of the call and button 3 to terminate" is output through the voice output unit 25. If the call ends, the caller ends the call and ends the call using the start / end button.

According to the present invention, the accident information of the vehicle is automatically transmitted by using the function of the navigation device and the voice dialing function of the mobile phone, so that the accident vehicle can be rescued without any extra space or excessive expenses.

In addition, the present invention can provide a comfortable driving environment to the driver by reducing the human loss due to the occurrence of the accident vehicle to the maximum, there is an effect that can maintain the comfort of the road environment through the rapid road clearance in the event of an accident.
